Electronic Enhancement of the Exciton Coherence Time in Charged Quantum Dots

October 19, 2015
Author(s)
Galan A. Moody, Corey A. McDonald, Ari D. Feldman, Todd E. Harvey, Richard P. Mirin, Kevin L. Silverman
Minimizing decoherence due to coupling of a quantum system to its fluctuating environment is at the forefront of quantum information and photonics research. Nature sets the ultimate limit, however, given by the strength of the system’s coupling to the

Protection of Controlled Unclassified Information

October 19, 2015
Author(s)
Ronald S. Ross, Kelley L. Dempsey, Larry Feldman, Gregory A. Witte
This bulletin summarizes the information presented in NIST SP 800-171: Protecting Controlled Unclassified Information in Nonfederal Information Systems and Organizations. The publication the protection of Controlled Unclassified Information (CUI) while

The NIST IAD Data Science Research Program

October 19, 2015
Author(s)
Bonnie J. Dorr, Peter C. Fontana, Craig S. Greenberg, Mark A. Przybocki, Marion Le Bras, Cathryn A. Ploehn, Oleg Aulov, Martial Michel, Edmond J. Golden III, Wo L. Chang
We examine foundational issues in data science including current challenges, basic research questions, and expected advances, as the basis for a new Data Science Research Program and evaluation series, introduced by the Information Access Division of the

Optical-to-RF Frequency Synthesis: Application Priorities for Ultra-low Phase Noise

October 18, 2015
Author(s)
David A. Howe, Archita Hati, Craig W. Nelson, Lora L. Nugent-Glandorf
We describe operational challenges and progress of optical frequency-comb dividers (OFDs) that synthesize RF signals from the optical domain. Our priorities include: (1) ultra-low phase-noise, (2) continuous operation, and (3) broadly low Allan deviation.

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

A Single-Pixel Touchless Laser Tracker Probe

October 15, 2015
Author(s)
Josh Gordon, David R. Novotny, Alexandra Curtin
We have developed a laser tracker probe, the Pixel Probe, that does not require physically contacting the object one is measuring and which has 3D spatial resolution of about 25 μm (in x,y,z) in the current configuration. This touchless laser tracker probe

NIST on a Chip: Realizing SI units with microfabricated alkali vapour cells

October 16, 2015
Author(s)
John E. Kitching, Elizabeth A. Donley, Svenja A. Knappe, Matthew T. Hummon, Argyrios Dellis, Jeffrey A. Sherman, Kartik A. Srinivasan, Vladimir A. Aksyuk, Qiliang Li, Daron A. Westly, Brian J. Roxworthy, Amit Lal
We describe several ways in which microfabricated alkali atom vapour cells might potentially be used to accurately realize a variety of SI units, including the second, the meter, the kelvin, the ampere and the volt, in a compact, low-cost “chip-scale”

Quantifying Trace 2,4,6-Trinitrotoluene (TNT) in Polymer Microspheres

October 16, 2015
Author(s)
Timothy M. Brewer, Robert A. Fletcher, Matthew E. Staymates
Well characterized test materials are essential for validating the performance of current trace explosive detection systems. Explosive encapsulated microspheres have proven to be a valuable test material for trace explosive detection because their precise
