Methyl methacrylate and acrylamide crosslinked macroporous copolymers
(Journal of Applied Polymer Science, 2004)
In this work the synthesis of a crosslinked macroporous copolymer was effected from methyl methacrylate and acrylamide. The synthesis process began with emulsion prepolymerization, followed by sol-gel copolymerization until ...
Dielectric and piezoelectric properties of the mechanochemically prepared PZT ceramics
(Kluwer Academic Publishers, 2004)
Mechanochemical synthesis was applied to obtain nanocrystalline powders of composition Pb(Zr0.52Ti0.48)O-3 (PZT). Milling was performed in a planetary ball mill using vials and balls made of zirconia or steel-in order to ...
Electrocatalytic behaviour of MoPt3 intermetallic phase for hydrogen evolution in acid solution
(Ecole Polytechnique de Montreal, 2004)
Metallurgicaly prepared MoPt3 intermetallic compound has been investigated as electrocatalyst for the cathodic evolution of hydrogen (HER) in 0.5 mol dm-3 HClO4 solution at 298 K. The HER on activated and non-activated ...
Mechanochemical synthesis of gamma-Bi2O3
(Amsterdam : Elsevier, 2004)
A series of gamma-Bi2O3 phases doped with Zn, Si, Pb and Fe was prepared by mechanochemical treatment of corresponding oxide mixtures with a nominal composition 6Bi(2)O(3) (.) MOx (MOx = ZnO, SiO2, PbO) and 12Bi(2)O(3) (.) ...
Synthesis of new hyperbranched urethane-acrylates and their evaluation in UV-curable coatings
(Elsevier Science Sa, Lausanne, 2004)
Three series of hyperbranched urethane-acrylates (HB-UA), based on aliphatic hyperbranched polyesters and polyethyleneglycol acrylate, were prepared and evaluated for use in UV-curable coatings. UV-curing kinetics were ...
Estimation of elastic properties of a particulate polymer composite using a face-centered cubic FE model
(Elsevier, Amsterdam, 2004)
A three-dimensional (31)) finite element (FE) unit cell model is applied to studies on the elastic properties of ceramic spherical particle-polymer composite. In this model, hydroxyapatite particles (HAp) are assumed to ...
Dynamic calibration of a sensor gas calorimeter for measurement of heat generation rates during kinetic of adsorption experiments
(Elsevier, Amsterdam, 2004)
A procedure for dynamic calibration of a sensor gas calorimeter, resulting with a calibration transfer function, instead with a calibration line, is presented. The main factors influencing the calibration transfer function ...
Thermodynamic modeling of vapor-liquid equilibria and excess properties of the binary systems containing diethers and n-alkanes by cubic equation of state
(Korean Institute Chemical Engineers, Seoul, 2004)
A comparison of the performances of two different approaches of cubic equations of state models, based on a classical van der Waals and mixing rules incorporating the G(E) equation, was carried out for correlation of ...
Thermal behaviour of mixed ligand Co(II), Ni(II) and Cu(II) complexes containing terephthalate ligands
(Elsevier, Amsterdam, 2004)
Thermal behaviour of a series of ternary Co(II), Ni(II) and Cu(II) complexes with terephthalate ion and some aromatic diamines has been studied by thermogravimetric and differential scanning calorimetric techniques. ...
Optical fibers with composite magnetic coating for magnetic field sensing
(Elsevier Science Bv, Amsterdam, 2004)
The investigated system for optical fiber sensor was multi-mode optical fiber with magnetic composite coating. Polymer component of composite coating was poly (ethylene-co-vinyl acetate)-EVA, and the magnetic component was ...
