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 ...

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 ...

(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.

Students use the terms isotope, atomic number, mass number, and atomic mass. Atomic Theory: Structure of the Atom: Students use the terms isotope, atomic number, mass number, and atomic mass to ...

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 shapes of atomic orbitals also affect the spectroscopic properties of atoms and molecules. The absorption and emission of ...

The inside of giant planets can reach pressures more than one million times the Earth's atmosphere. As a result of that ...

Researchers’ new method that delivers more control over halide perovskites could transform how solar cells, LEDs and lasers ...

In this video excerpt from NOVA's "Hunting the Elements," New York Times technology columnist David Pogue visits The Verdin Company, a manufacturer of bells, to learn about bronze. Find out how copper ...

An artificial intelligence that can predict how a piece of glass responds to heat and pressure could one day also be used to model traffic flow. While most solid materials have a regular atomic ...
