Ni-(Ebonex-supported Ir) composite coatings as electrocatalysts for alkaline water electrolysis. Part I: Hydrogen evolution
(Elsevier, 2015)
The hydrogen evolution reaction (HER) was studied at electrodeposited Ni and Ni-(Ebonex/Ir) composite coatings in 1 mol dm-3 NaOH solution at 25 °C. The Ni-(Ebonex/Ir) coatings were electrodeposited from a nickel Watts ...
Ultrasound Extraction of Polyphenolic Compounds from Thymus serpyllum
(School of Chemical Engineering, Athens, 2015)
Aromatic plant species of family Lamiaceae are important medicinal plants because of their antioxidant, antimicrobial, antispasmodic, expectorant, stimulant and diuretic properties. In this study T. serpyllum herba was ...
Poly(urethane-dimethylsiloxane) copolymers displaying a range of soft segment contents, noncytotoxic chemistry, and nonadherent properties toward endothelial cells
(Wiley-Blackwell, Hoboken, 2015)
Polyurethane copolymers based on ,-dihydroxypropyl poly(dimethylsiloxane) (PDMS) with a range of soft segment contents were prepared by two-stage polymerization, and their microstructures, thermal, thermomechanical, and ...
Adsorpcija odabranih lekova i pesticida na rečnom sedimentu / Adsorption of selected pharmaceuticals and pesticides on river sediment
(Beograd : Srpsko hemijsko društvo, 2015)
Zagađujuće materije u životnoj sredini, poput lekova i pesticida ispoljavaju veliki afinitet da se akumuliraju u rečnim sedimentima, tako da rečni sedimenti mogu postati sekundarni izvor zagađenja. Cilj ovog rada bio je ...
Antimikrobna aktivnost bagremovog meda
(Технолошки факултет, Лесковац, 2015)
Antibakterijsko, antifungicidno i antivirusno dejstvo meda poznato je od davnina i najvećim delom potiče od vodonik-peroksida, koji nastaje aktivnošću enzima glukoza-oksidaza koji pčele izlučuju u med. Pored vodonik-peroksida, ...
The novel approach to the biomonitor survey using one- and two-dimensional Kohonen networks
(Springer, Dordrecht, 2015)
To compare the applicability of the leaves of horse chestnut (Aesculus hippocastanum) and linden (Tilia spp.) as biomonitors of trace element concentrations, a coupled approach of one-and two-dimensional Kohonen networks ...
Quality, sources and balancing of iron and steel scrap / Kvalitet, izvori i bilansiranje otpadaka gvožđa i čelika
(Savez inženjera i tehničara Srbije, Beograd, 2015)
Besides iron ore, the main raw material of iron and steel production is steel scrap. This paper presents the quality and sources of creation the iron and steel scrap and estimation of their creation in the future. The ...
Mechanochemically assisted solid-state and citric acid complex syntheses of Cu-doped sodium cobaltite ceramicsh
(Elsevier Science Sa, Lausanne, 2015)
In the last decade, the sodium cobaltite ceramic became a promising candidate for potential thermoelectric applications, because of its large thermopower and low resistivity. In this work, polycrystalline samples of ...
Surface characterization of mesoporous carbon cryogel and its application in arsenic (III) adsorption from aqueous solutions
(Elsevier, 2015)
Resorcinol-formaldehyde (RF) cryogels were synthesized by sol-gel polycondensation of resorcinol with formaldehyde and freeze-drying was carried out with t-butanol. Carbon cryogel (CC) was obtained by pyrolyzing RF cryogels ...
Estimation of GHG emission in Serbia for period 1995-2013 using recurent neural networks / Emisije gasova staklene bašte u Srbiji za period 1995-2013. godina primenom rekurentnih neuronskih mreža
(Naučno-stručno društvo za zaštitu životne sredine Srbije - Ecologica, Beograd, 2015)
The aim of this work was to create an ANN model for the prediction of GHG emissions in the Republic of Serbia in the period 1995-2013. Because of the lack of GHG emission data and inputs for Serbia, the ANN model was ...
