Broadening Participation through a Workshop on Nanoengineered Surfaces for Thermal Energy Transport

相变传热在许多工业过程中都是理想的，包括海水淡化，太阳能热能储存，电化学能量储存和电子冷却。在过去的几十年里，纳米科学在开发新的工程表面以提高相变传热过程的热力学效率方面发挥了至关重要的作用。虽然纳米工程表面已经成为能源存储的关键技术，但纳米科学教育是一种新兴的、相对不发达的技术。因此，开发新颖有效的方法向学生传授纳米科学的概念，以继续推进纳米技术的发展是非常重要的。该项目旨在通过探索工程表面的润湿性特征及其对多相系统的影响来解决这些问题。通过研讨会形式，K-12学生将学习纳米工程表面和多相传热的概念。在工作坊期间，学生还将参加研讨会和实验室参观，并进行实验室实验。其目标是激励学生追求科学、技术、工程和数学（STEM）领域的教育和职业，并传达表面工程在解决未来问题中的重要性。该项目的预期结果是，在芯片开发中提高对新型蒸发冷却技术的认识，并在制造服务器或电力电子设备等系统时提高相应的冷却挑战。项目团队将与华盛顿大学的地方外展项目合作，包括学术管道项目，以招募经济资源有限的学生参加研讨会。本次研讨会的重点是通过让未被充分代表的少数民族和妇女接触纳米技术的跨学科领域，来解决扩大STEM领域的参与问题。研讨会的另一个成果是为教师创建了一个课堂模块，用于实验证明纳米工程表面对热传输的重要性。此外，该项目将与学校伙伴关系研究所（ISP）合作，该研究所是华盛顿大学的标志性努力，旨在改善K-12教育社区的教学和学习，开发和交付课堂模块。

Phase change heat transfer is desirable in many industrial processes including water desalination, solar thermal energy storage, electrochemical energy storage, and electronics cooling. Over the last several decades, nanoscience has played a crucial role in the development of novel engineered surfaces for improving the thermodynamic efficiency of phase change heat transfer processes. While nanoengineered surfaces has become a critical technology for energy storage, nanoscience education is new and relatively underdeveloped. It is therefore important to develop novel and effective methods for teaching the concepts of nanoscience to students to continue the advancement of nanotechnology. The project seeks to address these issues with exploring the concepts of wettability characteristics of engineered surfaces and effects on multiphase systems. Through a workshop format, K-12 students will learn about the concepts of nanoengineered surfaces and multi-phase heat transfer. During the workshop, students will also participate in seminars and laboratory tours and conduct laboratory experiments. The goal is to inspire the students to pursue education and careers in science, technology, engineering, and mathematics (STEM) fields as well as convey the importance of surface engineering in solving future problems. An anticipated outcome of the project is to increase the awareness of novel evaporative cooling technology in development of chips and corresponding cooling challenges as one proceeds to make systems such as servers or power electronics devices. The project team will work with local outreach programs from Washington University including the Academic Pipeline programs to recruit students with few financial resources to participate in the workshop. The focus of this workshop is to address broadening participation in STEM fields by exposing underrepresented minorities and women to the interdisciplinary field of nanotechnology. An additional outcome of the workshop is the creation of a classroom module for teachers to use to experimentally demonstrate the importance of nanoengineered surfaces on thermal transport. Further, the project will collaborate with the Institute for School Partnership (ISP), is Washington University's signature effort to improve teaching and learning strategically within the K-12 education community, to develop and deliver the classroom module.
