An S-scheme Ag/CdS/Fe 2 O 3 (Ag/CS/FO) heterojunction was fabricated via a sequential solvothermal and photodeposition method. The microstructure and optoelectronic properties of the synthesized ternary composite were verified by a series of characterization methods. The transfer of photogenerated electron–hole pairs (e − /h + pairs) follows an S-scheme pathway, driven synergistically by the interfacial electric field (IEF) and band bending. That directs electrons (e − ) to the conduction band (CB) of CdS (CS) and holes (h + ) to the valence band (VB) of Fe 2 O 3 (FO), achieving efficient e − /h + pairs separation while maintaining high redox capabilities. Additionally, the incorporated Ag nanoparticles enhance visible-light harvesting via the surface plasmon resonance (SPR) effect and function as electron-transfer bridges, collectively promoting charge migration. Consequently, the composite exhibits high photocatalytic activity, degrading 98.68% of amoxicillin (AMX) under visible light. It also maintains 91.6% efficiency after four cycles, confirming sound stability. Notably, the material demonstrates superior performance in real-life water matrices (tap and river water), highlighting its strong application potential. Graphical abstract

Stretchable bioelectronic hydrogels must reconcile extreme mechanical compliance with stable, high-fidelity charge transport and therapeutic functionality. We introduce a Ag-anchored Ti 3 C 2 T x -polyacrylamide (PAM) hydrogel, in which silver nanoparticles bridge adjacent MXene layers, thereby lowering interlayer resistance and forming a continuous, strain-adaptive conductive network. Concurrent metal-polymer co-ordination with 2D MXene reinforcement yields a hierarchical dissipation architecture featuring ultra-stretchability (∼2036%), high toughness (∼2350 kJ m −3 ), and rapid self-recovery under cyclic loading. Electron-bridge-enabled transport results in stable electro-mechanical sensing (linear Δ R / R o up to 500% strain; R 2 ≈ 0.98) and minimized skin-electrode impedance at 1.5 mm thickness across 1 Hz−10 kHz, outperforming commercial Ag/AgCl electrodes. In human tests, the hydrogel electrodes capture high-fidelity sEMG (SNR ≈ 30 dB) and ECG (SNR ≈ 26.157 dB) with 5-day stability. At the same time, photothermal actuation at 808 nm and 1 W cm −2 rapidly reaches ∼74 ° C and cycles reproducibly, enabling dose-tunable therapeutic heating. The platform also demonstrates >90% fibroblast viability and significant suppression of S. aureus growth. By coupling interlayer electron bridges with dynamic bonding, this work establishes a unified design principle for multifunctional, clinically oriented soft hydrogels that span wearable physiological monitoring and NIR-assisted therapy.

Using plasmonic metal nanoparticles (NPs) represents
an effective
strategy to overcome insufficient visible-light absorption and severe
photogenerated charge recombination in organic photocatalysts via
local surface plasmon resonance (LSPR)-triggered hot-carrier injection
and regulated interfacial charge transport. Herein, plasmonic Ag nanoparticles
(Ag NPs)-decorated 4,5-dibromofluorescein (DBF) nanosheets were readily
prepared through a convenient in situ photodeposition strategy to
construct Ag/DBF nanosheets for photoinduced hydrogen generation under
visible-light. Benefiting from the intrinsic light-harvesting capability
of DBF, together with the combined effects of plasmonic Ag NPs and
interfacial Schottky junction formation, the Ag/DBF nanosheets exhibit
significantly enhanced charge separation and interfacial electron-transfer
efficiency. Under visible-light irradiation, plasmon-induced hot electrons
produced by Ag NPs migrate into the conduction band of DBF, while
the Ag NPs simultaneously function as electron sinks to inhibit charge
carrier recombination and accelerate surface proton reduction. The
optimized 6.0 wt % Ag/DBF nanosheets exhibit a hydrogen evolution
rate of 1265.2 μmol g –1 h –1 , 111-fold higher than that of pristine DBF. It retains robust structural
and photocatalytic stability in multiple cycling runs. This work reveals
the synergistic coupling mechanism between plasmonic hot-electron
transfer and organic semiconductor photocatalysis, offering an effective
strategy to construct high-performance plasmonic organic photoactive
materials for solar-to-hydrogen conversion.

The flexible substrates with high activity are limitedly utilized for the Surface Enhanced Raman Spectroscopy (SERS) detection of Aflatoxin B 1 (AFB 1 ) due to their complex and uncontrollable synthesis. Here, a multistep temperature synthetic strategy is innovatively proposed to facilely and controllably synthesize Ag nanowires loaded on the flexible polyethylene terephthalate nonwoven fabric surface (i.e., Ag NWs@PET). The above strategy can effectively promote the generation and the anisotropic growth of small-sized Ag seeds and thus ensure the uniformity of obtained Ag NWs, providing a valuable reference for the formation of other metal nanowires. Furthermore, Ag NWs@PET is employed as active substrates for the SERS detection of the AFB 1 in corns. Ag NWs@PET exhibits superior sensitivity, mechanical stability, reproducibility, and long-term stability. Noteworthy, by means of Ag NWs@PET, the quantitative detection of AFB 1 ranged from 10 -8 to 10 -13 M can be rapidly achieved. Clearly, as-obtained flexible Ag NWs@PET as a promising SERS substrate can pave the way for the expended implications of the SERS detection in food safety.

Proton-conducting solid oxide fuel cells (H-SOFCs) demonstrate substantial potential for intermediate-to-low temperature operation due to the lower migration activation energy of protons (H + ) compared to oxygen ions (O 2− ). To address the critical role of cathode materials in determining cell performance, this study employs an A-site silver (Ag) doping strategy in perovskite oxide. BaCo 0.4 Fe 0.4 Zr 0.1 Y 0.1 O 3-δ (BCFZY), Ba 0.95 Ag 0.05 Co 0.4 Fe 0.4 Zr 0.1 Y 0.1 O 3-δ (BACFZY) and Ba 0.9 Ag 0.1 Co 0.4 Fe 0.4 Zr 0.1 Y 0.1 O 3-δ (BACFZY-1) materials are all prepared using the sol-gel synthesis method. The investigation into the structure and element distribution of the synthesized materials reveals that BACFZY remains in a pure perovskite phase, with all elements evenly dispersed throughout. Ag-doped BACFZY surpasses BCFZY with greater electrical conductivity and thermal expansion compatibility. Moreover, the incorporation of Ag in BACFZY cathode facilitate the oxygen adsorption, leading to lower impedance and superior output performance with maximum peak power density of 1160 mW cm −2 at 650 °C. Meanwhile, The BACFZY cell maintained stable operation for 100 h. The aforementioned experimental findings indicate that the BACFZY material is a promising cathode for H-SOFC.

Blood species identification is crucial for forensic investigations. Surface-enhanced Raman scattering (SERS) offers promising advantages including rapid detection, non-destructive analysis, and high sensitivity, but faces challenges from direct metal-biomolecule interactions that can cause spectral interference and sample degradation. Here, we present a novel approach using graphene/Ag/Styrene Ethylene Butylene Styrene (SEBS) flexible SERS substrates for rapid and non-destructive blood species determination. The innovative “sandwich” structure features single-layer graphene (0.34 nm) positioned between silver nanoparticles and blood samples, effectively preventing direct metal-blood contact while maintaining the superior SERS enhancement. The flexible substrate demonstrates good performance including high detection sensitivity (the detection sensitivity of 4-Mercaptobenzoic Acid (4-MBA) is 10 −12 M), excellent storage stability (>30 days), and remarkable mechanical durability (>100 folding cycles). We collected 682 SERS spectra from five animal species and employed a convolutional neural network algorithm for classification, achieving the classification performance with 98.54% accuracy, 98.29% precision, and 98.38% recall. The flexible substrate enables rapid analysis and maintains the spectral integrity of archived samples for up to 31 days. This flexible graphene /Ag/SEBS platform has reliable capabilities and offers accurate new means for on-site forensic applications: non-destructive analysis, field portability, rapid results, and high accuracy.

Ordered Ag@Au hybrid nanotube arrays were prepared by a galvanic replacement reaction and subsequently evaluated for their effectiveness as substrates for enhancing the fluorescence of poly(3-hexylthiophene) (P3HT). Ordered AgNWs arrays were assembled using a three-phase interface method, and ordered Ag@Au hybrid nanotube arrays were successfully prepared by a galvanic replacement reaction between a HAuCl 4 solution and ordered AgNWs arrays. The morphology of the ordered silver nanowires (AgNWs) arrays and Ag@Au nanotube arrays, as well as the influence of reaction time on the galvanic replacement reaction, were investigated. The fluorescence and laser-Raman properties of the conjugated polymer P3HT on various ordered Ag@Au nanotubes were analyzed. Gold (Au) particles grow on the surface of AgNWs, the diameter of the nanotubes gradually increases, and the ordered Ag@Au hybrid nanotubes form gradually. The surface plasmon resonance (SPR) peaks of Ag@Au hybrid nanotube arrays redshift and become wider as the reaction proceeds compared to AgNW arrays. The fluorescence properties of P3HT films on various ordered Ag@Au hybrid nanotubes were much higher than those on bare silicon substrates, but compared to the gold nanowire array, there is a decrease. As the galvanic displacement reaction progresses, the degree of reduction in fluorescence intensity increases. The unique aspect of this work was that the plasmon resonance wavelength of the ordered Ag@Au hybrid nanotube arrays showed a substantial redshift and broadening, which is much closer to biological samples. The ordered Ag@Au hybrid nanotube arrays can be used as ultra-sensitive fluorescence sensing platforms.

Surface oxygen vacancies (Vos) in bismuth-based layered photocatalysts are highly active yet prone to deactivation via refilling by ambient oxidants, posing a major stability challenge for their practical application in urban environmental remediation. To address this, Ag nanoparticles were in-situ photodeposited onto Vo-rich Bi 4 Ti 3 O 12 (BTO-Vo) to construct Ag@BTO-Vo- n composites with varied Ag loadings. The optimal catalyst Ag@BTO-Vo-20 displays exceptionally enhanced photocatalytic activity, with both its degradation kinetics and turnover frequency (TOF) reaching levels over 28.5 and 22.7 times higher than those of pristine BTO and BTO-Vo, respectively. This performance improvement originated from optimized charge carrier dynamics, where the synergistic effect of Vos and Ag/BTO-Vo Schottky junction prolonged carrier lifetime by 2.1 times, enhanced photocurrents by 2.7-fold, and reduced interfacial charge-transfer resistance, leading to efficient charge separation. Mechanistic investigations identified superoxide radicals and holes as the primary active species. Crucially, Ag nanoparticles provide effective protection for the surface Vos through interfacial electron modulation and competitive O 2 adsorption, thereby inhibiting their deactivation and ensuring catalyst stability. This was further validated by comparative EPR analysis of H 2 O 2 -filling experiment. This work elucidates a dual stabilization mechanism where Ag crucially prevents the healing of surface Vos, offering a strategic pathway to design durable and highly active layered photocatalysts for efficient purification of urban environmental pollutants.

Developing novel materials to improve the global food supply is vital to combat hunger, achieve food security and promote sustainable agriculture. To address this issue, we employed red-emitting Ag-In-S-Zn (AISZ) quaternary quantum dots (QDs) as light converters to fabricate AISZ QDs-loaded ethylene vinyl acetate (EVA) copolymers (AISZ/EVA) films to improve the light conditions for crop growth. The synthesis of AISZ QDs was optimized to achieve a high quantum yield (73%) and an emission band matching the absorption window of chlorophyll a and b. Using EVA resin as the matrix, efficient ultraviolet-to-red light-converting AISZ/EVA films with varying AISZ content were prepared by the solvent evaporation method. The fluorescence and transmittance of these light-conversion films along with a blank EVA control, were characterized. Subsequent 28-day lettuce cultivation under controlled light illumination revealed that the 1.0 wt.% AISZ/EVA film induced maximal growth enhancement. The fresh weight and dry weight were increased by 28.2% and 34.4%, respectively, while the contents of total chlorophyll, chlorophyll a, chlorophyll b, carotenoid, soluble sugars and proteins were increased by 48.8%, 51.3%, 43.8%, 40.8%, 33.6% and 37.2%, respectively. The results demonstrate that broad-emitting AISZ QDs served as efficient light converters to fabricate agricultural light-conversion films, highlighting their broad application prospects and promising commercial potential in controlled environment agriculture.

Thermal-driven Ag intercalation enables vdW-gaps doping in 3D-printed n-type Bi 2 Te 2.7 Se 0.3 . • vdW-gaps Ag enhances electrical transport and lowers lattice thermal conductivity. • Peak ZT of 1.26 and module efficiency of 6.0% are achieved. Bi 2 Te 3 -based materials are recognized as the benchmark thermoelectrics for near-room-temperature applications. However, substantially inferior thermoelectric performance in n-type Bi 2 Te 3 compared to highly performance p-type variants creates a critical performance asymmetry, restricting energy conversion efficiency. Herein, we develop thermal-driven Ag intercalation into van der Waals (vdW) gaps of 3D-printed n-type Bi 2 Te 2.7 Se 0.3 (BTS), achieving vdW-gaps doping. The first-principles calculations demonstrate that interstitial Ag atoms are mainly located at the vdW gaps, which reduces their direct perturbation to the conductive layers. As a result, they provide spatially separated conduction electrons, increasing carrier concentration while sustaining high carrier mobility. Furthermore, the Ag-intercalation-induced superlattice structures efficiently scatter mid-to-long wavelength phonons, thereby effectively suppressing lattice thermal conductivity. Ultimately, the BTS + 0.2% Ag intercalated sample achieves a peak ZT of 1.26 at 375 K, with an average ZT ∼1.12 maintained across the operational temperature range of 300-500 K. Leveraging such exceptional thermoelectric performance, a thermoelectric module assembled with 127 pairs legs delivers a conversion efficiency of 6.0% under ΔT = 180 K. This work provides a facile thermal-driven Ag intercalation strategy for vdW-gaps doping of n-type Bi 2 Te 3 -based thermoelectrics, breaking the performance asymmetry bottleneck and enabling high-efficiency near-room-temperature thermoelectric modules.

Photocatalytic amine oxidation coupled with hydrogen evolution offers a sustainable route to green hydrogen and value-added chemicals, yet efficient N–H bond activation remains challenging. Herein, we construct atomic Ag–N frustrated Lewis pairs (FLPs) composed of low-valence Ag single atoms as Lewis acids and adjacent electron-rich N atoms as Lewis bases by anchoring high-density Ag single atoms onto N-deficient g-C 3 N 4 nanosheets to form an Ag–N 1 C 2 structure. These atomic Ag–N FLP sites enable efficient adsorption and selective N–H bond cleavage through synergistic coordination of Ag with the amine N atom and neighboring N sites with H. Meanwhile, Ag single atoms serve as effective hole-transfer bridges, enhancing surface hole accumulation and accelerating oxidation kinetics. The resulting photocatalyst exhibits a benzylamine oxidation rate of 0.85 mmol g cat −1 h −1 , converts benzylamine to N -benzylidenebenzylamine with >99% selectivity, and achieves a hydrogen evolution rate of 1.86 mmol g cat −1 h −1 .
