Its clinical translation, however, remains more limited than the scale and sophistication of the field might suggest, particularly when targeted systemic delivery is required. In the recent past, others have highlighted those limitations, however, what concerns us is that some of the assumptions that constrained earlier generations of nanomedicines are now re-emerging in AAV-based gene therapy and in vivo CAR-T platforms. More precise payloads do not make delivery more precise, nor do viral vectors escape the biological barriers encountered by synthetic nanoparticles. In this Perspective, we revisit the liver paradox, the distinction between organ accumulation and functional delivery, the protein corona and the promise of biomimetic systems. Our intention is not to add another catalogue of limitations, but to ask what should change. We argue that the next phase of drug delivery should be less focused on adding complexity to the carrier and more committed to quantifying its biological journey.","PeriodicalId":114,"journal":{"name":"Advanced Materials","volume":" ","pages":"e75364"},"PeriodicalIF":29.1,"publicationDate":"2026-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149178190","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, their controlled engineering, including tuning lateral domain size and integration into vertical van der Waals heterostructures with other 2D materials, remains challenging. Here, we present a facile route for the synthesis of two types of heterostructures (HSs), consisting of monolayers (MLs) of MoSe2 and WSe2—purely lateral (HS I) and hybrid lateral/vertical (HS II)—using liquid precursors of transition metal salts and chemical vapor deposition (CVD). Depending on the growth parameters, the heterostructure type and its lateral dimensions can be adjusted. We characterized properties of the HS I and HS II by complementary spectroscopic and microscopic techniques, including Raman and photoluminescence (PL) spectroscopy, optical and atomic force microscopy (AFM), and scanning and transmission electron microscopy (TEM). The PL measurements reveal strong interlayer exciton (IE) emission in the MoSe2/WSe2 region of HS II, which dominates the spectrum at 4 K and persists up to room temperature (RT). These results demonstrate high optical quality of the grown HSs, which in combination with the scalability of the developed approach, pave the way for fundamental studies and device applications based on these unique 2D quantum materials.","PeriodicalId":114,"journal":{"name":"Advanced Materials","volume":"38 57","pages":""},"PeriodicalIF":29.1,"publicationDate":"2026-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/adma.74172","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148589557","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, conventional ion-pair-based PEM fuel cells suffer from performance degradation and unstable proton transport at temperatures above 160°C. In this study, a cross-linked ion-pair microporous polymer, poly(spirobisindane-co-terphenyl piperidinium) (C50-PSTP-x), is simultaneously used as both the PEM and catalyst-layer ionomer, achieving a strong acid anchoring effect across the entire membrane electrode assembly. The polymer integrates ion-pair-coordinated PA-cyclic quaternary ammonium groups, a spirobisindane backbone with intrinsic microporosity, and a highly roughened cross-linked structure.

The efficient recovery and purification of these gases are still challenging despite their significant industrial and domestic relevance. They exist in the gaseous state under ambient temperature and pressure and are typically recovered from natural gas streams containing multiple close-boiling-point hydrocarbons. So far, cryogenic distillation is the commonly used method for their separation and purification. It operates based on their boiling-point differences, which amounts to significant energy consumption. To address this limitation, adsorption-based technology is considered an energy-efficient alternative for the purification of light hydrocarbons. To this effect, polymeric sorbents such as porous polymer networks (PPNs) are a potential alternative due to their robustness, stability, and scalability. This review provides an extensive discussion on cryogenic distillation, applications of light hydrocarbons, and progress in light hydrocarbon purification using polymeric sorbents. Additionally, the pore structure, stability, and techno–economic feasibility of the polymeric sorbents were extensively examined, covering current progress, mechanism of guest molecule separation, characterization techniques, and hurdles still encountered. Overall, since their application in light hydrocarbon separation is still an evolving field, this review will facilitate robust designs by providing the necessary know-how and roadmaps needed for advancement.","PeriodicalId":114,"journal":{"name":"Advanced Materials","volume":"38 57","pages":""},"PeriodicalIF":29.1,"publicationDate":"2026-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/adma.74471","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148700221","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here we report a proton-mediated coordination equilibrium that enables nonfreezing Zn2+ transport in hydrogel electrolytes under ultralow-temperature conditions. By coupling phytic acid with zinc phytate, proton activity and Zn-O coordination are dynamically balanced, continuously reconstructing the local hydration environment to suppress hydrogen-bond ordering, stabilize bound water, and prevent water crystallization. Simultaneously, reversible coordination exchange sustains Zn2+ dissociation and migration through a hopping transport mechanism. At the Zn anode, proton-mediated interfacial evolution drives the formation of a ZnS/Zn3(PO4)2-rich hybrid interphase that accelerates interfacial kinetics and suppresses degradation. Consequently, the optimized electrolyte achieves an ionic conductivity of 2.4 mS cm- 1 and an apparent Zn2+ transference number of 0.24 at -60°C, enabling Zn||Zn cells to cycle stably for over 3400 h and Zn||PANI full cells to retain 60.1% of their capacity after 4000 cycles at -60°C. These findings identify proton-mediated coordination equilibrium as a general mechanism for preserving ionic transport in frozen aqueous environments and provide a blueprint for low-temperature electrochemical energy storage.","PeriodicalId":114,"journal":{"name":"Advanced Materials","volume":" ","pages":"e75379"},"PeriodicalIF":29.1,"publicationDate":"2026-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149178181","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}

Here we report Au@Se core-shell colloidal pigments in which a plasmonic Au core is embedded within a visible-range Mie-resonant Se shell. The key signature is not the gradual red shift expected from passive dielectric loading, but an asymmetric hybrid feature with compressed linewidth, consistent with Fano-like interference between the broad electric-dipole response of the Se shell and the narrower Au-core electric-dipole response. The hybrid mode yields Q factors up to ≈15 in freely dispersed colloidal pigments, producing narrow transmission windows and spectrally separated reflection bands from the same liquid dispersion. By independently tuning the Au core diameter and Se shell thickness in a benchtop synthesis, we achieve broad visible color tuning in transmission and reflection and enlarge the accessible international commission on illumination chromaticity (CIE) area relative to single-component Au or Se colloids. The particles are formulated into ultraviolet (UV)-curable resins and writing inks for 254-ppi color filters, freeform paper deposition, and polarization-selective readout.

Here, using electron ptychography in combination with a suite of experimental and theoretical methods, we show that ScAlN films (with x spanning 0.18 to 0.36) contain nanoscale Sc-rich clusters which maintain the wurtzite crystal structure. While both molecular beam epitaxy (MBE) and sputter deposited Sc0.3Al0.7N films show Sc clustering, the degree of clustering is significantly stronger for the MBE-grown film, offering an explanation for some of the discrepancies between MBE-grown and sputtered films reported in the literature. Moreover, the MBE-grown Sc0.3Al0.7N film exhibits a dispersive and anomalously large dielectric permittivity, roughly double that of sputtered Sc0.3Al0.7N. We attribute this result to the Sc-rich clusters locally reaching x ∼ 0.5 and approaching the predicted ferroelectric-to-paraelectric phase transition, resulting in a giant (local) enhancement in permittivity.

Nevertheless, leveraging the gut microbiome as an interventional strategy has recently gained traction, especially in patients on immune checkpoint inhibitor (ICI) therapy. Here, microbial-derived double-layered membrane vesicles are developed as adjuvants and cell-free carriers, fused with cell-penetrating peptide-modified antigens, and encapsulated in an alginate/chitosan-microsystem to engineer oral vaccines. This design strategically harnesses the crosstalk between the gut microbiome and gut-associated lymphoid tissues, driving dendritic cell maturation, plasma cell activation, and production of immune-stimulatory cytokines within the mesenteric lymph nodes and lamina propria. In mouse prophylactic and therapeutic tumor models, the select Bifidobacterium bifidum-derived oral vaccine combined with anti-PD1 treatment enhances cytotoxic antitumor responses, along with Th1-, Th17-immunity, leading to potent tumor suppression, prolonged survival, and long-term protection against tumor rechallenge. Mechanistically, the vaccine promotes interferon-γ-producing T cells and antitumor efficacy with ICI therapy via the improved microbiota diversity and signaling metabolites, with an indole-3-acetic-acid (3IAA) enriched diet profoundly shaping T-cell recruitment and differentiation.
