acceleration and convection on materials processing. Second, there are commercial opportunities for production of unique and improved materials that cannot be prepared under normal earth conditions or in space. Through a combination of experiments and theory, we are gaining an understanding of centr

Gel Polymerization at High Gravity,ransport phenomena directly influence the resulting gel macrostructure. However, the processes forming macro- and microstructures are interconnected. Thus reciprocal influences exist, since the molecular characteristics determine such macroscopic gel parameters as elasticity, permeability, etc.

The Role of Thermal Stress In Vertical Bridgman Growth of CdZnTe Crystals, grown ingot. The computational models are shown to provide a good tool for the study of the influence of process parameters on the quality of crystals grown by this method, at least as far as thermal stress influences the defect distribution. The influence of low-g and high-g environments on growth is discussed.

Thermal Stability and the Suppression of Convection in a Rotating Fluid on Earth,rth through numerical simulations. It is shown that at least one thermal field exists for a rotating fluid with a gravitational background field where convection does not occur. The numerical model used is three-dimensional.

Convective Flows during Crystal Growth in a Centrifuge,he convective velocity depends on parameters of the centrifuge and the furnace, as well as on the properties of the melt. A simple analytical expression for the convective velocity is obtained that includes the effect of both driving factors, the radial temperature gradient and the non-uniformity of the acceleration.

Response of Temperature Oscillations in a Tin Melt to Centrifugal Effects, the convection, decreasing the temperature gradient in the melt. The latter shows different influences on the flow stability depending on the rotation sense of the centrifuge. Temperature fluctuations in the melt are considerably retarded, provided the centrifuge rotation is in the same sense as the convection roll in the melt.

Variation of Effective Impurity Segregation Coefficient in Tellurium Grown under High Gravity, charge carrier profile depended on the relationship between the impurity con-centration and the number of electrically active defects. It was shown that with steady convection, the gravity level affects the dynamics of intrinsic defect formation. The Hole mobility in ingots solidified at high gravity was lower than in the ingot solidified at 1 g.
