Compared to inert scaffolds, bioceramic scaffolds offer superior capabilities such as excellent biocompatibility, bioactivity, suitable mechanical properties, controlled degradation rates, and functionality to meet individual needs, which are essential for enhanced osseointegration and mechanical stability. In addition, they can yield controlled multifunctional therapeutic effects matched to the needs, such as antibacterial or antitumor properties. This study reviews advances in 3D‐printed bioceramic multifunctional scaffolds for BTE. First, 3D printing techniques and a range of bioceramic materials suitable for bioceramic scaffolds are introduced. Notable advances in 3D‐printed bioceramic scaffolds for personalized structural and multifunctional repair are discussed. Finally, the review highlights the challenges faced in the development and clinical application of multifunctional bioceramic scaffolds, discusses future trends, such as the application of modular scaffolds, and points out emerging technologies in this field.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"143 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2025-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144678089","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}

While some methods can control PDT activation in tumors, they may reduce its effectiveness due to incomplete activation. In this study, a stimulus‐responsive nanoparticle is designed using Zr porphyrin carboxylate metal‐organic framework PCN‐224 and a DNA lock modified with Quencher and Apurinic/apyrimidinic sites (PCN‐QADNA). PDT is activated by Apurinic/apyrimidinic endonuclease 1, an endonuclease overexpressed in cancer cells, and further enhanced by positive feedback effect of cellular homeostasis regulation. PCN‐QADNA shows improved biocompatibility, enhanced cellular uptake, and a 93.5% tumor inhibition rate in tumor‐bearing mice after intravenous injection and light exposure, with no significant skin damage. This system enables controllable PDT with positive feedback, selectively targeting cancer cells and minimizing side effects.

Here, a dual‐modulation aqueous electrolyte is designed by incorporating a hydrogen bond acceptor, dimethylacetamide (DMA), and an anion receptor, benzyl alcohol (BA), to simultaneously improve zinc anode reversibility and stabilize the manganese ferrocyanide cathode. DMA disrupts interfacial H‐bond networks via its carbonyl group, hindering proton transport through the Grotthuss mechanism. Meanwhile, BA anchors OTf⁻ anions through hydroxyl‐mediated hydrogen bonding, promoting their selective decomposition into species that form a uniform, electron‐blocking solid electrolyte interphase (SEI) on the zinc surface. This SEI suppresses HER by preventing electron transfer to free water, enabling efficient zinc plating.

Traditional carbon coating strategies are often conducted under high‐temperature (over 700 °C) or oxidative conditions that are not suitable for BP due to its low sublimation temperature (400 °C) and high oxidation susceptibility in air/moisture. In this work, by utilizing self‐catalysis effect of BP, we propose a low‐temperature carbon coating strategy for BP anodes toward high‐stable and high‐capacity lithium storage. The strategy is realized by a two‐step approach including interfacial electrostatic assembly of carbon quantum dots (CQDs) on BP nanosheets, followed by BP self‐catalyzed in situ interfacial cross‐linking of CQDs, forming a continuous carbon layer on BP (BP@CL). DFT calculations reveal that BP self‐catalysis significantly reduces the energy barriers of CQDs cross‐linking reactions, while finite element simulations demonstrate that the carbon layer effectively mitigates lithiation stress of BP@CL (above 51% reduction). The optimized BP@CL composite anode exhibits exceptional cycling stability with 87.3% capacity retention after 500 cycles at 0.2 A g−1, significantly outperforming that of pristine BP. The developed mild carbon coating method with BP self‐catalysis provides a new opportunity for designing advanced BP‐based electrodes in energy storage applications.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"24 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2025-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144678090","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}

Traditional EMI shielding materials predominantly depend on the robust reflective capabilities of highly conductive. However, when these materials are employed in the context of highly integrated and miniaturized electronic devices, there exists an inherent risk of short‐circuiting. To overcome this dilemma, inspired by the structure of bamboo wall, a bicapacitor architecture comprising MXene as polar plates and SiC nanowire (SiCnw) network as a dielectric layer to develop EMI shielding membrane by multiscale co‐construction is proposed. The fabricated MXene/SiCnw membrane demonstrates a remarkable EMI shielding effectiveness of 65.8 dB at a thickness of≈60 µm. The electronic oscillation in the polar plate and the dipole polarization in the dielectric layer contribute to the coordination of strong surface reflection and high internal absorption. The maximum strain energy of the membrane can reach 30.1%, and its high strength and flexibility are integrated together due to its unique bicapacitor and 3D network structure.

Herein, collective engineering of defects and concavities in thin‐shelled hollow amorphous carbon with discrete graphite nanocrystals is proposed to identify the effective pathways of dielectric loss for broadband response and strong microwave absorption. The appropriate conductive net and charge imbalance is the primary essential factor to enhance dielectric loss capacity; then defects in thin‐shelled amorphous carbon, induced intense dipole polarization, are more critical to achieve broadband response than concavity and geometry effect. As a result, the thin‐shelled hollow amorphous carbon with more defects demonstrates a more remarkable broadband response capability with an effective absorption bandwidth (reflection loss, RL≤ −10 dB) of 8.08 GHz and efficient dissipation of −80.70 dB.

By leveraging its gradient morphology, IMN‐1/2 achieves a pressure detection limit as low as 0.3 Pa and an ultrahigh sensitivity of 2980.23 kPa⁻¹ in low‐pressure range, enabling the effective monitoring of extremely weak breathing pressure signals.

Herein, a new strategy is developed to rationally integrate N, S‐co‐doped carbon (CNS), and CoS2 on cyano‐rich PCN (PCN‐Cy) for photosynthesis of H2O2 under ambient conditions. The engineering with cyano groups (electron‐withdrawing groups) promotes the bulk charge separation of PCN.

Besides, the N, S‐co‐doped carbon performs as an electron channel to promote migration of charges at the interface of PCN‐Cy and CoS2. Accordingly, the as‐synthesized cyano‐rich PCN photocatalyst integrated with N, S‐co‐doped carbon and CoS2 exhibits a remarkable activity of 321.9 µm h−1 for photocatalytic production of H2O2, which is 44.9 times higher than that of the pristine PCN.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"44 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2025-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144678094","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}
