We use Attainable Region (AR) techniques to generate reactor network synthesis solutions to the WGS reaction system. We do this using the conventional method as described by Nicol et al. (1997) to generate the candidate AR (AR) for exothermic reversible reactions in three dimensions. We compare the results with two other automated techniques, namely: the isostate algorithm (Rooney et al. 2000) ...

An energetic micro-initiator through integrating Al/Ni nano-multilayers with Cu film bridge was investigated in this study. The Cu film bridge was initially fabricated with wet etching, and Al/Ni nano-multilayers were alternately deposited on the surface of Cu film bridge by magnetron sputtering. The periodic layer structure of Al/Ni nano-multilayers was verified by scanning electron microscopy...

A new low-temperature method to produce (InxGa1−x)2O3 (x 4 0.1, 0.2, and 0.3) powders with high purity, high chemical homogeneity and improved crystallinity in the as-synthesized state has been developed. This procedure produced finely divided powders through an exothermic reaction between the precursors. The process starts with aqueous solutions of In(NO3)3 and Ga(NO3)3 as the precursors and h...

We report the application of the "internal trigger" approach to multistep microfluidic polymerization reactions conducted in droplets, namely, polyaddition and polycondensation. We hypothesized and experimentally established that heat generated in an exothermic free radical polymerization of an acrylate monomer (Reaction 1) triggers the polycondensation of the urethane oligomer (Reaction 2). Co...

Sabatier's principle suggests, that for hydrogen evolution a plot of the rate constant versus the hydrogen adsorption energy should result in a volcano, and several such plots have been presented in the literature. A thorough examination of the data shows, that there is no volcano once the oxide-covered metals are left out. We examine the factors that govern the reaction rate in the light of ou...

Ambient hydrolysis products in moist air and hydrolysis kinetics in argon with humidity of RH1.5% for polycrystalline LiH powders and sintered bulks were investigated by X-ray diffraction, Raman spectroscopy and gravimetry. The results showed that the hydrolysis products made up a layered structure of LiOH•H2O/LiOH/Li2O from surface of the sample to inside. In low humid argon atmosphere, the pr...

This research presents the kinetics of saponification reaction using mixed fats olein and stearin [in ratio (3:1)] with NaOH solution. In this reaction, excess solution was used to ensure being irreversible. Three parameters were varied show their effects on rate .They are: percentage (10 % - 100 %) , temperature (100-150)oC stirring speed (400-1100) rpm. It noticed that increasing enhances whi...

The solid state thermochemical decomposition kinetics and activation energy of neat 1,3,5,5-tetranitrohexahydropyrimidine (DNNC) and its DNNC-d6 deuterium labeled analogue were obtained by isothermal differential scanning calorimetry (IDSC) at 142, 145, and 148 ◦C. Global rate constants and kinetic deuterium isotope effect (KDIE) data from the exothermic decomposition process suggest that homol...

The doping reaction of truncated boron nitride and carbon nanotubes with aluminium atom wastheoretically investigated. The AM1, PM3, and PM6 semiempirical methods have been used toevaluate the thermochemistry of doping reactions of single walled boron nitride nanotubes andcarbon nanotubes. The enthalpy changes, Gibbs free energy changes, and entropy changes of studieddoping reactions were evalu...
