NIST/ASME Steam Properties Database - SRD 10

Data provided by  National Institute of Standards and Technology

The NIST/ASME Steam Properties Database is based upon the International Association for the Properties of Water and Steam (IAPWS) 1995 formulation for general and scientific use for the thermodynamic properties of water, this updated version provides water properties from the international standards over a wide range of conditions. Version 3.0 incorporates new IAPWS standards adopted in 2008 for the viscosity and for the melting and sublimation curves and in 2011 for the thermal conductivity.

NIST-JANAF Thermochemical Tables - SRD 13

Data provided by  National Institute of Standards and Technology

The Fourth Edition to the NIST-JANAF Thermochemical Tables has been assembled under the sponsorship of the Standard Reference Data Program at the National Institute of Standards and Technology. It contains tables of recommended temperature-dependent values for the standard enthalpy of formation, Gibbs (free) energy of formation, the logarithm of the equilibrium constant of formation, the heat capacity, entropy, enthalpy, and Gibbs energy function for 48 elements and many of their compounds.

NIST Synthetic Polymer MALDI Methods Database

Data provided by  National Institute of Standards and Technology

This resource consists of methods for matrix-assisted laser desorption ionization (MALDI) mass spectrometry on a wide variety of synthetic polymers. The methods are taken from the peer-review scientific literature. The database covers the period from 1988, the year of Tanaka's first paper on the subject, through 2011. Each recipe comes with a literature citation and associated digital object identifier (DOI) when available. The database currently contains entries for over 1250 polymer/matrix combinations.

NIST ThermoPlan - Experimental Planning and Coverage Evaluation Aid for Thermophysical Property Measurements - SRD 167

Data provided by  National Institute of Standards and Technology

This web application provides free and open access for the broader research community to the experimental planning utilities that are incorporated into ThermoData Engine (TDE) [J. Chem. Inf. Model. 2005, 45, 816-838]. TDE provides recommendations for the relative merit of a proposed measurement via assessment of the existing body of knowledge, including availability of experimental thermophysical property data, variable ranges studied, associated uncertainties, state of prediction methods, and parameters for deployment of prediction methods.

BTOP Map

Data provided by  National Telecommunications and Information Administration

The BTOP Map allows the public to visualize the impact of more than $4 billion in broadband investments being made through the American Recovery and Reinvestment Act (Recovery Act). Organizations awarded grants through the Broadband Technology Opportunities Program (BTOP) submit performance reports that summarize their project's progress in advancing broadband access and adoption across the country. These reports can be found on the BTOP website.

Aged Body Armor- Linking Theory to Practice by Predicting Ballistic Performance from Mechanical Properties

Data provided by  National Institute of Standards and Technology

We present correlations found between the tensile strengths of yarns extracted from armor and the V50 ballistic limit when significant degradation of the mechanical properties of the extracted yarns was observed. These studies provided the basis for a validation dataset from which we compare the experimentally measured V50 ballistic limit results to the theoretically predicted V50 results. This approach is promising for the development of a tool for fielded-armor-performance surveillance relying upon mechanical testing of armor coupon samples.

NIST Web Thermo Tables (WTT) - Professional Edition - SRD 203

Data provided by  National Institute of Standards and Technology

The Web Thermo Tables (WTT) are a collection of critically evaluated thermodynamic property data for pure compounds with a primary focus on organics. These data were generated through dynamic data analysis, as implemented in the NIST ThermoData Engine software package. Also included are some critically evaluated data from the historical TRC Thermodynamic Tables archive. The Professional Edition contains information on over 28,000 compounds.
