In this study, the magnetic modification of rectorite was conducted to enhance its regenerability and surface electronegativity. When using the raw rectorite, the removal rate of ciprofloxacin was 78 % and the recovery rate was only 26 % after six regeneration cycles. However, with magnetized modified rectorite (M-REC), the removal rate of ciprofloxacin was 97 % and the recovery rate exceeded 75 %. The magnetic properties, easy magnetic separation and enhanced surface electronegativity of M-REC were confirmed through SEM, TEM, VSM, XRD, BET and XPS characterization. After six regeneration recycles, the basic skeleton structure of M-REC remained largely unchanged, indicating that has excellent stability. Additionally, the adsorption kinetics and thermodynamics of M-REC were investigated, and the Langmuir model accurately described the adsorption isotherm. The adsorption kinetics data fit the pseudo-second order models. The adsorption rate was determined by the number of available adsorption sites on the M-REC surface, and the removal process was primarily driven by chemisorption. Therefore, M-REC is an environmentally friendly adsorption material with potential applications in environmental remediation. © 2025

The photocatalytic N2 reduction under ambient conditions offers a promising alternative to the energy-intensive and carbon-emitting Haber-Bosch process. However, unidirectional or symmetric adsorption between the active sites of a single metal and nitrogen molecules is not sufficient to activate the inert N2, thus limiting the further improvement of the nitrogen fixation performance. Here, Fe dopant has been introduced into MoO3-x nanowires by replacing Mo atoms to form Fe-Mo bimetallic active sites for nitrogen fixation under natural conditions. Experimental and theoretical findings demonstrate that the introduction of Fe induces a significant polarization in the charge structure of active site. In contrast to the conventional nitrogen fixation step, the Fe-Mo active sites shifted the N2 hydrogenation from the associative alternating pathway to the more advantageous associative distal pathway by promoting N2 adsorption/activation and lowering the energetic barriers of the rate-limiting step during nitrogen reduction. Moreover, the improved stability suggests that the doped Fe can act as a charge-compensating species, accepting electrons and therefore effectively improving the stability of oxygen-containing vacancy catalysts. Thus Fe-doped MoO3-x exhibits a nitrogen fixation performance of 742.92 μmol g-1 h-1. This study provides valuable insights into the design of catalysts based on their electronic structure and optimizing photocatalytic nitrogen fixation. © 2024, The Authors. All rights reserved.

Polycaprolactone (PCL) is biocompatible aliphatic polyester with many possible applications in the medical field. Porous electrospun Polycaprolactone (PCL) fibers were produced through a non-solvent induced phase separation mechanism, using binary solvent systems with different properties. The effect of single and binary solvent systems on the fiber size and surface morphology were investigated. Dichloromethane (DCM) was used as a good solvent in mixtures with a poor solvent, dimethyl sulfoxide (DMSO), in order generate to pores on the fiber surface. The effect of polymer concentrations (12%, 14% and 16%) w/v and solvents ratios (9:1, 7:3 and 5:5) v/v were investigated on nanofiber formation. During electrospun fiber production, the flow rate was 0.12mL/h, the distance between needle and collector was 15cm and the applied voltage was 12kV. SEM micrographs showed successfull production of PCL nanofibers with different solvents. With increasing the polymer concentration and changing the ratio of the solvents porous PCL electrospun nanofiber was produced. In binary solvent systems 16% PCL polymers and (7:3) % solvents ratio solution make even, beads free, smooth and porous PCL electrospun fiber. Combining the inherent properties of the PCL matrix with the characteristic of nanofibrous mats, result in promising materials that can be suitable for different applications, including biomedical applications. The advantages of nanofibrous structures include large surface area, small diameter of pores and high porosity, which make them of great interest in different applications. Porous electrospun fiber is better for cell development. © 2021. All rights reserved.

Steel ring reinforcement technology is an effective method to eliminate the damage of tunnel structure caused by ground load, surrounding foundation pit and underground water source. The grouting material used to fill the gap between the tunnel segment and the steel ring should have the characteristics of low viscosity, high strength, rapid curing at room temperature and anti-subway vibration. In this work, a special polyurethane modified epoxy resin grouting was fabricated to overcome the inherent brittleness of epoxy resin, and was combined with the reactive diluent and the amine curing agent to suit the above applications. The results showed that both tensile and impact strength of epoxy resin grouting modified by polyurethane were improved obviously compared with those without modification, presenting an obvious toughening effect. Although the viscosity increased slightly, it can still meet the perfusion requirements of steel ring reinforcement of subway tunnels. © Published under licence by IOP Publishing Ltd.

Magnolol a Chinese medicinal herb that has been used for treating cough, phlegm and inflammation for a thousand years. Appreciating its low absorption rate that limits its use, there is need to develop porous magnolol foams that are light weight, low density, portable while maintaining tissue integrity to expand its application. This study proposes an innovative method for creating a biocompatible foam through a one-pot process involving reacting magnolol with sulfhydryl compounds, utilizing a thiol-ene click reaction to create a foam. Various foams were systematically formulated by adjusting the degrees of cross-linking, concentrations of the foaming agent 2,2'-azobis(2-methylpropionitrile) (AIBN), and the temperature and pressure conditions during the foaming. AIBN acted both as a blowing agent and initiator, triggering cross-linking in the polymer solution by releasing free radicals and nitrogen gas. This initiated rapid expansion when a critical viscosity threshold was reached, ultimately curing the foam. The optimal foaming efficiency was achieved when the molar ratio of allyl to mercapto groups was maintained at 1:1, pentaerythritol tetrakis(3-mercapto-propionate) (PETMP) identified as the optimal sulfhydryl compound. Increasing the dosage of AIBN enhanced gas generation, further expanding foam volume, pore size and porosity, the foam is lightest when the amount of AIBN is 7.5%. When magnolol-based foams were prepared under sealed conditions at 100°C, without external pressure, they exhibited large, uniformly distributed pores and excellent water-absorbing properties. Moreover, the resulting foams demonstrated remarkable thermal stability and resilience. These findings offer a new design strategy for engineering high-performance functional magnolol foams with high biomass content. © 2025, The Authors. All rights reserved.

Aiming at the limitation of fabric color characterization with a single data source, multi-source data feature fusion method was used to characterize fabric color information. The correlation coefficient and the error of BP neural network color matching model are used for quantitative analysis. The results show that for cotton and polyester fabrics, the correlation coefficients of multi-data source fusion features are greater than 0.9, which is higher than that of single data source, and the characterization ability is stronger. At the same time, this method can significantly reduce the model error and improve the precision. The average error is less than 0.03, and the accuracy of the model is improved by more than 9% compared with the input of a single data source, which proves the effectiveness and universality of the proposed method.

Aqueous zinc batteries offer significant potential for large-scale energy storage, wearable devices, and medium-to low-speed transportation due to their safety, affordability, and environmental friendliness. However, the uneven zinc deposition at the anode side caused by localized reaction activity from the passivation layer presents challenges that significantly impact the battery's stability and lifespan. In this study, we have proposed an expandable and maneuverable gel sustained-release (GSR) treatment to polish the Zn metal, which in situ converts its native passivation layer into a composite interphase layer with nanocrystal zinc phosphate and flexible polyvinyl alcohol. Such a thin and uniform interface contributes to fast and homogeneous Zn ion transport and improved anti-corrosion ability, enabling uniform zinc deposition without dendrite growth and thereby improving the battery performance with high-rate ability and long cycle life. This GSR treatment method, characterized by its simplicity, low cost, and universality, facilitates the widespread application of aqueous zinc batteries. © 2025 Institute of Process Engineering, Chinese Academy of Sciences

In recent years, aluminum nitride (AlN) has attracted considerable attention for its high acoustic velocity and stable piezoelectric properties at high temperatures, making it a promising material for high-performance SAW sensors. However, simulation studies have identified higher-order transverse Lamb wave modes in AlN-based SAW resonators. These spurious modes reduce the sensor’s quality (Q) factor and cause frequency interference, affecting the signal-to-noise ratio and transmission range. This study effectively excites the piston mode by etching part of the piezoelectric material in the gap region to form a trench structure. Simulation results show that the trench design effectively creates a waveguide structure, suppressing transverse spurious modes and improving the overall device performance. The proposed trench structure presents a viable approach for advancing AlN-based SAW wireless sensor technology.

Aramid cord fabric is a novel polymer material with high strength, modulus, low thermal shrinkage, and good dimensional stability. It finds wide applications in marine development, oil exploration, transportation, special tires, and other fields. However, limited research has examined aramid cord fabrics' super-hydrophobic applications. Therefore, constructing a super-hydrophobic aramid cord fabric polymer material is necessary. This study utilized a simple surface sprinkling powder method to scatter titanium dioxide (TiO2) particles onto the rubber surface of aramid cord fabric. Through high-temperature and high-pressure processes, a TiO2/natural rubber (NR) polymer material with a superhydrophobic surface was created. The microstructure of the superhydrophobic surface was examined using scanning electron microscopy (SEM). Energy-dispersive X-ray spectroscopy (EDS) was employed for qualitative analysis of substances on the superhydrophobic surface. Fourier transform infrared spectroscopy was used to understand the nature of surface functional *** hydrophobicity and self-cleaning properties of the surface were evaluated using a contact angle meter and self-cleaning tests, respectively. Additionally, the mechanical durability of the superhydrophobic surface was tested through linear abrasion on sandpaper. The results indicated that increasing the TiO2 particle content enhanced both the hydrophobicity and mechanical durability of the TiO2/NR surface. When the TiO2 mass fraction reached 3%, the static contact angle (CA) of the TiO2/NR surface reached 160.1±3°, and the surface maintained its superhydrophobicity even after 150 abrasion cycles under a pressure of 2 kPa. Furthermore, the TiO2/NR superhydrophobic surface exhibited excellent self-cleaning properties. © 2024, The Authors. All rights reserved.
