Herein, a manageable vapor-assisted passivation strategy using functionalized amines with low saturated vapor pressure is devised to efficiently modulate the multiple imperfections on the perovskite surface, including passivation of various defects and transformation of photosensitive PbI₂ into robust and favorable one-dimensional (1D) perovskitoids. The reformation of perovskite film optimizes the interfacial structure and electronic quality, thus remarkably diminishing the nonradiative recombination loss. Consequently, the amine vapor-treated perovskite solar cell obtains an exceptional power conversion efficiency of 25.35% along with negligible hysteresis as well as superior thermal and moisture stability. Importantly, this low-cost vapor-assisted passivation strategy is universally adaptable to various perovskite systems and delivers a wide time–temperature operating window with high compatibility in high-throughput passivation of large-area perovskite films. Besides, the appropriate vapor treatment is surprisingly efficacious to repair degraded perovskites, further elucidating the reliability of the proposed strategy in regulating multiscale imperfections and its multiple specific dominances in controllable passivation.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"39 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2025-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144219061","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 solution-processable PPDFMA-<i>b</i>-(P4HS-APy) can rapidly self-assemble into an ordered nanostructure with sub-6 nm domain size after annealing at a low temperature of 80 °C for only 10 min, which defines pyrene moieties into hydrophilic P4HS blocks surrounded by a hydrophobic and insulating PPDFMA matrix to form an effective electret. By optimizing the composition and tuning the nanostructure of the electret, a high-performance transistor device with a large memory window of 74 V, a high on/off current ratio of ∼10⁵, and outstanding memory stability over 10⁴ s was obtained. Additionally, a 6 × 6 synaptic transistor array was prepared, which exhibits good uniformity and can replicate versatile biological synaptic behaviors.

This phenomenon escalates due to the aging of the population and rising comorbidities. Traditional wound care methods often prove inadequate in dealing with the complexities of chronic wounds; therefore, biomaterials have emerged as promising solutions. In response to this need, this work focuses on the development of a bilayered hybrid patch for the treatment of chronic wounds, designed with a chemical composition and morphology to exert antimicrobial activity to combat local infection and to provide specific support for cell adhesion and tissue regeneration. In particular, using gelatin and chitosan as the main constituent materials, bioactive membranes were developed and functionalized with bioresorbable hydroxyapatite nanoparticles doped with magnesium ions grown on gelatin molecules to boost regenerative stimuli. Then, they were assembled into a bilayered structure with highly tuned chemical and structural features through different fabrication techniques and biodegradation by cross-linking processes. Lastly, to confer antibacterial properties, the lower layer was medicated in situ with Vancomycin hydrochloride (VNC), selected as a case study antibiotic. The developed patches exhibit excellent physiochemical properties, including exudate absorption and moisture permeability, with both features falling within the recommended range for materials for wound healing applications. In addition, both patches exhibit adequate biodegradation times to support effective cell adhesion and proliferation, as well as drug release kinetics, with almost complete release of VNC after 48 h, necessary to achieve thorough wound disinfection. In vitro biological studies have proved their biocompatibility and on-site, long-lasting antimicrobial potential, while in vivo tests, with medicinal leeches’ model, have demonstrated their affinity for live tissue and efficacy in supporting endothelial cell proliferation by stimulating the epidermal tissue healing process.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"134 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2025-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144218918","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}

Nevertheless, the lifetime of Gr||LFP batteries remains inadequate for fulfilling long-term energy storage demands. In this study, through molecular structure design, an imidazole-based molecule, <i>N</i>,<i>N</i>′-carbonyldiimidazole (CDI), is applied as an innovative solid electrolyte interphase (SEI)-forming additive for Gr||LFP batteries. This molecular design aims to construct a dense and chemically stable SEI on a graphite anode. CDI is characterized by a low energy level of the lowest unoccupied molecular orbital and strong adsorption energy on the graphite surface, attributed to its dual-ring structure. It can be preferentially reduced at 1.58 V vs Li/Li⁺ to form an SEI enriched with nitrogen-containing species. Additionally, CDI facilitates the decomposition of PF₆^– anions, resulting in increased LiF production, which enhances the interfacial stability. As a result, the capacity retention of Gr||LFP pouch cells improves by 18% after 1000 cycles at 45 °C at a 1 P rate compared to cells with the base electrolyte. This study highlights the significance of designing electrolyte additive molecular structures to manipulate the composition and robustness of the SEI layer, offering an approach for formulating electrolytes to achieve long-lifespan LIBs.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"49 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2025-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144229207","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 study developed a hierarchical drug delivery scaffold with an outer layer of poly(lactic-<i>co</i>-glycolic acid) loaded with aspirin and an inner core of poly(L-lactic acid) containing osteogenic growth peptide (OGP), fabricated via electrospinning. In the early implantation phase, the scaffold suppresses M1 and promotes macrophage M2 polarization, shifting the periodontal microenvironment from inflammatory to regenerative.

The sequentially releasing aspirin and OGP-Scaffold (As+OGP-Scaffold) demonstrate excellent biocompatibility and potent immuno-osteogenic effects both <i>in vitro</i> and <i>in vivo</i>. Bioinformatics and Western blot analyses show that the As+OGP-Scaffold modulates macrophage polarization by inhibiting the ERK-CREB axis and activating the STAT3 pathway while promoting osteogenesis through SMAD signaling pathways and suppressing osteoclast-associated MAPK signaling.

However, the overall efficiency of alkaline water electrolysis is significantly constrained by the anode oxygen evolution reaction, where the four-electron transfer process leads to slow reaction kinetics, limiting the achievement of efficient and cost-effective hydrogen production at high-current-density. Although substantial efforts have been made in the academic community to enhance the activity of electrocatalysts, challenges remain in achieving high activity and stability of catalysts at high-current-density. To address this challenge, self-supported transition metal catalysts have attracted increasing attention due to their high conductivity and structural stability. This paper first introduces the basic principles of water electrolysis from a thermodynamic perspective, then summarizes the main challenges faced by water electrolysis catalysts at high-current-density, and discusses the advantages of self-supported electrodes in this process. Subsequently, the paper outlines strategies for selecting efficient and stable electrocatalyst substrates and optimizing their performance.
