Investigation of pretertiary and tertiary surface sediments from Serbia: Organic geochemical interpretation / Ispitivanje pretercijarnih i tercijarnih površinskih sedimenata Srbije - organsko-geohemijska interpretacija
(Association of Chemical Engineers of Serbia, 2002)
Samples of surface sediments originating from different localities in Serbia which contained more than 0.5 % organic matter were investigated in this paper. According to age, these samples were classified into two groups ...
Antimalarial peroxides: The first intramolecular 1,2,4,5-tetraoxane / Antimalarijski peroksidi - prvi intramolekulski 1,2,4,5-tetraoksan
(Serbian Chemical Society, 2002)
An intramolecular steroidal 1,2,4,5-tetraoxane has been synthesised in six steps starting from methyl3-oxo-7α,12α-diacetoxy-5β-cholan-24-oate. The synthesised 1,2,4,5-tetraoxane has moderate in vitro antimalarial activity ...
The estimation of solid copper surface tension in copper sulfate solutions / Procena vrednost i površinskog napona čvrstog bakra u rastvorima bakar-sulfata
(Serbian Chemical Society, 2002)
In metal electrodeposition in the limiting diffusion current density range the deposition current density remains constant regardless of the deposition overpotential used. At the same time, the larger the deposition ...
