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 ...
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 ...
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 ...
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. ...
Isomorphous element substitution in the chabazite-like aluminophosphate framework
(Akademiai Kiado Zrt, Budapest, 1998)
Thermal investigations and Fenske-Hall SCF MO calculations have been used for studying isomorphous element substitution in the chabazite-like aluminophosphate framework prepared in the presence of tetraethylammonium hydroxide ...
Room temperature deformation behaviour of A1Mg6.5 alloy sheet
(Carl Hanser Verlag, Munich, 1999)
Room temperature tensile test have been performed with initial strain rates of 6.7 x 10(-4) s(-1), 6.7 x 10(-3) s-(1) and 6.7 x 10(-2) s(-1), on AlMg6.5 alloy sheet, after imposing 5% to 70% cold rolling reductions, and ...
The determination of kinetics parameters of the hydrogen evolution on Ti-Ni alloys by ac impedance
(Pergamon-Elsevier Science Ltd, Oxford, 1997)
The kinetics and mechanism of hydrogen evolution at Ti-Ni alloys electrode has been studied by means of steady-state potentiostatic polarization and ac impedance spectrum measurements. Complex-plane spectrum plots are ...
Thermal investigations of some AlPO and MeAPO materials prepared in the presence of HF
(Elsevier, Amsterdam, 1997)
Hydrothermal synthesis of chabazite-like AlPO4 in a fluoride medium, using piperidine as the structure directing agent, is also successful in the preparation of transition-metal-modified AlPO products. The transition metal ...
