Per- and polyfluoroalkyl substances (PFAS), known as forever chemicals, were once prized for the strength of their carbon-fluorine bonds. But now a ubiquitous health concern, the tough molecules have made their way into groundwater, soil, and humans across the globe.
Chemical structures embed vast amounts of information that needs translating for machines Learning the language of chemistry Outside of my day-job at Chemistry World, I teach a couple of small-group tutorial classes of first-year chemistry undergraduates. With a new academic…
Covalent organic frameworks could help capture and break down nitrate pollution from waterways that causes algal blooms Covalent organic frameworks (COFs) can be used to rearrange water molecules, increasing the efficiency of the reduction of nitrate to ammonia, researchers in…
Many commercial products, including plasticizers and detergents, rely on aldehyde building blocks. Hydroformylation constructs aldehydes from alkenes and synthesis gas—a mixture of carbon monoxide and hydrogen. The industrial process currently uses rhodium-based catalysts that are expensive, involve toxic phosphine-containing…
In March of last year, 23andMe, one of the world’s leading consumer genetic testing companies, filed for bankruptcy. The company had become a household name after it released the first home-testing kits for ancestry back in 2007. And over time, the capabilities…
Federation: Log in through a federation service that connects your organization to multiple systems. Use this option if your organization instructs you to use federated sign-in. Microplastics might not be as chemically inert as expected Microparticle surfaces produce reactive oxygen…
Conceptual, epistemic and political factors all influence who is deemed to have made a scientific discovery Andrés Manuel del Rio, Johann Wolfgang Döbereiner and Henri Kagan have all been part of separate controversies over scientific credit Every year when the…
Tips to help a wider range of students feel like they belong in chemistry Source: Courtesy of Baljit Thatti Baljit Thatti says chemistry departments should do more to teach the context in which scientists perform research ‘A diverse curriculum is…
Chemists have tracked the fleeting intermediates in the natural synthesis of penicillin using ultrashort x-ray pulses. The research could usher in improvements in ring-forming reactions on useful intermediates for the pharmaceutical industry or aid enzyme engineering. Animated molecular movie of…
