  • Publication number: 20200254527
    Abstract: Self-assembly methods are provided for making hedgehog-shaped microparticles or nanoparticles. The method may comprise combining a metal-containing (e.g., Fe, Au) precursor, a chalcogen-containing precursor (e.g., Se, S), and a self-assembly additive (e.g., dodecanethiol (DT), oleylamine (OLA), hexadecyltrimethylammonium bromide (CTAB)). At least one hedgehog-shaped nanoscale, mesoscale, or microscale particle is formed that defines a core region formed of a first material and a plurality of needles connected to and substantially orthogonal to a surface of the core region. The needles comprise a second material. At least one of the first or the second material comprises iron or gold and optionally selenium or sulfur, for example, iron diselenide (FeSe2). Hedgehog-shaped microparticles or nanoparticles formed from such self-assembly methods are also provided.

  • Patent number: 9739141
    Abstract: Disclosed is a data transmission system and a method for transmission of downhole measurement data to the ground. The system includes a drill string mounted with a logging while drilling measurement tool, and a throw while drilling section, which accommodates a micromemory. The throw while drilling section includes a housing which is mounted outside of the drill string as a sleeve to form a clearance space therebetween; a control circuit; and a wireless transceiver. The throw while drilling section releases, under function of a micromemory release instruction transmitted by the control circuit, the micromemory loaded with the downhole measurement data to the ground.

  • Patent number: 9231620
    Abstract: An iterative decoding device includes a decoder, a dual mode determination unit and a dual mode scaling unit. The decoder is utilized for receiving a set of soft information (SI) and iteratively decoding the set of SI and updating the set of SI accordingly to generate a set of updated SI. The dual mode determination unit is coupled to the decoder for generating a determination result according to the set of updated SI. The dual mode scaling unit is coupled to the dual mode determination unit and the decoder for scaling the set of updated SI according to the determination result to generate a set of scaled SI acting as an input of the decoder for next iteration.
