Mathematical modeling of heavy metal ions (Cd2+, Zn2+ and Pb2+) biosorption by chemically modified short hemp fibers
(Elsevier Science Sa, Lausanne, 2011)
Biosorption, an innovative and low-cost effective method for removal of heavy metal ions from wastewaters, primarily depends on the diffusion of metal ions through the porous structure of sorbent and the resistance effects ...
Modification of glassy carbon properties under low energy proton irradiation
(Oxford : Pergamon-Elsevier Science Ltd, 2011)
Glassy carbon plates were irradiated with 15 key H(+) ion-beam in the fluence range of 1 x 10(16)-3 x 10(18) ion cm(-2). The influence of ion irradiation on surface morphology and topology was examined by scanning electron ...
Monomer elution from nanohybrid and ormocer-based composites cured with different light sources
(Elsevier Sci Ltd, Oxford, 2011)
Objectives. To study monomer elution from four resin-based composites (RBCs) cured with different light sources. Methods. Twenty-eight premolars were randomly allocated to four groups. Standardized cavities were prepared ...
Sorption of zinc by novel pH-sensitive hydrogels based on chitosan, itaconic acid and methacrylic acid
(Elsevier, Amsterdam, 2011)
Novel pH-sensitive hydrogels based on chitosan, itaconic acid and methacrylic acid were applied as adsorbents for the removal of Zn2+ ions from aqueous solution. In batch tests, the influence of solution pH, contact time, ...
Decolorization of reactive textile dyes using water falling film dielectric barrier discharge
(Elsevier, Amsterdam, 2011)
Decolorization of reactive textile dyes Reactive Black 5, Reactive Blue 52, Reactive Yellow 125 and Reactive Green 15 was studied using advanced oxidation processes (AOPs) in a non-thermal plasma reactor, based on coaxial ...
Dissolution Behavior of Different Celluloses
(Amer Chemical Soc, Washington, 2011)
Celluloses from different origins were dissolved stepwise in N,N-dimethylacetamide/lithium chloride (9% v/w; DMAc/LiCl) with the aim to study the time course of the dissolution process, Completeness of dissolution in the ...
Non-noble metal composite cathodes for hydrogen evolution. Part I: The Ni–MoOx coatings electrodeposited from Watt’s type bath containing MoO3 powder particles
(Elsevier, 2011)
In this work the Ni–MoOx coatings have been prepared and characterized in view of their possible application as electrocatalysts for hydrogen evolution reaction (HER) in alkaline solution. The procedure of deposition of ...
Wear and corrosion behaviour of Ti-13Nb-13Zr and Ti-6Al-4V alloys in simulated physiological solution
(Pergamon-Elsevier Science Ltd, Oxford, 2011)
Wear and corrosion behaviour of cold-rolled Ti-13Nb-13Zr alloy, with martensitic microstructure, and Ti-6Al-4V ELI alloy, in martensitic and two-phase (alpha + beta) microstructural conditions, was studied in a Ringer's ...
The effect of T4 heat treatment on the microstructure and corrosion behaviour of Zn27Al1.5Cu0.02Mg alloy
(Pergamon-Elsevier Science Ltd, Oxford, 2011)
The effect of heat treatment on the microstructure and corrosion behaviour of Zn27Al1 5CuO 02Mg alloy was examined The alloy was prepared by melting and casting route and then thermally processed (T4 regime) Corrosion ...
