Parallelization has revolutionized computing and DNA sequencing but remains largely unexploited in mass spectrometry (MS), which typically analyzes ions sequentially. We introduce a nature-inspired ion trap (MultiQ-IT) that enables massively parallel MS. The device comprises a cubic array of small quadrupoles forming multiple ion entry and exit ports, allowing >10⁹ ions to be confined and manipulated simultaneously. This architecture enables selective depletion of singly charged ions in real time, greatly improving signal-to-noise ratios and detection sensitivity. The trap also functions as a parallel ion splitter, transmitting ions into multiple m/z-specific beams. We demonstrate scalable ion throughput, real-time charge discrimination, and parallel beam separation, suggesting a path toward truly parallel MS. Our results offer a foundation for next-generation, high-throughput proteomic and metabolomic analyses.

Achieving efficient ion transport in thick electrodes remains a fundamental challenge in electrochemical systems with high energy density, primarily due to prolonged diffusion pathways and poorly integrated architectures. Leveraging the nanoconfinement effect, (sub)nanoscale channels can significantly accelerate ion transport kinetics to maximize electrochemical performance. Inspired by the hierarchical network structure of bamboo membrane, a gradient nanoconfined MXene electrode (GNC-MX) is designed, where multiscale interlayer spacing is coupled with in-plane mesopores that bridge adjacent nanoconfined channels, enabling synergistic vertical and horizontal ion migration.

Lithium metal negative electrodes are highly promising for high-specific-energy batteries due to their low electrochemical potential and high capacity. However, dendrite growth due to limited Li transport at the interface hinder their performance and safety. Enhancing interfacial Li transport can prevent Li depletion and ensure uniform Li deposition.

Supramolecular hydrogels assembled from natural herbal small molecules represent a promising platform for the development of biocompatible and multifunctional soft biomaterials. In this study, we report a novel multicomponent supramolecular hydrogel system constructed from the co-assembly of glycyrrhizic acid (GA) and rhein (Rh) Zn modulation. The introduction of Zn not only reinforces the mechanical stiffness and toughness of the GA-Rh hydrogel network through complexation but also improves its antibacterial efficacy and anti-inflammatory capacity.

Hydrogel electrolytes are regarded as a promising option for high-performance aqueous zinc-ion batteries (ZIBs), but they frequently fail to balance the reaction kinetics and Zn deposition stability. Inspired by articular cartilage, here we develop a gradient-networked hydrogel electrolyte comprising poly(vinyl alcohol) (PVA), cellulose nanofiber (CNF), and graphene oxide (GO) for ZIBs. The low-network-density PVA/CNF (PC) hydrogel layer (cathode side) with extensive channels and a higher water content ensures the rapid transport of ions, while the interfacial hydrogel layer in contact with the Zn anode exhibits a high-density PVA/CNF/GO (PCG) network with enriched carboxyl and hydroxyl groups, which facilitates the desolvation of Zn, decreases the activity of water, and homogenizes the Zn flux.
