However, effectively harvesting this energy remains challenging, largely due to the inherently slow evaporation of water. Here, we present a high-performance hybrid generator that efficiently extracts water-phase transition energy through a multiscale structural design. The system integrates an arched multifunctional film with a polarized PVDF layer, enabling simultaneous photothermal, hydrovoltaic, and pyroelectric energy harvesting. Under optimized conditions, the device achieves a photothermal evaporation rate of ∼1.53 kg m^-2 h^-1 with a conversion efficiency of ∼96% enabled by rational microcomponent regulation, which is ∼30% higher than its planar counterpart. The hydrovoltaic output reaches a <i>V</i>_OC value of ∼1.13 V and an <i>I</i>_SC value of ∼6.46 μA, delivering a power density of ∼611 μW m^-2 that is 8.5-fold higher than previous designs under 1 sun illumination in seawater. The generator also yields a pyroelectric <i>V</i>_OC value of ∼143 V and an <i>I</i>_SC value of ∼694 nA, with a peak power density of ∼13.58 mW m^-2. Notably, these electrical outputs surpass earlier reports by >80%, attributed to enhanced interfacial temperature oscillations driven by the arched geometry. This platform reliably powers small electronic devices and enables a self-driven electrocatalytic system for seawater disinfection, achieving sodium hypochlorite production by coupling the generator with commercial Pt electrodes. Our multiscale design offers new insights for developing self-sustaining energy systems capable of harvesting and converting water-based energy for practical applications.</p>","PeriodicalId":87,"journal":{"name":"Materials Horizons","volume":" ","pages":""},"PeriodicalIF":12.2,"publicationDate":"2025-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144688373","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}

Two types of particles model the bidisperse suspension: the small particles of radius <i>R</i>_s and the large particles of radius <i>R</i>_l. The size ratio, <i>ξ</i> = <i>R</i>_l/<i>R</i>_s, defines the particle size difference. The total volume fraction of the suspension, <i>ϕ</i>, is obtained from <i>ϕ</i> = <i>ϕ</i>_s + <i>ϕ</i>_l, where <i>ϕ</i>_s and <i>ϕ</i>_l are the volume fractions of the small and large particles, respectively. The magnetic dipole-dipole interaction among the small particles and the large ones is characterized by the dipolar coupling parameters <i>λ</i>_s and <i>λ</i>_l, respectively. The interactions among the applied magnetic field and the magnetic dipoles of the small and large particles are measured by the Langevin parameters <i>α</i>_s and <i>α</i>_l, respectively. This study performs Brownian dynamics (BD) simulations of a bidisperse suspension comprising <i>N</i> = 1000 particles, with <i>ϕ</i> = 10^-3 and <i>ϕ</i>_s = <i>ϕ</i>_l = 5 × 10^-4.

Our results show a rich variability in the microstructure as <i>ξ</i> increases. As the large particles increase in size, they exhibit a greater magnetic dipole moment, which induces a non-uniform local magnetic field around them. The surrounding small particles then aggregate with the large ones, driven by this local magnetic field. Small <i>α</i>_s values lead to the formation of flux-closure structures such as rings of small and large particles as well as shell-like structures, which consist of small particles surrounding the large ones. The formation of these microstructures directly affects time-dependent magnetization of the suspension, which exhibits a decay with time in the limit of long times. These findings have important implications for synthesizing magnetic colloidal suspensions with enhanced properties.</p>","PeriodicalId":103,"journal":{"name":"Soft Matter","volume":" ","pages":""},"PeriodicalIF":2.9,"publicationDate":"2025-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144688417","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

On the basis of a series of our previous published studies that showed that black rice-based functional foods have multi-functional health benefits in rodents, including protection of mice and rats against inflammation and alcohol-induced hangovers, we were motivated to determine the protective effect of a polysaccharide-containing bioprocessed (fermented) black rice bran product (BRB-F) to prevent alcohol-induced liver damage. BRB-F prevented dietary alcohol-induced increases in both whole liver and in liver fat weights, serum levels of hepatic enzymes and bilirubin, oxidized liver glutathione, and proinflammatory serum and adipocyte cytokines. Silymarin, a plant phenolic anti-inflammatory agent, cooperated with BRB-F to increase the prevention of alcohol-induced liver damage. BRB-F and silymarin also prevented direct toxicity of HepG2 human liver cells in culture by reducing reactive oxygen species. Mechanistic aspects and suggestions for further research are discussed.

Traditional identification methods are often complex, require expensive equipment, and are time-consuming. This article proposes a rapid detection method for the botanical origin of honey based on an electronic tongue (ET) and hyperspectral imaging (HSI) combined with a CNN-transformer fusion model. First, gustatory and spectral data of honey samples from different botanical origins are collected by ET and HSI systems, respectively. A CNN-transformer fusion model is proposed to perform feature extraction, information interaction, and pattern recognition on the collected ET and HSI data. This model employs a dual-path CNN-transformer to capture local and global features of ET and HSI signals at different scales. A multi-scale interaction module is designed to enhance cross-modal communication and facilitate information sharing between the ET and HSI information. Finally, the contrastive information bottleneck (CIB) module is adopted to optimize mutual information through contrastive learning and enable the integration of ET and HSI features for classification and recognition. The experimental results demonstrate that this method achieves superior recognition accuracy in classifying and identifying honey botanical origin compared to that using either the ET or HSI alone. Its experimental mean test set accuracy, precision, recall, and F1 score reached 99.08%, 99.09%, 99.05%, and 0.9906, respectively.

In this study, we report ultra-strong, highly ion-conductive bio-membranes fabricated through phosphorylation-assisted cell wall engineering.
