thin films, surfaces, and nano-engineering
Advanced nanometer–scale thin films have applications in optics, microelectronic systems, protective coatings, selective permeation and gas barrier layers, photovoltaic energy conversion devices, quantum well structures, and many others.
We are working to extend ALD into new and expanding areas, including Molecular Layer Deposition, where the chemical concepts of ALD are utilized for atomic–level integration of organic monomer and molecular building blocks into well defined thin films.
A new and growing focus is on modification of high surface area 3D structures, including nonwoven fibrous mats and natural and synthesized fabric structures for energy conversion devices, biological integration or separation systems.
Berc Kalanyan successfully defended his Ph.D. on 12/15/2014. Berc was co-advised by Dr. Michael Dickey. Congratulations to Berc and best of luck as he transitions into a Postdoc role at NIST in Spring of 2015.
Dr. Gregory Parsons, Alcoa Professor of Chemical and Biomolecular Engineering and director of the Nanotechnology Initiative at North Carolina State University, has been selected as the 30 recipient of the R.J. Reynolds Tobacco Company Award for Excellence in Teaching, Research and Extension. Parsons delivered an award lecture Monday, Nov. 24, at the Larry K. Monteith Engineering Research Center on NC State’s Centennial Campus. His lecture was entitled “Understanding Thin Film Materials: Deflecting Pauli’s Devil.”

Under funding from NIH, Our group has been working with Jamie Bonner in Toxicology, and we recently found that thin ALD layers on carbon nanotubes modify their toxicity. See the related news releases from NIEHS and from NC State.
Project description on Grants.gov Under support from NSF's Scalalbe Nanomanufacturing program, Parsons' group is currently exploring large-scale high throughput roll-to-roll atomic layer deposition, specifically for enabling low-cost conformal and uniform coatings on fibers and fibrous surfaces.
Barry Hiney was an undergrad researcher in our group for several years, and he left in 2012 to join the Peace Corp and work in Burkina. Follow his adventures by clicking here.
