Quercetin (Qu), a naturally occurring flavonoid, is critically involved in sustaining human physiological health. Therefore, it is imperative to rationally design a proficient electrochemical sensor capable of sensing Qu. Herein, a ternary nanocomposite composed of Keggin-type polyoxometalate (PMo 12 ), carbon nanotubes (CNTs), and zirconium-based MOF (UiO-66-NH 2 ) was successfully fabricated to develop a sensitive electrochemical sensor for Qu determination. Benefiting from the synergistic integration of diverse components, the high conductivity of CNTs, good electrocatalytic performance of PMo 12 , and favorable adsorption capacity of UiO-66-NH 2 jointly facilitated the adsorption and electron transfer process of Qu at the electrode interface. The constructed sensor showed a broad linear detection range of 10–160 μM, high detection sensitivity reaching 0.226 μA·μM −1 , and a detection limit as low as 0.486 μM (S/N = 3) at the optimized working conditions. Besides, the developed sensor exhibited outstanding selectivity, stability, reproducibility, and repeatability. By determining the Qu content in Flos Sophorae Immaturus samples, we further confirmed the actual application capability of the constructed sensor. Satisfactory recoveries of 97.01%–101.08% were obtained, which strongly validated the reliability and accuracy of the proposed electrode for practical Qu analysis.

K 0.5 MnO 2 @Na 0.7 MnO 2 composite is prepared by a KCl@Na 2 CO 3 molten salt. • Electrochemically induced conversion of KMO@NMO into K-doped NMO is achieved. • K doping enhances structural stability of NMO and facilitates Na + migration. • KMO as K + supply source compensates K + loss in NMO upon cycling. • KMO@NMO shows high capacity retention after 800 cycles. P2-type layered Na 0.7 MnO 2 is regarded as a promising cathode material for sodium-ion batteries due to its high specific capacity. However, Mn 3+ -induced Jahn-Teller distortion and Mn 2+ dissolution result in the structural instability of Na 0.7 MnO 2 , thereby restricting its large-scale application. In this study, a K 0.5 MnO 2 @Na 0.7 MnO 2 composite is prepared by a molten salt method and used as a cathode. In particular, partial K + in K 0.5 MnO 2 substitutes for the Na + sites in Na 0.7 MnO 2 during the charge-discharge process, which decreases the Mn 3+ /Mn 4+ ratio and provides wide Na + channels, achieving fast reaction kinetics and long-term cycling stability. The persistent K 0.5 MnO 2 throughout the entire testing process works as a robust K + supply source and compensates for the K + loss of K-doped Na 0.7 MnO 2 during cyclic tests. Consequently, the cathode shows a high discharge capacity of 148 mA h g −1 at 0.04 A g −1 and outstanding cycling stability, with a capacity retention of 69% after 800 cycles at 0.5 A g −1 . This research provides important references for designing high-performance layered cathode materials in sodium-ion batteries.

One-step MXene/CNTs-COOH/CS/IL sensing interface was constructed. • CNTs-COOH alleviated MXene restacking and promoted electron transport. • CS and ionic liquid enhanced metal-ion enrichment and ionic transport. • The sensor simultaneously determined Cd 2+ , Pb 2+ , Cu 2+ , and Hg 2+ . • Real-water results agreed well with ICP-MS measurements. Rationally coordinating ion accessibility, electron transport, metal-ion enrichment, and film stability within a facile electrode architecture remains challenging for multiplex electrochemical analysis. Herein, an MXene-based multicomponent sensing interface was constructed through the one-step integration of carboxylated carbon nanotubes (CNTs-COOH), chitosan (CS), and an ionic liquid (IL) with Ti 3 C 2 T x nanosheets. CNTs-COOH act as conductive nano-spacers that alleviate MXene restacking and improve electronic connectivity, while CS provides coordination-active amino and hydroxyl groups for metal-ion enrichment and contributes to film stability. The incorporation of IL improves component dispersion and ionic transport and partially mitigates the interfacial transport limitation associated with the CS-containing layer. Structural and electrochemical characterization results collectively support complementary roles of the four components in regulating interfacial accessibility, analyte accumulation, and charge-transfer behavior. Under the optimized conditions, the resulting electrode enabled the simultaneous determination of Cd 2+ , Pb 2+ , Cu 2+ , and Hg 2+ by differential pulse anodic stripping voltammetry over linear ranges of 0.5–22.5, 0.5–60, 0.5–87, and 0.5–62 μM, respectively. The corresponding detection limits were 0.1539, 0.0746, 0.2279, and 0.0931 μM. The sensor also exhibited satisfactory selectivity, reproducibility, and long-term stability, retaining approximately 92–95% of its initial response after 30 days. Recoveries of 92.2–96.0% were obtained in spiked tap-water and river-water samples, and the measured concentrations were consistent with those obtained by ICP-MS. These results demonstrate a functionally coordinated interface-engineering strategy for the simultaneous electrochemical determination of multiple heavy metal ions.

Developing transparent terahertz (THz) absorbers that simultaneously achieve strong electromagnetic attenuation and high optical transmittance remains challenging. Despite the pronounced THz dielectric responses in aqueous ionic systems, the structural origins of energy dissipation and their quantitative link to ion-water interactions remain insufficiently resolved. This study systematically quantifies ion-water interaction strength in various ionic solutions and correlates it with water-state distribution and THz dielectric dissipation. Our findings indicate that weaker ion-water interactions are associated with enhanced conductive and dissipation pathways. Guided by this correlation, we designed a polydimethylsiloxane (PDMS)-encapsulated CsCl hydrogel with a thickness of only 0.14 mm, which achieves an average reflection loss of 52.24 dB and an effective absorption bandwidth (EAB) covering 0.3–1.2 THz, while maintaining over 90% optical transmittance and high mechanical deformability. This work provides a structure-informed strategy for the rational design of transparent THz absorbing materials.

Adaptive bioelectronics that autonomously adjust to environmental changes represent an emerging paradigm, enabling reliable operation across diverse conditions. Hypoxic microenvironments are prevalent across numerous pathological conditions including chronic wounds, tumors, and ischemic tissues, creating a fundamental challenge: oxygen-dependent enzymatic biosensors fail precisely when monitoring is most critical, while oxygen deficiency simultaneously impairs tissue regeneration. We present a soft wireless Hypoxia-Adaptive Sensing and Therapeutic (HAST) system that maintains reliable biosensing functionality in oxygen-deficient environments through integrated oxygen management. Using engineered poly(3,4-ethylenedioxythiophene):poly(styrene sulfonate) (PEDOT:PSS)/polydopamine (PDA)/enzyme biocomposites, HAST integrates multiplexed biosensing (glucose, uric acid, lactate) with dual-oxygen provision: wound exudate-triggered dissolved oxygen generation restores biosensor functionality while electrical stimulation promotes vascular regeneration for sustained tissue oxygenation. This hypoxia-adaptive design achieves about 10-fold biosensor sensitivity enhancement under oxygen-deficient conditions while promoting tissue repair. In preclinical diabetic wound models, HAST enabled accurate continuous monitoring with ∼30% accelerated wound closure, demonstrating environment-adaptive bioelectronics for precision medicine in oxygen-deficient pathological conditions.

Developing a sustainable and cost-effective counter electrode (CE) material with high catalytic activity is of significant importance for quantum dot-sensitized solar cells (QDSSCs). In this work, by using the industrial residue material of sulfonated asphalt as the carbon precursor, we prepared a CoFe/CoFe 2 O 4 embedded N, S-doped carbon hybrid (CoFe/CoFe 2 O 4 @C) and applied to the CE of QDSSC. Structure analyses indicated that CoFe/CoFe 2 O 4 @C has a porous structure with large surface area. Electrochemical investigations revealed that the CoFe/CoFe 2 O 4 @C possesses high catalytic activity for polysulfide reduction. Consequently, CdSe QDSSC based on CoFe/CoFe 2 O 4 @C CE achieved a high power conversion efficiency (PCE) of 6.37%, significantly superior to the commonly used PbS CE (5.4%). This study provides a sustainable strategy for converting the industrial residue material of asphalt into a low-cost and high-performance CE material for QDSSC.

Restacked two-dimensional (2D) material thin films offer a promising approach for achieving high volumetric energy density supercapacitors, but their ultimate rate performance is constrained by electrolyte ion transport properties. This work systematically investigates the electrochemical behaviors and underlying mechanisms of restacked 1T−MoS 2 films in various aqueous electrolytes. In 1 M CsCl electrolyte, an 8.5-μm-thick 1T−MoS 2 film electrode exhibits ultrafast ion storage kinetics with a b -value of 0.94 and a remarkable volumetric capacitance ( C v ) of 221 F cm −3 at 1,000 mV s −1 , significantly outperforming other ionic systems. The electrode also demonstrates excellent cycling stability with 87% capacitance retention after 10,000 cycles at 10 A g −1 . Compared to reported advanced graphene, MXene, and oxide-based electrodes, the 1T−MoS 2 film electrodes in 1 M CsCl show an integrated advantage of ultrathin characteristic and ultrahigh C v under considerable high scan rates of 500 to 1,000 mV s −1 . Theoretical calculations reveal that Cs + possesses the lowest diffusion barrier between 1T−MoS 2 interlayers, where its weak solvation effect facilitates rapid ion storage kinetics. This work not only elucidates the ultrafast transport mechanism of Cs + within confined 2D spaces, but also provides insights into developing next-generation ultrafast energy storage devices with high volumetric energy densities through optimized electrolyte–electrode synergy. The electrochemical ion storage behaviors and underlying mechanisms of restacked 1T−MoS 2 film electrodes in various aqueous electrolytes were systematically investigated. The electrodes exhibit ultrafast charge storage kinetics in 1 M CsCl, demonstrating the combined advantages of ultrathin feature and ultrahigh volumetric capacitance at scan rates as high as 1000 mV s −1 , significantly outperforming state-of-the-art reported electrode materials.

Novel Eu 3+ -doped Cs 2 KInCl 6 double perovskite exhibits ultrabroadband emission, enabling efficient multicolor luminescence covering the entire visible spectrum with a single luminescent center. This behavior originates from the intrinsically low phonon energy of the host, which effectively suppresses multi-phonon relaxation (MPR) and consequently reshapes the radiative pathways of Eu 3+ . As a result, its stepwise population accumulation occurs along the excited-state energy ladder, promoting multiple radiative transitions. Based on this kinetic behavior, the rare coexistence of blue ( 5 D 3 → 7 F 4 ), green ( 5 D 2 → 7 F 3 ), yellow ( 5 D 1 → 7 F 2 ), and red ( 5 D 0 → 7 F 2 ) emissions are achieved with large emission cross-sections of 2.00 × 10 −22 , 4.75 × 10 −22 , 5.48 × 10 −22 , and 8.18 × 10 −22 cm 2 , respectively. These emissions are further validated by high fluorescence branching ratios exceeding 40%, confirming the efficiency of the corresponding radiative channels and their collective contribution to multipeak full-spectrum emission. In addition, the phosphors demonstrate pronounced thermal responsiveness in the temperature range of 303 – 433 K, together with dynamically tunable emission, supporting their applications in high-sensitivity optical thermometry, dynamic anti-counterfeiting, and high-quality lighting. Overall, this work suggests that ultralow-phonon-energy perovskite provides an effective platform for achieving multiple excited-state radiative transitions, thus offering a research foundation for developing functional optical materials and next-generation photonic devices.

Bio-derived FAD acts as a small-molecule light-driven oxidase mimic. • FAD exhibits wavelength-selectivity by responding only to blue and UV light. • Oxygen-dependent blue-light-driven and oxygen-independent UV-driven modes. • H 2 O 2 -free, metal-free colorimetric sensor achieves visual detection of nitrite. • A sensor enables sensitive detection with precise spatiotemporal control. Natural enzymes are constrained by poor stability and structural fragility, while existing enzyme mimics predominantly exhibit an “always-on” mode lacking spatiotemporal controllability. Herein, it was discovered that bio-derived flavin adenine dinucleotide (FAD), the core cofactor of natural photoenzymes, exhibits intrinsic light-driven oxidase-mimicking activity under blue and ultraviolet (UV) light. Notably, FAD operates in an oxygen-dependent mode under blue light and an oxygen-independent mode under UV light, enabling its application in various complex scenarios. Leveraging the superior biocompatibility and application potential of the blue-light mode, a novel colorimetric sensor for nitrite detection was successfully constructed. FAD catalyzes the oxidation of 3,3′,5,5′-tetramethylbenzidine (TMB) to blue oxTMB under blue light, and nitrite triggers the diazotization of oxTMB to generate yellow diazo-TMB, enabling visual detection for nitrite through color change. The colorimetric sensor achieves a wide linear range of 40–440 μM, with a low limit of detection (LOD) of 1.93 μM. Moreover, the sensor exhibits excellent anti-interference capability and satisfactory recoveries (85.0%–103.5%) in real water samples. This work establishes FAD as a bio-derived light-driven oxidase mimic, providing a new strategy for designing efficient, wavelength-selective enzyme mimic and opening a new avenue for advanced light-driven sensors with precise spatiotemporal control. A facile strategy employs bio-derived flavin adenine dinucleotide (FAD), which exhibits intrinsic light-driven oxidase-mimicking activity, enabling the construction of a metal-free, spatiotemporally controllable colorimetric sensor for nitrite detection.

Photocatalytic immunotherapy has attracted significant attention due to high selectivity and low side effects. However, the poor tissue penetration of ultraviolet-visible light and the low energy of near-infrared (NIR) photons, combined with the immunosuppressive tumor microenvironment (TME), severely limit catalytic efficiency and immune activation. In this study, we designed a gradient Zn 2 + -doping polymeric carbon nitride (PCN) nanocatalyst (gZn-PCN@M), in which the Zn 2 + concentration gradually decreases from the interior to the surface of the PCN nanosheets. Under 808 nm laser irradiation, gZn-PCN@M catalyzes the decomposition of H 2 O in tumor interstitial fluid to produce hydrogen gas, which reduces the intratumoral delivery resistance, markedly enhancing the penetration depth of gZn-PCN into tumors. Meanwhile, the acidic TME and laser irradiation further promote Zn 2 + release from gZn-PCN, resulting in abnormally elevated intracellular Zn 2 + levels that triggers ROS bursts and disrupts tumor energy metabolism, thereby downregulating PD-L1 expression in tumor cells and activating antitumor immune responses. The results indicated that the inhibition rates of gZn-PCN on primary tumors and distant tumors were 96.51% and 83.69%, respectively. This study proposes a gradient ion-doping strategy for the first time to enhance the NIR responsiveness of photocatalytic nanomedicines, combined with metabolic interference to achieve efficient tumor photocatalytic immunotherapy.

The enantioselective recognition of biomolecules such as amino acids has significant value in medicine, life sciences, agriculture, and other fields. In this study, a novel electrochemical chiral sensor, CS@Cu-β-CD/GCE, was successfully prepared by self-assembling Cu 2+ modified β-cyclodextrin (β-CD) with chitosan (CS) and coating it onto a glassy carbon electrode (GCE). This method effectively addresses the agglomeration issues associated with CS while significantly enhancing the conductive properties of the material and increasing the number of chiral recognition sites. Experimental testing and structural analysis revealed that differentiated hydrogen bonding provides the driving force for molecular binding, while the confinement of the Cu-β-CD cavity and steric hindrance enable structure selection. At optimized testing conditions (30 s incubation, 25°C, pH = 6.0, 5.0 mM), it exhibited the peak current ratio (I D /I L ) of up to 2.25 for phenylalanine (Phe) isomers, outperforming most previously reported electrochemical sensors. Meanwhile, the CS@Cu-β-CD/GCE exhibits excellent stability (98.6% signal retention after 16 days of storage at 5°C), high enantiomeric selectivity for Phe, and good resistance to interference, can be developed for distinguishing racemic phenylalanine. This strategy provides a simple and efficient approach for electrochemical chiral identification of Phe enantiomers and holds wide-ranging application prospects in chiral sensing and drug analysis.

Fluorine-doped tin oxide (FTO) is a cornerstone transparent conducting oxide in electrochemistry and materials science, yet its stability is often assumed rather than verified. This work presents a time-resolved operando investigation into the degradation of the FTO electrode, quantitatively mapping its chemical and electrochemical stability in acidic (0.5 M H 2 SO 4 ), neutral (1.0 M KCl), and alkaline (1.0 M KOH) environments. By employing time-resolved electrochemical impedance analysis and cyclic voltammetry-coupled electrochemical impedance spectroscopy protocol, we simultaneously track changes in FTO resistance and double-layer capacitance to deconvolve distinct degradation mechanisms. Our findings reveal that FTO stability is highly conditional. Alkaline media are universally corrosive, causing severe surface roughening (capacitance increases >90 %) and conductivity loss even during simple chemical immersion. In contrast, under acidic and neutral conditions, cathodic cycling drives surface roughening, whereas anodic cycling leads to surface smoothing. Most notably, the impact on conductivity is potential-specific: anodic polarization improves conductivity in neutral KCl but is destructive in KOH, where stannate (SnO 3 2− ) formation causes the largest rise in resistance (+7.3 %). By correlating electrical parameters with specific redox processes, this study provides a quantitative framework for understanding FTO degradation and establishes critical operating windows to ensure FTO reliability in electrochemical applications.
