NSF East Asia and Pacific Summer Institute for FY 2012 in Japan

这项行动资助卡内基梅隆大学的Scott N. Schiffres于2012年夏天在日本东京本古的东京大学开展一项研究项目，题为“纳米粒子在融化-冻结过程中增强热传递并应用于太阳能热能储存”。东道主科学家是丸山茂雄和盐美俊一郎。该研究项目的智力价值在于研究纳米尺寸的颗粒，如碳纳米管和石墨烯，如何影响相变材料的导热性。除了表征纳米级颗粒悬浮液的其他方面外，还使用金属涂层纤维3-omega技术表征纳米级颗粒相变材料的导热性。这项研究的一个应用是了解纳米颗粒如何在融化和冻结过程中增强传热，从而增强热储存并减少能源使用。EAPSI奖学金的广泛影响包括为研究员提供美国以外的第一手研究经验；介绍该地区的科学、科学政策和科学基础设施；以及对社会、文化和语言的了解。这些活动符合美国国家科学基金会的目标，即在其科学家、工程师和教育工作者的职业生涯早期培养国际合作，从而确保美国科学劳动力具有全球意识。

This action funds Scott N. Schiffres of Carnegie Mellon University to conduct a research project, entitled "Nano-sized particles to enhance heat transfer in melting-freezing with applications to solar thermal energy storage," during the summer of 2012 at the University of Tokyo in Hongo, Tokyo, Japan. The host scientists are Shigeo Maruyama and Junichiro Shiomi.The Intellectual Merit of the research project lies in the study of how nano-sized particles, such as carbon nanotubes and graphene, influence thermal conductivity in materials undergoing phase-change. A metal coated fiber 3-omega technique is being used to characterize thermal conductivity of the phase-change material with nano-sized particles in addition to characertizing other aspects of the nano-sized particle suspension. One application of this research is to understand how nano-particles may enhance heat transfer during melting and freezing, allowing for enhanced thermal storage and reduced energy usage. The Broader Impacts of an EAPSI fellowship include providing the Fellow a first-hand research experience outside the U.S.; an introduction to the science, science policy, and scientific infrastructure of the respective location; and an orientation to the society, culture and language. These activities meet the NSF goal to educate for international collaborations early in the career of its scientists, engineers, and educators, thus ensuring a globally aware U.S. scientific workforce.
