Abstract: A nano-catalysts synthesis method comprises steps of: using a microplasma device to perform a microplasma treatment on a precursor solution; and purifying the precursor solution after the microplasma treatment to obtain the nano-catalysts. The microplasma has a plasma size smaller than one millimeter on at least one dimension. The precursor solution comprises a precursor and a solvent. The present invention can achieve a nano-catalysts producing method at room temperature with high efficiency and yield rate through a simple and rapid process using extremely low amount of acid or alkali solvent without introducing any toxic solvents.

Abstract: Embodiments of the present disclosure provide a method and a device for music play. The method comprises receiving a first operation instruction in a target application for playing music; in response to the first operation instruction, presenting a first interface of the target application, the first interface including an operation control for enhancing a play effect of the music through at least one processing, the processing being used for representing music content in a way more than sound; receiving a second operation instruction for the operation control; processing the music based on the second operation instruction during a process of playing the music.

Abstract: A non-pneumatic vacuum tire includes a tread layer, a carcass ply layer and a puncture-resistant airtight layer. The tread layer is provided on the carcass ply layer and located at a crown; a pattern groove is formed in a surface of the tread layer; the puncture-resistant airtight layer is fixedly provided between the tread layer and the carcass ply layer or fixedly provided under the carcass ply layer; the puncture-resistant airtight layer includes one or more layers of canvas; a warp and a weft of the canvas each are formed by a plurality of filaments; and the canvas forms the puncture-resistant airtight layer by rubber impregnation and rubber coating; the puncture-resistant airtight layer at least covers a clinch to a shoulder; and a lower end of the puncture-resistant airtight layer extends to the clinch and forms a turn-up structure.

Abstract: A protective case for folding screen phone includes a first case body, a second case body and a side stylus holder. The side stylus holder includes parallel first and seconds sides. The first side is rotatably connected to the second case body, making the second side of the side stylus holder be capable of rotating between a first position away from the first case body and a second position close to the first case body. A first groove is defined in the side stylus holder for detachably accommodating a stylus therein, and the stylus accommodated in the first groove rotates along with the side stylus holder.

Abstract: An adjustable seat includes a mount, a rotary base, a rotary fixing frame, a fixing frame transmission mechanism, and a fixing frame driving module. The rotary base is rotatably connected to the mount and is rotatable around a first rotation axis relative to the mount. The rotary fixing frame is rotatably connected to the rotary base and is rotatable around a second rotation axis relative to the rotary base. The fixing frame transmission mechanism is rotatably connected to the rotary fixing frame. The fixing frame driving module is disposed on the mount and connects with the fixing frame transmission mechanism. The fixing frame driving module drives the rotary fixing frame through the fixing frame transmission mechanism to rotate around the second rotation axis relative to the rotary base. A camera includes the adjustable seat and an image-capturing module fixed on the rotary fixing frame for capturing images.

Abstract: A protective case for mobile device includes a bottom case and a top case. The top case includes a protective case frame and a protective film. The protective case frame includes a side wall and a flange. The protective film includes a first explosion-proof film, a first adhesive disposed on a front surface of the first explosion-proof film, and a tempered glass fixed to the front surface of the first explosion-proof film by the first adhesive. The periphery of the first explosion-proof film exceeds the periphery of the tempered glass and the periphery of the first adhesive to form a protruding periphery, and the front surface of the protruding periphery is provided with a second adhesive to adhere to the back surface of the flange of the protective case frame.
