Chemistry textbooks explain how reactions start and end, but they rarely show what happens ...

During chemical reactions, atoms in the reacting substances break their bonds and re-arrange, forming different chemical ...

Our ability to image the subatomic realm is limited, not just by resolution, but also by speed. The constituent particles that make up – and fly free from – atoms can, in theory, move at speeds ...

Scientists used an ultrafast X-ray laser to follow the impact of a single electron moving within a molecule during an entire chemical reaction. (Nanowerk News) Valence electrons, located in the ...

Valence electrons, located in the outermost shell of an atom, play an important role in driving chemical reactions and forming bonds with other atoms. But imaging these particles as they perform this ...

This image depicts the radium atom’s pear-shaped nucleus of protons and neutrons in the center, surrounded by a cloud of electrons (yellow), and an electron (yellow ball with arrow) that has a ...

A new way of imaging frozen biological samples using electron microscopy is providing new glimpses into the nanoscopic world of cells. Images reveal bent in-vitro tubulin microtubules next to and in a ...
