At LAS, we are developing novel two-dimensional (2-d) nanoporous materials and membranes using a number of material platforms including graphene, carbon nitrides, metal-organic frameworks (MOFs), and silicates. Overall, we are engineering large-area, nm-thick films with with a precise control of nanopore size and functionality.  In the next few years, LAS will pursue:

  1. Synthesis for two-dimensional nanoporous materials by atomic layer deposition (ALD), chemical vapor deposition (CVD), hydrothermal synthesis, exfoliation, etc.
  2. Elucidation of crystal growth mechanism.
  3. Study of thin, high throughput membranes and membrane reactors.
  4. Elucidation of molecular transport mechanism.
