Identifying structural order in Selenium with Near-Edge Spectroscopy [PDF]
arXiv, 2009 We investigate the crystallization of amorphous arsenic-selenium alloys with 0%, 0.5%, 2%, 6%, 10%, and 19% arsenic by atomic concentration using synchrotron X-ray absorption spectroscopy. We identify crystalline order using the extended X-ray absorption fine structure (EXAFS) spectra and correlate this order to changes in features of the X-ray ...

Total energy calculation of high pressure selenium: The origin of incommensurate modulations in Se-IV and the instability of proposed Se-II [PDF]
, 2004 We present calculation of the high pressure crystal structures in selenium, including rational approximants to the recently reported incommensurate phases. We show how the incommensurate phases can be intuitively explained in terms of imaginary phonon frequencies arising from Kohn anomalies in the putative undistorted phase.

Flexible Selenium Nanowires with Tuneable Electronic Bandgaps
Advanced Materials, EarlyView.Nanotubes serve as effective test tubes for selenium nanowires, as their diameter precisely controls the width of the nanowires and the Se─Se bonding, resulting in a variety of different structures. An electron beam can be used to modify the nanotubes, allowing real‐time observation of the nanowire extrusion process. Additionally, optically transparent

Identifying Market Preferences for High Selenium Beef [PDF]
Selenium is an element found in relatively high concentrations in crops and livestock raised on high-selenium soils located in North and South Dakota. Evidence suggests that a high-selenium diet such as would be obtained from consuming these products can

Zinc Chalcogenide Based Shell Layers for Colloidal Quantum Wells
Advanced Materials Interfaces, EarlyView.A new synthetic route is developed for the synthesis of CdSe/ZnSe/ZnS multi‐shell nanoplatelets (NPLs) with emissions between 615 and 630 nm and photoluminescence quantum yields up to 90%. Control over the lateral size of the starting CdSe core enabled the narrowing of the emission linewidth to 20 nm.
