Photo: Niels Bohr's research notes for his new atomic theory Rutherford's find came from a very strange experience. Everyone at that time imagined the atom as a "plum pudding." That is, it was roughly ...

What is Atom Probe Tomography? Atom Probe Tomography (APT) is a powerful analytical technique that provides three-dimensional (3D) imaging and chemical composition analysis of materials at the atomic ...

NMAH copy purchased with funds from the S. Dillon Ripley Endowment. This comprehensive scientific history presents for the first time a detailed and comprehensive study of the Bohr atom in all its ...

Researchers at the California NanoSystems Institute at UCLA published a step-by-step framework for determining the ...

Researchers used experiments and machine learning to accurately model the disordered atomic structure of amorphous aluminum oxide for the first time. A special feature of aluminum oxide is its ability ...

Researchers have discovered how to design and place single-photon sources at the atomic scale inside ultrathin 2D materials, lighting the path for future quantum innovations. Like perfectly controlled ...

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 ...

New computer simulations that model every atom of a protein as it folds into its final three-dimensional form support the existence of a recently identified type of protein misfolding. Proteins must ...
