A Reexamination of Correlations of Amino Acids with Particular Secondary Structures
(Springer, New York, 2009)
Using the data from Protein Data Bank the correlations of primary and secondary structures of proteins were analyzed. The correlation values of the amino acids and the eight secondary structure types were calculated, where ...
Oxidation of formic acid on platinum surfaces decorated with cobalt(III) macrocyclic complexes
(Maik Nauka/Interperiodica/Springer, New York, 2009)
Platinum electrode decorated with three different mixed-ligand cobalt(III) complexes of the general formula [Co(Rdtc)cyclam](ClO4)(2) [cyclam = 1,4,8,11-tetraazacyclotetradecane, Rdtc(-) = morpholine-(Morphdtc), ...
Macroporous poly(glycidyl methacrylate-co-ethylene glycol dimethacrylate) resins-Versatile immobilization supports for biocatalysts
(Elsevier, 2009)
Crosslinked macroporous hydrophilic poly(glycidyl methacrylate-co-ethylene glycol dimethacrylate)s [abbreviated poly(GMA-co-EGDMA)] with identical chemical structure (60% of glycidyl methacrylate) but with varied average ...
Elektrohemijsko dobijanje i morfologija čestica bakarnog praha dobijenog pri različitim retimima elektrolize / Electrodeposition and morphology of copper powder particles obtained at different current regimes
(Bosnia and Herzegovina : University of East Sarajevo, Faculty of Technology, 2009)
Ispitivan je uticaj različitih reţima elektrolize (konstantna i reversna struja) na morfologiju bakarnog praha. Morfologija istaloţenog bakarnog praha je proučavana pomoću skening elektronskog mikroskopa (SEM). Diskutovan ...
Structure sensitivity of dimethylamine deep oxidation over Pt/Al2O3 catalysts
(Elsevier, 2009)
The deep oxidation of dimethylamine (DMA) was studied over Pt/Al2O3 catalysts with small (1 nm) and large (7.8-15.5 nm) Pt crystallite sizes. The turnover frequency (TOF) was higher for the large than for the small Pt ...
Corrosion causes in thermal power plants and ways of prevention / Uzroci korozije u termoenergetskim postrojenjima i načini prevencije
(Belgrade, Serbia : Engineering Society for Corrosion, 2009)
Corrosion damages often exert considerable influence on outages number and hence on the loss of thermal power plant availability. In order to accomplish the aim of reducing the corrosion to it's minimum and prevent main ...
Ethylene oxide removal by sorption on aluminium oxide / Uklanjanje etilen oksida sorpcijom na aluminijum oksidu
(Association of Chemical Engineers of Serbia, 2009)
The dynamics of ethylene oxide sorption and desorption on Al2O3 sorbent were investigated. The investigations of ethylene oxide sorption on Al2O3 show that significant sorption appeared above 125°C. The removal of sorbed ...
Synthesis of the first thiazolidine-condensed five-, six-, and seven-membered heterocycles via cyclization of vinylogous N-acyliminium ions
(Synlett, 2009)
Synthesis of new thiazolidine-fused five-, six-, and seven-membered heterocycles through vinylogous N-acyliminium ion-cyclization sequence, involving positions 3 and 4 of the thiazolidine ring, is described. The formation ...
Synthesis and characterization of self-assembled polyaniline nanotubes/silica nanocomposites
(American Chemical Society (ACS), 2009)
Self-assembled semiconducting, paramagnetic polyaniline nanotubes have been synthesized by the oxidative polymerization of aniline with ammonium peroxydisulfate in aqueous medium in the presence of colloidal silica particles ...
