  • Patent number: 10745272
    Abstract: A microscale device may include a patterned forest of vertically grown and aligned carbon nanotubes defining a carbon nanotube forest with the nanotubes having a height defining a thickness of the forest. The patterned forest may define a patterned frame that defines one or more components of the microscale device. The microscale device may also include a conformal coating of substantially uniform thickness extending throughout the carbon nanotube forest. The carbon nanotube forest may have a thickness of at least three microns. The conformal coating may substantially coat the nanotubes, define coated nanotubes and connect adjacent nanotubes together such that the carbon nanotube forest is sufficiently robust for liquid processing, without substantially filling interstices between individual coated nanotubes. The microscale device may also include a metallic interstitial material infiltrating the carbon nanotube forest and at least partially filling interstices between individual coated nanotubes.

  • Publication number: 20160118077
    Abstract: An optical tape data storage is disclosed. An optical tape includes a substrate in a linear thin film shape and a recording layer deposited on the substrate. An irreversible optically detectable change is formed in the recording layer upon application of energy to the recording layer such that data is recorded on the recording layer by forming optically detectable changes. The recording layer may comprise a metal, a metal alloy, a metal oxide, a metalloid, or any combination thereof. The optical tape may further include an adhesion promotion layer for improving adhesion of the recording layer and the substrate, a reflective layer for providing optical contrast to an adjacent layer, and/or an absorptive layer positioned adjacent to the recording layer to absorb ablatable material not entirely ablated during ablation.

  • Patent number: 9283541
    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), 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 acidified water vapor or immersion in a concentrated acid bath (e.g., HCl and methanol). At least a portion of the elongated nanostructures may be removed after being coated. Embodiments for TLC plates and related methods are also disclosed.
