To study the structural damage behavior of pure-Al under various shock wave profiles, this paper investigates the target using a light gas gun-driven density gradient material and a homogeneous material. It also conducts structural characterization and failure analysis of the postmortem target. The results indicate that spall strength increases with peak stress. At a strain rate of 103 s−1, the spall strength of the gradient material (approximately 0.502 GPa) is significantly higher than that of the homogeneous material (about 0.157 GPa). This difference is attributed to the temperature softening effect in the homogeneous material. The peak stress of the gradient material impacting pure Al is higher, leading to an increase in small-angle grain boundaries and a phenomenon of grain refinement. Here, the structural damage is primarily influenced by stress effects, resulting in higher spall strength. In contrast, the homogeneous material impacting pure Al exhibits a notable temperature rise, which significantly affects structural damage, making it more susceptible to the formation of pores and cracks, thus resulting in lower spall strength. Furthermore, there are differences in pore morphology under various wave regimes: the pores in the gradient material are elliptical, with the long axis perpendicular to the impact direction, while the pores in the homogeneous material are irregularly shaped. Additionally, the gradient material exhibits multiple spallation surfaces, whereas the homogeneous material shows only one spallation surface. By explaining the damage mechanisms of pure Al under different wave systems, this study aims to provide insights and guidance on the spallation behavior of aluminum matrix composites under complex conditions. © 2025, The Authors.

Although 2D transition-metal carbides (MXenes) are usually synthesized by selective etching and chemical vapor deposition approaches, they are limited by the slow reaction kinetics, resulting in their continuous production challenging. Here, we demonstrate a bubbling chemical vapor growth (BCVG) method to continuously produce Cl-terminated MXenes by the reaction of CH4 and TiCl4 chemical bubbles with titanium powder in a molten salt. In the molten reaction system, titanium powder would effectively react with TiCl4 to form highly active [TiCl6]y– with low Ti[sbnd]Cl bond dissociation energies. The multivalent [TiCl6]y– could efficiently incorporate the carbon species from CH4 to form [Ti6CCl18] clusters on the surface of bubbles in a low energy barrier, efficiently promoting the reaction kinetics. Subsequently, Cl-terminated MXenes were produced based on the following condensation reaction of [Ti6CCl18] clusters. The resultant MXene (Ti2CClx) exhibits an expanded structure with strong interfacial polarization between its basal planes and the polymer matrix, delivering a good electromagnetic wave absorption performance with a minimum reflection loss (RLmin) value of –52.2 dB at a thin thickness of 2.84 mm. © 2025 Elsevier Ltd

This study investigates the microstructure, mechanical properties, and shape memory behavior of a series of (84-x) Cu-12Al-4Ni-xAg (x = 0, 4, 8, 12 wt%) alloys with varying Ag contents. The alloys predominantly exhibited martensitic phases: 18R and 2H, with the 18R phase becoming more prevalent as Ag was introduced. The formation of the Ag2Al phase and microstructural refinement contributed to significant improvements in mechanical properties. Notably, the alloy with 8 wt% Ag (x = 8) exhibited peak compressive strength of 947.1 MPa, the compressive strain of 14.1 %. Additionally, the inclusion of Ag enhanced the shape memory effect of the alloys, with the x = 8 alloy demonstrating a reversible strain of 4.7 % upon heating after an 8 % pre-strain. © 2025 Elsevier B.V.

Microalloying with rare earth elements is an effective method to improve the corrosion resistance of Cu–Ni alloys. The study of the effect of different rare earth elements on the corrosion resistance and corrosion behavior is significant for the optimization of Cu–Ni alloy composition. In this paper, the effect of La and Ce on the corrosion behavior of B10 alloy in 3.5 wt% NaCl solution was investigated separately, utilizing both electrochemical techniques and surface characterization methods. The results indicate that B10-0.1 wt% La alloy and B10-0.1 wt% Ce alloy have better corrosion resistance performance compared to Cu–10Ni alloy in NaCl solution. The better corrosion resistance performance of the B10-0.1 wt% La and B10-0.1 wt% Ce alloy could be mainly attributed to the preferential deposition of rare-earth oxides that promotes heterogeneous nucleation of the passive film. Furthermore, the deposition degree of La 2 O 3 is greater than that of Ce 2 O 3 during the early stage of immersion which leads to the superior corrosion resistance of the B10-0.1 wt% La alloy.

Premature perovskite films rapidly form at the FAI/PbI 2 interface, inhibiting further reactions between FAI and PbI 2 during the fabrication of perovskite films via the evaporating-spraying hybrid method according to our previous research. In this research, triphenylphosphine oxide (TPPO) was proved to be an effective coordinator that reduces the reaction rate between FAI and PbI 2 at the initial stage, which can be attributed to the hydrogen (H) bonds between FA + and TPPO, and coordinate bonds between TPPO and PbI 2 . Additionally, the quality of perovskite films improved significantly: the trap state density decreased from 1.6 × 10 18 to 3.17 × 10 17 cm −3 , while the crystal size increased from 740 to 940 nm. The champion perovskite device achieved a remarkable efficiency of 20.93% (0.09 cm 2 ) and 16.75% (63.7 cm 2 ), marking one of the highest reported results for the evaporating-spraying hybrid method. Moreover, the perovskite solar cells retained over 80% of their initial performances after 600 h of storage at 60 °C in a nitrogen environment without encapsulation. It also maintained approximately 90% of its initial performance after continuous illumination at 25 °C for 1400 h under the same conditions.

The recently emerged chloride solid electrolytes have garnered significant attention due to their superior ionic conductivity, wide electrochemical stability window, and exceptional compatibility with high-voltage oxide cathodes. Nevertheless, the currently cost-effective Zr-based chloride solid electrolytes face significant challenges, including low ionic conductivity and poor moisture stability. Herein, a versatile Zn2+-doped Zr-based chloride electrolyte is presented, designed to meet the aforementioned requirements. The optimized Li2.4Zr0.8Zn0.2Cl6 exhibits an improved ionic conductivity of 1.13 mS cm−1 at 30 °C. Simultaneously, the Li2.4Zr0.8Zn0.2Cl6 also demonstrates impressive moisture stability, maintaining its structural integrity after exposure to humid air. The mechanism underlying the enhanced moisture stability of Li2.4Zr0.8Zn0.2Cl6 is further elucidated by density functional theory calculations. Most notably, whether coupled with LiCoO2 or LiNi0.8Mn0.1Co0.1O2 cathodes, Li2.4Zr0.8Zn0.2Cl6-based all-solid-state batteries demonstrate exceptional cycling stability and rate performance. This high ionic conduction and moisture-resistant chloride electrolyte holds great promise for significantly advancing the commercialization of all-solid-state lithium batteries. © 2025 Wiley-VCH GmbH.

Chronic wounds have emerged as a formidable challenge in diabetes management, leading to high morbidity and mortality. The diabetic wound healing is often impaired due to recurrent bacterial infections, excessive reactive oxygen species (ROS), and severe hypoxia. Thus, we developed a multifunctional nanoplatform that exhibited remarkable antibacterial activity, ROS scavenging and oxygen-carrying properties. Metal-phenol network (MPN) as core material was synthesized by assembling tannic acid (TA) with Fe2⁺ via coordination and hydrophobic interactions. Subsequently, hemoglobin (Hb) was decorated onto MPN surface through cation-π interactions. MPN protected Hb against oxidation and preserved its physiological function, facilitating oxygen transport. Moreover, MPN-Hb displayed robust and broad-spectrum antioxidant activity that can effectively scavenge ROS and reactive nitrogen species. Under near-infrared (NIR) irradiation, MPN-Hb demonstrated excellent bactericidal activity against Escherichia coli (E. coli) and Staphylococcus aureus (S. aureus), effectively eradicated biofilms through hyperthermia. In vivo studies have shown that MPN-Hb with good biocompatibility could effectively eliminate bacteria at the wound site, mitigate the inflammatory response, and promote collagen deposition and angiogenesis, thereby accelerating wound healing. Overall, this multifunctional nanoplatform offers a straightforward, safe, and efficient therapeutic strategy for treating chronic diabetic wounds. © 2025 Elsevier B.V.
