Phase separation in elastically coupled binary alloys
I review some of the theory[1–4] behind microstructure formation in the phase separation of binary alloys, in particular how compositional changes in a material can be affected by elastic properties of the alloy. This is done by considering a Landau-Ginzburg theory of binary alloy with an elastic interaction and solving for the elastic interactions. I also describe how finite sized confined gra...
متن کاملPhase separation in confined systems
We review the current state of knowledge of phase separation and phase equilibria in porous materials. Our emphasis is on fundamental studies of simple fluids (composed of small, neutral molecules) and well-characterized materials. While theoretical and molecular simulation studies are stressed, we also survey experimental investigations that are fundamental in nature. Following a brief survey ...
متن کاملRapid One-Step Separation and Purification of Recombinant Phenylalanine Dehydrogenase in Aqueous Two-Phase Systems
Background: Phenylalanine dehydrogenase (PheDH EC 1.4.1.20) is a NAD+-dependent enzyme that performs the reversible oxidative deamination of L-phenylalanine to phenylpyruvate. It plays an important role in detection and screening of phenylketonuria (PKU) diseases and production of chiral intermediates as well. The main goal of this study was to find a simple and rapid alternative method for pur...
متن کاملInfluence of mobile dislocations on phase separation in binary alloys
We introduce a continuum model to describe the phase separation of a binary alloy in the presence of mobile dislocations. The kinetics of the local composition and dislocation density are coupled through their elastic fields. We show both analytically and numerically that mobile dislocations modify the standard spinodal decomposition process, and lead to several regimes of growth. Depending on ...
متن کاملPhase separation of binary fluids with dynamic temperature.
Phase separation of binary fluids quenched by contact with cold external walls is considered. Navier-Stokes, convection-diffusion, and energy equations are solved by lattice Boltzmann method coupled with finite-difference schemes. At high viscosity, different morphologies are observed by varying the thermal diffusivity. In the range of thermal diffusivities with domains growing parallel to the ...
