Development of an automated millifluidic platform and data-analysis pipeline for rapid electrochemical corrosion measurements: a pH study on Zn-Ni

July 25, 2022
Author(s)
Howard Joress, Brian DeCost, Najlaa Hassan, Trevor Braun, Justin Gorham, Jason Hattrick-Simpers
We describe the development of a millifluidic based scanning droplet cell platform for rapid and automated corrosion. This system allows for measurement of corrosion properties (e.g., open circuit potential, corrosion current through Tafel and linear

An Ontological Modeling Platform

June 4, 2008
Author(s)
V.C. Liang, Conrad E. Bock, XuanFang Zha
The Ontological Modeling Platform described in this paper is a class library for extended ontological operations, to support extension of ontology languages, composition of interconnected elements, and high-level product modeling services, such as

Mode-selective acoustic spectroscopy of trigonal piezoelectric crystals

May 1, 2008
Author(s)
Ward L. Johnson, Carlos F. Martino, Sudook A. Kim, Paul R. Heyliger
A noncontacting electromagnetic-acoustic-resonance technique is presented for generating and detecting vibrational modes with prescribed symmetries in piezoelectric trigonal crystals with cylindrical geometry. This technique provides the experimental basis

2-D Imaging of Temperature in CF 4 Plasmas

April 1, 2005
Author(s)
Kristen L. Steffens, Mark A. Sobolewski
Two-dimensional maps of rotational temperature were determined in CF4 plasmas using planar laser-induced fluorescence of CF. Experiments were performed in a capacitively-coupled, parallel plate plasma reactor at pressures from 200mTorr (26.7Pa) to 800mTorr

The Boundary of X-Ray and Electron Tomography

January 3, 2005
Author(s)
Zachary H. Levine
Samples a few micrometers in total size offer a challenge to both x-ray and electron tomography. X-ray tomography originated imaging the human body with millimeter resolution, but the resolution has been reduced by over 7 orders of magnitude by the use of

Electrometrology and NIST -- New Directions

July 1, 2001
Author(s)
William E. Anderson
I gaze into a somewhat cloudy crystal ball to predict the directions of electrical metrology in the next fifteen years. The emphasis on standards based on fundamental constants of nature and on quantum-mechanical principles will move from the base units to

Concrete Rheology: Knowledge and Challenges?

September 13, 2006
Author(s)
Chiara F. Ferraris
The design of concrete with specified properties for an application is not a new science, but it has taken on a new meaning with the wide use of special concretes, such as self compacting concrete (SCC). General terms such as flow under its own weight and

MSEL FY 2001 Programs and Accomplishments: Metallurgy Division

September 1, 2001

C A. Handwerker, Robert J. Schaefer
This report describes major programs and accomplishments of the Metallurgy Division of the NIST Materials Science and Engineering Laboratory (MSEL) in FY2000.The mission of the NIST Metallurgy Division is to provide critical leadership in the development

Recent Advances in Fire-Structure Analysis

February 1, 2008
Author(s)
Dat Duthinh, Kevin B. McGrattan, Abed M. Khaskia
One of the recommendations of the National Construction Safety Team for the Federal Building and Fire Safety Investigation of the World Trade Center Disaster (NIST NCSTAR 1, 2005) is to enhance the capability of available computational software to predict

Vacuum-Gap Capacitors for Low-Loss Superconducting Resonant Circuits

June 16, 2009
Author(s)
Katarina Cicak, Michael S. Allman, Joshua Strong, Kevin Osborn, Raymond W. Simmonds
Low-loss microwave components are used in many superconducting resonant circuits from multiplexed readouts of low-temperature detector arrays to quantum bits. Two-level system (TLS) defects in amorphous dielectric materials cause excess energy loss. In an
