Fiber catalysts are easy to handle and free of mass-transfer resistance. This report is the first application of cloth catalysts to water denitrification. In this work, cloths woven from glass fibers (GF) of 7–10 mm in diameter, impregnated with Pd, were t ...
X-ray microanalysis was employed to screen biogenic plant silica extracted from the aboveground tissues of 20 species (Grammeae Cyperaceae. Ericaceae, and Coniferae) occurring in subalpine and alpine grasslands, heaths, and woodlands on siliceous bedrock i ...
The implantation of Ni ions into pure Al leads to the formation of similar to 10 nm amorphous zones (AZ) which induce diffuse rings in the diffraction pattern in addition to the diffraction spots of the crystal. Measurements by energy dispersive spectromet ...
Spatially resolved x-ray secondary electron photoemission spectra revealed lateral changes in quantum efficiency and chemical composition of polycrystalline cesium iodide photodetectors. Such changes depend on the substrate (stainless steel or aluminum). T ...
We investigated the interdiffusion of InGaAs/InP quantum wells (QWs) due to rapid thermal annealing (RTA) by photoluminescence (PL) spectroscopy and wedge transmission electron microscopy (WTEM). After RTA at temperatures between 650 and 900 degrees C (ann ...
As other monosaccharide mimics such as the azasugars and the carbasugars (with nitrogen and carbon atom, respectively, instead of oxygen atom in the ring) the thiosugars (with sulfur atom instead of oxygen atom in the ring) have gained importance in glycob ...
Using (secondary) photoelectron emission microscopy, we studied the fully formed 80 Angstrom Pt/n-GaP(001) interface with a lateral resolution better than 2 mu m. We probed the chemically etched and sulfur passivated GaP(001) surface by ultraviolet and sof ...
We present recent results of the study of surface properties and quantum efficiency (QE) of CsI photocathodes prepared on various substrates. Microanalysis methods provide laterally resolved surface morphology and chemical composition of the photoemissive ...
SnO2 thin films have been grown by radio frequency reactive sputtering method in order to be used as a gas sensor. Subsequently Pt has been added to the SnO2 films to increase the sensitivity to carbon monoxide gas. Two different substrates have been used: ...
The microstructure and chemical composition of sputtered thin films are strongly correlated with the deposition conditions. In the present work, we report the investigation of the film composition by electron probe microanalysis and photoemission experimen ...
