Abstract: The present application provides a handheld intelligent electronic fountain device, comprising a housing, a storage bin for storing consumables, a heating component for heating consumables, an ejection tube for ejecting consumables outward, and an air supply component for delivering compressed air into the ejection tube, so as to prompt consumables to be ejected out of the ejection tube. The present application provides a first material guiding tube and a first rotating shalt, a first threaded portion for guiding material is provided at one end of the first rotating shaft, and a second threaded portion is provided at other end of the first rotating shaft, and the second threaded portion is threadedly connected with a first transmission gear.

Abstract: Provided is a preparation method for an ultrahigh-conductivity multilayer single-crystal laminated copper material, where multiple layers of single-crystal copper foils are laminated together to form a laminate, and the laminate is pressurized and annealed as one piece by performing pressurizing and high-temperature annealing at the same time, or the laminate is pressed as one piece by means of direct hot rolling, thereby obtaining an ultrahigh-conductivity multi-layer single-crystal laminated copper material, whereby, according to the method, multiple layers of single-crystal copper foils are used as raw materials, an ultrahigh-conductivity multi-layer single-crystal laminated copper material is prepared by means of hot rolling or pressing and annealing, and the conductivity of the copper material is greater than or equal to 105% IACS.

Abstract: An information input method, a terminal, and a non-transitory computer-readable storage medium are disclosed. The method includes controlling a bottom modal view to be displayed on a current user interface, in response to receiving a first instruction configured for indicating a state in which first information is to be received, the bottom modal view being a floating layer page displayed on the current user interface, having an area less than that of the current user interface, and comprising a first input widget; and controlling the first information to be input based on an input signal in response to the first input widget being triggered.

Abstract: A method for clonal-growth of a single-crystal metal, including: using copper as an example, placing an existing small-sized single-crystal copper foil with a plane of any index on a copper foil that needs to be single-crystallized, and performing annealing to obtain, by cloning, a large-area (in meters) single-crystal copper foil with the same surface index as that of the parent facet. The method solves the difficult problem of large-area single-crystal copper foil preparation. By performing annealing, a parent single-crystal copper foil with a very small size (˜0.25 cm2) can be cloned to produce a large-area (˜700 cm2) single-crystal copper foil, which is an increase in area of about 3000 times.
