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.

A non-woven carbon fiber reinforced thermoplastic (CFRTP) composite object is formed by the variable frequency microwave (VFM) irradiation of a mixed fiber sheet of thermoplastic fibers, carbon fibers and wavy carbon nanotubes (CNTs). The mixed fiber sheets are prepared from a slurry of the thermoplastic fibers, carbon fibers, and wavy CNTs such that the wavy CNTs contact the carbon fibers and thermoplastic fibers. Upon irradiation with VFM radiation, the wavy CNTs generate heat and transfer the heat to the thermoplastic fibers, causing melting of the thermoplastic to form the matrix of the CFRTP composite object. The mixed fiber sheets can be combined alone or with other sheets to form laminar composites that are molded into objects and heated by VFM irradiation.

A method of fabricating a carbon nanotube ('CNT') array includes providing a substrate with a CNT catalyst disposed on a surface of the substrate, heating the CNT catalyst to an annealing temperature, exposing the CNT catalyst to a CNT precursor for an exposure period to pre-load the CNT catalyst, and exposing the pre-loaded CNT catalyst to a carbon source for a growth period to form the CNT array. The formed CNT array comprises a plurality of CNT bundles that are aligned with one another in an alignment direction. At least one of the plurality of bundles comprises an average structural factor of 1.5 or less along an entirety of the length thereof.

Atomically thin layers including pores, their method of manufacture, and their use are disclosed. In some embodiments, pores may be formed in an atomically thin layer by growing the atomically thin layer on exposed portions of a substrate that includes islands comprising a material that is different than the material of the substrate. In some embodiments, pores and/or defects may be formed in an atomically thin layer by employing growth conditions that promote the formation of defects and/or pores. In certain embodiments, pores and/or defects may be etched to enlarge their size.

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.
