Interfacial area measurements for unsaturated flow through a porous medium
[1] Multiphase flow and contaminant transport in porous media are strongly influenced by the presence of fluid-fluid interfaces. Recent theoretical work based on conservation laws and the second lawExpand

Ferric-ferrous equilibria in natural silicate liquids at 1 bar
Ferric and ferrous iron concentrations have been measured in 57 silicate liquids equilibrated at temperatures (1,200°–1,330°C) above the liquidus and at oxygen fugacities close to those defined byExpand

Ultrasonic studies of silicate melts
The ultrasonic velocity and absorption of 32 silicate melts have been determined as a function of temperature (1175–1925 K) and frequency (3–12 MHz). The samples include the components SiO2, TiO2,Expand

Laser heated diamond cell system at the Advanced Photon Source for in situ x-ray measurements at high pressure and temperature
We describe a laser heated diamond anvil cell system at the GeoSoilEnviroCARS sector at the Advanced Photon Source. The system can be used for in situ x-ray measurements at simultaneously ultrahighExpand

Three-dimensional Microorganization of the Soil–Root–Microbe System
Soils contain the greatest reservoir of biodiversity on Earth, and the functionality of the soil ecosystem sustains the rest of the terrestrial biosphere. This functionality results from complexExpand

The COMPRES/GSECARS gas-loading system for diamond anvil cells at the Advanced Photon Source
We have designed and constructed a new system for loading gases at high pressure into diamond anvil cells at pressures up to 200 MPa. The gases are used either as quasi-hydrostatic pressure mediaExpand

Pore-scale characteristics of multiphase flow in porous media: A comparison of air–water and oil–water experiments
Abstract Studies of NAPL dissolution in porous media have demonstrated that measurement of saturation alone is insufficient to describe the rate of dissolution. Quantification of the NAPL–waterExpand
