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在开发和应用多个热力学分支的深入掌握方面的国际公认的记录，提供理解、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、方程和见解。这项研究将涉及的多组分、多相体系(固体多孔介质中的液滴、气泡、乳液、泡沫、气溶胶和多相流体)和过程(润湿、熔融/凝固、蒸发/冷凝)几乎发生在每个制造、自然资源和能源行业；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；也是许多现代科学的焦点。尽管有着135年历史的吉布斯表面热力学是描述多组分高表面积流体的基础科学，但热力学上最正确的工作只针对相对简单的系统。这项拟议的研究将在三个大的目标下解决目前许多悬而未决的问题：1)为以曲率和其他界面现象为主导的广泛的工业、科学和环境重要的多相系统提供平衡热力学。2)发展了描述非理想多组分体系界面传质的非平衡热力学方法，求解了不同几何形状和实验条件下的界面传质、相邻体相传质和热传质的耦合方程。3)将理论预测与我们小组和其他领先实验实验室所做的基本实验进行比较，以验证和完善理论。这项工作的长期影响将是将现代热力学推进到将曲面现象和蒸发/冷凝速率纳入未来工程师的工具箱和商业热力学模拟器的程度。我致力于高质量的研究，应用严格的热力学和创造性的方法来解决重要的挑战性问题，提供适用于各种应用的基本见解，并开辟新的研究领域。我的研究得到了六个国家奖项的认可，被邀请在国际编辑委员会任职，并被邀请在顶级会议和大学发表演讲。我的探索助学金计划的一项重要使命是培养世界顶尖的热力学专家。我吸引优秀的加拿大和国际研究生和博士后研究员(HQP)，并为他们提供他们应得的全面培训和高质量的指导，使他们能够充分发挥潜力。我的HQP在学术界、政府和工业界都取得了突出的成就。**
