To address the challenges of personal thermoregulation, this study proposes a multi-modal thermal management strategy based on a three-dimensional (3D) spacer Janus fabric (F-M/A-JF) asymmetrically decorated with MXene and silver. By leveraging the 3D structure's static air-trapping and MXene's low mid-infrared emissivity (0.419), the system achieves a 5.6 °C increase in simulated skin temperature indoors without energy consumption. Under simulated sunlight (100 mW cm −2 ), the Janus design exhibits a differential response—reaching 79.8 °C on the MXene side versus 62.9 °C on the Ag side—providing an “adaptive mode” to prevent outdoor overheating. Owing to the high electrical conductivity of MXene, the fabric achieves a surface temperature of 137.3 °C at a low voltage of only 5 V and demonstrates a high electromagnetic interference (EMI) shielding effectiveness of up to 57 dB. The “MXene Guardian” strategy ensures functional longevity over 20 washing cycles and 95.3% self-cleaning efficiency while preserving 93.8% of the original moisture permeability (5.14 mg cm −2 h −1 ). This robust system offers an energy-saving design paradigm for next-generation smart textiles in dynamic environments.

Transitioning to a net-zero society requires efficient electrochemical technologies for converting carbon dioxide (CO 2 ) into valuable products powered by renewable energy. The commercial deployment of CO 2 electrolyzers requires catalysts that combine high activity, selectivity, and scalability. This study reports a novel and facile synthesis strategy for highly loaded, uniformly dispersed silver nanoparticles (AgNPs) on conductive carbon substrates using 1-dodecanethiol as a stabilizing ligand. This approach enables simultaneous control over particle size (<7 nm) and metal loading (up to 60 wt %) on Vulcan XC (low surface area) and Ketjen Black (high surface area). Using 1-dodecanethiol effectively prevents agglomeration, yielding highly dispersed AgNPs even at ultrahigh loading. We present a systematic investigation into the influence of carbon support surface area on Ag dispersion, loading efficiency, and electrocatalytic performance. Notably, Ag/KB-60 exhibits a faradaic efficiency of 90 % for CO at −0.81 V vs. RHE and remarkable operational stability over 24 h. This work presents a low-cost, thiol-based synthesis strategy that is readily scalable for industrial manufacturing of CO 2 electrolyzers, enabling the production of high-performance Ag/C catalysts with commercial relevance.

Plasmonic nanoparticles (NPs) enable exceptional light harvesting via localized surface plasmon resonances (LSPR), yet their photocatalytic utility is limited by ultrafast charge recombination and surface contamination from synthesis. Here, we overcome these challenges by applying the surface chemistry of silicon nanocrystals (SiNCs) to synthesize hybrid nanostructures of uncoated silver nanoparticles (AgNPs). The alkyl-passivated SiNC surface acts as a reductive template, guiding the in-situ formation of clean, interfacially coupled AgNPs while protecting the SiNC core from oxidation. This tailored architecture leverages a synegiestic mechanism to enhance AgNP plasmon resonance, drive efficient hot-electron transfer and improve charge carrier separation. The resulting Ag@SiNC hybrid achieves improved CO 2 reduction performance, with a CO yield of 1,552 μmol/g and near 100% selectivity under visible light irradiation. This work establishes surface-engineered SiNCs as a versatile platform for designing high-performance plasmonic–semiconductor photocatalysts.

Conventional synthetic routes to Ag nanocubes (AgNCs) often leave reagent residues on the particle surface, thereby compromising analyte accessibility and surface-enhanced Raman scattering (SERS) sensitivity. Here, AgNCs were grown in-situ on two-dimensional (2D) nanocellulose films via a photo-induced reduction process, yielding surfactant-free particles with tunable morphology. No additional reducing agents or surfactants were introduced during synthesis, reducing surfactant-derived surface coverage and improving the accessibility of the resulting AgNCs. Notably, the dissolved oxygen in the reaction solution played an important etching role in eliminating the twins during the nucleation process and generating AgNCs with a single crystal structure. The nanocellulose film served both as a photo-reactive substrate, where surface hydroxyl groups acted as reductive sites for the photo-induced conversion of Ag(I) to Ag(0), and as a 2D support that stabilized interfacial nucleation and growth. In addition, the in-situ synthesized AgNCs were uniformly distributed across the nanocellulose film surface, enabling one-step fabrication of flexible SERS substrates under mild conditions. The optimized substrate enabled highly sensitive detection of Rhodamine 6G (R6G), with a limit of detection of 6.24 × 10 −12 g L −1 , approximately fivefold lower than that of the same substrate after surfactant adsorption. This strategy provides a simple platform for constructing nanocellulose-based SERS substrates for trace detection.

Hydrated vanadium pentoxide (VOH) is regarded as a promising cathode material for aqueous zinc-ion batteries (AZIBs) owing to its open layered framework and multivalent redox chemistry. However, its practical application is limited by sluggish charge-transfer kinetics and structural instability during repeated Zn²⁺/H⁺ insertion and extraction. Herein, an integrated AgNP@MX-VOH composite cathode is constructed by coupling VOH nanorods with Ag nanoparticle-decorated Ti₃C₂Tₓ MXene. The flexible MXene sheets provide continuous electron-transport pathways and bridge neighboring VOH nanostructures, while the dispersed AgNPs act as local conductive contact nodes and regulate the stacking configuration of the MXene assembly. This hierarchical interfacial network helps suppress MXene restacking, maintain accessible porous regions, and improve the structural and electrical stability of the conductive framework. Meanwhile, the formation of the AgNP@MX-VOH heterointerface modifies the local electronic environment of VOH, accompanied by an increased V⁴⁺ contribution and enhanced oxygen-defect-related features.These structural and interfacial effects facilitate charge transfer and reversible ion-storage kinetics while maintaining electrode integrity during cycling. Consequently, the AgNP@MX-VOH cathode delivers a high reversible capacity of 361.2 mAh g⁻¹ at 0.5 A g⁻¹ , a capacity of 268.96 mAh g⁻¹ at 5 A g⁻¹ , and 90.2% capacity retention after 1000 cycles at 5 A g⁻¹ . This work provides an interfacial-engineering strategy for constructing stable MXene/vanadium-oxide heterostructures toward durable aqueous zinc-ion storage.

As industrial waste gas, nitrogen dioxide (NO2) is a serious hazard to air pollution and human health, and there is a pressing demand for developing high-performance NO2gas sensors. Tin disulfide (SnS2), a representative two-dimensional metal sulfide characterized by a significant specific surface area, a suitable electron band gap, and an easily tunable layered structure, shows a broad application prospect in gas sensing applications. Nevertheless, SnS2-based gas sensors suffer from poor sensitivity, which seriously hinders their application in room temperature gas sensing. In this study, Ag/SnS2heterojunction nanomaterials were synthesized by an in situ reduction approach. The findings reveals that the gas-sensitive response of the Ag/SnS2nanocomposites at room temperature under visible light irradiation can achieve 10.5 to 1 ppm NO2, with a detection limit as low as 200 ppb, which realizes the room-temperature detection of Sub-ppm NO2. Meanwhile, the sensor exhibits good selectivity, reproducibility (cyclic stability > 95%). The improved gas sensitivity of the Ag/SnS2sensor can be due to the synergistic effect of the carrier separation at the Ag/SnS2Schottky junction and the localized surface plasmon resonance (LSPR) of Ag nanoparticles. The LSPR effect significantly enhances light absorption and surface-active site density, facilitating trace NO2detection at room temperature. This study provides the foundation for the subsequent development of room temperature layered metal sulfide gas sensors.

A flexible silver triangular nanoplate (Ag TNPs)@m-phenylenediamine (mPD)@polyacrylonitrile (PAN) skin patch based on electrospinning is fabricated and applied to detect human beta-defensin 2 (HBD-2) by using surface-enhanced Raman scattering (SERS). First, PAN was used as the base material to create a fibrous membrane through electrospinning. The fibers were then modified with Ag TNPs by mPD endowing positive charges, forming a flexible Ag TNPs@mPD@PAN substrate. The flexible substrate features advantages of simple preparation, low cost, and convenient portability, which are suitable for in situ rapid detection on irregular surfaces. The combination of the flexible Ag TNPs@mPD@PAN substrate with Ag TNPs probes enabled the specific detection of HBD-2. It demonstrated satisfactory sensitivity and reproducibility with a wide detection range of 100–10 ng/mL and a limit of detection (LOD) of 59.57 fg/mL. Eventually, the flexible substrate was applied to HBD-2 detection on the surface of contaminated chicken skin. This study provides a simple and highly sensitive method for the detection of HBD-2, offering a novel approach for the non-invasive rapid diagnosis of psoriasis and the monitoring of disease progression.

Polymer dielectrics are essential materials for next − generation power systems. However, they suffer from low energy density and poor breakdown performance at high temperatures, which restricts their application in high-temperature fields. The BaTiO 3 /Al 2 O 3 /Ag nanofibers (BT/AO/Ag NFs) were fabricated via electrospinning as nanofillers to boost the high-temperature energy storage of polyetherimide (PEI) composites. Experiments and finite electric field simulations demonstrate that combining high permittivity BaTiO 3 , highly insulating Al 2 O 3 , and metallic Ag improves the dielectric permittivity and breakdown strength of PEI composites at high temperatures. Remarkably, the composite film incorporating merely 0.3 wt% BT/AO/Ag NFs achieves an ultra − high energy density of 9.047 J cm −3 at 200 ℃, representing a 147 % enhancement compared to pure PEI and surpassing most polymer composites filled with alternative nanofillers. Furthermore, this composite exhibits outstanding charge–discharge cycling stability (>100,000 cycles at 200 MV m −1 ) and superior power density (>1.145 MW cm −3 ) at 200 ℃, positioning it as an ideal candidate for high-temperature capacitor applications. The work indicates that this nanofiber architectural design not only provides an effective strategy for developing high-temperature dielectric composites, but also shows great potential in next − generation dielectric capacitors.

Synthesizing value-added solar fuels represents a promising solution to address energy and environmental issues. Its efficiency is determined by the performance of photocatalysts, and the main challenges lie in achieving efficient interfacial charge transfer and utilization, which are highly related to the assembly of cocatalysts. Herein, we design La 3+ -defect LaFeO 3 nanofibers with a higher specific surface area to achieve highly dispersed loading of Ag nanoparticles through a one-step coaxial electrospinning technique. Characterizations and theoretical calculations revealed that La 3+ defects favor the anchoring of Ag nanoparticles and the formation of a Schottky junction, thereby facilitating the interfacial charge separation and transfer. Additionally, this synergistic engineering efficiently boosts CO 2 adsorption/activation and strengthens the proton affinity, preferentially driving the multi-electron reduction. Owing to these benefits, the optimized nanofibrous Ag/La 0.9 FeO 3 sample exhibits promising photothermal catalytic performance, yielding CH 3 OH of 7.12 μmol·g -1 ·h -1 , which is 2.8-fold over pristine LaFeO 3 , along with good stability and selectivity. This work highlights the effect of interfacial construction on developing advanced photocatalysts.

The environmental pollution resulting from organic dye wastewater presents a significant threat to human health. Photocatalysis has emerged as a highly promising approach for mitigating wastewater contamination. In this study, a novel synthetic strategy was developed using NH 2 -UiO-66 as a template. By precisely controlling the amount of Ag + ions introduced into the NH 2 -UiO-66 precursor and employing a straightforward reduction approach, the Ag-NH 2 -UiO-66 composite photocatalyst was successfully synthesized. Comprehensive characterization via X-ray diffraction (XRD), scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), transmission electron microscopy (TEM), and X-ray photoelectron microscopy (XPS) confirmed that the incorporated Ag+ ions were effectively reduced to metallic silver and uniformly dispersed within the porous framework. Photocatalytic degradation experiments employing Rhodamine B (RhB) as a model pollutant under ultraviolet irradiation demonstrated that the catalyst with a silver loading of 0.05 mol/L achieved a maximum degradation efficiency of 91% within 150 min, markedly surpassing the 39% efficiency exhibited by pristine NH 2 -UiO-66. Furthermore, cyclic stability tests verified the catalyst's excellent reusability and structural durability. Mechanistic investigations revealed that superoxide radicals (O 2 − ) served as the predominant reactive species responsible for RhB degradation in the Ag-NH 2 -UiO-66 system. This work presents a simple and effective strategy for fabricating highly efficient and stable MOF-based photocatalysts for the remediation of dye-contaminated wastewater.

In this contribution, the efficiencies of perovskite solar cells have been further enhanced, based on optical optimization studies. The photovoltaic devices with textured perovskite film can be obtained and a power conversion efficiency (PCE) of the textured fluorine-doped tin oxide (FTO)/Ag nanoparticles (NPs) embedded in c-TiO2/m-TiO2/CH3NH3PbI3/Spiro-OMeTAD/Au showed 33.7% enhancement, and a maximum of up to 14.01% was achieved. The efficiency enhancement can be attributed to the light trapping effect caused by the textured FTO and the incorporated Ag NPs, which can enhance scattering to extend the optical pathway in the photoactive layer of the solar cell. Interestingly, aside from enhanced light absorption, the charge transport characteristics of the devices can be improved by optimizing Ag NPs loading levels, which is due to the localized surface plasmon resonance (LSPR) from the incorporated Ag NPs. This light trapping strategy helps to provide an appropriated management for optical optimization of perovskite solar cells.

In this paper, we reported a facile and effective approach for fabrication of SiO 2 –CoFe 2 O 4 supported dispersed Ag nanoparticles (NPs). The as-synthesized nanocomposites (NCs) were characterized by XRD , TEM, EDX, ICP , XPS and N 2 adsorption-desorption, and used as catalyst for H 2 production from hydrolysis of ammonia borane (AB). A poorly active catalyst of Ag NPs was dramatically converted into a highly active catalyst, in the presence of inactive SiO 2 –CoFe 2 O 4 support. Among all the Ag(0)/SiO 2 –CoFe 2 O 4 NCs catalysts tested, the Ag loading of 0.98 wt% exhibited the highest catalytic activity toward hydrolysis of AB with a highly turnover frequency of TOF = 264 min −1 at room temperature, being higher than that of most reported Ag-based catalysts. Especially, these catalysts can be readily separated from the solution for recycle purpose, and can keep the high activity even after seven times of recycle. These results showed that Ag(0)/SiO 2 –CoFe 2 O 4 NCs prepared in this study are a promising catalyst for hydrogen production from aqueous AB and for developing a highly efficient hydrogen storage system for fuel cell applications .
