1335946PrakashThe over-arching goal of this proposal is to provide transformative advances towards developing a nanofluidic pump inspired by principles of active pumping from biology and engineered nanofluidics. In this proof-of-concept project, an attempt will be made to establish electrokinetic aqueous electrolyte transport in a confined nanochannel in the presence of asymmetric surface charges on the channel walls. The experiments will be guided by computational models (both continuum and molecular dynamics) to engineer a proof-of-concept, novel, nanofluidic pump. The idea is based on well-established ideas in biological systems that use asymmetric charges to move hydrated ions and combine with a nanofluidic device with embedded electrodes to develop a novel nanofluidic pump. Since, no such system has been built before this proposal presents high risk, potentially transformative research. This work will have significant impact on advances in nanoscale fluid dynamics leading to new avenues for engineering novel nanofluidic devices for a variety of applications as described in the main proposal narrative. By using multi-stage integration between research and education, this multi-disciplinary experimental project is expected to give at a minimum undergraduate and graduate students and perhaps a much broader audience including minority, under-represented groups, middle and high school female students exposure to microfluidics and nanofluidics through individual and group lab training, coursework, hands-on workshops, outreach, and web modules for impact on education of future scientists and engineers.

1335946Prakash该提案的首要目标是提供变革性的进展，以开发受生物学和工程纳米流体主动泵送原理启发的纳米流体泵。在这个概念验证项目中，将尝试建立在一个封闭的纳米通道中的不对称表面电荷的存在下，在通道壁上的电动电解质水溶液的运输。这些实验将由计算模型（连续介质和分子动力学）指导，以设计一种概念验证的新型纳米流体泵。这个想法是基于生物系统中已经确立的想法，即使用不对称电荷来移动水合离子，并将其与具有嵌入式电极的纳米流体装置联合收割机结合，以开发一种新型的纳米流体泵。因为，在这项提议提出高风险、潜在的变革性研究之前，还没有建立这样的系统。这项工作将产生重大影响，在纳米流体动力学的进展，导致工程新的纳米流体设备的各种应用中所描述的主要建议叙述的新途径。通过使用研究和教育之间的多阶段整合，这个多学科的实验项目预计将至少给本科生和研究生，也许更广泛的观众，包括少数民族，代表性不足的群体，初中和高中女生接触微流体和纳米流体通过个人和小组实验室培训，课程，动手研讨会，推广，以及对未来科学家和工程师教育产生影响的网络模块。
