Electroanalysis And Electrocatalysis Using Poly(Vinylferrocenium) Perchlorate Coated Electrodes
(Blackwell Science Ltd, 1997)Electroanalytical applications based on the electrochemical behavior of the redox polymer, poly(vinylferrocenium) perchlorate (PVF+ClO4-) coated as a film on Pt surfaces, are described. This chemically modified surface is ... -
In Vitro Activity Of A New Echinocandin, Ly303366, Compared With Those Of Amphotericin B And Fluconazole Against Clinical Yeast Isolates
(Amer Soc Microbiology, 1997)The in vitro activity of LY303366, a new echinocandin derivative, was evaluated with 191 yeast isolates by a broth microdilution method. The MICs at which 50% of the isolates were inhibited were 0.125 mu g/ml for Candida ... -
Composition Of Gamma-Ray Induced Triethoxyvinylsilane Methyl Methacrylate Copolymers Determined By Xps
(Elsevier Sci Ltd, 1998)Methyl methacrylate (MMA) was copolymerized with triethoxyvinylsilane (TEVS) using Co-60-gamma radiation at varying masses of the liquid monomers in the feed. Their homopolymers PMMA and PTEVS were also prepared by the ... -
Uv-Vis, Ir And Xps Analysis Of Uv Induced Changes In Pvc Composites
(Elsevier Science Bv, 1999)PVC undergoes a high degree of dehydrochlorination when exposed to energetic photons. The released HCl (acid), however, can be trapped if a suitable trapping material (base) is also enclosed within the solid matrix as a ... -
Tc-Glutathione Complex (Tc -Gsh) : Labelling, Chemical Characterization and Biodistribution in Rats
(1999)The chemical structure of 99mTc-GSH has been estabilished using the 99Tc isotope. Labeling of glutathione with technetium in the presence of stanous chloride gave a high yield result. In a comparative study between 99Tc ... -
Swelling Behavior of Poly(N-Vinyl-2-Pyrrolidone) and Poly(N-Vinyl-2-Pyrrolidone)/K2S2O8 Hydrogels in Urea Solutions
(John Wiley & Sons Inc, 2000)Hydrogels with varying cross-linking densities and average molecular weights between two consecutive cross-links were prepared from the binary poly(N-vinyl-2-pyrrolidone)/water and ternary poly(Nw-vinyl-2-pyrrolidone)/water/K2S2O8 ... -
Doping Of 2-Cl-Pani/Pvc Films By Exposure To Uv, Gamma-Rays And E-Beams
(Elsevier Science Sa, 2000)2-Chloro-polyaniline (2Cl-PANI) is chemically prepared in its non-conducting (Emeraldine Base, EB) form and dissolved together with polyvinylchloride (PVC) in THF for casting into thin (10-50 mu m) composite films. The ... -
