Abstract: In an embodiment, a polycrystalline diamond compacts (“PDC”) includes a substrate and a polycrystalline diamond (“PCD”) table bonded to the substrate. The PCD table defines an upper surface and at least one peripheral surface. The PCD table includes a plurality of bonded diamond grains. The PCD table includes a first region adjacent to the substrate that includes a metallic constituent disposed interstitially between the bonded diamond grains thereof, and a leached second region extending inwardly from the upper surface and the at least one peripheral surface that is depleted of the metallic constituent. The leached second region exhibits a leach depth profile having a maximum leach depth that is measured from the upper surface. A leach depth of the leach depth profile decreases with lateral distance from a central axis of the PCD table and toward the at least one peripheral surface.

Abstract: In an embodiment, a method for manufacturing a thin layer chromatography (“TLC”) plate is disclosed. The method includes forming a layer of elongated nanostructures (e.g., carbon nanotubes), priming the elongated nanostructures with one or more adhesion priming layers, and at least partially coating the elongated nanostructures with a coating. The coating includes a stationary phase and/or precursor of a stationary phase for use in chromatography. The stationary phase may be functionalized with hydroxyl groups by exposure to a base or acid. The stationary phase may further be treated with a silane (e.g., an amino silane) to improve the performance of the TLC plate. Embodiments for TLC plates and related methods are also disclosed.

Abstract: In an embodiment, a porous composite particulate material includes a plurality of composite particles. Each composite particle includes an acid-base-resistant core particle at least partially surrounded by one or more layers of acid-base-resistant shell particles. The shell particles are adhered to the core particle by a polymeric layer. The shell particles and/or core particles may be made from an acid-base-resistant material that is stable in harsh chemical conditions. For example, the shell particles may be made from diamond, graphitic carbon, silicon carbide, boron nitride, tungsten carbide, niobium carbide, zirconia, noble metals, combinations of the foregoing, or other acid-base-resistant materials and the core particle may include at least one exterior layer of non-diamond carbon. The porous composite particulate materials disclosed herein and related methods and devices may be used in separation technologies, including, but not limited to, chromatography and solid phase extraction.
