Pulse and direct current plating of Ni-W alloys from ammonia-citrate electrolyte
(Elsevier, 2006)
The effect of the potential of deposition and electrode rotation rate on current efficiency and partial current density of nickel deposition from ammonia-citrate electrolyte with and without tungstate ions was investigated. ...
Tetraoxane antimalarials and their reaction with Fe(II)
(American Chemical Society (ACS), 2006)
Mixed tetraoxanes 5a and 13 synthesized from cholic acid and 4-oxocyclohexanecarboxylic acid were as active as artemisinin against chloroquine-susceptible, chloroquine-resistant, and multidrug-resistant Plasmodium falciparum ...
Synthesis, biology, and modeling of a C-4 carbonyl C,D-seco-taxoid
(Oxford : Pergamon-Elsevier Science Ltd, 2006)
A C,D-seco-paclitaxel derivative 26 was prepared from taxine and tested for biological activity. Chemical reactivity of the seco-compounds proved to be substantially modified, with respects to taxoids. The corresponding ...
Reactions of α-4(20)-epoxy-5-O-mesyltriacetyltaxicine I induced by Bf3·Et2O/Bu4NBr / Reakcije α-4(20)-epoksi-5-O-meziltriacetiltaksicina I sa tetrabutilamonijum-bromidom u prisustvu bortrifluorid-eterata
(Serbian Chemical Society, 2006)
The reaction of α-4(20)-epoxy-5-O-mesyltriacetyltaxicine I (2) with BF3·Et2O/Bu4NBr can give rise to 4 different products. Each of these products can be obtained selectively, under the appropriate reaction conditions.
The cellular fatty acid composition of Bradyrhizobum japonicum and Sinorhizobium meliloti strains / Ćelijske masne kiseline sojeva Bradyrhizobum japonicum i Sinorhizobium meliloti
(Acta biologica iugoslavica - serija B: Mikrobiologija, 2006)
Microbial fatty acid analysis represents a simple and rapid method for identification of strains mainly for taxonomic purpose. Fatty acid composition in the whole cells and lipopolysaccharides in Rhizobiaceae were studied ...
Further guaianolides from Amphoricarpos neumayeri ssp murbeckii from Montenegro
(Verlag Z Naturforsch, Tubingen, 2006)
The aerial parts of Amphoricarpos neumayeri ssp. murbeckii afforded eleven guaianolides with the same relative (1 alpha H,4 beta H,5 alpha H, 7 alpha H) configuration of the basic skeleton. All of them contained a CH2OX ...
Activity of a PtBi alloy in the electrochemical oxidation of formic acid
(Elsevier, 2006)
Formic acid oxidation in acid solution was examined on a PtBi alloy characterized by X-ray photoelectron spectroscopy. Three chemical states of Bi, i.e., PtBi or Bi(0), Bi2O3 and BiO(OH) were found. Electrochemical ...
