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 ...
Prediction of the particle circulation rate in a draft tube spouted bed suspension dryer / Predviđanje cirkulacije čestica u sušioniku za suspenzije sa modifikovanim fontanskim slojem
(Serbian Chemical Society, 2006)
A model for predicting the particle circulation rate in a draft tube spouted bed dryer with inert particles is proposed and verified. The calculation algorithm requires three input values: the gas velocity in the draft ...
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.
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 ...
