Here, an ultra-miniaturized fiber humidity (MFH) sensor based on near-parallel ion pathways is presented. The well-designed nanochannels significantly facilitate ion transport due to the stable charge distribution and the confined ions migration within near-parallel nanostructure, which improves the water-electricity conversion efficiency of moisture-sensitive fibers. Optimized nanochannels enable the MFH sensor to improve the response/recovery speed by ≈5 times compared to the disordered nanochannels. Additionally, the MFH sensor can be woven for ultra-miniaturization (0.50 mm2), which is much smaller than current sensors. Therefore, the integrated MFH sensor array demonstrated exceptionally high spatial resolution (sensor density of 1 mm-1), highlighting its potential in flexible wearables. This work provides new optimization strategies and assembly means for designing the high-performance humidity sensors of the next generation.","PeriodicalId":114,"journal":{"name":"Advanced Materials","volume":" ","pages":"e2411558"},"PeriodicalIF":27.4,"publicationDate":"2024-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142666769","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}

However, conventional polymer extrusion requires high energy consumption to reduce viscosity, and natural fiber reinforcement often requires harsh chemical treatments to improve adhesion. We address these challenges by introducing a sustainable framework to fabricate natural biocomposites using Chlorella vulgaris microalgae as the matrix. Through bioink optimization and process refinement, we produced lightweight, multifunctional materials with hierarchical architectures. Infrared spectroscopy analysis reveals that hydrogen bonding plays a critical role in the binding and reinforcement of Chlorella cells by hydroxyethyl cellulose (HEC). As water content decreases, the hydrogen bonding network evolves from water-mediated interactions to direct hydrogen bonds between HEC and Chlorella, enhancing the mechanical properties. A controlled dehydration process maintains continuous microalgae morphology, preventing cracking. The resulting biocomposites exhibit a bending stiffness of 1.6 GPa and isotropic heat transfer and thermal conductivity of 0.10 W/mK at room temperature, demonstrating effective thermal insulation. These characteristics make Chlorella biocomposites promising candidates for applications requiring both structural performance and thermal insulation, offering a sustainable alternative to conventional materials in response to growing environmental demands.","PeriodicalId":114,"journal":{"name":"Advanced Materials","volume":" ","pages":"e2413618"},"PeriodicalIF":27.4,"publicationDate":"2024-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142666867","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}

However, the biological applications of these compounds are limited. DESs are highly structurally tunable and exhibit remarkable biofunctionality and biocompatibility, conferring substantial benefits in the treatment of diseases. In this study, choline-chloride and mannose are used to fabricate ChCl/M DES, followed by introduction of lysozyme fibers and gallic acid for self-assembly into injectable eutectogels through hydrogen bonding and hydrophilic/hydrophobic interaction interactions. The eutectogels demonstrate almost 100% bactericidal activities against three strains and significant immune-regulation. This is supported by a decrease in the proportion of CD86-expressing cells from 64.02% to 18.17% and an increase in CD206-expressing cells from 2.53% to 29.96% through flow cytometry experiments. The eutectogels effectively inhibit alveolar bone loss and alleviated local inflammation in a rat model of chronic periodontitis owing to the promotion of gallic acid in the cell membrane by the ChCl/M DES. Hence, self-assembled eutectogels exhibit the potential to enhance the efficacy if treatments/therapies against inflammatory diseases by facilitating bacterial control, reactive oxygen species scavenging, and the regulation of macrophages by promoting cell permeation of small-molecule drugs.","PeriodicalId":114,"journal":{"name":"Advanced Materials","volume":" ","pages":"e2412866"},"PeriodicalIF":27.4,"publicationDate":"2024-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142666869","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 work, a three-step restraining strategy is introduced utilizing functional glycine amide hydrochloride to regulate pre-nucleation clustering, suppress excessive heterogeneous nucleation, and decelerate crystallization, enabling comprehensive control of the perovskite film formation processes. This approach results in enlarged grains, reduced defect densities, and highly oriented crystalline wide-bandgap perovskite films with significantly prolonged carrier lifetimes, achieving a maximum PCE of 19.97% for 1.77 eV-bandgap blade-coated PSCs. Furthermore, two-terminal tandem cells, composed of wide-bandgap perovskite top cells and 1.25 eV-bandgap perovskite bottom cells fabricated via blade coating, yield an impressive PCE of 27.11% (stabilized at 26.87%).

Despite great advances, to date there remains a lack of a comprehensive yet critical review on the thermal insulation materials.

Herein, it is reported a high-valence Ir single atom anchored on manganese oxide (IrSA-MnOx) bifunctional catalyst showing independent pathways for ORR and OER, i.e., associated 4e- pathway on high-valence Ir site for ORR and a novel chemical-activated concerted mechanism for OER, where a distinct spontaneous chemical activation process triggers direct O─O coupling. The IrSA-MnOx therefore delivers outstanding bifunctional activities with remarkably low potential difference (0.635 V) between OER potential at 10 mA cm-2 and ORR half-wave potential in alkaline solution.

The difference in side chains induces their distinctive molecular packing mode and unique crystal structure, in which ATIC-C11 displays a 3D structure with an elliptical framework, and ATIC-BO gives a rectangular framework. Their high crystallinity contributes to organized molecular packing in ternary devices, thus low energetic disorder and suppressed energy loss. Through the analysis of morphology and carrier kinetics, it is found that ATIC-BO's strong self-aggregation and immiscibility induce large aggregates and severely impede charge transfer (CT) and dissociation. Conversely, ATIC-C11's suitable crystallinity and compatibility positively regulate the crystalline kinetics during film formation, thus forming much-ordered molecular packing and favorable phase separation size in blend films. As a result, ATIC-C11-based ternary devices achieve a high efficiency of 19.28% with potential in scalability and stability, which is the top-ranking efficiency among nonhalogenated solvent-processed OSCs.

Regulated by microenvironments in specific applications, macrophages have a heterogenous nature and exist in different phenotypes with diverse functions, e.g., pro-inflammatory and anti-inflammatory. However, it is not clear whether macrophage phenotype affects nucleic acid delivery, and which one is harder to transfect, and the design of nucleic acid carriers in harder-to-transfect macrophage phenotypes is largely unexplored. Herein, it is first revealed that nucleic acid delivery efficacy in macrophages is influenced by phenotype: IL-4-treated \"M2-like\" macrophages with suppressed mammalian target of rapamycin complex 1 (mTORC1) levels are harder-to-transfect than \"M1-like\" macrophages for mRNA and DNA. This knowledge is then translated to the purpose-design of gene delivery carriers for harder-to-transfect M2 phenotype macrophages dominant upon bacteria immune evasion. By loading chloroquine in tetrasulfide bond-containing organosilica nanoparticles, the resultant composite promotes macrophage M2 polarization to M1 and increases mTORC1 levels for enhanced translation. The design is demonstrated in vitro and in vivo for pathogenic Escherichia coli (E. coli) and methicillin-resistant Staphylococcus aureus (MRSA) infections. It is expected that the findings may provide new knowledge and gene delivery solutions in other applications where the M2 phenotype macrophage is dominant.","PeriodicalId":114,"journal":{"name":"Advanced Materials","volume":" ","pages":"e2401504"},"PeriodicalIF":27.4,"publicationDate":"2024-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142666868","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}

This study, for the first time, systematically explores the photoluminescent behavior of CDs in their aggregated state, which is less understood compared to their discrete state. By investigating the effects of concentration and solvent environment, it's demonstrated that CDs could exhibit dual emission properties, shifting from blue particle emissions to red cluster emissions as they aggregate. The key to this tunable luminescence lies in hydrogen bonding, which drives the self-assembly of CDs and modulates their photo physical properties. These findings reveal that through precise control of aggregation, CDs can be engineered for advanced optoelectronic applications, including tunable light-emitting diodes (LEDs), secure information encryption, and fingerprint authentication.
