Spherical Crystallization: Modeling of the Emulsion Solvent Diffusion Technique

KONA Powder and Particle Journal, 2014
Kawashima developed the spherical crystallization technique to produce shaped and sized particles with improved properties. He presented two methods: Spherical Agglomeration (SA) and Emulsion Solvent Diffusion (ESD).

Shape Controllable Synthesis of Silver Particles by Selecting the Crystallization Routes

KONA Powder and Particle Journal, 2018
Classic crystallization describes a burst nucleation followed by a layer-by-layer atom deposition. The non-classic crystallization refers to particle mediated crystallization process.

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 ...

Effect of polystyrene on poly(ethylene terephthalate) crystallization [PDF]

Materials Research, 2014
Blends of poly(ethylene terephthalate) (PET) and polystyrene (PS) with PS content ranging from 0% to 60% by weight, were compounded in a laboratory internal mixer, followed by quenching into iced water, resulting in substantially amorphous compounds ...

Structural insights and therapeutic targets in Acinetobacter baumannii capsule biosynthesis

FEBS Letters, EarlyView.
Hypervirulent KL49 A. baumannii's capsular polysaccharide contains the nonulosonic acid 8‐epi‐Leg5,7Ac2, synthesized by epimerization via ElaA, ElaB, and ElaC. Crystal structures of ElaA, ElaB, and ElaC reveal their role in CMP‐Leg5,7Ac2 synthesis and regioselective C8 epimerization.

Water–Induced Spherical Crystallization of Pantoprazole Sodium

Separations
This study develops a spherical crystallization approach using a small amount of water, which avoids adding extra bridging agents. Notably, a new ternary solvate of pantoprazole sodium (PS–BuOH–H2O) was obtained, and its crystal structure was determined ...
