Transport fingerprints of aqueous electrolytes are captured to be mediated by environment-reconstructed ion correlation networks.

Taking the Nernst–Einstein deviations as descriptors, electrolyte transport presents threefold-hierarchical variations due to salt concentration, thermal effect, and nanoconfined interface.

This threefold-hierarchical framework is transferable among diverse electrolytes, offering a localized insight for electrolyte evaluation in electrochemical energy devices.

Inorganic high-performance fibers (IHPFs)-based composites development and electromagnetic interference (EMI) shielding mechanisms are reviewed.

Surface modification strategies for IHPF’s surface inertness challenge and EMI shielding layer construction are summarized.

Future directions and current challenges for achieving large-scale, durable, and environmentally stable IHPF-based EMI shielding materials are outlined.

The fading mechanisms of different kinds of state-of-the-art aqueous battery cathodes including manganese/vanadium-based material, chalcogen and halogen materials, Prussian blue analogues, as well as Ni(OH)₂ cathodes were summarized.

Recent progresses on electrolyte engineering on the stability of cathode materials such as bulk electrolyte modification, electrolyte additives, water-in-salt electrolytes, and hydrogel electrolytes were systematically reviewed.

The issues that should be concerned in future electrolyte design for highly state aqueous battery cathodes were proposed.

Monodisperse and substitute Co were doped into edge-sharing [IrO₆] octahedra of Ca₂IrO₄ model catalyst, which usually present the intrinsic and strong stability for acid oxygen evolution reaction (OER)

The optimized Janus Co–Ir local structure triggers spin balance effect with optimal e_g¹ orbital and uneven t_2g orbital despite the large crystal field of Ir, which co-promote the OER activity with a relatively stable crystal structure.

Different from the slowly kinetics of adsorbates evolution mechanism on Ca₂IrO₄, superoxide path mechanism occurs on Co doped Ca₂IrO₄ based on the assignment of *OO on dual active sites of Ir and Co.

The hydrogel achieves an ultra-light water-based structure (0.041 g cm⁻³, 52.7 wt% water) by incorporating hollow foaming microspheres.

Sealed air pockets enable ultra-low thermal conductivity (0.034–0.039 W m⁻¹ K⁻¹) and over 50 °C thermal shielding under high-temperature conditions.

High solar reflectance (0.94) and infrared emittance (0.84) deliver up to 10.8 °C sub-ambient outdoor cooling.

We report an ambient single-step laser-driven process that simultaneously synthesizes and integrates prelithiated silicon nanoparticles into a robust graphene matrix using simple precursors.

Prelithiation is achieved in situ through interfacial solid-state reactions between Si and common lithium salt precursors during the ultrafast photothermal graphitization of phenolic resin.

Prelithiated silicon nanoparticles/laser-induced graphene anodes exhibit exceptional cycling stability (> 98% capacity retention after 2000 cycles) and near-zero performance decay in Li-ion half and full cells compared to non-lithiated counterparts.

Dual-function molecular ligand (MA) can coordinate with Pb²⁺ to passivate defect at grain boundaries and undergoes in-situ polymerization to form a stress-buffering network.

Attributing to the simultaneous defect suppression and strain homogenization, the MA-modified perovskite solar cells demonstrate high photovoltaic performance with power conversion efficiency up to 26.42% (rigid) and 25.03% (flexible).

The MA-modified devices demonstrate excellent stability under various environmental stress conditions, including thermal aging, light irradiation, and bending.

Wafer-scale, kinetically controlled self-assembly combined with edge-controlled lift-off enables uniform and precisely patterned nanomaterial films on 8-inch wafers.

HfO₂ interface passivation eliminates wet etching failures and ensures reliable integration with suspended microelectro-mechanical systems (MEMS) structures.

A “film-first, cantilever-later” strategy realizes 3D MEMS gas sensing chips with accurate nanomaterial incorporation, delivering high H₂ sensitivity and uniformity.

Bionic self-assembly strategy forms bulk supramolecular nanohelices and interfacial dynamic bilayers to enhance ion transport and interfacial stability.

Reinforced asymmetric cells exhibit a high coulombic efficiency of 99.66% over 2400 cycles, while the corresponding full cells retain 86% of their initial capacity after 1000 cycles, demonstrating outstanding electrochemical stability and durability.
