However, their power conversion efficiency and stability are significantly hindered by lattice defects and nonradiative recombination losses at the interface between the perovskite film and electron transport layer (ETL). Herein, we report the incorporation of multifunctional potassium acetate (KAc) into SnO2 ETL. Through thermal diffusion of K+ and CH3COO– during annealing, these ions electrostatically penetrate the surface and grain boundary, effectively passivating the formation of bulk defects. The resulting KAc-SnO2 ETL exhibited uniformity, low defect density, and high conductivity, providing an ideal ETL film for the subsequent deposition of perovskite films, thereby enhancing interfacial charge transfer and device efficiency. The optimized device achieved a PCE of 21.76%, a 14% increase over the control device (19.16%), and retained 88.9% of its initial PCE after 1000 h, offering a promising approach for scalable manufacturing in the perovskite industry.","PeriodicalId":53,"journal":{"name":"Nano Letters","volume":"58 1","pages":""},"PeriodicalIF":10.8,"publicationDate":"2025-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143842076","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}

Calcium ions facilitate electrical signal transmission and ionic interactions, while spiropyran enables photoswitchable color and fluorescence. Density functional theory and Fourier transform infrared analysis reveal abundant hydrogen bonding, ionic associations, and van der Waals forces, contributing to stretchability, adhesion, and self-healing, making them ideal for epidermal electrodes. The hydrogel also shows potential in optical printing and anti-counterfeiting applications due to spiropyran’s reversible photochromic and photoluminescent behaviors.

This study leverages advanced electron microscopy techniques to probe the intricate pore architecture of HC and directly visualize sodium storage within its pores. By employing an HC material (PHC-1) with rich closed pores as the platform material, electron tomography is utilized to reconstruct the pore architecture of PHC-1, providing quantitative insights into porosity, pore size, and pore structure. Low-dose electron microscopy visualizes metastable sodium clusters filling up within the pores during sodiation.

However, the role of surface nanotopography in this process remains unclear. Herein, we reveal the critical role of surface nanotopography by measuring adhesion forces utilizing fluidic force microscopy (FluidFM). The antibody-coated nanospiky surface exhibits cell adhesion force 1 to 2 orders of magnitude higher than those of the flat, nanospiky, and antibody-coated flat surfaces. This amplified effect is related to a time-dependent reversal, with adhesion force on nanospiky surfaces initially weaker than that on flat surfaces but eventually surpassing it. Mathematical simulations further demonstrate that micro-nanostructured surfaces maximize contact points, enabling multiscale, multipoint cell–substrate interactions, consistent with experimental results. From thermodynamic and kinetic perspectives, we propose a multiscale, multipoint recognition model based on the synergistic effect of topographical matching and molecular recognition.

Here, we report an efficient all-inorganic CsSnI3-based PeLED by employing a multifunctional hesperetin additive to modulate the crystallization kinetics and inhibit the oxidation process of the perovskite films. Hesperetin possesses hydroxyl groups alongside oxygen atoms offering lone electron pairs, which form hydrogen bonds with I– and strongly coordinate with Sn2+, respectively, slowing down crystallization of CsSnI3 and resulting in high coverage density films. Importantly, the coordination of hesperetin with Sn2+ protects the perovskite films from Sn2+-to-Sn4+ oxidation. Finally, we demonstrate efficient and stable PeLEDs with a peak at 948 nm, an external quantum efficiency of 4.7%, and a half-lifetime of over 11 h.","PeriodicalId":53,"journal":{"name":"Nano Letters","volume":"29 1","pages":""},"PeriodicalIF":10.8,"publicationDate":"2025-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143842080","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}

To overcome these limitations, we herein report nanocolloidal supramolecular plastics (NSPs) assembled from newly emerging nanoparticles, namely, carbonized polymer dots (CPDs) modified with ureido pyrimidinone groups. These NSPs display good mechanical properties, unique photoactivated room-temperature phosphorescence (RTP), and excellent solvent stability. Notably, NSPs are recyclable with maintenance of their original mechanics and photoactivated RTP after several usages. Furthermore, photoactivated RTP with multiple colors is achieved by incorporating organic molecules into NSPs. We show proof-of-concept applications of NSPs in high-level information security. The results in this work pave an avenue toward functional materials assembled from CPDs and will advance the development of innovative nanomaterials for sustainable applications.","PeriodicalId":53,"journal":{"name":"Nano Letters","volume":"5 1","pages":""},"PeriodicalIF":10.8,"publicationDate":"2025-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143837056","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}
