[D] Bhabha Atomic Research Centre (BARC)
[B] Institute of Nano Science and Technology (INST), Mohali
[C] Indian Institute of Technology, Delhi
[D] Bhabha Atomic Research Centre (BARC)
Correct Answer: B [Institute of Nano Science and Technology (INST), Mohali]
Notes:
Researchers at the Institute of Nano Science and Technology (INST), Mohali, have found a new way to improve green hydrogen production. They created a special heterostructure using Copper Tungsten Oxide and Copper Oxide. This structure uses the Built-In Electric Field (BIEF) effect to boost the Hydrogen Evolution Reaction (HER). The Copper Tungsten Oxide nanoparticles are grown over a Cu(OH)₂ base, forming a p-n heterojunction with an uneven electronic setup. This BIEF helps in better proton adsorption and desorption. Green hydrogen, made from water using clean energy, is a pollution-free fuel of the future.

Scientists are closely watching the Axial Seamount as it is expected to erupt for the first time in ten years. Axial Seamount is an underwater shield volcano located about 300 miles off the coast of Oregon, United States, in the Pacific Ocean. It has a large caldera at its summit and rises to a depth of 1,400 meters below sea level. The volcano was formed by a hot spot, where molten material from Earth’s mantle rises into the crust. It lies on the Juan de Fuca Ridge, the tectonic boundary between the Pacific and Juan de Fuca plates. It features hydrothermal vents, which are underwater hot springs that release mineral-rich plumes heated by magma.
