During chemical reactions, atoms in the reacting substances break their bonds and re-arrange, forming different chemical ...

First, the researchers used a short laser pulse about 200 nanometers in wavelength to excite ammonia molecules. This pump ...

Recent advances in electron density analysis and X‐ray diffraction studies have dramatically refined our understanding of atomic and molecular structures. By employing cutting‐edge techniques that ...

For pharmaceuticals, knowing the chemical composition is not enough - molecular geometry and crystal structure also play an important role in a drug's activity. By using a method based on electron ...

What is Electron Backscatter Diffraction (EBSD)? Electron backscatter diffraction (EBSD), also known as backscatter Kikuchi diffraction (BKD), is a powerful characterization technique used to analyze ...

(Nanowerk News) Metal-Organic Frameworks (MOFs) are porous crystalline materials whose structure resembles a scaffold of beams around a large empty space; this internal space can be used to store ...

4D STEM is currently used in many TEM projects and is for sure on every electron microscopist’s “must-watch” list. Recent advancements in TEM technology, particularly the hybrid-pixel direct electron ...

Antiferromagnetic (AF) crystals like NiO are experiencing a renaissance as promising materials for ultrafast spintronics. To re-establish old experimental results of surface property investigations ...

An electron neutrino scattering event from the latest NOvA dataset. The brighter the yellow pixels, the more energy that was deposited. Physicists know this is a neutrino because it occurs in time ...
