Estimate of Si3N4 diffusion into Cu based filler metal
(Elsevier Science Ltd, 2000)
The diffusion phenomena occurring at the boundary between Si3N4 and active Cu based filler metal during Si3Nn/metal joining are discussed as a part of the general theory of reaction layer growth. The mechanism of reaction ...
Lipase-catalyzed synthesis of biodiesel in solvent-free system with different acyl acceptors
(Elsevier Science Bv, Amsterdam, 2009)
Finite element modeling of mechanical properties of particulate composite biomaterials
(Proceedings of the fourth Yugoslav Materials Research Society Conference (YUCOMAT IV), 2002)
The influence of inclusion geometry and volume fraction on stiffness behavior of a particle hydroxyapatite filled polymer (poly-L-lactide and collagen) matrix composite was investigated by finite element. analysis. The ...
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 ...
Corrosion behaviour of epoxy coatings electrodeposited on galvanized steel and steel modified by Zn-Ni alloys
(Elsevier Science Sa, Lausanne, 2000)
The electrochemical and transport properties and thermal stability of epoxy coatings electrodeposited on hot-dip galvanized steel and steel modified by Zn-Ni alloys were investigated during exposure to 3% NaCl solution. ...
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. ...
Densities, viscosities, and surface and interfacial tensions of the ternary mixture water plus ethyl butyrate plus methanol at 303.15
(Amer Chemical Soc, Washington, 2003)
The excess molar volumes, V-E, viscosity deviations, Deltaeta, and excess surface tensions were calculated from the measured density, viscosity, and surface tension values, a, over the whole miscibility composition range ...
The Candida rugosa lipase catalyzed synthesis of amyl isobutyrate in organic solvent and solvent-free system: A kinetic study
(Elsevier, Amsterdam, 2006)
The Candida rugosa lipase catalyzed esterification of butyric acid with amyl alcohol in isooctane and in solvent-free system was studied. Nearly complete conversion ( gt 95%) of substrates was achieved using low enzyme ...
An inverse gas chromatography study of the adsorption of organics on nickel- and copper-hexacyanoferrates at zero surface coverage
(Academic Press Inc Elsevier Science, San Diego, 2002)
The surface properties of Ni and Cu hexacyanoferrates were investigated by the inverse gas chromatography method. Retentions of 10 organic compounds were measured at zero surface coverage in the temperature range 80 to 95 ...
Surface properties of HAP particles obtained by hydrothermal decomposition of urea and calcium-EDTA chelates
(Proceedings of the 15th International Symposium on Ceramics in Medicine; The Annual Meeting of the International Society for Ceramics in Medicine, 2003)
In this paper surface properties of calcium-hydroxyapatite, synthesized by modified hydrothermal reaction of urea and Ca(EDTA)(2-) in phosphate solutions, as well as the dependence of calcium hydroxyapatite dispersion ...
