A detailed reaction mechanism for the oxidation of aluminum with CO2 in gas phase has been investigated. Quantum chemical calculations were performed to obtain molecular structures intermediates and transition states on pathways. highly accurate method was applied calculate potential energies thermodynamic properties structures. The rate coefficients each path also obtained from theory. kinetic...

We describe a detailed depth-and time-dependent model of the molecular cloud associated with the ultracompact H ii region G34.3+0.15. Previous work on observations of NH 3 and CS indicates that the molecular cloud has three distinct physical components:-an ul-tracompact hot core, a compact hot core and an extended halo. We have used the physical parameters derived from these observations as inp...

The measurements of the overall bicyclic peroxy radical + NO rate constant for the 1,3,5-trimethylbenzene (1,3,5-TMB) system and of the nitrate product yields for the benzene, toluene, p-xylene, and 1,3,5-TMB systems were performed via the turbulent flow chemical ionization mass spectrometry technique. While the overall rate constant was found to be consistent with the value used in the most de...

A chemical engineering approach for the rigorous construction, solution, and optimization of detailed kinetic models for biological processes is described. This modeling capability addresses the required technical components of detailed kinetic modeling, namely, the modeling of reactant structure and composition, the building of the reaction network, the organization of model parameters, the so...

The full spectrum from attachment-kinetic-dominated to diffusion-controlled modes is revealed for the cases of monolayer h-BN chemical vapor deposition (CVD) growth and Ar/H2 etching. The sets of grown and etched structures exhibit well-defined shape evolution from Euclidian to fractal geometry. The detailed abnormal processes for merging h-BN flakes into continuous structures or film are first...

A novel method for the in situ generation of catalytically active small metal nanoparticles, by anion extrusion on a parent porous copper chloropyrophosphate framework, has been developed to generate gold, platinum and palladium nanoparticles for sustainable catalytic oxidations using molecular oxygen as the oxidant. Transmission electron microscopy coupled with detailed structural and physico-...

The kinetic of Fischer-Tropsch synthesis over a co-precipitated Fe-Ce catalyst was investigated in a fixed bed micro reactor. Experimental conditions were varied as follow: reaction pressure 1-15bar, H¬¬¬2/CO feed ratio of 1-3 and space velocity of 3600-5400 h-1 at the temperature range of 270-310°C. 4 models according to the Langmuir-Hinshelwood-Hougen-Watson (LHHW) type rate equation were der...

Abstract Detailed balance of a chemical reaction network can be defined in several different ways. Here we investigate the relationship among four types detailed conditions: deterministic, stochastic, local, and zero-order local balance. We show that are equivalent when reactions lead to species changes not some same change. Under condition balance, further system has global potential over whol...
