Chemical ionization mass spectrometers accurately evaluate VOCs in a wide range of environments. The analysis becomes ambiguous when a compound is obscured by either isomeric or isobaric interference.

Converting a mixture of mirror-image forms, or stereoisomers, of a molecule into a single isomer is a big deal in making pharmaceuticals, because usually only one isomer is useful as a drug. But ...

One hundred years after “nuclear isomers” were first discovered, Philip Walker and Zsolt Podolyák pick five examples of these long-lived, excited nuclear states to show why they are so important in ...

A "dark" environment was created at the Radioactive Ion Beam Line in Lanzhou (RIBLL), China, to look for a faint flash of light as evidence of isomer depletion. Such depletion is required to harness ...

When University at Buffalo chemists analyzed samples of water, fish, and bird eggs, they weren't surprised to find plenty of per- and polyfluoroalkyl substances (PFAS). After all, these "forever ...

The research that could, perhaps, lead to nuclear isomer bombs one day remains contentious in America; the weight of the physics establishment says the science is unproven, even unlikely. But what is ...
