Silver-Loaded Cotton/Polyester Fabric Modified by Dielectric Barrier Discharge Treatment
(Wiley-VCH Verlag Gmbh, Weinheim, 2009)
The preparation of antimicrobial silver-loaded cotton/polyester fabrics has been carried out by DBD surface activation followed by silver sorption from aqueous silver nitrate solution. A series of DBD fabric treatments was ...
Processing of dense nanostructured HAP ceramics by sintering and hot pressing
(Elsevier Sci Ltd, Oxford, 2009)
A nanosized HAP powder was sintered and hot pressed, in order to obtain dense HAP ceramics. In a first series of experiments, the powder was isostatically pressed into uniform green compacts and sintered at temperatures ...
Solids flow pattern in gas-flowing solids-fixed bed contactors. Part I Experimental
(Pergamon-Elsevier Science Ltd, Oxford, 2009)
An experimental investigation of the solids flow pattern in gas-flowing solids-fixed bed contactors is presented. The apparatus and procedures for determining the dynamic and static solids holdups, solids residence time ...
Solids flow pattern in gas-flowing solids-fixed bed contactors. Part II Mathematical modeling
(Pergamon-Elsevier Science Ltd, Oxford, 2009)
In this paper a mathematical model for solids flow in gas-flowing solids-fixed bed contactors is developed. The presented four-parameter model assumes plug flow with axial dispersion in the dynamic, fast moving solids zone ...
Static holdup in Gas - Flowing solids - Fixed bed contactors
(Elsevier Science Bv, Amsterdam, 2009)
Static holdup was investigated experimentally and theoretically in gas - flowing solids - fixed bed bench-scale contactors. Diverse packing elements were used: Raschig rings, ceramic beads, crushed stone and glass beads. ...
Dielectric investigation of some woven fabrics
(Amer Inst Physics, Melville, 2009)
In this paper, we have investigated the temperature dependence of dielectric properties (relative dielectric permeabilities and dielectric tangents of losses) for woven fabrics of hemp, jute, flax, cotton, polyester (PES), ...
Characterization of electrochemically synthesized PANI on graphite electrode for potential use in electrochemical power sources
(Elsevier Science Sa, Lausanne, 2009)
Polyaniline (PANI) on graphite electrode was synthesized electrochemically under galvanostatic condition at current density of 2.0 mA cm(-2) from aqueous solution of 1.0 mol dm(-3) HCl and 0.25 mol dm(-3) aniline monomer. ...
Influence of microstructure and phase composition on the nanoindentation characterization of bioceramic materials based on hydroxyapatite
(Elsevier Sci Ltd, Oxford, 2009)
The aim of the study was to investigate the influence of microstructure and phase composition on the mechanical behaviour of hydroxyapatite (HAp) and biphasic HAp/beta-tricalcium phosphate (beta-TCP) bioceramic materials ...
Electrochemical polymerization and initial corrosion properties of polyaniline-benzoate film on aluminum
(Elsevier Science Sa, Lausanne, 2009)
Electrochemical synthesis of polyaniline (PANI) on aluminum electrode from aqueous Solution Of 0.25 mol dm(-3) aniline and 0.2 mol dm(-3) sodium benzoate has been investigated under potentiodynamic and galvanostatic ...
Behavior of silicon carbide/cordierite composite material after cyclic thermal shock
(Elsevier Sci Ltd, Oxford, 2009)
In the present work Mg-exchanged zeolite and silicon carbide were used as starting materials for obtaining cordierite/SiC composite ceramics with weight ratio 30:70. Samples were exposed to the water quench test from 950 ...
