Sharpless, Joanne M. Holden, K W. Andrews, Janet M. Roseland, Cuiwei Zhao, Amy Schweitzer, J Harnly, W Wolf, C R. Perry
Although an estimated 50% of US adults consume dietary supplements, analytically substantiated data on their bioactive constituents are sparse. Several programs...

Origin of Adhesion in Humid Air

Author(s)
Doo-In Kim, Jaroslaw Grobelny, Pradeep N. Namboodiri, Robert F. Cook
The origin of adhesion at nanoscale contacts in humid air is investigated by pull-off force measurements using atomic force microscopes in controlled...

Atoms in a Radio-Frequency-Dressed Optical Lattice

Author(s)
Ian B. Spielman, James V. Porto, William D. Phillips, Ben Brown, Patricia Lee, Nathan Lundblad
We load cold atoms into an optical lattice dramatically reshaped by radio-frequency coupling of statedependent lattice potentials. This radio-frequency dressing...

Shear Thinning Near the Critical Point of Xenon

Author(s)
Robert F. Berg, Michael R. Moldover, M Yao, G A. Zimmerli
We measured shear thinning, a viscosity decrease ordinarily associated with complex liquids, near the critical point of xenon. The data span the range of...

Thermal Voltage Converter Calibrations Using a Quantum AC Standard

Author(s)
Thomas E. Lipe Jr., Joseph R. Kinard Jr., Yi-hua D. Tang, Samuel Benz, Charles J. Burroughs, Paul Dresselhaus
We report on the first-ever use of a quantum ac source to calibrate a thermal transfer standard as part of the NIST calibration service for such devices, with...

Direct Experimental Observation of the Goos Hanchen Shift

Author(s)
H G. Schwefel, W Kohler, Z Lu, Jingyun Fan, L Wang
We report a precise direct measurement of the Goos-Hanchen (GH) shift after one reflection off a dielectric interface coated with periodic metal stripes. The...

A z-component magneto-resistive sensor

Author(s)
Fabio C. da Silva, Sean Halloran, Lu Yuan, David P. Pappas
A thin-film sensor is described that measures the component of the magnetic field perpendicular to the plane of the substrate (also called the z-component field...
