Abstract Industrial oily wastewater discharges and marine oil spills pose a serious threat to ecosystems. A new strategy for efficient and controllable oil–water separation is provided by smart-responsive wettability materials, owing to their ability to dynamically switch surface wettability in response to external stimuli. Under this premise, we reviewed the research progress and applications of…

Abstract Quasi-solid-state electrolytes (QSEs) are critical for ultrafast-charging yet high-safety sodium metal batteries (SMBs), yet their implementation is hindered by sluggish Na + transport in bulk and at interfaces. Here, we propose dual interlocked mediator engineering that transcends conventional independent approaches by coupling cationic Sn 2+ salt with anionic difluoro(oxalato)borate (D…

Abstract Fully stretchable hydrogel-based moisture-electric generators (FSHMEGs) are promising power sources for wearable and implantable electronics. Current FSHMEGs are constrained by low electrical output and mechanical fragility, mainly due to weak interfacial adhesiveness within multilayered architectures. Here, we introduce an intrinsically adhesive hydrogel that forms robust hydrogel-elect…

Abstract A stable cathode–electrolyte interphase (CEI) significantly enhances the durability of lithium-ion batteries; however, the intricate chemistry underlying its formation makes predesign exceedingly challenging. This work demonstrates that surface oxygen vacancy (OV) concentration dually regulates CEI thickness and composition. We develop an in situ strategy where Li 2 C 4 O 4 incorporation…

Abstract Achieving highly linear and sensitive strain sensing under both tensile and compressive deformation remains a critical challenge in wearable electronics, as it demands a conductive network capable of reversible reconfiguration without compromising structural uniformity. This challenge is further intensified in hierarchical carbon nanostructures, where catalyst deactivation and unregulate…

Abstract Annealing is a crucial step for recrystallizing Sb 2 S 3 and forming high-quality Sb 4 S 6 chain-like crystals, which is essential for achieving high-efficiency photovoltaic devices. However, this process currently faces a fundamental trade-off: Although high-temperature annealing enhances crystallinity, it also introduces severe sulfur and Sb 2 S 3 molecular escape, ultimately degrading…

Abstract Traditional powder-type electromagnetic absorbers have become inadequate against the intensified radiation across broader frequency ranges, induced by the proliferation of intelligent communication devices.

Abstract Diabetes aggravates postoperative tumor recurrence and impairs wound healing due to divergent metabolic adaptations to hyperglycemia in tumor versus normal cells. Current therapeutics fail due to the incapabilities in adaptively modulating the metabolic bifurcation across the contradictory pathological contexts. Here, we address this challenge by developing a platinum (Pt) single-atom na…

Hypertrophic scars, characterized by excessive fibroblast activation, present significant clinical challenges. Current treatments (e.g., laser, surgery, steroids) face limitations: Surgery is costly and associated with high recurrence rates, while pharmacological interventions often induce pain and exhibit low bioavailability or efficacy. To address this, we engineered a novel chiral supramolecul…
