Electron diffraction studies of vapor-deposited water ice have characterized the dynamical structural changes during crystallization that affect volatile retention in cometary materials. Crystallization is found to occur by nucleation of small domains, while leaving a significant part of the amorphous material in a slightly more relaxed amorphous state that coexists metastably with cubic cryst...

In this study, we demonstrated a unique application of our Metal-Assisted and Microwave-Accelerated Evaporative Crystallization (MA-MAEC) technique for the de-crystallization of uric acid crystals, which causes gout in humans when monosodium urate crystals accumulate in the synovial fluid found in the joints of bones. Given the shortcomings of the existing treatments for gout, we investigated w...

Crystallization of calcium sulfate dihydrate (CaSO4.2H2O) in sodium chloride solutions at different supersaturation (δ = 1.2–2), pH =3, ionic strength (I = 0.5 M) and at 80°C was studied. The influence of aluminum and magnesium nitrates having very low concentrations (10 mol dm) on the rate of crystallization at different supersaturation was investigated. The rate of crystallization was found t...

Protein crystallization is a major bottleneck in protein X-ray crystallography, the workhorse of most structural proteomics projects. Because the principles that govern protein crystallization are too poorly understood to allow them to be used in a strongly predictive sense, the most common crystallization strategy entails screening a wide variety of solution conditions to identify the small su...

Many soluble proteins crystallize in conditions where their second virial coefficient takes on slightly negative values, known as the crystallization slot, allowing the possibility to screen for crystallizability by measuring virial coefficients. Here we measure virial coefficients for the membrane protein CLC-ec1, which has been crystallized. These virial coefficients reveal that CLC-ec1 cryst...

Modern X-ray structure analysis and advances in high-throughput robotics have allowed a significant increase in the number of conditions screened for a given sample volume. An efficient evaluation of the increased amount of crystallization trials in order to identify successful experiments is now urgently required. A novel approach is presented for the visualization of crystallization experimen...

The discovery of new gigantic molecules formed by self-assembly and crystal growth is challenging as it combines two contingent events; first is the formation of a new molecule, and second its crystallization. Herein, we construct a workflow that can be followed manually or by a robot to probe the envelope of both events and employ it for a new polyoxometalate cluster, Na6 [Mo120 Ce6 O366 H12 (...

The production of spherical crystals has recently gained great attention due to the fact that the crystal habit (form, surface, size, etc.) can be modified during the crystallization process. Spherical crystals of ASA were developed by non-typical and typical spherical crystallization techniques. The non-typical spherical crystallization process (conventional stirred tank method) resulted in fe...

This chapter presents an overview of industrial crystallization both from a fundamental, scientific perspective and with an eye on the application of crystallization as a separation process in industrial processes. Crystallization as a separation process yields a solid product from a solution or a melt. The process itself, the product characteristics and the temporal behavior are determined by ...

We investigated in meso crystallization of membrane proteins to develop a fast screening technology which combines features of the well established classical vapor diffusion experiment with the batch meso phase crystallization, but without premixing of protein and monoolein. It inherits the advantages of both methods, namely (i) the stabilization of membrane proteins in the meso phase, (ii) the...
