Heavy dipnictogen chemistry: researchers create heterocycles with multiple antimony atoms
Credit: Journal of the American Chemical Society (2025). DOI: 10.1021/jacs.4c15626 An international team of chemists has successfully created methylenedistibirane, a three-membered ring with two antimony atoms and one carbon atom. In a paper published in the Journal of the American Chemical Society, the group describes how they were able to create the rings using just a three-step process. Methylenedistibilane is…

Microplastics found in multiple human organ tissues correlate with pathologies
Graphical summary. Credit: TrAC Trends in Analytical Chemistry (2024). DOI: 10.1016/j.trac.2024.118114 A study led by China’s Zhejiang Agriculture and Forestry University conducted a metadata survey on the presence of microplastics in humans. They report a worrying relationship between micro- and nanoplastic (MNP) concentrations in injured tissues and associations with multiple health conditions. Plastic usage has skyrocketed from 1.5 million tons…
