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 ...

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 ...

The inside of giant planets can reach pressures more than one million times the Earth's atmosphere. As a result of that intense pressure, materials can adopt unexpected structures and properties.

Crystallography is the science of analyzing the pattern produced by shining an X-ray beam through a material sample. A powder sample produces a different pattern than solid crystal. One longstanding ...

Scientists at the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) have developed a new way to determine atomic structures from nanocrystals previously considered unusable, ...

(Nanowerk Spotlight) At the scale of individual atoms, materials behave in ways that defy everyday intuition. Stretch a metal wire by a few micrometers and its resistance changes only slightly.

Generally chemical synthesis involves putting a variety of compounds together in an environment where they will react and self-assemble into the desired product. You could also imagine simply putting ...

Antiferromagnetic materials, with antiparallel atomic spins and zero net magnetization, are fast and resistant to external magnetic interference, making them ideal for high-speed, high-density ...

Aaron Rossini of Iowa State and Ames National Laboratory with the nuclear magnetic resonance instrument in his lab. AMES, Iowa – A tiny, solid sample of a drug, complete with active and inactive ...

Chemists have developed an efficient skeletal editing method for frequently used heteroaromatic structures. The technique could serve as a means to chemically modify biologically active compounds.
