Thermochromic phase change material (TC) is a temperature-responsive heat storage material. However, few TCs are renewable. In the present study, a renewable TC (RTC) composed of alizarin , myristyl myristate , and 1-hexadecanol was synthesized, demonstrating a color shift between orange and orange-red during phase transitions. To maintain the shape stability, the RTC was encapsulated within a wood-based cellulose/sodium methylsilicate framework, termed thermochromic wood composite-smart material (TWC-SM). This framework altered the chemical structure of alizarin , resulting in a color shift between greyish-purple ( L : 26 ± 1, a : 4 ± 1, b : −6 ± 1) and deep-purple ( L : 14 ± 2, a : 1 ± 1, b : −3 ± 1) for TWC-SM during phase changes, indicating a distinct thermochromic mechanism compared to RTC. Specifically, TWC-SM appears greyish-purple below 52 °C, where the benzene ring of alizarin features two fixed O groups and an additional -OH group. At temperatures above 70 °C, it turns deep-purple as the -OH group loses a hydrogen ion. TWC-SM exerts a pronounced thermochromic effect, conferring temperature-responsive functionality. Moreover, the solid-liquid phase-changing enthalpy of RTC is 186.78 J/g, and the wood-based cellulose/sodium methylsilicate framework ensures the shape stability of RTC within TWC-SM. Consequently, the average temperature of TWC-SM is at least 5.56 °C higher than that of untreated wood over 60 min following identical thermal treatment. This finding shows the potential of the framework for practical applications in temperature-responsive heat storage materials. This study reveals the structure-activity relationship between RTC and the framework within TWC-SM, which is key to the development of practical applications of RTCs.

Real-time and accurate detection of moisture content in insulating oil is crucial for the safe operation of oil-filled electrical equipment. This study presents a method for preparing hydrophobic porous PI films for moisture sensing using supercritical CO 2 foaming (SCF) technology. The resulting porous PI films have a uniform and dense nanometer-scale microporous structure, with a water contact angle of 111.7°, indicating strong hydrophobicity and enabling the mitigation of hysteresis-induced measurement inaccuracies. Compared to sensors made using traditional methods such as non-solvent induced phase separation (NIPS), the moisture sensors fabricated using this method exhibit a response time of 10 s, with humidity hysteresis reduced from 9.1 %RH to 2.3 %RH, achieving both fast response and low humidity hysteresis. This method also holds broad application prospects in areas such as permeation membranes and energy.

Metal–Organic-Frameworks (MOFs) are commonly used as microwave-absorbing materials after pyrolysis treatment. Rare researchers treat MOFs as non-conductive materials and use them as absorbing materials directly. In this paper, MOFs@P-C-800 composite materials are prepared adopt to hydrothermal and ultrasonic dispersion methods by regulating the morphological characteristics of MOFs and the content of P-C-800. As for the Co-BDC-P-C-800, the maximum reflection loss reaches −18.4 dB at 14.29 GHz and the effective absorption bandwidth (EAB) achieves 3.87 GHz from 13.5 to 17.37 GHz. After the contents of P-C-800 is adjusted, the Co-BDC-P-C-800 (0.05 g) exhibited excellent microwave absorption performance, the maximum RL value of −60 dB at 13 GHz with a thickness of 2.0 mm, and the EAB achieves 5.91 GHz from 12.02 to 17.93 GHz. This paper not only provides new application direction for MOFs, but also offers a promising direction for the research and development of absorbing materials.

Flexographic printing plates, which are typically composed of a metal substrate, an adhesive layer, and a poly(vinyl alcohol) (PVA) photosensitive layer, are essential for achieving high-resolution patterns in flexographic printing technology. The adhesive layer, serving as the bonding interface between the metal and PVA layers, must exhibit strong adhesion to both metal and polymer surfaces, along with high toughness, mechanical strength, solvent resistance, and durable adhesion to meet the mechanical and chemical requirements of flexographic printing technology. Herein, inspired by the structure of mussel foot silk protein, this study integrates carbon–carbon double bonds, catechol, alcohol hydroxyl, and amino ester groups into a single polymer chain via a two-step reaction. Benefits to its rigid-flexible cross-linked network, the obtained adhesive exhibits good strength, modulus, and toughness. Specifically, its tensile strength, tensile modulus, elongation at break, and impact strength are 1.70 MPa, 0.85 GPa, 19.3 %, and 2.97 kJ/m 2 , respectively. Furthermore, the adhesive achieves a 180° peel strength of 2.26 N/mm with tinplate and 3.89 N/mm with flexographic printing plates. Notably, after 7 days of immersion in water, ethanol, and dimethylformamide, the 180° peel strength retention rate was as high as 96.9 %, 96.2 %, and 93.9 %, respectively. After being stored at room temperature for 28 days, the 180° peel strength retention rate reaches up to 98.3 %, highlighting its long-lasting durability. This mussel-inspired group integration strategy provides a straightforward and efficient approach for developing high-performance multi-functional adhesives, with significant potential for advancing flexographic printing.

Fabricating inorganic ceramics with stable high-temperature electromagnetic (EM) attenuation properties via the construction of three-dimensional (3D) nanofiber networks continues to pose significant challenges. In this work, the dielectric properties and microwave attenuation performance were significantly enhanced through the precise morphological and architectural control of a 3D TiO₂ nanowire (TiO₂ nws) network within Sc₂Si₂O₇, which was achieved by modulating the sintering temperature during coprecipitation and sintering. The TiO 2 nws/Sc₂Si₂O₇ (ST-800, sintered at 800 ℃) exhibited excellent microwave absorption properties, with a minimum reflection loss (RL min ) of –21.45 dB at 2.25 mm and an effective absorption bandwidth (EAB) reaching 3.7 GHz at a matching thickness of 2.55 mm. The radar cross-section significantly decreased by 17.28 dB·m² at 0°. Moreover, ST-800 has a broad temperature range from 100 600 °C, with an RL below –20 dB, an EAB exceeding 3.8 GHz, and a matching thickness of less than 2.75 mm. This stable and excellent microwave absorption performance at elevated temperatures can be attributed to the well-maintained impedance matching behavior, along with the synergistic compensation between the polarization loss and conduction loss across a broad temperature range. These findings provide valuable guidance for the development of high-temperature stable EM wave absorbing materials.

Non steroidal anti-inflammatory drugs (NSAIDs) are widely used for analgesic and anti-inflammatory purposes but are often hampered by side effects such as gastrointestinal issues. Flurbiprofen, a potent NSAID, has significant therapeutic potential but may cause adverse effects due to its non-selective cyclooxygenase (COX) inhibition. This study aimed to enhance its efficacy and reduce side effects by developing flurbiprofen-loaded ZIF-8 nanoparticles (FP@ZIF-8). ZIF-8, with its high porosity, pH sensitivity, and biocompatibility, serves as an excellent carrier for targeted drug delivery. FP@ZIF-8 nanoparticles demonstrated successful flurbiprofen encapsulation with a drug loading rate of up to 53% and showed pH-responsive drug release. In vitro studies revealed that FP@ZIF-8 nanoparticles not only promoted the proliferation of human umbilical vein endothelial cells (HUVECs) but also significantly reduced lipopolysaccharide (LPS) -induced reactive oxygen species (ROS) production in RAW264.7 macrophages. In vivo experiments further indicated that FP@ZIF-8 effectively alleviated inflammation-induced pain in mouse models and downregulated key inflammatory cytokines. The biosafety assessment confirmed the excellent biocompatibility and safety of FP@ZIF-8 nanoparticles. These findings suggest that FP@ZIF-8 is a promising drug delivery system for treating inflammatory pain conditions.

Developing cost-effective oxygen evolution reaction (OER) catalysts for industrial current densities remains challenging, hindered by adsorbate evolution mechanism (AEM) scaling limitations and reconstruction instability. Here, we report a heterointerface-engineered Ni 3 S 2 /NiFeOOH catalyst formed via in-situ electrochemical reconstruction of Ni 3 S 2 /NiFe-LDH. Interfacial charge redistribution stabilizes high-valent Ni 3+ /Fe 3+ species and generates coordinatively unsaturated lattice oxygen sites, thereby activating the lattice oxygen mechanism (LOM). Combined operando spectroscopy, pH-dependent kinetics, and isotope labeling confirm LOM dominance. Further theoretical analyses reveal that the heterointerface downshifts the metal d -band center and upshifts the O 2p -band center, optimized intermediate adsorption free energy. Benefiting from the compatible multi-mechanism, the reconstructed catalyst demonstrates outstanding OER performance, only requires overpotentials of 196/305 mV to drive current densities of 10/1000 mA cm −2 in alkaline media, with robust stability for over 500 h. This work clarifies how interfacial electronic modulation connects pre-catalyst reconstruction to LOM activation, providing a scalable design strategy for high-current-density OER electrocatalysts. Graphical Upon electrochemical activation, Ni 3 S 2 /NiFe-LDH catalysts undergo transformation to Ni 3 S 2 /NiFeOOH. This structural reconstruction not only exposes additional catalytic active sites but also activates lattice oxygen species, thereby triggering the lattice oxygen reaction pathway. By circumventing the thermodynamic constraints inherent to the adsorbate mechanism, the reconstructed catalyst achieves a reduced overpotential, ultimately enhancing its oxygen evolution reaction (OER) catalytic performance.

Purpose Colorectal cancer (CRC) is a prevalent cancer worldwide, with metastasis significantly contributing to its high mortality and poor prognosis. This study focuses on the impact of Alkaline Phosphatase, Placental (ALPP) on epithelial-mesenchymal transition (EMT) in colorectal cancer cells and its role in the Wnt/β-catenin signaling pathway.Patients and Methods Differential ALPP expression was first interrogated in metastatic versus non-metastatic CRC samples from The Cancer Genome Atlas (TCGA-CRC) cohort. Functional validation was subsequently performed in vitro with HT29 and HCT116 cell lines engineered for ALPP overexpression or CRISPR/Cas9-mediated knockdown. Proliferation, migration and invasion were quantified by CCK-8, wound-healing and Transwell assays; EMT and Wnt/β-catenin signaling were assessed by Western blot.Results Bioinformatics analysis revealed significantly different ALPP expression between metastatic and non-metastatic patients. In vitro experiments further revealed that ALPP overexpression drives proliferation, invasion, migration and, consequently, metastasis of HT29 and HCT116 colorectal cancer cells, whereas ALPP knockdown abolishes these EMT-dependent effects. Increased ALPP expression resulted in increased levels of N-Cadherin, Vimentin, and Snail proteins, along with a decrease in E-cadherin protein expression, in contrast to findings following ALPP knockdown. Furthermore, ALPP overexpression was also associated with Wnt/β-catenin signaling pathway activation.Conclusion ALPP was found to act as an oncogenic factor in colorectal cancer cell lines HT29 and HCT116, stimulating cell proliferation and facilitating EMT. Abnormal activation of the Wnt/β-catenin signaling pathway was also found to be linked to increased ALPP expression.

Mining chains operating in adverse underground environments and experiencing elevated coal transportation volumes are susceptible to critical failures including overloading, chain jamming, and fracture due to their role as essential transmission components. Realtime chain strain monitoring systems provide continuous assessment capabilities and early warning of potential failure events. Conventional strain sensors employed for tension monitoring exhibit significant limitations including insufficient sensitivity, excessive power requirements, and substantial dimensional constraints. In this investigation, we have synthesized strain sensors specifically engineered for downhole applications by leveraging the exceptional properties of graphene and HfSe2. The integration of HfSe2 into graphene-based composites resulted in the formation of heterointerfaces, which enhanced the sensors’ sensitivity and linearity. These sensors demonstrate superior performance characteristics, including enhanced gauge factor (GF = 22.8) within the linear strain range of 0–2000 με, exceptional linearity ( $R^{2}_{L} = 0.98$ ), ultralow detection threshold (100 με), and minimal power consumption (2.05 mW), while maintaining measurement accuracy across extreme thermal conditions (0 °C–60 °C). The acquired strain signals underwent fast Fourier transform (FFT) analysis, with subsequent application of a Butterworth filter to attenuate high-frequency components and mitigate environmental noise interference. The developed graphene-/HfSe2-based strain sensor substantially enhances monitoring precision and operational safety, presenting significant implementation potential for advanced mine intelligence systems.

Gas-assisted coaxial electrospinning (GACES), a simple and versatile technique for the large-scale fabrication of coaxial nanofiber membranes, possesses significant industrial potential across advanced manufacturing sectors including semiconductors—particularly for fabricating high-precision dielectric layers, high-uniformity encapsulation materials, and flexible semiconductor substrates requiring tailored core-shell architectures. However, there is still a lack of relevant studies on the effective regulation of the core-shell structures of coaxial fibers based on GACES, which greatly limits the batch preparation and wide application of coaxial fibers. Finite element simulation analysis of the flow field and development of the coaxial jet mechanics model with a gas-driven flow field—two key methodologies in this study—successfully uncovered the influence mechanism of gas-assisted flow fields on the core-shell structures of coaxial nanofibers. By adjusting the gas-assisted flow fields parameters, we reduced the total diameter of coaxial fibers by 47.33% (average fiber diameter: 334.12 ± 16.29 nm → 175.98 ± 1.18 nm), decreased the shell thickness by 72.98%, increased the core-shell ratio by 289% (core-shell ratio: 0.49 → 1.91), and improved the uniformity of the total diameter distribution of coaxial fibers by 30.64%. This study delivers a practical conceptual framework and robust experimental underpinnings for the scalable fabrication of coaxial nanofiber membranes with controllable core-shell structures, thereby promoting their practical application in semiconductor devices such as ultra-thin dielectric layers, precisely structured encapsulation materials, and high-uniformity templates for nanoscale circuit patterning.

Aqueous zinc-ion batteries (AZIBs) offer high safety, low cost, and environmental compatibility, yet their large-scale deployment is hindered by dendrite growth and severe side reactions arising from non-uniform Zn 2+ deposition. Constructing artificial interphase layers (AILs) to regulate Zn 2+ nucleation and growth has emerged as an effective strategy to mitigate these issues. One-dimensional (1D) Sn metal, featuring a high specific surface area, tunable structure, strong zinc affinity, and high hydrogen evolution overpotential, is an ideal candidate for interphase engineering. However, existing synthesis methods for 1D Sn, which rely on template-assisted electrodeposition, face challenges in scalability. In this work, Sn whiskers are synthesized via the mechanochemical decomposition of the Ti 2 SnC MAX phase and employed to construct a three-dimensional (3D) Sn whisker network as an artificial interphase layer on zinc anodes (Sn whisker@Zn). This continuous network effectively guides Zn 2+ migration and deposition, promotes preferential growth along the (002) crystal plane, reduces local current density, and suppresses dendrite formation. Simultaneously, it retards corrosion and inhibits the formation of by-products. Symmetric cells based on Sn whisker@Zn anodes exhibit exceptional cycling stability, sustaining over 1600 h of stable operation at 1 mA cm −2 with a capacity of 0.5 mAh cm −2 , and exceeding 1000 h at a high current density of 10 mA cm −2 . Moreover, the Sn whisker@Zn||NH 4 V 4 O 10 full cell retains 89.94 % of its capacity after 1400 cycles at 5 A g −1 , demonstrating strong application potential. This approach provides a scalable and effective strategy for developing durable zinc anodes, advancing the prospects of AZIBs in energy storage systems.

Lightweight ablative thermal protection materials (TPMs) with excellent ablation, thermal insulation, and anti-oxidation are urgently needed for aerospace vehicles. Herein, a distinct strategy was proposed that uses aerogel-like polysiloxane (SiA) as a matrix, and carbon-bonded carbon fiber (C/C) composite as reinforcement to construct a lightweight SiA impregnated C/C (C/C-SiA) composite, through vacuum impregnation, sol–gel, and atmospheric pressure drying. The intriguing characteristics including high mechanical strength and stiffness, thermal stability and oxidation resistance, and a low thermal conductivity of 0.063 W/(mK) were integrated into the low-density (0.238–0.306 g/cm 3 ) C/C-SiA. The synergistic effect originated from pyrolysis products of SiA including silicon oxycarbide ceramic to inhibit oxygen diffusion and pyrolysis gas to retard convective heat transfer, the high emissivity surface re-radiation to dissipate heat and transverse thermal conductivity to regulate heat transfer by C/C, enables C/C-SiA to deliver remarkable thermal insulation performance (20 mm backside temperature below 40°C on a heating plate for 1800 sec) and ablation resistance (near-zero surface recession of 0.18 μm/s exposed to 1300°C flame for 1200 sec). The ceramifiable strategy can be extended to other preceramic polymers, such as polycarbosilane, polysilazane, and ZrO 2 precursor, which may open a new avenue for improving lightweight ablative TPMs. Highlights Aerogel-like polysiloxane lightweight ablative material was fabricated. The synergistic effect gives excellent mechanical and thermal properties. Surface re-radiation and heat blockage dissipate the main heat continuously. In-situ formed ceramic to inhibit diffusion enables long-term anti-oxidation.
