摘要: The present disclosure provides advantageous graphene/graphite stabilized composites (e.g., graphene/graphite stabilized emulsion-templated foam composites), and improved methods for fabricating such graphene/graphite stabilized composites. More particularly, the present disclosure provides improved methods for fabricating pristine, graphene/graphite/polymer composite foams derived from emulsions stabilized by graphene/graphite kinetic trapping. In exemplary embodiments, the present disclosure provides that, instead of viewing the insolubility of pristine graphene/graphite as an obstacle to be overcome, it is utilized as a means to create or fabricate water/oil emulsions, with graphene/graphite stabilizing the spheres formed. These emulsions are then the frameworks used to make foam composites that have shown bulk conductivities up to about 2 S/m, as well as compressive moduli up to about 100 MPa and breaking strengths of over 1200 psi, with densities as low as about 0.25 g/cm3.

摘要: A method for manufacturing a coating includes dissolving at least one salt in a mixture of water and ethanol to form a precursor solution, adding an additive to the precursor solution to form a fuel solution, and injecting the fuel solution into a plasma flame. The additive includes at least one of urea or ammonium acetate. The additive functions as a fuel to increase a temperature of the plasma flame. The method further includes manufacturing the coating on a substrate. The coating includes a garnet structure including a predetermined amount of yttrium-aluminum, one or more first cracks extending completely through a thickness of the coating, and a porosity greater than ten volume percent.

摘要: Provided are polymers, which may be crosslinked to form a main-chain liquid crystalline (LC) hydrogel with a three-dimensional network. Also provided are methods of using the hydrogel as a substrate for tissue culture. For example, the hydrogel may organize into LC phases and encapsulate a plurality of cells within its polymeric network. In some embodiments, human stem cells are cultured using the present method with good viability and demonstrate faster proliferation in the present LC hydrogel compared to a non-LC gel.

摘要: A system and method for outage prediction for electrical distribution utilities using high-resolution weather forecasts, geographic data (e.g., land use and vegetation around overhead-lines) and utility infrastructure data (e.g., transformer fuses, etc.) to predict distributed outage occurrences (e.g., number of outages over a 2-km gridded map) in advance of a storm.
