Disordered Nanoparticle Interfaces for Defect-Tolerant Self-Assembly

November 17, 2008
Author(s)
Kevin G. Yager, Brian Berry, Kirt A. Page, Derek L. Patton, Alamgir Karim, Eric J. Amis
Self-assembly is a promising route for controlling the nanoscale structure and material properties of coatings, yet it remains difficult to control the microstructure of these systems. In particular, self-assembling materials typically have complex and

Preparation and Characterization of Patchy Particles

November 14, 2008
Author(s)
Thuy Chastek, Steven D. Hudson, Vincent A. Hackley
The self-assembled organization of partilces depends on the symmetry of their interactions, and strides are being made in producing nanoaparticles of controlled shape and functionalization. This paper describes the use of particles adsorption to control

Centrifugal Length Separation of Carbon Nanotubes

October 1, 2008
Author(s)
Jeffrey A. Fagan, Matthew Becker, Jae H. Chun, Barry J. Bauer, Jeffrey R. Simpson, Angela R. Hight Walker, Erik K. Hobbie
Separation of single wall carbon nanotubes (SWCNTs) by length via centrifugation in a high density medium, and the characterization of both the separated fractions and the centrifugation process are presented. Significant quantities of the separated SWCNTs

Quantifying Changes in the Fast Dynamics of Mixtures by Dielectric Spectroscopy

September 26, 2008
Author(s)
Tatiana Psurek, Christopher L. Soles, Kirt A. Page, Marcus T. Cicerone, Jack F. Douglas
The addition of a solvent or nanoparticles to a polymeric material can lead toappreciable changes in the rates of relaxation and reaction that can profoundly alter material properties and function. We introduce a general theoretical strategy for

Multi-sample micro-slit rheometry

September 17, 2008
Author(s)
Doyoung Moon, Anthony J. Bur, Kalman D. Migler
We have developed a multi-sample micro-slit rheometer MMR which is capable of measurements over a broad range of temperatures, viscosities and shear rates. The instrument is mechanically simple as the flow is generated by external gas pressure and the
