Abstract:

Abstract: Decomposition characteristics of some newly synthesized chalcones have been studied by thermo gravimetric and differential scanning calorimetric analysis. From thermo grams, some kinetics parameters of decomposition were also evaluated. It is observed that thermal stability and decomposition kinetics depends on nature and position of substituent present in these compounds.

Abstract:

Maize starch is abundant in quantity in China. The hazard from dust explosion of maize starch was very great. Number simulation is a good way to predict the consequent of dust explosion, but the known of reaction kinetics of hazardous materials is necessary. The objective of this research was to determine the reaction kinetics of maize starch using thermo-gravimetric analyses. Thermo-gravimetric analyses of maize starch were performed at heating rates of 5, 10, and 15 min-1 in an air atmospheres. The weight losses of maize starch in an air atmosphere were found to occur in three stages. The pa

Abstract:

It has been established that the kinetic curves of adhesion (strength increase) are of the sigma type with the displacement period of the second stage relative to the first one. The period of this displacement is determined by starting of a marked metal flow over the micro-protrusion contact sections and its passing on the baton into a harder material under the second kind stresses. Activation of the contact surface of a harder material (corundum) occurs due to a handover of the deformation of the surface layer is plastically deformed micro-protrusions (grains) of the metal due to the effect o

Abstract:

In this paper, detailed comparisons of the driving force in thermodynamics and intrinsic force in the kinetics of 1,2-dihydropyridine and 1,4-dihydropyridine isomers of PNAH, HEH, and PYH in hydride transfer reactions are made. For 1,2-PNAH and 1,4-PNAH, the values of the thermodynamic driving forces, kinetic intrinsic barriers, and thermo-kinetic parameters are 60.50 and 61.90 kcal/mol, 27.92 and 26.34 kcal/mol, and 44.21 and 44.12 kcal/mol, respectively. For 1,2-HEH and 1,4-HEH, the values of the thermodynamic driving forces, kinetic intrinsic barriers, and thermo-kinetic parameters are 63.4

Abstract:

AbstractCarbon dioxide is a greenhouse gas and substantially affects the global warming and climate change, so study on the adsorption of carbon dioxide is very urgent. As a new CO2 captor, Ba2Fe2O5 was prepared by the solid state reaction of Fe2O3 with BaCO3, following formula Fe2O3 + 2BaCO3 = Ba2Fe2O5 + 2CO2. The reaction kinetics in isothermal condition was investigated by using the method of thermo-gravimetric analyzer (TGA). It was found that the reaction of Fe2O3 with BaCO3 was controlled by the diffusion step in the product layer, and the kinetics process could be described by the RPP m

Abstract:

Halogen free fire-retardant silicon rubber compounds were prepared, using red phosphorus combined with magnesium hydroxide as flame retardants. The flame retardant mechanisms of red phosphorus, magnesium hydroxide were studied by means of comprehensive decomposition studies and combustion tests. The study is intended to illuminate prerequisites and the potential of red phosphorus as a fire retardant for silicone rubber in the condensed phase. The flammability was determined by limited oxygen indices （LOI） and UL 94 test. Thermo-oxidative decomposition kinetics were characterized by thermo-grav

Abstract:

The thermo-gas dynamics of fuel combustion in the combustor of aircraft engines involves thermochemical activity and combustion dynamics, but also the geometric volume of the combustion process. Research around the topic provides clues regarding the fluctuations of the combustor’s performance depending on the fuels used and the kinetics of the gas mixture determined by the internal geometry of the combustor, clues that can help initiate numerical approaches regarding the optimization of the mixture and combustion temperatures. The article proposes an approach to the combustion process in jet e

Abstract:

A systematic testing procedure has been employed to investigate the high temperature oxidation kinetics of AISI 316L. Thermo-gravimetric (TG) analysis was carried out at 950°C, 1050°C, 1150°C and 1250°C for 8h. Alongside this, isothermal furnace treatments were carried out on samples of the same material at the same temperatures for time periods of 0.5h, 1h, 2h, 4h and 8h. Changes in oxidation kinetics were observed on mass gain curves plotted from data derived from the TG analysis. When a change in oxidation kinetics was identified, the structure, thickness and composition of the oxides forme
