A conversion-type anode with superior theoretical specific capacity and medium operating voltage is regarded as a potential solution for the next generation of high-performance lithium-ion batteries (LIBs) anode. However, practical application hindered by sluggish conversion reaction kinetics ambiguous mechanism. Herein, flexible Co9S8-carbon nanofibers composite foam (Co9S8@CF-700) unique ganglion-like architecture ingeniously designed synthesized through an electrospinning strategy. Tested...

Unavoidable complicated oxygen functionalities in porous carbons restrict identification of their electrochemically active sites. Herein, we report 3D interconnected macroporous/microporous catechol-enriched carbon through first-step low-temperature pyrolysis and second-step melted KOH etching resorcinol-formaldehyde resin its excellent pseudocapacitance. First, high-content hydroxyl groups a carbonaceous framework stem from preservation after introduction treatment. Second, molten removes...

Electrochemical water splitting is a promising strategy for reducing hydrogen production costs. However, the conventional phosphate buffer (PBS) electrolyte incurs huge energy penalty in high overpotential ranges. This study investigates evolution reaction (HER) performance using two electrolytes with different charge properties: H2 PO4–/HPO42– (PBS pKa = 6.90) and IMZH+/IMZ (IMZS 7.03). On Pt microelectrodes, results reveal that plateau current density of PBS correlates closely electrode...

Background: Air pollutants are considered non-negligible risk factors for age-related macular degeneration (AMD). However, the relationship between long-term air pollution and incidence of AMD is unknown. Our study explored associations further assessed modification effect genetic susceptibility.Methods: A land use regression model was used to estimate concentrations nitrogen dioxide (NO2), oxides (NOx), particulate matter (PM2.5, PM2.5 absorbance, PM2.5-10, PM10). The polygenic score (PRS)...
