SHREC'09 Track: Generic Shape Retrieval

March 29, 2009
Author(s)
Afzal A. Godil, Helin Dutagaci
In this paper we present the results of the SHREC 09- Generic Shape Retrieval Contest. The aim of this track was to evaluate the performances of various 3D shape retrieval algorithms on the NIST generic shape benchmark. We hope that the NIST shape

Optical detection of NMR J -spectra at zero magnetic field

March 28, 2009
Author(s)
M Ledbetter, C.W. Crawford, A Pines, D.E. Wemmer, Svenja A. Knappe, John Kitching, D Budker
Nuclear magnetic resonance (NMR) has emerged as one of the most powerful analytical tools for elucidating molecular structure. One of the parameters typically extracted from NMR spectra which is necessary to fully understand the structure of a molecule is

Low-temperature plasma assisted nanotransfer printing between thermoplastic polymers

March 26, 2009
Author(s)
Deuk Y. Lee, Daniel R. Hines, Christopher Stafford, Christopher Soles, Eric K. Lin, Gottlieb Oehrlein
we performed a survey of the factors controlling the changes of the adhesion characteristics for PMMA and PET surfaces upon plasma activation of the respective interfaces for nanotransfer printing. Polar active functional groups introduced by plasma

Controlling the Formation and Orientation of Terraced Nanoscale Ribbons of a Thiophene-Based Copolymer

March 24, 2009
Author(s)
Dean M. DeLongchamp, Regis J. Kline, Youngsuk Jung, David Germack, Eric K. Lin, Andrew Moad, Lee J. Richter, Michael F. Toney, Martin Heeney, Iain McCulloch
Terraced nanoscale ribbon domains of a poly(2,5-bis(3-alkylthiophen-2-yl) thieno[3,2-b]thiophene) form after thin films are cooled from its highest-temperature phase. A simple flow coating procedure can induce high levels of ribbon orientation and even

Major Applications of Electrochemical Techniques at National Metrology Institute

March 24, 2009
Author(s)
M Mariassy, Kenneth W. Pratt, Petra Spitzer
A review of the state of the art of electrochemical methods at the highest metrological level in National Metrology Institutes (NMIs) in given, with emphasis on standardization work (primary methods) in the fields of pH and electrolytic conductivity, as

Dielectric Spectroscopy Investigation of Relaxation in C60-Polyisoprene Nanocomposites

March 23, 2009
Author(s)
Yifu Ding, Sebastian Pawlus, Alexei Sokolov, Jack F. Douglas, Alamgir Karim, Christopher Soles
We investigate the influence of adding C60 nanoparticles on the dielectric relaxation spectra of both unentangled and entangled polyisoprene (PIP). Relaxation modes corresponding to both segmental and chain relaxation were analyzed over a broad temperature

Electromagnetic Emissions and Performance for Proximity RFID

March 23, 2009
Author(s)
Jeffrey R. Guerrieri, David R. Novotny, Michael H. Francis, Catherine A. Remley
We examined the electromagnetic emissions, and performance of commercial High-Frequency (HF) proximity Radio Frequency Identification (RFID) systems including their susceptibility to jamming and eavesdropping. These proximity RFID systems are used in an

Examination of thin film modulus for a series of poly(alkyl methacrylates)

March 22, 2009
Author(s)
Jessica M. Torres, Christopher Stafford, Bryan D. Vogt
In this work, the modulus of polymer thin films for a homologous series of poly(n-alkyl methacrylate)s will be discussed. In particular, the impact of the degree of undercooling from bulk Tg on the deviations will be explored as Tg is significantly

Surviving Insecure IT: Effective Patch Management

March 21, 2009
Author(s)
Simon Liu, D. Richard Kuhn, Hart Rossman
The amount of time to protect enterprise systems against potential vulnerability continues to shrink. Enterprises need an effective patch management mechanism to survive the insecure IT environment. Effective patch management is a systematic and repeatable

Uncertainties in Scaling Factors for ab Initio Vibrational Zero-Point Energies

March 21, 2009
Author(s)
Karl K. Irikura, Russell D. Johnson III, Raghu N. Kacker, Ruediger Kessel
Vibrational zero-point energies (ZPEs) determined from ab initio calculations are often scaled by empirical factors. An empirical scaling factor partially compensates for the effects arising from vibrational anharmonicity and incomplete treatment of

A transmitter for calibrating the extinction ratio of optical receivers

March 20, 2009
Author(s)
Jeffrey A. Jargon, Xiaoxia Wu, Paul D. Hale, Klaus M. Engenhardt, Alan Willner
We describe a transmitter being developed at the National Institute of Standards and Technology for calibrating extinction ratio measurements of optical receivers. Preliminary measurement results are presented, and major uncertainty components are

Exposure of Epitaxial Graphene on SiC(0001) to Atomic Hydrogen

March 20, 2009
Author(s)
N Guisinger, Gregory M. Rutter, Jason Crain, Phillip N. First, Joseph A. Stroscio
The realization of graphene-based electronics involves numerous challenges that include large-scale device fabrication and the ability to control the electronic properties of the graphene material1. As a nearly ideal 2D conductor, the electronic properties
