Manufacturing processes

of the Special Lecture: For more than a decade, cooperation between the United States and Indian science and engineering communities has pushed forward the frontiers of discovery and innovation. From materials research and sustainable urban systems to space technology and beyond, various engineering research areas have benefited from this collaboration. Formal mechanisms for cooperation, which have existed for nearly 20 years, coupled with National Science Foundation (NSF) investments in a wide range of research with Indian scientists and institutions, have facilitated numerous accomplishments and discoveries. Dr. Panchanathan will outline the state of scientific and engineering collaboration between the United States and India while also elaborating on his vision for the future of NSF. This includes the importance of ensuring accessibility and inclusivity in STEM fields across the United States and India and advancing technological progress through the continued translation of curiosity-driven, discovery-based research. Building on the firm foundation of past US-India science and engineering engagements, Dr. Panchanathan will discuss strengthening existing engagements and creating new opportunities for collaboration to accelerate discovery and innovation at speed and scale. Abstract of the Lecture: Many or most connected devices - like smart watches, smart locks, location trackers, medical monitors - require long battery life. Since battery technology is not growing at the same pace as the volume of data transferred between devices, innovative methods and techniques to improve energy efficiency have become critical. The question of energy consumed is important in all activities of IoT devices including sense/control, compute, intelligence and communication. This talk covers the current practices in fundamental HW/SW architectural considerations, and algorithmic methods for achieving a very low power wireless end node ASIC design without sacrificing performance. Areas of focus such as HW/SW partition, algorithms, energy efficient wireless receiver algorithms, sleep states, and dynamic performance scaling will be drilled down to explain practical challenges faced in design of wireless SoCs. The talk includes how battery life enhancement is a joint endeavour involving semiconductor device construction and control, the simultaneous use of multiple architecture level techniques, and a seamless approach to wireless design involving algorithms, hardware realizations and software control. Development of Ferritic-Martensitic Steels and Fabrication Technologies for (ITER)” The Indian Space Research Organisation (ISRO) recently successfully conducted the third long-duration hot test of the liquid propellant Vikas engine for the Gaganyaan programme, the country's first manned mission to space. The test was done for the core L110 liquid stage of the human rated GSLV MkIII vehicle, as part of the engine qualification requirements for the Gaganyaan programme, the space agency said in a statement. The engine was fired for 240 seconds at the test facility of ISRO Propulsion Complex (IPRC), Mahendragiri, Tamil Nadu, said the statement. The performance of the engine met the test objectives and the engine parameters were closely matching with the predictions during the entire duration of the test, it said. The objective of the Gaganyaan programme is to demonstrate the capability to send humans to low earth orbit onboard an Indian launch vehicle and bring them back to earth. Four Indian astronaut-candidates have already undergone generic space flight training. ISRO's heavy-lift launcher GSLV Mk III has been identified for the mission. The initial target was to launch the human spaceflight before the 75th anniversary of India's independence on August 15, 2022. ISRO is also taking the help of French, Russian and US space agencies in some of the crucial activities and supply of components, sources said. thinner than a human hair -- and embedded them onto nanofibres. The magnesium hydroxide nanosheets respond to changes in pH, which makes them ideal for use as sensors to track healing. Healthy skin is naturally slightly acidic while infected wounds are moderately alkaline. Under UV light, the nanosheets glow brightly in alkaline environments and fade in acidic conditions, indicating the different pH levels that mark the stages of wound healing. The nanosheets are easily integrated onto any biocompatible nanofibre, which means they can then be deposited onto standard cotton bandages. Laboratory tests showed the magnesium hydroxide nanosheets were non-toxic to human cells, while destroying emerging pathogens like drug-resistant golden staph and Candida auris. Truong said the process to make the fluorescent nanosheets was simple to scale for potential mass production." Normally, antimicrobial wound dressings start to lose their performance after a few days, but our studies show these new dressings could last up to seven days," he said. "And because magnesium is so abundant compared to silver, our advanced dressings could be up to 20 times cheaper." The research team is keen to collaborate with clinicians to further progress the technology, through pre-clinical and clinical trials.
