Nanocatalyst shape and composition during nucleation of single-walled carbon nanotubes

December 7, 2015

Author(s)

Jose Gomez-Ballesteros, Juan Burgos, Pin A. Lin, Renu Sharma, Perla Balbuena

The dynamic evolution of nanocatalyst particle shape and carbon composition is examined through the initial stages of the single walled-carbon nanotubes chemical vapor deposition synthesis via classical reactive and ab initio molecular dynamics simulations

Intrinsic Conductivity of Carbon Nanotubes and Graphene Sheets Having a Realistic Geometry

November 23, 2015

Author(s)

Luis Fernando Vargas Lara, Ahmed M. Hassan, Edward J. Garboczi, Jack F. Douglas

The addition of carbon nanotubes (CNTs) and graphene sheets (GSs) into polymeric materials such as epoxy resins can greatly enhance the conductivity and alter the electromagnetic response of the resulting nanocomposite material. The extent of these

Layered Double Hydroxide-Based Fire Re-sistant Coatings for Flexible Polyurethane Foam

November 5, 2015

Author(s)

Yu-Chin Li, John R. Shields, Rick D. Davis

Montmorillonite clay (MMT) is frequently used to create fire resistance in Layer-by-Layer (LbL) applied coatings. This manuscript reports that switching the MMT with layered double hydroxides (LDH) produced a more effective fire resistant coating on

ROLE OF SALT ON ADHESION OF AN EPOXY/ALUMINUM (OXIDE) INTERFACE IN AQUEOUS ENVIRONMENTS

November 5, 2015

Author(s)

Kar T. Tan, Christopher C. White, Donald L. Hunston, Justin M. Gorham, Michael Imburgia, Aaron M. Forster, Vogt D. Bryan

Engineering joints consisting of polymer/inorganic interfaces are commonly exposed to less than ideal conditions during normal service; these environmental conditions present a significant challenge for maintaining the structural integrity of the interface

Making Contact to Molecular Layers: Linking Large Ensembles of Molecules to the Outside World

November 4, 2015

Author(s)

Christina A. Hacker, Sujitra J. Pookpanratana, Curt A. Richter, Mariona Coll

In this chapter we examine the various approaches to making electrical contact to large area molecular junctions. We will highlight the experimental concerns that one must consider and the various approaches to make reliable structures and characterize the

Distributions of a Linear Homopolymer Additive in an Ordered Block Copolymer Matrix as Quantified by Small Angle Neutron Scattering

October 27, 2015

Author(s)

Huagen H. Peng, Vikram Daga, Ying Lin, J J. Watkins, Wen-Li Wu, Christopher Soles

The addition of linear poly (acrylic acid) (PAA) to a disordered low molecular mass poly (ethylene oxide)-poly (propylene oxide)-poly (ethylene oxide) triblock copolymer host (PEO-b-PPO-b-PEO) is known to induce an ordering transition. Small angle neutron

Nanoporous Silicon Combusion: Observation of Shockwave and Flame Synthesis of Nanoparticle Silicon Oxide

October 26, 2015

Author(s)

John G. Gillen, Collin Becker, Conrad Stoldt, Matthew E. Staymates

The persistent hydrogen termination present in nanoporous silicon (nPS) is unique compared to other forms of nanoscale silicon (Si) which typically readily form a silicon dioxide passivation layer. The hydrogen terminated surface combined with the

Detecting Carbon in Carbon: Application of Differential Charging to Obtain Information on the Chemical Identity and Spatial Location of Carbon Nanotube Aggregates in Composites by Imaging X-ray Photoelectron Spectroscopy

October 24, 2015

Author(s)

Justin M. Gorham, William A. Osborn, Jeremiah W. Woodcock, Keana C. Scott, John M. Heddleston, Angela R. Hight Walker, Jeffrey W. Gilman

The surface contributions and dispersion properties of multiwalled carbon nanotubes (MWCNT) within a composite are important measurements to perform on nano-enabled products in order to help answer environmental health and safety questions associated with

Applied Strain on Sealant Samples Exposed to Outdoor Weather

October 19, 2015

Author(s)

Christopher C. White, Donald L. Hunston, Kar tean Tan

In outdoor exposures used to establish durability of sealant formulations, applied strain is typically absent. It is a critical aspect of the in-service environment. This research employs two recently available techniques to examine how the presence of

Equilibrium Self-Assembly, Structure, and Dynamics of Clusters of Star-Like Micelles

October 17, 2015

Author(s)

Vivek M. Prabhu, Shrinivas Venkataraman, Yi Yan Yang, James Hedrick

Small-angle neutron scattering and static and dynamic light scattering have characterized the hierar-chical structure and dynamics of clusters of self-assembled star-like micelles formed by oligocarbonate-fluorene func-tionalized polyethylene glycol

Mid-infrared spectroscopy beyond the diffraction limit via direct measurement of photothermal effect

September 30, 2015

Author(s)

Aaron M. Katzenmeyer, Glenn E. Holland, Jungseok Chae, Alan H. Band, Kevin Kjoller, Andrea Centrone

An atomic force microscope equipped with temperature sensitive probes was used to measure locally the photothermal effect induced by IR light absorption. This novel instrument opens a pathway to correlated topographical, chemical composition, and thermal

Metal-Dielectric-Metal Resonators with Deep Subwavelength Dielectric Layers Increase the Near-Field SEIRA Enhancement

September 24, 2015

Author(s)

Jungseok Chae, Basudev Lahiri, John M. Kohoutek, Glenn Holland, Henri Lezec, Andrea Centrone

Plasmonic nanostructures presenting either structural asymmetry or metal-dielectric-metal (M-D-M) architecture are commonly used structures to increase the quality factor and the near-field confinement in plasmonic materials. This characteristic can be
