INFLUENCE OF MELT OVERHEATING NAPHTHALENE, DIPHENYL AND DIBENZYL ON CRYSTALLIZATION

open access: yesФизико-химические аспекты изучения кластеров, наноструктур и наноматериалов, 2014
A sharp change in naphthalene, diphenyl, and dibenzyl crystallization behavior from the equilibrium without overcooling to the nonequilibrium-explosive with overheating was determined bythermoanalysis.

Crystallization kinetics of poly(lactic acid)-talc composites [PDF]

open access: yes, 2011
The crystallization kinetics of Poly(lactic acid) / talc composites were determined over a range of 0 wt.% to 15 wt.% of talc. Talc was found to change the crystallization kinetics.

Early-stage bifurcation of crystallization in a sphere

open access: yesNature Communications, 2023
Bifurcations in kinetic pathways decide the evolution of a system. An example is crystallization, in which the thermodynamically stable polymorph may not form due to kinetic hindrance.

Effects of crystallization kinetics on the dielectric and electrical properties of BiFeO3films

open access: yesJournal of Advanced Dielectrics, 2021
BiFeO3 thin films were prepared using the chemical solution route on Pt/TiO2/SiO2/Si(100) substrates under different crystallization kinetics. The crystallization kinetic effects on the dielectric and electrical properties have been investigated.

Determination of the kinetic parameters for crystallization directly from isothermal DSC curves

open access: yesDiscover Chemistry
The determination of crystallization kinetic parameters is central to elucidating the transformation mechanisms in glassy systems, particularly when analyzed within the framework of the Kolmogorov–Johnson–Mehl–Avrami equation. In this paper, we show that

Crystallization kinetics of safflower and olive oils during low-temperature storage

open access: yesGrasas y Aceites, 2019
The crystallization behaviors of safflower and olive oils were investigated according to changes in volume and transmitted light intensity during isothermal storage at low temperature. The changes between the oils were significantly different even though

In silico and in vitro exploration of a tyrosinase for biocatalytic production of catechols

open access: yesFEBS Open Bio, EarlyView.
Tyrosinase from Ralstonia pseudosolanacearum is a promising biocatalyst for producing valuable catechols from monophenol substrates. This tyrosinase is uniquely suited to this due to its high monophenolase : diphenolase ratio. We combined in silico docking and in vivo kinetic characterisation of this tyrosinase with 11 industrially relevant monophenols,

Enhancement of Crystallization Process of the Organic Pharmaceutical Molecules through High Pressure

open access: yesCrystals, 2022
The enhancement of the crystallization process through high pressures was studied by using ribavirin (RVB) as a model compound. The effects of high pressure on crystallization thermodynamics, nucleation kinetics, and process yield were evaluated and ...
