However, a lack of comprehensive theoretical understanding of LSPR limits its full exploitation in photocatalytic systems. In this study, we propose a strategy to regulate the hyper-release of LSPR in S-scheme heterojunctions. By leveraging Mie-Gans theory and hot electron transfer kinetics, we achieve a finely tuned balance between the trapping and release of LSPR-induced hot electrons through defect concentration optimization. Using femtosecond transient absorption spectroscopy, we distinguish LSPR-related signals in the infrared region and quantify the hot electron transfer efficiency in the heterojunction, providing compelling evidence for the hyper-release mechanism. An S-scheme heterojunction between monoclinic W18O49 and cubic CdS was constructed via an in-situ growth strategy without the use of noble metal co-catalysts, resulting in a composite that achieves an outstanding photocatalytic hydrogen evolution rate of 3125 μmol h−1 g−1, outperforming conventional designs. This work not only offers fresh insights into the electron dynamics of the LSPR effect but also sets a benchmark for designing plasmonic-semiconductor hybrid systems, opening new horizons for sustainable energy conversion technologies.","PeriodicalId":16154,"journal":{"name":"Journal of Materials Science & Technology","volume":"3 1","pages":""},"PeriodicalIF":10.9,"publicationDate":"2025-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144176870","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Combined with the concept of bionics, this paper utilized a bio-inspired muscle fascicle-like fiber bundle structure to improve the toughness of Cf/Si3N4 composites. Li2O-Al2O3-SiO2 (LAS) was chosen as the raw material to grow SiC nanowires (SiCnw) in situ on the surface of carbon fibers. Subsequently, in the sintering process, the fibers were encapsulated with the Li-O-Al system to form a continuous nanolayer structure. Notably, the carbon fibers wrapped by the nanolayers formed a muscle fascicle-like fiber bundle structure. Compared with single fibers, the muscle fascicle-like structure has stronger toughness. When subjected to external forces, the strong toughness makes it less likely to break during the fracture process, resulting in a more pronounced pull-out. Muscle fascicle-like structures utilize this pull-out mechanism to absorb a large amount of fracture energy, resulting in a 24.5% increase in fracture toughness and a 98.4% improvement in work of fracture. This suggests that connecting the fibers into a fiber bundle structure through the intermediate phase can effectively exert the energy absorption mechanism, which provides a new idea to improve the mechanical properties of fiber-toughened composites.","PeriodicalId":16154,"journal":{"name":"Journal of Materials Science & Technology","volume":"48 1","pages":""},"PeriodicalIF":10.9,"publicationDate":"2025-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144176872","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results showed that the ODS AlCoCrFeNi2.1 composite coatings exhibited better oxidation resistance than the conventional NiCoCrAlY coatings and some other high-entropy alloy (HEA) coatings at 1000 and 1100°C. This was because Y2Hf2O7 nanoparticles decreased the thermally-grown oxide (TGO) growth rate and thermal expansion mismatch stresses, and increased the coating/TGO interfacial toughness. The composite coating rapidly failed after only 200 h of oxidation at 1200°C, primarily due to the formation of coarse Al2Y4O9 oxide aggregates within the TGO, which caused the rapid transport of Fe, Cr, Hf, Y, Al, and O atoms. Moreover, the formation of Y2Hf2O7 nanoparticles within the composite coating was induced by regulating the Marangoni convection intensity in the melt pool during HSLC.

However, the confrontations among the dielectric constant (εr), near-zero temperature coefficient of resonant frequency (TCF), and quality factor (Q × f) remain key challenges in high-performance dielectric ceramics. To leverage the trade-off conflicts, using dual-phase perovskite-based dielectric ceramic composites could be a potentially ideal solution. Unfortunately, the selected ions are hard to be doped into the perovskite phase due to the sintering temperature disparity of the two phases, thereby significantly impacting the modification effect. In this study, a “wedge” strategy was employed in a MgTiO3-CaTiO3 dual-phase dielectric ceramic composite by using Ce as an auxiliary dopant to realize the main Hf doping in the CaTiO3 phase due to the lattice distortion. This strategy also harmonizes the confrontation of the sintering temperature disparity between the two components of CaTiO3 and MgTiO3. The Hf4+ doping level of as high as 40 mol.% with a reduced sintering temperature of over 200 °C was successfully achieved by using this “wedge” strategy. Most importantly, the trade-off conflicts among the εr, near-zero TCF, and Q × f have been considerably reduced and harmonized due to the successful introduction of a high dosage of Hf dopant in the CaTiO3 phase without sacrificing the intact structure of MgTiO3. This strategy not only sheds light on manufacturing high-performance dual-phase dielectric ceramics with trade-off conflicts of properties but also provides an innovative pathway to address the challenge of mismatch of sintering temperature for selective ion doping in multiple-phase ceramic composites.","PeriodicalId":16154,"journal":{"name":"Journal of Materials Science & Technology","volume":"41 1","pages":""},"PeriodicalIF":10.9,"publicationDate":"2025-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144176869","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study identified that RIS induced the nucleation of Ni₃Si precipitates from Ni-Si clusters in the irradiated Ni-based alloys, which is considered a significant contributor to irradiation hardening in stainless steel. Atomic probe tomography (APT) analysis revealed Ni enrichment on both sides of the dislocation loop edges, forming a \"W-shaped\" profile. Meanwhile, Si accumulated along the edge, inhibiting loop growth and leading to the formation of shadows. Molecular dynamics (MD) simulations confirmed the mechanism of this enrichment distribution. With increasing irradiation dose, Ni₃Si nucleates at loop edges and coarsens by absorbing nearby Si atoms, ultimately resulting in the dissolution of the loop. This RIS at dislocation loops results in a Si-depleted matrix, stabilizing the nucleation of CrMo-enriched M₂C carbides and newly formed Frank loops. Meanwhile, four Frank loop (FL) variants were found to have anisotropic behavior. Scanning transmission electron microscopy (STEM) characterization across several crystal orientations revealed that the highest density of Frank loops occurred in the variant perpendicular to the crystal orientation. MD simulations indicated a distinct increase in the formation energy of the four variants under compressive stress, highlighting the influence of stress from ion penetration on Frank loop nucleation. These findings provide valuable insights into the evolution of precipitates and quantitative analysis of dislocation loops in Ni-based alloys.","PeriodicalId":16154,"journal":{"name":"Journal of Materials Science & Technology","volume":"58 1","pages":""},"PeriodicalIF":10.9,"publicationDate":"2025-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144176873","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thermal expansion behavior analysis revealed that the expanded coefficient of the diffused magnets was significantly reduced. A binary TbMg low-melting-point alloy diffusion source was innovatively designed, and microstructural investigations demonstrated that Mg incorporation effectively suppresses the formation of surface anti core-shell structures during the diffusion process, achieving an extraordinary coercivity enhancement of 10.17 kOe. Beyond magnetic performance improvements, electrochemical experiments confirmed substantial corrosion resistance enhancement in the modified magnets. Consequently, the developed magnet simultaneously integrates three critical advantages: reduced thermal expansion coefficient, elevated coercivity, and enhanced corrosion resistance.
