The aim of this paper is to analyze how different catalyst activity profiles influence the operating strategies of industrial reactors. Based on this analysis a method that can be used to transform information given by laboratory reactor experiments into a form which can be used to estimate the productivity of the catalyst and the quality properties of polymers under industrial conditions is pr...

In this paper, Reduced Graphene Oxide (rGO)/ZnFe2O4 (rZnF) nanocomposite is synthesized by a simple hydrothermal method and employed as counter electrode (CE) material for tri-iodide redox reactions in Dye sensitized solar cells (DSSC) to replace the traditional high cost platinum (Pt) CE. X-ray diffraction analysis High resolution Transmission electron microscopy, clearly indicated formation o...

Proton exchange membrane (PEM) fuel cells demonstrated to be feasible energy converters that convert chemical of fuels electrical energy. The technology has proven competitive with conventional such as batteries and internal combustion engines. However; several challenges influence the commercialization this which includes high costs, durability, stability, are contributed by PEM cell catalysts...

The presence of pharmaceutical products in the water cycle may cause harmful effects such as morphological, metabolic and sex alterations aquatic organisms selection/development resistant to antimicrobial agents. compounds’ stability persistent character hinder their elimination by conventional physico-chemical biological treatments thus, development new purification technologies has drawn grea...

Enzyme immobilization is necessary process to improve the bioactivity and stability of biocatalyst. In this study, glucose oxidase (GOx) enzyme was immobilized on plasma-treated fibrous carbon felt as a textile carrier produce heterogeneous catalyst. Genipin, naturally occurring crosslinker, that has less cytotoxicity than conventional crosslinkers, used in process. UV-Vis FTIR spectra confirme...

Two novel hydrodesulfurization (HDS) catalysts: FeN4/C and FeN2/C, were prepared using an impregnation-pyrolysis method. The two materials were investigated as catalysts for hydrodesulfurization (HDS) and hydrodearomitization (HDA) of model compounds. The turnover frequency of the two FeN catalysts is comparable to (FeN4/C) or even higher (FeN2/C) than that of MoNi/Al2O3. The FeN4/C catalyst al...

In animal behavioral biology, there are several cases in which an autonomous observing/training system would be useful. 1) Observation of certain species continuously, or for documenting specific events, which happen irregularly; 2) Longterm intensive training of animals in preparation for behavioral experiments; and 3) Training and testing of animals without human interference, to eliminate po...
