1. Development of the Metrology and Imaging of Cellulose Nanocrystals
Published: 9/19/2011
Authors: Michael T Postek, Andras Vladar, John A Dagata, Natalia Farkas, Bin Ming, Ryan Wagner, Arvind Raman, Robert J Moon, Ronald Sabo, Theodore H Wegner, James Beecher
Abstract: The development of metrology for nanoparticles is a significant challenge. Cellulose nanocrystals (CNC) are one group of nanoparticles that have high potential economic value but present substantial challenges to the development of the measurement ...

2. High-voltage Nanoimprint Lithography of Refractory Metal Film
Published: 7/1/2010
Authors: John A Dagata, Natalia Farkas, R Ramsier
Abstract: Local oxidation of metal, semiconductor, and polymer surfaces has provided a common basis from which to explore fundamental principles of nanolithography and prototype functional nanostructures for many years now. This article summarizes an investiga ...

3. Cellulose Nanocrystals the Next Big Nano-thing?
Published: 8/6/2008
Authors: Michael T Postek, Andras Vladar, John A Dagata, Natalia Farkas, Bin Ming, Ronald Sabo, Theodore H Wegner
Abstract: Biomass surrounds us from the smallest alga to the largest redwood tree. Even the largest trees owe their strength to a newly-appreciated class of nanomaterials known as cellulose nanocrystals (CNC). Cellulose, the world s most abundant natural, rene ...

4. Physical characterization methods for iron-oxide contrast agents encapsulated within a targeted liposome-based delivery system
Published: 4/16/2008
Authors: John A Dagata, Natalia Farkas, Cindi L Dennis, Robert D Shull, Vincent A Hackley, Charles W Yang, Kathleen F Pirollo, Esther H Chang
Abstract: Intact liposome-based targeted nanoparticle delivery systems (NDS) are immobilized by nonselective binding and characterized by scanning probe microscopy (SPM) in a fluid imaging environment. The size, size distribution, functionality, and stability ...

5. Nanoscale Oxidation of Zirconium Surfaces: Kinetics and Mechanisms
Published: 7/1/2003
Authors: Natalia Farkas, Li Zhang, E A Evans, R Ramsier, John A Dagata
Abstract: We show that AFM-induced oxide features can be reproducibly formed on both Zr and ZrN surfaces, and that the growth rate decreases rapidly with increasing time. There is an increase in oxide-feature height with humidity for both systems, and an appro ...
