Defence Research & Development Organisation (DRDO) and the Indian Navy successfully conducted the flight test of the Vertical Launch Short Range Surface-to-Air Missile (VL-SRSAM) from the Integrated Test Range (ITR) in Chandipur, off the coast of Odisha, on September 12, 2024, at approximately 1500 hours. The flight test was carried out from a land-based vertical launcher, targeting a high-speed aerial target flying at a low altitude. The missile system successfully tracked and engaged the target. This test aimed to validate multiple updated elements of the weapon system, including the Proximity…

In a magnetic material, a paramagnetic phase, in which the material shows weaker temporary attraction when exposed to a magnetic field, is attained at a temperature higher than the ferromagnetic phase.  Surprizingly, the hotter paramagnets, even by travelling longer distances, thermodynamically, undergo faster transitions to their ferromagnetic phases, shows a new study. The research which establishes a phenomenon called Mpemba effect, earlier found in water, to be existing in magnets too, can bring a new perspective to thermal control in devices. Mpemba effect is a paradoxical phenomenon in which a…

A new method of introducing controlled defects in MOF-Based super capacitors through laser irradiation, can help enhance performance of existing energy storage technologies. In recent years, several methods have been investigated for creating defects, such as thermal annealing, chemical exposure, high-energy ball milling, e-beam, chemical vapor deposition. However, the extent of defects could not be controlled in the materials using these methods. Traditional methods lack the precision needed for fine-tuning of defects. In order to enhance the activity of the pristine MOF (Metal Organic Framework) without transforming it into other…
