Developing an effective analytical method for microtrace detection of ancient silk is highly desirable and vitally crucial for exploring the origin and spread of silk. Herein, a taxonomically specific anti-fibroin monoclonal antibody was prepared and an elaborate visible/near-infrared (vis/NIR) photoelectrochemical (PEC) immunosensor was proposed. The sensor employed Ag2S nanoparticles (NPs) grown in situ on ZnO nanowire array-MXene nanocomposites (ZnO-MX) via a sonochemical method as a photosensitive material. The experimental results illustrated that the ZnO-MX/Ag2S-based sensor presented 6.8 times larger PEC responses than a ZnO-MX-based sensor under visible light illumination, and the PEC signal of the ZnO-MX/Ag2S nanocomposites was 30 times as high as that of ZnO-MX under 808 nm NIR light, indicating enhanced photoelectric activity and a matched energy band structure of ZnO with MXene and Ag2S. This PEC immunosensor exhibited excellent potential for the ultrasensitive detection of Bombyx mori silk traces due to its wide linear range of 0.005–50 ng mL–1 and low detection limit of 1.51 pg mL–1. Additionally, the immunosensor showed outstanding specificity, stability, and repeatability, particularly for qualitative detection of archeological artifacts. Given ots aforementioned benefits, ZnO-MX/Ag2S nanocomposites are potentially attractive photoactive materials for use in vis/NIR light-driven PEC immunosensors. Moreover, this demonstrated method offers a feasible method to investigate the history and distribution of ancient silk. © 2023, The Authors. All rights reserved.

This paper presents the effect of interlaminar shear property on the ballistic response of ultra-high molecular weight polyethylene (UHMWPE) fiber composite laminate and discusses the detailed progressive ballistic damage process. Specifically, two kinds of UHMWPE fiber composite laminates with different interlaminar shear strength (ILSS) are impacted by a standard projectile (7.62 mm × 39 mm), and their multi-scale internal damage morphologies are characterized. Based on damage patterns, an evaluation model of laminate energy absorption is established to analyze the dissipation mechanism of the kinetic energy of the projectile. Results of ballistic tests indicate that the reduction of ILSS may result in the degradation of anti-penetration performance and in more serious internal damage. Internal damage morphologies show that shear fracture and delamination fracture are the primary failure modes during ballistic impact. The energy absorption by the laminate via tensile deformation, delamination failure and shear failure may account for 56.21%, 17.45%, and 16.49% of the projectile kinetic energy, respectively. Hence, tensile deformation may be the primary energy dissipation mechanism of projectile kinetic energy. © 2022

As a kind of battery that can work normally under deformation, flexible batteries are widely applied in wearable, portable and biomedical devices. However, the development and large-scale production of flexible batteries are restricted with the balance between the flexibility requirements and conductivity of the cathode. Modifying carbon-based materials used in cathodes is an effective means to address the poor electrochemical performance of flexible batteries. In this review, an extensive generalization about the preparation methods of cathode based on carbon materials including doping conductive materials, surface structure treatment, electrode macro-structure control, regulation of chemical properties, multilayer composite and treatment of carbon-based material precursors is enumerated. In addition, the modification of carbon-based materials in different types of batteries (zinc battery, lithium battery, supercapacitor, sodium battery and others) and batteries with different structures (1D, 2D and 3D) has been analyzed in detail. Finally, we have summarized the outlook section to provide some insights into the future prospects of cathode materials in flexible batteries. These discussions will offer more directions for the practical application of flexible batteries with superior electrochemical performance. © 2025

Photo-stimulated luminescent materials are one of the most attractive alternatives for next-generation optical information storage technologies. However, there are still some challenges in regulating appropriate energy levels in luminescent materials for optical information storage. Herein, a green emission nanophosphor Zn2SiO4: Cr3+, Mn2+ with the trap depth of 1.05 eV, fulfilling the requirements for optical information storage, was fabricated for the first time through the solution combustion method and subsequent heat treatment at 1000℃ for 2h. The crystal structure, micromorphology, photoluminescence (PL), photoluminescence excitation (PLE), and afterglow properties of Zn2SiO4: xCr3+, yMn2+ were studied systematically. By applying the strategy of trap depth engineering, high trap density with proper trap depth was observed when Cr3+ ions were introduced into Zn2SiO4: Mn2+. Thermoluminescence (TL) glow-curve analysis through the initial rise (IR) method was conducted to gain some insight into the information of traps. As proof of application, information storage was experimentally achieved by choosing 275 nm illumination for "information writing" and 980 nm NIR excitation for "information reading". The results indicate that Zn2SiO4: Cr3+, Mn2+ phosphor holds promise for potential applications in the field of optical information storage. Copyright © 2024, The Authors. All rights reserved.

In this paper, efficient, economical and environmentally friendly mesoporous silica microspheres (MSMs) were prepared for the first time by reversed-phase suspension-dispersion method using water glass and acetic acid as raw materials. MSMs had excellent sphericity, with particle size concentrated at 100 µm, specific surface area of 207.90 m2/g and pore volume of 0.4743 cm3/g. Adsorption equilibrium of Ga(III) by MSMs was reached in 30 min on 30 ppm GaCl3 with dosage of 2 g/L and pH=3, conforming to the pseudo-second-order kinetic model. The adsorption isotherm showed that the adsorption of Ga(III) by MSMs is endothermic process with saturation adsorption of 71.97 mg/g at 318 K. The Kd of MSMs for Ga(III) was above 8000 in three multivariate systems of zinc ore leaching residues, fly ash and e-waste, showing excellent selectivity. The desorption equilibrium of 78.44% was reached at 2 mol/L H2SO4 for 120 min, and the adsorption rate of Ga(III) on MSMs was still exceeded 90% after five adsorption-desorption cycles, showing that MSMs have excellent cycling performance. The fixed-bed column experiments showed the efficient separation and enrichment performance of MSMs for Ga(III) in simulated leachate. The adsorption process in MSMs is synergistic interaction is between physical adsorption and ion-exchange, with ion-exchange being the main mechanism. This provides a new approach to address the issues of poor adsorption capacity and slow adsorption-desorption rate faced by adsorbents for the highly selective recover of Ga(III) from zinc ore leaching residues, fly ash and e-waste, which is potentially promising for application. © 2025, The Authors.
