Solar-powered systems convert waste into ammonia and glycolic acid
Graphical abstract. Credit: Nano Letter (2025). doi:10.1021/acs.nanolett.4c05932 A team of researchers at Unist has developed a new technology that uses solar energy to eliminate carbon dioxide emissions while also producing key components of cosmetics, ammonia and glycolic acid. A team, co-led with Seungho Cho and Professor Myoung Hoon from UNIST’s Faculty of Materials Science and Engineering, Song, has created a…

Acid dissolution of mine waste – a new environmentally friendly way to extract metals
Credit: CC0 Public Domain New research shows that magnesium and other metals in mine waste can be solubilized and recovered thanks to acid-producing bacteria. Researcher Nathan van Wyk believes this method has great potential to reduce environmental pollution, extend the life of mines and provide raw materials for industry. Each year, more than 3 billion tons of metals are produced…

New process strengthens thermoplastic and polylactic acid blends
In nano-IR imaging, the layer structure of the pure PVDF/PLLA mixture (left) and the layer with SAD additive (right) can be clearly distinguished. Light and dark colors correspond to the PLLA and PVDF phases, respectively. Adding SAD reduces the domain size in two phases.
