Methanol oxidation at platinum electrodes in acid solution: Comparison between model and real catalysts / Oksidacija metanola na platinskim elektrodama u kiseloj sredini - poređenje model i realnih katalizatora
(Serbian Chemical Society, 2006)
Methanol oxidation in acid solution was studied at platinum single crystals, Pt(hkl), as the model catalyst, and at nanostructural platinum supported on high surface area carbon, Pt/C, as the real catalyst. The linear ...
Nanofabrication of planar split ring resonators for negative refractive index metamaterials in the infrared range / Nanofabrikacija planarnih split ring rezonatora za metamaterijale sa negativnim indeksom prelamanja u infracrvenom opsegu
(Serbian Chemical Society, 2006)
Experimental nanofabrication of planar structures for one-dimensional metamaterials designed to achieve a negative effective refractive index in the mid-infrared range (5-10 micrometers) was performed. Double split ring ...
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.
Physical modeling of representative particles of electrodeposited copper powders / Fizičko modelovanje reprezentativnih čestica elektrohemijski istaloženog bakarnog praha
(Serbian Chemical Society, 2006)
A method for the estimation of the size of the representative particle of a copper powder is given. Cross sections of representative particles of flowing and non-flowing powders estimated by this procedure are also presented.
Phytochemical investigation of Anthemis cotula / Фитохемијско испитивање биљне врсте Anthemis cotula
(Serbian Chemical Society, 2006)
The investigation of roots of Anthemis cotula (Asteraceae) from east Serbia revealed, in addition to polyacetylenes previously isolated from the same species, three prenylated 4-hydroxyacetophenones, detected for the first ...
Activity and stability of RuO2-coated titanium anodes prepared via the alkoxide route / Aktivnost i stabilnost titanskih anoda sa prevlakom od oksida rutenijuma dobijenom alkoksidnim postupkom
(Serbian Chemical Society, 2006)
Titanium anodes with an active RuO2 coating of two different thicknesses were prepared from the oxide suspended in ethanol ("ink" method), while the oxide itself was synthesized by the hydrolysis of ruthenium ethoxide in ...
Influence of N-1 substituent properties on binding affinities of arylpiperazines to the binding site of 5-HT1A receptor / Uticaj osobina N-1 supstituenta na afinitet arilpiperazina prema vezivnom mestu 5-HT1A receptora
(Serbian Chemical Society, 2006)
Serotonin receptors (5-HTRs), especially the 5-HT1A subtype, have been the subject of intensive research for the past decade, due to their function in human physiology. Several structurally different classes of ligands are ...
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 ...
Determination of silanol end groups in polysiloxanes obtained from dimethyldichlorosilane hydrolysate (DDSH) / Odredjivanje silanolnih krajnjih grupa u polisiloksanima dobijenim iz dimetildihlorsilan hidrolizata (ddsh)
(Serbian Chemical Society, 2006)
Dimethyldichlorosilane hydrolysate, DDSH, the linear part of which contains SiOH end groups, can be used in the preparation of difunctionally terminated (any end groups other than SiOH) polysiloxanes via equilibration ...
Factors affecting the microstructure of porous ceramics / Faktori koji utiču na mikrostrukturu porozne keramike
(Serbian Chemical Society, 2006)
In this study, porous ceramics were produced by using two methods: the polymeric sponge and foam method. A study of the effect of viscosity on the characteristics of the final product produced using the polymeric sponge ...
