  • Patent number: 11107630
    Abstract: Various embodiments of the present disclosure are directed towards a piezoelectric metal-insulator-metal (MIM) device including a piezoelectric structure between a top electrode and a bottom electrode. The piezoelectric layer includes a top region overlying a bottom region. Outer sidewalls of the bottom region extend past outer sidewalls of the top region. The outer sidewalls of the top region are aligned with outer sidewalls of the top electrode. The piezoelectric layer is configured to help limit delamination of the top electrode from the piezoelectric layer.

  • Patent number: 9450242
    Abstract: A method for manufacturing a nanostructured metal oxide calcinate suitable for biosensor through a procedure of redox reaction is disclosed in this invention. The nanostructured metal oxide calcinate is free of impurities and produced with better electrocatalytic activity and better conductivity. Thus, an electrode of biosensor can be modified via the nanostructured metal oxide calcinate. The method for manufacturing the nanostructured metal oxide calcinate includes: disposing a first metal material and a second metal material into a reaction slot and making the first metal material and the second metal material dissolved within a solvent to form a mixture, wherein the pH value of the mixture ranges between 0 to 7, the mixture performs a redox reaction process for obtaining a metal oxide material; and eventually calcining the metal oxide material for obtaining a nanostructured metal oxide calcinate.

  • Patent number: 9431258
    Abstract: A method for photodepositing a particle on a graphene-semiconductor hybrid panel is disclosed. The method for photodepositing the particle on the graphene-semiconductor includes providing a graphene-semiconductor hybrid panel, dipping the graphene-semiconductor hybrid panel in a fluid containing a precursor, and irradiating the graphene-semiconductor hybrid panel using a light source until the precursor has been reduced or oxidized to form a particle photodeposited on a surface of a graphene sheet. The graphene-semiconductor hybrid panel includes a semiconductor substrate and the graphene sheet adhered to the semiconductor substrate. The light source has an energy equal to or higher than a band gap of the semiconductor substrate. As such, the particle can be directly deposited on the surface of the graphene sheet without the need of modifying the graphene.

  • Patent number: 8877119
    Abstract: Nanocomposites of multi-phase metal oxide ceramics have been produced from water soluble salts of the resulting metal oxides by a foaming esterification sol-gel method. The evolution of volatile gases at elevated temperature during the esterification reaction causes the formation of a foam product. Nanocomposites of multi-phase metal oxide ceramics have also been produced by a cation polymer precursor method. In this second method, the metal cations are chelated by the polymer and the resulting product is gelled and foamed. Calcination of the resulting foams gives nanocomposite powders with extremely fine, uniform grains and phase domains. These microstructures are remarkably stable both under post-calcination heat treatment and during consolidation by hot-pressing.

  • Patent number: 8556786
    Abstract: A thigh exerciser includes a U-shaped frame having a space formed between two levers, a retaining member coupled between the levers for connecting and retaining the levers of the frame together, and a spring biasing member having two arms engaged with the levers and secured to the levers respectively for securing the spring biasing member to the levers of the frame. The frame includes a projection extended from each of the levers for engaging with the arms and for securing the arms of the spring biasing member to the levers of the frame. The spring biasing member includes a channel formed in each of the arms for slidably and adjustably engaging with the projection of the lever.
