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 ...

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 ...

(a) Schematic of imine bond formation. (b) The building block molecules chosen in this work (R: polyethylene glycol chain) and the construction of an extended network by imine bond formations through ...

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 ...

Samples from water, fish and bird eggs demonstrate the need to measure these unique molecular structures separately.

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.
