Sulfur in different chemical surroundings – S K XANES spectra of sulfur-containing heterocycles and their quantum-chemically supported interpretation

Investigation of different human pathogenic and food contaminating bacteria and moulds grown on selenite/selenate and tellurite/tellurate by X-ray absorption spectroscopy

“…1(b) and (c)). Similar behaviour was reported in literature previously and partly also supported by theoretical calculations (Chauvistré et al, 1997;Flemmig et al, 2001;Mochizuki, Agren, Petterson, & Carravetta, 1999;Vairavamurthy, 1998;Von Busch, Hormes, Modrow, & Nestmann, 2003), e.g. with respect to the K-edge XANES spectra of sulphur, which has a valence shell which is iso-electronic to selenium.…”

The Catalytic Conversion of Thiophenes over Large H‐ZSM‐5 Crystals: An X‐Ray, UV/Vis, and Fluorescence Microspectroscopic Study

“…The apparent broadening of the sulfur main edge could also not be explained by the presence of sulfoxide species (RÀS(=O)ÀR'), since the sulfoxide edge appears at much higher energy, that is, 2476 eV. On the other hand, the strong feature at 2470 eV can be assigned to photoreduction products, based on results by Bohic et al and Fleming et al [35,36] In a subsequent set of experiments, the influence of the presence of well-defined micropores on the catalytic conversion of thiophenes was analyzed. For this purpose, measure- Figure 1.…”

X-ray, tautomeric preference, vibrational spectra, and density functional studies on benzoxazole and benzoxazoline derivatives

“…Since their thiol (mercapto, or sulfanyl) and thione derivates are fungicidal and bacteriostatic reagents, they are efficient corrosion inhibitors for many metals and their alloys, and are used in recirculation of water systems and in regulating plant growth [3][4][5][6][7][8][9][10]. They find a great variety of applications in surface science because they form adsorptive monolayers on metal and semiconductor substrates [11][12][13][14]. They are chelating agents with the presence of nitrogen, oxygen and sulfur in their contents.…”
