Engineered molecule stashes enough sunlight to boil water months later DNA-inspired pyrimidone sets capacity record for storing solar thermal energy in bonds

A new water-soluble pyrimidone absorbs ultraviolet light and stores energy in its chemical bonds. Adding acid to the solution triggers the molecule to rapidly release enough heat to begin boiling the water.

Replacements for CFCs spread PFAS across the globe A third of trifluoroacetic acid (TFA) pollution is linked to CFC replacement chemicals, study finds

Replacements for CFCs have their own drawbacks: they’re greenhouse gases and break down into short-chain per- and polyfluoroalkyl substances (PFAS) in the atmosphere that spread to every corner of the world.

The chemical industry promises another year of cutbacks Firms cut costs in 2025, but after dismal earnings reports, more of the same is in store

In an environment rife with uncertainty, overcapacity, and sluggish markets, chemical company results plunged in 2025. But as executives disclosed financial results for the year, they argued that their efforts to control their own destinies at least blunted the blows from a hostile market. #chemsky🧪

Can recycled lab gloves capture carbon dioxide? Chemists upcycle nitrile rubber into carbon-sequestering polyamines

As you may have heard we've got both a climate crisis and a plastic waste crisis on our hands. My latest news story for @cenmag.bsky.social is about researchers trying to tackle both problems at once by upcycling nitrile rubber gloves to capture carbon dioxide:
