Enhancement of the electrochemical reduction of oxygen at platinum by nickel underpotential deposition
(Springer Nature, 2006)
Polycrystalline Pt electrode was modified by underpotential deposition (upd) of nickel. The modification was performed by potential cycling in phosphate buffer pH7. 0 containing NiSO 4 , in which hydrogen and nickel upd ...
Solvent, structural, quantum chemical study and antioxidative activity of symmetrical 1-methyl-2,6-bis[2-(substituted phenyl)ethenyl]pyridinium iodides
(Springer, 2018)
15 symmetric 1-methyl-2,6-bis[2-(substituted phenyl)ethenyl]pyridinium iodides were synthesized in this work. Their structures were characterized using IR, H-1 and C-13 NMR, and UV-Vis spectroscopy. DFT calculations indicated ...
Assessing the dispersive and electrostatic components of the selenium-aromatic interaction energy by DFT
(Springer, New York, 2017)
Selenium has been increasingly recognized as an important element in biological systems, which participates in numerous biochemical processes in organisms, notably in enzyme reactions. Selenium can substitute sulfur of ...
One-step conversion of ketones to conjugated acids using bromoform
(Synthetic Communications, 2009)
Phase-transfer-catalyzed (PTC) reactions of ketones with bromoform and aqueous lithium hydroxide in alcoholic solvent result in the formation of ,-unsaturated carboxylic acids. The reaction was performed at room temperature ...
Structural analysis of conformational flexibility in (aqua) (propanediamine-N,N'-diacetato-N-propionato)chromium(III) dihydrate. Crystal structure of cis-polar, trans(H2O, O-5)-[Cr(1,3-pddap)(H2O)]center dot 2H(2)O
(Taylor & Francis Ltd, Abingdon, 2007)
The quinquedentate complex trans(H2O,O-5)-[Cr(1,3-pddap)(H2O)].2H(2)O (where 1,3-pddap is the 1,3-propanediamine-N, N '-diacetate-N-3-propioriate ion) was prepared and its structure established by X-ray diffraction method. ...
Yeast surface display for the expression, purification and characterization of wild-type and B11 mutant glucose oxidases
(Academic Press Inc Elsevier Science, San Diego, 2013)
Glucose oxidase (GOx) catalyzes the oxidation of glucose to form gluconic acid and hydrogen peroxide, a reaction with important applications in food preservation, the manufacture of cosmetics and pharmaceuticals, and the ...
A Synergy of ZnO and ZnWO4 in Composite Nanostructures Deduced from Optical Properties and Photocatalysis
(Springer/Plenum Publishers, New York, 2013)
ZnO/ZnWO4 composite rod-like nanoparticles were synthesized by low-temperature soft solution method at 95 A degrees C with different reaction times (1-120 h), in the presence of non-ionic copolymer surfactant Pluronic F68. ...
Examinations of cross-linked polyvinylpyridine in open reactor
(Materials Science Forum, 2005)
Macroporous cross-linked copolymer of 4-vinylpyridine and 25% (4:1) divinylbenzene is analyzed under open conditions, that is in a continuous well-stirred tank reactor (CSTR). With this aim the appropriate bifurcation ...
Allozyme polymorphism of Mdh and alpha-Gpdh in Ixodes ricinus populations: comparison of borreliae-infected and uninfected ticks
(Springer, Dordrecht, 2006)
Ixodes ricinus Linnaeus (Acari: Ixodidae) ticks are vectors of numerous infectious diseases in humans and animals. The allozyme variability of MDH and alpha-Gpdh was detected by native polyacrylamide gel electrophoresis ...
