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.

A new project called SeaCURE has begun on the south coast of England to remove carbon dioxide from the sea. The SeaCURE project is an initiative of the United Kingdom (UK) government. The SeaCURE project is testing if taking carbon directly from seawater can be a low-cost and large-scale way to cut down carbon dioxide in the air. This method is different from usual carbon capture techniques that focus on emissions at their source or pull carbon dioxide from the air. SeaCURE targets the ocean, where carbon levels are up to 150 times higher than in the atmosphere.

Archaeological Survey of India (ASI) recently found 11 Satavahana-era inscriptions in the Gundaram Forest of Telangana’s Peddapalli district. Two inscriptions mention the Chutu dynasty and a Satavahana prince named Kumāra Hakusiri. These inscriptions are written in early Brahmi script and show religious and political symbols. The Satavahana dynasty was founded by Simuka after the Mauryan Empire, around mid-1st century BCE. The word “Satavahana” in Prakrit means “driven by seven,” symbolizing the chariot of the Sun God. Their main regions were Andhra Pradesh, Telangana, and Maharashtra. They ruled from capitals like Pratishthana (Paithan) and Amaravati.

It also aims to promote the use of modern agricultural technologies in the state. This decision highlights the government’s focus on controlling pollution and encouraging sustainable farming practices.
