Microwave synthesis and characterization of Pt and Pt-Rh-Sn electrocatalysts for ethanol oxidation / Mikrotalasna sinteza i karakterizacija Pt i Pt-Rh-Sn katalizatora za oksidaciju etanola
(Serbian Chemical Society, Belgrade, 2011)
Carbon-supported Pt and Pt-Rh-Sn catalysts were synthesized by the microwave-polyol method in ethylene glycol solution and were investigated in the ethanol electro-oxidation reaction. The catalysts were characterized in ...
Characterisation of surface oxygen groups on different carbon materials by the Boehm method and temperature-programmed desorption / Karakterizacija površinskih kiseoničnih grupa različitih karbonskih materijala Bemovom (Boehm) metodom i temperaturski programiranom desorpcijom
(Serbian Chemical Society, Belgrade, 2011)
The surface characteristics of different carbon materials: activated carbon, carbon felt, glassy carbon and a porous carbon monolith were investigated. The specific surface area was examined by the BET method with N2 ...
The apparent density as a function of the specific surface of copper powder and the shape of the particle size distribution curve
(Serbian Chemical Society, 2003)
The relation between the specific surface and apparent density of copper powders electrodeposited from acid copper sulphate solutions is established. It is shown that the apparent density is inversly proportional to the ...
Microstructure and corrosion behaviour of Zn-Co alloys deposited from three different plating baths / Mikrostruktura i koroziono ponašanje Zn-Co legura taloženih iz sulfatnog i hloridnih rastvora
(Serbian Chemical Society, Belgrade, 2011)
The effects of plating baths of different composition on the micro- structure and corrosion stability of Zn-Co alloy coatings were studied. Zn-Co alloys with the same Co content were deposited from chloride plating baths ...
Structure-activity relationships of 3-substituted-5,5-diphenylhydantoins as potential antiproliferative and antimicrobial agents / Uticaj strukture na antiproliferativnu i antibakterijsku aktivnost 3-supstituisanih-5,5-difenilhidantoina
(Serbian Chemical Society, Belgrade, 2011)
A series of twelve 3-substituted-5,5-diphenylhydantoins was synthesized, including some whose anticonvulsant activities have already been reported in the literature. Their antiproliferative activities against HCT-116 human ...
Arsenic removal from water using low-cost adsorbents - a comparative study / Pregled savremenih metoda za uklanjanje arsena iz vode
(Serbian Chemical Society, Belgrade, 2011)
Inorganic arsenic removal from water using low-cost adsorbents is presented in this paper. Selective removal of As(III) and As(V) from water was performed with natural materials (zeolite, bentonite, sepiolite, pyrolusite ...
Production of lipase from Pseudozyma aphidis and determination of the activity and stability of the crude lipase preparation in polar organic solvents / Proizvodnja lipaze iz Pseudozyma aphidis i utvrđivanje aktivnosti i stabilnosti lipaze u polarnim organskim rastvaračima
(Serbian Chemical Society, Belgrade, 2011)
The production of lipase from Pseudozyma aphidis (DSM 70725) was determined in six different media. The highest lipase production was observed in a medium with glucose as the sole carbon source, and yeast extract and sodium ...
Corrosion of an austenite and ferrite stainless steel weld / Korozija zavarenog spoja austenitnog i feritnog nerđajućeg čelika
(Serbian Chemical Society, Belgrade, 2011)
Dissimilar metal connections are prone to frequent failures. These failures are attributed to the difference in the mechanical properties across the weld, the coefficients of thermal expansion of the two types of steels ...
Electrochemical synthesis of silver nanoparticles in poly(vinyl alcohol) solution / Elektrohemijska sinteza nanočestica srebra u rastvoru poli(vinil alkohola)
(Serbian Chemical Society, Belgrade, 2013)
In this work, silver/poly(vinyl alcohol), Ag/PVA, colloidal dispersions were obtained by electrochemical reduction of Ag+. The electrochemical synthesis of silver nanoparticles in aqueous solutions of 5 and 10 wt. % PVA, ...
