Nanoscale systems exhibit a rich variety of structures, quantum effects and phase transitions as a result of two primary effects: the increased importance of surface phenomena and the influence of fluctuations. We plan to develop computer simulation techniques and thermodynamic models that explicitly account for these features, then apply them to the study of phase transformations in nanosystems such as the freezing and melting of nanoparticles, the deliquescence of small atmospheric aerosols and capillarity condensation and cavitation in nanopores.

纳米系统表现出丰富多样的结构、量子效应和相变，这是两个主要效应的结果：表面现象的重要性增加和波动的影响。我们计划开发计算机模拟技术和热力学模型来明确地解释这些特征，然后将它们应用于纳米系统中的相变研究，例如纳米颗粒的冻结和融化、小大气气溶胶的潮解以及纳米孔中的毛细凝结和空化。
