Multi-Scale Investigation of the Performance of Limestone in Concrete

Author(s)
Dale P. Bentz, Ahmad Ardani, Tim Barrett, Scott Z. Jones, Didier Lootens, Max A. Peltz, Taijiro Sato, Paul E. Stutzman, Jussara Tanesi, Jason Weiss
Limestone (calcium carbonate) has long been a critical component of concrete, whether as the primary raw material for cement production, a fine powder added to

New Methods for Measurement of Neutron Detector Efficiency up to 20 MeV

Author(s)
Fred B. Bateman, Allan D. Carlson, N. A. Kornilov, S M. Grimes, T N. Massey, C E. Brient, D E. Carter, J E. O'Donnell, R. C. Haight, N Boukharouba
A new approach to neutron detector effciency has been taken. A neutron detector has been calibrated with a Cf-252 source at low energy. The calibration was

Flat lens criterion by small-angle phase

Author(s)
Peter Ott, Mohammed H. Al Shakhs, Henri Lezec, Kenneth J. Chau
It is sometimes possible to image using a flat lens consisting of planar, uniform media. There is conceptual division between theoretical flat lens proposals

Martin J. Burns, John A. Teeter, David A. Wollman
Our goal in the Green Button Initiative is to provide electricity customers with easy access to their energy usage data in a consumer-friendly and computer

Quantum engineering of atomic phase shifts in optical clocks

Author(s)
Andrew D. Ludlow, T Zanon-willette, S. Almonacil, E. de Clercq, Ennio Arimondo
Quantum engineering of time-separated Raman laser pulses in three-level systems is presented to produce an ultra-narrow, optical-clock transition free from

Measurement of the Electrostatic Edge Effect in Wurtzite GaN Nanowires

Author(s)
Alex Henning, Benjamin Klein, Kristine A. Bertness, Paul T. Blanchard, Norman Sanford, Yossi Rosenwaks
The electrostatic effect of the hexagonal corner on the electronic structure in wurtzite GaN nanowires (NWs) was directly measured using Kelvin probe force
