Trans- and cis-resveratrol concentration in wines produced in Serbia / Koncentracija trans- i cis-rezveratrola u vinima proizvedenim u Srbiji
(Serbian Chemical Soc, Belgrade, 2008)
Resveratrol, which occurs in two isomeric forms, trans and cis, is a phytoalexin with numerous pharmacological activities, such as anti-cancer, antiviral, neuroprotective and anti-aging. Red wine is the main source of the ...
Low concentration volatile organic pollutants removal in combined adsorber-desorber-catalytic reactor system / Integrisani sistem adsorber-desorber-katalitički reaktor za uklanjanje malih koncentracija organskih zagađujućih materija
(Association of Chemical Engineers of Serbia, 2008)
The removal of volatile organic compounds (VOCs) from numerous emission sources is of crucial importance due to more rigorous demands on air quality. Different technologies can be used to treat the VOCs from effluent gases: ...
The ionic equilibrium in the CuSO4-H2SO4-H2O system and the formation of the honeycomb-like structure during copper electrodeposition / Jonska ravnoteža u sistemu CuSO4-H2SO4-H2O i formiranje strukture pčelinjeg saća elektrohemijskim taloženjem bakra
(Serbian Chemical Society, 2008)
The ionic equilibrium of the species in the CuSO4-H2SO4-H2O system was employed to systematize the conditions of copper electrodeposition leading to the formation of the honeycomb-like structure. The reason why CuSO4 ...
Electrocatalytic properties and stability of titanium anodes activated by the inorganic sol-gel procedure / Titanske anode aktivirane oksidnom prevlakom dobijenom sol-gel postupkom
(Serbian Chemical Society, 2008)
The properties of activated titanium anodes, RuO2-TiO2/Ti and RuO2--TiO2-IrO2/Ti, prepared from oxide sols by the sol-gel procedure, are reviewed. RuO2 and TiO2 sols were synthesized by forced hydrolysis of the corresponding ...
Photoelectrochemical properties of sol-gel obtained titanium oxide / Fotoelektrohemijska svojstva titan-oksida dobijenog sol-gel postupkom
(Serbian Chemical Society, 2008)
The photoelectrochemical properties of a sol-gel prepared titanium oxide coating applied onto a Ti substrate were investigated. The oxide coating was formed from an inorganic sol thermally treated in air at 350°C. The ...
Analysis of amphetamines illegally produced in Serbia / Анализа амфетамина илегално произведеног у Србији
(Belgrade : Serbian Chemical Society, 2008)
Forensic practice in the Republic of Serbia faced the illegal production of amphetamine for the first time in 2003. This paper presents the results of the chemical characterization of 32 batches of amphetamine samples from ...
Characterization of type III kerogen from Tyrolean shale (Hahntennjoch, Austria) based on its oxidation products / Karakterizacija kerogena tipa III Tirolskog škriljca (Hahntennjoch, Austrija) zasnovana na njegovim oksidacionim proizvodima
(Serbian Chemical Society, 2008)
A 29-step alkaline permanganate degradation of type III kerogen from Tyrolean (Hahntennjoch, Austria) oil shale was performed. A high yield of oxidation products was obtained (93.7 % relative to the original kerogen): 0.5 ...
Performances of continuous dryer with inert medium fluidized bed / Performanse kontinualne sušnice sa fluidizovanim slojem inertnih čestica
(Association of Chemical Engineers of Serbia, 2008)
A fluid bed dryer with inert particles represents a very attractive alternative to other drying technologies according to the main efficiency criteria, i.e. specific water evaporation rate, specific heat consumption and ...
Prevention and control of dimethylamine vapors emission: Herbicide production plant
(Association of the Chemical Engineers of Serbia, 2008)
The widely used herbicide, dimethylamine salt of 2,4-dichlorophenoxy acetic acid (2,4-D-DMA), is usually prepared by mixing a dimethylamine (DMA) aqueous solution with a solid 2,4-dichlorophenoxy acetic acid (2,4-D). The ...
Surface roughness of ultra-thin silver films sputter deposited on a glass
(Wiley, 2008)
Silver was sputter deposited on a glass with a thin film thickness ranging from 10 to 80 nm. Scanning tunnelling microscopy was used to study the morphology of the obtained Ag-glass surfaces and to estimate the surface ...
