A bifunctional electrocatalyst of Co─Co2Nb5O14 with a strong interaction interface is fabricated, and a bidirectional adsorption/migration mechanism of oxygen species between the reversible active sites of Nb5+/Nb4+ has been proposed. With the catalytic strategy design, the liquid Zn‐air batteries exhibits long‐term stability over 2050 cycles, and the ...

A New X-Ray Census of Rotation Powered Pulsars
To date, over 4000 pulsars have been detected. In this study, we identify 231 X-ray counterparts of Australia Telescope National Facility (ATNF) pulsars by performing a spatial cross match across the Chandra, XMM-Newton observational catalogs.
