Gas exchange is essential for bioreactor cultivation of tissue engineered cartilage
(John Wiley & Sons Inc, New York, 1999)
Tissue engineered cartilage can be grown in vitro if the necessary physical and biochemical factors are present in the tissue culture environment. Cell metabolism and tissue composition were studied for engineered cartilage ...
The electro-oxidation of H-2 and H-2/CO mixtures on carbon-supported PtxMoy alloy catalysts
(Electrochemical Soc Inc, Pennington, 1999)
Electro-oxidation kinetics of H-2 and H-2/CO mixture were studied on bimetallic Pt-Mo catalysts supported on a high-surface-area carbon black. The Pt:Mo atomic ratios in the catalysts were 3:1 and 4:1. Characterization of ...
RTD analysis of a novel Taylor-Couette flow device for blood detoxification
(Amer Inst Chemical Engineers, New York, 1999)
Heparin is an anticoagulant used in extracorporeal procedures such as hemodialysis and open heart surgery. Unfortunately: heparin may induce potentially fatal complications in patients at high risk of bleeding. The use of ...
Glycidyl esters synthesis catalysed by ion-exchange resins
(Serbian Chemical Society, Belgrade, 1996)
Ion-exchange resins not previously used for this purpose were employed to study the synthesis of glycidyl esters. The reaction was carried out both with free acids and their sodium salts. The model reaction was the synthesis ...
Cobalt(II)-exchange in Zeolite A
(Akadémiai Kiadó, 1995)
The influence of the initial Co(2+) and Na(+) concentrations (Co(Co) and Co(Na), respectively) upon the exchange degree (y) of Na(+) by Co(2+) ions in Zeolite A at 20 oC has been studied. The observed increase of y with ...
A study of the tetrahallogenonickel(II) complexes by the Fenske-Hall molecular orbital method
(Society of Chemists and Technologists of Macedonia, 1995)
The coordination geometry and electronic structure of the NiX4(2-) complex ions (X=Cl, Br, I) have been studied by the Fenske-Hall SCF method. The calculation confirm the presence of tetrahedral over square-planar geometry. ...
A novel triclinically deformed chabazite-like aluminophosphate prepared in the presence of tris(1,2-diaminoethane)nickel(II) chloride
(Elsevier, 1998)
The tris(1,2-diaminoethane)nickel(II) complex was found to be a novel structure-directing agent for the preparation of the chabazite-like AlPO4-34 molecular sieve. During crystallization the complex undergoes a ligand ...
Formability of a high-strength Al Mg6.8 type alloy sheet
(Springer, New York, 1998)
Room temperature formability testing was performed on an AlMg6.8 type alloy sheet with a fully recrystallized structure (average grain diameter similar to 18 mu m) and after partial annealing with a retained deformed ...
(31)P NMR investigation of some microporous zincophosphates
(Serbian Chemical Society, 1996)
High field magic-angle spinning (MAS) (31)P-NMR investigations of novel porous zincophosphates and their cobalt-containing derivatives confirm the framework structure of alternating Zn(Co)O4 and PO4 tetrahedra. The MAS NMR ...
A Study of the Mn, Co and Ni Environment in the As-synthesized and Rehydrated-calcined Aluminophosphate with Chabazite-like Topology
(Croatian Chemical Society, 1999)
Diffuse-reflectance spectroscopy (DRS), X-ray absorption near-edge structure (XANES) and extended X-ray absorption fine structure (EXAFS) methods are applied to an investigation of Mn, Co and Ni local environments in MnAlPO, ...
