Thermal diffusivity of NTC lasers obtained by photoacoustic technique
(Emerald, 2004)
The thermal diffusivity of thick film NTC layers based on a metal oxide powder mixture was measured at room temperature by the photoacoustic (PA) technique. The powder mixture was composed of MnO (60 percent), CoO (32 ...
Determination of silanol end groups in polysiloxanes obtained from dimethyldichlorosilane hydrolysate (DDSH) / Odredjivanje silanolnih krajnjih grupa u polisiloksanima dobijenim iz dimetildihlorsilan hidrolizata (ddsh)
(Serbian Chemical Society, 2006)
Dimethyldichlorosilane hydrolysate, DDSH, the linear part of which contains SiOH end groups, can be used in the preparation of difunctionally terminated (any end groups other than SiOH) polysiloxanes via equilibration ...
Anticorrosion activity of 2-thiоhуdantoin–Shiff base derivatives for mild steel in 0.5 M HCl / Антикорозиона активност деривата шифових база 2-тиохидантоина за меки челик у 0,5 m hcl
(Serbian Chemical Society, 2022)
Several 2-thiohydаntоin–Shiff base derivatives were prepared as ecofriendly
corrosion inhibitors for mild steel in acid environment. Their anticorrosion
properties were studied on mild steel in 0.5 M HCl solution as ...
Synthesis, antioxidant and antimicrobial activity of carbohydrazones
(Serbian Chemical Society, 2017)
Fourteen mono- and bis-carbohydrazone ligands have been synthesized and characterized. Antioxidant activity of the substances was investigated together with possible (E)/(Z) isomerization, and explained on the most active ...
Cu(II) immobilization onto a one-step synthesized poly(4-vinylpyridine-co-ethylene glycol dimethacrylate) resin: Kinetics and XPS analysis
(Association of Chemical Engineers of Serbia, 2016)
Synthesis of an unconventional resin based on 4-vinylpyridine (4-VP) and its Cu(II) sorption behavior were studied. Three samples of macroporous crosslinked poly(4-vinylpyridine-co-ethylene glycol dimethacrylate) (P4VPE) ...
Fluctuations of the number of adsorbed micro/nanoparticles in sensors for measurement of particle concentration in air and liquid environments / Fluktuacije broja adsorbovanih mikro/nanočestica kod senzora za merenje koncentracije čestica u vazduhu i tečnim sredinama
(Association of the Chemical Engineers of Serbia, 2015)
A theoretical model of fluctuations of the number of adsorbed micro/nanoparticles in environmental sensors operating in air and liquids is presented, taking into account the effects of the mass transfer processes of the ...
Electrochemical properties of carbonized bentonite / Elektrohemijska svojstva karbonizovanih bentonita
(Serbian Chemical Society, 2022)
Organomodified bentonites were obtained by modification of bentonite clay from local mine Bogovina, with four different alkylammonium ions in the amounts that correspond to cation exchange capacity. Carbonized bentonites, ...
Bioavailability and catalytic properties of copper and iron for Fenton chemistry in human cerebrospinal fluid
(Taylor & Francis Group, 2010)
A breakdown in homeostasis of redox-active metals represents an important factor for neurodegeneration. We have used EPR spectroscopy and BMPO spin-trap to investigate the catalytic properties and ligand modulation of redox ...
Voltammetric and Quantum Investigation of Selected Succinimides
(Esg, Belgrade, 2018)
A series of succinimide derivatives were studied using the cyclic and square wave voltammetry. Density function theory was used in order to determinate which of the structural parameters influence the electrochemical ...
