Limits of Storage in Magnetic Materials

December 31, 2004
Author(s)
Thomas J. Silva
I summarize what is currently known about how thermal effects limit the storage capacity of magnetic disk drives. The physics of thermal fluctuations in magnetic materials is treated in some detail, though the essential points are covered in a tutorial

Testing of Small-Sized Specimens

September 26, 2014
Author(s)
Enrico Lucon
An extensive review of the current state-of-the-art of small specimen test technology (SSTT) has been presented, covering a number of experimental techniques aimed at characterizing the mechanical properties of materials and components through the use of

The NIST Handbook of Mathematical Functions

May 12, 2010
Author(s)
Frank W. Olver, Daniel W. Lozier, Ronald Boisvert, Charles W. Clark
The NIST Handbook of Mathematical Functions supplies validated reference information in 36 chapters on a wide selection of important mathematical functions, covering the properties necessary for their use in scientific applications, together with general

NIST Metric Cube

Author(s)
J B. McCracken
Paper cut-out cube, 10 cm on each side listing metric conversion information on each face covering units of length, mass or weight, area or surface, energy, volume and temperature. The bottom face lists common metric prefixes.

The relation between vegetation and storm-water runoff in Portland, Oregon

September 1, 2016
Author(s)
Geoffrey Donovan, David Butry
Past research has examined the effect of urban trees on storm-water runoff using hydrological models or small-scale experiments. However, there has been no statistical analysis of the influence of trees on runoff in an intact urban watershed. We address

Molecular Orientation of Single and Two-Armed Monodendron Semifluorinated Chains on Soft and Hard Surfaces Studied Using NEXAFS

August 1, 2000
Author(s)
Jan Genzer, E Sivaniah, E K. Kramer, J G. Wang, M Xiang, K Char, Christopher K. Ober, Robert A. Bubeck, Daniel A. Fischer, M Graupe, R Colorado, O E. Shmakova, T R. Lee
Near-edge absorption fine structure (NEXAFS) measurements are used to probe the molecular orientation of semifluorinated (SF) mesogens, -(CH 2)x(CF 2)yF, which are attached to I) the isoprene backbone of polyisoprene or a styrene-isoprene diblock copolymer

NIST Metric Pyramid

April 1, 2002
Author(s)
J B. McCracken
Paper cut-out pyramid, 10 cm x 10 cm x 10 cm, listing metric conversion information on each face covering units of length, mass or weight, area or surface, energy, volume and temperature. The bottom face lists metric symbols.

Odyssey Text Independent Evaluation Data

January 1, 2001
Author(s)
Mark A. Przybocki, Alvin F. Martin
We discuss the text-independent data supplied for the 2001: A Speaker Odyssey evaluation track. We cover the data creation and selection process, and we present results restricted to the Odyssey test set for participating systems in the 2000 NIST Speaker

CCQM_Retrospectoscope Reference Manual: A detailed reference to the CCQM_Retrospectoscope, a suite of graphical tools for the meta-analysis of measurement results from CCQM studies

December 12, 2024
Author(s)
David L. Duewer, Christina Cecelski, Michael Nelson
This document is a detailed reference manual for the 1-September-2024 version of the CCQM_Retrospectoscope system. The CCQM_Retrospectoscope combines a nominally complete database of results from Consultative Committee for the Amount of Substance

Microfabricated strontium atomic vapor cells

January 5, 2023
Author(s)
Jacob Pate, John Kitching, Matthew Hummon
We demonstrate strontium (Sr) atomic vapor cells having a total external volume of 0.63 cm3 that can operate above 300 °C for times exceeding 380 h. The cells are fabricated using micromachined silicon frames anodically bonded to glass windows that have a

Compliance-Free Pulse Forming of Filamentary RRAM

September 30, 2016
Author(s)
Pragya Shrestha, David M. Nminibapiel, Jihong Kim, Helmut Baumgart, Kin (Charles) Cheung, Jason Campbell
… tailoring the forming energy, we show remarkable endurance window control. …

Low Helium Permeation Cells for Atomic Microsystems Technology

June 15, 2016
Author(s)
Argyrios Dellis, Shah Vishal, Elizabeth A. Donley, Svenja A. Knappe, John E. Kitching
The miniaturization of instruments and sensors based on laser-cooled atoms is hindered by the large pumps needed to maintain the vacuum requirements. A significant source of vacuum contamination is the permeation of gases through the walls of the chamber
