Amorphous clusters are gaining prominence as prospective hosts for sodium-ion hybrid capacitors (SIHCs), but their efficacy is still affected by atomic coordination. Optimization of ion storage and charge transport can be achieved through high coordination and bimetallic configurations. Herein, high-coordination amorphous P-Nb-W-P (Nb/W-P) clusters are skillfully tailored by bridging Nb into the second shell of W in the W-P configuration, nested in situ in conductive and stable N, P co-doped carbon nanospheres (Nb/W-P@NPC).

As a potential alternative to next-generation LIBs, carbonous materials have garnered significant attention as anode materials for potassium-ion batteries due to their low cost and environmental friendliness. However, carbonaceous materials cannot fulfill the demand of anode for PIBs, due to volume expansion and poor stability during charging/discharging process. It is well-known that N doping can provide active sites for K-storage, and expand the layer distance between graphite layers.

In high-resolution mass spectrometry, an electrospray ionization source is often paired with an ion-funnel to enhance ion transmission. Although it is established that ions experience collision-induced dissociation as they pass through this device, the impact of gas-flow dynamics on ion fragmentation remains unexplored. The present work demonstrates that the gas-flow dynamics from the capillary interface of an electrospray ionization source into an ion-funnel significantly reduces ion fragmentation.
