Abstract: A method for producing graphene, configured for forming a graphene layer on a surface of an object. The method includes steps of: depositing a poly-p-xylene material layer on the surface: and converting the poly-p-xylene material layer into a graphene layer by using a laser sintering process or a plasma-assisted sintering process.

Abstract: A method of manufacturing decoration foils and a release layer and an adhesive layer of the decoration foil, and decoration foils manufactured by the same are revealed. First take waste containing polyethylene terephthalate (PET) to react with an alcohol and get a first product. Then the first product is allowed to react with a compound containing isocyanate group and polyol to obtain polyurethane (PU) material. The PU material obtained is used for manufacturing at least one of a release layer and an adhesive of decoration foils to get the decoration foil.

Abstract: A control module and an electronic device having the same are disclosed. The control module includes a control panel, a return component, and a conductive element. The control panel includes a conductive port. The return component is disposed on the control panel. The return component includes a first end and a second end, and the return component is electrically contacted with the conductive port. The conductive element includes a first sidewall and a second sidewall. The conductive element is electrically contacted with the first end or the second end.

Abstract: A flash module including a main body, a fixing base, a rotating structure, a switch and a linking structure is disclosed. The rotating structure is movably connected between the main body and the fixing base. The switch has a moving part. The linking structure is connected between the rotating structure and the moving part. The linking structure moves the moving part to an open position from a close position and rotates the rotating structure, so that the main body is moved relative to the fixing base.

Abstract: A light-emitting device may include a heat-dissipating base, a light-emitting unit, a housing, and a first conductive contact and a second conductive contact. The heat-dissipating base has a top portion and a bottom portion. The bottom portion of the heat-dissipating base may include an exposed heat-dissipation surface. The light-emitting unit is over the top portion of the heat-dissipating base and is arranged to provide heat conductivity at least from the light-emitting unit to the heat-dissipating base. The light-emitting unit may include at least one light-emitting diode for emitting light and a first electrode and a second electrode. Heat may be generated as the light-emitting diode emits light, and the at least one light-emitting diode may have power input terminals for receiving power input to the at least one light-emitting diode. The power input may include one of an alternating-current input and a direct-current input.
