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, ...
Researchers with the Department of Energy's Oak Ridge National Laboratory and the University of Tennessee, Knoxville, have ...
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 ...
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 ...
Bohr’s Model of an Atom: Danish Physicist Niels Bohr received his Ph.D. from the University of Copenhagen in 1911. In 1922, he was awarded the Nobel Prize in Physics for his work on the atom’s ...
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 ...
What you’re looking at is the first direct observation of an atom’s electron orbital — an atom’s actual wave function! To capture the image, researchers utilized a new quantum microscope — an ...
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 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 ...
