News Contaminants

  • Chemistry discovery could remove micropollutants from environment

    Using a pioneering imaging technique, Cornell University researchers obtained a high-resolution snapshot of how ligands, molecules that bind to other molecules or metals, interact with the surface of nanoparticles. In doing so, they made an unexpected breakthrough discovery. They determined that by more

  • Wastewater Treatment Using Sunlight

    Chemists at the Leibniz Institute for Catalysis in Rostock discovered the molecular mechanism of a photocatalyst that completely breaks down organic contaminants in wastewater with the help of sunlight. Worldwide, for example, more and more residues of drugs such as anti-inflammatory drugs, antibiot more

  • Trapping of Acetylene

    Ethylene, a key feedstock in the chemical industry, often includes traces of acetylene contaminants, which need to be removed. In the journal Angewandte Chemie, researchers describe a robust and regenerable porous metal–organic framework that captures acetylene with extraordinary efficiency and sele more
