Materials compatibility and lubricants research on CFC-refrigerant substitutes: Thermophysical properties

Description: Numerous fluids have been identified as promising alternative refrigerants, but much of the information needed to predict their behavior as pure fluids and as components in mixtures does not exist. In particular, reliable thermophysical properties data and models are needed to predict the performance of the new refrigerants in heating and cooling equipment, and to design and optimize equipment to be reliable and energy efficient. The objective of this project is to provide highly accurate, sele… more

Structure and dynamics in low-dimensional guest-host systems

Description: New synthetic materials continue to be discovered at a rapid rate. Many of these can be broadly described as guest-host systems, in the sense that a range of compositions is accessible by selectively inserting heteroatoms or molecules into the interstitial sites in an otherwise pure starting material. The premier examples are layer intercalates (graphite, transition metal di- and trichalocogenides, silicate clays) and doped polymers (notably polyacetylene). With a somewhat broader definition of… more

Enhanced coal hydrogasification via oxidative pretreatment

Description: The gasification of coal char by hydrogen is much slower than in steam or carbon dioxide; moreover, hydrogasification rate in pure hydrogen decreases sharply with conversion for most carbons. To overcome this kinetic behavior, the oxidation of the char prior to and during hydrogasification has been investigated as a means of enhancing hydro gasification rate. Kinetic rate studies under well-characterized conditions have been complemented by careful surface analyses to characterize oxygen on the… more

Stress-Relief Displacements Induced by Drilling--Applications to Holographic Measurements of in Situ Stress

Description: The holographic stressmeter is an instrument which has been developed at Caltech to allow determination of the complete stress tensor from in situ borehole measurements. The stressmeter uses double-exposure holographic interferometry to record the displacements induced by the drilling of a small sidehole into the borehole wall. The local stresses, which are the result of the far-field stresses, concentrated at the borehole, cause deformation of the surface of the borehole wall in the vicinity o… more
