The Effect of the Shear Flow on Columnar Crystal Growth in an Undercooled Melt

Metals, 2022
Herein, the effect of the shear flow on the growth of columnar crystals in an undercooled melt is studied. The asymptotic method is used to solve the dynamic model for the growth of a columnar crystal.

Crystal growth from solutions [PDF]

Proceedings of the Royal Society of London. Series A - Mathematical and Physical Sciences, 1938
Abstract The purpose of the present paper is to provide an experimental contribution towards the knowledge of the mechanism of crystal growth from solutions. Certain details about the mechanism of crystal growth have been studied in the case of one-component systems, i. e. crystals growing from the melt or from the vapour. Very little

Growth of LiNb1−xTaxO3 solid solution crystals

Materials Chemistry and Physics, 2012
Abstract The growth of single crystals of solid solutions of LiNbO3 and LiTaO3 has been studied by using a number of different techniques: Czochralski pulling, Top-Seeded Solution Growth, flux growth from LiBO2 and LiVO3, and by optical floating zone. Crystals with homogenous Li, Ta and Nb compositions were obtained by several techniques. Analysis of

Growth of Large Hematin Crystals in Biomimetic Solutions

Crystal Growth & Design, 2014
Hematin crystallization is an essential component of the physiology of malaria parasites. Several antimalarial drugs are believed to inhibit crystallization and expose the parasites to toxic soluble hematin. Hence, understanding the mechanisms of hematin crystal growth and inhibition is crucial for the design of new drugs.

Degradation mechanism of the von Willebrand factor A2 domain by nattokinase

FEBS Letters, EarlyView.
Nattokinase, a natto‐derived protease, exhibits potent antithrombotic effects. This study demonstrates that nattokinase directly cleaves the von Willebrand factor (vWF) A2 domain in vitro. Unlike the native regulator ADAMTS13, nattokinase degrades folded vWF independently of shear stress.

Insight to the Growth Characteristics and Crystal Morphology of α‐Hemihydrate Gypsum in Na2SO4 Solution

International Journal of Ceramic Engineering & Science
The growth mechanism of α‐hemihydrate gypsum (α‐HH) in Na2SO4 solution is still undefined. In this work, we constructed the solution‐crystal models to investigate the growth morphology of α‐HH in Na2SO4 solution system by molecular dynamics simulation ...
