Electron microscopy is a powerful technique that provides high-resolution images by focusing a beam of electrons to reveal fine structural details in biological and material specimens. 2 Because ...

A major discovery is reshaping how scientists think about catalysts. Researchers have, for the first time, captured oxygen atoms moving through the interior of a catalyst—not just along its surface.

Electron microscopy (EM) has become an indispensable tool for investigating the nanoscale structure of a large range of materials, across physical and life sciences. It is vital for characterisation ...

Giant prehistoric insects may not have depended on high oxygen levels after all. Scientists now think something else must ...
