Non-Isothermal Crystallization Kinetic of Polyethylene/Carbon Nanotubes Nanocomposites Using an Isoconversional Method

open access: yesJournal of Composites Science, 2019
Behavior studies of thermoplastic polymers during non-isothermal crystallization are extremely important since most of their properties are influenced by degree of crystallinity and the crystallization process.

Kinetic pathways of crystallization at the nanoscale

Nature Materials, 2019
Nucleation and growth are universally important in systems from the atomic to the micrometre scale as they dictate structural and functional attributes of crystals. However, at the nanoscale, the pathways towards crystallization have been largely unexplored owing to the challenge of resolving the motion of individual building blocks in a liquid medium.

Kinetic Inhibitor of Hydrate Crystallization

Journal of the American Chemical Society, 2004
We present the results of a combined theoretical/experimental study into a new class of kinetic inhibitor of gas hydrate formation. The inhibitors are based on quaternary ammonium zwitterions, and were identified from a computational screen. Molecular dynamics simulations were used to characterize the effect of the inhibitor on the interface between a ...

Crystal growth kinetics of pentaerythritol

The Chemical Engineering Journal and the Biochemical Engineering Journal, 1995
Abstract The growth kinetics of pentaerythritol (PE) in aqueous solutions were determined from batch and continuous experiments; growth rate values about two orders of magnitude lower were obtained operating in batch mode. This behaviour, which agrees with previous results reported by various authors, validates the hypothesis that some impurity ...

Kinetics of Crystallization in Polydisperse Emulsions

Journal of Colloid and Interface Science, 1998
The kinetics of isothermal crystallization of the droplets in polydisperse emulsions are analyzed under the condition that each emulsion droplet gives birth to one nucleus only. Expressions are derived for the time dependences of the number of crystallized droplets and the fraction of crystallized droplet volume in the cases of either volume or surface

Crystallization kinetics of water on graphite

Physical Chemistry Chemical Physics, 2018
The nucleation and growth of water crystallites on a graphite substrate are discussed in terms of the initial film thickness, deposition temperature, and effects of adspecies.

Kinetics of Nonisothermal Polymer Crystallization

The Journal of Physical Chemistry B, 2005
We adopt a cluster size distribution model to investigate the kinetics of nonisothermal polymer crystallization. The time dependencies of polymer concentration, number and size of crystals, and crystallinity (in Avrami plots) are presented for different cooling rates.

On the kinetics of ice crystallization in batch crystallizers

AIChE Journal, 1985
AbstractThe population balance equation with respect to ice crystal size in a batch crystallizer was solved, taking into account the crystal size dependency of growth rate, and the temperature change with crystal growth was calculated. Both the temperature change and the crystal size distribution obtained theoretically were in fairly good agreement ...

Crystallization kinetics of pentaerythritol

Journal of Crystal Growth, 1996
A framework is proposed for the modelling of the crystallization kinetics of pentaerythritol in a suspension crystallizer. The main kinetic processes that are considered are those of crystal growth, attrition and secondary nucleation.

The kinetics of crystallization of hopeite

Journal of Crystal Growth, 1984
Abstract The kinetics of crystallization of α-trizinc phosphate tetrahydrate (hopeite) has been investigated over a range of supersaturation under conditions of constant solution composition. Following inoculation of supersaturated solutions with well characterized seed crystals, the activities of ion species in the supersaturated solutions were ...
