Conventional deproteinized bovine bone grafts, despite their common usage, exhibit limitations in meeting the dual requirements of enhanced primary implant stability and robust osteogenic outcomes, primarily due to the limitations associated with their granular morphology. Here, we introduce a novel biocompatible hydroxyapatite/poly(lactide-co-caprolactone) (HAP/PLCL) composite as a bulky bone augmentation material for MSFE. This material possesses characteristics with high mechanical properties (Young's modulus = ∼1.15 GPa; hardness = ∼0.06 GPa), superior viscoelastic properties (tanδ = 0.130) and considerable osteoconductive potential (bone-to-implant contact improved by 1.6-fold compared with Bio-Oss). The HAP/PLCL bone augmentation composite not only enhances the removal torque for more than 2 times of the primary stability during implantation but also promotes superior osteoimmunological responses, ultimately leading to the early and long-term success of dental implants. The employment of the HAP/PLCL composite is anticipated to improve simultaneous implantation with MSFE, contributing to faster healing and prolonged lifespan of dental implants.</div></div>","PeriodicalId":48517,"journal":{"name":"Materials Today Nano","volume":"30 ","pages":"Article 100624"},"PeriodicalIF":8.2,"publicationDate":"2025-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143860153","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}

Typically, at 600 °C, CNS nano-boxes exhibit a minimum reflection loss (RL_min) of −50.03 dB and an effective absorption bandwidth (EAB) of 5.68 GHz at 2.81 mm, essentially covering the X-band.

Impressively, changing the proportion of dopamine (DA) in the raw materials at the calcination temperature of 700 °C, the as-synthesized samples CNS-700-1 and CNS-700-3 also exhibit low RL_min values of −63.37 [email protected] GHz and −44.85 [email protected] GHz, respectively. The in-situ self-polymerization of DA on the surface of Cu_2-xS successfully constructed a multi-layer interface and provided adsorption sites for Ni²⁺ ions. Finally, through pyrolysis, Ni²⁺ ions were reduced to magnetic Ni nanoparticles, achieving the integration of magnetic and electrical components in the material. The CNS nano-boxes possess a unique multi-layer hollow structure and magnetoelectric coupling properties, which effectively regulate the impedance matching, induce the generation of multiple polarizations, and provide excellent low-frequency response characteristics.

As the substituting Co content or phosphorus source increases Co_xNi_2-xP nanocrystals change from large hollow structure to small solid. Atomic high-angle annular dark-field scanning transmission electron microscopy (HAADF-STEM) image and elemental mapping reveal that Ni and Co atoms are evenly distributed at the tetrahedral and pyramidal sublattices. Co substitution and phosphorus defect are favored to induce ferromagnetic ordering in Co_xNi_2-xP nanocrystals different from the nonmagnetic bulk Co₂P and Ni₂P. By increasing the substituting Co the saturation magnetization (Ms) values increase first and then decrease among which Co_0.36Ni_1.64P shows the largest Ms value of 14.11 memu/g. The nonlinear variation tendency of Co-related magnetism is ascribed to the selective occupancy of Co atoms. Co substituted at tetrahedral site show lower formation energy and low spin state but Co at pyramidal site behave high spin state with larger magnetic moment. Moreover, phosphorus defect can stably exist and induce spin polarization boosting the room-temperature ferromagnetism. The Ms values decrease from 14.39 to 2.87 memu/g by increasing the phosphorus sources. X-ray magnetic circular dichroism (XMCD) indicates the existence of ferromagnetic coupling and the total magnetic moments are reduced by decreasing phosphorus defects.

We propose rapid fabrication of graphene–metal heterojunctions as a key solution to tune the temperature sensitivity of graphene by modifying the Seebeck coefficient.
