Excited quantum states in nature are normally extremely short-lived, and this certainly applies to most nuclei. But what makes the metastable nuclear states different? And how can we exploit them for ...

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 ...

Isomers of a given compound maintain the same chemical formula, but the unique arrangement of their constituent atoms can cause them to behave very differently. For example, one isomer of ...

BUFFALO, N.Y. — 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, ...
