Lead immobilization by geopolymers based on mechanically activated fly ash
(Elsevier Sci Ltd, Oxford, 2014)
In this paper, the effectiveness of geopolymers based on initial and mechanically activated fly ash in immobilization of lead was investigated. Fly ash (FA) was firstly mechanically and then alkali activated at room ...
Silver film on nanocrystalline TiO2 support: Photocatalytic and antimicrobial ability
(Pergamon-Elsevier Science Ltd, Oxford, 2014)
Nanocrystalline TiO2 films were prepared on glass slides by the dip coating technique using colloidal solutions consisting of 4.5 nm particles as a precursor. Photoirradiation of nanocrystalline TiO2 film modified with ...
Antimicrobial activity and biocompatibility of Ag--(+) and Cu2+ -doped biphasic hydroxyapatite/alpha-tricalcium phosphate obtained from hydrothermally synthesized Ag+- and Cu2+ -doped hydroxyapatite
(Elsevier Science Bv, Amsterdam, 2014)
Hydroxyapatite (HAp) powders doped with Ag+ or Cu2+ were synthesized by a hydrothermal method in order to obtain biomaterial with an antimicrobial effect. The synthesis was performed with two contents of dopant (Ag+ or ...
Visible light-harvesting of TiO2 nanotubes array by pulsed laser deposited CdS
(Elsevier Science Bv, Amsterdam, 2014)
Titanium dioxide (TiO2) nanotubes arrays, obtained by anodization technique and annealing, were decorated with CdS using pulsed laser deposition method. Their structural, morphological and chemical characterization was ...
Novel membrane adsorbers incorporating functionalized polyglycidyl methacrylate
(Elsevier Science Bv, Amsterdam, 2014)
Asymmetric polyethersulfone membranes with submicron particles comprising crosslinked glycidyl methacrylate copolymer were prepared by a combination of a traditional immersion precipitation process for making membranes ...
Pretreatment of Natural Materials Used for Supercritical Fluid Extraction of Commercial Phytopharmaceuticals
(Wiley-VCH Verlag Gmbh, Weinheim, 2014)
A proper method was to be developed for the pretreatment of different types of natural materials in order to increase the efficiency of supercritical fluid extraction (SFE) regarding yield and active substance content. The ...
Electrooxidative Behavior of Arylazo Pyridone Dyes and Their Inclusion Complexes on Gold Electrode in 0.1 M NaOH
(Pergamon-Elsevier Science Ltd, Oxford, 2014)
The electrochemical behavior of six arylazo pyridone dyes classified to the substituents present at the phenylazo and 2-pyridone moiety and their 1:1 inclusion complexes with (2-hydroxypropyl)-beta-cyclodextrin was studied ...
Novel Bioactive Antimicrobial Lignin Containing Coatings on Titanium Obtained by Electrophoretic Deposition
(MDPI, Basel, 2014)
Hydroxyapatite (HAP) is the most suitable biocompatible material for bone implant coatings; its brittleness, however, is a major obstacle, and the reason why research focuses on creating composites with biopolymers. ...
Immobilization of lipase on epoxy-activated Purolite((R)) A109 and its post-immobilization stabilization
(Elsevier Sci Ltd, Oxford, 2014)
In this study, Purolite (R) A109, polystyrenic macroporous resin, was used as immobilization support due to its good mechanical properties and high particle diameter (400 mu m), which enables efficient application in enzyme ...
The dependence of the photocatalytic activity of TiO2/carbon nanotubes nanocomposites on the modification of the carbon nanotubes
(Elsevier Sci Ltd, Oxford, 2014)
Nanostructural TiO2/modified multi-wall carbon nanotubes photocatalysts were prepared by hydrolysis of Ti(iso-OC3H7)(4) providing chemical bonding of anatase TiO2 nanoparticles onto oxidized- or amino-functionalized ...
