Abstract: The present disclosure relates to a differential power horizontal-vertical switchable actuator module, the differential power horizontal-vertical switchable actuator module including: an actuator which rotates a horizontal drive shaft formed in the horizontal direction as a whole; a first gearbox which is connected to one side end of the horizontal drive shaft and transfers rotational power from the one side of the horizontal drive shaft by switching the direction to a first vertical rotation shaft that is in the vertical direction as a whole; and a second gearbox which is connected to the other side end of the horizontal drive shaft and transfers rotational power from the other side of the horizontal drive shaft by switching the direction to a second vertical rotation shaft that is in the vertical direction as a whole.

Abstract: A transfer stamp comprising a nano-film layer is formed on a substantially transparent polymeric substrate, wherein the substantially transparent polymeric substrate comprises an indirect adhesion layer adhered to the nano-film. The nano-film layer of the transfer stamp is applied to a surface of a target substrate; the nano-film layer is positioned between the indirect adhesion layer and the target substrate.

Abstract: A two-dimensional film (such as graphene) is formed on a surface of a growth substrate. A first surface of the two-dimensional film adheres to the growth substrate, and a second surface of the two-dimensional film is then coated with a conforming carrier layer comprising ethylene vinyl acetate. The surface of the growth substrate is etched to release the two-dimensional film with the conforming carrier layer from the growth substrate, wherein the conforming carrier layer maintains the integrity of the two-dimensional film during and after its release from the growth substrate. The first surface of the two-dimensional film with the conforming carrier layer coating is then applied onto a target substrate to form a graphene coating on the target substrate. The conforming carrier layer is then removed from the two-dimensional film by exposing the conforming carrier layer to a solvent while the two-dimensional film is coating the target substrate.
