Part of Physics (Single Science) Unit 1: Atomic and nuclear physics Most of the mass and all of the positive charge of an atom is in the nucleus. Most of an atom is empty space, (a vacuum). In 1897, ...
Ever since the nucleus of the atom was discovered in 1911, scientists have split, fused and smashed nuclei together to unravel its internal structure. Among the numerous researchers worldwide who are ...

A computational model of the more than 26 million atoms in a DNA-packed viral capsid expands our understanding of virus structure and DNA dynamics, insights that could provide new research avenues and ...
The positions of all the atoms in a sample of a metallic glass have been measured experimentally — fulfilling a decades-old dream for glass scientists, and raising the prospect of fresh insight into ...
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 ...
The discovery shows an efficiency rate that is up to 25 times higher than traditional catalysts made from larger iridium structures or nanoparticles. Catalysts are materials widely used in industry to ...
A collaborative effort between researchers at the Stanford Synchrotron Radiation Lightsource (SSRL) and the University of California, Davis has resulted in the development of a novel methodology for ...
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 ...
