Microwave sintering of fine grained HAP and HAP/TCP bioceramics
(Elsevier Sci Ltd, Oxford, 2010)
The effect of microwave sintering conditions on the microstructure, phase composition and mechanical properties of materials based on hydroxyapatite (HAP) and tricalcium phosphate (TCP) was investigated. Fine grained ...
The influence of tin and silver as microstructure modifiers on the corrosion rate of Pb-Ca alloys in sulfuric acid solutions
(Wiley-VCH Verlag Gmbh, Weinheim, 2010)
The effect of microstructure modifiers, Sn and Ag, on the corrosion rate of commercial Pb-Ca alloy in H(2)SO(4) electrolyte was investigated by the potentiodynamic polarization and by the weight loss corrosion rate measurement ...
Corrosion stability of Zn-Co alloys deposited from baths with high and low Co content - The influence of deposition current density
(Elsevier Science Sa, Lausanne, 2010)
Electrochemically deposited Zn-Co alloys under various deposition conditions were investigated using atomic absorption spectroscopy (AAS) for determination of chemical composition, anodic linear sweep voltammetry (ALSV) ...
Chitosan, itaconic acid and poly(vinyl alcohol) hybrid polymer networks of high degree of swelling and good mechanical strength
(Wiley, Hoboken, 2010)
Chitosan is a biodegradable, non-toxic, biocompatible polymer convenient for use in drug delivery. In this study, hybrid polymeric networks (HPNs) based on chitosan, itaconic acid and poly(vinyl alcohol) (PVA) were prepared ...
High temporal and inter-individual variation detected in the human ileal microbiota
(Wiley, Hoboken, 2010)
P gt The diversity and temporal stability of the predominant bacteria in the human ileum was studied with the use of ileal effluent samples of seven individuals with Brooke ileostomies. The total number of bacteria within ...
Smart poly(2-hydroxyethyl methacrylate/itaconic acid) hydrogels for biomedical application
(Pergamon-Elsevier Science Ltd, Oxford, 2010)
pH- and temperature-sensitive hydrogels, based on 2-hydroxyethyl methacrylate (HEMA) and itaconic acid (IA) copolymers, were prepared by gamma-irradiation and characterized in order to examine their potential use in ...
Study on the photocatalytic degradation of insecticide methomyl in water
(Elsevier Science Bv, Amsterdam, 2010)
Photo-Fenton degradation of the insecticide methomyl in water using Fe-ZSM-5 zeolite and AlFe-pillared montmorillonite catalysts under halogen lamp light was studied. The study was performed at room temperature in a glass ...
The influence of aluminium surface pretreatment on the corrosion stability and adhesion of powder polyester coating
(Elsevier Science Sa, Lausanne, 2010)
One of the most important factors in corrosion prevention by protective coatings is the coating adhesion loss under environmental influence. Thus, adhesion strength is often used when characterizing protective properties ...
Optimization Approach for Continuous Catalytic Regenerative Reformer Processes
(Amer Chemical Soc, Washington, 2010)
The new approach for simulation and optimization of a continuous catalytic regenerative (CCR) reformer process is proposed. Typical CCR reforming processes consist of three to four reactors with recycle. The reaction ...
Fast evaluation of periodic operation of a heterogeneous reactor based on nonlinear frequency response analysis
(Pergamon-Elsevier Science Ltd, Oxford, 2010)
The concept of higher-order frequency response functions (FRFs), which is based on Volterra series representation of nonlineral systems, is used to analyse the time-average performance of a perfectly mixed reactor subject ...
