Abstract: Disclosed herein are methods for forming a graphene film on a substrate, the methods comprising depositing graphene on a surface of the substrate by a first vapor deposition step to form a discontinuous graphene crystal layer; depositing a graphene oxide layer on the discontinuous graphene crystal layer to form a composite layer; and depositing graphene on the composite layer by a second vapor deposition step, wherein the graphene oxide layer is substantially reduced to a graphene layer during the second vapor deposition step. Transparent coated substrates comprising such graphene films are also disclosed herein, wherein the graphene films have a resistance of less than about 10 K?/sq.

Abstract: An elevation adjusting mechanism used for ascending or descending a monitor includes a base, a first thread bushing, a second thread bushing, a guiding bushing and a second gear. The first thread bushing including a first gear is movably connected to the base. The second thread busing is connected to the first thread busing. One end of the first thread bushing is contained in the second thread bushing. The monitor is disposed on the second thread busing. The guiding bushing is fixed at the base and covers the second thread bushing, so that the second thread bushing only moves along an elevating direction. The second gear is movably connected to the guiding busing and meshes with the first gear. When the second gear is rotated and drives the first thread bushing to rotate, the second thread busing moves along the elevating direction to ascend or descend the monitor.
