Thermal expansion coefficients, a. excess thermal expansion coefficients, alpha(E), isothermal coefficients of pressure excess molar enthalpy, (partial derivative H(E)/partial derivative p)T(,x), partial molar volumes, (V) ...
Obtaining of the antioxidants by supercritical fluid extraction / Izolovanje antioksidanasa postupkom natkritične ekstrakcije
(Association of Chemical Engineers of Serbia, 2011)
One of the important trends in the food industry today is demand for natural antioxidants from plant material. Synthetic antioxidants such as butylated hydroxytoluene (BHT), and butylated hydroxyanisole (BHA) are now being ...
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 ...
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 ...
