A fracture mechanics approach to thermal shock investigation in alumina-based refractory
(9th International Conference on Multiscale and Functionally Graded Materials, FGM IX, 2008)
The thermal shock behavior of large grain size, alumina-based refractories was investigated experimentally using a standard water quench test. A mathematical model was employed to simulate the thermal stability behavior. ...
Corrosion stability of epoxy coatings on aluminum pretreated by vinyltriethoxysilane
(Pergamon-Elsevier Science Ltd, Oxford, 2008)
The electrochemical and transport properties and adhesion of epoxy coatings electrodeposited on aluminum pretreated by vinyltriethoxysilane (VTES) were investigated during exposure to 3% NaCl. The VTES films were deposited ...
Membrane interactions of ternary phospholipid/cholesterol bilayers and encapsulation efficiencies of a RIP II protein
(Elsevier Science Bv, Amsterdam, 2008)
Membrane interactions of liposomes of ternary phospholipid/cholesterol bilayers are investigated. These interactions lead to discoidal deformations and regular aggregations and are strongly enhanced by the presence of ...
Extraction of hyperforin and adhyperforin from St. John's Wort (Hypericum perforatum L.) by supercritical carbon dioxide
(Elsevier, Amsterdam, 2008)
St. John's Wort (Hypericum perforatum L.) was extracted with supercritical carbon dioxide (SC CO2) under 10, 15 and 20 MPa and at 313 and 323 K. The influence Of SC CO2 density (400-800 kg/m(3)) was examined with respect ...
Polyaniline as possible anode materials for the lead acid batteries
(Elsevier Science Bv, Amsterdam, 2008)
Electrochemically formed thin film polyaniline (PANI) anode and lead dioxide (PbO2) cathode, obtained from sulfuric acid solution, for potential applications as electrode materials in PANI vertical bar H2SO4 vertical bar ...
Double-layer bioactive glass coatings obtained by pulsed laser deposition
(Trans Tech Publications Ltd, Durnten-Zurich, 2008)
Pulsed laser deposition was used to obtain functionally graded bioactive glass coatings on titanium substrates. An UV KrF* (lambda=248 nm, tau gt 7 ns) excimer laser was used for the multi-pulse irradiation of the targets. ...
Hindered, 1,1-disubstituted monomers. Chain transfer to benzene in the radical polymerisation of di-n-butylitaconate
(Pergamon-Elsevier Science Ltd, Oxford, 2008)
The transfer constant to benzene in the radical polymerisation of di-n-butyl itaconate, DBI, was measured at 60 degrees C and found to have the value of 2.2 x 10(-3). This value is surprisingly high considering that benzene ...
The electrochemical behavior of erythromycin A on a gold electrode
(Pergamon-Elsevier Science Ltd, Oxford, 2008)
The reactivity of erythromycin (pure) was investigated on a gold electrode in neutral electrolyte by cyclic voltammetry. The resulting structural changes were observed with HPLC and FTIR spectroscopy by analyzing the bulk ...
Thermal shock behavior of alumina based refractories: Comparison with the mechanical data and thermal stability behavior prediction
(Belgian Ceramic Soc, Mons, 2008)
The thermal shock behavior of a large grain size alumina based refractories were investigated both experimentally, using standard procedure of water quench test and using mathematical calculation method for determining the ...
Interpretative optimization and artificial neural network modeling of the gas chromatographic separation of polycyclic aromatic hydrocarbons
(Elsevier, Amsterdam, 2008)
An interpretative strategy (factorial design experimentation + total resolution analysis + chromatogram simulation) was employed to optimize the separation of 16 polycyclic aromatic hydrocarbons (PAHs) (naphthalene, ...
