Morphology of Ni-Mo-O alloy powders electrodeposited from ammonium sulfate solutions / Morfologija prahova Ni-Mo-O legura istaloženih elektrohemijskim postupkom iz rastvora amonijum sulfata
(Belgrade, Serbia : Engineering Society for Corrosion, 2008)
The electro deposition of the Ni-Mo-O alloy powders from ammonium sulfate containing electrolytes of different Ni/Mo ions concentration ratios was investigated by the polarization measurements. In all electrolytes similar ...
Sinteza alifatskih hiperrazgranatih poliestara: "pseudo one-step" procedura“
(Belgrade : Serbian Chemical Society, 2008)
Hiperrazgranati polimeri (HBP) i dendrimeri pripadaju klasi dendritskih makromolekula. Za razliku od složene i dugotrajne sinteze dendrimera, HBP se mogu sintetisati korišćenjem jednostavne "one-step" procedure, pri čemu ...
Rheological and thermogravimetric analysis of unmodified and modified aliphatic hyperbranched polyester
(The Society of Physical Chemists of Serbia, 2008)
The influence of the type of end groups on the rheological and thermal properties of aliphatic hyperbranched polyesters (AHBP) was investigated in this work. Unmodified, hydroxy-functional AHBP sample of third pseudo ...
Termičke karakteristike nanokompozita Ag/PS
(Društvo inženjera plastičara i gumara IPG, Beograd, Srbija, 2008)
U radu je ispitivan uticaj nanočestica srebra (Ag) na termičke karakteristike polimerne matrice polistirena (PS). Ispitivanja su vršena metodom termogravimetrijske analize (TGA) u azotu u zavisnosti od koncentracije ...
Synthesis and characterization of crosslinked polyurethanes
(The Society of Physical Chemists of Serbia, 2008)
Two polyurethane samples, crosslinked with aliphatic hyperbranched polyester, were synthesized and examined in this work. The sample PUPDMS-EO was prepared using ethylene oxide-poly(dimethylsiloxane)-ethylene oxide as ...
Ribofuranose as a carrier of tetraoxane and 4-aminoquinoline antimalarial pharmacophores / Ribofuranoza kao nosač tetraoksanske i 4-aminohinolinske antimalarijske farmakofore
(Belgrade : Serbian Chemical Society, 2008)
Several tetraoxane and 4-aminoquinoline molecules were prepared in
order to examine the influence of ribofuranose as a carrier molecule on the antimalarial
activity of test compounds. The synthesized compounds showed ...
The role of catalysis in sustainable development
(Novi Sad, Serbia : The Serbian Academy of Science and Arts, Branch in Novi Sad, 2008)
In this paper basic concepts of sustainable development are given together with brief retrospective of development of catalysis. Impacts of catalysis on economic and particularly environmental sustainability are discussed. ...
Sinteza i karakterizacija nanokompozita Ag/PS
