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

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

The electron diffraction pattern from iodine molecules depends on the distance between the two iodine nuclei, and changes as the molecule vibrates. Disclaimer: AAAS and EurekAlert! are not responsible ...

Pattern indexing is central to electron backscatter diffraction (EBSD) analysis. Creating an effective indexing algorithm was essential in the effort to automate EBSD. There are two steps to ...

MARK, Motz and Trillat 1 have shown that traces of grease can give rise to extra rings in electron diffraction patterns from metal films. In agreement with them, we have found that the spacings of ...

Figure 2: Schematic representation of TMD growth progress over time using the Hypotaxy method. Figure 3: (From top to bottom) Schematic representation of TMD growth progress over time, transmission ...

This article has been updated in January 2024. High resolution images of microscopic samples can be obtained experimentally using Scanning Electron Transmission Microscopy (STEM). It is an effective ...

Schematic of the set-up of the transmission electron microscope. A picosecond pump laser initiates the eutectic reaction in the sample. After a certain time delay, a nanosecond ultraviolet laser pulse ...

In geology, electron backscatter diffraction (EBSD) is a powerful tool for the observation and analysis of microstructures and for phase identification. The EBSD system, by Oxford Instruments, ...

Could you start by explaining your background in crystallography and how you began using the Rigaku Synergy-ED system? Fraser: I began my journey into crystallography at the University of Edinburgh in ...
