Abstract: Provided are an abrasion-resistant, stable and flame-resistant superhydrophobic/superoleophobic coating, and a preparation and application thereof, belonging to the field of new materials; the preparation includes: taking a superhydrophobic/superoleophobic suspension as a top-layer spraying solution; dispersing epoxy resin in a solvent, and adding a fluorine-containing curing agent and a flame retardant for reaction to obtain a bottom-layer spraying solution; and first spraying the bottom-layer spraying solution to a surface of a substrate, then spraying the top-layer spraying solution, and drying the surface to obtain a bilayer abrasion-resistant superhydrophobic flame-resistant coating; the superhydrophobic/superoleophobic suspension contains multi-level micro nano structural particles, a fluorine-containing curing agent and fluorinated epoxy resin; the prepared single-layer coating and bilayer structure (BLC) have hydrophobicity, flame resistance, good mechanical properties and excellent corrosion resistan

Abstract: A carbon cloth/gallium oxynitride has a chemical formula of GaOxNy, where x=0.1-0.3 and y=0.7-0.9; and has a N/O molar ratio of 2.3 to 9. The carbon cloth/gallium oxynitride is a composite formed by loading gallium oxynitride nanoparticles on carbon cloth fibers, wherein the gallium oxynitride nanoparticles have a size range of 10 to 70 nm, and the carbon cloth/gallium oxynitride has a discharge specific capacitance of 30 to 865 mF cm?2 at current densities ranging from 0.5 to 100 mA cm?2. The working electrode is made from the carbon cloth/gallium oxynitride; and the supercapacitor is composed of the carbon cloth/gallium oxynitride working electrodes, a separator, an electrolyte, and an outer package.

Abstract: A system and method for downloading software is provided. When software is required to be downloaded to the mobile terminal, a software downloading tool on the computer terminal establishes a connection with the mobile terminal via a preloader port of the mobile terminal and sends a download agent to the mobile terminal. A preloader program of the mobile terminal checks whether the download agent is signed and encrypted by a private key matched with an RSA public key in the preloader program, and if yes, the mobile terminal utilizes the DA download agent to download the software. The method can effectively prevent illegal tools from having communication capability with the mobile phone by USB connection for data deletion or tampering, and reduce the possibility that a hacker damages “limiting function” of the mobile phone.
