Conventional electromagnetic interference (EMI) shielding materials predominantly reflect waves, causing secondary pollution, while achieving absorption-dominated shielding without complex structures or magnetic components remains a significant challenge. Inspired by the scrub sponge architecture, this study develops a CNTs/MF-PA foam-film composites with modular bi-conductive networks for tunable absorption-dominated EMI shielding, where the porous foam serves as a regulatory component that modulates the electromagnetic response of the underlying organic coating. The asymmetric design, combining a carbon nanotube-loaded melamine foam (CNTs/MF) with a replaceable silver nanowire-based organic coating (PA), achieves 76.89 dB shielding effectiveness (SE) and 0.94 absorption coefficient (A) without magnetic components. Notably, by interchanging the bottom coating with varying EMI SE (20–80 dB), the overall shielding performance can be precisely tuned while maintaining an ultra-high A above 0.93, demonstrating universal foam regulation of different coatings for customizable shielding. The superior performance stems from synergistic effects where the foam layer ensures excellent impedance matching, promotes multiple scattering, and induces phase cancellation through extended propagation paths, while the organic coating provides robust shielding. This work offers a groundbreaking strategy for developing functional organic coating materials with tailored electromagnetic performance, holding immense promise for applications in flexible electronics and advanced aerospace systems.

The use of photogenerated carriers to regulate interfacial photo-redox reactions and improve the efficiency of photocatalytic applications has become a hot topic in photocatalyst research. We proposed a novel strategy, which enables efficient charge separation by uniformly deposition CuS/Bi₂S₃ nanoparticles on three-dimensional porous cellulose-derived carbon aerogel (CA), and utilizes highly active holes excited by ultraviolet-visible light to drive surface reactions, demonstrating excellent performance in the photo-oxidative degradation of methylene blue (MB) organic pollutants. The samples were characterized and structurally tested using techniques such as X-ray fluorescence spectroscopy, X-ray diffraction analysis, scanning electron microscopy, and a BET specific surface area analyzer. Under visible light irradiation, the composite material demonstrated remarkable degradation efficiency for methylene blue, achieving 98.98% removal within 80 min while maintaining over 87.48% of its initial activity after five consecutive reaction cycles. The enhanced photocatalytic performance is attributed to the fact that the carbon aerogel matrix provides a 3D framework with high surface area to effectively disperse catalyst nanoparticles and organic dye molecules near the active site, its conductive network facilitates efficient electron transport, and the porous structure can optimally separate photogenerated electron-hole pairs by enhancing light absorption through internal scattering mechanisms. We identified that superoxide anions (·O₂ − ) and hydroxyl radicals (·OH) act as the primary active species in the degradation process through radical trapping experiments. This study not only presents a high-performance, environmentally friendly catalyst for wastewater treatment but also offers valuable design principles for developing biomass carbon-based photocatalytic systems with S-scheme heterojunctions.

Due to their exceptional power density and fast charge–discharge performance, dielectric ceramic capacitors have emerged as vital components in advanced pulsed power systems. However, concurrently achieving excellent recoverable energy density (Wrec) and high efficiency (η) in lead-free systems remains challenging. Herein, a multi-scale high-entropy design strategy is proposed for (Bi0.5Na0.5)0.94Ba0.06TiO3-based relaxor ferroelectrics. The approach involves sequentially introducing (Sr0.7Bi0.2)TiO3 and (Bi0.5La0.5)(Nb1/3Mg2/3)O3 to construct a high-entropy system that simultaneously regulates material behavior across lattice, microstructural, and electronic structure scales. This coordinated approach induces strong lattice distortion and local random fields to disrupt ferroelectric order and stabilize polar nanoregions, while sluggish diffusion kinetics refine grain morphology and wide-bandgap ions enhance breakdown strength. Consequently, an ultrahigh energy storage performance with Wrec ∼10.72 J cm−3 and η ∼86.9% is achieved at 698 kV cm−1, accompanied by excellent energy storage stability and high hardness (∼8.58 GPa). This work demonstrates that multi-scale high-entropy design is an effective paradigm for developing advanced lead-free energy storage ceramics.

Electrocatalytic alcohol oxidation is pivotal for renewable energy conversion, yet its widespread application is hindered by generally low efficiency, necessitating the development of advanced catalytic systems with boosted electro-oxidation kinetics. In an alkaline electrolyte, the effect of alkali metal cations has been identified as a key impacting factor on the alcohol oxidation activity, but the underlying mechanistic interactions remains insufficiently explored. Here we elucidate the fundamental cation effects on hydroxyl (OH ads ) adsorption and subsequent surface bi-molecular kinetics in Pt (and alloys)-catalyzed alcohol electro-oxidations through combined electrochemical voltammetry, in situ surface enhanced infrared absorption spectroscopy (SEIRAS) and in situ electrical transport spectroscopy (ETS). Systematic evaluations reveal that alkali metal cations regulate the micro-electro-kinetics by modulating the surface coverage of OH ads , which acts bi-functionally as both reactant species and spectator in alcohol oxidations. A matching adsorption kinetics of OH ads and alcohol is key towards the optimal alcohol oxidation activity, providing valuable insights into the cation-mediated alloy catalyst systems and high-concentration conditions in alcohol fuel cells.

A Bi₄Ti₃O₁₂/BiOCl heterojunction with a coherent interface was constructed via a room-temperature ion-exchange process. • A Bi₄Ti₃O₁₂/BiOCl heterojunction with a coherent interface was constructed via a room-temperature ion-exchange process. • The photocatalyst exhibits excellent performance for the degradation of high-concentration, recalcitrant antibiotics. A strategy is reported for the in-situ fabrication of a Bi₄Ti₃O₁₂/BiOCl heterojunction with shared atomic layer through simple room-temperature ion-exchange on pure Bi₄Ti₃O₁₂. This strategic interfacial engineering, combined with a Type-II band alignment, the Aurivillius-type Bi₄Ti₃O₁₂ and BiOCl share the Bi₂O₂ 2+ layers at the interface, thereby dramatically accelerating the separation and migration of photo-generated carriers and ultimately significantly increasing the yield of photocatalytic reactive species. Consequently, the optimized composite photocatalyst exhibits exceptional performance in the degradation of high-concentration antibiotics. It achieves remarkable degradation efficiencies of 90.8% for sulfamethoxazole (20 ppm) within 120 min, 92% for tetracycline hydrochloride (40 ppm) and 78.6% ciprofloxacin (15 ppm) within just 30 min. Demonstrating superior photocatalytic performance compared to the previously reported analogous photocatalysts in recent years with respect to antibiotic degradation. Furthermore, the degradation efficiency of the as-prepared photocatalyst also demonstrates outstanding cycling stability, with a reduction of only 3.4% after 4 cycles. Therefore, this coherent Bi₄Ti₃O₁₂/BiOCl heterojunction photocatalyst exhibits immense potential for practical applications in environmental remediation.

Ceramic capacitors with stable dielectric responses at elevated temperatures are of great importance for advanced electronic applications. In this study, high-entropy-engineered (Ba 0.85 Sr 0.15 )TiO 3 –Bi(Mg 2/3 Ta 1/3 )O 3 solid solutions were developed to achieve broad-temperature dielectric stability. Among them, the composition with 25% and 30% Bi(Mg 2/3 Ta 1/3 )O 3 exhibit excellent dielectric properties, exhibiting room-temperature relative dielectric constants of 663 and 680, and dielectric losses of 0.6% and 1.1%, respectively. Particularly, they meet the X9R and X10R specification and dielectric loss of ∼0.6%, with capacitance variation less than ±15% from −74 °C to 265 °C, satisfying the X9R. The composition with 30% Bi(Mg 2/3 Ta 1/3 )O 3 shows the room-temperature dielectric constant of ∼680 and the dielectric loss of ∼1.1%, and showing TCC values within ±15% from −60 °C to 300 °C, which meets the X10R requirement. The improved dielectric temperature stability is associated with high-entropy-induced relaxor behavior together with enhanced high-temperature insulation characteristics, which jointly suppress dielectric loss and leakage current over a broad temperature range. These results demonstrate that high-entropy design is an effective route for developing high-performance temperature-stable dielectric materials for high-temperature capacitor applications.

To cater for the concept of global green development, it is of importance, in the bituminous road domain, to achieve the objective of the high-quality rejuvenation of waste bitumen. This paper investigates physical properties, rheological properties, morphology and molecular structure of rejuvenated SBS modified bitumen (SMB) with 1, 4-butanediol diglycidyl ether (BUDGE) or trimethylolpropane triglycidyl ether (TMPGE). The results of physical properties indicate that BUDGE and TMPGE can both improve the low-temperature ductility and penetration of aged SMB, and by contrast, BUDGE can make the aged SMB more flexible at low temperature. From the rheological properties, BUDGE or TMPGE can help restore the crack resistance at low temperature and somewhat decrease the rutting resistance at high temperature, which relies on the reduction of fatigue factor and rutting factor of aged SMB. FTIR spectra and fluorescence images show that the original structure of SBS can be partly rebuilt through the chemical reaction between the terminal groups on BUDGE or TMPGE and the oxygen-containing reactive groups on degraded SBS.

This study addresses antibiotic water pollution by synthesizing Zr-doped Bi₂₄O₃₁Cl₁₀ (Bi₂₄(₁₋ₓ)Zr₁₈ₓO₃₁Cl₁₀) photocatalysts via hydrothermal method for tetracycline hydrochloride (TC-HCl) removal. Zr doping ratios (6–14%) were systematically investigated, with the optimal BZOC4 (12% Zr) degrading 91.24% of 20 mg/L TC-HCl within 120 min under 500 W xenon lamp irradiation (pH = 9). Its reaction rate constant (0.0239 min −1 ) is triple that of pristine Bi₂₄O₃₁Cl₁₀. Zr doping reduces the band gap from 3.12 eV to 2.8 eV, improves visible light utilization (absorption edge red-shifted to 525 nm), accelerates electron transfer, and reduces e − /h + recombination—supported by UV –Vis DRS, PL, and electrochemical tests. Superoxide radicals (O₂ − ·) and holes (h + ) are primary active species, confirmed by radical trapping and ESR. TOC analysis confirms 32.4% mineralization of TC-HCl to CO₂ and H₂O.This work offers new design strategies for bismuth halide-based photocatalysts in antibiotic remediation by integrating structural regulation and electronic modulation via Zr doping.

Thermoelectric Mg 3 (Sb, Bi) 2 has emerged as a rising star in virtue of its promising thermoelectric performance and abundant constituent elements. However, its practical application is hindered by challenges in synthesis and the strong coupling between electrical and thermal transport properties. Herein, we propose a dual-pronged strategy that combines grain boundary engineering and phonon engineering to decouple electron and phonon transport in Mg 3 (Sb, Bi) 2 . By employing a tantalum-tube encapsulated melting technique together with Cu doping, the grain size is markedly increased to ∼25 µm, effectively suppressing carrier grain boundary scattering and enabling single-crystal-like electrical transport with a high carrier mobility exceeding 200 cm 2 V −1 s −1 . Meanwhile, atomic-scale alloy disorder and nanoscale Mg 2 Cu precipitates introduce strong phonon scattering, leading to an ultralow lattice thermal conductivity of 0.36 W m −1 K −1 . Eventually, a peak zT of 1.9 at 750 K and a high conversion efficiency of 10.6% at ΔT = 488 K are achieved, demonstrating the competitive performance of these materials and devices. This study not only provides new insights into the manipulation of grain boundary scattering, but also demonstrates the great promise of Mg 3 (Sb, Bi) 2 for waste-heat harvesting.

The bacterial resistance due to the abuse of conventional antibiotics is regarded as a major problem for bacterial-induced infections and chronic wound healing. There is an urgent need to explore alternative antimicrobial strategies and functional materials with excellent antibacterial efficacy. Herein, guanosine monophosphate (GMP) and glucose oxidase (GOD) were coordinated with copper ions to obtain a bi-functional hybrid nanoflower (Cu-GMP/GODNF) as a cascade catalyst for promoting antibacterial efficacy. Besides the efficient conversion of glucose to hydrogen peroxide, the produced gluconic acid by loading GOD can supply a compatible catalytic environment to substantially improve the peroxidase activity for generating more toxic reactive oxygen species (ROS). So, the glucose-powered cascade catalytic reaction effectively killed bacteria. Moreover, H2O2 self-supplied by glucose can reduce harmful side effects of exogenous H2O2. Meanwhile, the adhesion between the Cu-GMP/GODNF and the bacterial membrane can enhance the antibacterial efficacy. Therefore, the achieved bi-functional hybrid nanoflower exhibited high efficiency and biocompatibility for killing bacteria in diabetes-related infections.

High capacity, long cycle life, and fast kinetics are highly desired for alloying anodes in sodium ion capacitors (SICs). However, the huge repeatedly volume changes during the alloying/dealloying process cause electrode pulverization , seriously degrading the capacity and cycling stability. To address this issue, we developed a microwave irradiation technology for the in-situ growth of nano-sized Bi uniformly anchored on the surface of carbon nanotubes (CNTs). The as-synthesized freestanding electrode film effectively retards the pulverization of Bi nanoparticles , enabling fast sodium storage kinetics for high-power performance (278.1 mAh g −1 @ 30 A g −1 ), as well as high-capacity retention of 94% for over 3,500 cycles. The coin-cell type SICs of a Bi/CNTs anode paired with an activated carbon (AC)/CNTs cathode can deliver a maximum energy density of 128.5 Wh kg −1 and a high power density of 12.3 kW kg −1 with a remaining energy density of 85 Wh kg −1 . Additionally, the flexible quasi-solid SICs using a gel electrolyte demonstrated a high volumetric energy density of 21 mWh cm −3 with good cycling stability (90%) for over 1500 cycles. These results show great promise for our developed SICs as the next-generation energy storage to bridge the performance gap between batteries and supercapacitors , as well as for flexible energy storage applications.
