Synthesis, characterization and cytotoxicity of surface amino-functionalized water-dispersible multi-walled carbon nanotubes
(Elsevier Science Bv, Amsterdam, 2009)
Surface functionalization of multi-walled carbon nanotubes (MWCNTs), with amino groups via chemical modification of carboxyl groups introduced on the nanotube surface, using O-(7-azabenzotriazol-1-yl)-N, N,N',N'-tetramethyluronium ...
Influence of different iron powders on the friction properties of sintered friction materials based on iron
(Elsevier Science B.V., 2000)
The possibility of using iron powders of different morphological, chemical and physical properties as the bases of the metal matrix of the friction layer in sintered friction materials for dry friction under severe braking ...
Kinetics and mechanism of the reaction of substituted 4-pyrimidine carboxylic acids with diazodiphenylmethane in dimethylformamide
(Scientific Reviews Ltd., 2000)
Correlation of the data for the reaction of 11 substituted 4-pyrimidine carboxylic acids with diazodiphenylmethane (DDM) in dimethylformamide (DMF) with calculated atomic charges on the carboxylic group showed that the ...
Electrospray mass spectrometric studies of a potential antitumor drug and its analogous platinum(II) and platinum(IV) complexes with the ethylenediamine-N,N '-di-3-propanoato ligand and its dibutyl ester
(Springer Wien, Wien, 2009)
The electrospray mass spectrometric (ESI-MS) behavior of the complexes trans-dichloro(ethylenediamine-N, N'-di-3-propionato) platinum(IV), trans-dibromo(ethylenediamine-N, N'-di-3-propionato) platinum( IV), dichloro ...
The effect of temperature on strain-rate sensitivity in high strength Al-Mg alloy sheet
(Elsevier Science Sa, Lausanne, 2002)
Comprehensive experimental work performed to assess the temperature and strain-rate affected deformation behaviour of commercial AlMg6 type, 1.0 mm thick annealed sheet. Elevated temperature tension test performed at ...
Nanostructured sodium lithium niobate and lithium niobium tantalate solid solutions obtained by controlled crystallization of glass
(Elsevier Science Sa, Lausanne, 2005)
Transparent, nanostructured glass ceramics based on ferroelectric solid solutions of the type Na1-xLixNbO3 (in very narrow composition regions for x=0.12 and 0.93) and LiNb1-yTayO3 (y=0.5 unlimited solid solubility), can ...
Computational studies in the AlPO4-34 system
(Kluwer Academic Publ, Dordrecht, 2001)
The lattice energies of the as-synthesized fluoride-containing chabazite-like aluminophosphate (AlPO4-34F) and of the corresponding metal-substituted materials [MeAPO-34F, Me = Mn(II), Co(II), Ni(II)] have been calculated ...
The crystallisation of calcium phosphate glass containing vanadium oxide
(University of Chemistry and Technology, Prague, 2007)
The crystallisation behaviour of calcium phosphate glass containing vanadium oxide was studied. Glass with a molar ratio of [CaO]/[P2O5] = 1.13 and a V2O5 content of 8 mol.% was prepared for the experiments. The crystallisation ...
Influence of potential pulse conditions on the formation of honeycomb-like copper electrodes
(Journal of Electroanalytical Chemistry, 2009)
Electrodeposition of copper by pulsating overpotential (PO) regime in the hydrogen co-deposition range was examined by the determination of the average current efficiency of hydrogen evolution and by microscopic analysis ...
Synthesis and structure determination of a chain-like aluminophosphate obtained with 1,2-diaminopropane as the structure-directing agent
(Pergamon-Elsevier Science Ltd, Oxford, 2003)
Colorless plate-like crystals (AIPO-1,2DAP) crystallize from a clear 'AlPO4-1,2-diaminopropane' reaction system. The results of elemental, thermal and FTIR analyses give the following chemical formula: (NH4+)(1,2-H(2)DAP ...
