Carbohydrate-Functionalized Surfactant Vesicles for Controlling Glycan Density

March 15, 2012
Author(s)
Monique A. Makos, Rebecca A. Zangmeister
We report on the development of a method for rapidly characterizing the glycan binding properties of lectins. Catanionic surfactant vesicles were prepared that spontaneously formed in water and remained stable at room temperature for months. By varying the

Environmental Metabolomics

March 15, 2012
Author(s)
Daniel W. Bearden
The application of metabolomics in the field of environmental science or ecology, which has developed based substantially on NMR spectroscopic approaches, is a fast paced, rapidly developing field which seems to be poised to help re-frame the discussion of

Coherent Dynamics of meta-Toluidine Investigated by QuasiElastic Neutron Scattering

March 14, 2012
Author(s)
Antonio Faraone, Kunlun Hong, Larry Kneller, Michael Ohl, John R. Copley
The coherent dynamics of a typical fragil glass former, meta-toluidine, was investigated at the molecular level using QuasiElastic Neutron Scattering, with Time-of-Flight and Neutron Spin Echo spectrometers. It is well known that the static structure

Tumor Necrosis Factor Interaction with Gold Nanoparticles

March 14, 2012
Author(s)
De-Hao D. Tsai, Sherrie R. Elzey, Frank W. DelRio, Robert I. MacCuspie, Suvajyoti S. Guha, Michael R. Zachariah, Athena M. Keene, Jeffrey D. Clogston, Vincent A. Hackley
We report on a systematic investigation of molecular conjugation of tumor necrosis factor protein-α (TNF) onto gold nanoparticles (AuNPs) and the subsequent binding behavior to its antibody (anti-TNF). We employ a combination of physical and spectroscopic

Developing Emergency Communication Strategies for Buildings

March 12, 2012
Author(s)
Erica D. Kuligowski, Steve M. Gwynne, Kathryn M. Butler, Bryan L. Hoskins, Carolyn Sandler
The purpose of this document is to provide the foundation for the development of a guidance document on emergency communication message content and dissemination strategies. The document answers three major questions regarding emergency communication

Electrospray – Differential Mobility Analysis as an Orthogonal Tool to Size Exclusion Chromatography for Characterization of Protein Aggregates

March 12, 2012
Author(s)
Suvajyoti S. Guha, Joshua R. Wayment, Michael J. Tarlov, Michael R. Zachariah
The biopharmaceutical industry characterizes and quantifies aggregation of protein therapeutics using multiple analytical techniques to cross validate results. Here we demonstrate the use of electrospray-differential mobility analysis (ES-DMA), a gas-phase

Broad bandwidth trace gas and standoff detection with infrared frequency comb sources

March 11, 2012
Author(s)
Nathan R. Newbury, Alexander M. Zolot, Esther Baumann, Fabrizio R. Giorgetta, Florian B. Adler, Ian R. Coddington, Kevin O. Knabe, Lora L. Nugent-Glandorf, Paul A. Williams, Scott A. Diddams, Tyler W. Neely
An optical frequency comb based on the output of a mode-locked femtosecond laser can be used in spectroscopic studies and sensing applications. The broad array of frequency modes simultaneously provides high spectral resolution and broad wavelength

The National Ballistics Imaging Comparison (NBIC) Project

March 10, 2012
Author(s)
Jun-Feng Song, Theodore V. Vorburger, Susan M. Ballou, Robert M. Thompson, James H. Yen, Thomas Brian Renegar, Xiaoyu Alan Zheng, Richard M. Silver, Martin Ols
In response to the guidelines issued by the ASCLD/LAB-International (American Society of Crime Laboratory Directors/Laboratory Accreditation Board) to establish traceability and quality assurance in U.S. crime laboratories, a NIST/ATF joint project

Traceable Calibration of a Critical Dimension Atomic Force Microscope

March 9, 2012
Author(s)
Ronald G. Dixson, Ndubuisi G. Orji, Craig D. McGray, John E. Bonevich, Jon C. Geist
The National Institute of Standards and Technology (NIST) has a multifaceted program in atomic force microscope (AFM) dimensional metrology. One component of this program, and the focus of this paper, is the use of critical dimension atomic force

An Evaluation of Local Shape Descriptors for 3D Shape Retrieval

March 8, 2012
Author(s)
Sarah Y. Tang
As the usage of 3D models increases, so does the importance of developing accurate 3D shape retrieval algorithms. Most prominently, shape descriptors are used to describe the geometric and topological properties of objects and compared to determine two

Graphing and Grafting Graphene: Classifying Finite Topological Defects

March 8, 2012
Author(s)
Eric J. Cockayne
The structure of finite-area topological defects in graphene is described in terms of both the direct honeycomb lattice and its dual triangular lattice. Such defects are equivalent to cutting out a patch of graphene and replacing it with a different patch

An Analysis of Solver-Based Simulation Tools

March 7, 2012
Author(s)
Ion Matei, Conrad E. Bock
Computer-interpretable representations of systems’ structure and behavior are at the center of designing today’s complex systems. Engineers create and review such representations using (graphical) modeling languages that support specification, analysis

Friedel-like Oscillations from Interstitial Iron in Superconducting Fe 1+y Te 0.62 Se 0.38

March 7, 2012
Author(s)
V. Thampy, J. Kang, Jose Rodriguez Rivera, W. Bao, A. T. Savici, J. Hu, T. J. Liu, B. Qian, D. Fobes, Z. Q. Mao, C. B. Fu, Wangchun Chen, Q. Ye, Ross Erwin, Thomas R. Gentile, Z. Tesanovic, Collin L. Broholm
Using polarized and unpolarized neutron scattering we show that interstital Fe in superconducting Fe 1=yTe 1-xSe x induces a magnetic Friedel-like oscillation that idffracts at Q = (1⁄20) and involves greater than}50 neighboring Fe sites. The interstitial

Optical microscope angular illumination analysis

March 7, 2012
Author(s)
Ravikiran Attota
For high precision applications of optical microscopes, it is critical to achieve symmetrical angular illumination intensity at the sample plane, in addition to uniform spatial intensity achieved by Köhler illumination. In this paper, first we demonstrate
