The project is a study of concentration-dependent diffusion in supersaturated solutions of non-electrolytes. Diffusion in supersaturated solutions, particularly near critical points (e.g., consolute point) on the spinodal curve, represents a relatively unexplored phenomena at the extreme of concentration and non-ideality. Results from this project develop further understanding of the mechanisms of diffusion, as well as help predict diffusion coefficients in the supersaturated region where these transport coefficients rapidly decrease in magnitude. Diffusion data in the supersaturated range are necessary for the rational design of crystallization processes.

该项目是对非电解质过饱和溶液中浓度依赖性扩散的研究。超饱和溶液的扩散，尤其是旋转曲线上的临界点附近（例如固结点），代表了在浓度和非理想性的极端情况下相对未开发的现象。该项目的结果进一步了解了扩散机制，并有助于预测过饱和区域的扩散系数，在这些区域中，这些传输系数迅速下降。超饱和范围内的扩散数据对于结晶过程的合理设计是必需的。
