The MINEX II trials have been conducted to evaluate the accuracy and speed of MATCH-ON-CARD verification algorithms. These run on ISO/IEC 7816 smartcards. They compare reference and verification data conformant to the ISO/IEC 19794-2 COMPACT CARD
We derive path-integral expressions for the second and third virial coefficients of monatomic quantum gases. Unlike previous work that considered only Boltzmann statistics, we include exchange effects (Bose-Einstein or Fermi-Dirac statistics). We use state
When an emergency occurs, it is not always sufficient to simply initiate alarm bells. Individuals may not know what the alarm bell means and, in turn, respond inappropriately to its sound. Many buildings have installed mass notification or emergency
We have recently introduced several important improvements in the measurement of distillation curves for complex fluids. The modifications include a composition explicit data channel for each distillate fraction and temperature measurements that are true

The electrodeposition of a series of metastable Pt-Pb alloys and intermetallic phases as well as elemental Pt is demonstrated using an acid electrolyte comprised of 0.05 mol/L Pb(ClO_4)_2 and/or 0.001 mol/L K_2PtCl_4. Pt-Pb films were deposited at various

Electrocatalytic formic acid oxidation is examined on electrodeposited Pt_100-x}Pb_x} thin films grown on textured Au(111). Metastable fcc Pb_100-x}Pt_x} (0

Persistent organic pollutants (POPs) are a recognized man-made threat to sea turtle populations, but the uncertainty surrounding exposure and sensitivity of sea turtles to contaminants is great and makes decision making difficult for conservation managers

This NIST standard reference web subscription database provides access to more than 50 thermophysical and thermochemical property data and their uncertainties, critically evaluated for 150 commonly-used pure chemical compounds. The majority of these data

This NIST standard reference web subscription database provides access to more than 50 thermophysical and thermochemical property data and their uncertainties, critically evaluated for more than 23,000 pure chemical compounds. The majority of these data
More than 100 years ago, Lord Kelvin observed that measurement is vital to deep knowledge and understanding in physical science. During the last few decades, researchers have made various attempts to develop measures and systems of measurement for computer

Ni superconformal filling of sub-micrometer trenches is demonstrated using a Watts bath containing an inhibitor 2-mercaptobenzimidazole (MBI). Hysteretic voltammetry marks the breakdown of the MBI-induced passive-state coincident with the onset of Ni
Test structures are critical tools for semiconductor manufacturers, allowing for understanding of the process and individual circuit elements that cannot be acquired from measurements of the circuits, which can have billions of transistors and other

Oxidative stress occurs when the generation of reactive oxygen species (ROS) exceeds the capacity of the cells endogenous systems to neutralize them. We analyzed the oxidative stress responses and cellular damage of the archaeon Halobacterium salinarum

A non-diffracting surface layer exists at any boundary of a crystal and can comprise a mass fraction of several percent in a finely divided solid. This has led to the long-standing issue of amorphous content in standards for quantitative phase analysis

This article reviews the history of egress design and code requirements in the United States, describes the current state-of-the-art in egress design and modeling, and offers a strawman research agenda for future egress research.
A personal view by the author of how, as a research engineer and manager, first in the private sector and now in government service, he witnessed the emergence of a compelling case for sustainable manufacturing and also gained several important insights
This study examines the energy consumption of automatic ice makers installed in domestic refrigerators. The purpose of this research is to determine a method of measuring the energy consumption of automatic ice makers that will generate a repeatable and

The formation of silver nanoparticles (AgNPs) via reduction of silver ions (Ag+) in the presence of humic acids (HAs) under various environmentally relevant conditions is described. HAs tested were from Suwannee River (SUW), and samples of three sediment
The Moore M48 coordinate measuring machine (CMM) has provided NIST with flexible measurement capabilities for many years. The machines state of the art performance was further improved following the move of the machine into the new Advanced Measurement
