Open AccessSelf-adaptive amorphous CoOxCly electrocatalyst for sustainable chlorine evolution in acidic brine
Electrochemical chlorine evolution reaction is of central importance in the chlor-alkali industry, but the chlorine evolution anode is largely limited by water oxidation side reaction and corrosion-induced per...

Open AccessNon-covalent ligand-oxide interaction promotes oxygen evolution
Strategies to generate high-valence metal species capable of oxidizing water often employ composition and coordination tuning of oxide-based catalysts, where strong covalent interactions with metal sites are c...

Open AccessHydroxyl radicals dominate reoxidation of oxide-derived Cu in electrochemical CO2 reduction
Cuδ+ sites on the surface of oxide-derived copper (OD-Cu) are of vital importance in electrochemical CO2 reduction reaction (CO2RR). However, the underlying reason for the dynamically existing Cuδ+ species, altho...

Open AccessBroadening the absorption bandwidth of metamaterial absorbers by transverse magnetic harmonics of 210 mode
By investigating a square-shaped metamaterial structure we discover that wave diffraction at diagonal corners of such a structure excites transverse magnetic harmonics of 210 mode (TM210 harmonics). Multi-layer o...

Open AccessUltra-wideband microwave absorber by connecting multiple absorption bands of two different-sized hyperbolic metamaterial waveguide arrays
Microwave absorbers have important applications in various areas including stealth, camouflage and antenna. Here, we have designed an ultra-broadband light absorber by integrating two different-sized tapered h...
