TRC For 75 years, the Thermodynamic Research Center has produced data resources to support scientific research and industrial process design. Located in Boulder, Colorado, TRC seeks to:
  • Collect and curate a comprehensive archive of experimental thermophysical and thermochemical property data
  • Serve as a comprehensive source of critically evaluated data for scientific and industrial applications
Under the auspices of the Materials Genome Initiative, TRC has extended its infrastructure to the field of material science - developing a framework for archiving experimental data from the scientific literature and disseminating those data to the scientific community.

Data Sources In order to guarantee consistently high-quality data, TRC collects information only from primary, publicly available sources. This approach allows for independent audit and avoids encumbrance from intellectual property issues. TRC does not consider simulated results to be primary data, as the quantitative reliability for a simulated result is generally unknown and is an area of active research.
Data Structure As part of its mission to provide data reliably to a broad range of interested parties, TRC maintains an IUPAC-standard XML format for dissemination of thermophysical and thermochemical property data, ThermoML. ThermoML is presently undergoing an approval process with the International Union of Pure and Applied Chemistry to extend support to metal-based systems. This format allows for consistent data representation, spanning industrial and academic needs with one data structure.
For details about ThermoML, see http://trc.nist.gov/ThermoML.html
Dynamic Data Evaluation For the past 20 years, TRC has been a pioneer in developing integrated systems for dynamic propagation of new experimental measurements and property estimation techniques into its critically evaluated recommendations. Exploring effective and efficient methodologies for data collection, curation and evaluation is one of the main focus areas and strengths of the Thermodynamic Research Center.
