Wang, J. Wang, C. Zhang
The direct search for dark matter is entering a period of increased sensitivity to the hypothetical Weakly Interacting Massive Particle (WIMP). One such technology that is being examined is a scintillationonly noble liquid experiment, MiniCLEAN. MiniCLEAN

Electromagnetic Field Test Structure Chip for Back End of the Line Metrology

March 23, 2015
Author(s)
Lin You, Jungjoon Ahn, Emily Hitz, Jonathon Michelson, Yaw S. Obeng, Joseph J. Kopanski
A test chip to produce known and controllable gradients of surface potential and magnetic field at the chip surface and suitable for imaging with various types of scanning probe microscopes is presented. The purpose of the test chip is to evaluate various

The Testing Program at NIST on Fibers Used in Soft Body Armor Applications

March 21, 2015
Author(s)
Walter G. McDonough, Amanda L. Forster, Jae Hyun Kim, Nathanael A. Heckert, Joy P. Dunkers, Scott A. Wight, Gale A. Holmes
The goal of this paper and presentation is to give an update of the research effort to date being conducted at the National Institute of Standards and Technology (NIST) on polymeric fibers used in soft body armor with a special emphasis on new fibers under

Interplay of particle shape and suspension properties: a study of cube-like particles

March 20, 2015
Author(s)
Debra J. Audus, Ahmed M. Hassan, Edward J. Garboczi, Jack F. Douglas
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 the

A perspective on the use of nanomaterial categorization for risk assessment and regulatory decision-making

March 19, 2015
Author(s)
Hilary Godwin, Catherine Nameth, David Avery, Lynn Bergeson, Elizabeth Beryt, Wlliam Boyd, Amy Clippinger, Christine Hendren, Patricia Holden, Keith Houck, Agnes Kane, Frederick Klaessig, Tong Kooi Lee, Iseult Lynch, Timothy Malloy, Mary Miller, Gunter Oberdorster, Elijah Petersen, Vicki Stone, Andre Nel
For nanotechnology to meet its potential as a revolutionary and sustainable technology, it is necessary that engineered nanomaterials (ENMs) and nano-enabled products that are safe and effective make it to the marketplace. This process is frequently

Guidance for Secure Authorization of Mobile Applications in the Corporate Environment

March 19, 2015
Author(s)
Athanasios T. Karygiannis, Stephen Quirolgico, Larry Feldman, Gregory A. Witte
This bulletin provides an overview of NIST Special Publication (SP) 800-163, "Vetting the Security of Mobile Applications." The NIST SP helps organizations understand the process for vetting the security of mobile applications, plan for the implementation

Optimizing Hybrid Metrology: Rigorous Implementation of Bayesian and Combined Regression

March 19, 2015
Author(s)
Mark Alexander Henn, Richard M. Silver, Nien F. Zhang, Hui Zhou, Bryan M. Barnes, Bin Ming, Andras Vladar, John S. Villarrubia
Hybrid metrology, e.g. the combination of several measurement techniques to determine critical dimensions, is an important approach to meet the needs of semiconductor industry. A proper use of hybrid metrology may not only yield more reliable estimates for

Detection and characterization of nonspecific, sparsely-populated binding modes for conformational selection in the early stages of complexation

March 18, 2015
Author(s)
Antonio Cardone, Aaron Bornstein, Harish C. Pant, Mary C. Brady, Ram D. Sriram, Sergio Hassan
A method is proposed to study protein-ligand binding in a system governed by specific and non-specific interactions. Strong associations lead to narrow conformational distributions in the proteins configuration space; weak and ultra-weak associations lead

Field Measurement of Ventilation Rates

March 18, 2015
Author(s)
Andrew K. Persily
Ventilation rates have significant impacts on building energy use and indoor contaminant concentrations, making them key parameters in evaluating building performance. Ventilation rates have been measured in buildings for many decades and there are mature

High-Fidelity, Weak-Light Polarization Gate Using Room-Temperature Atomic Vapor

March 18, 2015
Author(s)
Lu Deng, Edward W. Hagley, Runbing Li, Chengjie Zhu
Using a polarization-selective-Kerr-phase-shift technique we demonstrate a fast, all-optical, high-fidelity polarization gate in a room-temperature atomic medium. By writing a pi-phase shift to one selected circularly-polarized component of a linearly

Light-wave mixing and scattering with quantum gases

March 18, 2015
Author(s)
Lu Deng, Edward W. Hagley, C.J. Zhu
We show that optical processes originating from elementary excitations with dominant collective atomic recoil motion in a quantum gas can profoundly change many nonlinear optical processes routinely observed in a normal gas. Not only multi-photon wave

Preparation and Separation of DNA-Wrapped Carbon Nanotubes

March 18, 2015
Author(s)
Geyou Ao, Ming Zheng
Purification of single-chirality single-wall carbon nanotubes (SWCNTs)from their synthetic mixture is a prerequisite for many applications. DNA-controlled carbon nanotube (CNT) purification has evolved over a decade along with other separation techniques

Redox sorting of carbon nanotubes

March 17, 2015
Author(s)
Hui Gui, Jason K. Streit, Jeffrey Fagan, Angela R. Hight Walker, Chongwu Zhou, Ming Zheng
This work expands the redox chemistry of single-wall carbon nanotube (SWCNT) by investigating its role in a number of SWCNT sorting processes. Using a polyethylene glycol (PEG)/dextran (DX) aqueous two-phase system, we show that electron-transfer reaction
