Crystallinity of Polymers and the Means to Influence the Crystallization Process

open access: yesCHIMIA, 1978
One of the most important factors determining the properties of a solid polymer is the packing order. Crystallization is a means to control the degree and morphology of packing.

Stress-Induced Nanoparticle Crystallization

open access: yesJournal of the American Chemical Society, 2014
Abstract We demonstrate for the first time a new mechanical annealing method that can significantly improve the structural quality of self-assembled nanoparticle arrays by eliminating defects at room temperature. Using in situ high-pressure small-angle X-ray scattering, we show that deformation of nanoparticle assembly in the presence

Crystallization-Induced Asymmetric Transformation vs Quasi-Racemate Formation in Tetravalent Boron Complexes

open access: yes, 2016
Crystallization-induced asymmetric transformation (AT) has been achieved with the salicaldimine complexes 8/9, 11/12, and 14a/15a and with the oxazaborolidinone complexes 22b/23b and 22c/23c.

Crystallization-Induced Diastereoisomer Transformation of Dihydroartemisinic Aldehyde with the Betti Base

open access: yes, 2020
Artemisinin is an important drug to fight malaria. It is produced either by extraction or via a semisynthetic route involving enzyme engineering. A key intermediate to produce artemisinin by the enzymatic route is dihydroartemisinic aldehyde (DHAAl ...

Effect of Cyanuric Acid as an Efficient Nucleating Agent on the Crystallization of Novel Biodegradable Branched Poly(Ethylene Succinate)

open access: yesMacromol, 2021
Novel biodegradable branched poly(ethylene succinate) (b-PES) composites, i.e., nucleated b-PES samples, were prepared by incorporating low loadings of cyanuric acid (CA) through a solution and casting method to enhance the crystallization rate.

A novel vesicular assay to study factors affecting cholesterol crystallization in vitro

open access: yesJournal of Lipid Research, 1996
We present an assay to study cholesterol crystallization that is fast, facile, and highly reproducible. Cholesterol crystallization from metastable vesicles was induced upon addition of bile salts and depended on the hydrophobicity of the bile salt used ...

Crystallization of polycaprolactone with low coverage of cyclodextrin

open access: yesNuclear Analysis, 2022
Crystallization kinetics of polycaprolactone (PCL) with low content of α-cyclodextrin (CD) was investigated. It was found that disordered CD can promote nucleation of PCL significantly after electrospinning, which is possibly related to CD induced slower
