The prospect of harvesting energy from water evaporation and streaming has garnered increasing attention. Nevertheless, there still exist challenges, including insufficient liquid-solid interface contact and inadequate liquid transport. Herein, a synergistic composite material system comprising micron-scale activated carbon and nano-scale silicon dioxide particles via multistep ball milling processes is introduced. The superhydrophilic material combined with a hierarchical structure enhances capillary infiltration performance, thus ensuring continuous liquid flow and sustained transpiration. As a result, the hydrovoltaic generator achieves efficient energy harvesting (an open-circuit voltage of >4.3 V) and environmental monitoring (response to variations in sunlight intensity and wind speed). Notably, the device can maintain high voltage output for over one year, demonstrating its long-term stability.

However, achieving efficient photogenerated carrier transfer within heterojunctions remains a critical challenge in devices utilizing organic and photosensitive materials. This study demonstrates that tuning the bipolarity of perovskite quantum dots (PeQDs) through Sn doping effectively modulates electron and hole trapping properties in conjugated polymer (CP)-PeQD nanocomposites, paving the way for energy-efficient neuromorphic electronics. Optimal Sn doping enhanced PeQDs' photoluminescence quantum yield and adjusted energy levels, promoting efficient electron trapping in p-type devices while reducing hole trapping in n-type systems. Integrating Sn-PeQDs with p-type CPs (diketopyrrolopyrrole-selenophene) enabled exceptional photosynaptic behaviors, such as short-term and long-term plasticity and spike-dependent plasticity. Remarkably, p-type CPs/Sn-PeQDs with optimal Sn doping achieved ultralow energy consumption of 0.169 aJ at a drain voltage of -0.1 mV with a 1 ms light pulse, significantly outperforming earlier p-type optoelectronic synapse designs. This work underscores the potential of Sn-PeQDs as a robust strategy for designing efficient, low-energy neuromorphic systems for next-generation electronics.","PeriodicalId":87,"journal":{"name":"Materials Horizons","volume":" ","pages":""},"PeriodicalIF":12.2,"publicationDate":"2025-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144705829","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}

The influence of peptide and organic matrix properties on mineralization capacity and saturation of in situ mineralization (SIM) was investigated. Results demonstrated that peptides with characteristic nucleation domains can boost mineralization by providing more nucleation sites and strengthening organic-inorganic interactions. Meanwhile, matrix compactness negatively correlated with mineralization capacity and SIM. Combined modulation of peptide nucleation ability and matrix compactness can enhance the SIM of the matrix, increasing the amount of minerals while improving mechanical properties. The biomimetic composites/scaffolds with mineralization enhancement by peptide-organic matrix regulation were evidenced to promote cell proliferation and osteogenic differentiation, and in vivo bone regeneration by upregulating BMP2 gene expression.

The birth defects and fragile lattice result in the sluggish Li+ diffusion kinetics and unfavorable structural degradation. Moreover, lattice strain, mechanical failures, surface reconstruction, and interfacial side reactions accelerate the decay process. Here, a proof-of-principle study of the lattice plainification (LP) strategy in a high-nickel NCM cathode is reported. The introduction of Al and Zr in transition metal layers by a wet chemistry and calcination method enables the simplification of the complex lattice structures to obtain an order phase and repair the various defects of NCM, thereby enhancing the lithium-ion transport. The modified LP-NCM exhibits a high initial discharge capacity of 157.3 mAh g-1 with a capacity retention of 81% after 300 cycles at a 5C rate, significantly outperforming the pristine counterpart (50.9%). The LP-NCM/Gr pouch cells presented impressive cycling performance, achieving 80% capacity retention over 1000 cycles at 1C, which far surpasses the performance of the pristine NCM. Our method eliminates the rocksalt and disordered phases, and suppresses oxygen, lithium, and transition metal vacancies, as well as Li/Ni mixing. LP-NCM after cycling exhibits nanopores rather than cracks of pristine NCM. Our investigations reveal that the lattice plainification design approach flattens and toughens up the crystal lattice, which contributes to robust structural stability and improves the structure degradation, mechanical failures, and gas release. Our findings underscore the importance of lattice engineering and demonstrate the potential of the lattice plainification strategy for designing high-performance cathodes.","PeriodicalId":87,"journal":{"name":"Materials Horizons","volume":" ","pages":""},"PeriodicalIF":12.2,"publicationDate":"2025-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144697050","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}

In this study, we designed a heat-resistant and edible superhydrophobic coating by leveraging the unique and robust hierarchical structure of lycopodium spore powder (LSP) and utilizing natural low surface energy carnauba wax as the binder. The focus was to evaluate the hydrophobicity, heat resistance, and mechanical properties of the coating and to further demonstrate its application on liquid food packaging surfaces. The results confirmed that the lycopodium spore powder-carnauba wax superhydrophobic coating (LCW) exhibited excellent superhydrophobic properties (WCA > 150°, SA < 4°) and excellent self-cleaning function. It also has excellent anti-adhesion properties toward liquid foods with high viscosity and complex composition, such as honey, yogurt, etc. (it only takes 5170 ms and 2930 ms to completely slip on a surface with about 10° tilt, respectively). The incorporation of lycopodium spore powder notably enhanced the thermal stability of the coating, allowing it to retain a contact angle of 150° even after being subjected to high-temperature treatment at 120 °C for 2 hours. We posit that this Lycopodium-coated water-repellent material offers a promising avenue for the efficient production of biodegradable superhydrophobic coatings and holds significant potential for applications in functional food packaging.","PeriodicalId":87,"journal":{"name":"Materials Horizons","volume":" ","pages":""},"PeriodicalIF":12.2,"publicationDate":"2025-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144697049","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}

However, conventional disinfection methods often produce toxic disinfection byproducts (DBPs) such as trihalomethanes (THMs) and haloacetic acids (HAAs), which pose significant carcinogenic and environmental risks. Cold atmospheric plasma (CAP) has emerged as a promising alternative disinfection approach that generates reactive species in situ, without the need for added chemical reagents. It utilizes reactive oxygen and nitrogen species (RONS), ultraviolet (UV) radiation, and transient electric fields to effectively inactivate a wide range of waterborne pathogens. CAP disrupts microbial membranes, damages nucleic acids, and induces oxidative stress, rapidly inactivating bacteria, viruses, and fungi. A notable advancement in plasma-based water disinfection is microbubble-enhanced cold atmospheric plasma (MB-CAP), which significantly improves plasma-liquid interactions. Microbubbles (MBs) act as efficient carriers for RONS, greatly increasing the gas-liquid interfacial area and enhancing the mass transfer of RONS. This results in faster removal of pathogens compared to conventional CAP systems. Furthermore, MB-CAP offers localized and targeted treatment capabilities, making it particularly suitable for decentralized water systems, hospital wastewater, and high-load industrial effluents. This review thoroughly examines the mechanisms of microorganism inactivation by MB-CAP, reactor configurations, MB generation techniques, and disinfection performance. This review also discusses key challenges such as energy efficiency, scalability, and regulatory compliance. Future research should focus on developing hybrid CAP systems, integrating renewable energy sources, and implementing real-time monitoring tools to optimize treatment efficacy. Overall, the review highlights the transformative potential of MB-CAP as a next-generation sustainable water disinfection technology.","PeriodicalId":87,"journal":{"name":"Materials Horizons","volume":" ","pages":""},"PeriodicalIF":12.2,"publicationDate":"2025-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144697051","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}

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 VOC value of ∼1.13 V and an ISC 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 VOC value of ∼143 V and an ISC 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.
