Crystallization of Soft Crystals

Langmuir, 2008
The crystallization of micelles formed by surfactant F127 solvated by 20% in water was investigated in the vicinity of a hydrophilic interface. Upon entering the crystalline phase from low temperature, a large correlation length develops without preferential texture.

Crystallization of Pharmaceutical Crystals

2015
The aim of this chapter is to provide students as well as industrial and academic research scientists who intend to tackle crystallization of pharmaceutical crystals with theory and practical examples. Crystallization involves two separate processes, nucleation and growth, which are rarely completely unconnected.

Models of secondary nucleation attributable to crystal‐crystallizer and crystal‐crystal collisions

AIChE Journal, 1974
AbstractThe rate of secondary nucleation of ice, assumed to be proportional to the product of collision frequency and impact energy, has been quantitatively modeled using idealized representations of collisions between crystals and either other crystals or surfaces in the crystallizer.

Crystallized vortex crystals

The European Physical Journal D - Atomic, Molecular and Optical Physics, 1998
Numerical simulations of the equations of motion of 300 charged particles confined to a plane with an additional magnetic field orthogonal to the plane reproduce recently observed self-organization of non-neutral plasmas into a small number of interacting vortices. In the presence of damping we observe crystallized vortices, i.e.

Crystal-to-Crystal Photodimerizattons

Molecular Crystals and Liquid Crystals Science and Technology. Section A. Molecular Crystals and Liquid Crystals, 1994
Abstract Most [2+2 photodimerizations proceed heterogeneously, i.e. at a certain conversion phase separation occurs which leads to the destruction of the parent crystal. The crystal fragmentation can be avoided by irradiation in the long wavelength tail of the absorption.

Motion of Crystal/Crystal and Crystal/Amorphous Interfaces

MRS Proceedings, 1990
AbstractMotion of ordered twin/matrix interfaces in films of silicon on sapphire occurs during high temperature annealing. This process is shown to be thermally activated and is analogous to grain boundary motion. Motion of amorphous/crystalline interfaces occurs during recrystallization of CoSi2 and NiSi2 from the amorphous phase. In-situ transmission

Effect of crystal attrition on crystal size distribution in continuous crystallizers

Kristall und Technik, 1973
AbstractIn a literature review is stated that the attempts to lessen the divergence between theory and practice of the determination of particle size distribution have not yet been successful. One of the significant causes of the observed deviations are abrasion and breakage.

Laser‐Induced Crystallization and Crystal Growth

Chemistry – An Asian Journal, 2011
AbstractRecent streams of laser studies on crystallization and crystal growth are summarized and reviewed. Femtosecond multiphoton excitation of solutions leads to their ablation at the focal point, inducing local bubble formation, shockwave propagation, and convection flow.
