Antimicrobial and Photocatalytic Abilities of Ag2CO3 Nano-Rods
(Wiley-V C H Verlag Gmbh, Weinheim, 2017)
The rod-like Ag2CO3 particles (2-4 3 0.3-0.6 mm, length 3 diameter) were synthesized in water by the precipitation reaction between AgNO3 and NaHCO3 in the presence of polyvinylpyrrolidone. The X-ray diffraction analysis ...
Phase composition and magnetic properties of multiphase melt-spun Nd 4.3Fe76.2B19.5alloy
(Materials Science Forum, 2007)
Phase transformations and magnetic properties of multiphase Nd 4.5Fe76.2B19.5 alloy were investigated in the temperature range of heat treatment 600-700°C. The influence of different heat treatment regimes was observed by ...
TLC Retention Behavior of Brodifacoum, Bromadiolone, and Coumatetralyl and their Impurities on Different Adsorbents
(Akademiai Kiado Zrt, Budapest, 2009)
The chromatographic behavior of three biocidal technical materials, rodenticide active ingredients brodifacoum, bromadiolone, and coumatetralyl, and impurities present in the technical material was investigated by both ...
Analysis of Tea for Metals by Flame and Graphite Furnace Atomic Absorption Spectrometry with Multivariate Analysis
(Taylor and Francis Inc., 2017)
The concentrations of iron, zinc, manganese, copper, chromium, nickel, lead, arsenic, and cadmium were determined using flame and graphite furnace atomic absorption spectrometry in nine herbal tea samples. Hawthorn, yarrow, ...
Determination of all pK(a) values of some di- and tri-carboxylic unsaturated and epoxy acids and their polylinear correlation with the carboxylic group atomic charges
(Scientific Reviews Ltd., 2003)
For a series of seven unsaturated and seven epoxy di- and tricarboxylic acids, pK(a)(a) values were determined potentiometrically in aqueous media at 25 degreesC and an ionic strength of 0.1 M (NaCl). The thermodynamic ...
Study of supported Pt and PtRu catalysts in methanol and formic acid oxidation
(Trans Tech Publications Ltd, Switzerland, 2004)
The kinetics of methanol and formic acid oxidation on supported Pt and Pt2Ru3 catalysts are measured in 0.5 M H2SO4 at ambient temperature using thin-film rotating disc electrode (RDE) method. Both catalysts are characterized ...
Geochemical and Statistical Methods in the Evaluation of Trace Elements Contamination: an Application on Canal Sediments
(Hard, Olsztyn 5, 2011)
The contamination levels of V, Cr, Ni, Cu, Zn, Cd, and Pb in canal sediments (Danube alluvial formation) were assessed to evaluate environmental quality and potential contamination. Results indicate that silicates and ...
Mass transfer and fluid flow visualization in packed and fluidized beds by the adsorption method
(Maik Nauka/Interperiodica/Springer, New York, 2009)
Mass transfer coefficient (j D ) between fluid and column wall in liquid packed and fluidized beds of spherical inert particle has been studied experimentally using adsorption method. Experiments were conducted in column ...
Benthic diatoms of the Vrla River (Serbia) and their application in the water ecological status assessment
(Walter De Gruyter Gmbh, Berlin, 2016)
Epilithic diatoms from the Vrla River (Serbia) have been used to assess the ecological status of water. A total of 227 diatom taxa belonging to 50 genera were identified in the Vrla River during six research seasons with ...
