Abstract: In an embodiment, the present disclosure pertains to a supercapacitor composed of a cathode material, a gel electrolyte, and a zinc foil anode. In some embodiments, the cathode material, the gel electrolyte, and the zinc foil anode are in a multilayered configuration. In some embodiments, the cathode and anode materials provide load-bearing capability. In an additional embodiment, the present disclosure pertains to a method of making a supercapacitor. In general, the method includes fabricating a cathode material, preparing a gel electrolyte, coating a zinc foil electrode with the gel electrolyte, and sandwiching the zinc foil electrode with the cathode material. In some embodiments, the sandwiching forms a multilayered configuration composed of the cathode material, the gel electrolyte, and the zinc foil anode.

Abstract: In an embodiment, the present disclosure pertains to a metal oxide-coated nanofiber yarn. In some embodiments, the metal oxide-coated nanofiber yarn includes a plurality of twisted carbon nanofibers. In some embodiments, each twisted carbon nanofiber includes a porous hollow fiber. In some embodiments, each twisted carbon nanofiber includes metal oxide nanoparticles coated on a surface thereof. In some embodiments, an outer surface of each twisted carbon nanofiber, an inner surface of each twisted carbon nanofiber, and holes or channels of a main fiber skeleton of the plurality of twisted carbon nanofibers with the possibility of transferring a metal ion are covered by the metal oxide nanoparticles. In a further embodiment, the present disclosure pertains to methods of making the metal oxide-coated nanofiber yarn. In an additional embodiment, the present disclosure pertains to a structural supercapacitor utilizing the metal oxide-coated nanofiber yarn.

Abstract: A method for manufacturing graphene-based materials includes (a) positioning graphite into an inner chamber of a rotatable housing of a rod mill. A plurality of elongate rigid rods are loosely positioned in the housing. In addition, the method includes (b) rotating the housing of the rod-mill after (a). Further, the method includes (c) rod milling the graphite with the rods during (b) to produce a first portion of the graphene-based materials and milled graphite. The first portion of the graphene-based materials include 30 layers or less of graphene and the milled graphite comprises more than 30 layers of graphene.

Abstract: Disclosed herein are MXene-aromatic thermosetting copolyester nanocomposites. In one aspect, the nanocomposites can be used to fabricate and/or coat artificial bone implants. In another aspect, the nanocomposites are biocompatible and/or nontoxic. Implants and coatings formed from the nanocomposites possess excellent compressive strength, hardness, and wear resistance in synovial fluid when compared to current implant coatings and materials.
