647-1 Thermodynamic Evaluations Using Web Protocols
Vladimir Diky, 303-497-4124, diky [at] boulder.nist.gov
A large amount of trusted thermodynamic and thermophysical data is available from the Internet. They are provided by scientific organizations motivated to share those data with the community. The Thermodynamics Research Center (TRC) at NIST is one of the providers of such databases [1]. However, TRC data analysis software such as ThermoData Engine (TDE) [2] works with local data sources such as local and network databases or data files. Data exchange using Web protocols would be a useful additional option for TDE. To implement it, appropriate functions should be developed in TDE, as well as Web interfaces and protocols for the dispaly and review of the various data sources. Web-based tool development would be a major component of this work. A successful candidate should have basic knowledge of thermodynamics and experience in Web development.

686-1 Calibrating Scales to Weigh Photons
Paul Williams, 303-497-3805, paul.williams [at] nist.gov
Light has momentum, and a laser’s power can be measured from the force of its light pushing on a mirror. We measure huge laser powers with simply a force balance and mirror. This measurement relies on the accuracy of the scale’s calibration for small forces (down to a few nanonewtons). We are building a robotic mass calibration system for this mass calibration of these balances for radiation pressure measurements.
