ABSTRACT:  Molecular transport spanning multiple phases and drastically different length scales occurs in our daily life and controls our health and surrounding environment; such transport phenomena include greenhouse gas generation from combustion of fossil fuels and drug transport and delivery within the human body.

ABSTRACT:  Lattice Boltzmann methods, due to their amenability to parallelization and ability to handle geometrically complex boundaries, are appealing for simulating flows with particles, droplets, and bubbles when experimental observations and manipulations are not possible. This talk will present recent advances in the use of these methods for simulating droplet coalescence and particle motion in confined geometries.

ABSTRACT:  Thin porous materials are found in many critical applications such as battery and fuel cell electrodes, wound dressings, filtration membranes, fabrics and paper, to name a few.  The standard body of porous media techniques and theories have been developed for rock and soil pertaining to reservoirs and aquifers.  Consequently, studying transport processes in thin porous materials generally requires developing new approaches, both experimental and modeling. 

ABSTRACT:  Globe warming and energy security are two major challenges the world is facing today. To preserve our environment and energy resource, it is imperative to maximize the utilization of existing fuels while exploring renewable sources. Fuel cell and lithium metal battery as the next-generation high-efficiency energy conversion and storage devices have attracted a great deal of attentions in recent years. This presentation summarizes some recent progresses in my laboratory in these two research areas.
