The fascinating nature of nanoengineered materials has opened the door to novel approaches for conducting research in the field of nanoscale energy conversion and cooling technology. This project creates new fundamental knowledge about nanoscale radiative heat transfer, needed to solve pressing problems in energy harnessing, conversion and cooling. The ability to manipulate, suppress and tune the radiative properties of nanoscale objects becomes essential in diverse areas like solar and thermophotovoltaic energy conversion, waste heat recovery, and potential energy savings by radiative cooling. The characterization of low-cost, highly effective thermal nanomaterials is necessary for basic scientific thermal research and industrial production. Given the potential of these technologies, there is a need to attract talent and generate interest in young minds. The project establishes, supports, and nurtures an environment that encourages nanoengineering entrepreneurship and leadership and exposes high school students to small scale heat transfer technologies to get hands-on experience about nanomaterials and solve real-world societal and global energy challenges. Hands-on NanoEngineering workshops are to be conducted in partnership with local high schools to increase the quantity and quality of students, especially minorities and women.This project aims to conduct a comprehensive study relevant to nanoscale radiative thermal transport due to photonic metamaterials in both far-field and near-field regimes. The objective of this project is to better understand the physics of radiative thermal transport at the nanometer scale, focusing mainly on thermal, optical and unique combinations of these properties of nanostructured materials. It includes three research tasks: (1) explore novel nanomaterials using computational methods and advanced spectroscopy techniques, (2) manipulate thermal radiative wavelength selectivity in near-field and far-field regimes, and (3) demonstrate photonic metamaterials-based thermophotovoltaic energy conversion and radiative cooling. The knowledge gap will be closed between nanoscale thermal transport and radiative wavelength selectivity which attributes to the enhanced thermal infrared energy harvesting, conversion, and photon-based cooling, both necessitate exploring interdisciplinary engineering discoveries and approaches when these technologies in the areas of thermal transport processes and nanoengineering are combined to function as an integrative energy system.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

纳米工程材料的引人入胜的性质为在纳米级能量转换和冷却技术领域进行研究的新方法打开了大门。该项目创建了有关纳米级辐射传热的新基本知识，这些知识是为解决施加能量施加，转换和冷却的压力问题所需的。在太阳能和嗜热伏洛伏型能量转换，废热恢复以及通过辐射冷却来节省的各个区域，操纵，抑制和调整纳米级物体的辐射特性的能力变得至关重要。低成本，高效的热纳米材料的表征对于基本的科学热研究和工业生产是必需的。鉴于这些技术的潜力，有必要吸引人才并对年轻人产生兴趣。该项目建立，支持和培育一个鼓励纳米工程企业家精神和领导力的环境，并使高中生接触小型传热技术，以获得有关纳米材料的动手经验，并解决现实世界中的社会和全球能源挑战。动手纳米工程研讨会应与当地高中合作进行，以增加学生的数量和质量，尤其是少数群体和妇女。该项目旨在进行与纳米级辐射热运输有关的全面研究，这是由于远场和近场政府的光子造型而引起的。该项目的目的是更好地了解纳米级辐射热传输的物理学，主要集中在纳米结构材料的这些特性的热，光学和独特组合上。它包括三个研究任务：（1）使用计算方法和先进的光谱技术探索新型纳米材料，（2）操纵近场和远场状态的热辐射波长选择性，（3）证明基于光子 - 材料的热型热电驾驶仪能量转换和辐射性冷却。知识差距将在纳米级的热传输和辐射波长的选择性之间封闭，这将增强的热红外能量收集，转换和基于光子的冷却归因于跨学科的工程发现和方法，当这些技术在热运输过程和统计型统计的领域中，这些技术和纳米统计信息是整体上的启发，并将其作为整体统计数据的功能。认为值得通过基金会的智力优点和更广泛影响的评论标准来评估值得支持。
