Herein, a facile route is reported to craft a battery of high-loading (up to 9.36 wt.%) and readily accessible single transition-metal atoms anchored on hierarchically porous hollow carbon nanospheres (denoted TM-SAC-HC; TM═Fe, Co, Ni, and Cu) as robust electrocatalysts for oxygen reduction reaction (ORR). Intriguingly, the TM-SAC-HC possesses a hollow interior with well-structured porosities on the carbon shell. Such hierarchically porous hollow carbon nanospheres adequately expose the dense metal-atom active sites, boosting the mass transport. Remarkably, Fe-SAC-HC in an alkaline electrolyte manifests a superior ORR activity (E1/2 = 0.92 V) and an excellent durability (ΔE1/2 = −15 mV after 30 000 potential cycles and 90% current retention after 48 h continuous operation), outperforming most state-of-the-art TM-based catalysts and commercial Pt/C. Zinc–air batteries assembles using Fe-SAC-HC as the air electrode deliver a peak power density of 186.6 mW cm−2 and a special capacity of 805.7 mAh g−1. Moreover, theoretical calculations reveal that Fe─N4 moieties situated within micropores significantly lower energy barriers, leading to superior ORR activity. This work provides a foundation for the rational design of high-efficiency catalysts for energy conversion and storage.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"41 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2025-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143940040","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}

Conventional strategies focus on modifying electrolyte compositions or interfacial coatings but fail to fundamentally regulate lithium deposition at the nanoscale. Here, Electrostatic catalysis-driven asymmetric solid-electrolyte interphase (SEI) formation, achieved via a pulsed positive voltage pretreatment, is introduced. This process induces site-selective decomposition of electrolyte components, generating LiF-rich SEI on flat surfaces and Li2O-rich SEI in surface pits, thereby directing lithium plating into pits and suppressing dendrite formation. Experimental and computational studies reveal that electrostatic enrichment of PF6− anions at positively charged interfaces accelerates their decomposition, while pit regions, depleted of anions, promote solvent-derived Li2O formation. Lithium metal anodes with this asymmetric SEI exhibit stable cycling for over 350 h at 1 mA cm−2, outperforming conventional SEI. Full cells paired with LiCoO2 (LCO) cathodes achieve 96.1% capacity retention after 400 cycles at 1 C, compared to 56.8% for conventional SEI. These findings introduce electrostatic catalysis as a powerful interfacial engineering strategy, enabling high-performance lithium metal batteries through precise SEI control.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"17 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2025-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143940357","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}

By precisely tuning octahedral tilt/rotation, the enhancement of SOT efficiency is achieved, and the corresponding spin Hall conductivity can be increased from the value of 2.48 to 7.56 × (ℏ/2e) × 104 Ω−1 m−1. The thickness dependence of spin Hall conductivity indicates that SOT originates from the bulk spin Hall effect.

Such integration can deepen the understanding of material mechanisms by screening physical and chemical features to uncover explicit intrinsic relationships. Thus, it promotes the advancement of materials science, representing a promising avenue for artificial intelligence (AI) applications in this field. In this review, the algorithms, functionalities, and applications in materials underlying interpretable machine learning approaches are summarized and analyzed.

Herein, self-adaptively tuning the built-in electric field is first adopted and demonstrated as a valid strategy to design high-rate LVO-based anodes, using a specifically designed heterostructure of LVO nanoparticles in situ grown on industrial waste yeast cell wall-derived carbon (C@LVO). A built-in electric field from external LVO to inner C in the C@LVO accelerates Li+ diffusion during lithiation. After full lithiation, a new heterojunction of LiyC@Li3+xVO4 forms with a flipped built-in electric field. This adaptive field reversal accelerates Li+ diffusion during both lithiation and delithiation, consistently triggering excellent reaction kinetics. The as-synthesized C@LVO anode exhibits an exceptional reversible capacity of 855.0 mAh g−1 and impressive rate performance (500 mAh g−1/5 A g−1). Furthermore, C@LVO‖LiFePO4 full cell demonstrates excellent fast-charging capability, achieving 223.5 Wh kg−1 at 9.1 kW kg−1, while maintaining 95.8% capacity retention after 2000 cycles.

However, their performance is hindered by phase instability under light exposure and electrical bias, driven by iodine expulsion, which disrupts charge transport and is further exacerbated by trap-mediated intense photoluminescence (PL) blinking. This study investigates the nature of these trap states and their role in carrier recombination through ensemble- and single-particle-level analyses. These findings highlight the critical role of passivating ligands in stabilizing PNCs, identifying ascorbic acid (AA) as an optimal surface passivation due to its multidentate binding capability, as further supported by DFT calculations. Trion blinking in untreated PNCs indicates the presence of long-lived trap states, whereas AA-treated PNCs, which retain only shallow traps near the band edges, exhibit exclusively band-edge carrier (BC) blinking. AA-treated PNCs double the ON fraction in PL trajectories and remain stable for over 90 days in ambient conditions. By effectively passivating deep traps, AA treatment suppresses charge carrier trapping, mitigates phase segregation, and enhances charge transport. Leveraging these improvements, AA-treated CsPbBrI2 PNCs are employed for the first time as electro/photoelectro-catalysts in the reduction of 4-nitrophenol, exhibiting exceptional performance.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"51 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2025-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143940365","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, there is currently a glaring lack of standard approaches for testing and reporting the performance of novel organic semiconductor and perovskite-based materials and device architectures for radiation detection. This absence of standardization has resulted in a recent exponential increase in publications that lack consistency in both the experimental procedures used for characterization and the interpretation of performance parameters reported.
