we are 

Welcome to the Liu Group!
We are an interdisciplinary research group in the Department of Chemical & Biomolecular Engineering at Johns Hopkins University.
We aim to tackle challenges in energy and sustainability with better materials and electrochemical processes.

An electrochemically mediated gas gating mechanism


The regulation of mass transfer across membranes is central to a wide spectrum of applications.  We describe a previously unexplored gas gating mechanism driven by reversible electrochemical metal deposition & dissolution on a conductive membrane. The gating mechanism involves neither moving parts nor dead volume and can therefore enable various engineering processes.
