1. Dimensional Reduction of Duplex DNA Under Nanofluidic Slit Confinement
Published: 8/19/2015
Authors: Luis Fernando Vargas Lara, Jack F Douglas, Samuel M Stavis, Elizabeth A Strychalski, Jon C Geist, Brian Joseph Nablo
Abstract: There has been much recent interest in the dimensional properties of duplex DNA under nanoscale confinement conditions as a problem of fundamental interest in both technological and biological fields. This has led to a series of measurements by f ...

2. Confronting the Complexity of Commercial Carbon Nanotube Materials
Published: 5/13/2015
Authors: Luis Fernando Vargas Lara, Jack F Douglas
Abstract: The morphology of commercially available carbon nanotube materials is often much more complex than the term ,carbon nanotubeŠ (CNT) would imply. Commercial CNT materials are typically composed of roughly spherical CNT domains having a highly rami ...

3. Interplay of particle shape and suspension properties: a study of cube-like particles
Published: 3/20/2015
Authors: Debra Jean Audus, Ahmed M. Hassan, Edward Joseph Garboczi, Jack F Douglas
Abstract: With advances in anisotropic particle synthesis, particle shape is now a feasible parameter for tuning suspension properties. However, there is a need to determine how these newly synthesized particles affect suspension properties and a need to solve ...

4. Critical Examination of the Colloidal Particle Model of Globular Proteins
Published: 2/3/2015
Authors: Prasad Srinivasan Sarangapani, Steven D Hudson, Ronald Leland Jones, Jack F Douglas, Jai Avinash Pathak
Abstract: Recent studies of globular protein solutions have uniformly adopted a colloidal view of proteins as particles, a perspective that neglects the polymeric primary structure of these biological macromolecules, their intrinsic flexibility and their abi ...

5. High-speed, high-purity separation of gold nanoparticle‹DNA origami constructs using centrifugation
Published: 7/23/2014
Authors: Seung H. Ko, Luis Fernando Vargas Lara, Paul N. Patrone, Samuel M Stavis, Francis Starr, Jack F Douglas, James Alexander Liddle
Abstract: DNA origami is a powerful platform for assembling gold nanoparticle constructs, an important class of nanostructure with numerous applications. Such constructs are assembled by the association of complementary DNA oligomers. These association reactio ...

6. Three Dimensional Cluster Distributions in Processed Multi-wall Carbon Nanotube Polymer Composites
Published: 6/25/2014
Authors: Doyoung Moon, Jan Obrzut, Jack F Douglas, Thomas F. Lam, Krzysztof Koziol, Kalman D Migler
Abstract: We determine the three-dimensional structure of melt-mixed carbon nanotube networks in an amorphous polymer via confocal microscopy and image analysis. We find that the CNTs networks consist of ramified clusters whose size distribution scales with cl ...

7. Resonant Microwave Absorption in Thermally Deposited Au Nanoparticle Films Near Percolation Coverage
Published: 6/19/2013
Authors: Jan Obrzut, Jack F Douglas, Oleg A Kirillov, Fred Sharifi, James Alexander Liddle
Abstract: We observe a resonant transition in microwave absorption in thin thermally deposited Au nanoparticle films near the geometrical percolation transition pc where the films exhibit a ,fractal‰ heterogeneous geometry. The absorption of incident microwa ...

8. Rippling Instability of Supported Polymer Nanolines
Published: 2/21/2012
Authors: Vijaya R. Tirumala, Christopher M Stafford, Leonidas E. Ocola, Jack F Douglas, L. Mahadevan
Abstract: The swelling response of polymer line gratings supported on a rigid substrate has direct implications on their mechanical stability during pattern transfer in nanofabrication. The polymer lines, when swollen in a good solvent, undergo a rippling inst ...

9. Using Block Copolymer Self-Assembly to Imprint the Crystallization of Polymer Dendrites
Published: 8/10/2011
Authors: Sangcheol Kim, Alamgir Karim, Jack F Douglas, Christopher L Soles, R M Briber
Abstract: We utilize the self-assembly of cylinder-forming block copolymer (BCP) films to create templates for dendritic polymer crystallization patterns. This templating was achieved by simply spin-casting thin films from a solution containing both the BC ...

10. Flexure-induced structural and electronic changes in polymer supported membranes of length purified single-wall carbon nanotubes
Published: 2/22/2011
Authors: John M. Harris, Ganjigunte R.S. Iyer, Daneesh O. Simien, Jeffrey A Fagan, JiYeon Huh, Jun Y. Chung, Steven D Hudson, Jan Obrzut, Jack F Douglas, Christopher M Stafford, Erik K Hobbie
Abstract: Thin membranes of length purified single-wall carbon nanotubes (SWCNTs) are uniaxially compressed by depositing them on prestretched polymer substrates. Upon release of the strain, the topography, microstructure and conductivity of the films are c ...
