Real-time motion intelligence from wearable systems requires efficient conversion of biomechanical energy into stable and information-rich electrical signals. However, conventional triboelectric sensors often suffer from limited interfacial polarization efficiency and unstable output under complex mechanical deformation. Here, we present a self-powered triboelectric wristband enabled by nanointer…

Aqueous Zn-metal batteries (AZMBs) are plagued by dendrite growth and parasitic reactions at the anode, limiting their commercial viability. While electrolyte additives offer promise, conventional monofunctional additives provide insufficient defense to Zn anodes. Herein, we introduce a zwitterionic 3-aminopropanesulfonic acid (APS) additive that enables an interphase-solvation dual-regulation (I…

To tackle the constraint of insufficient cathode diversity in conventional aqueous zinc-ion batteries (AZIBs), this study fabricates a C-O-Mn interface via the self-assembly of graphene nanoribbons (GNRs) with MnO, which drives the transformation of rock-salt MnO into polymorphic Mn_<i>x</i>O_<i>y</i> (including MnO₂, Mn-deficient Mn_<i>x</i>O, and MnOOH).…

With the widespread popularization of sports health concepts, the demand for intelligent sports wearable devices has become increasingly urgent. In intelligent sports systems, flexible electronics are integrated into sports equipment to construct smart wearable devices, enabling real-time acquisition and analysis of sports data and providing a scientific basis for sports performance evaluation, e…

Ferroelectric tunnel junctions (FTJs) are promising candidates for next-generation nonvolatile memories, offering fast switching, low-power operation, and scalability. However, achieving robust ferroelectricity and high tunneling electroresistance (TER) at nanometer-scale thickness remains challenging due to phase instability and interfacial degradation. Here, we report ultrathin FTJs based on a …

Hepatocellular carcinoma (HCC), a highly prevalent malignancy, is mostly diagnosed at intermediate and advanced stages. Current monotherapies are limited by poor targeting, severe toxicity, drug resistance, and high metastatic risk, necessitating more effective precision therapeutic strategies. Photothermal therapy (PTT) and ferroptosis induction are promising for HCC treatment, but violet phosph…

Artificial solid-state nanochannels have attracted significant interest as promising nanofluidic tools for ion/molecule detection, DNA sequencing, and biomimetic applications. In this work, we designed an aspartic acid-rich peptide, KD₅ (Lys-Asp₅, KDDDDD), via a green tag-assisted approach. Leveraging its strong Ca²⁺ recognition and coordination capability, KD<sub…

The increasing prevalence of antimicrobial resistance (AMR) and biofilm-associated infections represents a major challenge in both biomedical and environmental settings. Herein, we report the synthesis and comprehensive evaluation of a multifunctional nanocomposite composed of baicalein-coated Fe₃O₄/Ag nanoparticles (FAB NPs), designed to combine magnetic recoverability, con…

High-performance dielectric capacitors are essential for advancing the miniaturization of pulsed power devices. High-entropy design has recently emerged as a potent strategy for developing ceramics with superior energy storage properties. In this study, a series of lead-free (Bi_0.5Na_0.5)TiO₃-based energy storage ceramics were designed via MgO-driven high-entropy e…

Complex wounds remain a clinical challenge due to their multifaceted pathophysiology, which involves persistent inflammation, oxidative stress, tissue hypoxia, and impaired angiogenesis. To address these issues, we developed an injectable, self-healing, and conductive hydrogel based on a dual dynamic covalent network formed by cross-linking phenylboronic acid-modified oxidized hyaluronic acid (OH…

Rechargeable manganese metal batteries (MMBs) have recently gained attention owing to the high abundance, large theoretical capacity, and low redox potential (-1.19 V vs SHE) of Mn compared with Zn. However, Mn anodes suffer from severe hydrogen evolution in aqueous electrolytes, while in nonaqueous systems, corrosion suppression is accompanied by sluggish Mn²⁺ desolvation and high pol…

Surface and interfacial defects represent the primary loss pathways limiting the power conversion efficiency (PCE) and the operational stability of inverted perovskite solar cells (PSCs). Here, we report a sequential bimolecular passivation strategy employing propane-1,3-diammonium diiodide (PDAI) followed by (<i>E</i>)-[(4-trifluoromethyl)styryl]phosphonic acid (4TF) to simultaneously mitigate g…

Efficient photodynamic antibacterial activity relies on the close interfacial association between photosensitizers and bacterial surfaces. While cationic functional groups can enhance bacterial binding, they often cause nonspecific membrane disruption and substantial dark toxicity. Here, we demonstrate that engineering a mixed-charge surface on conjugated oligomer nanoparticles enables programmab…
