  • Patent number: 8754168
    Abstract: A method is provided for solubilising a membrane protein. The method is applied to cellular material comprising the membrane protein and an associated membrane lipid. A copolymer of styrene and maleic acid, wherein the styrene:maleic acid ratio is between 1:2 and 10:1, is mixed with the cellular material to cause the copolymer, lipid and protein to form soluble macromolecular assemblies.
    Type: Grant

  • Publication number: 20070095652
    Abstract: A thermal interface includes nanofibrils. The nanofibrils may be attached to a flat base or membrane, or may be attached to the tip portions of larger diameter fibers. The nanofibrils have a diameter of less than about 1 micron, and may advantageously be formed from single walled and/or multi-walled nanotubes.

  • Publication number: 20060213599
    Abstract: A fiber velvet comprising nano-size fibers or nanofibrils attached to micro-size fibers is disclosed. Methods of manufacturing the velvet as well as various uses of the velvet are also described. For example, the fiber velvet can be used as a thermal interface or as an adhesive material. The nanofibrils may be attached to a flat base or membrane, or may be attached to the tip portions of the micro-size or larger diameter fibers. Various attributes of the micro-size fibers and of the nano-size fibers, for example, geometry (e.g. size, length, packing density) material type (e.g. carbon, metal, polymer, or ceramic) and properties (e.g. conductivity, modulus, surface energy, dielectric constant, surface roughness) can be selected depending on the desired attributes of the fiber velvet. The nanofibrils have a diameter of less than about 1 micron, and may advantageously be formed from single walled and/or multi-walled carbon nanotubes.

  • Patent number: 4341174
    Abstract: A bow dock for use in a two-step docking method to allow the repair or recement of a sonar-dome rubber window on a variety of classes of full draft vessels in harbors and other water of limited depth. The bow dock is provided with docking pedestals and alignment fenders which mate with docking brackets and fenders on the vessel to be docked. Each docking pedestal is provided with an electronic load cell to monitor the pedestal load during docking. The stern gate is fitted with an auxiliary gate and inserts designed to mate with the hull configuration of each vessel class. The stern gate is also provided with a slotted pivot hinge to facilitate sealing of the stern gate to the dock by hydrostatic pressure.
