Jupiter's 'Trojans' on an atomic scale (1/27/2012)

The Bohr Model describes the atom as a nucleus circled by electrons, much like a star circled by planets -- but quantum theory taught us that particles do not travel on well-defined trajectories but behave as a quantum wave. Now scientists succeeded in preparing atoms which indeed behave like a miniature version of a solar system. ...> Full Article

'Fingerprints' match molecular simulations with reality (2/24/2011)

A theoretical technique developed at the Department of Energy's Oak Ridge National Laboratory is bringing supercomputer simulations and experimental results closer together by identifying common "fingerprints." ...> Full Article

Physicists take new look at the atom (2/1/2011)

UA physicists have discovered a new way to measure how single atoms interact with a surface. Their findings help develop nanotechnology and test new theories about the internal structure of atoms. ...> Full Article

Researchers holding steady in an atomic-scale tug-of-war (4/6/2010)

A NIST team has built an ultra-stable instrument for tugging on chains of atoms, an instrument that can maneuver and hold the position of an atomic probe to within 5 picometers. ...> Full Article

Z-contrast microscope first to resolve, identify individual light atoms (3/30/2010)

Using the latest in aberration-corrected electron microscopy, researchers at the Department of Energy's Oak Ridge National Laboratory and their colleagues have obtained the first images that distinguish individual light atoms such as boron, carbon, nitrogen and oxygen. ...> Full Article

Physicists turn to radio dial for finer atomic matchmaking (10/24/2009)

Investigating mysterious data in ultracold gases of rubidium atoms, scientists at the Joint Quantum Institute of the National Institute of Standards and Technology and the University of Maryland and their collaborators have found that properly tuned radio-frequency waves can influence how much the atoms attract or repel one another, opening up new ways to control their interactions. ...> Full Article

Super atoms turn the periodic table upside down (7/2/2008)

Researchers have developed a technique for generating atom clusters made from silver and other metals. Surprisingly enough, these so-called super atoms (clusters of 13 silver atoms, for example) behave in the same way as individual atoms and have opened up a whole new branch of chemistry ...> Full Article

Protons partner with neutrons more often than other protons (6/19/2008)

Fast-moving protons are much more likely to pair up with fast-moving neutrons than with other protons in the nuclei of atoms ...> Full Article

By color-coding atoms, new electron microscope promises big advance in materials analysis (2/26/2008)

A new electron microscope recently installed in Cornell's Duffield Hall is enabling scientists for the first time to form images that uniquely identify individual atoms in a crystal and see how those atoms bond to one another. And in living color. ...> Full Article

New Experimental Atomic Clock Surpasses Accuracy Of Current U.S. Standard Time Clock (2/15/2008)

A next-generation atomic clock developed by researchers from the National Institute of Standards and Technology and the University of Colorado at Boulder has been shown to be accurate to within one second over 200 million years, surpassing the accuracy of the current U.S. time standard atomic clock more than two-fold. ...> Full Article
