Abstract: Disclosed herein are proton transport membranes and methods of making and use thereof. The proton transport membranes comprise: a two-dimensional (2D) material having a top surface and a bottom surface; wherein the two-dimensional material comprises graphene and hexagonal-boron nitride in an atomic ratio of from 100:0 to 0:100. In some examples: the top surface is functionalized with a first functional moiety and the bottom surface is not functionalized; the top surface is functionalized with a first functional moiety and the bottom surface is functionalized with the first functional moiety; or the top surface is functionalized with a first functional moiety and the bottom surface is functionalized with a second functional moiety, the second functional moiety being different than the first functional moiety. In some examples, the two-dimensional material is doped with a substitutional dopant in an amount of from greater than 0 atomic % (at %) to less than 100 at %.

Abstract: Disclosed herein are catalytic proton transport membranes and methods of making an use thereof. The catalytic proton transport membranes comprising a two-dimensional (2D) material having a top surface and a bottom surface, wherein the top surface further comprises a catalytic material deposited thereon, wherein the membrane allows for proton transport through the membrane.

Abstract: Systems, devices, and related methods are disclosed for electromechanical transfer printing of 2D materials disposed on one substrate to another. The printing device can be configured to transfer a 2D material from a source substrate to the target substrate by applying a combination of mechanical and electrostatic forces to facilitate electromechanical adhesion between the 2D material layer and the target substrate. Some embodiments of the printing device can effect direct transfer printing of a 2D material from a source substrate to a target substrate without the use of etchants and adhesives.
