Scientists from Raman Research Institute, an autonomous institute of the Department of Science & Technology, Govt. of India, have found that by changing the viscosity of the displacing fluid and the concentration-dependent elasticity of the displaced fluid, the instability can be reduced and the roughness of the interfacial pattern and the efficiency of displacement can be controlled.

Secretary DDR&D and Chairman DRDO Dr G Satheesh Reddy has been conferred the prestigious Aryabhata Award by the Astronautical Society of India (ASI) for his outstanding lifetime contribution to the promotion of astronautics in India.

The team has used DST FIST-supported High-temperature X-ray diffraction (HTXRD) facility Rigaku SmartLab, particularly useful for the thermal stability assessment of novel solid electrolytes. The XRD patterns were obtained in situ up to 500 oC. Now, the batteries and supercapacitors to operate at high temperatures are being developed.

Defence PSU Hindustan Aeronautics Limited (HAL) on Thursday said that the heaviest semi-cryogenic propellant tank (SC120- LOX) it has ever fabricated has been delivered to Indian Space Research Organization (Isro).

The chickpea varieties, IPC L4-14, BGM 4005 and IPCMB 19-3, have been developed in collaborations with ICAR-Indian Institute of Pulses Research (IIPR), Kanpur, and ICAR-Indian Agricultural Research Institute (IARI), New Delhi.

A team of Indian scientists have developed an environmentally friendly, non-toxic, biodegradable polymer using guar gum and chitosan, both of which are polysaccharides extracted from guar beans and shells of crab and shrimps. The fabricated guar gum-chitosan film having high water stability, high mechanical strength, and excellent resistance to harsh environmental conditions can potentially be used in packaging applications.

Indian researchers have developed a method that can help large scale synthesis of a special class of semiconductor nanocrystals. These nanocrystals called two-dimensional layered perovskite and perovskite nanocrystals, which have bright emission colours and are not affected by or corroded by the environment, are useful for both high colour purity and low-cost solution processability.

While two of them — EOS-4 (Risat-1A) and EOS-6 (Oceansat-3) — will be launched using Isro’s workhorse PSLV, the third one, EOS-2 (Microsat), will be launched in the first developmental flight of the Small Satellite Launch Vehicle (SSLV), marking the beginning of a new class of launch vehicles in India.

Indian Scientists have developed a novel high-performance bioreactor system integrated with sustainable pre-treatment process for enabling anaerobic digestion of complex fat-rich sludge from dairy industry. It has been further integrated with membrane bioreactor based-wastewater treatment to enable zero liquid discharge in the dairy industry.

ISRO’s first mission dedicated for astronomy, AstroSat, launched on 28 September 2015 with its design life of five years, on Tuesday completed six years of its operation. “It (AstroSat) is expected to last some more years”, A S Kiran Kumar who as the then Chairman of ISRO led the mission team, and is presently serving as the chair of the apex science committee at the space agency, told PTI. “We can expect some more results to come which will be path-breaking”, he said.
