poly(ethylene adipte) and poly(ethylene adipate)/silica nanocomposite (pead/sio2) containing 3 wt. % sio2  were prepared by an in situ method. the examinations on the non-isothermal crystallization kinetic behavior have been conducted by means of differential scanning calorimeter (dsc). the avrami, ozawa, and combined avrami and ozawa equations were applied to describe the crystallization kinet...

We derive a model for the non-isothermal reaction-diffusion equation. Combining ideas from non-equilibrium thermodynamics with energetic variational approach we obtain general system modeling evolution of chemical reaction mass kinetics. From this recover linearized close to equilibrium and analyze global-in-time well-posedness small initial data critical Besov space.

This research is aimed to undertake a comparative study on stability and thermal degradation kinetics of un-irradiated and high energy protons irradiated polyvinyl butyral (PVB) based on weight loss analysis and non-isothermal approaches. The weight loss by the un-irradiated PVB upon heating was found to be in two stages but due to high energy protons accelerated exposure following by chemical ...

Torrefaction of biomass is a promising pre-treatment process capable substantially improving the properties raw for its use as solid biofuel, among many other potential applications. Oxygen-lean torrefaction can effectively reduce cost and complexity inert torrefaction. In this work, tests crushed olive stones were conducted in thermogravimetric analyzer various oxygen concentrations, under bot...

Cumene Hydroperoxide (CHP) has been used in the production of Dicumyl Hydroperoxide (DCPO) and phenol. In Taiwan, several severe fire or explosion incidents have occurred due to its thermal instability or reactivity. In this research, the exothermic decomposition of CHP in Cumene was characterized by isothermal microcalorimeter, TAM (thermal activity monitor), because isothermal testing offers ...

Dehydration of ethanol via adsorption on 3Å molecular sieves has recently been increasing in application in industry as an alternative to the conventional separation techniques for breaking the ethanol-water azeotrope. Over the past 20 years, Pressure-Vacuum Swing Adsorption (PSA) processes have gained increasing commercial acceptance as an energy-efficient separation technique. A general purpo...

A micro-kinetic model C1 C2 hydrocarbon oxidation the Pt(1 1 1) surface established using density functional theory tuned validated based experimental results obtained from Density (DFT) modelling carried out to evaluate coverage selected species thermochemistry kinetics. reasonably...

The crystallization of undercooled Pd43Ni10Cu27P20 melts is studied under isothermal conditions and at constant heating and cooling rates. Investigations are carried out by fluxing the melt with B2O3 and without any fluxing material. The isothermal experiments allow us to determine the complete time–temperature-transformation diagram with a minimum crystallization time of about 200 s for the fl...

The crystallization kinetics of an Al89La6Ni5 amorphous alloy were studied by thermal analysis. Both continuous heating and isothermal DSC traces showed that the Al89La6Ni5 amorphous alloy undergoes a two-stage crystallization process upon heating. The ®rst transformation, in which fcc-Al precipitates from the amorphous matrix, is a nucleation and three-dimensional di€usion-controlled growth pr...
