Using short laser pulses, researchers have imaged the exact moment an ammonia molecule bends and sheds a hydrogen atom.

Nearly a century ago, Ernst Ruska and Max Knoll provided the first demonstration of a microscope that could image specimens using electrons rather than light. The earliest images obtained via this ...

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

A new framework for understanding the nonmonotonic temperature dependence and sign reversal of the chirality-related ...
