Electronic textile is a promising platform for next-generation wearable systems, where transparent conductive fibers are essential building blocks for optoelectronic functions. Current transparent conductive fibers are typically realized by coating conductive nanomaterials onto a polymer fiber substrate. However, this strategy generally suffers from weak interfacial adhesion and thus causes conductivity degradation under mechanical deformations or environmental exposure. In this work, we report a high-performance transparent conductive fiber based on disulfide-functionalized thermoplastic polyurethane. Silver nanowires (AgNWs) react with sulfur atoms in the disulfide groups to form robust Ag-S covalent linkages, thereby stabilizing the AgNWs network. The resulting fibers exhibit a balanced combination of high conductivity (2.7 × 10 3 S/m) and optical transmittance (81%). Their conductivity and optical transmittance can be tuned by adjusting the AgNWs loading, while maintaining high transparency and superior mechanical durability under harsh conditions, including 1000 cycles of bending, twisting, and abrasion. We further integrate these fibers into electroluminescent fibers and display textiles through wrapping or weaving. These devices exhibit high brightness, uniform emission, and long-term operational stability. This interfacial engineering strategy improves compatibility between conductive networks and flexible polymers, enabling high-performance electronic fibers and textiles.

Spinel ferrites with a general formula of AFe 2 O 4 (A=Zn, Mn, Ni, or Co) have attracted considerable attention in chemiresistive gas sensors, given their superior chemical stability and good catalytic activity. However, the development of spinel ferrite-based gas sensors that simultaneously possess high selectivity and excellent humidity resistance has so far remained challenging. Herein, we successfully fabricated a novel CoFe 2 O 4 /WO 3 /Ag (CWA) composite by depositing the WO 3 nanosheets and Ag nanoparticles successively onto the porous CoFe 2 O 4 (CFO) nanosheets that were obtained through co-precipitation, calcination, and in-situ reduction methods. Due to the unique porous layered structures of the CFO nanosheets, the formation of p-n heterojunctions between the CFO and WO 3 nanosheets, and the catalytic effects of the Ag nanoparticles, the CWA composite-based gas sensor exhibited distinct selectivity (at least 4 times enhanced sensitivity), wide detection range (0.1∼500 ppm) reproducibility (RSD=1.3% in 5 independent batches), stability (maximum 4.4% fluctuation over 56 days), and humidity resistance (>60.7% response retention at 90% RH) towards triethylamine (TEA). Density functional theory (DFT) calculations further proved the intense TEA chemisorption on the Fe sites and the indispensable role of Ag in electron mobility modulation. In addition, a practical gas-sensing system was also developed to demonstrate its real-world implementation. This study provided a general strategy for constructing spinel ferrite-based gas sensors that could work in high-humidity environments.

In this paper, Au-Ag alloy nanostar (Au-Ag NSt) substrates were prepared by liquid–liquid three-phase self-assembly method, and the influence of preparation conditions on their Raman activity of the substrate was explored. By adjusting the gold-silver ratios of alloy seeds and the concentration of AgNO 3 in the growth solution, it was found that the LSPR peak can be adjusted. Under the conditions of Au 1 -Ag 3 nanoparticles as seeds and 200 μL AgNO 3 solution (2 mM) as epitaxial growth solution, the prepared Au 1 -Ag 3 NSt substrate exhibits excellent SERS activity. The substrate can detect R6G and CV probe molecules with detection limits as low as 10 −11 M and 10 −10 M, respectively. Experiments have confirmed that the substrate has the characteristics of high sensitivity, good uniformity and strong stability. In addition, the substrate can detect APM molecules far below the safety standard, which further proves that the structure has excellent practical application potential as a SERS substrate.

Bi 5 O 7 I was considered as a promising photocatalyst due to its unique structure. However, the recombination rate of electron–hole pairs generated by Bi 5 O 7 I is too fast, making it impossible for practical applications. In this study, Bi 5 O 7 I catalysts deposited with various amount of silver were manufactured and their photocatalytic efficiency for rhodamine B (RhB) was measured. It was found that Bi 5 O 7 I with a silver deposition of 15% (named as Bi 5 O 7 I/Ag-15) exhibits the highest catalytic performance, with a degradation rate of 97.34% for RhB after illumination for 90 min. The cyclic test results confirmed that Bi 5 O 7 I/Ag-15 still maintained high photocatalytic activity after six cycles of degradation. In addition, Bi 5 O 7 I/Ag-15 also exhibits an excellent photocatalytic performance in acidic or alkaline environments, indicating its potential for practical applications. A reasonable degradation mechanism for RhB photocatalysis was then proposed. Graphical abstract

N2O/CO2 separation in the tail gas of adipic acid presents a significant challenge due to the closely resembling physical characteristics exhibited by CO2 and N2O. Herein, adsorption and separation performances of CO2 and N2O on FAU-type zeolite Y with different cations (Na+ and Ag+) were studied comprehensively. After Ag+ exchange, zeolite Y changes from a CO2-selective adsorbent to a N2O-selective adsorbent. AgY shows high N2O uptake (95.7 cm3/g) but relatively low adsorption heat (23.1 kJ/mol), making it suitable for N2O/CO2 separation. In situ Fourier transform infrared spectrometry indicates that N2O is successfully adsorbed on AgY. The breakthrough experiment reveals that AgY exhibits superior performance in the separation of N2O/CO2 at a flow rate of 20 mL/min while also exhibiting a favorable retention time and ratio of retention time with CO2 breakthrough time, which can reach up to 4.1 min and 0.24, respectively, which makes it an optimum N2O/CO2 separation material reported so far.

The use of InGaN/GaN blue light chips to excite surface-coated yellow phosphors is one of the common strategies for the preparation of WLEDs. In this study, a series (Y,Gd) 3 Al 5 O 12 ((Y,Gd)AG) phosphors doped with different concentrations of Ce 3+ were prepared using the co-precipitation method. The yellow light emission intensity of the phosphor reaches its maximum at a Ce 3+ concentration of 5 %. This observation is consistent with theoretically quenching concentration (4.7 %) calculated by the Stern - Volmer formula and the optimal quantum yield (69.18 %). Further research indicates that the emission efficiency of the sample remains almost same after 7 days and maintained room temperature efficiency of 67 % at 400 K, with a color temperature value of 2662 K and a CRI value superior to that of YAG:Ce. The results TR-PL tests showed that when the concentration of Ce 3+ doping was gradually increased up 5 %, the distance between the emission centers becomes shorter, which leads to a decrease in the emission lifetime and thereby improves the luminous efficiency. When the concentration exceeds 5 %, concentration quenching leads to an increase in non-radiative processes, and this quenching mechanism is identified as energy transfer between Ce 3+ - Ce 3+ ions. This result provides ideas for obtaining highly efficient yellow phosphors, and also provides a realization path for improving the performance of CCTs and CRIs in WLEDs.

In this study, we successfully prepared silver electrodes through a silver mirror reaction. By carefully regulating the amount of ammonia complexing agent in the silver–ammonia solution, we effectively suppressed the decomposition of the plating solution while reducing the surface roughness of silver films from 9.22 nm to 4.42 nm. The electrical conductivity of our solution-processed silver layers was nearly one order of magnitude higher than that of conventional inkjet-printed silver electrodes. When applied as source-drain electrodes in organic field-effect transistors (OFETs), these electrodes enabled devices with an average mobility of 0.13 cm 2 /(V·s) and remarkably low mobility variation of only 8.7%. Furthermore, we modified the silver electrodes through chemical platinum plating, achieving a significant 0.74 eV alteration in work function, which demonstrates the great potential of chemical plating for surface functionalization in solution-processed organic electronic devices.

Electrochemical determination of luteolin is vital to food industry owing to its bioactive properties such as anti-viral, anti-ulcer. However, bare electrode of traditional electrochemical sensors generally have narrow linear range and low sensitivity, which sets limit on their practical application. Accordingly, a new nano-architecture fabricated with Ag doped CoNi-bimetal metal–organic frameworks (Ag-CoNi-MOF) is developed as a material for electrochemical determination of luteolin. The introduction of Ag to three-dimensional (3D) flower-like hierarchical structure greatly increases specific surface area and electrical conductivity, which subsequently provides more excellent active sites for luteolin oxidation. Under optimal conditions, Ag-CoNi-MOF sensor presents a broader linear response to luteolin concentration of 0.002 – 1.0 μM with the detection limit as low as 0.4 nM (S/N = 3). Ag-CoNi-MOF has good anti-interference according to compared amperometric current response of luteolin within different organic analytes and metal ions. Finally, the sensor platform is implemented directly to determine luteolin in human urine for evaluation of its practical application. In general, Ag-CoNi-MOF sensors fabricated perform larger linear range with high sensitivity and anti-interference properties, which can be used as a potential material for electrochemical determination of luteolin.

A facile strategy has been reported to obtain on-line fresh Ag as surface-enhanced Raman scattering (SERS) active substrates by making AgCl nanoparticles exposed to the laser beam of Raman spectrometer. The composition and morphology of AgCl nanoparticles were characterized by X-ray diffraction (XRD), UV–visible (UV–vis) spectroscopy and scanning electron microscopy (SEM). The laser-driven evolvement and possible formation mechanism of cubic AgCl nanoparticles to Ag/AgCl composites were also investigated by transmission electron microscopy (TEM), energy dispersive X-ray spectroscopy (EDS) and high-resolution transmission electron microscopy (HRTEM). Raman measurements demonstrate that the fresh Ag nanoparticles with a few defects have a prominent SERS sensitivity to probe molecules, such as the 4-mercaptopyridine (4-Mpy) and 4-aminothiophenol (PATP) molecules. The SERS intensity of 4-Mpy and PATP increases up to the maximum when the laser irradiation time is prolonged to 50 s, which corresponds to the defect extent and the proportion of fresh Ag in the Ag/AgCl composites. This work provides a simple, efficient and feasible approach for obtaining on-line fresh Ag as SERS substrates.

Eggshell membrane (ESM) has a unique three-dimensional (3D) interwoven fibrous structure and can provide a unique supporting platform for functional nanoparticles . This work reports a novel strategy for fabricating photothermal conversion hybrid membranes by loading boron nitride (BN) and noble metal nanoparticles (Au or Ag) on the 3D network structured eggshell membrane. This hybrid bio-membrane combines the localized surface plasmonization resonance (LSPR) effects of Au (Ag) and the high thermal conductivity of BN, which led to the hybrid bio-membrane responsive to simulated sunlight irradiation and substantially enhanced photothermal conversion effect. The optimal hybrid bio-membrane achieved a high temperature of 88.3 ℃ after irradiation for 100 s under simulated sunlight. This work provides a strategy for designing advanced photothermal conversion materials for drug release and photothermal therapy applications.

A novel cellulose-based colorimetric sensor (DAC-Tu) with N, S sites for Ag + was prepared. The DAC-Tu exhibited excellent selectivity and sensitivity for Ag + with a naked eyes color change from white to black in mixed metal ions aqueous solutions. The naked-eye in-situ detection limit of DAC-Tu for Ag + was 10 −6 mol/L within 10 min. The cellulose matrix and the grafted functional groups ( C S, NH 2 ) of DAC-Tu all contributed to the low naked-eye in-situ detection limit. The mechanism of the visual recognition of DAC-Tu sensor for Ag + was proposed, the N and S atoms of DAC-Tu preferentially coordination chelated with Ag + to form N Ag, S Ag, and Ag 2 S, and enriched on the cellulose matrix, thus the DAC-Tu presented different color change in response to different concentrations of Ag + . The as-prepared DAC-Tu colorimetric sensor showed a great application prospect for in-situ naked eyes detection of Ag + .
