Abstract: The present disclosure provides a herbicide composition and a preparation method and an application method thereof, and relates to the technical field of herbicides. The herbicide composition includes pinoxaden and a cyclic lactone compound. The cyclic lactone compound is five-membered cyclic lactone and/or six-membered cyclic lactone. The herbicide composition solves the technical problems of poor chemical stability and precipitation due to crystallization at low temperature of existing pinoxaden emulsifiable concentrate formulations. In the herbicide composition, the cyclic lactone compound is used in combination with the pinoxaden, such that not only the solubility of the pinoxaden is improved, but also a chemical stabilization effect of the pinoxaden is effectively improved, and the problems of precipitation due to crystallization at low temperature and chemical stability of the pinoxaden emulsifiable concentrate formulations are solved.

Abstract: An anode of a battery comprises lithium metal, and a dopant, in the lithium metal. The anode has a thickness of at most 50 ?m, and the dopant is a metal with an electronegativity greater than lithium.

Abstract: Electrocatalysts composed of single atoms or metal clusters dispersed over porous carbon support were prepared by a lithium-melt method. The new catalysts demonstrated high selectivity, high Faradic efficiency and low overpotential toward to the electrocatalytic reduction of carbon dioxide to chemicals.

Abstract: A terminal, an input/output assembly and a bracket are provided. The bracket includes a body. The body includes a first face and a second face facing away from each other. The second face is provided with a plurality of accommodating chambers. The first face is provided with a plurality of through holes corresponding to the plurality of accommodating chambers. The plurality of accommodating chambers is configured to accommodate an input/output module fixedly mounted therein and to expose the input/output module from the second face. The plurality of through holes is configured to expose the input/output module from the first face.

Abstract: Disclosed is a method and device for selecting documents, such as Web pages or sites, for presentation to a user, in response to a user expression of interest, during the course of presentation to the user of a document, such as a video or audio selection, whose content varies with time. The method takes advantage of information retrieval techniques to select documents related to the portion of the temporal document in which the user has expressed interest. The method generates the search query to use to select documents by reference to text associated with the portion of the temporal document in which the user has expressed interest, as by using the closed caption test associated with the video, or by using speech recognition techniques. The method further uses a weighting function to weigh the terms used in the search query, depending on their temporal relationship to the user expression of interest.
