Development of an x-ray excited optical luminescence microscope (XEOM) [PDF]

X-ray excited optical luminescence (XEOL) refers to the trans-visible emission produced as a consequence of X-ray bombardment and provides an alternative detection method for X-ray absorption spectroscopy (XAS). Whereas XAS measured by conventional means

High resolution silicon drift detector array designed for XAFS spectroscopy [PDF]

, 1997
We have analyzed the performances of an array of 6 silicon drift detectors with on chip integrated JFET's for XAFS spectroscopy. The key advantage of these detectors is that they combine a very good energy resolution together with high counting rates: at

Determination of Chromium(VI) Reduction by Acinetobacter haemolyticus using X-ray Absorption Fine Structure Spectroscopy [PDF]

, 2014
Several types of microorganisms have been reported to reduce Cr(VI) to the less toxic Cr(III) via enzymatic reactions. The main purpose of this study is to determine the reduction of Cr(VI) by a locally isolated bacterium, Acinetobacter haemolyticus (A ...

Effects of Cs/Sr intercalation on the structure and electrical conductivity of weathered biotite [PDF]

AIP Advances
Weathered biotite (WB) is a layered clay mineral composed of Si, Al, Fe, and Mg. After molten-salt treatment at temperatures above 700 °C, WB exhibits thermoelectric properties, making it a low-cost and thermally robust candidate for sustainable high ...
