“UTRGV-UMN Partnership for Fostering Innovation by Bridging Excellence in Research and Student Success” DMR 1523577 Karen Lozano, The University of Texas Rio Grande Valley [A] Developed a scalable method to produce graphene-fiber hybrid structures with seamless connections between graphene and fibers. These are produced in situ from aqueous polymer solutions. The surface area and pore diameter of the hybrid structures were measured to be 520 m2g–1 and 10 nm, respectively. The resulting structure shows high electrical conductivity, 550 S/m, and promising shielding of electromagnetic interference, making it an attractive system for a broad range of electronic applications. [B] Ternary nanofibers permit cell proliferation even in the presence of TNF-a. When grown with 10% serum supplementation, 3T3 mouse embryonic fibroblasts show robust growth on ternary composite nanofibers, even in the presence of cytokine TNF-a. This suggests that nanofibers may act to sequester inflammatory cytokines, thus promoting wound healing in diabetics (Project directed by Robert Gilkerson).
