Intramolecular MLOH/π and MLNH/π interactions in crystal structures of metal complexes
(Versita, Warsaw, 2009)
Intramolecular metal-ligand OH/π (MLOH/π) and metal-ligand NH/π (MLNH/π) interactions in transition metal complexes between aqua or ammine ligand and ligand containing a C6-aromatic ring were investigated in crystal ...
Organic geochemical study of the upper layer of Aleksinac oil shale in the Dubrava block, Serbia
(Estonian Academy Publishers, Tallinn, 2017)
A detailed evaluation of geochemical properties of oil shale samples,from the outcrops of the Lower Miocene upper layer in the Dubrava area, Aleksinac basin, Serbia, was performed. For that purpose X-ray diffraction (XRD) ...
Surface characterization, hemo- and cytocompatibility of segmented poly(dimethylsiloxane)-based polyurethanes / Površinska karakterizacija, hemo- i citokompatibilnost segmentiranih poliuretana na bazi poli(dimetilsiloksana)
(Association of Chemical Engineers of Serbia, 2014)
Segmented polyurethanes based on poly(dimethylsiloxane), currently used for biomedical applications, have sub-optimal biocompatibility which reduces their efficacy. Improving the endothelial cell attachment and blood-contacting ...
Perlite as a potential support for nickel catalyst in the process of sunflower oil hydrogenation
(Maik Nauka/Interperiodica/Springer, New York, 2015)
Investigation was conducted in order to elucidate the possibility of using perlite as support for preparation of nickel based precursor catalyst, potentially applicable in vegetable oil hydrogenation process. On three ...

Antimicrobial activity of fourteen diarylheptanoids isolated from the bark of black and green alder against twelve bacterial species (five Gram-positive and seven Gram-negative) and eight fungal strains has been reported. ...
Effect of the support and the reduction temperature on the formation of metallic nickel phase in Ni/silica gel precursors of vegetable oil hydrogenation catalysts
(Maik Nauka/Interperiodica/Springer, New York, 2011)
Ni/SiO(2) materials with identical composition (SiO(2)/Ni = 1.0) have been synthesized by precipitation of Ni(NO(3))(2) center dot 6H(2)O solution with Na(2)CO(3) solution on the silica gel, obtained at three different pH ...
The effect of polar solvents on the synthesis of poly(urethane-urea-siloxane)s / Uticaj polarnih rastvarača na sintezu poli(uretan-urea-siloksana)
(Serbian Chemical Society, 2012)
Segmented poly(urethane-urea-siloxanes) (PUUS) based on 4,4'- methylene diphenyl diisocyanate-ethylene diamine (MDI-ED) hard segments and hydroxypropyl-terminated poly(dimethylsiloxane) (PDMS, Mn = 1000 g mol-1) soft ...
Micromeria thymifolia Essential Oil Suppresses Quorum-sensing Signaling in Pseudomonas aeruginosa
(Natural Products Inc, Westerville, 2016)
The chemical composition, antimicrobial and antiquorum sensing activity of the essential oil of Micromeria thymifolia (Scop.) Fritsch were investigated. Limonene, piperitone epoxide and piperitenone epoxide were found as ...
Secondary metabolites of three endemic Centaurea L. species
