Monists about material constitution typically argue that when Statue is materially constituted by Clay, Statue is just Clay. Pluralists about material constitution deny that constitution is identity: Statue is not just Clay. When Clay materially constitutes Statue, Clay is not identical to Statue. I discuss three familiar puzzles involving grounding, overdetermination and conceptual issues, and...

-Multivariate statistical analyses of geochemical, mineralogical, and cation-exchange capacity (CEC) data from a Venezuelan oil well were used to construct a model which relates elemental concentrations to mineral abundances. An r-mode factor analysis showed that most of the variance could be accounted for by four independent factors and that these factors were related to individual mineral com...

This study investigates the nano to core-scale geomechanical properties of a maturity series organic-rich, calcareous shales buried 100°C–180°C, with focus on: (a) mechanical organic matter; (b) elastic response and anisotropy shale composite at micro core scale; (c) creep response. Atomic force microscopy was used target kerogen nanoscale resolution, it found that stiffness increased thermal f...

Transport properties in shales were investigated using experimental and computersimulation methods. First, an experimental method based on a transient pressuredecay technique was further developed and used instead of classical Darcy core-flood methods. This has allowed measurement of the permeability of tight shale samples on much shorter time scales than by conventional methods. Second, molecu...

Introduction: The remediation of nuclear contamination in soils and sediments at the Savannah River Site, SC (SRS) is an ongoing government project with implications for the health of ecosystems near the site. In addition to environmental protection, the safety of the food and drinking water produced in the region is also at risk for impurity. In previous studies, hydroxy-interlayered vermiculi...

We developed ceramic core-shell materials based on abundant halloysite clay nanotubes with enhanced heavy metal ions loading through Schiff base binding. These clay tubes are formed by rolling alumosilicate sheets and have diameter of c.50 nm, a lumen of 15 nm and length ~1 μm. This allowed for synthesis of metal nanoparticles at the selected position: (1) on the outer surface seeding 3-5 nm me...
