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

摘要提案编号： CTS-0348149主要制造商：K.夏普机构： 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。 感兴趣的特定流是其中颗粒直径与特征微流体装置尺寸的特征尺寸具有相同数量级的那些。 这种制度传统上还没有遇到宏观尺度的颗粒负载流，但预计将获得重要性的颗粒为基础的测定或微/纳米制造应用装置小型化的持续努力。 从长远来看，拟议的研究计划将为扩大范围奠定基础，即包括纳米颗粒在纳米系统中的传输研究。 这项工作的广泛影响包括重要的教育和外联部分。 拟议的教育计划旨在通过提供一个独特的环境，积极讨论更广泛的科学和研究背景，增加传统上代表性不足的群体在科学和工程领域的参与，并最终增加相关专业的参与。 该计划名为“扩大视野”，最初将围绕微观和纳米科学与工程的更广泛问题进行设计，并将作为年度研讨会课程提供，并由宾夕法尼亚州立大学工程项目办公室的妇女提供行政援助。 通过拓展视野，本科生将有机会参与以团队为导向的问题解决，再加上有效的指导和同伴互动，并参与校内和校外的“大局”主题讨论，如研究的社会影响，公共政策决策对研究方向的影响，劳动力的多样性和国际竞争力。* 由流体动力学水力学、颗粒和多相过程项目共同资助
