Sub-nanometer pores in two-dimensional materials for nanofluidics, sensing and energy applications
Material Measurement Laboratory, Applied Chemicals and Materials Division
Please note: This Agency only participates in the February and August reviews.
Recent advances in fabrication make solid sub-nanometer pores in two-dimensional (2D) materials a reality. Such pores, often resulting from merely a dozen or so atomic sites ejected from the host 2D lattice, promise to revolutionize a diverse range of applied areas, including water desalination, biomolecule sensing, and power generation.
Our group at NIST has recently started a collaboration with UC Berkeley, Lawrence Berkeley National Laboratory, and Lawrence Livermore National Laboratory aimed at investigating 2D sub-nm pores with properties engineered at the atomic level for specific applications. Qualified candidates are encouraged to propose theoretical and computational projects focused on the fundamental and applied topics involving solid-state 2D sub-nm pores, listed as follows:
- Ionic and molecular transport through sub-nm pores in boron nitride, transition metal dichalcogenides, graphene, and other 2D materials.
- Chemically inert (self-passivated) solid nanopores.
- Highly selective nanopores for efficient osmotic power generation.
- Nanopore-based sensing of biomolecules, including DNA and denatured proteins.
- Mechanosensitive and streaming ionic transport.
- Water desalination and salinity control.
- Nanofluidic logic elements.
We also welcome proposals on related topics not specifically listed above.
