Electron diffraction is a powerful analytical technique used to study the atomic structure of materials. It involves the interaction of a beam of electrons with a crystalline sample, resulting in a ...

Helium atoms produced soft X-rays far beyond the energy limit expected from the usual one-electron model of high-harmonic ...

Ultrafast electron microscopy (UEM) and ultrafast electron diffraction (UED) employ extremely short electron pulses—ranging from picoseconds down to a few femtoseconds—to image and diffract samples ...

During chemical reactions, atoms in the reacting substances break their bonds and re-arrange, forming different chemical products. This process entails the movement of both electrons (i.e., negatively ...

Back in 2010, crystallographer Tim Gruene heard a scientist from drugmaker Novartis say something that stuck with him. The pharmaceutical giant had amassed a collection of around 2 million small ...

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 ...

What is Auger Electron Spectroscopy (AES)? Analyzing the features of various types of substrates involves the application of the essential analytical technique known as Auger Electron Spectroscopy ...

An instrument that uses high-energy electrons to take "snapshots" of ultrafast chemical processes at the atomic and molecular level just got a major upgrade. Researchers have conducted the first ...

Visual demonstration of the performance of the diffraction grating. The zeroth order transmission refers to light that goes straight through the grating without undergoing diffraction (which should be ...
