Collaborative Research: Statistical Study of the Homogeneous Nucleation by Applying a Novel Multidroplet Levitator Trap and Microscopic Theory of Homogeneous Nucleation

纽约州立大学水牛城分校研究基金会CTS-0000548E.Ruckenstein建议提高我们对均相成核现象的理解，强调提高过饱和溶液的实验纯度，并在微观水平上进行详细的理论解释。纯度(即消除经常在墙壁附近发现的污染物)将通过采用“电磁悬浮捕集器”技术实现，该技术提供并分离出性质几乎相同的大液滴样本。将可靠地测量溶质团簇和过饱和溶液之间的时空相互作用的特征：这样的宏观性质，如初始微滴的诱导时间，将能够确定最好地量化微观模型的常数。特别的兴趣集中在这个模型的随机性上。这一实验输入的准确性将取决于新设备的结构，特别是将产生成核过程的准确时间序列的“线性四极电磁悬浮陷阱”。

AbstractCTS- 0000548E.Ruckenstein, Research foundation of SUNY at BuffaloIt is proposed to advance our understanding of the phenomenon of homogeneous nucleation , with an emphasis on better experimental purity of supersaturated solutions and also with the help of a detailed theoretical interpretation at the microscopic level. Purity (i.e. the elimination of contaminants, to be found often in the neighborhood of the walls) will be achieved by employing the "electromagnetic levitation trap" technique, which provide and isolate a large sample of droplets of nearly identical properties. The characteristics of the space-time interaction between solute clusters and the supersaturated solution will be measured reliably: such macroscopic properties as the induction times of the initial microdroplets will then enable the determination of the constants which quantify best the microscopic model. Special interest is centered on the stochastic nature of this model. The accuracy of this experimental input will rest on the construction of new devices, especially the "linear quadrupole electromagnetic levitator trap" which will produce an accurate time sequence of the nucleation process.
