[B] Institute of Nano Science and Technology (INST), Mohali
[C] Indian Institute of Technology, Delhi
[D] Bhabha Atomic Research Centre (BARC)
Show Answer
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.

Correct Answer: D [Jainism]
Notes:
Santhara, also known as Sallekhana, Pandit-maran, or Sakham-maran, is a Jain religious ritual in which a person voluntarily ends their life through fasting. It has been practised since the origin of Jainism and is mentioned in Jain scriptures called agams. There are two main types: Trivihar, where the person gives up food but not water, and Chauvihar, where both food and water are given up. According to Jain belief, Santhara is followed when death is near or religious duties cannot be performed due to age, illness, or extreme hardship. In 2015, Rajasthan High Court declared Santhara illegal, calling it suicide under Section 306 of the Indian Penal Code (IPC), but this decision was later stayed by the Supreme Court (SC). The practice has recently come back into news, drawing attention to its religious, ethical, and legal aspects.
