Defence Research and Development Organisation (DRDO), on September 13, 2024, successfully conducted the preliminary automotive trials of the Indian light Tank, Zorawar, a highly versatile platform capable of deployment in high-altitude areas. During the field trials conducted in the desert terrain, the Light Tank demonstrated exceptional performance, efficiently meeting all the intended objectives. In the initial phase, the tank’s firing performance was rigorously evaluated and it achieved the required accuracy on designated targets. Zorawar has been successfully developed by the Combat Vehicles Research & Development Establishment (CVRDE), a unit of…

Defence Research & Development Organisation (DRDO) and the Indian Navy have conducted back-to-back successful flight tests of the Vertical Launch Short Range Surface to Air Missile (VLSRSAM). The second consecutive test was conducted on September 13, 2024, from the Integrated Test Range (ITR), Chandipur, Odisha. The missile intercepted a high-speed aerial target, flying at a very low altitude and simulating a sea-skimming threat, which showcased its precision and capability to neutralise targets. This follows the earlier test on September 12, 2024, when the VLSRSAM missile effectively engaged another low-altitude target.…

Scientists have found a low-cost solution called nanosecond laser surface texturing to increase lubrication of the moving parts within the engine can enhance engine performance. Internal combustion (IC) engines represent a backbone of modern transport, with millions of vehicles run worldwide. Still, their efficiency leaves room for improvement. One big challenge to the performance of an IC engine is the friction and wear between moving parts, which causes enormous energy loss and, as a result, low fuel economy. Researchers at the International Advanced Research Centre for Powder Metallurgy & New…

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…
