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热力学许多分支的深刻掌握方面的国际公认的记录，以提供理解，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。多组分、多相系统（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，熔化/固化，蒸发/冷凝），将通过这项研究解决发生在几乎每一个制造业，自然资源和能源行业;是新的表面，微流体和纳米技术的基础;是中央复杂的过程中的环境;也是现代科学的焦点虽然有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，但最正确的工作只针对相对不复杂的系统。拟议的研究将在三个主要目标下解决许多当前悬而未决的问题：1）为广泛的工业，科学和环境重要的多相系统提供平衡热力学，这些系统由曲率和其他界面现象主导。2)发展非平衡态热力学方法来描述非理想多组分系统中界面处的传质，并求解各种几何形状和实验环境下的界面传输、相邻体相传输和热传输的耦合方程。3)将理论预测与我们小组和其他领先实验室的基础实验进行比较，以验证和完善理论。这项工作的长期影响将是推进现代热力学，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。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。我的研究已经得到了六个国家奖项的认可，邀请担任国际编辑委员会，并邀请在顶级会议和大学演讲。我的探索基金项目的一个重要使命就是培养世界顶尖的考古学家。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监督，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杰出的成就。
