Invariant ionic conductance in an atomically thin polar nanopore
Shengping Zhang, Haiou Zeng, Ningran Wu +11
Ion channels regulate many essential properties of biological cells, especially the membrane potential. Despite decades of efforts on artificial channels, it remains a great challe…
Molecular Valves for Controlling Gas Phase Transport Made from Discrete Angstrom-Sized Pores in Graphene
Luda Wang, Lee W. Drahushuk, Lauren Cantley +5
An ability to precisely regulate the quantity and location of molecular flux is of value in applications such as nanoscale 3D printing, catalysis, and sensor design. Barrier materi…
Observation of Pull-in Instability in Graphene Membranes under Interfacial Forces
Xinghui Liu, Narasimha G. Boddeti, Mariah R. Szpunar +6
We present a unique experimental configuration that allows us to determine the interfacial forces on nearly parallel plates made from the thinnest possible mechanical structures, s…
Selective Molecular Sieving through Porous Graphene
Steven P. Koenig, Luda Wang, John Pellegrino +1
Membranes act as selective barriers and play an important role in processes such as cellular compartmentalization and industrial-scale chemical and gas purification. The ideal memb…
Ultrathin Oxide Films by Atomic Layer Deposition on Graphene
Luda Wang, Jonathan J. Travis, Andrew S. Cavanagh +5
In this paper, a method is presented to create and characterize mechanically robust, free standing, ultrathin, oxide films with controlled, nanometer-scale thickness using Atomic L…
