Antimicrobial activity of hybrid hydrogels based on poly(vinylpyrrolidone) containing silver / Antimikrobna aktivnost hibridnih hidrogelova na bazi poli(vinilpirolidona) koji sadrže srebro
(Association of Chemical Engineers of Serbia, 2010)
New hybrid hydrogels were prepared by radical copolymerization of 2-hydroxyethyl methacrylate, itaconic acid, poly(vinylpyrrolidone) and silver salt. FTIR spectroscopy has confirmed binding of silver particles in hydrogels. ...
The peculiarities of electrochemical deposition and morphology of Zn-Mn alloy coatings obtained from pyrophosphate electrolyte / Specifičnosti elektrohemijskog taloženja i morfologija Zn-Mn prevlaka dobijenih iz pirofosfatnog elektrolita
(Association of Chemical Engineers of Serbia, 2011)
The first successful attempt to electrodeposit Zn-Mn alloy coatings from alkaline bath was made only a few years ago. In this kind of solution, potassium pyrophosphate (K4P2O7) serves both as a complexing agent and as the ...
Silver/poly(N-vinyl-2-pyrrolidone) nanocomposites obtained by electrochemical synthesis / Srebro/poli(N-vinil-2-pirolidon) nanokompoziti dobijeni elektrohemijskom sintezom
(Association of Chemical Engineers of Serbia, 2011)
Silver/poly(N-vinyl-2-pyrrolidone) (Ag/PVP) nanocomposites were obtained by electrochemical reduction of Ag+ at a constant voltage, by in situ synthesis of silver nanoparticles inside a poly(N-vinyl-2-pyrrolidone) matrix, ...
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 ...
Tube for obtaining crystals in a laboratory furnaces
(Maik Nauka/Interperiodica/Springer, New York, 2011)
A model of an air-cooled tube with a number of movable plugs, installed in a laboratory tube furnace is presented. The setup (modular "crystallization shelf-comb") allows easy regulation and simultaneous crystallization ...
Correlation analysis of IR, 1H- and 13C-NMR spectral data of N-alkyl and N-cycloalkyl cyanoacetamides / Korelaciona analiza IR, 1H- i 13C-NMR spektalnih podataka N-alkil- i N-cikloalkilcijanoacetamida
(Association of the Chemical Engineers of Serbia, 2011)
Linear free energy relationships (LFER) were applied to the IR, 1H- and 13C- -NMR spectral data in N-alkyl and N-cycloalkyl cyanoacetamides. N-alkyl and N-cycloalkyl cyanocetamides were synthesized from corresponding amine ...
Simultaneous Crystallization Testing in a Laboratory Furnace
(American Laboratory, 2011)
The cooler allows easy regulation of simultaneous crystallization tests of different crystallization parameters and substances, with the purpose of obtaining crystals from a family of newly synthesized compounds with a ...
Ship waste quantities prediction model for the Port of Belgrade / Model za predviđanje količine otpada u Luci Beograd
(Association of the Chemical Engineers of Serbia, 2011)
This study focuses on the issues related to the waste management in river ports in general and especially in the port of Belgrade. Data on solid waste, waste oils, oily waters, gray water and black water have been collected ...
Characterization of non-starter lactic acid bacteria in traditionally produced home-made Radan cheese during ripening
(University of Belgrade, University of Novi Sad, 2011)
Two hundred thirteen non-starter lactic acid bacteria isolated from Radan cheese during ripening were identified with both a classical biochemical test and rep-PCR with (GTG)5 primer. For most isolates, which belong to the ...
Electrochemical synthesis and corrosion behavior of thin polyaniline film on mild steel, copper and aluminum / Sinteza i koroziono ponašanje polianilina na mekom čeliku, bakru i aluminijumu iz benzoatnih rastvora
(Association of Chemical Engineers of Serbia, 2011)
The electrochemical synthesis of polyaniline (PANI) on mild steel, aluminum and copper from the sodium benzoate solutions has been investigated. It has been shown that thin, highly adherent, polyaniline films on the ...
