Functionalized carbon nanotube thin-film nanocomposite membranes for water desalination applications
Cost-effective purification and desalination of water is a global challenge. Reverse osmosis (RO), the current method of choice, requires high pressure drops across the membranes in order to achieve acceptably high flow rates. Conventional polymer membranes are limited in their performance by a …

Selective molecular transport in nanopore systems
A detailed characterization of the physics of novel nanopore systems has the potential to revolutionize water filtration, nanofluidics, and biomolecule detection technologies. I give my characterizations of five nanopore systems as my dissertation. First, I present my study of nanopores in …
