SUMMARY:Environmental and Energy Applications of Graphene Oxide Nanoarchit

DESCRIPTION:This talk presents two methods to control the interlayer spaci
 ng of ultrathin graphene oxide (GO) laminates on the nm-scale and discuss 
 their potential environmental and energy applications. The first method in
 volves Langmuir-Blodgett deposition and a novel 2D phase analysis techniqu
 e to control GO laminate wrinkle height between 1-20 nm. Wrinkles act as a
  spacer preventing face-to-face aggregation\, which improves the specific 
 capacitance of 3D electrodes. The second method involves vacuum filtration
  followed by UV\, HI\, or ultrasound reduction to control GO laminate nano
 channel dimensions on the Angstrom-scale. The nanochannel dimension determ
 ines the permeability and selectivity\, which makes it a versatile membran
 e material.
