Using photoelectrochemical (PEC) water splitting to produce green hydrogen from solar energy is a potentially practical approach. Unfortunately, the slow water oxidation reaction and very low charge ...

Photoelectrochemical (PEC) water splitting is a potentially feasible strategy for converting solar energy to green hydrogen. However, current PEC systems suffer from relatively low charge separation ...

In the realm of environmental engineering and material science, Professor Kangwoo Cho's team at POSTECH has made notable progress in advancing decentralized saline wastewater treatment and hydrogen ...

The Nature Index 2025 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their output in ...

Researchers develop an economic and energy-efficient nanomaterial that can degrade formaldehyde using UV light Indoor air pollution poses serious health risks due to contaminants like formaldehyde.

Researchers demonstrate the first transparent solar cell. Their innovative technique rests on a specific part of the solar cell: the heterojunction, made up of thin films of materials responsible for ...

Heterojunctions are interfaces formed between two dissimilar semiconductor materials with different band gaps, electron affinities, or work functions. These nanoscale junctions play a crucial role in ...
