We discuss the phase behavior and in particular crystallization of a model globular protein (beta-lactoglobulin) in solution in the presence of multivalent electrolytes. It has been shown previously that negatively charged globular proteins at neutral pH in the presence of multivalent counterions undergo a ‘‘re-entrant condensation (RC)’’ phase behavior (Zhang et al., Phys. Rev. Lett., 2008, 10...

A crystal growth apparatus was designed and built to study the effect of growth modifiers, antifreeze proteins and antifreeze glycoproteins (AFGPs), on ice crystal growth kinetics and morphology. We used a capillary growth technique to obtain a single ice crystal with well-defined crystallographic orientation grown in AFGP solution. The basal plane was readily observed by rotation of the capill...

A computational model for semiconductor crystal growth on a partially masked substrate under simplified liquid phase electroepitaxy conditions is developed. The model assumes isothermal diffusional growth, which is enhanced by applied DC current through crystal-solution interface. A finite-difference, front-tracking method is used to numerically evolve the interface. Computed examples show stro...

Crystalline calcium carbonate was deposited on various substrates (substrate temperature of 80 °C) from a saturated hydrogen solution (solution 10 °C). A single aragonite phase the Al substrate, whereas mixed and calcite grew soda lime glass, borosilicate silica polycarbonate substrates. With increasing deposition time, crystal size proportion silicate glass substrate increased. Furthermore, cr...

Herein, the effect of shear flow on growth columnar crystals in an undercooled melt is studied. The asymptotic method used to solve dynamic model for a crystal. resulting solution shows that significantly changes interface morphology With forced flow, rate increases direction flow. As further increases, crystal seriously deformed and distorted. causes tend evolve into smaller initial stage grow...

Quartz is the most frequently used piezoelectric material. Single crystals are industrially grown by the hydrothermal route under super-critical conditions (150 MPa-623 K). This paper is an overview of the hydrothermal crystal growth of the AO2 and MXO4 α-quartz isotypes. All of the studies on the crystal growth of this family of materials enable some general and schematic conclusions to be mad...

We report here the growth and characterization of non linear single crystals p BaB204 (BBO) which is an interesting material for second harmonic generation. Single crystals were grown from NqO-B20, solutions using the top seeded solution growth method. The experimental set up included a Nd:YAG, Q switched, focalised with a cylindrical lens on the samples. Efficiency up to 40 % were obtained usi...
