Timescales of magma ascent in conduit models are typically assumed to be much longer than crystallization and gas exsolution for basaltic eruptions. However, it is now recognized that basaltic magmas may rise fast enough for disequilibrium processes to play a key role on the ascent dynamics. The quantification of the characteristic times for crystallization and exsolution processes are fundamen...

Here, the establishment of Europe's largest high-throughput crystallization facility with open access to the general user community is reported. The facility covers every step in the crystallization process from the preparation of crystallization cocktails for initial or customized screens to the setup of hanging-drop vapour-diffusion experiments and their automatic imaging. In its first year o...

Advances in automation have facilitated the widespread adoption of high-throughput vapour-diffusion methods for initial crystallization screening. However, for many proteins, screening thousands of crystallization conditions fails to yield crystals of sufficient quality for structural characterization. Here, the rates of crystal identification for thaumatin, catalase and myoglobin using microfl...

The crystallization and melting behaviors of linear polylactic acid (PLA) treated by compressed CO(2) was investigated. The isothermal crystallization test indicated that while PLA exhibited very low crystallization kinetics under atmospheric pressure, CO(2) exposure significantly increased PLA's crystallization rate; a high crystallinity of 16.5% was achieved after CO(2) treatment for only 1 m...

Although the activity interpretation of sucrose crystallization, already sueessfully applied to pure sucrose solutions and synthetic massesuites (11, does not require any mechanical or molecular model, it does imply (11d) an independence of any structural nature or transport behavior in the operating medium, it is therefore necessary to establish this suggested independence to warrant continued...

The crystallization properties of phase-change memory (PCM) in the presence of thermal disturbances are investigated with a novel micro-thermal stage. It is found that the recrystallization time due to thermal disturbances significantly varies depending on how the PCM cell drifts. The longer crystallization time is obtained following additional resistance drift, which can be described by an inc...

Crystallization remains a critical step in X-ray structure determination. Because it is not generally possible to rationally predict crystallization conditions, commercial screens have been developed which sample a wide range of crystallization space. While this approach has proved successful in many cases, a significant number of proteins fail to crystallize despite being soluble and monodispe...

Cocoa butter is the characteristic fat ingredient of chocolate industries, presenting itself as the most important component in all formulations. Its crystallization is a critical factor associated with the structure and properties of many confectionery foods. The stability of rich-fat processed products is influenced by changes in crystallization processes. With respect to these characteristic...

Hemozoin (Hz) is a heme crystal produced by some blood-feeding organisms, as an efficient way to detoxify heme derived from hemoglobin digestion. In the triatomine insect Rhodnius prolixus, Hz is essentially produced by midgut extracellular phospholipid membranes known as perimicrovillar membranes (PMVM). Here, we investigated the role of commercial glycerophospholipids containing serine, choli...

The deficiency in existing sugar cane crystallization automatic control system is difficult to measure some key parameters on line, such as mother liquor supersaturation, mother liquor purity, crystal content and crystal size distribution. Controlling brix with PID can only reflect the massecuite concentration of sugar cane crystallization process, but it is hard to guarantee the crystal qualit...
