In the present research, the primary crystallization kinetics of the amorphous Fe85.3B11P3Cu0.7 alloy was analyzed using non-isothermal DSC measurements. The average and local activation energies, Ea, were determined by different isokinetic and isoconversional methods. The results obtained for activation energy in this research, show that due to the complexity of the primary crystallization pro...

In order to accelerate the crystallization of poly(L-lactic acid) (PLLA) biopolymer and enhance its crystallizability, biocompatible and environmentally friendly tungsten disulphide inorganic nanotubes (INT-WS2) were introduced into the polymer matrix. The non-isothermal cold-crystallization and subsequent melting behaviour of pure PLLA and PLLA/INT-WS2 nanocomposites were investigated in detai...

In this study, thermogravimetric measurements of nylon-6/polyethylene double-layer pouch wastes were conducted in N2 under a constant heating-rate mode, and the multiple results analyzed terms degradation features specific temperatures. Experimental show that waste pyrolysis involves one reaction stage, all parameters appear to increase with heating rate. Kinetic analysis non-isothermal data wa...

Peat has attracted considerable interest as a potential source of alternative fuel in terms improving hydrocarbons production and satisfying market demand. The next decade is likely to witness raise its exploitation. Nevertheless, the characteristics peat pyrolysis process, via which many experts expect generation hydrocarbons, have not been dealt with depth. In present study we applied thermal...

An enhanced general analytical equation has been developed in order to evaluate the kinetic parameters of the thermal degradation of nanocomposites, composed of poly(lactic acid) (PLA) and organo-modified montmorillonite (OMMT) nanoparticles. This improvement has consisted of replacing the n-order conversion function by a modified form of the Sestak-Berggren equation that led to a better adjust...

Providing a minimum of theory, this review focuses on practical aspects analyzing the kinetics nonisothermal crystallization as measured with differential scanning calorimetry (DSC). It is noted that kinetic analysis dominated by approaches based Avrami and Arrhenius equations. Crystallization should not be considered synonymous model, whose applications are subject to very restrictive assumpti...
