To overcome this limitation, a novel nano-formulation, polyoxin B@ZTS is developed, utilizing agricultural byproducts, tea saponin, and zein. This formulation features a small particle size, high leaf deposition efficiency, and excellent dispersion properties. Leveraging a disulfide bond system, polyoxin B@ZTS is designed to respond to the intracellular reducing environment, enabling controlled release of polyoxin B. Remarkably, the nano-formulation facilitates the penetration of physiological barriers, achieving equivalent insecticidal and fungicidal efficacy to polyoxin B at only one-fifth of the dosage.

However, the use of carbon electrodes instead of hole transport materials and noble metal electrodes leads to energy level mismatch, which limits the power conversion efficiency (PCE) of p-MPSCs. In this work, a molecular doping strategy is proposed employing cyclopentylmethanamine to passivate surface and subsurface crystal defects in perovskite layers while inducing an energy shift toward the p-type in the perovskite region within carbon electrodes. This approach facilitates the formation of a perovskite homojunction at carbon micro-interfaces between carbon electrodes and perovskites. Results demonstrate that the formation of this homojunction optimizes the internal energy level alignment of devices, thereby increasing driving force for hole transfer to carbon electrodes. Ultimately, the devices optimized through this strategy increase the PCE from 17.50% to 19.50% while retaining over 92% of the initial PCE after over 150 days in air ambiance. This study provides a straightforward and effective approach for designing high-efficiency and stable p-MPSCs.","PeriodicalId":228,"journal":{"name":"Small","volume":"50 1","pages":""},"PeriodicalIF":13.3,"publicationDate":"2025-01-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143050896","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}

This work proposes a physics-constrained domain adaptation framework to predict the capacities during random discharge with non-destructive mechanism diagnosis using early or random discharging information. By imposing the impedance as physical constraints in a domain adaptative layer, the interpretability and generalization of the model can be improved as the physics-constrained layer provides physical insights into the battery mechanism characteristics, enabling onboard and non-destructive diagnosis without complex tests. The learned impedances in the physics-constrained layer are well-fitted to the real ones, suggesting accurate physical insights and, therefore, good interpretability of the trained model. Furthermore, apart from capacity prediction, the aging mechanisms of the cell can be interpreted through the learned physics from this deep learning framework without impedance measurement. Such interpretation has also been validated experimentally through post-mortem analysis. This work provides an example of grey-box modeling of complex dynamic systems where deep learning models can provide certain physical details to increase the model's interpretability.","PeriodicalId":111,"journal":{"name":"Advanced Energy Materials","volume":"37 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2025-01-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143050903","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}

Thus, precisely adjusting the synergistic adsorption among key reactive species, such as HMF and OHads, on the carefully designed catalyst surface is essential for achieving satisfactory catalytic performance for HMF oxidation to FDCA as it is closely related to the adsorption strength and configuration of the reaction substrates. This kind of regulation will ultimately facilitate the improvement of HMF oxidation performance. In this work, Pt nanoparticles modified CuO nanowires (denoted as Pt/CuO@CF) are constructed for the selective electrooxidation of HMF to FDCA under alkaline conditions. The well-designed Pt/CuO@CF demonstrates highly impressive catalytic performance across a range of HMF concentrations, ranging from the commonly used concentrations to higher levels typically not explored (10, 25, 50, 75, and 100 mm) with high FEFDCA (all above 95%) and outstanding long-term stability (15 cycles). In situ experimental characterizations confirm that the designed heterogeneous interface between Pt and CuO enhances the enrichment of HMF and OHads species on the catalyst surface.

Herein, we propose a universal method for internalizing the ionic transport properties of conventional polymer semiconductors. The incorporation of a tetrafluorophenyl azide-based photochemical cross-linker with a tetraethylene glycol bridge into poly(3-hexylthiophene) (P3HT) significantly enhances the performance and operational stability of ion-gating devices. Changes in the characteristics of the OECTs with cross-linked P3HT are minimal even after 100 cycles of operation; moreover, the cross-linked OECTs exhibit faster switching properties. In addition, the enhanced doping efficiency allows for the clear observation of plasmon resonances in nanostructured, highly doped P3HT. We believe that the proposed technique for internalizing ionic transport abilities can be applied to various ion-based semiconductor applications.","PeriodicalId":21,"journal":{"name":"ACS Nano","volume":"84 1","pages":""},"PeriodicalIF":17.1,"publicationDate":"2025-01-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143055497","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 work explores the impact of reduced graphene oxide (rGO) ornamentation on chemi-resistive LPG sensing using MAPbI3 halide-perovskite, which is manufactured via a straightforward co-precipitation technique. Because of its strong surface reactivity and semiconducting characteristics, MAPbI3 is essential to LPG sensing. When r-GO is used to decorate MAPbI3, a p-n heterojunction is created, which greatly improves charge carrier migration and separation and improves junction performance. When subjected to 500 ppm LPG, the MAPbI3@0.2 rGO heterojunction showed a remarkable response of 83% compared to the pristine MAPbI3 at 120 °C. It also had a reduced response time of 46 seconds and a recovery time of less than 500 seconds. The increased specific surface area of rGO, which results in more active sites for LPG molecule adsorption and less charge transfer resistance, is thought to be responsible for this improved performance. Amazingly, the material performed consistently over several cycles and maintained its sensitivity at 80°C. The sensor has potential for use in commercial applications because of its great sensitivity and stability at low temperatures. The efficiency of MAPbI3@rGO p-n heterojunction as dependable LPG sensors is highlighted by this work, providing notable increases in safety in a variety of settings.","PeriodicalId":344,"journal":{"name":"Journal of Alloys and Compounds","volume":"49 1","pages":""},"PeriodicalIF":6.2,"publicationDate":"2025-01-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143055560","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}

A suitable tool for studying long-range interactions in polycrystalline materials is the orientation correlation function. It was introduced as early as 1965 using the concept of mesotexture which incorporates information about grain orientations and geometries. However, its application has been limited because most materials’ characterisation works are still focused on conventional texture analysis. More recent studies proved that grain-grain interactions were independent of grain size, but did not go further to consider the longer-range interactions on structure development. The present study uses a novel discrete methodology for reconstruction and analysis of polycrystalline structures obtained by EBSD microscopy that allows for the first time to reveal and quantify the long-range effects on structure evolution of severely deformed Cu-0.1%Cr-0.1%Zr, Cu-0.1%Cr-0.1%Zr-0.05%Y, Cu-0.3%Cr-0.5%Zr and Cu-0.25%Mg (wt%) alloys. It is shown that the first- and second-order grain neighbours in all considered alloys obey scale-invariant power-law dependence as revealed in the previous studies with the first-order grain neighbours. However, our results show that the scale invariance extends much farther, between the fourth and seventh grain neighbours, depending on the material and accumulated plastic strain. These results cannot be explained by the conventional size effect reasoning discussed in previous publications. They suggest that the material discreteness, in the sense of numbers rather than sizes of grains, is the origin of the observed long-range correlations and the emergence of mesostructure that breaks the scale invariance.","PeriodicalId":238,"journal":{"name":"Acta Materialia","volume":"40 1","pages":""},"PeriodicalIF":9.4,"publicationDate":"2025-01-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143055587","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}

Although conductive polymer composites (CPCs) are used to replace traditional metals as an effective strategy for managing undesirable electromagnetic waves, CPCs have a non-negligible trade-off in the enhancement of electromagnetic interference (EMI) shielding effectiveness and absorption coefficient because of their reflection-dominated EMI shielding mechanism. Therefore, to alleviate secondary electromagnetic pollution, absorption-dominated EMI shielding composites with asymmetric structures are urgently needed. Recently, asymmetric structural designs for absorption-dominated EMI shielding composites have advanced significantly, but have seldom been summarized and discussed in detail. Consequently, this review first systematically summarizes the current progress of absorption-dominated EMI shielding composites with asymmetric structures after a brief clarification about the necessity and configuration of asymmetric structure design. Afterward, various absorption-dominated EMI shielding composites with asymmetric fiber, layered, porous, composite structures are systematically described. Besides, the versatility of absorption-dominated EMI shielding composites with asymmetric structures is briefly introduced. Finally, the current challenges and prospects are proposed to guide future advancement in the EMI shielding field.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"124 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2025-01-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143055666","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}

Ultrathin contorted polyamide films with enhanced free volume demonstrate an impressive 8-fold increase in water permeance while maintaining equivalent salt rejection compared to conventional polyamide membranes made with m-phenylenediamine and trimesoyl chloride monomers. The solution-based molecular layer-by-layer (mLbL) deposition technique employed for membrane fabrication sequentially reacts a shape-persistent contorted diamine monomer with a trimesoyl chloride monomer, forming highly cross-linked, dense polyamide networks while avoiding the kinetic and mass transfer limitations of traditional interfacial polymerization. The mLbL process allows precise nanoscale control over polyamide selective layer thickness, network structure, and surface roughness. The resulting controlled film thicknesses enable direct measurements of water and NaCl permeabilities. The permselectivities of contorted polyamide membranes surpass those of commercial desalination membranes and approach the reported polyamide upper bound. Solution-diffusion transport modeling indicates that this high permselectivity may be attributed to enhanced water transport pathways in the contorted polyamides that increase water diffusivity-permeability while maintaining high solute rejection through solubility-selectivity.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"59 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2025-01-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143055698","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}
