In the absence of air, microorganisms produce hydrogen using an enzyme called [FeFe]-hydrogenase, one of the most efficient hydrogen-producing biocatalysts known and a promising tool for green hydrogen energy. However, these enzymes are rapidly destroyed when exposed to air, which has so far limited their industrial use. Joint efforts led by scientists from the Photobiotechnology group and the Center for Theoretical Chemistry at Ruhr University Bochum, Germany, isolated a new type of oxygen-stable [FeFe]-hydrogenase and revealed its “tricks” for this oxygen-stability. The results are published in “Journal of American Chemical Society” on April 23, 2025.

A research team led by POSTECH Professor Hyung Joo Lee found that NO₂ exposure levels were consistently higher in areas with higher socioeconomic status—an outcome shaped by South Korea’s distinctive history of rapid economic development and urban planning.

KAIST researchers have developed an innovative photodetector capable of detecting a broad range of mid-infrared spectra, garnering significant attention.

- Over 30% faster than all previously known substances

- Development patent pending

- Completely new class of substances discovered

Solid-state batteries are considered a key technology for the future: they can store more energy and do not rely on flammable materials like current lithium-ion batteries. Researchers at TUM and TUMint.Energy Research have now taken a significant step towards improving solid-state batteries. They developed a new material made of lithium, antimony and scandium that conducts lithium ions more than 30% faster than any previously known material.

Researchers have developed two unique energy-efficient and cost-effective systems that use urea found in urine and wastewater to generate hydrogen.

The unique systems reveal new pathways to economically generate ‘green’ hydrogen, a sustainable and renewable energy source, and the potential to remediate nitrogenous waste in aquatic environments.
