Materials for gas separation

  1. Important for chemical industry

  2. Sorbents and membranes are most commonly used

  3. We study local interaction of gas and separation media with quantum chemistry

  4. We model solubility and diffusivity with molecular simulations including Monte Carlo and molecular dynamics

Uranium extraction chemistry

  1. Sea has almost unlimited supply of U despite its low concentration.

  2. Fiber sorbent with task-specific groups can fish out U from the sea

  3. We use MD simulations at QM, MM, and QM/MM levels to study the complexation chemistry under the high salinity condition of seawater.

Electric energy storage

  1. Broad applications in transportation, electronics, and robotics

  2. We work on supercapacitors, including double-layer and pseudo capacitors

  3. We use joint DFT to study the charging behaviors of different materials including advanced carbons

Current Research Topics:

  1. Nanocatalysis: Nanoclusters, oxides, 2D materials, ceramics

  2. Porous and liquid materials for gas separation

  3. Electrical energy storage and solid/liquid interfaces

  4. Uranium speciation and extraction

Important challenges in nanocatalysis

  1. Convert abundant small molecules to fuels and value-added chemicals

  2. We use electronic structure methods such as DFT coupled with transition-state search to understand and predict catalytic pathways

  3. Catalysts of special interest include gold nanoclusters, 2D materials, transition-metal oxides, and bimetallic materials

Moore’s Law Meets Materials Chemistry via Quantum Mechanics and Classical Mechanics. We aim to address the following materials chemistry challenges with computational tools.
