The Physics of Crystallization from Globular Cluster White Dwarf Stars in NGC 6397 [PDF]

, 2009
We explore the physics of crystallization in the deep interiors of white dwarf stars using the color-magnitude diagram and luminosity function constructed from proper motion cleaned Hubble Space Telescope photometry of the globular cluster NGC 6397.

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 ...

Effect of Batchelor Flow on Polymorphic Crystallization in a Rotating Disk Crystallizer

Crystals, 2021
In this work, the influence of Batchelor flow on the polymorphic crystallization in a rotating disk (RD) crystallizer was investigated. By regulating crystallization parameters, i.e., the rotation speed, cooling rate, and ethanol fraction, we found that ...
