Kinetic studies of the deactivation of O 2 ( 1 Σ g + ) and O( 1 D)
(John Wiley & Sons, Inc., 1990-12)
The kinetics of the deactivation of O 2 ( 1 Σ g + ) is studied in real time. O 2 ( 1 Σ g + ) is generated in this system by the O( 1 D) + O 2 reaction following O 3 laser flash photolysis in the presence of excess ...
Heat capacities of the wustites Fe0.9379O and Fe0.9254O at temperatures T from 5 K to 350 K. Thermodynamics of the reactions: xFe(s) + (1/4)Fe3O4(s) = Fe0.7500+xO(s) = Fe1-yO(s) at T [approximate] 850 K, and properties of Fe1-yO(s) to T = 1000 K. Thermodynamics of formation of wustite
(Elsevier, 1993-09)
Thermodynamic properties of wustites prepared from iron and iron(III) oxide, have been studied by adiabatic calorimetry. Heat-capacity measurements of metastable Fe0.9379O and Fe0.9254O from T = 5 K to 350 K yielded the ...
H2O2-Induced Increases in Cellular F-Actin Occur without Increases in Actin Nucleation Activity
(Elsevier, 1994-02)
Previous work has shown that H2O2 causes an increase in polymerized actin (F-actin) inside cells. To test the hypothesis that increased polymerization resulted from a mechanism involving increased actin nucleation activity, ...
The role of deoxycytidine-metabolizing enzymes in the cytotoxicity induced by 3′-amino-2′,3′-dideoxycytidine and cytosine arabinoside
(Springer-Verlag, 1992-03)
The cellular metabolism of 3′-amino-2′,3′-dideoxycytidine (3′-NH 2 -dCyd), a cytotoxic agent previously reported to be a poor substrate for purified Cyd/dCyd deaminase (dCydD), was compared with that of cytosine arabinoside ...
Inhibition of cytotoxicity by intracellular superoxide dismutase supplementation
(Elsevier, 1990)
The role of intracecullar oxyradicals in H2O2 and neutrophil-induced cytotoxicity is suggested by previous studies showing protection by inhibitors such as deferroxamine, dimethylthiourea, and dimethyl sulfoxide. In the ...
Molybdenum nitride catalysts : I. Influence of the synthesis factors on structural properties
(Elsevier, 1994-03)
Effects of the synthesis parameters on the structural properties of molybdenum nitride catalysts, prepared by the temperature-programmed reaction of MoO3 with NH3, have been examined. Molybdenum trioxide was heated in ...
Evaluation of the simultaneous use of Cp 2 VMe 2 and CpTiCl 2 N(SiMe 3 ) 2 as precursors to ceramic thin films containing titanium and vanadium: Towards titanium–vanadium carbonitride
(John Wiley & Sons, Ltd., 1998-03)
Ceramic thin films containing titanium, vanadium, carbon, oxygen and nitrogen were obtained on steel substrates at 873 K, under nitrogen and helium gases and at low pressure, by chemical vapor deposition (CVD) from two ...
Simplified method of making alginate-polylysine microcapsules for hybridoma cell culture using RPMI 1640 medium
(Kluwer Academic Publishers; Science & Technology Letters ; Springer Science+Business Media, 1990-09)
The method of making alginate-poly-L-lysine microcapsules for hybridoma cell culture can be simplified by cultivating the cells in RPMI 1640 medium. Phosphate concentration in RPMI 1640 medium is sufficiently high to ...
