Tri-metallic CoCuMoO x oxides were prepared as efficient glucose sensor. • The high-valence Mo 6+ can act as an electron acceptor for glucose oxidation. • A new pathway for Co 2+ and Cu 2+ to oxidize glucose was activated by Mo 6+ . The accurate and efficient non-enzymatic detection of glucose remains a significant challenge. This study reports a novel tri-metallic CoCuMoO x oxide synthesized via the co-deposition of Co 2+ and Cu 2+ on electrochemical oxidation derived MoO x as sensitive glucose sensor. The incorporated Co 2+ and Cu 2+ bring real active sites Co 2+/3+ , Co 3+/4+ , and Cu 2+/3+ redox couples for electrochemical oxidation of glucose. More importantly, the inactive Mo 6+ can activate the Co 2+ and Cu 2+ sites for glucose oxidation by acting as an electron acceptor. Due to the new pathway activated by Mo 6+ , the optimized CoCuMoO x @CC electrode exhibits superior glucose sensing performance, including a high sensitivity of 5958.7 μA·mmol −1 ·cm −2 in the linear range of 10 μmol to 1 mmol, a rapid response time of 3 s, a low detection limit of 2.2 μmol, and superior anti-interference performance. Meanwhile, the electrochemical measurements show good long-term stability of CoCuMoO x @CC electrode, with 92.5% of the original current remained at the 28th day. This work not only develops a promising non-enzymatic glucose sensing material but also advances the material design principles for glucose sensors based on high-valence transition metal ions. The incorporated Co 2+ and Cu 2+ bring real active sites Co 2+/3+ , Co 3+/4+ , and Cu 2+/3+ for electrochemical oxidation of glucose. More importantly, the inactive Mo 6+ can activate the Co 2+ and Cu 2+ sites for glucose oxidation by acting as an electron acceptor.

This study proposes the combination of copper sulfide‑carbon nanotubes (CuS-CNTs) photothermal material with paraffin/expanded graphite. A flat-plate collector based on this material is also designed. Unlike traditional collectors that integrate phase change materials, the composite phase change material in this design can directly absorb sunlight and store heat. The goal is to reduce heat loss from the collector and improve system stability and efficiency. The novelty of this study lies in the preparation of a composite phase change material with high photothermal conversion efficiency, high thermal conductivity, and good shape stability. This material can realize the integration of photothermal conversion and thermal energy storage inside the collector. Key results show that when the CuS-CNTs content is 10%, the photothermal conversion efficiency of the composite phase change material increases from 61.07% to 94.03%. The total efficiency of the solar water heating system reaches as high as 56%. These results indicate that the addition of CuS-CNTs can significantly improve the photothermal conversion efficiency of the material. The prepared composite phase change material has great application prospects in the field of solar energy. In addition, this work uses numerical simulation for analysis. The optimal parameter combination for the collector is determined as an upper layer material density of 0.8 g/cm 3 , a lower layer material density of 0.8 g/cm 3 , and a thickness ratio of 1:1. These findings provide reference and guidance for the structural design of high-performance flat-plate collectors.

Background Emerging pollutants such as enrofloxacin (ENR) pose a serious threat to the ecosystem and public health due to their resistance to degradation and tendency to accumulate in the environment. Although existing antibiotic detection techniques have considerable application value, they suffer from high costs, complex operation procedures, or insufficient sensitivity. Therefore, there is an urgent need to develop a new detection method that is simple, rapid, low-cost, and environmentally friendly to efficiently monitor antibiotic pollution in environmental water bodies and safeguard public health. Results In this work, inspired by the superior catalytic activity of three-dimensional (3D) composite nanomaterials, we rationally designed and synthesized FeMoO 4 /Fe 7 S 8 nanosheet flower composites (3D FeMoO 4 /Fe 7 S 8 NSFs) as a novel peroxidase-mimicking nanozyme for the sensitive colorimetric detection of ENR. The as-synthesized NSFs exhibit outstanding intrinsic peroxidase-like activity, enabling their direct integration into a colorimetric sensing platform. Critically, the synergistic redox coupling between Mo 6+ /Mo 4+ and the Fe 2+ /Fe 3+ couple facilitates rapid electron transfer, thereby promoting efficient activation of peroxymonosulfate (PMS) to generate reactive oxygen species—including hydroxyl radicals (·OH), sulfate radicals (·SO 4 − ), singlet oxygen ( 1 O 2 ), and superoxide radicals (·O 2 − ), which collectively drive the oxidation of chromogenic substrates without requiring external enzymatic or chemical initiators. This mechanism underpins a robust, single-step colorimetric assay that overcomes key limitations of conventional methods, such as stringent temperature control, prolonged reaction times, and narrow pH operational windows, thus enabling rapid, reliable ENR quantification. The optimized sensing platform delivers a wide linear range (0.500–70.0 μM), a low detection limit (LOD) of 0.150 μM (S/N = 3), and a total assay time of only 5 min. Significance This system breaks through the limitations of traditional methods in terms of temperature, time, and pH conditions, and successfully generates free radicals and non-free radical active substances by activating PMS, thereby achieving rapid and efficient detection of antibiotics. This innovation provides a highly promising new strategy for the identification of fluoroquinolone (FQs) antibiotics and shows broad application prospects in the field of environmental pollutant detection and monitoring.

To meet the demand for high-efficiency energy storage of supercapacitors, it is important to develop binder-free electrodes. As an electrode material, transition metal sulfides are one of the research hotspots in this field. Herein, the Ni 3 S 2 @CoS x /NF electrode has been fabricated in situ on nickel foam via a combination of electrodeposition and hydrothermal methods. SEM analysis reveals that the Ni 3 S 2 nanosheets are dispersed on the surface of CoS x with a hollow dodecahedron structure. Moreover, there is a heterogeneous interface between Ni 3 S 2 and CoS x . The electrochemical measurements with Ni 3 S 2 @CoS x /NF directly serving as the positive electrode demonstrate that the Ni 3 S 2 @CoS x /NF presents a good electrochemical energy storage performance. That is, the Ni 3 S 2 @CoS x /NF electrode exhibits a high areal capacitance of 8100 mF·cm −2 at 1 mA·cm −2 and retains 74% of its initial capacitance after 5000 cycles at 20 mA·cm −2 . An asymmetric supercapacitor using Ni 3 S 2 @CoS x /NF as the positive electrode and activated carbon (AC) as the negative electrode achieves an areal energy density of 270 μWh·cm −2 at a power density of 800 μW·cm −2 . Meanwhile, the mechanism for the improvement of the electrochemical performance of Ni 3 S 2 @CoS x /NF is further analyzed.

The dilemma of biological contamination and radiation pollution deriving from the widely used implantable monitor equipment and wearable electronics promotes the growing demand for integrated biological and electromagnetic protection materials. This work proposes Oxalis -mimicking nanosheet arrays of MoS 2 /Au on carbon cloth (CC@MoS 2 /Au) to exert a “kill three birds with one stone” effect. First, the biomimetic architecture imparts the planar substrate with mechano-bactericidal property, which is dependent on attractive interactions between sharp edges and adhered bacteria. Second, the integration of MoS 2 /Au nanohybrids triggers a photo-bactericidal mode, and the coupling of Au nanoparticles guarantees smooth fulfillment for higher photocatalytic efficacy. Such a synergistic action allows for a nearly 100% inactivation efficiency toward E. coli and S. aureus . Third, the engineered CC@MoS 2 /Au exhibits electromagnetic interference shielding effectiveness exceeding 40 dB in X band, equivalent to 99.99% impeding of incident waves. This work reported here to design of multifunctional platforms with antibacterial and electromagnetic interference shielding performance, which may create a powerful support to mitigate the issues of biological contamination and electromagnetic pollution in the field of modern healthcare.

Hafnium (Hf) has emerged as a promising element for next-generation computed tomography (CT) contrast agents owing to its high X-ray attenuation coefficient and favorable biocompatibility. However, scalable synthesis of Hf-based imaging probes with sufficiently high metal content for large-animal preclinical studies remains challenging. Here, we report a facile air-assisted pyrolysis strategy for the gram-scale synthesis of Hf-rich carbon dots (Hf-rCDs). The resulting Hf-rCDs exhibit a high Hf content (40.7%), robust batch productivity (>2 g per batch), ultra-small hydrodynamic size (∼3.2 nm), excellent aqueous solubility (up to 600 mg mL − 1 ; 244 mg Hf mL − 1 ), and superior X-ray attenuation performance. Importantly, Hf-rCDs demonstrate rapid renal clearance within 2 h post-injection, supporting a favorable biosafety profile. In vivo CT imaging reveals outstanding contrast enhancement across multiple physiological systems, including the circulatory, urinary, gastrointestinal, and lymphatic systems. Notably, Hf-rCDs enable high-resolution visualization of cervical vasculature in swine, highlighting their strong translational potential. Collectively, these results establish Hf-rCDs as a compelling alternative to conventional iodine-based contrast agents for advanced CT imaging.

The hydrogen evolution reaction (HER) in alkaline media is a promising strategy for sustainable hydrogen production, but the exploration of efficient and durable HER electrocatalysts is often hindered by the empirical and time-consuming nature of traditional synthesis. Herein, a machine learning (ML)–driven strategy combining Bayesian optimization is introduced to achieve the rational design of Ni 3 S 4 /Ni 3 Mo heterostructures for alkaline HER. By coupling predictive modeling with experimental feedback, this approach efficiently navigated a complex synthesis space and identified conditions yielding a structurally and electronically optimized catalyst. The optimized Ni 3 S 4 /Ni 3 Mo exhibits a vibrant morphological evolution—from compact buds to blooming petal-like structures—enabling enriched active sites and accelerated mass transport. Guided by Bayesian optimization, the optimized Ni 3 S 4 /Ni 3 Mo achieves a 10.5-fold enhancement in C dl and delivers an exceptionally low overpotential of 18.2 mV at 100 mA cm −2 , outperforming most reported transition-metal catalysts and even surpassing commercial Pt/C. Mechanistic insights from in situ Raman and DFT reveal that interfacial charge redistribution between Ni 3 S 4 and Ni 3 Mo optimizes H* adsorption (Δ G H* ≈ 0.04 eV) and significantly reduces the water-dissociation barrier (0.08 eV), thereby accelerating reaction kinetics. This work demonstrates how the ML-guided optimization can synergistically couple morphology control, interfacial engineering with electronic tuning, offering a generalizable framework for intelligent catalyst discovery and mechanistic understanding in electrochemical energy conversion.

The lower thermodynamic potential of the urea oxidation reaction (UOR) makes it an ideal alternative to the conventional oxygen evolution reaction (OER). However, most Ni-based UOR catalysts face intrinsic limitations due to the high oxidation potential of Ni3+, coupled with insufficient selectivity. Herein, F/Mo codoped Ni-based catalyst F-MoNiP is obtained with an amorphous nanotube structure. The F/Mo codoped strategy enhances UOR activity by facilitating the formation of catalytically active NiOOH species at low overpotential and simultaneously promotes urea decomposition through the environmentally preferred carbonate pathway. Moreover, the presence of F effectively suppresses the OH– adsorption, thereby minimizing the competition with OER. This synergistic optimization enables F-MoNiP to achieve exceptional catalytic performance, operating at a cell voltage of 1.395 V to deliver a current density of 10 mA cm–2 in urea-assisted electrolysis of water. These findings offer a sustainable and energy-efficient route for hydrogen production through urea electrolysis.

Heterophase junction engineering offers a revolutionary strategy for constructing polymorph photocatalysts with nearly perfect interfacial matching, thereby significantly optimizing charge dynamics. Nevertheless, existing heterophase junction systems still struggle to achieve both directional charge separation and efficient utilization of the full solar spectrum. In this study, a wurtzite-phase Cu2ZnSnS4 (W-CZTS)/kesterite-phase Cu2ZnSnS4 (K-CZTS) S-scheme heterophase junction was successfully constructed through the precise regulation of the spatial assembly between W-CZTS nanoparticles and K-CZTS nanosheets. This strategic structural design achieved three key breakthroughs: (i) the formation of atomically intimate interfaces with strong built-in electric fields, (ii) the integration of superior photothermal conversion capability, and (iii) directional charge separation while preserving optimal redox potentials. The developed heterophase junction catalyst demonstrated outstanding photothermal-assisted photocatalytic performance: under UV–vis–IR illumination, the average CO yield reached 68.4 μmol g–1 h–1, which represented a 9.6-fold enhancement compared to that without IR irradiation, and 76-fold and 114-fold higher than the performance of pristine K-CZTS and W-CZTS, respectively, under UV–vis irradiation. Furthermore, the catalyst demonstrated near-complete removal efficiency for both Cr(VI) reduction and Congo red degradation. This study establishes a paradigm for the development of high-performance heterophase junction photocatalysts and provides crucial insights for advancing solar-driven environmental remediation and fuel production.

2-Chloro-4-nitrophenol (2C4NP) is a traditional organic pollutant whose toxicity constitutes a significant threat to both human health and environmental safety. Therefore, developing a method for the accurate detection of 2C4NP in natural environments is imperative. Consequently, we develop a photoelectrochemical sensing platform based on MWCNTs@In2S3/In2O3/GCE in this work. During the construction process, it is discovered that the introduction of MWCNTs accelerated the electron transport rate, which improved the separation efficiency of photogenerated electron–hole pairs in In2S3. Meanwhile, the MWCNTs@In2S3/In2O3 composite materials formed by MWCNTs@In2S3 and In2O3 not only exhibit an S-scheme heterojunction but also preserve the intrinsic advantages of MOFs-derived materials. This synergistic structure endows the composite materials with excellent optoelectronic performance and adsorption capability. Thus, the constructed photoelectrochemical sensing platform demonstrates promising potential for detecting 2C4NP, with a linear detection range from 3 nM to 5 μM. However, compared to some existing platforms, its detection range remains relatively narrow, which may represent an area for future improvement.

The self-assembly of nucleotides into sophisticated biomolecular architectures offers a powerful platform for developing advanced functional materials. Herein, we exploit the innate chirality and metal-coordination capability of nucleotides to fabricate biomolecular coordination polymers with circularly polarized luminescence (CPL). By integrating nucleotides (AMP, GMP, UMP, CMP) with lanthanide-based deep eutectic solvents (DESs) that serve as both a reactive medium and a source of red and green emission, we successfully constructed nucleotide-lanthanide coordination polymers. These biomolecular complexes not only exhibited characteristic lanthanide emissions but also demonstrated significant CPL activity. Remarkably, a white-light-emitting coordination polymer with white circularly polarized luminescence (W-CPL) was achieved by incorporating blue-emitting carbon dots into the AMP-coordinated system, forming a solvent-free supramolecular assembly. Furthermore, a prototype light-emitting diode (LED) device was fabricated by coating these nucleotide-based complexes onto a UV chip, successfully generating electrically driven polarized visible light. This work underscores the immense potential of nucleotide biomolecules as versatile scaffolds for crafting next-generation polarized optical materials and devices.

Structural engineering of electromagnetic wave absorbing (EMWA) materials faces critical challenges in scalable fabrication and multifunctional integration. Herein, a flexible and sustainable bamboo-based composite (BMXMo) featuring engineered microcapacitor-Schottky heterostructures is proposed to synergize ultra-efficient K-band microwave absorption with self-powered health monitoring. The heterostructure is constructed by assembling conductive Ti 3 C 2 T x MXene electrodes and 1T/2H-MoS 2 dielectric nanoflowers within a densified bamboo matrix. The heterostructure optimizes impedance matching while enhancing multi-scale polarization via interfacial/dipolar effects and Schottky-modulated charge trapping. The optimized BMXMo 55 film exhibits exceptional EMWA performance, with an ultra-high reflection loss of − 52.05 dB and a broad effective absorption bandwidth of 7.95 GHz (covering 18–26 GHz). Moreover, the mechanical flexibility and unique microcapacitor-Schottky structure enable efficient surface charge modulation, allowing the direct fabrication of high-performance triboelectric nanogenerators (TENGs). The resulting BMXMo-TENG devices generate an open-circuit voltage of 81.8 V and a power density of 6.4 µW cm⁻², sufficient to drive commercial electronics. Furthermore, an integrated self-powered sensing system is demonstrated for real-time and precise monitoring of various physiological signals, including respiratory rhythms, joint kinematics, and micromotions. This work pioneers a sustainable platform for multifunctional wearables in electromagnetic-heavy environments, unifying high-efficiency EMWA with autonomous biosensing. Graphical
