Abstract: One or more embodiments relate to a method for making carbon electrode material (CEM) having the steps: dispersing a carbon feedstock within a catalyst, thereby forming a mixture, wherein the catalyst is made up of particles; melting the carbon feedstock that is dispersed within the catalyst, thereby liquifying the carbon feedstock that coats catalyst particles and infiltrates spaces between the catalyst particles; carbonizing the melted carbon feedstock, thereby forming an interconnected 3D network of carbon nanosheets; converting the carbon nanosheets into graphene nanosheets; washing the graphene nanosheets, thereby forming the CEM; recovering and regenerating the catalyst. Further embodiments relate to repeating the method using recovered and regenerated catalyst.

Abstract: A method for depositing III-V alloys on substrates and compositions therefrom. A first layer comprises a Group III element. A second layer comprises a silica. A substrate has a surface. The second layer is deposited onto a first layer. The depositing is performed by a sol-gel method. The second layer is exposed to a precursor that comprises a Group V element. At least one of the precursor or the Group V element diffuse through the silica. The first layer is transformed into a solid layer comprising a III-V alloy, wherein at least a portion of the first layer to a liquid. The silica retains the liquified first layer, enabling at least one of the precursor or the Group V element to diffuse into the liquid, resulting in the forming of the III-V alloy.
