Degradation Kinetics of Polycarbonate Composites:

In order to design a reactor, kinetics of degradation of polycarbonate/CaCO3 composites was investigated here by thermogravimetric analysis (TGA), applying model-free and modelistic methods together, to obtain E, A, ΔS*, ΔH* and ΔG* (kinetic parameters).

In silico mechanically mediated atom transfer radical

In silico tracking of polymer dispersity with the help of kinetic model shows a better result compared with that by the classical dispersity equation. By defining an ultrasonic factor γ j, a qualitative analysis for the effect of ultrasound conditions on the diffusional limitation in mechanoATRP is presented.

Thermoplastic composites for ballistic application

Systematic studies of thermoplastic composites on ballistic impact failure and kinetic energy absorption mechanisms were examined on both semicrystalline and amorphous polymer matrix composites. By taking advantages of the nature of thermoplastic polymers, the main objective of this research was to develop armor grade composites with thermoplastic resin matrices through a understanding of the

Continuous or Batch Solid

This work has been intended to investigate the antioxidant properties of compounds extracted from seeds of Sterculia apetala (a plant from Central America) in order to add further results to the relatively poor existing literature on the beneficial properties of this plant. Different extraction methodologies were used such as batch or continuous extraction conditions using water or ethanol 50%

Adsorption and kinetic study of Cr(VI) on ZIF

2020/1/27Different kinetic and isotherm models were applied on equilibrium data. The adsorption process of ZIF-8 and its composites was explained by pseudo-second-order kinetic model as well as Langmuir isotherm, with maximum removal efficiency of 98% for Cr(VI) by ZIF-8/NH 2 /Mg(OH) 2 /GO.

Deep learning model to predict complex stress and strain

2021/4/5For real-world composites, their geometries can be quite complicated (45, 46). As a consequence, a relatively simple 8 8 representation may not be sufficient for practical applications. To study complex geometries, we trained an even deeper model (see Materials and Methods) with 32 32 representation ( Fig. 4C ).

Electroactive polymers for ocean kinetic energy

2018/10/2The recent issue of serious global warming has stimulated research on the development of de-carbonized energy harvesting technologies. The ocean has the most valuable natural resources which have resulted in the construction of a wide variety of offshore plants all over the world. Because nearly all offshore plants are stand-alone plants that do not transmit electricity, they must have their
