Decomposition kinetics, which applied to the two observed autoacceleratory regions, was best fitted to an Avrami-Erofeyev equation with an exponent of two. The activation energy determined for the first autoacceleratory region was found to be higher than that determined for the second auto...
A study was done of the thermal decomposition of urea under open reaction vessel conditions by thermogravimetric analysis (TGA), high performance liquid chromatography (HPLC), Fourier transform-infrared (FT-IR), and an ammonium ion-selective electrode (ISE). Both evolved gases and urea residue were...
The Arrhenius relation will not be observed above the temperature at which the decomposition or, as may occur for enzymes, inactivation of one or more of the reactants occurs (Tmax). Indeed, adherence to this relation at temperatures well above Tmax for most microorganisms has been used as ev...
The thermal decomposition of propene (C3H6) was studied in a shock tube behind reflected shock waves in the temperature range 1340–1910 K at pressures aro... I Weber,L Golka,M Olzmann - 《Proceedings of the Combustion Institute》 被引量: 0发表: 2016年 Reactions of Coordinated Ligands Exem...
This study focused on the kinetic modeling of the thermal decomposition of sodium percarbonate (SPC, sodium carbonate-hydrogen peroxide (2/3)). The reaction is characterized by apparently different kinetic profiles of mass-loss and exothermic behavior as recorded by thermogravimetry and differential scan...
Moreover, during the hydrothermal/solvothermal process, the mixture of precursors decomposed and gases are removed during the decomposition process when they reach their boiling point temperature. The rapid outflow of gases from the surface urged the formation of the porous structure with various morpho...
PROBLEM TO BE SOLVED: To make reduction of film surface easy to improve the conductivity of the film by performing the heat treatment of a transparent conductive film, formed on a transparent substrate by thermal decomposing reaction in an oxidizing atmosphere and then heat-treating it in a non...
small substituents and the main polymer chains40. Generally, due to its lower thermal stability compared to cellulose and lignin41, hemicellulose decomposition prevails at lower temperatures, such as in torrefaction. Therefore, a higher hemicellulose content results in more intense devolatilization and, ...
When the particles absorb light, they create a local temperature increase, which causes the decomposition of the SPS and initiates the polymerization reaction. A broad range of wavelength absorbance, from the mid-visible (~550 nm) along almost the entire NIR range, can be achieved by ...
Incidentally, the effect of the concentration of a chemical of the TD type on the rate of the exothermic decomposition reaction, in the early stages of the self-heating process, of the chemical is assumed to be of the zeroth order in the thermal explosion theory [1]. In other words, it...
