Introduction Hon'ble Prime Minister of India, Dr. Manmohan Singh in his speech on the occasion of Technology Day Celebrations, 12 May 2008 stated that: “The fruits of our technological progress must also reach to the common man. This is the only way in which we can make every citizen of India a productive participant in India's growth story. DRDO has a crucial role to play in leading by example”. Defence Research and Development Organization (DRDO), the R&D arm of Ministry of Defence, Government of India joining hands with FICCI - the apex industry chamber of India, by initiating a "Accelerated Technology Assessment and Commercialization (ATAC) Programme" for the Assessment of DRDO developed technologies for commercial markets is the first step taken by DRDO in this direction.

DRDO - FICCI ATAC programme aims: ? To create a commercial pathway to deliver technologies developed by DRDO for appropriate commercial markets for use in civilian products and services. These markets may be in India and abroad. ? To enhance the spirit of innovation within the ranks of DRDO Scientists and agencies. ? To facilitate the growth of the organization as a technology provider. This programme is first of its kind to be undertaken by DRDO in association with FICCI to actively spinout several of DRDO's technologies for appropriate commercial markets both nationally and internationally. In the very first year of operation of the programme as many as 26 DRDO labs across India have participated and over 200 technologies are being assessed under this programme by FICCI. The technologies that are currently assessed are from sectors as diverse as electronics, robotics, advanced computing and simulation, avionics, optronics, precision engineering, special materials, engineering systems, instrumentation, acoustic technologies, life sciences, disaster management technologies, information systems, etc. Under a unique process of technology Accelerated Technology Assessment and Commercialization (ATAC), FICCI along with the IC2 Institute of University of Texas at Austin has identified technologies which were initially only exposed to the defence sector but have large commercial potential also . The ATAC programme jointly initiated by DRDO and FICCI has received very encouraging response from the Industry for acquiring the technologies selected under the programme. Several NDAs, MTAs, BEAs have been signed. MoUs have been finalized for various technologies including DEPA Multi Insect Repellant Cream, RO based mobile water purification system, Explosive Detection Kit and HAPO chamber. (iii)

While DRDO continues its effort in developing cutting edge technologies for Indian Armed Forces, it has started to actively pursue spinning out relevant DRDO developed technologies for non military applications. This in the long run will help the industries to produce high quality, high reliable industrial products and systems at an affordable cost. A proposal for providing incentives to those scientists who are behind these innovations is also on the anvil and DRDO hopes to introduce it soon. The products and technologies under ATAC process have been selected very carefully after due diligence and a number of deliberations to ensure that the common man benefits from these technologies developed by the brightest minds of DRDO. Through the ATAC initiative, DRDO has enabled the industry to leverage the knowledge and capabilities developed by its scientists and technologists. The transfer of technologies to the Indian industries will enable them to be technologically self reliant and would enable them to contribute effectively to economic growth of the country. DRDO has done phenomenal innovation work for creating a large degree of self-reliance for the Indian defence. There are many innovative technologies within the DRDO framework, which could lead to significant success in the civilian side as well. This programme is an attempt to make that happen. This commercialization framework could be institutionalized in the interest of Indian Industries and society at large.

Africa Initiative The Indian Prime Minister's Opening Statement at the India-Africa Forum Summit in April 2008 and his visit to Africa in May 2011 paved new ways for Indo-African collaboration. The Indian government's initiative of offering a $5 billion line of credit over the next three years to the African region was a major milestone in this regard. Subsequent to a cabinet decision after the Prime Minister's Africa visit, various initiatives have been taken to further strengthen Indo-African ties. The Defence Research & Development Organization (DRDO), the Research arm of the Ministry of Defence, Government of India, is committed towards taking the vision of the Hon'ble Prime Minister to a concrete reality. DRDO and FICCI, working under the banner of the ATAC Programme, have started taking joint initiatives in this direction and DRDO's recent participation in the India-Africa Business Partnership Summit at Hyderabad during October 12-13, 2011 is a strong testimony towards its commitment to forge strong Indo-Africa ties. Further, DRDO intends to participate at the forthcoming 'India Show at Nigeria' to be held at Lagos, Nigeria between 02-03 February, 2011. 46 technologies currently identified for commercialization through ATAC process are covered in this compendium. They are from varied sectors, including Communications, Electronics, Materials, Medicines, Mechanical, Medicine/Health Sciences, Security & Surveillance, and Waste Management/ Environment

'Aahar' Initiative Under the DRDO- FICCI Accelerated Technology Assessment and Commercialization (ATAC) Programme, Defence Research and Development Organisation (DRDO), BASIX - a Social Enterprise Group, and Federation of Indian Chamber of Commerce and Industry (FICCI) have come together to collaborate on long term basis to develop and execute viable and scalable models for commercialization of the technologies developed by DRDO with the specific intent of developing and enhancing livelihoods. The three partners will identify and commercialize sub-set of technologies/products/processes developed by DRDO focusing on the base of the pyramid as both producers and consumers and thereby improving the lives of the disadvantaged and creating livelihoods for them. Initially, this collaboration will focus on the food technologies developed by Defence Food Research Laboratory (DFRL), formed under the aegis of DRDO. The aim of the project is to build womenoriented enterprises using food technologies of DFRL. The first pilot under this collaboration is the project 'Aahaar' that encompasses a set of technologies and products including ready-to eat Roti, and two variants in dal - instant Palak Dal with Masala Channa curry mix. BASIX shall subject the identified technologies/products/processes to three levels of testing viz. Technical Feasibility, Economic Viability and Consumer Acceptance. BASIX will play the lead execution role in bringing together all aspects of this project and conduct the commercialization pilot. The pilot will involve developing a model of creating small production units comprised predominantly of women, by organising and building of a range of skills and deploying simple technologies developed by DFRL. For the consumer, Aahaar is a hygienic, nutritious and convenient meal that tastes fresh yet has longer shelf life, and is tasty and quick to serve. Roti has a shelf life of 15 days and the two variants of dal have a shelf life of 12 months. This is a differentiated and unique positioning in the market place in this category of foods. Dr. Montek Singh Ahluwalia, Deputy Chairman of the Planning Commission, Government of India launched 'Aahaar' on February 28, 2012 and has subsequently referred the technology to the National Advisory Council to be considered for various national programmes, particularly the Mid-day meal scheme.

3. Bio-larvicide Defence Research Laboratory (DRL), Assam Mosquito larvae are generally killed using synthetic insecticides, which are very detrimental to environment. However, development of eco-friendly mosquito larvicides would be a positive approach to maintain sustainable ecoenvironment. The lab has isolated a potential entomopathogenic soil bacteria, Bacillus sphaericus and developed a mosquito biolarvicides of 10% powder formulation using this bacteria. The identified bacteria act on mosquito larvae through its paraporal crystal delta endotoxin. The endotoxin acts on mid-gut epithelium causing disintegration of gut wall, cessation of feeding activity, starvation and leakage of gut contents into haemolymph and body cavity of the mosquito larvae causing paralysis and death. Recommended dose for field use is 200-500 gm/ha to be sprayed uniformly over the water surface of mosquito breeding site with Knapsack sprayer. Spheritox is a biological larvicide based on highly effective strain of Bacillus sphaericus GC Subgp. IV isolated from mosquito breeding habitat. The bacillus isolates were inoculated in growth media and incubated for 48 hrs and the biomass harvested was lyophllized and thoroughly mixed with filler inert material at the ratio of 1:10 and used as water dispersible powder 10%WDP. This innovation acts as a stomach poison and shows high larval mortality than other commercial formulations available in the market.

7. Electrochromic Window Defence Laboratory Jodhpur (DLJ) The technology is an electrochromic window, alternatively known as smart window. The electrochromic window can be darkened or lightened electronically and can be controlled through a remote control device. A small voltage applied to the windows causes them to darken and reversing the voltage causes them to lighten. This capability allows for the automatic control of the amount of light and heat that passes through the windows, thereby presenting an opportunity for the windows to be used as energy-saving devices. This innovation can be effectively used towards reducing electricity loads by integrating it within the buildings. It can also be used in cars for reducing the effects of headlight glares which otherwise cause visual discomfort and diminishing ability to see the surroundings during nighttime driving and during bright, sunny days. The developed EC window technology has got advantages in many folds over the existing technologies (such as liquid crystal window, thermo chromic window and photo chromic window) like (i) Dynamic control of solar transmission i.e. between 17- 70% achievable with fast switching time and low dc power consumption i.e. from 1 to 3v (ii) Control is possible through a dimmer switch or remote control device (iii) Transmits high levels of visible light while reflecting invisible solar heat and therefore provide both visual and thermal comfort (iv) Response time is very fast i.e. < 1 minute (v) The raw material Costs are comparatively less. Approx. Cost is Rs. 800/-sq. ft. and reducible on bulk production.

8. Dissipative Acoustic Silencer

Naval Science and Technological Laboratory (NSTL), Visakhapatnam The subject technology is a sound absorption device to moderate the sound effect of a machine. Noise reduction can be achieved by modification of source or path or receiver. Among these, modification of path is most practicable. For intakes and exhausts of air/gas handling systems, Dissipative Acoustic silencers is one such solution. These silencers attenuate noise in ducts through which gas/air flows by baffling process. The silencers are made up of ducts filled with spaced baffles. They work on the principle of sound absorption for reducing the noise. Dissipative acoustic silencer is a noise control device for ducts in which gas flows. Broadband sound attenuation can be achieved by using these silencers. The silencer works on the principle of sound absorption through its baffles. Each baffle consists of a perforated metallic sheet filled with sound absorbing material. Silencer attenuation takes place by ing dissipated sound energy into heat. The technique was employed in developing acoustic silencers for various shipboard equipment such as Gas Turbines and Ventilation fans. Dissipative acoustic silencer is an important noise control device which is widely used to attenuate the noise in ducts through which gas flows and in which the broadband sound attenuation must be achieved which a minimum of pressure drop across the silencer. Dissipative silencers attenuate sound by converting the acoustical energy propagating in the passages into heat. NSTL has developed acoustic silencers for Gas turbine intake and Ventilation fans. With these silencers, 10 to 12 dB (A) noise reduction was achieved.

Areas of Application These can be used for reducing air borne noise caused by air flow at the intake and exhaust ducts of gas turbine, air conditioning and ventilation ducts connected to small and large industrial fans, cooling tower installations etc.

9 . Phase Change Material (PCM) Based Cool Panel Defence Laboratory Jodhpur (DLJ) The technology is a phase change material based cool panel. PCM is a substance with a high heat of fusion, which melting and solidifying at a certain temperature, is capable of storing and releasing large amounts of energy. Heat is absorbed or released when the material changes from solid to liquid and vice versa. Thus, PCMs are classified as latent heat storage (LHS) units. PCMs can smooth daily fluctuations in room temperature by lowering the peak temperatures resulting from extreme external daily temperature changes. PCMs are solid at room temperature. When the temperature becomes warmer, PCMs liquefy and absorb and store heat, thus cooling the house (or inside of vehicles). Conversely, when the temperature drops, the material will solidify and give off heat, warming the house. By incorporating PCMs in the building envelope, they absorb the higher exterior temperature during the day, and dissipate the heat to the interior at night when it is cooler, thereby, moderating the outdoor temperatures. This technology has been tested in extreme weather conditions (for a prototype shelter of the size 240 Cm L× 12oCm W × 180 Cm H) and it has been concluded that even during acute hot days of summer, the temperature never goes beyond 40 degree C. This is an extremely useful technology having all desired properties of a PCM such as being non- toxic, non-corrosive and non-hygroscopic and can find applications in residential use, telecom shelters and vehicles, particularly railway coaches and for military use in extreme weather conditions. This technology offers several advantages such as energy saving and increase in productivity levels by making the working conditions more favorable for those employed or residing in locations with harsh, extreme weather conditions.

Areas of Application These panels can be used to reduce heat load passively on temporary and permanent buildings, telecom shelters, railway coaches and vehicles. 12

The similarities in clinical presentations, their circulation in the same geographical area and transmission through same vector necessitate an urgent need for the differential diagnosis of these two infections. The incidence of dual infection in the same individual further complicates the task of the clinicians to arrive at a definitive diagnosis. In the absence of any specific therapy or vaccine, early diagnosis is crucial for patient management. This assay is based on the principle of duplex RT-PCR, by targeting genomic regions of both dengue and chikungunya virus. This assay is developed as a one step method by combining both RT and PCR steps. Further both primers are included in the single tube, making it a one-step, single tube protocol. The presence of 511 bp indicates dengue complex and of 205 bp indicates Chikungunya infection. Presence of both amplicons suggests the dual infection in the same patient. The evaluation was carried out with more than 400 clinical samples from recent chikungunya and dengue outbreaks in India. This assay could also able to detect dual infection of CHIK and DEN in patients. This kit has potential clinical and epidemiological application for rapid, sensitive detection, differentiation and genotyping of DEN and CHIK viruses in clinical samples. The innovation is a testing kit for detection of Dengue (DEN) and chikungunya (CHIK) infection with high degree of sensitivity and specificity in a single clinical sample.

22. Herbal Adjuvant: DIP-HIP

Defence Institute of Physiology & Allied Sciences (DIPAS), Delhi The technology is a herbal adjuvant which is an agent that may stimulate the immune system and increase the response to a vaccine, without having any specific antigenic effect in itself. Adjuvant, have been used for decades as important agents for generation of strong immune response to vaccine antigens. Classically the adjuvants are determined by their ability to potentiate strong antibody response. However, besides generating strong immune response, they also act as immunomodulators by influencing the type and character of antibody generated. Therefore, the choice of adjuvant is of immense importance for the isotype and subclasses of IgGs, patterns of cytokine and recruitment of T cells. Currently, Freund's Adjuvants are predominantly used in raising antisera in animals, whereas for humans only Aluminium hydroxide (Alum) is in routine use. The lab has developed a new herbal adjuvant, called DIP-HIP, and compared its efficacy with complete Freund's Adjuvant and Alum. Animals were immunized with different antigens. The results indicated that antigens. The results indicated that antigen specific immunoglobulin levels were significantly enhanced by DIP-HIP. The cytokine profile also correlated very well with the Th1 and Th2 type of immune response generated on administration of DIP-HIP. Interestingly, using different strains and different species, DIP-HIP responded better than CFA. The sustenance of antibody response in the body was for about more than four months using DIPHIP. Immunization through different routes like intraperitoneal and intramuscular did not show any significant difference nor caused any muscular damage, granulomatous reaction or dystrophy. The shelf life of DIP-HIP as such is for more than 3 years where as in the form of formulation with and antigen is about 4 months at 40 C. There is no haemolytic activity observed on treatment of both human and animal erythrocytes with DIP-HIP.

31

Areas of Application Incorporation of DIP-HIP will result in enhancing, accelerating and prolonging the antigen specific-antibody responses in animals. The results are at par with Oil adjuvant but more significant than those of alum. Thus the new adjuvant developed can substitute oil and Alum adjuvants. Further advantages of DIP-HIP are the enhancement of immunogenicity, the reduction of antigen amount needed for a successful immunization, the reduction of frequency of booster immunization without any muscular damage or side effects.

28. Typhigen Kit

Defence Research & Development Establishment (DRDE), Gwalior Typhoid, an infectious disease caused by Salmonella typhi is a major public health problem all over the world especially for third world countries including India due to hygienic reasons, unsatisfactory water supply etc. as the disease spread by faecaloral route. Incontrovertible diagnosis of typhoid infection is based on isolation of organism from blood or urine of the suspected patient by culture and / or demonstration or rising antibody titers to 'H' and 'O' antigens by Widal test. However, isolation of organism takes 2-5 days and requires microbiological facilities, which are not always available in the area where disease is endemic. Besides, it becomes negative if patient had already been administered with antibiotics. Widal test of single serum sample is not useful in endemic areas and the detection of rising antibody titers is too slow to allow quick decision by the clinician. Therefore, a latex agglutination based detection system has been developed, using recombinant DNA technology and immunological techniques to detect typhoid antigen directly in patient's serum or plasma within 3 minutes. The system has been packed in the form of a kit, which can be used in field conditions. The kit has undergone extensive third party evaluation at premier medical institutions (AIIMS, PGI, AFMC) of the country and has been found to be highly satisfactory. The innovation, rapid diagnostic `typhigen' kit using recombinant DNA technology, enables direct detection of the salmonella typhi antigen in the patient's serum within one to three minutes, thus allowing early treatment of the affected persons. The test detects S. typhi antigen directly in patient's serum within 1-3 minutes, which is very important for initiating early treatment and saving human life. The test has been packed into a form of kit. Whereas the conventional method of typhoid diagnosis is based on the isolation of S. typhi from patient's blood or detection of antibodies by Widal test. Both tests have limitations. Blood culture is time consuming and requires culture facilities, which at times are not available in primary health centers in remote areas and hospitals. Besides, it becomes negative if patient had already been administered 39

with antibiotics. Widal test requires paired serum samples from the patient at an interval of one week and test protocol is time consuming. Besides, test is less sensitive and specified.

Areas of Application The kit is useful for early and rapid diagnosis of Typhoid fever.

In an emerging complex security environment, timely and accurate identification of all targets – friendly and hostile as well as locating threat targets – is of paramount importance. This can be achieved with the help of Interrogator system. The system consists of two sub-systems, namely the Interrogator and a Transponder. It operates as per the recommendations of Annexure 10 of International Civil Aviation Organisation (ICAO) and STANAG 4193. SSR Interrogator operates in conjunction with a compatible Transponder that is fitted on the target aircraft. The airborne interrogator transmits pulsed signal with suitable spacing as per the desired mode of interrogation in a specified direction. Aircraft fitted with compatible transponder receives the interrogation signal and replies back in the form of another coded signal. These coded replies are received by the interrogator and processed for identification. It differentiates between friendly and enemy targets, by comparing the response received from the interrogated target with its own database. It provides additional target details such as height, range and azimuth. In addition, it can extract the target status like Communication Failure, Emergency and Hijack. Operation in mode – '4' enhances its capability to be secured, jam resistant and resistant to spoofing. Mode S or mode “select”, is a way to interrogate an airframe by using a distinct address, such as an aircraft address, that only a particular airframe will respond.

37. Opto- Electronic System for Real Time Monitoring of Motions in Stratified Fluids Naval Physical & Oceanographic Laboratory (NPOL), Cochin The present invention elucidates an innovative method and system for real time monitoring of motions in stratified fluids (like waves and mean currents in the ocean and atmosphere). The novel system is applied to monitor internal waves and tsunami waves simulated in a laboratory tank filled with stratified salt water. An inter comparison of the data recorded using this invention and the data records obtained from an ocean industry standard pressure transducer, variations of which are currently being used for surface wave and tsunami wave monitoring by many researchers around the world, demonstrated the efficacy of this invention as a sensitive method for real time monitoring of ocean waves. The opto-electronic system described herein is an in situ device which could be deployed in the ocean for the real time monitoring of ocean waves like surface waves, internal waves, tsunamis etc. Ocean is a stratified fluid medium. The optoelectronic system for real time monitoring of ocean waves comprises of a (any) continuous wave, coherent, collimated beam of light (or a laser) falling on the surface of a (any) photo detector in such a way that the received light falls on the active sensing areas of the photo detector, after passing through the stratified fluid medium. That is the stratified fluid medium spatially separates the light source and the photo detector. The light intensity falling on the photo detector undergoes changes due to changes in the optical refractive gradient generated as a result of wave motions in the stratified fluid (caused by surface waves, internal waves or tsunami waves). The photo detector records the precise time varying light intensity pattern, corresponding to the time varying motions experienced in the stratified fluid due to wave motions. The output signals from the photo detector are recorded and compared with those obtained from a standard pressure sensor. The efficacy of this method and system for real time monitoring of ocean waves is demonstrated.

1. Initial oil film (HSD).

2. Complete emulsification.

3. Fragmentation & precipitation.

4. Dispersion of oil film.

Sequential change in floating oil film after treatment with NMRL technology

Naval Materials Research Laboratory (NMRL), Ambernath Hydrocarbon pollution in marine environment is known to affect man, material and marine eco-system. These hydrocarbons are known to cause permanent inheritable changes in exposed individuals leading to increased incidents of cancer, allergies, asthma and also make people vulnerable to contract other bacterial and viral diseases. NMRL has developed an eco-friendly approach for such oil spill management. The bioremediation of pollutant oil using NMRL developed technology is brought about by spraying bioemulsifier, oil degrading marine bacteria and nutrient mixture at polluted site in 3 days intervals for complete removal of oil. The oil hydrocarbons are degraded by bacterial alkane monoxygenases and associated enzymes releasing CO2 and water and no toxic substance. The other biomolecules generated get incorporated as biomass and 'Bioemulsifier' as a byproduct. Bioemulsifier is a surface active biomaterial which facilitates emulsification of oilin-water, enhancing bioavailability of oil for biodegradation in ecofriendly manner. The bioemulsifier developed is a heat stable compound (initial decomposition temperature 192ºC) having a molecular weight of ~5000 as determined in a gel permeation chromatography (GPC). The GC-MS spectrum indicated presence of 16 fatty acids which are contributing to its surface active properties. The finished material has greatly reduced the surface tension of distilled water from 72 mN/m to 30 mN/m. Areas of Application The material has become an obvious choice for bioremediation of floating pollutant oil when used along with NMRL oil-degrading bacteria and nutrient mix. The same has been demonstrated in various trials at Naval Harbour, Mumbai and Vizag. A process patent has been filled for the two materials, viz., Bioemulsifier and Nutrient mixture.

41. Ceramic-Composite Integral Armour Research and Development Establishment (R&DE), Pune The present innovation is a unique technology to produce lightweight, maintenance free and easily repairable multifunctional alternative engineered material known as Ceramic Composite Integral Armour which can be used for structural requirements and ballistic threats. The innovation is lighter and more efficient than metals and it can be integrated with the composites to provide alternative solutions to the current bulky metallic structures with add-on/strap-on armour. The present technology can be used to manufacture large and complex structural parts with integrated ceramics. This technology offers substantial weight advantages (over 40%) on the conventional technique of strap-on externally applied armour. Further, integral armour exploits the benefits of ceramics more than strap-on armour because of the additional confinement of ceramics achieved due to integration of structure and armour. The strap-on armour is made in flat rectangular pieces and cannot be applied to complex curved surfaces whereas integral armour can easily comply with complex shapes. Large structures such as armoured vehicles and assault boat hulls with complex shapes and curves can be made in few pieces with minimum joints. Features such as watertight and amphibious construction can easily be incorporated. The solution also significantly lowers the fabrication time making large-scale production cost effective. Costeffective and easy repair of damaged armour is also possible due to modular construction. Parasitic mass such as spall-liners and additional backing material for ceramics essential in strap-on armour is completely eliminated in integral armour. Further, modular construction of integral armour using small ceramic tiles allows for its easy repair after impact. The present technology is based on Vacuum Assisted Resisted Resin Transfer Moulding VARTM process for manufacture of composites structures. Ceramic-composite integral armour has ceramic layer, rubber layer, backing composites structural layer, cover layer and other functional layers such as layers for fire-protection. The whole structure along with the integral armour is manufactured in one go. The ceramic layer provides primary ballistic protection while the composites layer is the structural layer.

62

Ceramic armour is lighter and more efficient than metals. When integrated with composites, it acts as a significantly lightweight multi-functional alternative catering for structural requirements and ballistic threats. Technology has been established to manufacture large and complex structural parts with integrated ceramics. This technology offers substantial weight advantages (over 40%) on the conventional technique of strap-on externally applied armour. Further, integral armour exploits the benefits of ceramics more than strap-on armour because of the additional confinement of ceramics achieved due to integration of structure and armour. The strap-on armour is made in flat rectangular pieces and cannot be applied to complex curved surfaces whereas integral armour can easily comply with complex shapes. Parasitic mass such as spall-liners and additional backing material for ceramics essential in strap-on armour is completely eliminated in integral armour. Further, modular construction of integral armour using small ceramic tiles allows for its easy repair after impact.

43. Non-Sparking Tools / Cu- Ti Alloy

Defence Metallurgical Research Laboratory (DMRL), Hyderabad Non-sparking tools are widely used in mining, petroleum and explosive handling industries where fire hazards are to be prevented. There are a number of nonferrous materials, which are non-sparking; however, they do not possess enough strength to provide a good cutting edge. Though Cu-Be alloys exhibit sufficient strength and electrical conductivity required for non-sparking applications, they are toxic and emit invisible toxic fumes during hot working, heat treatment, machining and pickling operations due to the toxicity of Be, which causes serious health hazards such as chronic pulmonary illness. Further, Cu-Be alloys are highly expensive due to the limited resources of Be. Copper base Cu-4.5Ti alloy is mainly used for making 'non-sparking tools'. The subject technology is a Cu-4.5Ti alloy for use as a non-sparking material. Salient features of this alloy are high strength (TS: 890 to 1380 MPa), certified nonsparking material and possesses low magnetic permeability (1.26 x 10-6 H/m). Due to abundant resources of Ti, Cu-4.5Ti alloy is relatively cheaper and economical. The alloy can be manufactured with ease and without any health hazards.

Areas of Application Non-sparking tools are widely used in mining, petroleum and explosive handling industries in defence as well as civil sector.

44. Electrically Conducting Structural Foams Aeronautical Development Establishment, Bangalore The subject technology is the development of a special material for functional core material in sandwich designs for EMI shielding structural applications like electronic enclosures. The present technology involves tailoring hollow glass microspheres embedded polymeric syntactic foams for electrical conductivity applications by incorporation of certain lightweight conductive in critical quantities, so as to ensure the initiation of the electrical percolation phenomenon in the bulk materials. These additives not only render the resultant composite foams with sufficient electrical conductivity, but also reinforce them structurally. Such electrically conducting lightweight structural foams can be tuned for a wide range of densities, thermal with standability, mechanical and electrical properties by judicious selection of material compositions and chemistries. Further, these foams can also be subjected to near net shape fabrication, even for components with critical contours.

Areas of Application Core material for any lightweight sandwich structures for EMI shielding applications, including those demanding critical contours and near net shape fabrication. 1. Antistatic surfaces.

66

45. Friction Surfacing: Novel Technique for Metal Matrix Composite on Aluminium-Silicon Alloy Defence Metallurgical Research Laboratory (DMRL), Hyderabad Aluminium alloys are used in applications demanding lightweight and high strength. These applications could be in wrought or cast form. Some of the components need to exhibit wear resistance, which is dedicated by the surface property. For better wear resistance the surface should be hard. The approach to impart hardness is by hardening as well as by some surface treatment involving surface alloying, hard-face coating etc. Aluminium alloys do not exhibit wear resistance, as do not response to surface hardening heat treatments. The general approach to impart wear resistance in such situations is to build a surface layer consisting of metal matrix composites. These MMCs contain ceramic particulates. One such metal matrix that has high wear resistance is MMC with SiC particulate. Deposition of this MMC through fusion route result in the formation of Al4C3 that gets embrittled when exposed to moisture. Keeping the aforementioned in view, studies were carried out to bring the potential usefulness of friction surfacing technique to improve wear and corrosion behavior of A356 Al-Si alloy. The coatings exhibit excellent bonding with the substrate. The coating also has adequate corrosion resistance.

It has been developed and tested such that it proves that heat setting narrow fabrics (tapes & webbings) and cordages at particular conditions of temperature, time and stretch leads to improved elastic recovery property in the material. Also, the creep property of the material has been found to be improved. This makes the material particularly advantageous where the material is to be subjected to repeated loads such as rigging lines of parachutes, rigging lines of sails, ropes for mountaineering, etc.

47. Heptafluoropropane (HFC-227ea): a Halon Alternative During the past 20 years it has become widely accepted that the release of volatile man-made halocarbons (notably CFCs and bromine containing Halons into the earth's atmosphere) causes depletion of stratospheric ozone. In response to society's concern over potential effects of ozone depletion, a variety of national and international regulations have been promulgated, the best known being the Montreal Protocol- 1987 on substances that deplete the Ozone Layer. This landmark international agreement has already been revised from time to time in response to ever-worsening news about stratospheric ozone levels. The unique combination of properties associated with certain fluorinated methanes and ethanes has led to their widespread use in fire suppression systems. These fire suppression agents are characterized by high fire suppression efficiency, low toxicity, low residue formation after extinguishments, low electrical conductivity and long term storage stability. The three popular halogenated fire suppression agents are bromotrifluoromethane (CF3Br, BTM, Halon 1301),bromochlorodifluoromethane (CF2BrCl, BCF, Halon 1211) and 1,2–dibromotetrafluoroethane (BrCF2CF2Br, Halon 2402). Currently Halon-1301 (Bromotrifluoromethane, CF3Br) and Halon1211 (Bromochlorodifluoromethane CF2ClBr) are used as fire extinguishers and have high ozone depletion potential. However, because of their recent implication in the destruction of stratospheric ozone, the production and use of these life-saving agents is being severely restricted. As a result, intensive research efforts are currently underway in both the industrial and academic sectors to find suitable replacements for these agents. It is being realized world over that in the absence of Halons due to Montreal Protocol to phase out Ozone Depletion Potential (ODP) substances, the search for alternatives was begun and identified Heptafluoropropane (HFP) as one of the best and closest chemical substitute for Halons. Heptafluoropropane (HFP) is a hydrofluorocarbon and has been accepted world over for many applications due to its zero ODP, low GWP & toxicity in comparison to other chemical substitutes like NAFS-III (A blend of HCFs), PFCs (C4F10) etc. Heptafluoropropane (HFP) may find wide applications where Halon-1301, was the choice of user industries in the past.

69

To meet futuristic requirement of Defence users like Army, Air force, Navy, DRDO and PSUs & Govt. undertakings like ONGC, IOL, OIL, CIL, etc. Civil sectors like Industries & Fire Services, Educational Institutes. Halon based systems will be replaced by Heptafluoropropane based systems. Keeping the above point in view, CFEES has developed Heptafluoropropane gas which will replace halon in the existing halon based fire protection system. The preparation of Heptafluoropropane has been successfully carried out by catalytic vapour phase hydrofluorination continuously using a single tube modular reactor on a Pilot Plant scale and the product was obtained at a rate of 70g/h .For scaling up of the product the multiple tubes modular reactor can be used. Heptafluoropropane (HFP) has internationally been approved for Halon 1301 substitute for new generation fire protection systems. All international standards are now specifying HFP in their fire safety regulation both in civil & military applications. Under the Montreal protocol treaty halon production world over is banned and European Union has even brought out regulation to decommission the existing halon systems by their member countries including U.K.

49. Magnetorheological Fluid

Naval Physical & Oceanographic Laboratory (NPOL), Cochin Magnetorheological fluid is a smart fluid, which responds by changing its viscosity from liquid state to a near solid state by the application of a magnetic field within milliseconds of time. NPOL has successfully developed and patented fluid in many countries like USA, France, UK & Japan. The material is a suspension of surfactant coated magnetic particles in a carrier fluid medium. When a magnetic field is applied, the magnetic particles align themselves along the direction of magnetic flux and provide a viscosity change. Several studies made in NPOL shows that the fluid is stable and non reactive towards many of the engineering materials. Similar fluids developed by a couple of firms elsewhere are based on petrochemicals, whereas the present fluid is based on renewable agro seed oil such as or oil. The other essential additive required for formulation is also a derivative of or oil. The formulation does not contain any additive of petroleum origin, simple to make, environmental friendly and cost effective.

Areas of Applications: Magnetorheological fluid is an ideal material for developing smart brake, torque transfer devices, shock and vibration damping suspension/mount. The device made of this fluid can replace the conventional system by providing varying torque/damping force. Hence the device made of this fluid will be a smart device whose characteristic output can be turned by external magnetic filed or automated by closed loop feedback controller. This smart material can be used to develop new brake; clutch and torque transfer systems, smart shock absorbers/suspensions for automobiles for automobiles, haptic interfaces, artificial limbs, earthquakes resistant civil structures/ buildings and smart dampers for cabled bridges to counteract wind guest etc. MR fluid can be useful in: - Automotive applications, Rapid prototyping, Bio medical, Aero space, Space applications, Vibration Damping, Exercise machines and much more.

50. Magneto- Resistive Electrical Switching Fluid Naval Physical and Oceanographic Laboratory (NPOL), Cochin The subject technology is smart fluid whose electrical resistivity can be varied by order of several magnitudes by using an external magnetic field. This sharp and reversible change in resistivity make the fluid transform from an insulator to a conductor. In the presence of a magnetic field typically 0.7 tesla, the resistivity of the 8 fluid changes from 2 X 10 ohm to 1 ohm within a fraction of second. Materials with such characteristics are not reported in literature and this development is a breakthrough. The composition of the fluid includes magnetic responsive particles, conductive dopant , particle stabiliser and carrier fluid. In the absence of magnetic field, the magneto responsive electrical switching fluid has a measurable electrical resistivity. However, in the presence of an external magnetic field, the electrical resistivity of the fluid decreases to a very low value as the suspended particles align themselves resulting in rapid physical gelling of the fluid. This facilitate transport of electrons induced by the added dopents (either by mutual contact or by tunneling effect). Once the magnetic field is removed, the electron transport is no longer possible as the particles return to the disoriented pattern and it becomes an insulator.

Areas of Application This novel material has potential for several applications. Few applications that can be thought of are non arcing lighting switch for use in explosive areas (explosion proof switches), magnetic field sensors, magnetic mine activators, proximity fuses for torpedoes, over voltage protectors, tilt sensors, smart microwave absorbers, earth current leak sensors and the like.

Preparation of Cadmium Telluride Nanoparticles from Novel Single Source Molecular Precursor The Defence Materials & Stores Research & Development Establishment (DMSRDE), Kanpur The innovation is a convenient method for the preparation of cadmium telluride CdTe nanoparticles under mild conditions from a novel single source molecular precursor, i.e. cadmium II complex of bisisopropyltelluromethane and bis aminopropyl0ditelluride. The precursors are solid and non-toxic & non-explosive. Nanoparticles of CdSe, CdTe, which are the compound semiconductors of elements in group II and VI of the periodic table, have been extensively investigated because of their exclusive features such as, size-dependent emission wavelength due to the quantum size-effect and strong luminescence and these particles are expected to be applied to various fields such as informational home electronics and biomarkers as new phosphores. Nanosize semiconductor materials exhibit high emission efficiency when the surface state of the particles is controlled properly. A wide variety of capped nanoparticles have been prepared from metalorganic precursor through solvo-thermal route in presence of various capping agents. However, most of these reactions require the conventional chemicals like dimethyl cadmium and diisopropyl telluride, which are extremely toxic, pyrophoric, and explosive. The use of single-source molecular precursor for the preparation of nanoparticles avoids such potential problems. A convenient solvo-thermal route has been developed for the preparation of cadmium telluride nanoparticles using a novel single source molecular precursor. The X-ray diffraction pattern confirms the face-centered-cubic structure and average diameter of the nanocrystallite is calculated to be 30 nm. SEM image clearly shows the needle-like structure, which is further supported by TEM image where pearl neckless like2 nanoparticles are clearly seen.

53. Silicon Carbide Foam The Defence Materials & Stores Research & Development Establishment (DMSRDE), Kanpur The technology is a meltable and soluble material, which on heating swells forming foam and afterwards pyrolysed to yield desired shape and size silicon carbide foam. The porosity of the foam could be controlled and manipulated up to micron size level. The density and the poly type nature of SiC could also be manipulated depending on the rate of heating and retention time of the material at final temperature. This art of SiC foam is entirely different than international state of art where such foams are prepared using a slurry of course and fine powder of SiC and fixing it to organic foams and on pyrolysis yielded silicon carbide foam.

Syntactic foams of various predefined shapes and densities are available from limited number of sources. However, none of them provide flexibility to form custom shapes and customized densities as per user requirements. Syntactic foams are a special class of low density and high strength materials, which has macro balloons inclusion uniformly in a polymer matrix. Since the material is a liquid casting system, it can be tailored to the varieties of properties and shape over a wide range of densities and strength. The lab has developed syntactic foams formulations based on polyster, epoxy, polyurethane as matrix material and glass, PAN and phenoset micro spheres as fillers material. Syntactic foam formulations having densities varying from 0.2 gm/cc to 1 gm/cc with various rheology, pot life, hydrostatic compressibility, water absorption, and density, compressive and tensile modulus are developed for various applications.

Areas of Application The material has immense underwater applications such as for making floats, buoys, buoyancy modules for sensors, instruments collar, bend restrictors for cables. Also, they can be used as putty and FRP repairing material. It can also be used as a replacement for honeycomb structure in constructions.

55. Through Thickness Permeability Measurement Set up Research and Development Establishment (R&DE), Pune The innovation is a device to measure the in-plane and through-thickness permeabilities of the perform in the Vacuum Assisted Resin Transfer Molding VARTM process in which resin flows under action of vacuum through dry reinforcement. The resin flows over the surface of the reinforcement through the resin distribution medium and through the thickness to wet the volume of the reinforcement perform. Time taken for resin to flow through the preform in-plane and through thickness depends on preform permeability. The present technology will help to know the various permeabilities in advance. The device allows planar flow through thickness of the preform and time for flow is recorded. Darcy's law is employed to determine perform permeability. The innovation claims that this has been successfully tested for different fabric material, architectures, thickness and lay ups and consistent results have been obtained for through thickness permeability. Fabrication of composite structures by resin infusion has evolved over the past decade and has become one of the most promising low cost processes for realization of large high performance structural composites. Vacuum Assisted Resin Transfer Molding (VARTM) process involves flow of resin under action of vacuum into dry reinforcement laid over the mold. This process is ideally suited for manufacture of large composites structures with good structural properties. Since resin flows into dry reinforcement under action of vacuum, permeability of the reinforcement stack is the most crucial parameter for consideration of the process designer. Successful fabrication depends on complete saturation of the reinforcement by resin and process has to be designed to achieve this. Resin Transfer Molding (RTM) process, which uses a hard mold instead of a vacuum bag, also has similar requirement. There is no ready solution available in public literature for permeability measurement. Through-thickness permeability measurement is a most daunting

79

task. The lab has developed methodology for measurement of permeabilities in all three directions and developed a simple set up for measuring through thickness permeability of reinforcement. A patent has been filed for this concept with Indian patent office. This set up has been tested for different fabric material, architectures; thickness and lay-ups and consistent results have been obtained for through thickness permeability. Measured permeability values are regularly used in process simulation for realization of large composites structures. The setup has following features: 1. No limit on the thickness of lay up. Thus the same set up can used for a wide range of thickness of lay ups. 2. No presence of any intrusive sensor 3. No requirement of any expensive post processing system 4. Very compact set up and easy to handle

Areas of Application VARTM process pioneered by boat manufacturers, is extensively used by wind turbine rotor blade manufacturers. It is also finding extensive application in transportation sector, automotive industry and civil infrastructure rehabilitation industry. Anyone using VARTM process would find use of the process-monitoring device.

56. Ultrasonic Fuel Guage

Naval Physical & Oceanographic Laboratory (NPOL), Cochin Fuel gauges find versatile application in the industry. In Ultrasonic Fuel Guage, the property of an acoustic wave getting reflected at the fuel-air boundary as echo and capturing/ processing the echo to obtain the travel time information is used to determine the height of the fuel in fuel tank. From height of the fuel in the tank, the volume of the fuel in the fuel tank at any instant of time is derived. An ultrasonic transducer acts as an acoustic wave transmitter as well as a receiver. A narrow pulse of ultrasonic energy is injected into the fuel tank by means of the transducer. The pulse travels through the fuel, gets reflected at the at the fuel-air boundary and reaches back the same tranducer after a time delay, which is propotional to the height of the fuel. The major advantages of Ultrasonic Fuel guage are the reliability, accuracy and precision in any environment and fluctuating temperatures

Areas of Applications: It has a wide range of applications. It can be used for gauging the volume of any liquid in containers. Guage can engineered for use in any environment and a wide range of temperatures. Can be used for static as well as dynamic conditions in: a) Transport vehicles air, rail, sea or road transport b) Industrial equipments

58. Liquid spring based Shock Absorption System (SAS) Research and Development Establishment (R&DE), Pune The innovation is a compact designed Shock Isolator based on Liquid Spring based Shock Absorption System mainly meant for automotive applications to reduce/eliminate the jerking effect. It works on principles of hydraulic piston and cylinder having holes on piston. Very high shock (in general term jerk) can be absorbed/isolated and accepted shock level can be imparted to the system mounted on it. In technical term, fluid inside the Liquid spring plays the role of Spring and holes on piston plays the role of damper. Compare to conventional SAS (isolator), its size can be almost 4-5 times less and it can be designed and developed for the restricted space. The relative size of the Liquid Spring is very small compared to conventional shock absorbers and hence it can be successfully and efficiently utilized in a comparatively smaller space, thus leaving more space that can be utilized by the other devices, if required. Other possible areas of applications include, Aircraft Landing Gear, Civil Structure prone to earthquake zone. Liquid Spring based SAS is different from the conventional shock absorption system (generally known as suspension is automobile field). It works on principles of hydraulic piston and cylinder having holes on piston. Very high shock (in general term jerk) will be absorbed/isolated and accepted shock level can be imparted to the system mounted on it.
