Pure and K-doped vanadia/titania prepared by different methods have been studied in order to elucidate the role of vanadia species (monomeric, polymeric, bulk) in catalytic toluene partial oxidation. The ratio of different vanadia species was controlled by ...
Medical-grade poly(vinyl chloride) (PVC) was chemically modified to study how the incorporation of monovalent silver influences Pseudomonas aeruginosa adhesion and colonization. The modification investigated consisted of a radio frequency-oxygen (RF-O-2) g ...
In the presence of sulfur dioxide and an acid promoter, (-)-(1E,3Z)-2-methyl-1-((1S)-1-phenyleth- oxy)penta-1,3-dien-3-yl isobutyrate reacts with (Z)-3-(trimethylsilyloxy)-pent-2-ene giving a silyl sulfinate intermediate that undergoes, in the presence of ...
The adsorption and ordering of the molecule terephthalic acid (TPA), 1,4-benzene-dicarboxylic acid C6H4-(COOH)(2), on the reconstructed Au(111) surface has been studied in situ in ultrahigh vacuum by scanning tunneling microscopy (STM) at room temperature. ...
Polyethylene terephthalate films were surface-modified with polyethylene oxide (18,500 g/mol) using a solution technique described previously. These films were investigated for their resistance to bacterial adhesion. Three bacterial strains most commonly a ...
Protected forms of exo-5-amino-exo-6-hydroxy-7-oxabicyclo [2.2.1]heptan-2-one and of exo-5-amino-endo-6-hydroxy-7-oxabicyclo[2.2.1]heptan-2-one can be obtained readily and with high stereoselectivity from exo-2-cyano-7-oxabicyclo[2.2.1]hept-5-en-2-yl aceta ...
The efficiency of a two-step ozonation with regard to disinfection and oxidation of micropollutants; was assessed for a river-water treatment plant (Limmat River, Zurich, Switzerland). The assessment was based on laboratory experiments to estimate transien ...
The present work investigates the mechanical integrity of multilayer films developed for flexible displays. The layers comprise tin-doped indium oxide (ITO) conductive coatings and alumina barrier coatings sputtered onto high temperature aromatic polyester ...
The influence of substrate compn. on the yield, nature, and compn. of exopolysaccharides (EPS) produced by the food-grade strain G. xylinus I-2281 was investigated during controlled cultivations on mixed substrates contg. acetate and either glucose, sucros ...
Employing a combined filtration and pptn. method, the endotoxin concn. in sodium alginate (SA) and sodium cellulose sulfate (SCS) was reduced to a value of 200 EU/g polymer. This is one-tenth of the regulatory threshold calcd., e.g., for an appropriate bio ...
