Measurements of density, speed of sound, and viscosity have been carried out on liquid standard reference materials for biofuels as a function of temperature at ambient pressure. The samples included anhydrous and hydrated bioethanol and two biodiesels
As the availability of petroleum based liquid fuels is becoming increasingly problematic, alternative renewable biofuels attract growing R&D and industry interest. The focus is to produce fuels with desired properties in both technically and economically

A new data model for storage of experimental thermophysical and thermochemical property data was developed and implemented for NIST/TRC SOURCE data archival system. Substantial improvements in data quality as well as system usability and extendability are
A thermodynamic property formulation for dimethyl carbonate has been developed with the use of available experimental thermodynamic property data. The equation of state was developed with multi-property fitting methods involving single-phase pressure
Multistage pulse tube cryocoolers require separate phase shifters for each stage. For sufficiently high frequency and acoustic power, the inertance tube is commonly used for such phase shifting. For Stirling-type, multistage pulse tube cryocoolers the warm

Infrared spectra of spiropentane (C5H8) have been recorded at a resolution (0.002 cm-1) sufficient to resolve for the first time individual rovibrational lines. This initial report presents the ground state constants for this molecule determined from the
New experimental data on the thermal conductivity of 2,3,3,3-Tetrafluoroprop-1-ene (R1234yf) and trans-1,3,3,3-tetrafluoropropene (R1234ze) are reported that allow the development of wide-range correlations. These new experimental data, covering a
