  • Patent number: 11905593
    Abstract: The disclosure relates to a process for preparing particulate materials having high electrochemical capacities that are suitable for use as anode active materials in rechargeable metal-ion batteries. In one aspect, the disclosure provides a process for preparing a particulate material comprising a plurality of composite particles. The process includes providing particulate porous carbon frameworks comprising micro pores and/or mesopores, wherein the porous carbon frameworks have a D50 particle diameter of at least 20 ?m; depositing an electroactive material selected from silicon and alloys thereof into the micropores and/or mesopores of the porous carbon frameworks using a chemical vapour infiltration process in a fluidised bed reactor, to provide intermediate particles; and comminuting the intermediate particles to provide said composite particles.

  • Publication number: 20140060519
    Abstract: A method of generating steam for use in an industrial process is disclosed. The industrial process may for example be power generation or desalination. The method comprises: (a) pressurising a working fluid liquid comprising water to a first pressure; (b) heating the working fluid liquid to a temperature substantially equal to the saturation temperature of the working fluid liquid at the first pressure; and (c) flash evaporating the working fluid liquid to generate steam. The pressurised working fluid liquid is heated in step (b) by direct heating in a solar radiation absorption device. Also disclosed is an apparatus for generating steam for use in an industrial process.

  • Patent number: 7756467
    Abstract: A wireless communication device includes a Near Field Communication (NFC) interface, a transceiver, and a controller. The NFC interface receives data related to multimedia content from an external NFC tag responsive to establishing an NFC link with the NFC tag. Based on the received data, the controller establishes a communication link with a multimedia server via a wireless communication network, and controls the multimedia server to download information associated with the multimedia content to a user-specified destination device.

  • Patent number: 7284855
    Abstract: Glasses for use in sports activities and the like have a frame, at least one lens formed to the frame, and a strap formed to the frame which is configured to inhibit the glasses from falling off of a wearer. A leash is formed to the strap and a collar formed to the leash. The strap, leash, collar or other component of the present invention may optionally be sufficiently buoyant so as to float the glasses in water. A breakaway clip releases the collar from a wearer if the glasses, strap, leash, or collar get caught.
