However, the bacterial metabolic byproducts can corrode the components and micro-structures of absorbers as employed in a bacteria-rich environment, thereby progressively reducing their absorption properties. To address this problem, herein the biomass-derived porous carbon decorated with magnetic Fe₃O₄ and dielectric CeO₂ deriving from Ce-UIO-66 was obtained via co-solvothermal and calcination route. The thin-walled porous biological carbon can not only dissipate incident microwave by scattering effect, but also act as carrier to provide sufficient dielectric properties. The co-modification of CeO₂ and Fe₃O₄ with varied doping of Fe³⁺ promotes the magnetodielectric equilibrium for better impedance matching, which can couple multi-ply mechanisms of dielectric polarization, conduction dissipation, eddy-current and natural resonance loss to achieve outstanding microwave absorption. The maximum RL value reaches -60.60 dB at 15.69 GHz for 2.00 mm thickness and the widest EAB is 6.41 GHz for only 2.19 mm thickness, the simulation proves the reduction of radar cross section within wide range of incident angles as well. Moreover, the ROS generated from abundant oxygen vacancies in absorber can realize high anti-bacterial efficiencies of 82.70% and 91.60% against <i>S. aureus</i> and <i>E. coli</i>, respectively. Hence, the work proposes a novel insight to design antibacterial electromagnetic absorbers for application in complex bacterial environment.</p></div>","PeriodicalId":7220,"journal":{"name":"Advanced Composites and Hybrid Materials","volume":"8 5","pages":""},"PeriodicalIF":21.8,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s42114-025-01444-5.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145210735","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Among them, thermally conductive polymer composites have shown immense potential. However, achieving high thermal conductivity typically requires a substantial loading of inorganic fillers to form effective thermal conduction networks. To address this, this study explores the use of electric field-assisted alignment facilitated by ionic liquids (IL) to orient boron nitride (BN) and construct efficient thermal conduction pathways at low filler loading. IL/BN/PDMS thermally conductive composite films were prepared, and the mechanism of IL-assisted BN alignment under an electric field was elucidated through a combination of simulations and experiments. Molecular simulations conducted via Materials Studio (MS) reveal that the adsorption of ionic liquid (IL) on the boron nitride (BN) surface is predominantly governed by van der Waals and electrostatic interactions. This interfacial interaction enables IL to act as an orienting agent under an electric field, thereby promoting the directional alignment of BN within the PDMS matrix. The prepared composite films exhibited a thermal conductivity of 0.625 W·m⁻1·K⁻1, a significant improvement over non-aligned films (0.461 W·m⁻1·K⁻1). Additionally, the dielectric constant of the aligned films increased significantly at low frequencies, while dielectric loss rose modestly from ~ 0.5 to ~ 1.5. This study is the first to reveal how IL assists BN alignment. It highlights the advantages of electric field-assisted alignment for preparing thermally conductive composites. The findings offer theoretical insights and practical guidance for developing thermal materials and improving thermal management in advanced electronics.</p></div>","PeriodicalId":7220,"journal":{"name":"Advanced Composites and Hybrid Materials","volume":"8 5","pages":""},"PeriodicalIF":21.8,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s42114-025-01310-4.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145210831","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Accurate imaging diagnosis and timely treatment are essential for improving patient survival. Magnetic resonance imaging (MRI) is widely recognized as a promising diagnostic tool for OSCC; however, the effectiveness of conventional contrast agents is often limited by their inefficient tumor accumulation. To address this issue, a novel smart-responsive decomposable cobalt manganese oxide nanocluster (SDCM NC) has been developed to enhance tumor-specific MRI and synergistic photothermal-chemodynamic therapy (PT-CDT). The SDCM nanoclusters encapsulate small-sized cobalt manganese oxide nanoparticles (CMO NPs) within a B-type gelatin shell that is enzymatically degraded by the overexpressed matrix metalloproteinase-9 (MMP9) in OSCC. This multistage decomposition mechanism facilitates improved tumor accumulation and deeper tumor penetration. The enhanced accumulation allows for improved T1-T2 dual-enhanced MRI performance, which is further optimized using Dual-Enhanced Subtraction Imaging (DESI) to improve contrast between tumor and normal tissues. Additionally, SDCM NCs demonstrate strong •OH generation through Fenton-like reactions and exhibit high photothermal conversion efficiency, enabling synergistic PT-CDT effects. In vivo studies using an OSCC mouse model validated the efficacy of SDCM NCs, showing prolonged tumor retention, improved MRI diagnostic accuracy, and effective suppression of tumor growth through synergistic therapy. These findings underscore the potential of SDCM NCs as an innovative platform for precise diagnosis and effective treatment of OSCC.</p></div>","PeriodicalId":7220,"journal":{"name":"Advanced Composites and Hybrid Materials","volume":"8 5","pages":""},"PeriodicalIF":21.8,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s42114-025-01425-8.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145210510","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although various retinal models have been developed to study retinal vascular diseases, replicating tissue-specific microenvironments remains challenging. In particular, incorporating key features, such as the blood–retinal barrier (BRB) and narrow vascular structures, has proven difficult in previous models. To address this issue, we developed a retina-on-a-chip using an integrated 3D bioprinting system that combines multi-nozzle and triple-coaxial printing with a hybrid retinal-derived decellularized extracellular matrix (RdECM) bioink and vascular tissue-derived dECM (VdECM).

To simulate RVO, we fabricated an RVO-on-a-chip by perfusing low-density lipoprotein (LDL) and adjusting the vascular printing speed to create a narrowed vasculature. The RVO-on-a-chip successfully recapitulated RVO progression, with pathological changes originating from the blood vessels and propagating through the inner and outer BRB compartments, closely mimicking real RVO lesions. Furthermore, drug treatments applied to the chip demonstrated efficacy comparable to clinical outcomes.
