News on Science, Technology and Research in India
Researchers at Indian Institute of Technology (IIT) Madras have successfully developed a white light emitter for use in LEDs. The development of energy-efficient Light Emitting Diodes or LEDs replaced the energy-inefficient incandescent lamps in lighting and display applications. While LEDs have been available in almost all colours, white LEDs are a more recent development.
The research, published in the journal GCB Bioenergy, estimated the break-even price and life cycle carbon emissions of the sustainable aviation fuel (SAF) derived from oil obtained from Brassica carinata, a non-edible oilseed crop.
Astronomers exploring regions on the Sun with disturbed magnetic fields or active regions that sometimes exhibitsolar flares without accompanying Coronal Mass Ejection (CME) have confirmed that changing structure of the magnetic field on the Sun’s surface determined whether a flare or a CME was emitted. This understanding will be useful in improving predictions of solar weather, which can affect electrical, and communication systems in Earth and satellite systems in space.
“Traditional warning systems are based on the fixed speed threshold, however, the concept of a smart warning system is based on upcoming road infrastructure and vehicle location. On approaching curves along a roadway, including blind curves or hairpin bends, vehicles equipped with such a system will warn drivers in advance, which will allow drivers to adopt corrective actions and avoid accidents,” he added.
A team of scientists have used tea and banana waste to prepare non-toxic activated carbon, which is useful for several purposes like industrial pollution control, water purification, food and beverage processing, and odour removal. The newly developed process avoids usage of any toxic agent for synthesizing activated carbon, thus making the product cost-effective as well as non-toxic.
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.
