The biogeochemical alteration of an Mg-Fe orthopyroxene, reacted for 70 yr under and conditions in a desert environment, was Studied by transmission electron microscopy. For this purpose, an electron transparent cross-section of the interface between a sin ...
Permeable reactive barriers employing iron as a reactive surface have received extensive attention. A remaining issue, however, relates to their longevity. As an integral part of a long-term column study conducted to examine the influence of inorganic coso ...
The bacterial inactivation of Escherichia coli on Ag–cotton textiles were investigated under different experimental conditions with novel Ag-nanoparticles fixed on cotton textiles. The evaluation of the bactericide performance of the Ag–cotton was compared ...
The photocatalytic activity of TiO2–SiO2-coated cotton textiles was investigated through the self-cleaning of red wine stains. It was shown that a TiO2–SiO2 species could be produced at temperatures of 100 °C with acceptable photo-activity on non-heat resi ...
The repetitive discoloration kinetics of the azo-dye Methyl Orange (taken as a model organic compound) was followed under solar simulated radiation (90 mW/cm2) to assess the performance of the TiO2/Tedlar® composite photocatalyst. The influence of solution ...
Using a first-principles approach, we investigate the origin of the fine structure in Si 2p photoelectron spectra at the Si(100)-(2x1) surface and at the Si(100)-SiO2 interface. Calculated and measured shifts show very good agreement for both systems. By u ...
A novel lithium salt, cyclobutane-1,1-dicarboxylic lithium was synthesized and characterized by NMR, IR, ESI-MS, X-ray single crystal analysis, and TG/DTG (TGA) thermal analysis. The crystal structure information reveals the coordination polymer nature and ...
The two known Me- and allyl-substituted 1H-imidazol-3-ium bromides 1 and 2, respectively, were converted to the corresponding BF4- and BPh4- salts 3-6 (Scheme 1). Compounds 3 and 4 were liquids at ambient temperature. Reaction of 1 or 2 with [PdCl2] afford ...
A new type of Nafion/Fe structured membrane ensuring faster kinetics, higher efficiency, and mechanical properties has been prepared and will be compared in its performance with the Fe-exchanged commercial Dupont 117 Nafion/Fe membrane during the abatement ...
Proton insertion in polycryst. tungsten oxide has been studied with photoelectron spectroscopy and semi-empirical calcns. The W 4f spectra show growth of W5+ and W4+ oxidn. states as a function of inserted proton content in the crystal lattice. A concomita ...
