1. Synapsable quadruplex-mediated fibers
Topic: Nanostructured Materials
Published: 5/3/2013
Authors: Veronika A Szalai, Miguel Angel Mendez
Abstract: We have fabricated and characterized a novel DNA based nanofiber created by synergistic self-assembly of guanine quadruplex (Hoogsteen base pairing) and double-stranded DNA (Watson-Crick base pairing). The assembly of our nanofibers occurs in several ...

2. Effect of AlN Buffer Layer Properties on the Morphology and Polarity of GaN Nanowires Grown by Molecular Beam Epitaxy
Topic: Nanostructured Materials
Published: 9/8/2011
Authors: Matthew David Brubaker, Kristine A Bertness, Norman A Sanford, Albert Davydov, Igor Levin, Devin M. Rourke, Victor M. Bright
Abstract: Low temperature AlN buffer layers grown by plasma-assisted Molecular Beam Epitaxy (MBE) on Si (111) were found to significantly affect the subsequent growth morphology of GaN nanowires. The AlN buffer layers exhibited nanowire-like columnar protrusi ...

3. Report on an Interlaboratory Study for the Measurement of BET-Specific Surface Area using an Industrially Relevant TiO2 Nanopowder
Topic: Nanostructured Materials
Published: 8/3/2011
Author: Vincent A Hackley
Abstract: This report summarizes the findings of an interlaboratory study (ILS) conducted in 2009-2010 under the auspices of the Versailles Project on Advanced Materials and Standards (VAMAS) Technical Working Area (TWA) 34 (Nanoparticle Populations). The stat ...

4. O2 A-band line parameters to support atmospheric remote sensing. Part II: The rare isotopologues
Topic: Nanostructured Materials
Published: 7/21/2011
Authors: Joseph Terence Hodges, David A Long, Daniel K Havey, S. S. Yu, M Okumura, Charles E Miller
Abstract: Frequency-stabilized cavity ring-down spectroscopy (FS-CRDS) was employed to measure over 100 transitions in the R-branch of the b1Σg+←X3Σg-(0,0) band for the rare O2 isotopologues. The use of 17O- and 18O-enriched mixtures allowed fo ...

5. Hydrodynamic Fractionation of Finite Size Nano Gold Clusters
Topic: Nanostructured Materials
Published: 6/15/2011
Authors: De-Hao Tsai, Tae Joon Cho, Frank W DelRio, Julian S. Taurozzi, Michael Russel Zachariah, Vincent A Hackley
Abstract: We demonstrate a high resolution in situ experimental method for performing simultaneous size-classification and characterization of functional nanoscale gold clusters (NGCs) based on asymmetric-flow field flow fractionation (AFFF). Field emission sc ...

6. Revealing the Interphase in Polymer Nanocomposites
Topic: Nanostructured Materials
Published: 3/16/2011
Authors: Mauro Zammarano, Paul Hutsell Maupin, Li Piin Sung, Jeffrey W Gilman, Douglas Matthew Fox
Abstract: Morphological characterization of polymer nanocomposites is a fundamental challenge that is complicated by multiple length scales. Here, we report a technique for high-throughput monitoring of interphase and dispersion in polymer nanocomposites based ...

7. Contact Resistance of Flexible, Transparent Carbon Nanotube Films with Metals
Topic: Nanostructured Materials
Published: 10/7/2010
Authors: Hua Xu, Lei Chen, Liangbing Hu, Nikolai B Zhitenev
Abstract: We studied the contact properties of different metals to flexible optically-transparent single-walled carbon nanotube (SWCNTs) films. The SWCNT films are deposited on flexible polyethylene terephthalate (PET) substrate and patterned in test structure ...

8. Very black infrared detector from vertically aligned carbon nanotubes and electric-field poling of lithium tantalate
Topic: Nanostructured Materials
Published: 8/3/2010
Authors: John H Lehman, Aric Warner Sanders, Leonard M Hanssen, Boris Hannes Wilthan, Jinan Zeng, Christopher Jensen
Abstract: Vertically aligned multiwall carbon nanotubes were grown by water-assisted chemical vapor deposition on a large-area lithium tantalate pyroelectric detector. The processing parameters are nominally identical to those by which others have achieved the ...

9. Effects of disorder and internal dynamics on vortex wall propagation
Topic: Nanostructured Materials
Published: 5/26/2010
Authors: Hongki Min, Robert D McMichael, Michael J Donahue, Jacques Miltat, Mark D Stiles
Abstract: Experimental measurements of domain wall propagation are typically interpreted by comparison to ideal models that ignore the effects of extrinsic disorder and the internal dynamics of domain wall structures. Using micromagnetic simulations we study v ...
