Other(s)

    • Development of the Thermodynamic Toolkit (TTK), a C++ code package for addressing phase stability, thermodynamics and phase diagrams of multicomponent alloy systems via the cluster expansion methodology.
    • Recent applications of TTK to nanosystems and catalyst design:
      • Identification of stable structures of bimetallic nanoparticles and the effect of alloy composition on hydrogen evolution rate.
      • Identification of stable structures in semiconductor nanowires and band structure/gap characteristics versus alloy compositions.
      • Study of adsorbate coverage on catalyst surface during electrochemical hydrogen evolution.
    • Researchers interested in using TTK in their field, please drop me an email for further discussions.
    • Looking for students to apply TTK to energy related applications: (i) Solar harvesting (ii) Li/Na ion batteries (iii) Hydrogen fuel cell reactions. Potential students may apply to work with me via the AGS or SINGA scholarship (graduate level) or via the various internship opportunities (undergraduate level) in A-STAR.
