having sufficient and accurate understanding about kinetics of phenomena, could be an important reason for further technological progresses. finding a white-box mathematical model for weight vs. time curves of electrophoretic deposition (epd) using large and small signal analysis has been studied thoroughly in the present investigation. weight-time curves of nano-mullite suspension have been tr...

In this paper, kinetics of DC electrophoretic deposition EPD of carbon nanotubes CNTs is investigated. Carbon nanotubes suspended in pure ethanol with addition of magnesium nitrate was used as deposition media. The effect of main EPD parameters such as deposition time, applied voltage and the CNT concentration on deposit yield was investigated. The variation of current density vs. time and the ...

The total oxidation of toluene at a wide temperature range (200–500 oC) over micro/mesoporous platinated catalysts has been investigated about activity, selectivity to CO2 and CO, catalyst's stability versus coke deposition and reaction kinetics. Kinetic of toluene oxidation was measured under various oxygen and toluene pressures and als...

Nickel is an essential engineering material and electrodeposited Ni has been widely used in many fields to improve surface finishing, corrosion resistance and wear properties. The kinetics of electrochemical deposition of nickel from chloride baths in the presence and absence of saccharin on the copper substrate was investigated by applying cyclic voltammetry and chronoamperometry measureme...

In-depth understanding of the kinetics of the vapor deposition process is substantial for advancing this capable bottom-up nanostructure synthesis approach into a versatile large-scale nanomanufacturing technology. In this paper, we report a systematic study of the vapor deposition kinetics of ZnO nanomaterials under controlled atmosphere and properly refined deposition conditions. The experime...

The study of chemical reaction rates or “chemical kinetics” is fundamental to the study of chemistry itself and is intimately connected as well to life’s biochemical and biological processes. Most chemical reactions proceed by a complex mechanism that involves a series of elementary steps and it is often the role of chemical kinetics studies to identify these steps, with one typically expected ...

The influence of bacterial surface lipopolysaccharides (LPS) on cell transport and adhesion has been examined by use of three mutants of Escherichia coli K12 with well-characterized LPS of different lengths and molecular composition. Two experimental techniques, a packed-bed column and a radial stagnation point flow system, were employed to investigate bacterial adhesion kinetics onto quartz su...

The growth kinetics of polymer thin films prepared by plasma-based deposition method were explored using atomic force microscopy. The growth behavior of the first layer of the polythiophene somewhat differs from that of the other layers because the first layer is directly deposited on the substrate, whereas the other layers are deposited on the polymer itself. After the deposition of the first ...
