The effect of the composition of the dispersing medium of oxide sols on the electrocatalytic activity of sol-gel obtained RuO2-TiO2/Ti anodes / Uticaj sastava disperzne sredine oksidnih solova na elektrokatalitičku aktivnost RuO2-TiO2/Ti anoda dobijenih sol-gel postupkom
(Serbian Chemical Society, 2001)
The influence of the addition of methanol, ethanol, 1-propanol and 2-propanol to the dispersing medium of a mixture of RuO2 and TiO2 sols on the electrochemically active surface area for proton exchange, as well as on the ...
Alkylation of carbonyl compounds in the TiCl4-promoted reaction of trimethylsilyl enol ethers with epoxides
(Oxford : Pergamon-Elsevier Science Ltd, 2001)
Titanium tetrachloride promoted reaction of trimethylsilyl enol ethers with ethylene oxide affords homoaldol type products in moderate/good yields. Monosubstituted epoxides react regioselectively: the nucleophilic attack ...
A time effect in the early stages of a surface oxidation of a Pt(111) plane in alkaline solution / Vremenski efekat u oksidaciji Pt(111) površine u alkalnoj sredini
(Serbian Chemical Society, 2001)
A time effect in the early stages of surface oxidation of a Pt(111) plane in 0.1 M NaOH solution was studied by examining the reduction parts of the j/E profile recorded after holding the potential for various times at ...
The influence of inert component on the morphology and porosity parameters of macroporous poly (4-vinyl pyridine-co-ethylene glycol dimethacrylate) / Uticaj sastava i udela inertne komponente na morfologiju i parametre porozne strukture makroporoznog kopolimera 4-vinilpiridina i etilenglikoldimetakrilata
(Association of Chemical Engineers of Serbia, 2001)
In this study, the influence of the type and content of inert component in the reaction mixture on the properties of crosslinked macroporous copolymers of 4-vinyl pyridine and ethylene glycol dimethacrylate, poly ...
Trace and major element pollution originating from coal ash suspension and transport processes
(Elsevier, 2001)
Coal ash obtained by coal combustion in the “Nikola Tesla A” power plant in Obrenovac, near Belgrade, Yugoslavia, is mixed with water of the Sava river and transported to the dump. In order to assess pollution caused by ...
Low-molecular-weight protease inhibitors of microbial origin / Niskomolekulski inhibitori proteaza mikrobnog porekla
(Srpsko hemijsko društvo, Beograd, 2001)
We have witnessed an explosion of informations about properties, also mode of action and regulation of proteases from the metalloproteases at the cell surface to the AIDS protease. Protease inhibitors have a great importance ...
Investigation of mixed D(2)/5-HT(1A) activity of N-heteroarylmethyl-N-phenylpiperazines, N-heteroarylethyl-N-phenylpiperazines and N-heteroarylpropyl-N-phenylpiperazines
(Govi-Verlag Pharmazeutischer Verlag Gmbh, Eschborn, 2001)
Eight novel N-heteroarylalkyl-N-phenylpiperazines have been synthesized, chemically characterized and evaluated for in vitro binding affinity at the dopamine and serotonin receptors. Synaptosomal membranes of fresh bovine ...
Parthenolide from the aerial parts of Tanacetum larvatum
(Oxford : Pergamon-Elsevier Science Ltd, 2001)
The genus Tanacetum L. comprises ca 150 species that commonly occur in Europe from the Mediterranean to Persia. Tanacetum larvatum (Gris.) Kanitz, the examination of which is reported, is distributed on elevated rocky ...
The effect of diffusion on the impulse response of RCE detector
(IEEE Photonics Technology Letters, 2001)
We present a theory which demonstrates how the diffusion of photogenerated carriers affects the impulse response of a resonant-cavity enhanced photodetector (RCE). Analytic expressions for carrier densities and short-circuit ...
A brief review of microwave photonic band-gap (PGB) structures
