项目摘要
This EAGER award will investigate coupled processes in an active nanoporous membrane resulting from cyclic mechanical deformation. Electrostatic and hydrodynamic interactions in the hyperboloidal nanopore due to variable pore geometry in the presence of ahydrodynamic pressure gradient will be studied to explore ion rejection and increased water flux through the membrane due to mechanical oscillations. Specific quesitons to be addressed include: What is/are the (i) limiting geometrical, electrostatic and hydrodynamic conditions for ion rejection and water flux; (ii) fabrication constraints in manufacturing a hyperboloidal nanopore and (iii) relationship between water flux, ion rejection, amplitude and the duty cycle of the applied signal. The proposed research will for the first time investigate the applicability of elastic deformation of nanopores for an engineering function and mimic the functionality of cell membrane proteins. The proposed concept, if successful, will lead to a new class of membranes that can be programmed to separate various ions and species through controlled operation.If successful this research work will make significant contributions to the fields of active materials, membrane mechanics and provide fundamental understanding of active processes in nanopores. The fundamental understanding of ion transport processes through an active nanopore will lead to innovative applications in chemical separations and biomedical applications. The scientific knowledge gained from this work will be disseminated through presentations in Materials Research Society meetings and the scientific data will be made available to the general public through the PI's lab webpage. The research effort of this award will be further enhanced by engaging undergraduate students in Mechanical and Aerospace Engineering department at The Ohio State University on developing design rules for a desalination system. Further, relevancy of this research program to desalination, the ongoing social trend towards environmental sustainability will motivate undergraduate students to take up advanced engineering courses and certainly attract them to pursue graduate program in engineering.
这个热切的奖项将研究由循环机械变形导致的活性纳米孔膜中的耦合过程。我们将研究在非动压梯度作用下,双曲面纳米孔中由于不同的孔道几何形状而产生的静电和流体相互作用,以探索由于机械振荡而引起的离子截留和通过膜的水通量增加。需要解决的具体问题包括:(1)限制离子截留和水通量的几何、静电和流体动力学条件;(2)制造双曲面纳米孔的制造限制;(3)水通量、离子截留、振幅和施加信号的占空比之间的关系。这项拟议的研究将首次探索纳米孔弹性变形对工程功能的适用性,并模拟细胞膜蛋白质的功能。如果成功,这一概念将导致一类新的膜,它可以通过可控操作来编程分离不同的离子和物种。如果成功,这项研究工作将对活性材料、膜力学领域做出重大贡献,并提供对纳米孔中活性过程的基本理解。对通过活性纳米孔的离子传输过程的基本了解将导致在化学分离和生物医学应用方面的创新应用。从这项工作中获得的科学知识将通过在材料研究会会议上的陈述进行传播,并将通过国际和平研究所的实验室网页向公众提供科学数据。该奖项的研究工作将进一步加强,俄亥俄州立大学机械和航空航天工程系的本科生将参与开发海水淡化系统的设计规则。此外,这项研究计划与海水淡化的相关性,以及持续的环境可持续发展社会趋势,将激励本科生学习高级工程课程,并肯定会吸引他们攻读工程学研究生课程。
