The Bohr model, introduced by Danish physicist Niels Bohr in 1913, was a key step on the journey to understand atoms. Ancient Greek thinkers already believed that matter was composed of tiny basic ...

(Nanowerk News) Molecules are so small that we cannot even see them with ordinary microscopes. This makes studying molecules or chemical reactions difficult: researchers are limited to either indirect ...

Nearly all computer models of molecules and materials are based on density functional theory (DFT) approximations. These methods help efficiently simulate the structure, energy, and properties of ...

New insights into a popular and potentially useful model of how electrons behave in solids have been provided by an experiment involving ultracold atoms. Markus Greiner and colleagues at Harvard ...

Starlight and stardust are not enough to drive the powerful winds of giant stars, transporting the building blocks of life ...

An international group of researchers, working on complex computer models for predicting the behavior of electrons, has discovered that those very computational models might not be as accurate as they ...
