Self-Nucleation Effects on Polymer Crystallization

Macromolecules, 2020
The existence of a “memory” of the previous crystalline state, which survives melting and enhances recrystallization kinetics by a self-nucleation process, is well-known in polymer crystallization ...

Self-interaction chromatography as a tool for optimizing conditions for membrane protein crystallization [PDF]

, 2010
The second virial coefficient, or B value, is a measurement of how well a protein interacts with itself in solution. These interactions can lead to protein crystallization or precipitation, depending on their strength, with a narrow range of B values ...

Unveiling the self-association and desolvation in crystal nucleation

IUCrJ, 2021
As the first step in the crystallization process, nucleation has been studied by many researchers. In this work, phenacetin (PHEN) was selected as a model compound to investigate the relationship between the solvent and nucleation kinetics.

A Study on crystallization temperature and rate of ammonium salt in the high-pressure hydrogenation heat exchanger [PDF]

E3S Web of Conferences, 2023
Ammonium salt crystallization corrosion failure is an essential problem in the failure of high-pressure hydrogenation heat exchangers. The crystallization equilibrium curves of NH4Cl and NH4HS under different pressures were established according to the ...

Explosive crystallization mechanism of ultradisperse amorphous films [PDF]

, 1999
The explosive crystallization of germanium ultradisperse amorphous films is studied experimentally. We show that crystallization may be initiated by local heating at the small film thickness but it realizes spontaneously at the large ones.

Magnetic bubble crystal in tetragonal magnets [PDF]

Phys. Rev. B 108, 024426 (2023), 2023
A magnetic bubble crystal is a two-dimensional soliton lattice consisting of multiple spin density waves similar to a magnetic skyrmion crystal. Nevertheless, the emergence of the bubble crystal with a collinear spin texture is rare compared to that of the skyrmion crystal with a noncoplanar spin texture.
