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

No chemical reaction or energy transfer process can take place without electrons, as they are responsible for forming and breaking chemical bonds. Therefore, to control and manipulate chemical ...

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

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 ...

The UK’s first dedicated electron diffraction center is due to open in the Summer of 2023. The new facility will help UK nanoscientists to characterize the "tiniest of crystals", according to Derek ...

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 ...

Researchers already knew the atoms in perovskites react favorably to light. Now they've seen precisely how the atoms move when the 2D materials are excited with light. Their study details the first ...

For the experiment, an intense femtosecond ultraviolet laser pulse was employed to induce resonance-enhanced multiphoton ionization in 1,3-dibromopropane (1,3-DBP) molecules. The picosecond and ...
