Energy-Level Alignment and Work Function Shifts for Thiol-Bound Monolayers of Conjugated Molecules Self-Assembled on Ag, Cu, Au, and Pt

July 1, 2007
Author(s)
Christopher D. Zangmeister, Laura B. Picraux, Roger D. van Zee, Yuxing Yao, J M. Tour
Photoemission spectra have been used to determine the energy-level alignment and work function of monolayers of 4,4'-bis-(phenylethynyl)benzenethiol, 2 naphthalene thiol, and 3-(naphthalen-2-yl)propane-1-thiol self-assembled on Ag, Cu, Au, and Pt. For each

… of whether the wind load factors specified in the ASCE 7-95 Standard for hurricane-prone regions on the one hand and … hurricane wind loads inducing the design strength of about 500 y if epistemic uncertainties are neglected, and significantly lower than 500 years otherwise. …

GPS Carrier-Phase Time Transfer Boundary Discontinuity Investigation

November 26, 2012
Author(s)
Jian Yao, Judah Levine
We report on a study of the carrier-phase time transfer boundary discontinuity by the use of the precise point positioning (PPP) technique. Carrier-phase time transfer is first compared with two-way satellite time and frequency transfer (TWSTFT) between

Author(s)
Simon P. Frechette
A Model-Based Enterprise (MBE) is an organization that applies modeling and simulation technologies to integrate and manage its technical and business processes related to production and product lifecycle support. By using product and process models to

Modern Wavelength Standards in the Ultraviolet and Vacuum Ultraviolet

July 1, 1999
Author(s)
Joseph Reader, Craig J. Sansonetti
In recent work at the National Institute of Standards and Technology the Atomic Spectroscopy Group has characterized several sources of wavelength standards useful for remote sensing applications. At low resolution, mercury pencil-type lamps are convenient

Cyanate Ester Clay Nanocomposites: Synthesis and Flammability Studies

May 23, 1999
Author(s)
Jeffrey W. Gilman, Richard H. Harris Jr., Douglas Hunter
New goals outlined by the U. S. Federal Aviation Administration (FAA) Advanced Fire-Safe Aircraft Materials Research Program enumerate an order-of-magnitude improvement in aircraft cabin-material fire safety. In the pursuit of improved approaches to the
