A new and generic strategy to construct interwoven carbon nanotube (CNT) branches on various metal oxide nanostructure arrays (exemplified by V2O3 nanoflakes, Co3O4 nanowires, Co3O4–CoTiO3 composite nanotubes, and ZnO microrods), in order to enhance their electrochemical performance, is demonstrated for the first time. In the second part, the V2O3/CNTs core/branch composite arrays as the host for...
A novel flexible and lightweight Fe2O3-based lithium-ion battery anode has been developed by growing porous α-Fe2O3 nanorods onto carbon nanotubes–graphene foam (CNT–GF). The CNT–GF 3D network provides a highly conductive, high surface areas and lightweight scaffold for the active Fe2O3 nanorods. Such unique electrodes for lithium-ion battery exhibit an 80% initial columbic efficiency, high-rate capabilities,...
Nanomaterials are often functionalized with biological ligands to enable their use as sensors of biological activity. However, the intricacies of nano-bio interactions are poorly understood, which hampers our ability to design nanomaterial-based sensors. Current experimental tools have been unable to visualize interactions occurring on the nano-bio interface with the spatial and temporal resolution...
