Here, it is developed an implantable deformation array sensor capable of real-time, continuous monitoring and mapping of brain deformations. The sensor features microcoil arrays embedded in ultrathin films and operates based on the principle of mutual inductance, achieving exceptional temporal resolution (<100 µs) and distance resolution (<5 µm). It is implanted the sensor between the skull and the cortex and successfully tracked continuous brain deformations across four cortical sites in rat models. These experiments are conducted under scenarios of isoflurane inhalation, mechanical impacts, and intracranial hemorrhage, where such detailed monitoring and mapping has not been achieved previously. The results reveal that brain deformations dynamically vary over time in response to both physiological fluctuations and pathological events, with deformation amplitudes decreasing as the distance from the primary site increases. This innovative approach provides a novel platform for exploring brain dynamics and their associations with neurological disorders and disease progression.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"6 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144192910","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 construction of customized COFs featuring in-plane and intramolecular asymmetric polarization is reported to boost charge separation and redox reactivity. By integrating electron donor and electron acceptor units in the COF skeleton with precise spatial arrangement, an in-plane and intramolecular polarized electronic environment is achieved that facilitates directional charge transport. The optimized COF with asymmetric electronic distribution exhibits outstanding activity for H2O2 photosynthesis under visible light, achieving a high yield of 4524 µmol g−1 h−1 in pure water and air without sacrificial agents, demonstrating high productivity and excellent stability. The photocatalytic efficiency further increases to 7316 µmol g−1 h−1 at pH 3, demonstrating excellent pH-responsive behavior. Beyond H2O2 synthesis, the optimized COF simultaneously catalyzes value-added alcohol oxidation reactions, showcasing its multifunctional catalytic capabilities. This work establishes asymmetric polarization engineering as a powerful design principle for COF photocatalysts, providing both fundamental insights into charge separation mechanisms and practical guidelines for developing sustainable photocatalytic systems.

In this review work, the relevant research progress of different metal sulfide photocatalysts in photocatalytic hydrogen evolution (PHE) of multilevel biomass resources and waste plastics is reviewed. First, the structure and modification strategy of metal sulfides are discussed, and the PHE mechanism and multi-scale synergistic effect are analyzed. Second, the effective strategies of different metal sulfides in the PHE process of multilevel biomass and waste plastics are summarized. In addition, the vital industrialization potential of the technology is also evaluated from the aspects of environmental impact and economic feasibility.

Here, trimethoxyboroxine (TMOBX) is used as a lithium-ion coordination regulator in the commercial carbonate electrolyte to improve the cycling stability of LMBs at high voltage. Owing to the strong polarized B─O bonds, TMOBX not only prefers to interact with Li+ because of the high electron density of O, but also attracts more PF6− in the solvation structure due to the positively charged B, resulting in robust and ionic conductive electrode/ electrolyte interphases rich in P─F compounds, B─O and B─F species. Moreover, TMOBX effectively eliminates HF in the electrolyte, all of which can avoid lithium dendrites, and suppress corrosion of LiNi0.9Co0.05Mn0.05O2 (NCM90) and dissolution of transition metal ions.

Hybrid hydrogel desiccants, composed of hygroscopic salts in hydrogel networks, are promising sorbents for atmospheric water harvesting (AWH) due to their excellent sorption capacity in a wide relative humidity (RH) range (10–95%) and high water retention. However, their slow sorption kinetics remain a major challenge, often requiring several hours to saturate. To address this, a highly scalable nano-/micro-confinement strategy is developed where polyacrylamide (PAM)-LiCl hybrid desiccants are confined within hollow nanoparticles (NPs), followed by assembly into raspberry-like microbeads with a NP-rich shell/hydrogel-rich core morphology via Pickering emulsion. The NP-rich shell increases surface area, while the hierarchical confinement of PAM-LiCl at the nanoscale (within NPs) and microscale (within the microbeads) effectively shortens the diffusion length. Hence, raspberry-like microbeads achieve 1.11 g g−1 water uptake at 21 °C and 65% RH within 60 min, reaching 80% saturation in 71 min—4.4 times faster than those without NPs. At 60 °C and 5% RH for 30 min, 13.6 L kg⁻¹ day⁻¹ of water is released over 16 absorption/desorption cycles. A solar-driven, sunflower seed-packing inspired AWH device is fabricated to maximize microbead loading while minimizing self-shadowing, achieving 2.39 L m⁻2 day⁻¹ water production.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"54 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144192962","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 report we demonstrate that tailoring the flexible coordination sphere of Zinc(II) complexes via subtle ligand modification promotes not only one but also three-dimensional self-assembly both thermodynamically and kinetically into higher-order fibrous morphologies, the latter being elucidated by electron tomography. As a result, coordination chemistry can be translated into both nanoscopic (fibre stiffness) and macroscopic (thermal gel stability) material properties. Utilizing dynamicity enables gelation via subcomponent self-assembly, constructing the supramolecular polymer network simultaneously with the monomer. Furthermore, coordinative dis- and reassembly via metal-ligand exchange reactions involving the first and second coordination spheres allows for control over gelation and emission of the system. Our report links concepts in supramolecular self-assembly and coordination chemistry by leveraging the unique bonding interactions that cannot be achieved for traditional monomers, promising applications in stimuli-responsive optoelectronics.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"11 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144192758","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}

Initially, rat NSPCs are cultured on 102 distinct hydrogels fabricated with varying parameters, and their attachment conditions and cell viability are evaluated. To mitigate overfitting issue, 10–20 times more virtual data points are generated from characterized NSPC attachment and viability data. A support vector machine classifier is trained on attachment data to define a feasible parameter space where NSPCs consistently adhere to biointerfaces. Subsequently, a prediction model is constructed to predict rat NSPC viability. Model interpretation reveals that biointerface stiffness is the primary factor for rat NSPC attachment and viability, with peptide loading also contributing. Leveraging these insights, the stiffness of a nerve-on-a-chip platform is optimized by adjusting the bilayer number of a polyelectrolyte multilayer, successfully enhancing neurite outgrowth.

Concurrently, the steric hindrance of the platinum shell is relieved with oxygen-independent chemodynamic activity restored. More significantly, the mild photothermal effect under near-infrared (NIR) irradiation can accelerate the disassembly to fast activate fluorescence and ROS output. Excellent performances in miRNA-21 target imaging and chemodynamic-photodynamic synergistic anticancer therapy are achieved in vitro and in vivo with negligible cytotoxicity.
