Binder-free Cu-supported Ag nanowires for aqueous rechargeable silver-zinc batteries with ultrahigh areal capacity.

As one of the most mature battery systems, the silver-zinc battery holds huge promise in the field of aqueous rechargeable batteries due to superior performance, high safety and environmental friendliness. It is urgent to improve the areal capacity of silver-zinc batteries so far. This study reports a novel Cu-supported Ag Nanowires (Cu@AgNAs abbreviation of Cu@AgNAs, Cu@AgNAs, Cu@AgNAs, Cu@AgNAs and Cu@AgNAs) as binder-free cathodes for high performance rechargeable aqueous silver-zinc batteries.

Fabrication of a SnO2-based acetone gas sensor enhanced by molecular imprinting.

This work presents a new route to design a highly sensitive SnO2-based sensor for acetone gas enhanced by the molecular imprinting technique. Unassisted and acetone-assisted thermal synthesis methods are used to synthesis SnO2 nanomaterials. The prepared SnO2 nanomaterials have been characterized by X-ray powder diffraction, scanning electron microscopy and N2 adsorption-desorption.
