Distinct Crystallization Pathways of Polyoxymethylene in Methanol System
CrystalsRecrystallization of polyoxymethylene (POM) in solvent is an effective post-treatment method for manufacturing a better POM product. Herein, the crystallization process of POM in methanol was investigated with the use of a series of equipment.

Molecular tectonics: from crystals to crystals of crystals [PDF]
Chemical Communications, 2013 The in situ combination of M(II) cations (Co, Ni, Cu or Zn) with 2,4,6-pyridinetricarboxylic acid as a ligand, a bisamidinium dication as a H-bond donor tecton and NaOH leads to the formation of anionic metal complexes ML2(2-) and their interconnection into isomorphous 3D H-bonded networks displaying different colours which were used as preformed seed ...

Crystallization and Crystal Data of Monellin [PDF]
Proceedings of the National Academy of Sciences, 1975 Crystals of monellin, a sweet protein from Dioscoreophyllum cumminsii , were grown by vapor diffusion of 20% ethanol into buffered protein solution. The crystals are orthorhombic, belonging to space group P2 1 2 1

Solubility and Crystallization of Piroxicam from Different Solvents in Evaporative and Cooling Crystallization [PDF]
, 2021 In this work, the solubility of a non-steroidal anti-inflammatory drug (NSAID), piroxicam, is investigated. The polymorphic form II, which is the most stable form at room temperature, was investigated in seven different solvents with various polarities ...

crystal-torture: A crystal tortuosity module [PDF]
Journal of Open Source Software, 2019 crystal-torture is a Python, Fortran, and OpenMP module for the analysis of diffusion networks in crystal structures. Ionic diffusion through crystalline solids depends not only on the dynamics of ions within the crystal, but also the connectivity of the transport network.Understanding how the connectivity of diffusion pathways in crystal structures is

Application of Two-Dimensional Correlation Analysis to Explosives Detection and Polymer Crystallization [PDF]
, 2010 This thesis presents two novel applications of two-dimensional (2D) correlation analysis: (1) long standoff detection of explosives and (2) morphology development in semicrystalline materials. Due to the dangers of improvised explosive devices (IEDs),

Self-interaction chromatography as a tool for optimizing conditions for membrane protein crystallization [PDF]
, 2009 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 ...

Computational crystallization [PDF]
Archives of Biochemistry and Biophysics, 2016 Crystallization is a key step in macromolecular structure determination by crystallography. While a robust theoretical treatment of the process is available, due to the complexity of the system, the experimental process is still largely one of trial and error.
