Crystallization kinetics of homopolymers: overall crystallization: a review

Biophysical Chemistry, 2004
This paper is a brief review of the overall crystallization kinetics of synthetic homopolymers. The basic experimental results are presented and compared with theory that is currently available. It is found, surprisingly, that the more sophisticated theories do no better in explaining experimental results than does the free-growth approximation.

Kinetic Theory of Crystallization

physica status solidi (a), 1982
A phenomenological approach is proposed to describe the variation with time of temperature and the amount of substance crystallized from the melt due to nucleation and nuclei growth. It is shown that depending on the heat withdrawal rate the set of relations for these values describes the main forms of transition from the liquid to the solid state ...

Kinetics of Crystallization. III

Zeitschrift für Elektrochemie, Berichte der Bunsengesellschaft für physikalische Chemie, 1957
AbstractThe rates of nucleation of crystalline cyclonite have been determined in aqueous acetone. The variations of the rate with supersaturation, solvent composition and temperature have been obtained. The results are discussed in relation to the Volmer theory.

Kinetics of triboluminescence in crystals

Journal of Physics D: Applied Physics, 1977
On the basis of the condition of instability of cracks in a stressed body it is reported that the kinetics of triboluminescence in a crystal at a strain rate r can be expressed by the relation I=I0r2t2 exp(-t/ tau )-C1, where C1 is a constant. The value of the mechanical relaxation time tau of sugar crystals has been determined from triboluminescence ...

The kinetics of sucrose crystallization

1968
This study has been undertaken for two main purposes:- (1)To obtain factual information concerning the rate of growth of sucrose crystals; and (2)To secure some understanding of the operating mechanism of factors influencing crystal growth. Chapter 3 records details of the experimental method used and data gathered for actual growth rates.

Kinetics of zeolite A crystallization

Journal of Colloid and Interface Science, 1968
Abstract Conversion of aqueous sodium aluminosilicate gels to zeolite. A was measured by means of sorption. Effects of SiO 2 Al 2 O 2 in the starting gel, caustic concentration, and stirring rate were studied. At excess silica, the gels were found to be unsuitable for kinetics studies because they tended to produce an amorphous
