ABSTRACTPROPOSAL NO.: CTS-0348149PRINCIPAL INVESTIGATORS: K. SHARPINSTITUTION: PENNSYLVANIA STATE UNIVERSITYCAREER: PARTICLE EFFECTS IN MICROFLUIDICSThe research program consists primarily of an experimental study of the consequences and science underlying a particular subset of particle effects and particle transport in pressure-driven and electrokinetic micro fluidic systems. The specific flows of interest are those in which the particle diameter is of the same order of magnitude as the characteristic dimension of the characteristic micro fluidic device dimension. This regime traditionally has not been encountered in macroscale particle-laden flows, but is expected to gain importance for particle-based assay or micro/nano-fabrication applications given the continued efforts at device miniaturization. Over the longer term, the proposed research program will lay the groundwork for an expansion of scope, namely to include the study of nanoparticle transport in nanoscale systems. Broad impacts of the work include significant educational and outreach components. The proposed educational program aims to increase the participation of traditionally under-represented groups in science and engineering and, ultimately, related professions, by providing a unique environment for active discussion of the broader context of science and research. This program, entitled Expanding View will initially be designed around the broader issues of Micro and Nanoscale Science and Engineering and will be offered as an annual Seminar Course with administrative assistance from the Women in Engineering Program Office at Penn State. Through Expanding View, undergraduate students will have the opportunity to engage in team-oriented problem-solving coupled with effective mentoring and peer interactions, and participate in both on- and off-campus discussions of 'big-picture' topics such as the societal impact of research, the effects of public policy decisions on research directions, diversity in the workforce, and international competitiveness. *co-funded jointly by the Fluid Dynamics & Hydraulics, and Particulate and Multiphase Processes programs

PROPOSAL NO：CTS-0348149 PRINCIPAL调查员：K.SHARPINSTUTION：宾夕法尼亚州立大学：微流体中的粒子效应研究计划主要包括对压力驱动和电动微流体系统中粒子效应和粒子传输的特定子集的后果和科学的实验研究。感兴趣的特定流动是其中颗粒直径与特征微流控装置尺寸的特征尺寸具有相同数量级的流动。传统上，这一机制在大尺度颗粒流中并未遇到，但由于设备小型化的持续努力，预计将在基于颗粒的分析或微/纳米制造应用中获得重要地位。从长远来看，拟议的研究计划将为扩大范围奠定基础，即将纳米粒子在纳米系统中的传输研究包括在内。这项工作的广泛影响包括重要的教育和宣传部分。拟议的教育计划旨在通过提供一个独特的环境，让人们积极讨论更广泛的科学和研究背景，从而增加传统上代表性不足的群体在科学和工程领域以及最终相关职业中的参与。这项名为“拓展视野”的计划最初将围绕微纳科学和工程这一更广泛的问题进行设计，并将在宾夕法尼亚州立大学妇女参与工程计划办公室的行政协助下作为年度研讨会课程提供。通过扩展视野，本科生将有机会参与以团队为导向的问题解决以及有效的指导和同行互动，并参与校园内外关于研究的社会影响、公共政策决策对研究方向的影响、劳动力多样性和国际竞争力等“宏大”主题的讨论。*由流体动力学和流体力学以及颗粒和多相工艺项目共同资助
