  • Patent number: 10811680
    Abstract: A battery comprises electrodes formed from the same metal oxide and an electrolyte solution comprising a source of cations which can be intercalated into the metal oxide. The battery can store electrical charge by connecting one of the electrodes to an external power source to reduce at least some of the metal atoms in the metal oxide forming the electrode from a higher to a lower oxidation state through the uptake of intercalating cations from the electrolyte and thereby create a potential difference between the electrodes, which electrical charge can be discharged by electrically connecting the electrodes. The electrodes are preferably formed from a multi-valent transition metal oxide, such as a tungsten, vanadium, cobalt or molybdenum oxide, more preferably tungsten trioxide. The intercalating cations are preferably protons and the electrolyte an acid.

  • Patent number: 9236352
    Abstract: A semiconductor wafer has a plurality of semiconductor die. A peripheral region is formed around the die. An insulating material is formed in the peripheral region. A portion of the insulating material is removed to form a through hole via (THV). A conductive material is deposited in the THV to form a conductive THV. A conductive layer is formed between the conductive THV and contact pads of the semiconductor die. A noise absorbing material is deposited in the peripheral region between the conductive THV to isolate the semiconductor die from intra-device interference. The noise absorbing material extends through the peripheral region from a first side of the semiconductor die to a second side of the semiconductor die. The noise absorbing material has an angular, semi-circular, or rectangular shape. The noise absorbing material can be dispersed in the peripheral region between the conductive THV.

    Abstract: A method of making a reconfigurable three-dimensional shape includes the following steps: (i) moving multiple print heads in three dimensions relative to a printing surface, where the print heads include a conductor print head and a polymer print head; (ii) depositing a conductive material from the conductor print head; and (iii) depositing a shape-memory polymer from the polymer print head. The depositing steps form a volumetric shape of a shape-memory polymer, capable of changing shape, with a conductive material capable of acting as a heating element integrally formed in the volumetric shape. The method can further include the steps of heating the shape-memory polymer above a transition temperature, changing the shape of the volumetric shape following the heating step, and then allowing the shape-memory polymer to cool below the transition temperature to fix the new volumetric shape.

  • Publication number: 20150118599
    Abstract: A method of fabricating composite filaments is provided. An initial composite filament including a core and a cladding (such as a Pt-group metal) is cut into smaller pieces (or is first mechanically reduced and then cut into smaller pieces). The smaller pieces of the filaments are inserted into a metal matrix, and the entire structure is then further reduced mechanically in a series of reduction steps. The process can be repeated until the desired cross sectional dimension of the filaments is achieved. The matrix can then be chemically removed to isolate the final composite filaments with the cladding thickness down to the nanometer range. The process allows the organization and integration of filaments of different sizes, compositions, and functionalities into arrays suitable for various applications.
