Molecular Customization of Anode-Electrolyte Interfaces for Enhanced Stability and Reversibility in Aqueous Zinc-Carbon Capacitors.

Aqueous zinc-carbon capacitors display application potential in green power and high-end equipment owing to their high security, large power and sustainability. The water-rich zinc anode-electrolyte interface (AEI) and disordered zinc-ion diffusion are the culprits triggering corrosion reactions and dendrite growth, threatening the sustainability of aqueous zinc-carbon capacitors. Herein, a polyfunctional biomolecular, vitamin B6, is introduced into the traditional aqueous electrolyte for customizing the functional AEI and fine-regulating the interfacial coordination environment of zinc ions.

Pollinator effectiveness and importance between female and male mining bee ().

Bees are often considered to be effective pollinators in both agricultural and natural ecosystems but could be ineffective pollinators in that they collect large quantities of pollen for food provision but deliver little to stigmas. Male bees do not collect pollen to feed larvae, and their pollination role has been underappreciated. Here we compare pollination effectiveness, visit frequency and pollen foraging behaviour between female and male individuals of a mining bee, , visiting a nectariferous spring flower ().
