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.

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.
