Magnetic Anisotropy of the C-C Single Bond
(Wiley-V C H Verlag Gmbh, Weinheim, 2013)
Anisotropic effects are broadly used in NMR spectroscopy for structure elucidation. With the development of computational methods it has become possible to quantify the effects and obtain further insight into their origin. ...
Silica Gel as a Promoter of Sequential Aza-Michael/Michael Reactions of Amines and Propiolic Esters: Solvent- and Metal-Free Synthesis of Polyfunctionalized Conjugated Dienes
(Wiley-V C H Verlag Gmbh, Weinheim, 2018)
We present an efficient, simple, metal- and solvent-free silica-gel-promoted synthesis of functionalized conjugated dienes by sequential aza-Michael/Michael reactions by starting from commercially available primary amines ...
Energy decomposition analysis of gauche preference in 2-haloethanol, 2-haloethylamine (halogen = F, Cl), their protonated forms and anti preference in 1-chloro-2-fluoroethane
(Royal Soc Chemistry, Cambridge, 2015)
2-Haloethanol and 2-haloethylamine (halogen = F, Cl) prefer gauche conformation. This preference is significantly increased upon protonation. Commonly used explanations are based on intramolecular hydrogen bonding and ...
Copper-Sulfate Pentahydrate as a Product of the Waste Sulfuric Acid Solution Treatment
(Springer, New York, 2012)
The aim of this study is synthesis of copper-sulfate pentahydrate from the waste sulfuric acid solution-mother liquor generated during the regeneration process of copper bleed solution. Copper is removed from the mother ...
H-1 NMR Chemical Shifts of Cyclopropane and Cyclobutane: A Theoretical Study
(American Chemical Society (ACS), 2013)
This study was undertaken in order to rationalize the peculiar H-1 NMR chemical shifts of cyclopropane (delta 0.22) and cyclobutane (delta 1.98) which are shifted upfield and downfield with respect to larger cycloalkanes ...
Synthesis of thiazolidine-fused heterocycles via exo-mode cyclizations of vinylogous N-acyliminium ions
(Royal Soc Chemistry, Cambridge, 2012)
Syntheses of thiazolidine-fused heterocycles via exo-mode cyclizations of vinylogous N-acyliminium ions incorporating heteroatom-based nucleophiles have been examined and discussed. The formation of (5,6)-membered systems ...
Effect of malondialdehyde on the ovalbumin structure and its interactions with T84 epithelial cells
(Elsevier, 2017)
Background: Protein oxidation can occur as a consequence of lipid peroxidation during food processing. The aim of this work was to explore the effect of malondialdehyde (MDA) modification of ovalbumin (OVA) on its interaction ...
Far Infrared Reflectivity Properties of BaTiO3 Ceramics
(Carl Hanser Verlag, 2001)
Far-infrared and infrared reflectivity measurements have been made on pure BaTiO3, BaTiO3 doped with 5 mol% LiF and (Ba,Ca,Pb)TiO3 at room temperature in the range between 50 and 1000 cm–1. A fitting procedure, based on a ...
Coinfection and Interference Phenomena Are the Results of Multiple Thermodynamic Competitive Interactions
(MDPI, 2021)
Biological, physical and chemical interaction between one (or more) microorganisms and a host organism, causing host cell damage, represents an infection. Infection of a plant, animal or microorganism with a virus can ...
A contribution to the knowledge of electrochemical deposition of W induced by Ni
(Elsevier Sequoia SA, 2000)
It was found that codeposition of Ni and W from an ammonia and citrate-containing electrolyte, is very sensitive to changes in operating conditions. The Ni-W alloy deposit exhibited sensitivity of chemical composition and ...
