ThermoData Engine (TDE) is the first full-scale software implementation of the dynamic data evaluation concept, as reported recently in this journal. In the present paper, we describe the development of a World Wide Web-based interface to TDE evaluations
Biodiesel fuel is an alternative fuel that can be derived from a number of renewable feedstocks including plant and vegetable oils, algae, animal fats, waste oils, etc. The fatty acid methyl ester (FAME) profile, and thus the resultant properties, of the
This presentation describes the current state of knowledge of the thermodynamic properties of pure carbon dioxide and of CO2-rich mixtures. It includes a description of NIST's REFPROP software and analysis of the dew point for CO2-H2O mixtures.

Densities of the missile fuel JP-10 were measured with two vibrating-tube densimeters. The combined range of the data is from 270 K to 470 K with pressures to 30 MPa. The speed of sound in the fuel was measured with a propagation time method at ambient

The NIST ThermoData Engine (TDE) is a large electronic database containing experimental data with detailed descriptions of relevant metadata and uncertainties that incorporates expert- system software to automatically generate dynamically evaluated data
As pointed out by the recent National Academy of Sciences report on forensic sciences, the study of fire patterns and debris in arson fires is in need of additional study and standardization. Part of the current difficulty is in determining the appropriate
The distillation curve is the only practical measurement used to characterize the vapor/liquid equilibrium (volatility) of a complex mixture. In earlier work, we described an improved method and apparatus for distillation curve measurement at atmospheric
The purpose of this work was to determine vapor pressures for saturated biodiesel esters at the low-temperature end of their liquid range. A "concatenated" gas saturation apparatus capable of simultaneous measurements on 18 samples was used for

This article describes an investigation of the transient behavior of a small (2.0 W at 85 K) Pulse Tube cryocooler operating at 120 Hz with an average pressure of 3.5 MPa, capable of relatively fast cool-down to about 60 K. In a series of experiments, the
The thermal stability of the kerosene-based rocket propellant RP-2 with varying concentrations of the stabilizing additive 1,2,3,4-tetrahydroquinoline (THQ) was investigated. The mixtures studied were RP-2 + 0.1 % THQ, RP-2 + 0.5 % THQ, RP-2 + 1 % THQ, and
