Characterization of PDMS membranes fabricated by bulkmicromachining on silicon wafers
(Belgrade : Military Technical Institute, 2014)
In this paper we proposed microfabrication scheme for PDMS (Polydimethylsiloxane) thin membrane fabrication on Si micromachined cavities with square cross section. PDMS network samples for this research were synthesized ...
Potential environmental application of microbial polysaccharides
(Abstracts CD - 23rd Symposium on Environmental Chemistry, Kyoto, Japan, 2014)
Here we report toxicity inhibition effect of microbial exopolysaccharides on copper (II) in acute toxicity tests with Artemia salina and Daphnia magna.
Synthesis and biological evaluation of 5-substituted derivatives of benzimidazole
(Serbian Chemical Soc, Belgrade, 2014)
A series of eight novel 5-substituted derivatives of benzimidazole was synthesized by condensation of the corresponding diamine with ethyl 4-[4-(2-chlorophenyl)piperazin-1-yl]butanoate in refluxing 4 M hydrochloric acid. ...
Novi model za određivanje promene entropije poluidealnog gasa primenom razlomljene temperaturne funkcije / New model for determining of change entropy of semi-ideal gas by using fractional temperature function
(Academy of Sciences and Arts of the Republic of Srpska, 2014)
Kod poluidealnog gasa, promena entropije ne može se odrediti preko srednjeg specifičnog toplotnog kapaciteta na način kao što se određuje promena unutrašnje energije i entalpije, odnosno razmenjena količina toplote. Uzimajući ...
