The focus of chemical engineering has shifted over the past three decades from macroscopic processes to include advanced materials, environmental protection, biomedical engineering, and microelectronics. This change in focus requires significant renovation for Chemical Engineering Thermodynamics, a required course in standard undergraduate chemical engineering curricula. At present, the thermodynamics courses mainly cover introductory materials and background followed by standard applications for classical chemical industries. While these topics remain useful, they do not reflect important developments in applied chemical thermodynamics since (about) 1975. Currently available textbooks are very good but, while they address important aspects of classical engineering, they do not give adequate attention to application of new thermodynamics, i.e., thermodynamic developments of the last 30 (or so) years. The objective of this work is to contribute toward bringing undergraduate and graduate education in Chemical Engineering Thermodynamics into the twenty-first century. Toward that end, chemical engineering educators need comprehensive descriptions of "new" thermodynamics illustrated with specific examples of applications suitable for undergraduates and beginning graduates. This project will create educational materials (a new textbook with interactive software and classroom problems) that introduce modern topics in applied statistical thermodynamics and molecular simulations. This project was initiated about eight years ago with a two-year award from NSF. The PI and co-PI have prepared a draft for most chapters of the new text, and this award will allow for completion.Intellectual Merit: The contemplated textbook supplements, modernizes, and updates Chemical Engineering Thermodynamics courses by showing a variety of realistic examples for emerging areas of chemical engineering. It covers only "modern" thermodynamics, that is, chemical engineering applications of statistical mechanics including molecular simulations. Thenew text will be distinguished from similar books in physics or chemistry by emphasizing the engineering relevance and the physical (as opposed to mathematical) basis of statistical thermodynamics. Special attention is given to "high-tech" applications of complex systems, including colloids, polymer solutions or blends, thin films, surfactants, and bio-macromolecules. To complement the textbook, free-to-access websites will be developed to provide mathematical details of statistical-mechanical theories and computer programs for molecular simulations.Broader Impact: In the US, about 4000 undergraduate students per year take one or two courses in Chemical Engineering Thermodynamics. At least one course in Chemical Engineering Thermodynamics is required for the BS degree. Introduction of the basic principles of statistical thermodynamics and molecular simulations in undergraduate thermodynamics classes will benefit not only those students who are interested in molecular modeling but also those who plan to work on development and production of advanced materials or those who plan a career in biotechnology or environmental engineering. By creating learning materials and effective teaching and assessing strategies, this work will provide innovative solutions to some of the most challenging problems in undergraduate education in chemical engineering.

在过去的三十年里，化学工程的重点已经从宏观过程转向先进材料、环境保护、生物医学工程和微电子学。这种重点的转变需要对化学工程热力学进行重大改革，这是标准本科化学工程课程的必修课。目前，热力学课程主要涵盖入门材料和背景，然后是经典化学工业的标准应用。虽然这些主题仍然有用，但它们并没有反映自 1975 年以来应用化学热力学的重要发展。目前可用的教科书非常好，但虽然它们解决了经典工程的重要方面，但没有对新热力学的应用给予足够的关注，即过去 30 年（左右）的热力学发展。这项工作的目标是将化学工程热力学的本科生和研究生教育带入二十一世纪。为此，化学工程教育工作者需要对“新”热力学进行全面的描述，并附有适合本科生和刚毕业的研究生的具体应用示例。该项目将创建教育材料（一本带有交互式软件和课堂问题的新教科书），介绍应用统计热力学和分子模拟的现代主题。该项目大约在八年前启动，并获得了 NSF 的两年资助。 PI 和 co-PI 已经为新文本的大部分章节准备了草稿，该奖项将允许完成。 智力优点：预期的教科书通过展示各种现实例子来补充、现代化和更新化学工程热力学课程。化学工程新兴领域。它仅涵盖“现代”热力学，即统计力学的化学工程应用，包括分子模拟。新教材将通过强调统计热力学的工程相关性和物理（而不是数学）基础来与物理或化学领域的类似书籍区分开来。特别关注复杂系统的“高科技”应用，包括胶体、聚合物溶液或混合物、薄膜、表面活性剂和生物大分子。为了补充教科书，将开发免费访问网站，提供统计力学理论和分子模拟计算机程序的数学详细信息。更广泛的影响：在美国，每年大约 4000 名本科生选修一到两门化学课程工程热力学。学士学位至少需要一门化学工程热力学课程。在本科生热力学课程中介绍统计热力学和分子模拟的基本原理，不仅对那些对分子建模感兴趣的学生有益，而且对那些计划从事先进材料的开发和生产或计划从事生物技术或生物技术的学生有益。环境工程。通过创建学习材料以及有效的教学和评估策略，这项工作将为化学工程本科教育中一些最具挑战性的问题提供创新的解决方案。
