  • Patent number: 9214678
    Abstract: Electrodes comprising metal support structures and methods for making the same are generally described. In certain embodiments, the electrodes described herein comprise a metal porous support structure, and an electrode active material at least partially contained within the pores of the porous support structure. In some embodiments, the electrical conductivity of the porous support structure material can ensure that electrons are efficiently transferred through and/or out of the electrode (e.g., to a current collector and/or to an external circuit). The pores within the porous support structure can ensure, in certain embodiments, that the electrode active material is accessible to the electrolyte, thereby enhancing performance of the electrochemical cell in which the electrode is used.

  • Patent number: 9209475
    Abstract: To increase the power generation efficiency of a microbial power generator by using an easy and inexpensive unit. Two plate-like cation-exchange membranes 31 are disposed in parallel in a tank 30. This arrangement allows an anode chamber 32 to be formed between the cation-exchange membranes 31. Two cathode chambers 33 are separated from the anode chamber 32 by using the respective ion-permeable nonconductive membranes 31. An oxygen-containing gas is made to pass through the cathode chamber 33. An anode solution L is supplied to the anode chamber, and, preferably, the anode solution is made to circulate. A biologically treated exhaust gas is used as the oxygen-containing gas to be supplied to the cathode chamber 33. Carbon dioxide in the biologically treated exhaust gas can promote transport of Na+ and K+ ions, and water vapor can increase the ion permeability, thereby increasing the power generation efficiency.

  • Patent number: 7056844
    Abstract: The present invention provides a reinforced tape including a visually transparent backing layer, a reinforcing scrim preferably of fibers made of visually transparent material along one surface of the backing, and a layer of transparent adhesive covering but not totally wetting the reinforcing scrim so that the scrim is visible along the backing layer before the tape is applied to give a user a visual indication of the strength of the tape. The indexes of refraction of the material of the fibers in the scrim and of the adhesive are similar so that when the layer of adhesive is pressed against a substrate through the backing layer, the adhesive will more totally wet the fibers of the reinforcing scrim, causing them to become significantly less visible in the reinforced tape adhered to the substrate.

The fabric is constructed as a mesh of continuously coated, high modulus of elasticity strands. The high modulus strands are preferably bundled glass fibers encapsulated by alkali and water resistant thermoplastic material. The composite fabric also has suitable physical characteristics for embedment within the cement matrix of the panels or boards closely adjacent the opposed faces thereof. The fabric provides long-lasting, high strength tensile reinforcement of the panels or boards regardless of their spatial orientation during handling. The reinforcement also enhances the impact resistance of the boards after installation. Included as part of the invention are methods for making the reinforcement, cementitious boards and panels including the reinforcement, and methods for manufacturing such boards and panels.
