Study of the kinetics and the influence of Bi-irr, on formic acid oxidation at Pt2RU3/C
(Pergamon-Elsevier Science Ltd, Oxford, 2007)
Electrochemical oxidation of HCOOH in H2SO4 and HCIO4 solutions was examined on thin film Pt2RU3/C electrode. XRD pattern revealed that Pt2RU3 alloy consisted of the solid solution of Ru in Pt and the small amount of Ru ...
Preliminary characterization of lactic acid bacteria isolated from Zlatar cheese
(Wiley, Hoboken, 2007)
Aims: Isolation, characterization and identification of lactic acid bacteria (LAB) from artisanal Zlatar cheese during the ripening process and selection of strains with good technological characteristics. Methods and ...
Mathematical modeling of insulin sorption by ion-exchange fiber
(John Wiley & Sons Inc, Hoboken, 2007)
The objective of this study was to investigate the phenomenon and kinetics of insulin chemisorption by cation-exchange acrylic fibers, as well as the development of theoretical modeling of the chemisorption process. Change ...
Multiphysics modeling of electric-swing adsorption system with in-vessel condensation
(Springer, Dordrecht, 2007)
Mathematical modeling of an Electric-Swing Adsorption (ESA) system (adsorption cycle with electrothermal desorption step, performed by direct heating of the adsorbent particles by passing electric current through them), ...
Bioactive glass and hydroxyapatite thin films obtained by pulsed laser deposition
(Elsevier, Amsterdam, 2007)
Bioactive glass (BG), calcium hydroxyapatite (HA), and ZrO2 doped HA thin films were grown by pulsed laser deposition on Ti substrates. An UV KrF* (lambda = 248 nm, tau gt = 7 ns) excimer laser was used for the multi-pulse ...
XPS and contact angle study of cotton surface oxidation by catalytic bleaching
(Elsevier Science Bv, Amsterdam, 2007)
Surface chemistry and wetting properties of cotton fibres as affected by catalytic bleaching have been investigated. Two types of cotton fabric have been analysed: the regular and a model cotton fabric. In the regular - ...
Synthesis and settings behavior of alpha-TCP from calcium deficient hyroxyapatite obtained by hydrothermal method
(Natl Inst Optoelectronics, Bucharest-Magurele, 2007)
The aim of this work is the investigation of alpha-tricalcium-phosphate (alpha-TCP) formation from calcium-deficient hydroxyapatite (CDHAP), synthesized by hydrothermal method from CaCl2, EDTA, NaH2PO4 center dot 2H(2)O ...
Swelling and thermodynamic studies of temperature responsive 2-hydroxyethyl methacrylate/itaconic acid copolymeric hydrogels prepared via gamma radiation
(Pergamon-Elsevier Science Ltd, Oxford, 2007)
The copolymeric hydrogels based on 2-hydroxyethyl methacrylate (HEMA) and itaconic acid (IA) were synthesized by gamma radiation induced radical polymerization. Swelling and thermodynamic properties of PHEMA and copolymeric ...
Carbon-13 substituent chemical shifts in N-1-p-substituted phenyl-5-methyl-4-carboxy uracils
(Elsevier Science Bv, Amsterdam, 2007)
The C-13 NMR chemical shifts of seven N-1-p-substituted phenyl-5-methyl-4-carboxy uracils have been measured in deuterated dimethyl sulfoxide (DMSO-d sigma). The correlation analysis for the substituent-induced chemical ...
Influence of composition of the magnetic composite coating on the performance of the optical fiber magnetic field sensing element
(Natl Inst Optoelectronics, Bucharest-Magurele, 2007)
The optical fiber magnetic sensing element (OFMSE) based on the optical fiber coated with composite coating polymer-magnetic powder has been already introduced in magnetic field sensing. In this research, the rapid quenched ...
