The relative crystallinity versus time plot depicts three distinct stages of crystallization process
starting from induction period, which could be observed at the initial portion of the plot.
This result further indicates that high cooling rate would hinder the forming of more crystal of PLLA during non-isothermal crystallization process
The result of a precipitation experiment is an image that is automatically generated and analyzed to determine the outcome of the crystallization process
(Jurisica et al.
0 builds on gCRYSTAL's powerful existing capabilities for batch, semi-batch and continuous crystallization process
design and operational analysis, which include capabilities for estimating growth and other kinetic parameters from experimental data, multizonal modelling - utilising links with computational fluid dynamics (CFD) software - for reliable scale-up, and industry-leading optimisation facilities.
t]([infinity]) represent the absolute crystallinity at time t and at the termination of the crystallization process
, respectively .
The reason is that there exists crystallization process
at cooling rate of5/min, but the melting crystallization almost do notoccure at higher cooling rate, which also confirms the important effect of cooling rate on the crystallization of PLLA.
Industrial crystallization process
monitoring and control.
For example, by heating the material before it can crystallize, researchers can examine the crystallization process
itself on millisecond time scales.
In everyday life, though, there is usually some crystalline impurity in contact with the liquid that will trigger the crystallization process
, and therefore the freezing.
Crystallization rate was estimated by the reciprocal of time to the local maximum of the temperature curve--the time moment when the exothermal effect of the crystallization process
was the most intensive (Fig.
They also develop SLEEK (Solid-Liquid Equilibrium Engineering Kit), a state-of-the-art software solution for crystallization process
Myerson suspects that the electric field generated by the light influences how the glycine molecules arrange themselves as they aggregate into small clusters early in the crystallization process
