Deformation pattern and strain hardening in a highly textured 8090 Al-Li alloy sheet
(Elsevier Science Sa, Lausanne, 2000)
Structure-deformation pattern analysis was made on a highly textured 8090 AI-Li alloy sheet deformed in tension. It is shown that the sharp beta-fiber type crystallographic texture induces a strong orientation variation ...
New inorganic-organic hybrid: Synthesis and structural characterization of an alumino(oxalato)phosphate
(Amer Chemical Soc, Washington, 2003)
A new 3-D alumino(oxalato)phosphate, [H3NCH(CH3)CH2NH3](2)[Al4P6O20(OH)(4)(C2O4)(H2O)], consists of aluminophosphate layers which are pillared by oxalate anions. It contains a hybrid 12-membered channel where guest species, ...
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 ...
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 ...
Study of quantitative structure-retention relationships for s-triazine derivatives in different RP HPTLC systems
(Akadémiai KiadóSpringer, 2005)
Quantitative structure-retention relationships (QSRR) have been used to study the chromatographic behavior of some s-triazines. Retention factors, RM0, on C18 layers corresponding to zero percent organic modifier in the ...
Microstructure and mechanical properties of Al-4·4 wt-%Mg alloy (AA5182) after equal channel angular pressing
(Maney Publishing, 2005)
Equal channel angular pressing (ECAP) has been used to process an Al-4-4 wt-%Mg alloy (AA5182) at room temperature (RT), 200°C and 400°C. The evolution of microstructure and mechanical properties after ECAP has been studied ...
UV-curable hyperbranched urethane acrylate oligomers containing soybean fatty acids
(Elsevier Science Sa, Lausanne, 2005)
Urethane acrylate resins based on partially modified aliphatic hyperbranched polyesters (HBP) have been synthesized. HBP of the second and the third generation were synthesized from 2,2-bis(hydroxymethyl)propionic acid and ...
Influence of the electrode parameters on pulse shape characteristic of gas-filled surge arresters at small pressure and inter-electrode gap values
(IEEE-Inst Electrical Electronics Engineers Inc, Piscataway, 2005)
The aim of this paper is to present the influence of electrode system parameters on electrical breakdown of gas (electrode effect) with the purpose to improve the gas-filled surge arresters (GFSAs) protective characteristics ...
Influence of the electrode parameters on the pulse shape characteristic at small pressure and inter-electrode gap values
(IEEE Conference Record - Abstracts: The 31st IEEE International Conference on Plasma Science, ICOPS2004, 2004)
Gas filled surge arresters (GFSA) has working point close to minimum on Paschen curve. Below that point breakdown follows Townsend's mechanism, i.e. the secondary processes on the electrodes dominate the secondary processes ...
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 ...
