Two caprock and cover collapse sinkholes, Wink Sinks #1 and #2, in Winkler County, Texas, collapsed in 1980 and 2002, respectively. They are located in a region underlain by the Salado Formation on the eastern edge of the Delaware Basin. The sinkhole

Electronic properties of polystyrene-acrylonitrile (PSA) films, implanted with 20–175-keV nitrogen to a dose range of 5 × 1013–5 × 1016 ions/cm2, were studied. Electrical conductivity of the films increases more than 17 orders of magnitude with

Ion beams modify the surface region of polymers by creating a number of carbon structures, whose basic properties differ greatly from the bulk polymer. These carbon structures may be stable or metastable depending on the conditions of implantation. T

In order to maximize the responsivity of a thermal detector, the detector is often fabricated on a thin membrane which is suspended over a substrate. Maximizing responsivity requires minimizing the thermal conductance and heat capacity while keeping

Ion beam implantation of polymers has been shown to modify electrical and mechanical properties near the surface of the material. A complete understanding of the mechanism of modification and type of microstructure remaining as a result of this proce

The mechanical and electronic properties of ion implanted polymers have been determined to be a function of ion dose, energy and beam current. In previous studies the implant layer was assumed to be isotropic. In an earlier report we speculated that

Subsidence from sinkhole collapse is a common occurrence in areas underlain by water-soluble rocks such as carbonate and evaporite rocks, typical of karst terrain. Almost all 50 States within the United States (excluding Delaware and Rhode Island) ha
