Among novel nanomaterials, MXenes, 2D transition metal carbides, nitrides, and carbonitrides have garnered substantial attention due to their high optical transparency, tunable optical properties, and excellent electrochemical performance. In particular, niobium carbide (Nb2CTx) MXene holds great promise for photoelectrochemical photodetectors (PEC PDs) due to its narrow-band photodetection capability, solution-processing, and stability under light irradiation. However, current Nb2CTx-based and 2D-based PEC PDs, in general, suffer from low photocurrent density, limited optical transparency, and poor environmental stability, hindering their practical applications. In this study, we developed a polymeric binder-free transparent reduced Nb2CTx/graphene oxide (r-Nb2CTx/GO) heterostructured thin film using a facile layer-by-layer technique. Incorporating reduced GO not only assists in improving the electrical conductivity of the heterostructure but also serves as a binder for MXene flakes. We systematically investigate the physicochemical properties of the film, its photodetection, and electrochemical performance. The optimized film exhibits outstanding transparency (70% at 550 nm), narrow-band photodetection response in the ultraviolet region, an excellent photoresponsivity of 50.21 μA W-1, and high environmental stability. Altogether, this study paves the way for developing Nb2CTx-based heterostructures for highly sensitive and environmentally stable transparent PEC PDs.","PeriodicalId":93,"journal":{"name":"Nanoscale Horizons","volume":" ","pages":""},"PeriodicalIF":8.0,"publicationDate":"2025-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144705830","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 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. This study can provide guidelines for effectively harnessing sustainable green energy sources in the future.","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":"144705826","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, 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.

This platform incorporated the photothermal agent Au nanorods (AuNRs) and thermosensitive liposomes encapsulated with the photosensitizer precursor 5-aminolevulinic acid (ALA). Due to the satisfactory photothermal conversion effect of the ALA@lipo/Au/Gel/PGA composite scaffold, the use of near-infrared (NIR) light not only ablated the cancer cells in the scaffold through photothermal therapy (PTT) but also induced the accelerated release of encapsulated ALA from the thermosensitive liposomes. After uptake, ALA could generate cytotoxic reactive oxygen species to increase tumour cell elimination efficiency via photodynamic therapy (PDT). Both in vitro and in vivo experiments demonstrated the synergistic anticancer effects of the composite scaffold.

Hence, in this study, we investigated for the first time the impact of PS-MPs with different diameters on six species of common pathogenic and probiotic bacteria and further deciphered molecular mechanisms underlying the boosting support of PS-MPs for Vibrio cholerae proliferation. The results revealed that PS-MPs (100 nm to 5 μm, 0.1-100 mg L-1) promoted the reproduction of V. cholerae, but blocked the growth of Vibrio parahaemolyticus, Klebsiella pneumoniae, Klebsiella oxytoca, Staphylococcus aureus, and Lactobacillus plantarum, showing different size- and concentration-dependent action modes. The PS-MPs (100 nm to 5 μm, 100 mg L-1) significantly reduced the negative charge on the cell surface of V. cholerae and consequently increased the bacterial cell surface hydrophobicity and membrane fluidity, biofilm formation and self-aggregation capacity (p < 0.05). Comparative transcriptome analysis uncovered significantly up-regulated metabolic pathways in V. cholerae after exposure to the PS-MPs (100 nm, 100 mg L-1) for 8 h, leading to enhanced chemotaxis, flagellar motility, biofilm formation, energy metabolism and antioxidant defense. In vitro cell model experiments showed that the pre-exposure significantly increased the adhesion and invasion percentages of V. cholerae on human Caco-2 cells (p < 0.05). Overall, the results of this study not only fill the gaps in the interaction between the PS-MPs and common bacteria, but also highlight the amplified hazard of co-pollution by PS-MPs and V. cholerae, a leading waterborne pathogen worldwide.","PeriodicalId":74,"journal":{"name":"Environmental Science: Processes & Impacts","volume":" ","pages":""},"PeriodicalIF":4.3,"publicationDate":"2025-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144697138","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
