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 ...
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. ...
Removal of methyl tertiary butyl ether from wastewaters using photolytic, photocatalytic and microbiological degradation processes
(Elsevier B.V., 2007)
Contamination of groundwater by methyl tertiary butyl ether (MTBE), that is detected in wastewater of petrochemical industry, is an increasing problem to water supply companies. The subjects of this research were the methods ...
Formation of dish-like holes and a channel structure in electrodeposition of copper under hydrogen co-deposition
(Elsevier, 2007)
Copper electrodeposition from acid sulfate solutions at an overpotential of 1000 mV, which is about 250 mV outside the plateau of the limiting diffusion current density, was examined by the determination of the average ...
Consequences of MnSOD interactions with nitric oxide: Nitric oxide dismutation and the generation of peroxynitrite and hydrogen peroxide
(USA :Taylor & Francis INC, 2007)
The present study demonstrates that manganese superoxide dismutase (MnSOD) Escherichia coli, binds nitric oxide (NO) and stimulates its decay under both anaerobic and aerobic conditions. The results indicate that previously ...
Antiproliferative activity of β-hydroxy- β-arylalkanoic acids
(MDPI, 2007)
Article describes the synthesis of fifteen β-hydroxy- β-arylalkanoic acids by Reformatsky reaction using the 1-ethoxyethyl-2- bromoalkanoates, aromatic or cycloalkyl ketones or aromatic aldehydes. The short survey of ...
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 ...
Yb3+ doped dyphillosilicates prepared by thermally induced phase transformation of zeolites
(Maik Nauka/Interperiodica/Springer, New York, 2007)
Yb3+-doped Ba and Sr diphyllosilicates (hexacelsians) have been synthesized using the Na form of LTA zeolite by ion-exchange procedure and thermal treatment. The crystal structures of both doped samples are refined and ...
Synthesis of some steroidal oximes, lactams, thiolactams and their antitumor activities
(Elsevier, 2007)
The antiproliferative activity of previously synthesized (Z)-cholest-4-en-6-one oxime (1), (E)-cholest-4-en-6-one oxime (2), 7-aza-B-homocholest-4-en-6-one (3) and 6-aza-B-homocholest-4-en-7-one (4) and newly synthesized ...
The qualitative electrochemical determination of clarithromycin and spectroscopic detection of its structural changes at gold electrode
(Elsevier, 2007)
The aim of the present study was the qualitative determination of the pure clarithromycin using a gold electrode in neutral electrolyte by cyclic linear sweep voltammetry. It was shown that in the range of -1.2 V to 1.0 V ...
