Aqueous zinc (Zn) metal batteries (AZBs) have emerged as highly promising candidates for large-scale energy storage systems because of their inherent safety and cost-effectiveness. However, their practical implementation remains constrained by parasitic side reactions and uncontrolled dendrite growth at the metallic Zn anode. Herein, a microenvironment-controlled additive strategy is proposed via employing phytic acid-functionalized montmorillonite (MPA) nanosheets as electrolyte additives for highly durable AZBs. The MPA nanosheets spontaneously assemble onto the surface of the Zn anode through interfacial self-adsorption, effectively suppressing parasitic reactions. Moreover, the regulation of interfacial chemistry enhances the zincophilic characteristic, enabling precise modulation of Zn 2+ flux distribution and directing homogeneous Zn electrodeposition through spatially controlled ion coordination. As a result, the Zn||Zn symmetric cell with the MPA additives achieves a stable cycle for over 2800 h at 2 mA cm −2 . The assembled Zn||VO 2 full cell within the modified electrolyte maintains exceptional cycling stability of 89.5% after 1000 cycles. This work presents a facile and efficient microenvironment-regulated additive strategy for homogeneous Zn deposition, aimed at achieving highly reversible AZBs.

Purpose This research sought to investigate the impact and underlying mechanisms of growth hormone (GH) on atherosclerosis (AS) based on the analysis of single-cell RNA sequencing (scRNA-seq) data. Methods We analyzed the impact of GH on arterial vascular smooth muscle cells (VSMCs) by utilizing scRNA-seq data obtained from both atherosclerotic and healthy vascular tissues in mice. AS was induced in C57BL/6 and ApoE −/− mice through hypophysectomy performed via the parapharyngeal approach, followed by a high-fat diet (HFD), resulting in the C57-Hx and ApoE −/− -Hx models. AS was evaluated by measuring arterial lipid deposition, plaque progression, collagen loss, vascular inflammation, and oxidative stress. Serum metabolite alterations were assessed using liquid chromatography-mass spectrometry (LC-MS). RNA sequencing was employed to examine the underlying mechanisms of GH in the context of AS treatment, with findings further confirmed through western blot analysis. In vitro experiments involved treating VSMCs with oxidized low-density lipoprotein (ox-LDL) to simulate atherosclerotic injury. The formation of foam cells was evaluated by measuring lipid accumulation, inflammatory responses, apoptosis, and the expression levels of foam cell-related markers. Finally, the PI3K/AKT inhibitor LY294002 confirmed that GH alleviates AS via the PI3K/AKT signaling pathway. Results scRNA-seq data analysis showed that growth hormone signaling was reduced in VSMCs of atherosclerotic arteries. HFD led to elevated levels of serum total cholesterol (TC), triglycerides (TGs), and low-density lipoprotein cholesterol (LDL-C), accompanied by increased lipid deposition, inflammatory responses, and oxidative stress. In contrast, high-density lipoprotein cholesterol (HDL-C) and insulin-like growth factor 1 (IGF-1) levels were lower in C57-Hx mice. GH treatment improved HFD-induced AS in ApoE −/− -Hx mice. LC-MS analysis revealed that GH altered lipid metabolism in serum samples from C57-sham, C57-Hx, ApoE −/− -Hx, and ApoE −/− -Hx-GH(3) mice. GH maintained lipid balance by increasing 1-palmitoyl-2-oleoyl-sn-glycerol-3-phosphocholine (POPC), PE-NMe2(18:1(9z)/18:1(9z)) (DMPE), and 4-chloro-2-nitrobenzylalcohol levels and decreasing 1-heptadecanoyl-sn-glycerol-3-phosphocholine. RNA sequencing showed significant gene expression differences in the aortas of C57-sham and C57-Hx mice. Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis revealed that GH inhibited the progression of AS by modulating the phosphatidylinositol 3-kinase/protein kinase B (PI3K/AKT) signaling pathway, a finding that was validated through western blotting. Further in vitro studies demonstrated that GH exerted protective effects on VSMCs against ox-LDL-induced damage through activation of the PI3K/AKT pathway, as evidenced by experiments using the specific PI3K inhibitor LY294002. Conclusion GH alleviates the development of AS through the activation of the PI3K/AKT pathway. The findings of this research emphasize the therapeutic potential of GH in inhibiting AS and highlight the importance of the PI3K/AKT pathway as a promising target for clinical intervention.

The design of dual-mode remediation platforms using flexible metal–organic frameworks (MOFs) to synergize superhydrophobicity and broadband photothermal activity remains a fundamental challenge for programmable solar-driven oil/water separation in spill remediation. A cactus-inspired nanoneedle-architected CuTCNQ MOF (TCNQ = tetracyanoquinodimethane) is developed through bandgap engineering and self-assembly, synergizing intrinsic superhydrophobicity with a narrow bandgap ( E g = 0.36 eV). The passive CuTCNQ@CM membrane achieves gravity-driven oil/water separation (99.53 ± 0.29% efficiency, 84.22 ± 3.82 kL·m −2 ·h −1 flux), retaining 98.26% performance after 20 cyclic separation tests, where ultralong 1D nanostructures amplify surface roughness and capillary forces through synergistic wettability enhancement and separation kinetics optimization. In parallel, the active CuTCNQ@PU system exhibits 98.96% broadband solar absorption (200–2500 nm) and a high solar-thermal conversion efficiency (STCE) of 93.64%, rapidly heating to 90.6 °C under 1-sun irradiation to reduce crude oil viscosity by 98.93%, enabling ultrafast adsorption (84.1 ± 2.3 g·g −1 capacity, 436.7 ± 23.5 g·g −1 ·min −1 rate). The design pioneers dual-mode superhydrophobicity-bandgap MOFs by unifying passive/active functionalities through nanostructuring. The scalable synthesis, combined with sunlight-triggered adsorption, delivers an uninterrupted remediation platform–passively treating bulk spills and actively addressing viscous residues via light-controlled synergy, advancing energy-efficient environmental technologies.

Plant pests pose a significant threat to agricultural productivity, while chemical pesticides cause environmental concerns. In this study, plasma-activated mist (PAM) generated by mixing water mist with plasma-activated gas could effectively inactivate Myzus persicae adults and Helicoverpa armigera larvae and eggs. PAM treatment induced an increase in oxidative stress markers, such as malondialdehyde levels and superoxide dismutase activities in pests. The reactive species in PAM left only trace nitrate residues on leaves. Furthermore, the 50-day consecutive PAM treatment had little effects on the growth and appearance of the Malabar spinach. Therefore, the PAM supplied a promising, effective, and environmentally-friendly alternative for large-scale applications in agricultural fields.

MAX phase ceramics, as a family of ternary layered ceramics, have received a lot of attention in the past decade due to their potential as precursors for two-dimensional transition metal carbides. However, due to complex multi-component metallurgical reactions, multicomponent MAX phase ceramics have always faced difficulties in purification and homogenization. This paper identifies a new strategy for synthesizing multicomponent MAX phase ceramics that can eliminate these synthesis difficulties. This path utilizes low-temperature (below 1000°C) stable Ti 2 AlC and carbide powder as initial materials to simplify complex multi-component reactions into a one-step reaction, successfully achieving high purity and precise doping ratio. As an example, four novel doped MAX phase ceramics, Ti 2 MAlC 2 (M = Nb, Ta, W) and Ti 2 HEAlC 2 (HE = 1/7Ti, 1/7V, 1/7Zr, 1/7Nb, 1/7Hf, 1/7Ta, 1/7 W) were successfully synthesized using this method. This dynamic-based design, on one hand, simplifies the reaction mechanism to make purification easier, and on the other hand, the concentrated release of entropy during the reaction process promotes phase transition and related element homogenization.

Herein, a novel sunlight-independent tribocatalytic system with efficient friction energy harvesting capability is proposed. This system demonstrates enhanced tribocatalytic performance of cerium oxide (CeO 2 ) nanoparticles driven by the friction between Cu coated on the glass beaker bottom and a Teflon (PTFE) magnetic disk. An apparent rate constant of 0.045 min −1 was achieved for methylene blue (MB) degradation, representing a 2.7-fold improvement over the CeO 2 @glass/PTFE system (0.01682 min −1 ). Notably, the system achieved > 90% degradation efficiency for high-concentration MB solutions (40 mg/L), surpassing the performance of previously reported tribocatalytic systems. Through multiscale tribo-interface characterization and radical trapping experiments, the synergistic catalytic mechanism was elucidated: Friction-induced charge carriers in CeO 2 are efficiently transferred via the interfacial electronic effects of the Cu/PTFE friction couple and the active surface with Ce 3+ /Ce 4+ redox couples. Electron paramagnetic resonance analysis confirmed that Cu coating modification on the surface of the beaker bottom enhanced hydroxyl radical (·OH) yield by 2.3-fold compared to glass, enabling complete pollutant degradation through hole (h + )-dominated oxidation pathways. This work transcends conventional catalyst modification strategies, establishing a new paradigm for interface engineering in mechano-chemical energy conversion systems.

Aluminum borate whiskers (ABOws) have been widely utilized as a secondary phase for fabricating ceramic composites. The morphology and thermal stability of ABOws play a critical role in achieving their optimal performance. In this study, two precursor powders were synthesized via chemical precipitation and mechanical mixing, followed by the induction of a solid–liquid reaction at elevated temperatures to form ABOws. For ABOws prepared from chemically precipitated powder, a metastable intermediate Al 2.1 B 0.9 O 4.5 phase was first formed at 850°C, which subsequently transformed to Al 4 B 2 O 9 at 1000°C and further evolved into needle-like Al 18 B 4 O 33 with high aspect ratio at 1150°C. In contrast, for ABOws prepared via mechanically mixed powder, the formation of Al 4 B 2 O 9 began at 850°C, and it fully converted to rod-like Al 18 B 4 O 33 at 1150°C. The morphology differences of those two types of ABOws were ascribed to their different nucleation routines. Homogenous and heterogeneous nucleation occurred in the chemically precipitated amorphous and mechanically mixed powders, respectively, leading to the formation of ABOws with different morphologies. The two types of ABOws demonstrated phase composition stability up to 1400°C. However, pronounced morphological changes were observed at 1200°C. These findings offer valuable insights into the microstructure formation process and thermal stability of ABOws with tunable morphologies.

A series of ferrite ceramics with the chemical formula Fe(Cr x Fe 2− x )O 4 ( x = 1.5, 1.6, 1.7, 1.8, 1.9) were synthesized using the solid-state reaction method. Rietveld refinement of the x-ray diffraction patterns confirmed the formation of a pure cubic spinel structure, with the lattice parameters decreasing as the Cr 3+ content ( x ) increased. Raman spectroscopy revealed the splitting of the A 1 g ${{{\mathrm{A}}}_{1{\mathrm{g}}}}$ vibrational mode into two distinct bands at 670 and 710 cm −1 that were attributed to the symmetric stretching vibrations of Fe 2+ –O and Fe 3+ –O bonds, respectively. This supports a mixed spinel-type cation distribution in which Cr 3+ and a fraction of Fe 2+ ions occupy octahedral sites, whereas Fe 3+ and the remaining Fe 2+ ions occupy tetrahedral sites. With increasing chromium content, the dielectric constant and loss tangent both decreased. Magnetic measurements showed a reduction in the remnant magnetization and coercivity. Furthermore, the samples demonstrate behavior that tends toward a superparamagnetic response. This study systematically established the relationship between the Cr/Fe ratio and the resulting structural, dielectric, and magnetic properties, underscoring the important role played by cation distribution in tuning the material properties of these ferrite ceramics.

The present study explores the densification and mechanical properties of novel Al 4 O 4 C ceramics, which are enhanced by the incorporation of Y 2 O 3 additives and the utilization of spark plasma sintering. A significant observation was the presence of a native oxide layer on the surface of the Al 4 O 4 C powder, predominantly composed of Al 2 O 3 . Following sintering at 1723 K, Al 4 O 4 C was established as the primary phase, with Al 2 O 3 and Y 3 Al 5 O 12 (YAG) identified as secondary phases. Comprehensive experimental analysis, complemented by molecular dynamics simulations, revealed the mechanism of YAG on the grain growth behavior of Al 4 O 4 C. The findings demonstrated that an optimal Y 2 O 3 content of 3 wt% resulted in a maximum flexural strength of 272 MPa, a fracture toughness of 2.01 MPa·m 1/2 , and a Vickers hardness of 15.1 GPa. This research offers valuable insights into the densification process and the enhanced mechanical properties of ternary carbides, paving the way for their further applications.

MAX phases can benefit from high-entropy (HE) effects to enhance their electromagnetic (EM) wave absorption properties. This study introduces Joule heating-driven ultrafast synthesis (JHUS) for the first time to synthesize the novel HE-MAX phase (Ti 1/5 Nb 1/5 Ta 1/5 Hf 1/5 V 1/5 ) 2 AlC at 1200°C in 20 s. The high-entropy effects, combined with the JHUS, lead to the formation of structural defects within the HE-MAX phase, such as lattice distortions, dislocations, and point defects. These structural defects play a crucial role in promoting dipole polarization. The high aspect ratio of the layered structure promotes electron transfer and interfacial polarization. These effects result in a significant improvement in EM wave absorption, with a minimum reflection loss of −46.07 dB at 2.7 mm and a 4.08 GHz absorption bandwidth at 1.5 mm. This study demonstrates an efficient and rapid method for synthesizing HE-MAX phases and explores the role of high-entropy engineering in optimizing their EM wave absorption.

Tungstate, with the molecular formula AWO 4 , has attracted widespread attention due to its outstanding applications in various fields. Ba 1- x Sr x WO 4 ( x = 0, 0.2, 0.4, 0.6, and 0.8) ceramics with a single-phase scheelite structure are synthesized by the conventional solid phase reaction method. Their structural stability, micromorphology, and element distribution, thermal and mechanical properties are systematically investigated. The experimental thermal conductivity of all samples is 0.852–1.056 W·m −1 ·K −1 at 1173.15 K. An outstanding advantage of Ba 1- x Sr x WO 4 ceramics is that the coefficient of thermal expansion increases from 7.71 × 10 −6 K −1 ( x = 0) to 10.31 × 10 −6 K −1 ( x = 0.8) at 1173 K, indicating that the doping of Sr ion reduces the system energy during the lattice relaxation process and significantly improves the coefficient of thermal expansion. The thermal conductivity of Ba 1- x Sr x WO 4 ceramics is significantly lower than that of most low thermal conductivity candidate materials, such as Y 2 SiO 5 , SrZrO 3 , and La 2 Zr 2 O 7 . This study lays a foundation for the design of BaWO 4 scheelites with excellent thermal properties, which have high practical application value in the field of thermoelectric conversion and thermal protection.

Monoclinic barium aluminosilicate (celsian) shows application potential owing to its high-temperature resistance, low thermal conductivity, and excellent oxidative reduction properties. Hexacelsian can easily undergo nucleation because of its favorably symmetric crystal structure, resulting in faster precipitation compared to in the case of celsian. This study successfully synthesized celsian Ba 1− x Ca x Al 2 Si 2 O 8 using a two-step sintering method. Ca 2+ doping significantly promoted celsian formation, with each 5% increase in CaO content reducing synthesis temperature by ∼50°C. A nearly pure monoclinic celsian phase (Ba 0.7 Ca 0.3 Al 2 Si 2 O 8 ) was obtained after 3 h of heat treatment at 1300°C, achieving a ∼100°C reduction compared to conventional one-step sintering. Meanwhile, the celsian Ba 1− x Ca x Al 2 Si 2 O 8 prepared by the two-step sintering method exhibits higher bulk density and thermal conductivity compared to the one-step sintering method. And the thermal conductivity decreased progressively with both increasing heat treatment temperature and CaO content, primarily influenced by phase composition and crystalline defects.
