The project entails the fundamental study of condensation phase change on nanoengineered surfaces, covered with an ultrathin hydrophobic or super-hydrophobic coating. A significant outcome of the project is the possibility of engineering or "designing" better (more resilient) surfaces. The study has potential to impact several industries, such as power utilities, heating ventilation and air-conditioning equipment, electronic devices, and desalination systems. The main objective is to determine the surface coating defects formation, degradation and nucleation dynamics during condensation, which is key to enhancing longevity and heat transfer effectiveness of the surface. A new advanced scanning probe microscopy technique will be utilized for process visualization. Educational effort is very broad, involving research experience activities for k-12 teachers and students, new laboratory activities for undergraduate engineering students, and a new graduate course.

该项目需要对覆盖着超薄疏水或超疏水涂层的纳米工程表面的凝聚相变进行基础研究。该项目的一个重要成果是有可能设计或“设计”更好(更有弹性)的表面。这项研究可能会影响几个行业，如电力公用事业、供暖通风和空调设备、电子设备和海水淡化系统。主要目的是确定冷凝过程中表面涂层缺陷的形成、降解和成核动力学，这是提高表面寿命和传热效果的关键。一种新的先进的扫描探针显微镜技术将被用于过程可视化。教育工作非常广泛，包括为K-12教师和学生提供的研究体验活动，为本科工程专业学生提供的新的实验室活动，以及一门新的研究生课程。
