In fact, 99.999% of an atom is void, making their structure hard to grasp. Electrons don’t follow fixed paths, they behave like waves, forming probability “clouds” around the nucleus.

Studying the production mechanisms, internal structure, and de-excitation properties of these excited-state atoms provides insights into quantum electrodynamics and quantum many-body interactions ...

The first atom-level model of a DNA-packed viral capsid reveals genome structure and possible new drug targets, University of Illinois researchers report. Pictured, from left: physics professor ...

For nearly two centuries, morphine derivatives like codeine, heroin, and naloxone were developed by making peripheral modifications to the molecule's structure and not the core E-ring oxygen atom.
