However, solute separations in this regime have stubbornly exhibited broad rejection curves where solutes with dimensions substantially smaller than the nominal pore size are rejected. The widened profile of these curves results from three distinct mechanisms. Pore-size heterogeneity convolves the single-pore response with a broad size distribution, and because Hagen-Poiseuille flow scales as the fourth power of radius, the largest pores dominate the permeate and disproportionately leak oversized solutes. Confined (hindered) transport leads to intrapore hydrodynamics, slowing a solute relative to the background solvent velocity and effectively rejecting solutes that would intuitively pass through based on size exclusion alone. Finally, the pore array presents only a limited open area to an approaching solute; under single-pass operation, a solute that does not encounter a pore mouth is recorded as rejected regardless of its size. Despite these challenges in achieving sharp separations, no fundamental phenomena preclude much narrower rejection curves in principle. Advancing toward an ideal \"step function\" rejection profile requires a systematic dissection of each broadening mechanism and a scaffolded approach where geometric, intrapore, and process architecture might collectively enable unprecedented precision in practical size-selective separations.</p>","PeriodicalId":93,"journal":{"name":"Nanoscale Horizons","volume":" ","pages":""},"PeriodicalIF":6.4,"publicationDate":"2026-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149101136","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}

Upon dye binding and selective excitation of the MDs, efficient singlet energy transfer (ET) occurs, as evidenced by the quenching of MD photoluminescence (PL), enhanced dye emission, and the emergence of an ET-induced rise component in the dye lifetime profile. Single-particle measurements under donor-selective excitation show strong ET-induced donor-acceptor PL anticorrelation, marked by a pronounced zero-delay dip [<i>g</i>²(0)] in the antibunching cross-correlation. Additional evidence for ET comes from single-particle PL trajectory analysis showing strong temporal correlation between donor and acceptor signals, and from simultaneous donor/acceptor-channel imaging under donor-only excitation, where spatially colocalized MD images confirm ET-mediated excitation of dye molecules distributed all over the MDs. Solution-phase ensemble measurements demonstrate relatively high ET efficiency (>50%) even at low bulk dye concentrations (∼1 µM). Spatially-resolved analysis further reveals ∼55% higher ET efficiency at the MD core compared to the edges, indicating preferential dye accumulation within the cavities located mostly in the core region. These results demonstrate that Cs₄PbBr₆ MDs serve as efficient ET platforms with tunable ET efficiency, providing promising potential for applications in photocatalysis, sensing, and light-harvesting technologies.</p>","PeriodicalId":93,"journal":{"name":"Nanoscale Horizons","volume":" ","pages":""},"PeriodicalIF":6.4,"publicationDate":"2026-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149078942","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}

However, it is still difficult to achieve efficient heat localization and continuous water transport in a single evaporator. In this work, a PAN-PS-PAN sandwich-structured photothermal evaporator was fabricated by sequential electrospinning using a dual-channel needle assembly. The evaporator consisted of polyacrylonitrile-polystyrene-polyacrylonitrile (PAN-PS-PAN, PPPS) layers. Carbon nanoparticles (C NPs) were incorporated into both PAN and PS precursor solutions, with a higher nominal C NP fraction in the PAN-based precursor. The PAN-rich outer layers remained strongly hydrophilic and supported water redistribution toward the evaporation interface, whereas the PS-rich middle layer remained hydrophobic and served as the principal internal thermal barrier. Therefore, the PAN-PS-PAN structure enabled continuous water supply while retaining most heat near the evaporation interface. Owing to this structural design, the PPPS evaporator showed improved water supply and heat utilization. Under one-sun irradiation, the evaporation rate reached 1.33 kg m^-2 h^-1, and the solar-to-vapor conversion efficiency was 90.5%. The evaporator also showed good purification ability for organic dye solutions, acidic and alkaline water, Tween 80/kerosene emulsion, and PEG aqueous solutions with different concentrations.

Sinomenine is a natural alkaloid with anti-inflammatory, analgesic, immunosuppressive and bone-protective effects, showing great potential in the treatment of rheumatoid arthritis. However, sinomenine suffers from drawbacks such as poor water solubility, low bioavailability and rapid degradation, which compromise its therapeutic efficacy. Tetrahedral framework nucleic acid (TFNA) is a DNA nanostructure with excellent delivery capacity for small-molecule drugs. It can bind small molecules from traditional Chinese medicine through electrostatic interactions and groove binding, thereby improving bioavailability. In this study, using TFNA as a carrier, we constructed a drug delivery system with favorable stability and biocompatibility - the TFNA-SIN complex - to deliver SIN into synovial fibroblasts, exerting anti-inflammatory effects and inhibiting cell proliferation. TFNA-SIN inhibits the expression of M1 macrophages, promotes the expression of M2 macrophages, and suppresses inflammatory cell infiltration by blocking the NF-κB and extracellular regulated protein kinase (ERK) signaling pathways.

While extensive efforts have been devoted to the AHE in 2D magnets, most studies have been confined to ultra-low temperatures or regimes far below room temperature, limiting both fundamental understanding and practical applicability. The recent discovery of several high-temperature van der Waals (vdW) ferromagnets has opened up a promising platform for investigating the underlying mechanisms and device opportunities of the AHE at and above room temperature. In this review, we provide a comprehensive overview of recent advancements of the AHE in room-temperature 2D vdW ferromagnets. We first summarize the macroscopic manifestations of the AHE in representative vdW ferromagnets operating at room temperature. Then, we provide an overview of typical vdW ferromagnetic systems exhibiting room-temperature AHE, with a particular focus on thickness dependence, Curie temperature, magnetic anisotropy, and materials engineering strategies such as chemical doping, strain engineering, and interface design, together with state-of-the-art synthesis techniques. Subsequently, we discuss and compare the key microscopic mechanisms underlying the AHE in these materials, including intrinsic Berry-curvature-driven contributions and extrinsic contributions. Based on this understanding, recent progress in electrically tuning the AHE <i>via</i> external electric fields and applied currents is systematically reviewed, highlighting their impacts on anomalous Hall resistance, coercivity, and critical temperature. We further summarize advances in different types of electrically controlled vdW magnetic prototype devices, including current-tunable AHE devices and magnetic tunnel junctions.
