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 ...
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 ...
Ballistic magnetoresistance versus magnetostriction effects in electrodeposited nanocontacts at room temperature
(Institute of Electrical and Electronics Engineers, Inc., 2003)
The authors present experiments and discuss recent results on ballistic magnetotesistance in nanometer size (on the order of 1 to 10 nm) nanocontacts grown by electrodeposition in
thin wires and in thin films of a few ...
Conformational analysis of octa- and tetrabromo tetraphenylporphyrins and their Ni(II) and Tb(III) complexes
(Elsevier Science Inc, New York, 2004)
Molecular mechanics (MM) calculations were used to analyze the puckering of metalloporphyrins as a function of metal ion size and the position of substituents on the porphyrin periphery, on a three series of octa- and ...
Efflux of cholesterol and phospholipids derived from the haemoglobin-lipid adduct in human red blood cells into plasma
(Elsevier, 2007)
Objective: The interior of red blood cells (RBCs) contains a variable amount of cholesterol and phospholipids bound to haemoglobin (Hb). This current study was devised to determine if this pool of lipids (termed Hb-Ch) was ...
Rheological properties of concentrated solutions of aliphatic hyperbranched polyesters
(Willey, 2007)
The rheological investigation of concentrated solutions of aliphatic hyperbranched polyesters
(AHBP) in N-methyl-2-pyrrolidinon (NMP) is presented. Two series of hydroxy-functional
AHBP were synthesized using pseudo-one-step ...
Influence of α-Fe2O3 nanorods on the thermal stability of poly(methyl methacrylate) synthesized by in situ bulk polymerisation of methyl methacrylate
(Elsevier, 2008)
α-Fe2O3 nanorods were incorporated into poly(methyl methacrylate) (PMMA) by in situ radical polymerisation of methyl methacrylate initiated by 2,2′-azobisisobutyronitrile. The α-Fe2O3 nanorods were synthesized by forced ...
Thermal degradation of aliphatic hyperbranched polyesters and their derivatives
(Elsevier, 2006)
In this study results of thermal degradation of aliphatic hyperbranched polyesters, AHBP, and their derivatives, determined by non-isothermal thermogravimetric analysis in inert atmosphere (N2) are presented. The thermal ...
Conformations of the Nine-Membered Ring in the B-Nor-5,10-secosteroids. X-Ray and NMR Analysis
(Wiley, 2005)
The conformations of (Z)‐ and (E)‐5‐oxo‐B‐nor‐5,10‐secocholest‐1(10)‐en‐3β‐yl acetates (2 and 3, resp.) were examined by a combination of X‐ray crystallographic analysis and NMR spectroscopy, with emphasis on the geometry ...
