Gas foaming-assisted decellularization improves porosity and cell removal in fish skin. • The matrix shows a porous structure with preserved collagen integrity and content. • The scaffold exhibits wet-state adaptability, rapid wettability, and high swelling capacity. • The material shows electromechanical response, biocompatibility, and antibacterial activity without exogenous agents. • This strategy enables valorization of fish by-products into marine-derived biomaterials for soft tissue repair. Tilapia skin, a major by-product of aquaculture, represents an abundant and sustainable resource for the construction of biomedical scaffolds, but its dense structure with limited pores limits the efficiency of conventional decellularization methods. In this study, a novel gas foaming-assisted decellularization strategy using sodium borohydride (NaBH 4 ) as foaming agent was designed and developed to fabricate decellularized tilapia skin matrix (dTSM). Some key parameters like NaBH 4 concentration and foaming time were systematically investigated. It was found that, under optimized conditions (2 M NaBH 4 , 30 min), the dTSM exhibited significantly enhanced porosity (70.2 ± 1.8% vs. 17.1 ± 2.9% in native skin), reduced residual deoxyribonucleic acid (DNA, 18.9 ± 5.4 ng/mg), and well-preserved collagen content and structure. Moreover, the obtained dTSM showed excellent hydrophilicity with complete water absorption within 5 s, a high swelling ratio (~300%), and improved mechanical adaptability under wet conditions (ultimate stress: 35.0 ± 3.7 MPa, elongation: 127.5 ± 21.5%). Stable piezoelectric outputs of 2.5–4.0 V and ~6 nA were generated under cyclic compression. Biocompatibility tests confirmed that the dTSM obtained from under optimized conditions exhibited low hemolysis (1.1 ± 0.6%) and effective support for cell adhesion and proliferation, while antibacterial rates exceeded 99% against both Escherichia coli and Staphylococcus aureus . This foaming-assisted approach offers a promising strategy for valorizing fish by-products into functional biomaterials for soft tissue regeneration and marine-based biomedical applications.

Chronic diabetic wounds complicated by biofilm infections resist healing because persistent bacterial colonization coexists with microenvironmental imbalances, including oxidative stress and inflammation. Conventional pharmacotherapy and wound care are limited by impaired local perfusion, which hinders both effective biofilm eradication and reversal of the pathological wound microenvironment. We developed an ultrasound-activated core–shell microneedle platform (CCA&Lut@MN) that combines sonodynamic gas cascade antimicrobial therapy with a ROS-responsive microenvironment modulation strategy. Upon ultrasonic stimulation, L-arginine–modified copper–cysteine nanoparticles (CCA) in the microneedle shell generate reactive oxygen species (ROS) and catalyze NO release from L-Arg, producing synergistic oxidative and nitrative stress that yields rapid bactericidal activity and effective biofilm eradication. The microneedle core consists of an ROS-responsive PVA-HP-luteolin hydrogel that degrades in response to elevated ROS in the microenvironment, releasing luteolin. Luteolin scavenges excess ROS and promotes macrophage polarization to the M2 phenotype, thereby enhancing angiogenesis and cell migration. In a diabetic rat wound model infected with MRSA , CCA&Lut@MN markedly reduced wound bacterial load, alleviated local inflammation and improved blood supply, and thereby accelerated wound healing. This microneedle platform produces synergistic antibacterial effects via sonodynamic therapy (SDT)–gas cascade reactions, modulates the pathological microenvironment, and improves local blood supply, offering a promising strategy for treating complex and refractory wounds.

Polyimide (PI) membranes face a trade-off between permeability and selectivity, limiting their gas separation applications. To address this, we synthesized 6FDA-DAM/DABA(DAM:DABA = 3:2) PI and two-dimensional COF-1 nanofillers, fabricating hollow fiber mixed matrix membranes (MMMs) via dry-jet wet-spinning. Under optimized conditions (25 cm air gap, 50 °C spinneret temperature, 30 °C NMP coagulation bath), the 10 wt % COF-1 incorporated membranes achieved optimal performance: tensile strength of 15.34 MPa; H2 and CO2 permeances of 79.3 GPU and 54.3 GPU, and ideal selectivities of 187.9 for H2/CH4 and 128.7 for CO2/CH4, respectively. The results demonstrate that the incorporation of COF-1 modifies solvent exchange during spinning, necessitating targeted optimization of spinning parameters to coordinate membrane structure and performance.

Optimizing the tribological performance of moving components with lubricating materials is crucial for reducing energy consumption and carbon footprint. Spin-coating two-dimensional materials represents an effective approach to lowering the friction coefficient of typical lubricating materials such as diamond-like carbon (DLC). However, the influence of third-body introduction on lubricant–environment interfacial interactions remains unclear. Herein, h-BN, which catalyzes carbon graphitization, was selected to systematically investigate its regulatory effect on the tribological behavior of DLC under an energy-gas CH 4 atmosphere. The synergistic effect between the tribo-catalytic action of h-BN and the intrinsic structure of the films leads to significant differences in the degree of friction coefficient improvement for DLC with distinct bonding structures: the friction coefficient of low-sp 3 -content DLC is reduced by 45%, while that of high-sp 3 -content and high-sp 2 -content DLC is significantly enhanced with a reduction of no less than 20%. Structural characterization of the tribological interface reveals that h-BN catalyzes graphitization at the sliding interface, transforming the transfer film on the wear scar from a Gr/amorphous carbon superlattice structure into a coexisting structure of continuous graphene and amorphous carbon. The formation of continuous graphene suppresses interfacial dehydrogenation and strengthens surface passivation. This study reveals the competitive mechanism between third-body tribo-catalytic graphitization and shear-induced gas adsorption at the DLC sliding interface, providing a new strategy for the design of ultra-low-friction DLC films.

Silicon carbide (SiC) catalytic membranes are promising for the simultaneous removal of NO and particulate matter from industrial flue gas, but catalyst-induced pore narrowing creates a trade-off between gas permeance and catalytic activity. Herein, we focus on pore-structure predesign and propose a defect-complementary strategy integrating particle-penetration suppression with catalyst-induced pore regulation. Large SiC particles were used to fabricate an enlarged-pore membrane without an intermediate layer, preventing particle penetration into the support and simplifying preparation. Subsequent controlled loading of VCeTi catalyst narrowed the enlarged pores to the desired size while introducing NH 3 -SCR functionality. This complementary pore-design strategy achieved high gas permeance and high catalytic activity by offsetting the initially enlarged pores with the catalyst-induced pore-narrowing effect, thereby breaking the permeance–activity trade-off. The optimized V/SiC-N50 catalytic membrane exhibited an average pore size of 9.9 μm and achieved 26% higher gas permeance than the conventionally prepared V/SiC-W40 membrane, together with over 90% NO removal efficiency at 250–430 °C and 99.99% PM 2.5 filtration efficiency. Moreover, the strategy was successfully extended to tubular catalytic membranes, demonstrating its scale-up potential. In summary, this work provides a novel strategy for fabricating high-performance SiC catalytic membranes and establishes a design paradigm extendable to other fields.

Lithium carbon dioxide (Li-CO 2 ) batteries exhibit an ultrahigh theoretical energy density of 1876 Wh∙kg −1 and enable potential CO 2 capture for carbon neutrality. However, acidic CO 2 reacts with Li-metal anodes (CO 2 shuttle effect), causing pulverization and battery failure. Herein, we propose a separator gas barrier design strategy to address the critical issue of CO 2 shuttle-induced corrosion in Li- CO 2 batteries. The core of this strategy lies in a diamond-like carbon (DLC)-modified separator, which is engineered to possess exceptional gas barrier properties. Theoretical calculations and systematic experimental verifications collectively confirm that this separator efficiently suppresses the CO 2 shuttle effect, fundamentally mitigating Li-anode corrosion. Notably, the Li-CO 2 battery with this separator achieves a long cycle life over 1200 h (500 mAh∙g −1 , no extrinsic metal-based catalyst)—over 5 times longer than that with a pristine separator (240 h). This work provides a novel, universal design paradigm to enhance the cycling stability of metal-gas batteries (e.g., Li-O 2 , Na-CO 2 ), addressing a long-standing challenge in high-performance metal-gas energy storage systems by using separators as “gas barriers” to protect metal anodes.

In this research, Langmuir-Blodgett (LB) composite films were fabricated by integrating phthalocyanine (Pc) with derivatives of perylene diimide (PDI) and naphthalene diimide (NDI). The potential applications of these films in chemical gas sensing and surface-enhanced Raman spectroscopy (SERS) were investigated. The LB technique enables precise regulation of molecular arrangements within films, rendering them highly effective for applications as sensitive sensors. Upon exposure to NH₃ and HCl gases, the composite films exhibited good sensitivity, demonstrating their potential in chemical sensing applications. By employing R6G as a probe molecule, the films demonstrated remarkable SERS performance, distinguished by their uniformity, reproducibility, and amplified signal intensity, achieving an enhancement factor (EF) of 1.76 × 10⁵. This work demonstrates rapid colorimetric response to NH₃/HCl and achieves a high SERS enhancement factor of 1.76 × 10⁵, confirming the significant potential of these LB films for real-world sensing applications.

Hydrogen sulfide (H 2 S), emerges as a toxic gas that poses significant threats to human life and health, even at low concentrations (100 ppb). Therefore, the detection and monitoring of H 2 S are crucial for ensuring mining safety. Herein, zinc stannate (Zn 2 SnO 4 , ZTO) was synthesized using hydrothermal method, and copper-doped zinc stannate material (xCuZ) were synthesized by in-situ derivation of metal organic frameworks (MOFs). A ppb-level H 2 S gas sensor with rapid response and recovery was developed. The material with a Cu addition of 20 wt% (20CuZ) exhibited the optimal performance, with a sensitivity of 8 to 10 ppm H 2 S at 275 °C, which was approximately 8 times higher than that of pure ZTO, and surprisingly, exhibited high signal-to-noise ratio and rapid response and recovery characteristics (21 s/27 s) at ultra-low concentrations of 10 ppb. The improvement in gas sensing performance can be primarily attributed to the significant adsorption capability of Cu for H 2 S. Furthermore, the incorporation of Cu into the ZTO material induces lattice defects and increases the concentration of oxygen vacancies, thereby enhancing the gas sensing performance. The sensor produced in this study has the potential to mitigate the risks with mining operations while advancing the development of gas sensor technology.

Lead-free halide double perovskites have garnered extensive research attention due to their outstanding environmental protection performance, structural tunability, and excellent photoelectric properties. However, stable multimode luminescent perovskite materials and more extensive application research remain urgent problems to be solved. In this study, holmium-based lead-free double perovskite with good resistance to thermal quenching was successfully synthesized. The up-conversion luminescence (UCL) of perovskite can be regulated by doping Yb 3+ . Moreover, the emission wavelength can be effectively regulated by adjusting the doping concentration of Yb 3+ and the power of the excited laser. In addition, the aramid staple fiber (ACFs) and polyphenylene sulfide (PPS) composite fiber paper, after being modified with lead-free perovskite, exhibits luminescent properties under ultraviolet (UV) light and near-infrared (NIR) light. The modified luminescent fibers maintain their original flexibility and have good luminescent stability. After being stored in industrial acidic gases for 48 h, the luminescent fibers still maintained good luminescence performance, and no obvious luminescence quenching was observed. Surprisingly, the modified composite fibers also have good piezoelectric properties. The piezoelectric properties of perovskite piezoelectric fibers have been significantly improved through the doping of Yb 3+ . Its maximum output voltage is 17 V, and the response time is 9 ms. Perovskite-type piezoelectric fiber devices exhibit good output stability in humid environments. Multimode emission lead-free perovskite and its functional textiles will have strong competitiveness in the fields of flexible wearable fabrics and intelligent sensing and reality.

To enhance the integration of metal oxide semiconductor (MOS) gas sensor array in electronic nose, a sensor array structure based on multiplex sensing electrodes was proposed. Four multiplex sensing electrodes were designed and fabricated on silicon substrate. A heterogeneous sensing material, consisting of SnO 2 thin film and aligned Co 3 O 4 nanofibers, was subsequently prepared on the substrate by magnetron sputtering and electrospinning. By combining different sensing electrodes, the surface-modification-type sensors of SnO 2 @Co 3 O 4 and Co 3 O 4 @SnO 2 and the heterojunction-type sensors of SnO 2 -Co 3 O 4 and Co 3 O 4 -SnO 2 were constructed and formed the gas sensor array. At the operating temperature of 270 °C, the sensors on the array exhibited distinctive responses to ethanol. Co 3 O 4 @SnO 2 exhibited the highest response of 48 to 50 ppm ethanol among all the sensors. Toward the same concentration of ethanol, SnO 2 -Co 3 O 4 and Co 3 O 4 -SnO 2 showed the shortest response time of 1 s, while Co 3 O 4 -SnO 2 additionally presented the shortest recovery time of 34 s. the four sensors also showed different selectivity responses to the gases of ethyl acetate, benzene, methanol and isopropanol. Besides, a hybrid model of CNN-transformer was used to analyze the collected gas response signals of Chinese baijiu with varying concentrations of edible alcohol. With the dataset from the sensor array, the model converged rapidly and achieved a recognition accuracy of 98%. These results confirmed that the sensor array based on multiplex sensing electrodes was an effective design for the integrated gas sensor arrays of electronic noses

The reverse water-gas shift reaction (RWGSR) is essential for converting CO 2 into fuels using renewable hydrogen, but it remains challenged by the difficulty of simultaneously maximizing catalyst activity, selectivity, and stability. These limitations stem from thermodynamic constraints – specifically, the Gibbs-Curie-Wulff theorem - which restricts the synthetic accessibility of high-energy micro-faceted nanocrystals via conventional methods. To address this, we introduce a near-surface “quasi-hyperbaric” ammonia strategy that integrates atmospheric-pressure processing with in-situ ammonia decomposition. This approach enables the controlled synthesis of molybdenum nitride nanocrystals with preferentially exposed high-energy (112) microfacets. These facets promote CO 2 activation through a hydrogen-assisted redox mechanism, driven by geometrically confined and stabilized Mo-N/M-O hybrid active sites. The resulting catalyst outperforms the benchmark Pt/CeO₂, which typically suffers from CO selectivity below 92%. Our catalyst achieves near-equilibrium conversion (56%) at a space velocity (24000 ml/g cat /h), with 100% CO selectivity and outstanding stability (≤ 1% deactivation over 250 hours).

During the transportation of oil and gas, the coexistence of wax crystals and natural gas hydrates is becoming an increasingly prominent problem. The deposition of these solids is likely to result in the pipeline blockage, which adversely affects the flow efficiency and safety of oil and gas. To address this issue, researchers have proposed jointly adding wax inhibitors and hydrate inhibitors to improve flow assurance. However, due to the significant differences in the mechanisms of various inhibitors, the interaction effects among wax inhibitors, hydrate inhibitors, wax crystals, and hydrates may potentially undermine the inhibitory efficacy. To better clarify this issue, this paper first provides a detailed elaboration on the types, mechanisms, and interaction relationships of various inhibitors, including kinetic inhibitors of gas hydrates, thermodynamic inhibitors of gas hydrates, antiagglomerates, wax dispersants, and pour point depressants. Subsequently, based on previous studies, the interaction process of hydrate inhibitors, wax inhibitors, hydrates, and wax crystals in waxy oil–gas–water multiphase systems is reviewed. Finally, this paper puts forward possible interaction mechanisms between wax inhibitors and hydrate inhibitors, providing useful references for researchers in this field.
