In this award, funded by the Chemical Structure, Dynamics and Mechanisms A (CSDM-A) Program of the Division of Chemistry, Professor Andrey Vilesov of the University of Southern California and his graduate student researchers are conducting experiments to study the behavior of atoms and molecules in the unique environment of liquid helium droplets. The results from these experiments are of fundamental interest to the physical chemistry and condensed matter physics communities. Graduate students working on this project will receive training in high vacuum science, cryogenics and laser science. Prof. Vilesov is active in educational innovation on his campus, and he mentors a diverse group of young scientists. Prof. Vilesov and his research group are continuing work on atomic and molecular properties of species isolated in the unique environment of helium nanodroplets. Prof. Vilesov and his group will: (1) conduct single droplet ionization experiments; (2) study heat transfer in He droplets; (3) image very large He droplets (using x-ray scattering at SLAC); (4) study the structure, properties and formation of metal clusters confined to He droplets; (5) investigate the formation of so-called foam of Mg in He droplets; (6) study the magnetic properties of species confined to He droplets; and (7) investigate the ability of He nanodroplets to gently deposit unusual species onto surfaces. The young researchers working in the group of Prof. Vilesov will receive training in experimental physical chemistry.

在这个由化学系化学结构、动力学和机制A（CSDM-A）计划资助的奖项中，南加州大学的Andrey Vilesov教授和他的研究生研究人员正在进行实验，研究原子和分子在液氦液滴独特环境中的行为。 这些实验的结果对物理化学和凝聚态物理界具有根本的意义。 从事该项目的研究生将接受高真空科学、低温学和激光科学的培训。 Vilesov教授积极参与校园教育创新，并指导了一批多元化的年轻科学家。Vilesov教授和他的研究小组正在继续研究在氦纳米液滴的独特环境中分离的物种的原子和分子特性。 Vilesov教授和他的团队将：（1）进行单液滴电离实验;（2）研究He液滴中的传热;（3）对非常大的He液滴进行成像（4）研究了氦液滴中金属团簇的结构、性质和形成过程，（5）研究了氦液滴中镁泡沫的形成过程，并对氦液滴中镁泡沫的形成机理进行了研究。（6）研究限制在He液滴中的物质的磁性;（7）研究He纳米液滴将不寻常物质缓慢存款到表面上的能力。 在Vilesov教授小组工作的年轻研究人员将接受实验物理化学的培训。
