Finite Element Modeling of Materials with Complex Microstructure (OOF)

Data provided by  National Institute of Standards and Technology

OOF is software for analyzing the properties of materials with complex microstructures. Starting with a micrograph of a real or simulated material, OOF allows users to assign material properties to features of the microstructure, to construct a finite element mesh from the microstructure geometry, and to perform virtual experiments on the microstructure.

NIST Chem-BLAST Gateway for PDB

Data provided by  National Institute of Standards and Technology

Chemical Block Layered Alignment of Substructure or Chem-BLAST uses a method for finding chemical compounds within a large collection. In this method, all chemical compounds are annotated in terms of standard chemical structural fragments. These fragments are then organized into a data tree based on their chemical substructures. Search engines have been developed to use this data tree. These search engines use the Chem-BLAST technique to search on the fragments and look for their chemical structural neighbors.

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 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.
