Thermodynamic modeling of vapor-liquid equilibria and excess properties of the binary systems containing diethers and n-alkanes by cubic equation of state
(Korean Institute Chemical Engineers, Seoul, 2004)
A comparison of the performances of two different approaches of cubic equations of state models, based on a classical van der Waals and mixing rules incorporating the G(E) equation, was carried out for correlation of ...
Protective properties of epoxy coatings electrodeposited on steel electrochemically modified by Zn-Ni alloys
(Elsevier Science Sa, Lausanne, 2004)
A review is given on Zn-Ni alloys electrochemically deposited on steel under various deposition conditions. The influence of deposition current density and type of deposition solution on the chemical content, phase structure ...
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 ...
Polyacrylamide and poly(itaconic acid) complexes
(Pergamon-Elsevier Science Ltd, Oxford, 2004)
Intermolecular complex formation through hydrogen bonding between poly(itaconic acid), partially neutralized and non-neutralized, and polyacrylamide was studied by potentiometry. The complexes were obtained by template ...
Obtaining crystals in a laboratory furnace
(Elsevier, Amsterdam, 2004)
A model of an air cooler (telescopic cold bridge) with a column of Tamman test tubes (telescopic test comb), installed in a laboratory tube furnace, for regulation and simultaneous crystallization tests at different ...
The influence of low-temperature plasma treatment on some wool properties
(American Institute of Physics, 2004)
If swift heavy ions (5 MeV/u) hit solid targets energy is transferred to the electrons of the solid. Caused by the high electronic energy deposition along the flight path of the ion a cylindrical shaped chemical or structural ...
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 ...
Optimization of artificial neural network for retention modeling in high-performance liquid chromatography
(Elsevier, Amsterdam, 2004)
An artificial neural network (ANN) model for the prediction of retention times in high-performance liquid chromatography (HPLC) was developed and optimized. A three-layer feed-forward ANN has been used to model retention ...
Estimation of elastic properties of a particulate polymer composite using a face-centered cubic FE model
(Elsevier, Amsterdam, 2004)
A three-dimensional (31)) finite element (FE) unit cell model is applied to studies on the elastic properties of ceramic spherical particle-polymer composite. In this model, hydroxyapatite particles (HAp) are assumed to ...
Cell support studies aimed for cartilage tissue engineering in perfused bioreactors
(Trans Tech Publications Ltd, Durnten-Zurich, 2004)
Cartilage tissue engineering based on chondrogenic cells seeded onto biodegradable polymer supports and cultivated in bioreactors can potentially become an effective method for creating functional tissue equivalents. ...
