Soil-Structure Interaction for Building Structures

September 13, 2012
Author(s)
Jonathan Stewart, C.B. Crouse, Tara C. Hutchinson, Bret Lizundia, Farzad Naeim, Farhang Ostadan
The purpose of this project was to develop consensus guidance for implementing soil-structure interaction in response history analyses, and to identify areas of further research that were needed. The starting point for this work was decades of available

Quantum state preparation and control of single molecular ions

February 14, 2012
Author(s)
Dietrich G. Leibfried
Preparing molecules at rest and in a highly pure electronic, rotational and vibrational quantum state is a long standing dream in chemistry and physics, so far only achieved for a select set of molecules in experimental setups dedicated to that species

Asymptotically Optimal Confidences for Rejecting Local Realism

December 22, 2011
Author(s)
Yanbao Zhang, Scott Glancy, Emanuel Knill
Reliable experimental demonstrations of violations of local realism are highly desirable for fundamental tests of Quantum Mechanics. Such violations can be quantified in terms of a confidence for rejecting local realism. We propose a method for computing

Review of Current Progress in Nanometrology with Helium Ions

September 19, 2011
Author(s)
Michael T. Postek, Andras Vladar, Bin Ming, Charles Archie
Scanning electron microscopy has been employed as an imaging and measurement tool for more than 50 years and it continues as a primary tool in many research and manufacturing facilities across the world. A new challenger to this work is the helium ion

p-Wave Cold Collisions in an Optical Lattice Clock

September 2, 2011
Author(s)
Nathan D. Lemke, Andrew D. Ludlow, J. von Stecher, Jeffrey A. Sherman, A.M. Rey, Christopher W. Oates
State-of-the-art optical clocks with neutral atoms employ an optical lattice to tightly confine the atoms, enabling high-resolution spectroscopy and the potential for high-accuracy timekeeping. Interrogating many atoms simultaneously facilitates high

Revealing the Interphase in Polymer Nanocomposites

March 16, 2011
Author(s)
Mauro Zammarano, Paul H. Maupin, Li Piin Sung, Jeffrey W. Gilman, Douglas M. Fox
Morphological characterization of polymer nanocomposites is a fundamental challenge that is complicated by multiple length scales. Here, we report a technique for high-throughput monitoring of interphase and dispersion in polymer nanocomposites based on

The Thermodynamic Properties of Propane: From p-r-T to the Equation of State

September 14, 2010
Author(s)
Mark O. McLinden, Eric W. Lemmon
The p-ρ-T behavior of high-purity (99.999%) propane was measured from 265 K to 500 K with pressures to 36 Mpa using a two-sinker densimeter. The measurements extend from low-density vapor to compressed liquid states, and the near-critical region was

Metrology for the Electrical Characterization of Semiconductor Nanowires

November 1, 2008
Author(s)
Curt A. Richter, Hao Xiong, Xiaoxiao Zhu, Wenyong Wang, Vincent M. Stanford, Woong-Ki Hong, Takhee Lee, D. E. Ioannou, Qiliang Li
Nanoelectronic devices based upon self-assembled semiconductor nanowires are excellent research tools for investigating the behavior of structures with sub-lithographic features as well as a promising basis for future information processing technologies

Uncertainties in Scaling Factors for ab Initio Vibrational Frequencies

September 1, 2005
Author(s)
Karl K. Irikura, Russell D. Johnson III, Raghu N. Kacker
Vibrational frequencies determined from ab initio calculations are often scaled by empirical factors. An empirical scaling factor partially compensates for the errors arising from vibrational anharmonicity and incomplete treatment of electron correlation

Boundary Lubricated Wear

July 15, 2005
Author(s)
Stephen M. Hsu, R G. Munro, M C. Shen, Richard S. Gates
This chapter reviews the fundamental nature of wear under lubricated conditions and presents a comprehensive view of our current understanding of the wear processes under boundary lubrication conditions. Wear under lubricated conditions can be classified

Water Distribution Within Immersed Polymer Films

February 1, 2005
Author(s)
B D. Vogt, Christopher Soles, Vivek Prabhu, Sushil K. Satija, Eric K. Lin, Wen-Li Wu
The emergence of immersion lithography as a potential alternative for the extension of current lithography tools will require a fundamental understanding of the interactions between the photoresist and the immersion liquid such as water. The water
