A diverse range of material combinations, including hexagonal boron nitride, transition metal dichalcogenides and graphene, with electronic properties spanning from insulating to semiconducting, metallic, and semimetallic, have been explored to tune the properties of these heterostacks. However, understanding the interactions and charge transfer between the stacked layers remains challenging, particularly when more than two layers are involved. In this study, we investigate the charge transfer in a potassium-adlayer/graphene/lead-monolayer heterostructure stacked on a SiC substrate. Using synchrotron-based angle-resolved photoemission spectroscopy, we analyze the band structure of each layer, focusing on the charge transfer from K to the underlying 2D layers. Since K forms a (2×2) overlayer with respect to graphene, the amount of charge carriers donated by K can be determined. Our findings reveal that adsorption of K not only leads to a significant n-doping of the adjacent graphene layer but also to an electron transfer into the Pb monolayer. Remarkably, ≈ 44% of the electrons donated by the K adlayer are transferred into its second nearest neighbouring layer, i.e. Pb, while ≈ 56% remain in the graphene.","PeriodicalId":92,"journal":{"name":"Nanoscale","volume":"19 1","pages":""},"PeriodicalIF":6.7,"publicationDate":"2025-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144747141","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As essential components of innate immunity, neutrophils play a dual role in sepsis. Initially, they protect tissues by phagocytosing pathogens and releasing antibacterial substances. As the disease progresses, however, they become over-activated and exacerbate tissue damage by triggering release of cytokine and neutrophil extracellular traps (NETs). Nanomaterials, leveraging their unique size-dependent properties, surface modifiability, and drug-loading capacity, offer a strategy to overcome the critical challenges of poor drug targeting and low bio-availability in sepsis therapy. Current studies mainly concentrate on nanomaterials targeting macrophages. However, only limited research work is about nanomaterials targeting neutrophils that have emerged as a superior therapeutic focus due to their crucial roles in sepsis progression. This review emphasizes the design principles for neutrophil-targeted nanomedicine delivery systems, including transmembrane biomimetic technology, surface receptor-specific recognition, exploiting the phagocytosis of activated neutrophils, and targeting neutrophil-derived microenvironmental signals. We elucidate the targeting mechanism, and discuss the current challenges and future research directions.","PeriodicalId":92,"journal":{"name":"Nanoscale","volume":"111 1","pages":""},"PeriodicalIF":6.7,"publicationDate":"2025-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144747143","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

CVD graphene coatings on biomedical devices such as contact lenses (CLs) offer several advantages, such as shielding from electromagnetic wave interference and dehydration protection. However, its protective effect against bacteria adhesion remains unexplored. In this study, we designed a series of antimicrobial peptide (AMP)-modified CVD graphene coating on polydimethylsiloxane (PDMS), a biocompatible CLs material. AMPs were successfully conjugated on CVD graphene coating, with negligible impact on the light transmittance. The resultant coating displayed contact angles of less than 50° and protein deposition of less than 9.4 µg cm-2, indicating transparency, wettability, and protein deposition suitable for biomedical devices. AMPs conjugation on the graphene surface prevented biofilm formation by Pseudomonas aeruginosa (P. aeruginosa), as evidenced by lower colony counts and bacterial metabolic activity. The antimicrobial activity and biocompatibility of the coatings were further demonstrated using ex vivo porcine skins and in vivo rabbit eyes respectively. Overall, this study highlights the potential of AMP-modified CVD graphene coating to minimize bacterial infection and prevent biofilm formation.","PeriodicalId":92,"journal":{"name":"Nanoscale","volume":"718 1","pages":""},"PeriodicalIF":6.7,"publicationDate":"2025-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144747183","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Particularly, the under-oil liquid self-transport is a significant pathway for manipulating the volatile liquids. Although numerous functional surfaces have been developed to facilitate the directional self-transport of liquids (e.g., water, oil) in the air, reports on the self-transport of liquids in oily environments remain scarce. Herein, inspired by the lotus leaves and cactus spines, we propose a bionic superwetting gradient wedge-shaped surface (SGWS) for under-oil self-transport of liquids. The SGWS was fabricated through a combination of femtosecond laser texturing and hydrophobic modification. The as-prepared SGWS can achieve fast and continuous self-transport of a single droplet under-oil, exhibiting a maximal transport velocity of over 250 mm/s and transport distance of over 150 mm. The effect of wedge-shaped angle, inclined angle, and surface tension on the self-transport behavior of liquid on the SGWS was systematically investigated and the underlying mechanism was revealed. Furthermore, the potential applications of the SGWS in complex fluid manipulation, droplet microchemical reactions, cargo transport, and oil surface particles collection were explored in detail. This work offers a novel strategy for realizing under-oil liquid manipulation without energy input, showing promising applications in the industry.","PeriodicalId":92,"journal":{"name":"Nanoscale","volume":"26 1","pages":""},"PeriodicalIF":6.7,"publicationDate":"2025-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144747184","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Owing to the presence of abundant P-O bonds in β-HCCD and the unique cavity structure of β-CDs, β-HCCD exhibits adsorption efficiency exceeding 98% for scandium ions (Sc³⁺) within acidic solution with the hydrogen ion concentrations ranging from 5 mol·L-1 to 10⁻5 mol·L-1. Meanwhile, the complete capture of Sc3+ by β-HCCD can be accomplished within 2 minutes, and the adsorption isotherms demonstrated an outstanding alignment with the Freundlich model, exhibiting a maximum adsorption capacity of 101.0 mg·g⁻¹. What’s more, β-HCCD can be directly applied to industrial acidic wastewater without prior pretreatment, achieving an efficient recovery rate of 87% for Sc3+.

Photocatalytic ammonia synthesis technology provides a revolutionary solution for green ammonia economy by realizing efficient nitrogen reduction under mild conditions with solar energy as the driving force. In this paper, we systematically review the mechanism of photocatalytic nitrogen reduction reaction, focusing on the adsorption activation of nitrogen molecules, electron transfer pathways, and intermediate product regulation strategies, and review multiple types of photocatalyst systems including metal oxides, sulfides, bismuth-based materials, and carbon-based materials. Modification strategies such as defect engineering, single-atom modification, heterojunction design and plasma effect can significantly optimize the light absorption range, suppress carrier recombination and enhance the active site density. It is further pointed out that the existing catalytic systems still face bottlenecks such as low quantum efficiency, photocorrosion, and scale-up reactor design, and the future needs to promote the photocatalytic synthesis of ammonia from the laboratory to the industrialization through the multiscale synergistic innovation. This study provides theoretical guidance and practical framework for the design and development of an efficient and stable photocatalytic ammonia synthesis system, which is scientifically important for achieving the goal of carbon neutrality.","PeriodicalId":92,"journal":{"name":"Nanoscale","volume":"1 1","pages":""},"PeriodicalIF":6.7,"publicationDate":"2025-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144747186","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we introduce a novel bottom-up approach for the synthesis of submicron MgO particles with superlative humidity resistance and thermal conductivity. Spray drying a polymeric precursor solution synthesized via the polymerization of citric acid and ethylene glycol followed by a two-step heat treatment involving oxidation and liquid-phase sintering affords MgO particles with dense morphologies and excellent humidity resistance (1.03% weight variation). These submicron-scale, humidity-stable MgO particles significantly enhance the thermal conductivity of a polydimethylsiloxane matrix, achieving 6.0 W m−1 K−1 at 80 vol% filler content, significantly higher than that of composites without submicron MgO at the same filler content (4.4 W m−1 K−1).

In this work, we present a straightforward and controllable synthesis method for nickel–cobalt bimetallic layered double hydroxide (LDH) derived from a metal-organic framework (MOF) precursor in an alkaline medium. The Ni/Co ratio was systematically tuned to induce distinct hydroxide phase transformations, where a high Ni content favored the formation of the α-phase hydroxide with superior catalytic activity, while a high Co ratio led to β-phase hydroxide formation. Advanced X-ray absorption spectroscopy (XAS) and Raman analyses revealed that the optimized Ni-rich LDH exhibited a unique mixed octahedral (Oh)/tetrahedral (Td) coordination, with a tetrahedral-dominant structure that enhanced charge transfer and electronic conductivity. Additionally, the Ni-rich LDH facilitated the formation of trivalent metal (Ni3+/Co3+) species, promoting stronger redox activity essential for lactate oxidation. The optimized Ni-rich LDH modified screen-printed carbon electrode demonstrated outstanding electrochemical performance, achieving a high sensitivity of 63.66 ± 3.86 µA mM⁻¹ within a lactate concentration range of 0~12.5 mM at an applied potential of 0.60 V (vs. Ag/AgCl/3 M KCl) in alkaline medium. Furthermore, as proposed biosensor exhibited excellent repeatability, maintaining 85.70% of its initial response after 18 days under room temperature, highlighting its remarkable stability for long-term applications.
