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 ...
Synthesis of antimicrobial monophase silver-doped hydroxyapatite nanopowders for bone tissue engineering
(Elsevier, Amsterdam, 2011)
Monophase silver-doped hydroxyapatite (AgxCa10-x(PO4)(6)(OH)(2); 0.002 lt = x lt = 0.04) nanoparticles were prepared using a neutralization method and investigated with respect to potential medical applications. This ...
Thermal and optical properties of silver-poly(methylmethacrylate) nanocomposites prepared by in-situ radical polymerization
(Pergamon-Elsevier Science Ltd, Oxford, 2010)
Surface modified silver nanoparticles dispersed in chloroform were encapsulated in poly(methylmethacrylate) (PMMA) by in-situ radical polymerization of methyl methacrylate initiated by 2,2'-azobisisobutyronitrile. The ...
Evaluation of periodic operation of a trickle-bed reactor based on empirical modeling
(Pergamon-Elsevier Science Ltd, Oxford, 2010)
In this paper, we propose a new procedure for fast evaluation of the potential of periodic operations in trickle-bed reactors, based on empirical modeling. Step response experiments, with different input amplitudes, were ...
New Hybrid Properties of TiO2 Nanoparticles Surface Modified With Catecholate Type Ligands
(Springer, New York, 2010)
Surface modification of nanocrystalline TiO2 particles (45 ) with bidentate benzene derivatives (catechol, pyrogallol, and gallic acid) was found to alter optical properties of nanoparticles. The formation of the inner-sphere ...
