The Korea Research Institute of Standards and Science (KRISS, President Lee Ho Seong) has developed a next-generation gas sensor technology that uses low-cost and safe LED light to precisely distinguish multiple hazardous gases. Compared with conventional sensors that operate at high temperatures, the new technology consumes significantly less power, offering greater cost efficiency while delivering broad applicability. It is expected to enhance gas safety across industrial settings as well as everyday environments.

Researchers in Japan developed a high-efficiency iron-based photocatalyst as a cheaper alternative to rare metals like ruthenium and iridium. This catalyst works with blue LED light, significantly reduces the use of chiral ligands, and enables the first synthesis of both enantiomers of heitziamide A, a natural medicine compound that suppresses respiratory bursts.
