This study presents the effects of equations of state (EOSs) on methane adsorption capacity, sorption hysteresis and initial gas reserves of a medium volatile bituminous coal. The sorption experiments were performed, at temperatures of 25... more
Aquifer sediments collected via split-spoon sampling in two new groundwater wells in the 200-UP-1 operable unit at the Hanford Site were characterized and showed typical Ringold Unit E Formation properties dominated by gravel and sand.... more
ABSTRACT A number of previous studies have reported the existence of a minimum in phosphate solubility between pH 5.5 and 7 in non-calcareous soils. Different hypotheses have been forwarded to explain this phenomenon. In this study, ten... more
Elevated arsenic and selenium concentrations in water cause health problems to both humans and wildlife. Natural and anthropogenic activities have caused contamination of these elements in waters worldwide, making the development of... more

This paper describes quantitation of biodegradation kinetics in soil slurry and compacted soil systems using polycyclic aromatic hydrocarbons (PAHs) as the test contaminants. The experimental protocol, elaborated in this paper, results in... more
ABSTRACT a b s t r a c t The influence of contact time, temperature and particle size on lead sorption by the natural and Fe(III)-modified zeolites was investigated. Characterization of the natural and Fe(III)-modified zeolite before and... more
Lawrence Livermore National Laboratory (LLNL) has developed a mass spectrometer-based system that measures organic surface residues in situ. This system, called the Contamination Analysis Unit (CAU), can detect and quantify a variety of... more
The objective of this study was to test the availability of the boron from doped oxides to rape (Brassica napus L.), and the effect of the boron doped oxides on soil acidosis. The soil was treated with goethite, manganite and their... more
ABSTRACT This work reports experimental data on the desorption of pure propane and n‐butane from refined soybean oil at low pressures. The desorption parameters investigated were the overall solvent (normally gaseous at ambient... more
ABSTRACT Surface modification of biomaterials has been adopted over the years to improve their biocompatibility. In this study, aiming to promote hydrophilicity and to introduce natural recognition sites onto poly(L-lactic acid) (PLLA)... more
