Detecting Paired and Counterflow superfluidity via dipole oscillations

Author(s)
Anzi A. Hu, Ludwig G. Mathey, Eite Tiesinga, Ippei Danshita, Carl J. Williams, Charles W. Clark
We suggest an experimentally feasible procedure to observe paired and counterflow superfluidity in ultra-cold atom systems. We study the time evolution of one...

Nanoscale Focused Ion Beam from Laser-cooled Lithium Atoms

Author(s)
Brenton J. Knuffman, Adam V. Steele, Jon Orloff, Jabez J. McClelland
To advance the capabilities of focused ion beam (FIB) technology, we have created a low-energy FIB from photoionized lithium atoms collected in a magneto...

Adjustable Zero Thermal Expansion in Antiperovskite Manganese Nitride

Author(s)
Xiaoyan Song, Zhonghua Sun, Qingzhen Huang, Markus Rettenmayr, Xuemei Liu, Martin Seyring, Guannan Li, Guanghui Rao, Fuxing Yin
The zero thermal expansion (ZTE) behavior particularly with a wide operating temperature range in a single material is extremely uncommon. With the clear...

Homoepitaxial n-core: p-shell gallium nitride nanowires: HVPE overgrowth growth on MBE nanowires

Author(s)
Aric Sanders, Paul T. Blanchard, Kristine A. Bertness, Matthew D. Brubaker, Ann Chiaramonti Debay, Christopher M. Dodson, Todd E. Harvey, Andrew M. Herrero, Devin M. Rourke, John B. Schlager, Norman Sanford, Albert Davydov, Abhishek Motayed, Denis Tsvetkov
We present the homoepitaxial growth of p-type, magnesium-doped gallium nitride shells using halide vapor phase epitaxy on n-type gallium nitride nanowires grown...

Engineering Organometallic Femtosecond Chemistry: Photochemistry and Dynamics of Ultrafast Chelation of Cyclopentadienylmanganese Tricarbonyl Derivatives with Pendant Benzenecarbonyl and Pyridinecarbonyl Groups

Author(s)
Edwin J. Heilweil, Jermaine O. Johnson, Karen L. Mosley, Phillipe P. Lubet, Webster E. Charles, T J. Burkey
A new method was developed to prepare three cyclopentadienyl manganese tricarbonyl derivatives 1, 4, and 5 with different side chains (Mn{ 5-C5H4CH2COR}(CO)3, R...

Security Automation from a NIST Perspective

Author(s)
John F. Banghart, Stephen D. Quinn, Kevin M. Stine
Security automation can harmonize the vast amounts of information technology (IT) data into coherent, comparable information streams that inform timely and...

Multiferroic Behaviour in the New Double-Perovskite Lu2MnCoO6

S. Yanez-Vilar, E. D. Mun, V. S. Zapf, B. G. Ueland, Jason S. Gardner, J. D. Thompson, J. Singleton, M. Sanchez-Andujar, J. Mira, N. Biskup, Rodriguez Senaris, C. D. Batista
We present a new member of the multiferroic oxides, Lu 2MnCoO 6, which we have investigated using X-ray diffraction, neutron diffraction, specific heat...

In Memoriam Professor Ralph L. Webb (1934-2011)

Author(s)
Mark A. Kedzierski, Richard Goldstien, Ephriam Sparrow, W.J. Minkowycz, Thomas Rudy, Nae-Hyun Kim, Wei Li, Thomas Adamek, Klaus Menze, Raj Manglik, Wieland-Werke AG, Sujoy K. Saha, Arthur Bergles

Determination of Moisture Content of Single-Wall Carbon Nanotubes

Author(s)
Rolf L. Zeisler, Rabia Oflaz, Ralph E. Sturgeon, Rick L. Paul, Brian E. Lang, Jeffrey A. Fagan, Joseph W. Lam, Anthony Windust, P Grinberg, Benoit Simard, Christopher T. Kingston
Several techniques were evaluated for the establishment of reliable water/moisture content of single-wall carbon nanotubes. Karl Fischer titration (KF) provides...

Impact of surface roughness on diffusion of confined fluids

Author(s)
William P. Krekelberg, Vincent K. Shen, Jeffrey R. Errington, Thomas M. Truskett
Using event-driven molecular dynamics simulations, we quantify how the self diffusivity of confined hard-sphere fluids depends on the nature of the confining...
