Since 2010, I am dedicated my research efforts to the computational design of novel materials and the exploration of their thermo-electro-mechanical properties through theoretical modeling and atomistic simulations. Specifically, my team is actively engaged in fundamental research on fluid dynamics and nanofluidics.

Tailoring catalytically active sites in an layer by layer  fashion affords a highly porous material that exhibits excellent trifunctional electrocatalytic activities toward the hydrogen evolution reaction (ηj=10 = 116 mV), oxygen evolution reaction (ηj=10 = 254 mV), as well as oxygen reduction reaction (half-wave potential = 0.75 V vs reference hydrogen electrode) in alkaline solutions. The dispersion-corrected density functional theory calculations suggest that the prominent catalytic activity of the layer by layer MOF toward the HER, OER, and ORR is due to the initial negative adsorption energy of water on the metal nodes and the elongated O–H bond length of the H2O molecule.

Our molecular dynamics simulations reveal the strong sensitivity of the shear viscosity of confined water to the size of the confining channel. Increasing the channel size, even by as little as 1 Å, results in changes of the shear viscosity by more than an order of magnitude. Distinct layering of water confined between the graphene layers is apparent only for particular channel sizes. ACS Nano 10,3,3685-3692 (2016)
