Recent advances in electron microscope fluid cell design have enabled imaging of samples in aqueous environments and have provided a platform to perform in-situ crystallization experiments as well as electrochemical studies [1-2]. However, the actual SEM imaging contrast mechanisms when imaging through the dielectric membranes of this type of fluid cell device remain unknown. In these experimen...

Crystallization during the solidification process of steels is vital importance for controlling quality final products. This paper summarizes in situ characterization research activities crystallization behaviors low-alloy process. The results obtained using high-temperature confocal laser scanning microscope (HT-CLSM) are critically reviewed, and other relevant methodologies, i.e., either clas...

This thesis presents one of the first demonstrations of continuous crystallization in microfluidic devices, and illustrates their use for various applications related to crystallization of small organic molecules. Crystallization is an important process in a number of industries, including specialty chemicals, food, cosmetics, nutraceuticals and, most importantly, pharmaceuticals. Most small mo...

The thermal properties of cis-1,4-polybutadiene (cis-PBD) were investigated in dependence of content of cis units and of linearity of the main chain. cis-PBD grades containing a fraction of cis-segments ranging from 93 to 98 %, and with linear or branched chains, were analyzed. Upon isothermal crystallization from the melt at -26 °C for 1 h, followed by cooling to below the glass transition tem...

The depletion-induced phase separation in a mixture of colloidal particles (PMMA-latex) and nonadsorbing polymers [poly(styrene)] in a solvent (mixture of tetralin, cis-decalin, and carbon tetrachloride) was investigated in real space with confocal scanning laser microscopy in the initial, intermediate, and final stage. It was found that the kinetics and the morphology of the phase separation s...

Ammonium dinitramide (ADN) is a promising oxidizing agent for solid rocket propellants. In situ XRD investigations of ADN and suspensions have been performed in order to understand refine the emulsion crystallization process manufacturing spherical particles (prills). The investigation revealed that melt behavior depends on quality, humidity, maximum temperature cycles, suspension agents. Furth...
