  • Patent number: 10567010
    Abstract: Methods and systems for encoding data are described herein. The method comprises inputting data to a first pipeline of a non-systematic polar encoder capable of encoding a polar code of length nmax, extracting, via at least one first multiplexer of size log nmax×1, a first polar code of length n<nmax at a first location along the first pipeline to generate a first encoded output, modifying the first encoded output to set frozen bits to a known value to obtain a modified first encoded output, inputting the modified first encoded output to a second pipeline of the non-systematic polar encoder, and extracting, via at least one second multiplexer of size log nmax×1, a second polar code of length n<nmax at a second location along the second pipeline to generate a second encoded output, the second encoded output corresponding to a systematically encoded polar code of length n.

  • Patent number: 10553751
    Abstract: GaN-based nanowire heterostructures have been intensively studied for applications in light emitting diodes (LEDs), lasers, solar cells and solar fuel devices. Surface charge properties play a dominant role on the device performance and have been addressed within the prior art by use of a relatively thick large bandgap AlGaN shell covering the surfaces of axial InGaN nanowire LED heterostructures has been explored and shown substantial promise in reducing surface recombination leading to improved carrier injection efficiency and output power. However, these lead to increased complexity in device design, growth and fabrication processes thereby reducing yield/performance and increasing costs for devices. Accordingly, there are taught self-organising InGaN/AlGaN core-shell quaternary nanowire heterostructures wherein the In-rich core and Al-rich shell spontaneously form during the growth process.

  • Patent number: 10495568
    Abstract: An apparatus for analysing a sample of granular material, such as soil, is described. An elongated housing has a channel extending therethrough to define an optical path. A cavity is defined within the top of the housing to receive the sample, and a transparent sample-receiving surface is disposed within the cavity at a first elevation from the bottom of the housing. A lens assembly is positioned within the optical path at a second, lower, elevation. The lens assembly magnifies an image formed by light beams reflected by or transmitted through the sample. An image capturing device is disposed across the optical path at a third elevation that is lower than the second elevation. The image capturing device is thus lower than both the lens assembly and the transparent sample-receiving surface. A light source is mounted within the housing to emit light toward the sample-receiving surface.

  • Patent number: 10407556
    Abstract: Many different substrates are used in tissue engineering as platforms to enhance cell attachment, proliferation and activity, either in-vitro, to multiply specific cell lines, or in-vivo, to induce shorter healing time of injured or missing tissue. However, their hydrophobicity and lack of specific functionalities make them non-ideal for cell adhesion and growth. Treating the surfaces by exposing them to a series of steps including, but not limited to, a diazonium based wet chemistry allows one or more functional groups to be applied to the surface improving cell adhesion and growth. Embodiments of the invention exploiting PDLLA, PMMA and roughed PEEK are demonstrated including both a one-stage and a two-stage process, and at times a vacuum treatment, allowing modification of inner and outer surfaces.

  • Patent number: 10351963
    Abstract: Important components of direct solar based nanowire enabled chemical processing and electrochemical systems are a high efficiency and highly stable photocathode and 2-photon dual electrodes. The former enables photo-excited electrons that lead to hydrogen generation whereas the later with complementary energy bandgap photoanode and photocathode enables high efficiency, unassisted solar-driven water splitting. Accordingly, it would be beneficial to leverage the high surface areas and self-contained conversion of direct solar illuminated hydrogen generation from such nanowires with multiple junctions for broad solar spectrum absorption by providing monolithically integrated multi-junction photocathodes. It would be further beneficial to provide nanowire based dual-photoelectrode systems that together with a parallel illumination scheme, can fundamentally address these critical challenges.

  • Patent number: 10329194
    Abstract: Highly mineralized natural materials often boast unusual combinations of stiffness, strength and toughness currently unmatched by today's engineering materials. Beneficially, according to the embodiments of the invention, these unusual combinations can be introduced into ceramics, glasses, and crystal materials, for example by the introduction of patterns of weaker interfaces with simple or intricate architectures, which channel propagating cracks into toughening configurations. Further, such deliberately-introduced weaker interfaces, such as exploiting three-dimensional arrays of laser-generated microcracks, can deflect and guide larger incoming cracks. Addition of interlocking interfaces and flexible materials provide further energy dissipation and toughening mechanism, by channeling cracks into interlocking configurations and ligament-like pullout mechanisms. Such biomimetic materials, based on carefully architectured interfaces, provide a new pathway to toughening hard and brittle materials.
