The proposed research will leverage my internationally recognized track record in developing and applying a deep mastery of many branches of thermodynamics to provide theoretical frameworks, equations and insight needed to understand, predict, design, and control complex multicomponent, multiphase systems and processes. Multicomponent, multiphase systems (drops, bubbles, emulsions, foams, aerosols, and multiphase fluids in solid porous media) and processes (wetting, melting/solidification, evaporation/condensation) that will be addressed by this research occur in almost every manufacturing, natural resources, and energy industry; are the basis for novel surface, microfluidic and nano-technologies; are central to complex processes in the environment; and are the focus of much of modern science. While 135-year old Gibbsian surface thermodynamics is the underlying science describing multicomponent high-surface-area fluids, the most thermodynamically correct work has been done only for relatively uncomplicated systems. The proposed research will address many currently outstanding problems under three broad objectives: 1) Provide equilibrium thermodynamics for a wide range of industrially, scientifically and environmentally important multiphase systems dominated by curvature and other interfacial phenomena. 2) Develop nonequilibrium thermodynamics approaches to describe mass transfer at interfaces in nonideal, multicomponent systems and solve the coupled equations of interfacial transport, adjoining-bulk-phase transport, and heat transport for various geometries and experimental circumstances. 3) Compare theoretical predictions with fundamental experiments, done both in our group and in other leading experimental laboratories, for validation and theory refinement. The long-term impact of this work will be to advance modern thermodynamics to the point of incorporation of curved surface phenomena and evaporation/condensation rates into the toolbox of future engineers and into commercial thermodynamic simulators. I strive for high quality research, applying rigorous thermodynamics and creative approaches to solve important challenging problems, providing fundamental insight that applies across applications and opens up new fields of research. My research has been recognized by six national awards, invitations to serve on international editorial boards, and invitations to speak at top conferences and universities. An important mission of my Discovery Grant program is to train the world's top thermodynamicists. I attract outstanding Canadian and international graduate students and postdoctoral fellows (HQP) and give them the comprehensive training and high-quality supervision that they deserve, enabling them to reach their full potential. My HQP have had outstanding success in academia, government and industry.**

拟议的研究将利用我国际认可的往绩来开发和应用许多热力学分支，以提供理论框架，方程和洞察力，以了解，预测，设计和控制复杂的多组分，多相系统和过程所需的理论框架，方程式和洞察力。多种组分，多相系统（滴，气泡，乳液，泡沫，气溶胶和多型多孔介质中的多相流体）和该研究将在几乎所有的制造，自然资源和能源行业以及能源行业中都发生在几乎所有研究中，这些研究都将在此研究中得到解决；是新型表面，微流体和纳米技术的基础；是环境中复杂过程的核心；是现代科学的大部分重点。虽然135岁的Gibbsian表面热力学是描述多组分高表面环境流体的基础科学，但最热力学上最正确的工作仅是针对相对简单的系统进行的。拟议的研究将解决以下三个广泛目标下的许多目前出现的问题：1）为各种以曲率和其他界面现象为主的工业，科学和环境重要的多相系统提供平衡热力学。 2）开发非平衡热力学方法来描述非理想的多组分系统中的界面的传质，并求解界面传输的耦合方程，相邻的占相相传输以及各种几何和实验环境的热传输。 3）将理论预测与基本实验进行比较，在我们的小组和其他领先的实验实验室中进行了验证和理论的改进。这项工作的长期影响将是将现代热力学提高到将弯曲的表面现象和蒸发/冷凝速率纳入未来工程师的工具箱，并将其纳入商业热力学模拟器。我努力进行高质量的研究，采用严格的热力学和创造性方法来解决重要的具有挑战性的问题，提供适用于应用程序的基本见解，并开辟了新的研究领域。我的研究得到了六项国家奖项，在国际社论委员会任职的邀请以及在顶级会议和大学发表讲话的邀请。我的发现赠款计划的一个重要任务是培训世界顶级的热力学家。我吸引了杰出的加拿大和国际研究生以及博士后研究员（HQP），并给予他们应有的全面培训和高质量的监督，使他们能够发挥全部潜力。我的HQP在学术界，政府和工业中取得了巨大的成功。**
