Electrochemical oxidation of iodide in aqueous solution
(Elsevier Science Sa, Lausanne, 2006)
Electrochemical oxidation of iodide on DSA (Ti/RuO2) anode was investigated in laboratory cell and semi-industrial electrochemical reactor. Anodic polarization curves in the laboratory cell were obtained in solutions ...
Substituent and solvent effects on the UV/Vis absorption spectra of 5-(4-substituted arylazo)-6-hydroxy-4-methyl-3-cyano-2-pyridones
(Elsevier, Amsterdam, 2004)
Absorption spectra of ten 5-(4-substituted arylazo)-6-hydroxy-4-methyl-3-cyano-2-pyridones have been recorded in fifteen solvents in the range 200-600 nm. The substituents at the phenyl nucleus are as follows: OH, OCH3, ...
Structural changes in the fabrication and ageing of PA66 textured yarn
(Wiley-VCH Verlag Gmbh, Weinheim, 2005)
The characterization of textured yarn is of great significance for both producers and final users. The influence of the texturing parameters (draw ratio and heater temperature) on the characteristics of the textured polyamide ...
Determination of metal content in some herbal drugs - Empirical and chemometric approach
(Elsevier, Amsterdam, 2005)
The concentrations of Cu, Zn, Mn, Fe, K, Ca, Mg, Al, Ba and B in 26 herbal drugs of special importance in phytopharmacywere studied. Flame atomic absorption and emission spectrometry (FAAS, FAES), as well as inductively ...
Antibacterial effect of silver nanoparticles deposited on corona-treated polyester and polyamide fabrics
(Wiley, Hoboken, 2008)
The possibility of using a corona treatment (electrical discharge at atmospheric pressure) for fiber surface activation, which can facilitate the loading of silver nanoparticles (NPs) from colloids onto the polyester (PES) ...
Obtaining crystals in a laboratory furnace
(Elsevier, Amsterdam, 2004)
A model of an air cooler (telescopic cold bridge) with a column of Tamman test tubes (telescopic test comb), installed in a laboratory tube furnace, for regulation and simultaneous crystallization tests at different ...
Bioreactor studies of native and tissue engineered cartilage
(IOS Press, Amsterdam, 2002)
Functional tissue engineering of cartilage involves the use of bioreactors designed to provide a controlled in vitro environment that embodies some of the biochemical and physical signals known to regulate chondrogenesis. ...
Adsorption of Pb2+, Cd2+ and Sr2+ ions onto natural and acid-activated sepiolites
(Elsevier Science Bv, Amsterdam, 2007)
The adsorption mechanisms of Ph2+, Cd2+ and Sr2+ ions on natural sepiolite and the influence of acid treatment on the adsorption capacity of sepiolite were investigated. The point of zero charge pH(pzc), is 7.4 +/- 0.1 for ...
Oak acorn, polyphenols and antioxidant activity in functional food
(Elsevier Sci Ltd, Oxford, 2006)
In this paper, are presented the results of physical and chemical investigations of differently treated samples of oak acorn. The aim of this investigation is to estimate the influence of thermal treatment on physical and ...
Quality control and thermal shock damage characterization of high-temperature ceramics by ultrasonic pulse velocity testing
(Wiley-Blackwell, Hoboken, 2007)
Ultrasonic pulse velocity testing was carried out to perform nondestructive quality control of refractory plates used as substrates in fast firing of porcelain whiteware. Two cordierite-mullite refractory compositions ...
