Influence of the common varistor dopants (CoO, Cr2O3 and Nb2O5) on the structural properties of SnO2 ceramics
(Elsevier Science Inc, New York, 2004)
The influence of dopants commonly used in SnO2 varistor ceramics, such as CoO, Cr2O3 or Nb2O5, on the structural properties of SnO2 was investigated. Several SnO2-based ceramics containing only one of the dopants were ...
Determination of selected pesticides in environmental water by employing liquid-phase microextraction and liquid chromatography-tandem mass spectrometry
(Analytical and Bioanalytical Chemistry, 2010)
An optimised extraction and cleanup method for the analysis of pesticide in natural water samples is presented. Sixteen pesticides of different polarity and from the different chemical classes (organophosphates, triazines, ...
Immobilization of Candida rugosa lipase by adsorption onto biosafe meso/macroporous silica and zirconia
(Elsevier B.V., 2015)
Lipase from Candida rugosa was immobilized by adsorption onto laboratory prepared supports, silica SBA-15 and zirconia. The adsorption process was studied as a function of pH in terms of percent of adsorbed lipase, enzyme ...
Formation of dish-like holes and a channel structure in electrodeposition of copper under hydrogen co-deposition
(Elsevier, 2007)
Copper electrodeposition from acid sulfate solutions at an overpotential of 1000 mV, which is about 250 mV outside the plateau of the limiting diffusion current density, was examined by the determination of the average ...
A new setup for speed of sound measurements and experimental data for nanofluids Al2O3 or Ag with water or ethylene glycol
(Elsevier B.V., 2023)
The speed of sound of four different nanofluids consisting of Ag or Al2O3 nanoparticles and water or ethylene glycol base fluid is measured in the temperature range (298.15–343.15) K and at atmospheric pressure. One aim ...
Comparison of cavitation erosion behavior of cordierite and zircon based samples using image and morphological analyses
(Elsevier Science Bv, Amsterdam, 2018)
In this study the resistance of cordierite and zircon to the cavitation erosion was investigated with the aim of possible spreading their application. Cavitation erosion test was applied using standard ultrasonic vibratory ...
Experimental determination and modeling of excess molar volumes, viscosities and refractive indices of the binary systems (pyridine+1-propanol,+1,2-propanediol,+1,3-propanediol, and plus glycerol). New UNIFAC-VISCO parameters determination
(Academic Press Ltd- Elsevier Science Ltd, London, 2013)
Densities, viscosities and refractive indices of four binary systems consisting of pyridine with mono-, di-, and three- hydroxyl alcohols (1-propanol, 1,2-propanediol, 1,3-propanediol, and glycerol) were measured at eight ...
Seasonal water pricing using meteorological data: case study of Belgrade
(Elsevier Sci Ltd, Oxford, 2013)
The paper presents a model of seasonal water pricing (SWP) aimed primarily at diminishing excessive fresh water use in the city of Belgrade. Seasonal prices are determined on meteorological observations of the average ...
Nb-TiO2 supported platinum nanocatalyst for oxygen reduction reaction in alkaline solutions
(Pergamon-Elsevier Science Ltd, Oxford, 2011)
Platinum based nanocatalyst at home made Nb-TiO2 support was synthesized and characterized as the catalyst for oxygen reduction reaction in 0.1 mol dm(-3) NaOH, at 25 degrees C. Nb doped TiO2 catalyst support, containing ...
Synthesis and single-crystal structure analysis of a new layered zinc phosphate
(Pure and Applied Chemistry, 2005)
A new 2D zinc phosphate [H3NCH(CH3)CH 2NH3]2+0.75[COOH(CH 2)COOH]0.25 (Zn3P3O 11OH)2-* 0.5NH4+ consists of zinc phosphate layers, which are intercalated by diprotonated 1,2-diaminopropane, malonic acid, and NH4+ ions. The ...
