Mass spectrometric study of some 4-pyrimidine carboxylic acids
(Wiley, Hoboken, 2002)
Mass spectrometry has been applied in order to study the main fragmentation routes of some 4-pyrimidene carboxylic acids. Differences in fragmentation were caused by the nature of the substituent in position 2 of the ...
Osmotic coefficient of the ZnSO4(aq) at T=298.15 K
(Academic Press Ltd- Elsevier Science Ltd, London, 2002)
The osmotic coefficient of ZnSO4(aq) has been measured at T = 298.15 K by the iso-piestic method, in the range of molalities from 1.3 to 3.0 mol . kg(-1), with KCl(aq) as the reference solution. Experimental data of osmotic ...
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. ...
Electrochemical deposition and characterization of Zn-Co alloys and corrosion protection by electrodeposited epoxy coating on Zn-Co alloy
(Pergamon-Elsevier Science Ltd, Oxford, 2002)
Zn-Co alloys electrochemically deposited on steel under various deposition conditions were investigated. The influence of deposition current density, temperature and composition of deposition solution on the phase structure ...
Methanol electrooxidation on supported Pt and PtRu catalysts in acid and alkaline solutions
(Pergamon-Elsevier Science Ltd, Oxford, 2002)
The kinetics of methanol oxidation on supported 47.5 wt.% Pt and 54 wt.% Pt-Ru (with nominal Pt:Ru ratios of 2:3) catalysts are measured in 0.5 M H2SO4 and 0.1 NaOH at 295 and 333 K using thin-film rotating disk electrode ...
Predictive modeling of the mechanical properties of particulate hydroxyapatite reinforced polymer composites
(Wiley, Hoboken, 2002)
The influence of particle geometry and volume fraction on the mechanical properties of a hydroxyapatite (HAp) particulate reinforced polymer (poly-L-lactide and collagen) matrix composite was investigated through finite-element ...
Gain optimization in electrically pumped AlGaAs quantum cascade lasers
(Optical Soc Amer, Washington, 2002)
The design of the active region of a current-pumped quantum-cascade laser to achieve maximal gain is proposed. Starting with an arbitrary smooth potential, a family of isospectral Hamiltonians with a predefined energy ...
Comparative reflection and structural analyses of copper and zinc coatings electrodeposited from acid sulfate solutions without and with additives
(Elsevier, 2002)
Reflection and structural analyses of different copper and zinc coatings were performed. The coatings of copper obtained were from acid sulfate solutions in the absence and presence of thiourea. The coatings of zinc were ...
