  • Patent number: 12258656
    Abstract: The present invention relates to a magnesium alloy material, which is an in situ magnesium hydroxide nanosheet layer modified magnesium alloy. The material is prepared from a magnesium alloy through a hydrothermal reaction under alkaline condition. The protective effect of the in situ formed magnesium hydroxide nanosheet layer structure results in remarkably enhanced corrosion resistance of the magnesium alloy, meanwhile the biocompatibility can also be significantly improved since the release rate of magnesium ion can be significantly reduced. In addition, the two-dimensional nanolayer structure has a non-releasing physical antibacterial property depending on contact. Therefore, the magnesium alloy material according to the present invention has an extremely great application prospect in the field of medical implant.

  • Publication number: 20210361786
    Abstract: Disclosed are a material with supercapacitance modified surface and a preparation method and application thereof. Specifically, the present disclosure introduces a material having a controllably supercapacitive surface. The surface is chargeable, the full-charged modified surface can interact with bacteria disturbing the electron transfer of respiratory chain of bacteria and inhibiting the growth and reproduction of bacteria in a short-term. The antibacterial rate can be improved by cyclically charging-discharging without losing capacitance, and prevent formation of biofilm of bacteria. The antibacterial system can quantitatively control the antibacterial process without affecting the biocompatibility of the material, and has the advantages of environmental protection and controllability.

  • Patent number: 9698024
    Abstract: Some embodiments of the present disclosure relate to a method to increase breakdown voltage of a power device. A power device is formed on a silicon-on-insulator (SOI) wafer made up of a device wafer, a handle wafer, and an intermediate oxide layer. A recess is formed in a lower surface of the handle wafer to define a recessed region of the handle wafer. The recessed region of the handle wafer has a first handle wafer thickness, which is greater than zero. An un-recessed region of the handle wafer has a second handle wafer thickness, which is greater than the first handle wafer thickness. The first handle wafer thickness of the recessed region provides a breakdown voltage improvement for the power device.
