| Abstract Scope |
Heterogeneous assembly and integration of nanostructures or nanostructure arrays onto various surfaces, interfaces, and substrate carriers presents a rich spectrum of opportunities for designing and engineering various functional application platforms or devices. Such a heterogeneous integration practice involves a critical scaling exercise across atomic scale and engineered ensembles. Self-assembly and integration processes may be adapted in this practice to combine and organize dissimilar building blocks such as particles, wires, and films made of metals, ceramics, or polymers. In this talk, I will highlight our latest progress on the metal oxide and metal based structural integrations toward multiscale devices and systems, specifically on the nano-engineered reactors and sensors for CO2 conversion and H2 production. These latest examples depart from nanoarray based catalytic converters, nanomanufacturing, to catalytic water electrolysis, CO2 conversion, inline molecule separation and sensing, forming a close-loop nanomaterials engineering roadmap for achieving a sustainable energy and the environmental ecosystem. |
