 Abstract :   

Recently we have focused on the architecture engineering of inorganic nanomaterials for their applications to fuel cell electrocatalysis, lithium ion battery, and photocatalysis. We present a synthesis of highly durable and active electrocatalysts based on ordered fct-PtFe nanoparticles for oxygen reduction reaction electrocatalysts for fuel cells.We report on the design and synthesis of highly active and stable Co-N4(O) moiety incorporated in nitrogen-doped graphene (Co1-NG(O)) that exhibits a record-high kinetic current density and mass activity with unprecedented stability (>110 h) for electrochemical hydrogen peroxide (H2O2) production.We report on the design and synthesis of highly active TiO2 photocatalysts incorporated with site-specific single copper atoms (Cu/TiO2) that exhibit reversible and cooperative photoactivation process, and enhancement of photocatalytic hydrogen generation and CO2 photoreduction activity.3 We synthesized multigrain nanocrystals consisting of Co3O4 nanocube cores and Mn3Oshells.4 At the sharp edges of the Co3O4 nanocubes, we observed that tilt boundaries of the Mn3Ograins exist in the form of disclinations, and we obtained a correlation between the defects and the resulting electrocatalytic behavior for the oxygen reduction reaction. We reported on the design and synthesis of highly stable, photoluminescent, and catalytically active suprastructures of (CdSe)13 nanoclusters.We introduced electromechanical cardioplasty using an epicardial mesh made of electrically conductive and elastic Ag/Au nanowire-rubber composite material to resemble the innate cardiac tissue and confer cardiac conduction system function.6 We fabricated highly conductive and elastic nanomembrane for skin electronics.We demonstrated a wearable red-green-blue (RGB) colloidal quantum dot light-emitting diode (QD LED) array with high resolution using a novel intaglio transfer printing technique.We also reported transparent QD LEDs with extremely high luminance and transmittance.9 We reported a novel device design and fabrication method using metal-based etch-stop layers and a laser-assisted patterning for 3D foldable quantum dot light-emitting diodes (QLEDs).10
