Nanoengineered materials have exciting, untapped potential to improve energy and water technologies. In this talk, I provide a few examples of how we leverage nanoscale manipulation capabilities to develop advanced thermal management, solar thermal energy conversion and water harvesting devices. First, I discuss our recent work that harnesses novel surface designs to control and manipulate wettability and liquid-vapor phase-change processes. We demonstrated high flux evaporation from ultra-thin nanoporous membranes and nanostructured surfaces that can repel liquids even during condensation. Next, I discuss how nanoengineered materials such as optically transparent thermally insulating aerogels can be used to increase the efficiency of solar thermal devices. Finally, I present a water harvesting device that leverages the unique properties of metal organic frameworks and other adsorbents to address water scarcity challenges in arid climates.
纳米工程材料在改善能源和水的技术方面极具开发潜力。在本次演讲中，我将通过几个例子来说明我们如何利用纳米级操作能力来开发先进的热能管理、太阳能热能转换和水收集设备。首先，我将讨论我们最近的工作，利用新的表面设计来控制和操纵润湿性和汽液相变过程。我们证明了超薄纳米孔膜和纳米结构表面的高通量蒸发，即使在凝结过程中也能排斥液体。接下来，我将讨论如何使用纳米工程材料，如光学透明隔热气凝胶来提高太阳能热器件的效率。最后，我将介绍一种利用金属有机框架和其他吸附剂的独特特性来解决干旱气候下缺水问题的集水装置。
