The solidification behavior in the Zn molten pool during the LPBF process under the influence of thermoelectric magnetic effects was simulated using a physical model that integrated SMF. The results indicated that the thermal electromagnetic force induced by SMF reached up to 106 N/m3, effectively fragmenting regular Zn columnar dendrites and enhancing heterogeneous nucleation efficiency, thus promoting the columnar-to-equiaxed transition and grain refinement. Consequently, compared to samples printed without SMF assistance, the mechanical anisotropy index of yield strength and elongation in the SMF-assisted LPBF-printed Zn sample was significantly reduced from 18.63% and 16.49% to 2.46% and 2.58%, respectively, while maintaining superior strength-ductility synergy. This nearly isotropic mechanical behavior primarily resulted from well-modulated grain characteristics that served as a sustainable source of strength-ductility by coordinating grain boundary strengthening and dislocation strengthening mechanisms, as well as utilizing balanced basal <a> slip and pyramidal <c+a> slip deformation modes. These findings can provide a microstructure manipulation strategy to effectively mitigate the mechanical anisotropy of laser powder bed fusion additively manufactured Zn-based materials for biomedical applications.","PeriodicalId":16154,"journal":{"name":"Journal of Materials Science & Technology","volume":"23 1","pages":""},"PeriodicalIF":10.9,"publicationDate":"2025-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145141520","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}

For example, carbon can exist as graphite (soft, conductive) or diamond (hard, insulating). Computational methods that can predict these polymorphs are vital in materials science, which help understand stability relationships, guide synthesis efforts, and discover new materials with desired properties without extensive trial-and-error experimentation. However, effective crystal structure prediction (CSP) algorithms for inorganic polymorph structures remain limited. ParetoCSP2 is proposed, a multi-objective genetic algorithm for polymorphism CSP that incorporates an adaptive space group diversity control technique and the sustainable age-fitness Pareto optimized evolutionary mechanism, preventing over-representation of any single space group in the population guided by a neural network interatomic potential. Using an improved population initialization method and performing iterative structure relaxation, ParetoCSP2 not only alleviates premature convergence but also achieves improved convergence speed. These results show that ParetoCSP2 achieves excellent performance in polymorphism prediction, including a nearly perfect space group and structural similarity accuracy for formulas with two polymorphs but with the same number of unit cell atoms. Evaluated on a benchmark dataset, it outperforms baseline algorithms by factors of 2.46-8.62 for these accuracies and improves by 44.8-87.04% across key performance metrics for regular CSP.

Although histological examination of liver tissue biopsies continues to serve as the most reliable diagnostic approach, the development of precise detection methods remains crucial for enabling timely therapeutic interventions and improving patient management. Recent advances in fluorescent probes have transformed the detection of liver fibrosis, enabling real-time, non-invasive visualization of biomarkers and microenvironmental changes. Based on its design strategy, targeted objects and functional characteristics, this review systematically classifies state-of-the-art fluorescent probes into five categories: probes directly targeting liver fibrosis markers, enzyme-activated probes, microenvironment-responsive probes, intracellular targeting probes, and multifunctional theranostic probes. Among them, near-infrared II (NIR-II, 1000-1700 nm) imaging and genetically encoded probes boost molecular precision and resolution, yet clinical application faces challenges from limited tissue penetration and poor biocompatibility. Consequently, future research in this field will concentrate on the development of NIR II probes, the discovery of biomarkers in biofluids, and the design of new therapeutic interventions. By elucidating design principles and applications, this review aims to bridge the gap between molecular innovation and clinical practice, ultimately advancing precision medicine for liver fibrosis.","PeriodicalId":87,"journal":{"name":"Materials Horizons","volume":" ","pages":""},"PeriodicalIF":10.7,"publicationDate":"2025-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145147248","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we present a photoregulated assembly-disassembly dynamic system based on synthetic building blocks composed of an azobenzene moiety and an organelle membrane-targeting unit. Upon localization to the organelle membrane, these photoresponsive monomers self-assemble into supramolecular fibrils that interact multivalently with the membrane. UV irradiation (365 nm) induces trans-to-cis isomerization of the azobenzene units, resulting in a morphological transition from fibrillar to amorphous assemblies with reduced membrane affinity. Subsequent exposure to visible light (450 nm) restores the fibrillar state. This reversible assembly-disassembly process enables dynamic control of the membrane binding strength, ultimately disrupting organelle membrane integrity through cyclic weakening and strengthening of supramolecular interactions. Our findings highlight the potential of light-driven, multivalent self-assembly as a strategy for modulating subcellular structures and regulating cellular fate with high spatial and temporal precision.","PeriodicalId":53,"journal":{"name":"Nano Letters","volume":"100 1","pages":""},"PeriodicalIF":10.8,"publicationDate":"2025-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145140475","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}

In this study, the gas-atomized Zr55Cu30Al10Ni5 (at.%) metallic glass powder was heated by differential scanning calorimetry (DSC) and nanocalorimetry to investigate the crystallization behaviors at rates spanning five orders of magnitude. At a slow heating rate, CuZr2 and NiZr2 are identified as the primary crystallization phases. Upon rapid heating, nevertheless, crystallization predominantly produces various Cu-Zr-based intermetallic compounds, including Cu5Zr, CuZr2 and Cu10Zr7 while the formation of NiZr2 is limited. Based on the crystallization kinetics and microstructure evolution, the nucleation and crystal growth rates between Tg and Tm were calculated using classical nucleation theory and an improved Wilson-Frenkel model. Accordingly, the critical temperature for the decoupling of diffusivity and viscosity is 730.9 K. The contact angle for nucleation is estimated to be 23.5° with a maximum nucleation rate occurring at 0.72 Tm. The maximum crystal growth rate is determined to be 2.3 × 10-5 m/s at 0.95 Tm. The roles of nucleation and crystal growth in tailoring the mechanical properties of the powder were further revealed through the single-powder compression method. Slow heating facilitates the formation of nanocrystals due to the ultrahigh nucleation rate but low growth rate, resulting in exceptionally high microhardness but limited compressive strength and toughness. At rapid heating, in contrast, the formation of Cu-Zr-based crystals leads to the reduction of hardness while compressive fracture strength peaks at 2,000 K/s with increased toughness.","PeriodicalId":344,"journal":{"name":"Journal of Alloys and Compounds","volume":"91 1","pages":""},"PeriodicalIF":6.2,"publicationDate":"2025-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145140620","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
