The design and application of high‐tungsten (W) superalloys represent an effective strategy for enhancing the high‐temperature performance of superalloys. However, the associated deterioration of mechanical properties caused by high refractory element content remains an urgent issue to be resolved. A model high‐W superalloy with Al contents of 3, 4, 5, and 6 wt% was designed to study the optimization mechanism of Al content. The effects of Al content on the microstructure and stress rupture properties were investigated. The results of thermodynamic calculations and microstructural observation demonstrated that increasing the Al content promoted the precipitation of both the γ′ and α‐W phases. The peak stress rupture life was achieved at an Al content of approximately 5 wt%. This optimum is attributed to the competing strengthening mechanisms: increased Al content enhanced precipitation strengthening but concurrently reduced the solid solution strengthening of W as it partitioned into α‐W precipitates. Thus, the optimized performance at 5 wt% Al resulted from a balance between these mechanisms. The regulation of Al content enabled control over the microstructural morphology, which in turn enhanced the stress rupture life at elevated temperatures. This work provides novel insights and theoretical support for the development and application of high‐W superalloys.

Graphene aerogel (GA) as a revolutionary carbonaceous material is potentially applied in many fields due to its unique porous structure, low density, and excellent electronic conduction properties. More and more scientists pay their attention on GA research, especially in energy, environmental protection, and catalytic technology. The properties of GA can be enhanced or changed by modification in order to obtain GA with high‐performance or new functions. Liquid‐metal (LM)‐modified GA (GA/LM) were first synthesized using the bubble template method. Then, the resulting composite material with excellent thermal conductivity was successfully prepared by impregnating the preprepared GA/LM into polydimethylsiloxane (PDMS) solution. Comparison with that of GA/LM, the thermal conductivity of the GA/LM‐PDMS was increased by 14.77 times. Its glass transition temperature reached 66.79°C. Moreover, the composite exhibits pronounced anisotropic thermal management characteristics, demonstrating its direction dependent in heat transfer performance. This highly anisotropic structural design can effectively accelerate heat dissipation, which is beneficial for the operation efficiency and service life of electronic devices.

This review provides a comprehensive overview of recent advancements in dental bioinks and their applications in oral tissue engineering, particularly for dental restoration materials. It highlights the pivotal role of bioinks in cell patterning, biomaterial fabrication, and their impact on dental tissue regeneration. Over the past decade, significant progress has been made in the development of diverse bioink formulations, including single‐component, multicomponent, dynamic, and nanocomposite systems, each with unique properties tailored to dental tissue engineering. Drawing on a wide range of studies, this review discusses advances in printing techniques, bioink functionalization, in vivo evaluations, and applications in key oral tissues such as dental pulp, dentin, periodontium, alveolar bone, and gingiva. A major challenge is translating these bioinks into predictable clinical outcomes, as the oral cavity imposes strict requirements on in situ stability and functionality under a wet, mechanically active, and bacteria‐exposed environment. Critical challenges remain, including the need for efficient vascularization, overcoming mechanical heterogeneity, and sourcing appropriate cell types. Emerging strategies such as smart bioinks, intraoperative bioprinting, and artificial intelligence (AI)‐assisted design are highlighted as promising directions. In addition, the integration of nanomaterials, gene‐activated scaffolds, and immunomodulatory functions represents an important trend toward personalized and functional dental tissue restoration.

The conventional zinc coating can be transformed into a smart coating by incorporating pH‐responsive particles through the electro‐co‐deposition technique. Two different containers were considered: SBA‐15 and ZnO, for loading the inhibitor 2‐benzothiazolylthio‐succinic acid (BTSA). A sustained release was achieved by encapsulating it with a polymer, poly(diallyldimethylammonium chloride) (PDDA). Among both the particles, SBA‐15‐BTSA‐PDDA had a higher surface area (10 times), greater pore volume (three times), and better release percentage (two times) than ZnO‐BTSA‐PDDA. Moreover, the surface charge of the SBA‐15‐BTSA‐PDDA exhibits better stability in the dispersive medium; it was considered for electro‐co‐deposition. The surface and cross‐sectional morphology confirmed the incorporation of particles into the zinc matrix. The electrochemical analysis showed that the Zn‐SBA‐15‐BTSA‐PDDA exhibits improved corrosion inhibition performance compared to the pure Zn coating. In the EIS analysis, the Zn‐SBA‐15‐BTSA‐PDDA was immersed for 168 h with a scribe (scratch). It shows superior corrosion inhibition with a self‐healing efficiency of 87%. The accelerated exposure study of the coating using a salt spray chamber confirmed that Zn‐SBA‐15‐BTSA‐PDDA exhibited a synergistic performance in terms of corrosion inhibition and self‐healing action for advanced corrosion protection.

In this study, we systematically investigated the anomalous Nernst effect (ANE) in (Fe 50 Co 50 ) 1‐ x Pt x thin films deposited on rigid quartz and flexible polycarbonate substrates, highlighting significant quantitative improvements compared to conventional ferromagnetic alloys. By carefully tuning the Pt composition, we achieved notable ratios in the anomalous Nernst coefficient ( S ANE ) and transverse thermoelectric constant ( α xy ), yielding a | α xy |/| σ xy | ratio close to the well‐known k B /2e benchmark observed in topological magnets. The S ANE magnitude exhibited a significant fourfold enhancement, increasing from 0.57 µV/K for the Pt‐free sample to around 2.4 µV/K at x = 22.5%. Furthermore, we illustrated how our films achieve ANE sensitivities around 0.19 μm·A −1 , comparable to leading materials. Our results underscore a promising new avenue by demonstrating that even structurally disordered or weakly ordered systems can exhibit significant Berry curvature‐related transport effects traditionally associated with crystalline lattices. This not only highlights the quantitative strength of our approach but also its practical versatility, as these films can be deposited on flexible substrates at room temperature. Our work presents a novel contribution to the field of spin caloritronics, exploring underinvestigated territory in structurally disordered magnetic materials, and paving the way for future flexible ANE devices.

Smart windows capable of electrically regulating light and heat offer an effective approach to reducing energy consumption while maintaining visual privacy. However, conventional smart windows are typically limited to binary switching between transparent and opaque states. Here, we develop a polymer‐dispersed oblique helicoidal cholesteric liquid crystal (PD‐Ch OH ‐LC) system that enables electrically driven and reversible switching among transmission, reflection, and scattering modes. The device is fabricated by doping a Ch OH ‐LC mixture with ultraviolet (UV) polymerizable monomers, which undergo polymerization and phase separation under irradiation with 365 nm UV light, endowing the system with mechanical stability. Particularly, the PD‐Ch OH ‐LC device exhibits electrically tunable reflection within a wide temperature range including room temperature, allowing dynamic modulation of color across the full visible spectrum. The multifunctional state switching and flexibility of this smart window demonstrate great potential for applications in smart building and automotive windows.

Zein, a hydrophobic protein derived from corn, presents significant potential as a sustainable bioadhesive alternative to conventional petroleum‐based adhesives. This study explores a sustainable method for extracting and purifying zein from corn gluten meal (CGM), followed by a comparative analysis of raw, purified, and commercial zein. The samples were characterized by thermal (thermogravimetric analysis [TGA] and differential scanning calorimetry [DSC]), spectroscopic (Fourier transform infrared spectroscopy [FTIR] and ultraviolet–visible [UV–Vis] spectroscopy), and morphological (hot‐stage optical microscopy) analyses. Raw zein was extracted using aqueous ethanol and purified by anti‐solvent dialysis to remove impurities, including carotenoids. For adhesive formulation, raw zein was combined with sodium dodecyl sulfate (SDS) and cast into films, which were then modified by immersion in FeCl 3 or CaCl 2 solutions. The resulting zein‐based adhesives (Zein/SDS/Fe and Zein/SDS/Ca) were tested on various substrates (polypropylene, glass, wood, and cardboard) through shear tests. The adhesives demonstrated competitive bonding performance, particularly Zein/SDS/Fe formulation on wood substrate, confirming their potential for practical applications. In addition, the material exhibits characteristics that may contribute to sustainability and cost‐effectiveness, including the use of a renewable agroindustrial byproduct as feedstock, a high extraction yield (~90%), a simple and potentially scalable processing route, ethanol recovery and reuse, and relatively mild processing conditions.

Barium titanate (BT) and barium–strontium titanate (BST) are key ferroelectric ceramics for electronics and power electronics applications, where complex geometries can significantly enhance functional performance. Binder jetting (BJ) powder bed additive manufacturing offers a promising route to fabricate such architectures, provided that powder properties are carefully tailored. In BJ, powder flowability and binder compatibility are critical and often antagonistic parameters. In this work, commercial BT and BST powders are systematically characterized with respect to particle size distribution, flowability, and binder interaction. Granulated BST powders (D50 ∼20 µm) exhibit excellent flowability (Hausner index H ∼1.3) but poor binder affinity, leading to fragile green bodies. Conversely, fine nongranulated powders (D50 ≈ 4.4 µm) show strong binder interaction but poor flowability (H ∼2.3), limiting powder bed stability. Two strategies are investigated to overcome these limitations: (i) impregnation of granulated powders with an aqueous binder and (ii) addition of fumed silica (0.5–2 wt%) to fine powders. Binder impregnation increases BST green density up to 31.3%, while 1.25 wt% SiO 2 improved BT flowability ( H ∼1.9) and enabled stable green parts with green densities up to 32.6%. This work demonstrates the critical interplay between powder flowability and binder compatibility in BJ for complex dielectric ceramics.

The growing demand for sustainable materials in additive manufacturing (AM) has prompted the investigation of bio‐based substitutes for petroleum‐derived resins. Among AM processes, digital light processing (DLP) offers high precision but relies on nonbiodegradable photopolymers. This study introduces a UV‐curable acrylate resin formulated from Azadirachta indica (neem) oil, a renewable, antimicrobial material, for DLP 3D printing. Neem oil underwent epoxidation via a methyltrioxorhenium (MTO)‐catalyzed biphasic system at ambient temperature, followed by acrylation to produce a DLP‐compatible bio resin. The resin demonstrated favorable photocuring behavior and facilitated high‐resolution, defect‐free printing. Comprehensive characterization demonstrated excellent mechanical strength, flexibility, and rheological stability. Biological assessments validated superior cytocompatibility, hemocompatibility, and controlled hydrolytic breakdown. This is, to our knowledge, the first study on MTO‐based epoxidation and acrylation of neem oil for DLP 3D printing. The acrylate showed 75% conversion of double bonds and a printable viscosity of 3.6 Pa.s. The printed polymer demonstrates elastic behavior with an ultimate compressive strength of 246.3 ± 42.2 kPa at 52.0% ± 3.9% strain. The material showed excellent cytocompatibility, with more than 95% of NIH‐3T3 cell viability at 24 and 72 h, making it a viable solution for biomedical applications, including implanted devices, wound healing, and anti‐infection coatings.
