Fatigue Crack Growth Modeling of Pipeline Steels in High Pressure Gaseous Hydrogen

October 21, 2013
Author(s)
Robert L. Amaro, Elizabeth S. Drexler, Andrew J. Slifka
Hydrogen will likely play a key role in a future clean energy economy. However, fundamental understanding of the deleterious effects of hydrogen on the fatigue and fracture properties of pipeline steels is lacking. Furthermore, engineering tools for design

Surface science for improved ion traps

September 30, 2013
Author(s)
David P. Pappas, Dustin Hite, Andrew C. Wilson, David T. Allcock, David J. Wineland, Dietrich Leibfried, Yves Colombe
Trapped ions are sensitive to electric-field noise from trap-electrode surfaces. This noise has been an obstacle to progress in trapped-ion quantum information processing (QIP) experiments for more than a decade. It causes motional heating of the ions, and

Effectively Control Negative Thermal Expansion of Single-phase Ferroelecrics of PbTiO 3 -(Bi,La)FeO 3 over a Giant Range

August 16, 2013
Author(s)
Jun Chen, Fangfang Wang, Qingzhen Huang, Lei Hu, Xiping Song, Jinxia Deng, Ranbo Yu, Xianran Xing
Control of negative thermal expansion is a fundamentally interesting topic in the negative thermal expansion materials in order for the future applications. However, it is a challenge to control the negative thermal expansion in individual pure materials

Adhesion Society Meeting Proceedings

March 3, 2013
Author(s)
Rebecca Ploeger, Aaron Forster, Donald Hunston, Etienne de la Rie, Christopher McGlinchey
Consolidating adhesives have been used throughout the centuries for the conservation of painted cultural objects- such as paintings and polychrome sculpture- and if it were not for these adhesives, many objects may not have survived to the present day

The New Golden Age of Algorithms and Data Structures

October 29, 2012
Author(s)
Paul E. Black
Before 1976 Communications of the ACM printed (and numbered!) new algorithms every issue. Quicksort was invented in 1960, Boyer-Moore string search in 1977, and combsort in 1980. I haven't seen a new, general sorting algorithm in over a decade. The latest

CHARACTERIZING SUSTAINABILITY FOR MANUFACTURING PERFORMANCE ASSESSMENT

August 17, 2012
Author(s)
Mahesh Mani, Jatinder Madan, Jae H. Lee, Kevin W. Lyons, Satyandra K. Gupta
Manufacturing industries lack the measurement science and the needed information base to measure and effectively compare performances of manufacturing processes, resources and associated services with respect to sustainability. The current use of ad-hoc

Quantification of ligand packing density on gold nanoparticles using ICP-OES

February 18, 2012
Author(s)
Sherrie R. Elzey, De-Hao D. Tsai, Savelas A. Rabb, Lee L. Yu, Michael R. Winchester, Vincent A. Hackley
In this study, a prototypical thiolated organic ligand, 3-mercaptopropionic acid (MPA), was conjugated on gold nanoparticles (AuNPs), and packing density was measured on an ensemble-averaged basis using inductively coupled plasma optical emission

Spin transport in memristive devices

January 26, 2012
Author(s)
Hyuk-Jae Jang, Oleg A. Kirillov, Oana Jurchescu, Curt A. Richter
We report on electron spin transport through electrochemically precipitated copper filaments formed in TaOX memristive devices consisting of Co(60nm)/TaOX(16nm)/Cu(5nm)/Py(60nm) with crossbar-type electrode geometry.The devices show memristive behavior

Managing the Configuration of Information Systems with a Focus on Security

September 26, 2011
Author(s)
Shirley M. Radack
This bulletin summarizes the information presented in NIST Special Publication (SP) 800-128, Guide to Security-Focused Configuration Management of Information Systems. The publication was written by Arnold Johnson, Kelley Dempsey, and Ron Ross of NIST, and

From Electrons to Infrastructure: Engineering Concrete From The Bottom Up

April 6, 2011
Author(s)
Hamlin M. Jennings, Jeffrey W. Bullard
We argue that only an approach rooted in fundamental, mechanistic models of concrete materials offers a viable path for handling the enormous number of new variables that are being introduced as new materials are added to the design space, and as new

Multimodal, Nanoscale, Hyperspectral Imaging Demonstrated on Heterostructures of Quantum Dots and DNA-Wrapped Single-Wall Carbon Nanotubes

October 21, 2009
Author(s)
Hyeong G. Kang, Matthew L. Clarke, Jianyong Tang, John T. Woodward IV, Shin G. Chou, Zhenping Zhou, Angela R. Hight Walker, Tinh Nguyen, Jeeseong Hwang
A multimodality imaging technique integrating atomic force, polarized Raman, and fluorescence lifetime microscopy and a 2D autocorrelation image analysis is applied to study the properties of a mesoscopic heterostucture of nanoscale materials. This

Scaling Factors and Uncertainties for ab Initio Anharmonic Vibrational Frequencies

August 21, 2009
Author(s)
Russell D. Johnson III, Karl K. Irikura, Raghu N. Kacker, Ruediger Kessel
To predict the vibrational spectra of molecules, ab initio calculations are often used to compute harmonic frequencies, which are usually scaled by empirical factors as an approximate correction for errors in the force constants and for anharmonic effects

Climbing the Vibrational Ladder to Probe the OH Stretch of HNO 3 on Silica

October 16, 2008
Author(s)
A C. Pipino, Marcin Michalski
The first and second OH-stretching overtones of HNO3 adsorbed on atomically smooth amorphous SiO2 have been probed by evanescent wave cavity ring-down spectroscopy (EW-CRDS) using a broadband high-finesse total-internal-reflection-ring resonator. In

Robust Estimation of Effect Sizes Using Influence Functions

October 16, 2008
Author(s)
James H. Yen
The estimation of effect sizes is crucial part of meta-analysis. This papers uses influence functions as a fundamental tool in the analysis of estimates of effect size. The generalization to several variables of the influence function provides heuristic

Recent atomic clock comparisions at NIST

Newbury, Tom Parker, Till P. Rosenband, Jason Stalnaker, William C. Swann, David J. Wineland, James C. Bergquist
The record of atomic clock frequency comparisons at NIST over the past half-decade provides one of the tightest constraints of any present-day, temporal variations of the fundamental constants. Notably, the 6-year record of increasingly precise
