提案编号：0609062标题：NIRT：纳米尺度下基于纳米管的纳米流体设备和基础流体研究PI：Gogosi，Yury机构：德雷克塞尔大学本提案是对NSF 05-610类纳米尺度科学与工程倡议的响应。该项目建议开发基于有源纳米管的装置，用于基础研究直径从1到300纳米的纳米管和纳米管的圆柱形通道内的多相流体的行为。反过来，这些基础研究将使纳米流体器件的合理设计和优化成为可能，这些器件的运行依赖于流体传输和接近分子尺寸的相变。这项研究将与来自材料科学和工程、机械工程、电气工程和计算科学领域的六名教员一起，采用多学科和多机构(德雷克塞尔大学、宾夕法尼亚大学(宾夕法尼亚大学)、伊利诺伊大学芝加哥分校(UIC))的方法。这项工作将把研究人员在微制造、流体热物理、纳米结构碳材料、磁学和分子动力学方面的专业知识结合到一个协同计划中。拟议工作的主要目标是：(1)制造纳米管和中空纳米纤维，并改变其表面性质；(2)构建基于纳米管的装置，允许对液体发生的物理过程进行原位透射和扫描电子显微镜研究；(3)从实验和计算上解决纳米尺度流体物理中的基本问题；(4)使用基于纳米管的装置研究受限几何形状中的溶质-表面和液-液相互作用，并达到纳米级分辨率；(5)展示基于纳米管的有源器件的制造和使用，如细胞探针、纳米注射器、特定部位的药物输送系统、传感器和芯片工厂。在更广泛的影响方面，NIRT计划将鼓励本科生参与，并加强与行业的联系。提倡者将开发一个以高中实习为特色的教育项目，为本科生提供研究经验，并与一所欧洲顶尖大学进行学生/教师交流。本课程开发的研究成果和实验技术将整合到课堂教学中。

Proposal No.: 0609062Title: NIRT: Nanotube Based Nanofluidic Devices and Fundamental Fluid Studies at the NanoscalePI: Gogotsi, YuryInstitution: Drexel UniversityThis proposal was received in response to Nanoscale Science and Engineering initiative, NSF 05-610, category NIRT. This project proposes to develop active nanotube-based devices for fundamental studies of the behavior of multiphase fluids within cylindrical channels of nanotubes and nanopipes with diameters ranging from 1 to 300 nm. In turn, these fundamental studies will enable the rational design and optimization of nanofluidic devices whose operation relies on fluid transport and phase transitions at scales approaching molecular dimensions. This research will join six faculty members from the fields of materials science and engineering, mechanical engineering, electrical engineering, and computational science, in a multi-disciplinary and multi-institutional (Drexel University, University of Pennsylvania (Penn), University of Illinois at Chicago (UIC)) approach. The work will combine expertise of researchers in microfabrication, fluid thermophysics, nanostructured carbon materials, magnetism, and molecular dynamics into a synergistic program. The main objectives of the proposed work are: (1) Fabrication of nanotubes and hollow nanofibers, and modification of their surface properties; (2) Construction of nanotube-based devices that allow in situ transmission and scanning electron microscopy investigations of physical processes occurring liquids; (3) Addressing experimentally and computationally fundamental questions in nanoscale fluid physics; (4) Using nanotube-based devices to study solute-surface and liquid-liquid interactions in confined geometries, with nanoscale resolution; (5) Demonstrate the fabrication and use of nanotube-based active devices as cellular probes, nano-syringes, site-specific drug delivery systems, sensors, and a factory-on-a-chip. With respect to Broader Impacts, the NIRT program will encourage the involvement of undergraduate students and strengthen links with industry. The proposers will develop an education program featuring high-school internships, research experiences for undergraduates, and a student/faculty exchange with a leading European university. The research results and experimental techniques developed in this program will be integrated into classroom instruction.
