AWARD ABSTRACT0933510McGaughey This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5).A persistent need exists to develop novel materials that may advance the thermal management of various engineering devices such as microelectronics circuitry. This proposal deals with the development of a lightweight, high thermal conductivity rigid porous material that is formed of a network of fused carbon nanotubes. The resulting material could be attached to various heat generating devices, and liquid coolants could be passed through the porous matrix, resulting in significantly enhanced cooling of the device.Intellectual Merit: The proposed material is to be fabricated of fused carbon nanotubes. Measurements of the thermal conductivity and permeability of the rigid matrix will be made to determine how these properties vary with the structure of the matrix. Models will be developed to predict the phonon transfer within the carbon nanotube network, and how the transfer is affected by the molecules of the fluid that flows through the matrix. Finally, models will be developed to predict the permeability of the matrix, and its effectiveness in serving as a thermal management material. A multidisciplinary team of investigators with backgrounds in Mechanical Engineering, Chemical Engineering, and Materials Science and Engineering will be involved in the fabrication, experimentation, and modeling of the multiscale thermal transport phenomena.Broader Impact: The proposed research is expected to lead to new, lightweight materials for thermal management of a wide range of devices. A lecture series on nanoscale materials is proposed for inclusion in the undergraduate curriculum. The lectures will be dovetailed with current classes, and an assessment strategy will determine the efficacy of the effort. In Pittsburgh, a program to excite middle school girls about engineering, involving hands on workshops for the students is proposed. Girls from underrepresented groups are targeted. A similar workshop, involving the Society of Women Engineers is proposed for Ann Arbor.

奖项 摘要0933510McGaughey 该奖项根据 2009 年美国复苏和再投资法案（公法 111-5）提供资金。人们一直需要开发新型材料，以促进微电子电路等各种工程设备的热管理。该提案涉及开发一种轻质、高导热率的刚性多孔材料，该材料由熔融碳纳米管网络形成。由此产生的材料可以附着在各种发热设备上，并且液体冷却剂可以通过多孔基体，从而显着增强设备的冷却。 智力优点：所提出的材料由熔融碳纳米管制成。将测量刚性基体的导热率和渗透性，以确定这些特性如何随基体结构变化。将开发模型来预测碳纳米管网络内的声子传递，以及流经基质的流体分子如何影响传递。最后，将开发模型来预测基质的渗透性及其作为热管理材料的有效性。具有机械工程、化学工程、材料科学与工程背景的多学科研究人员团队将参与多尺度热传输现象的制造、实验和建模。更广泛的影响：这项研究预计将产生用于各种设备热管理的新型轻质材料。建议将纳米材料系列讲座纳入本科课程。讲座将与当前课程相结合，评估策略将决定工作的有效性。在匹兹堡，一项旨在激发中学生对工程学的兴趣的计划被提议，其中包括为学生举办实践研讨会。来自代表性不足群体的女孩成为目标。建议在安娜堡举办一个由女工程师协会参加的类似研讨会。
