Determining the 3D atomic structures of multi-element nanoparticles in their native liquid environment is crucial to understanding their physicochemical properties. Graphene liquid cell (GLC) TEM ...

Noble metal nanoparticles supported on semiconducting substrates have long been used in heterogeneous catalysis. A central objective in this field is to identify the active sites for catalysis, which ...

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.

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 ...

MIT-led researchers have, for the first time, directly mapped the 3D atomic and polar structure of relaxor ferroelectrics, materials critical to sensors and energy devices. Using multi-slice electron ...

MIT-led researchers have, for the first time, directly mapped the three-dimensional atomic and charge structure of relaxor ferroelectrics, materials used in sensors, ultrasound, and sonar. Using multi ...
