  • Publication number: 20150343326
    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.

  • Publication number: 20150236026
    Abstract: Recording data in a permanent solid state memory device forms voids in a patterned data layer between a first wire array and a second wire array. Wires of the first wire array extend transversely to wires in the second wire array thus creating a crossbar array. The conductive material in the data layer is made of a carbon allotrope such that when current is passed through the carbon allotrope, the carbon is quickly oxidized (burned) leaving a complete gap (void) where the conductive material (i.e., fuse) once was. One of the advantages of this method is that the fuse material is fully oxidized, such that there is no material left over from which dendrites can grow. A horizontal configuration in which the data layer is a bowtie structure is also disclosed.

  • Patent number: 8467215
    Abstract: A permanent solid state memory device is disclosed. Recording data in the permanent solid state memory device forms voids in a data layer between a first wire array and a second wire array. Wires of the first wire array extend transversely to wires in the second wire array. The data layer is at least partially conductive such that a voltage applied between a selected first wire in the first wire array and a selected second wire in the second wire array creates a heating current through the data layer at a data point between the first wire and the second wire. The heating current causes a data layer material to melt and recede to form a permanent void. Control elements are operably connected to apply voltages to predetermined combinations of wires to form permanent voids at data points throughout the solid state memory device.
