The intermediate range order of covalent glasses has been extensively studied in terms of the first sharp diffraction peak (FSDP), but the direct observation of the atomic density fluctuations that ...

Researchers with the Department of Energy's Oak Ridge National Laboratory and the University of Tennessee, Knoxville, have created an innovative method to visualize and analyze atomic structures ...

Since their discovery in 1982, exotic materials known as quasicrystals have bedeviled physicists and chemists. Their atoms arrange themselves into chains of pentagons, decagons and other shapes to ...

Different atoms and ions possess characteristic energy levels. Like a fingerprint, they are unique for each species. Among ...

In materials science, particularly in the study of glasses, the intermediate range order (IRO) is one of the most intriguing research areas owing to its significant influence over the physical ...

The ability to describe the internal structure of atoms is important not only for understanding the composition of matter, but also for designing new experiments to explore fundamental physics.

At extreme pressures and temperatures, water becomes superionic — a solid that behaves partly like a liquid and conducts ...

Atomic level surface control raised light emission in indium phosphide magic sized clusters from under 1% to 18.1%, ...

Electronics keep shrinking, but silicon is starting to run into physical limits. To go smaller, researchers are turning to something far tinier than any transistor on a chip: single molecules that act ...
