Using a technique called multi-slice electron ptychography (MEP), researchers move a nanoscale-sized probe of electrons over a material and measure the resulting electron diffraction patterns.

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 ...

AZoNano speaks to Dr. John Miao about his involvement in the breakthrough research that could rewrite our understanding of how substances are formed at an atomic level. Using an innovative atomic ...

Many substances around us, from table salt and sugar to most metals, are arranged into crystals. Because their molecules are laid out in an orderly, repetitive pattern, much is understood about their ...

Researchers at the California NanoSystems Institute at UCLA published a step-by-step framework for determining the three-dimensional positions and elemental identities of atoms in amorphous materials.
