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 ...
Oxidative Fragmentations of the 5-alpha and 5-beta-Hydroxy-B-norcholestan-3-beta-yl Acetates
(Wiley, 2003)
Oxidations of 5α‐hydroxy‐B‐norcholestan‐3β‐yl acetate (8) with Pb(OAc)4 under thermal or photolytic conditions or in the presence of iodine afforded only complex mixtures of compounds. However, the HgO/I2 version of the ...
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. ...
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 ...
Synthesis and molecular structure investigation of aliphatic hyperbranched polyesters
(Nova Science, 2009)
The results obtained by investigation of the influence of synthesis procedure on the molecular structure of aliphatic hyperbranched polyesters (AHBP) are presented in this work. Different pseudo generations of these ...
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 ...
Thermal behaviour of Ag/PMMA nanocomposites synthesized by in situ method
(Institute of Technical Sciences of the Serbian Academy of Sciences and Arts, 2008)
The influence of the surface modified silver nanoparticles (Np), used as a filler, on the thermal properties poly(methylmethacrylate) (PMMA) matrix, synthesized by “in situ” radical polymerization process, was studied. The ...
Synthesis and characterization of aliphatic hyperbranched polyesters
(The Society of Chemists and Technologists of Macedionia, 2008)
The synthesis of dendritic polymers, i.e., dendrimers (ideally branched) and hyperbranched polymers (non-ideally
branched) and investigation of their properties have gained large scientific attention over the last twenty ...
