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.

Using processes disclosed herein, materials and structures are created and used. For example, processes can include melting boron nitride or amorphous carbon into an undercooled state followed by quenching. Exemplary new materials disclosed herein can be ferromagnetic and/or harder than diamond. Materials disclosed herein may include dopants in concentrations exceeding thermodynamic solubility limits. A novel phase of solid carbon has structure different than diamond and graphite.

In this disclosure, transition and rare earth metal-based magnetic ionic liquids (MILs) are successfully prepared in a two-step synthesis and used to extract viable bacteria from a liquid sample. The disclosed MILs are extremely hydrophobic MILs and were insoluble in aqueous solution at 0.01% (v/v). Furthermore, these MILs were miscible in a variety of polar and non-polar organic solvents. Moreover, these MILs possess low viscosity and increased magnetic susceptibility. These MILs possess unique characteristics that can have great potential uses in various chemical applications such as extraction solvents in LLE, liquid electrochromic materials (Co-based MILs), and novel reaction media for organic synthesis.
