Summary of report content:
Particles such as electrons and atoms/ions carry mass or information in motion, which can be used to conduct mass, energy transfer, and computational tasks. Liquids under nanoconfinement could be more structured than their bulk counterpart with disordered molecular structures. The newly arising orders reduces the entropy of molecular and ionic species and can be used to accommodate a few states of configuration. Combined with the diminishing boundary friction at atomistically smooth walls such as graphene, the dynamics of solution molecules and solved ions can be controlled and manipulated with low energy cost. In this talk, I will show how the molecular structures and dynamics of ion solvation is renormalized under nanoconfinement, and how the paired configuration of cations and anions are used to construct nanofluidic computers.
Brief introduction of the reporter:
Dr. Zhiping Xu received his bachelor and doctorate degrees from Tsinghua University in 2002 and 2007 , respectively. After that, he worked as a postdoctoral researcher at Rice University (2007-2008) and Massachusetts Institute of Technology (2008-2010) , and worked in aerospace at Tsinghua University since 2010 . School of Aeronautics, currently a professor in the Department of Engineering Mechanics. Dr. Xu Zhiping's current research interests are (1) micro- and nano-scale matter and energy transport processes; (2) material growth, microstructure evolution dynamics and service behavior.
