摘要： A patterned magnetic graphene made from the steps of transferring or growing a graphene film on a substrate, functionalizing the graphene film, hydrogenating the graphene film and forming fully hydrogenated graphene, manipulating the extent of the hydrogen content by using an electron beam from a scanning electron microscope to selectively remove hydrogen, wherein the step of selectively removing hydrogen occurs under a vacuum, and forming areas of magnetic graphene and non-magnetic graphene. A ferromagnetic graphene film comprising film that has a thickness of less than two atom layers thick.

摘要： A method of lithographic masking for spatially localized biochemical stimulus delivery, comprising the steps of providing a group of cells on a substrate, coating a layer of gelatin on a portion of the cells, creating a mask layer on a portion of the layer of gelatin on a portion of the cells, and creating an area of masked cells and an area of unmasked cells. Further, the method can include delivering a biochemical signal to the area of unmasked cells, removing the mask layer, and allowing the cells with the biochemical signal and the cells without the biochemical signal to interact freely.

摘要： A method of graphene-enabled block copolymer lithography transfer to an arbitrary substrate comprising the steps of applying graphene on a surface, adding block copolymers to the graphene on the surface, phase-separating the block copolymers, forming nanopatterned phase separated block copolymers, delaminating the graphene, and transferring the graphene and nanopatterned phase separated block copolymers to a second surface. A layer of nanopatterned phase separated block copolymers on an arbitrary surface comprising a first arbitrary substrate absent of chemical preparation, a layer of graphene on the first arbitrary substrate, and a layer of phase-separated block copolymers on the layer of graphene, wherein the layer of phase-separated block copolymers on the layer of graphene was formed on a second substrate and delaminated via water liftoff and wherein the nanopatterned phase separated block copolymers are utilized as a shadow mask for lithography on the first arbitrary substrate.
