Lead-free ternary copper halides of the Cs–Cu–I system combine nontoxicity and air stability with bright luminescence arising from self-trapped excitons. In solution processing, the lack of solvent orthogonality makes it difficult to stack CsCu2I3 and Cs3Cu2I5 layers within a single device. Here, we adapt the molten salt evaporation concept, previously developed for lead-halide perovskite photovoltaics, to the Cs–Cu–I system through a vacuum molten salt deposition strategy. Premixed CsI and CuI form a homogeneous molten source that mitigates the disparate volatilities of the two precursors and enables compositionally coupled evaporation. Phase-selective X-ray diffraction, X-ray photoelectron spectroscopy, and optical characterization confirm that the 1:2 and 3:2 sources yield the targeted one-dimensional (1D) CsCu2I3 and 0D Cs3Cu2I5 films, respectively. Because the process is solvent-free, the two phases can be deposited sequentially between transparent PDMS spacers to form an encapsulated PDMS/CsCu2I3/PDMS/Cs3Cu2I5/PDMS core, and adding a spatially patterned, unencapsulated Cs3Cu2I5 dynamic layer on top yields an integrated label that combines three independent security primitives. First, macroscopic transparency provides physical stealth, revealing nothing to the naked eye. Second, spectral gating with 325 nm excitation and a 510 nm long-pass filter unmasks the yellow CsCu2I3 pattern beneath the intense blue Cs3Cu2I5 emission. Third, moisture triggers a reversible 0D-to-1D phase conversion of the dynamic layer that executes a localized bit-flip in the optical code. A standalone unencapsulated Cs3Cu2I5 film and the integrated label remain stable for 200 days in ambient air, the dynamic layer withstands 20 hydration–dehydration cycles, and the encapsulated core withstands 20 days of water immersion. By combining solvent-free, phase-selective deposition with multistimulus optical encoding, this work provides a lead-free multilayer platform for optical encryption.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"17 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2026-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149226007","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}

Here, we developed edible Jelly Fig (<em>Ficus awkeotsang</em> Makino, JF) pectin–alginate composite microgels (Mgel) through Ca²⁺-mediated ionic crosslinking as a gastrointestinal-responsive oral biomaterial. The resulting microgels exhibited uniform spherical morphology, enhanced mechanical robustness, gastric stability, and intestinal responsiveness, thereby improving the delivery performance of JF-derived bioactive components. Phytochemical and HPLC analyses showed that the ethanol-soluble fraction of JF was enriched in phenolic constituents and displayed potent antioxidant, anti-inflammatory, and epithelial barrier-protective effects in macrophage and intestinal epithelial cell models. In dextran sulfate sodium-induced colitis mice, orally administered Mgel showed superior protective efficacy compared with unformulated JF hydrogel at an equivalent dose, as evidenced by reduced body weight loss, disease activity, colon shortening, histological injury, inflammatory cytokine production, oxidative stress, and intestinal permeability. Mgel further restored mucus and tight junction barrier markers, promoted epithelial regeneration, and improved mucosal healing. Moreover, 16S rRNA sequencing combined with targeted metabolite profiling revealed that Mgel remodeled the gut microbiota, enriched beneficial taxa such as <em>Lactobacillus</em> and <em>Akkermansia</em>, and restored short-chain fatty acid and secondary bile acid metabolism.

The modification improves precursor wettability and are associated with denser perovskite films and reduced nonradiative recombination.

These findings link dysregulated mevalonate metabolism to pathological angiogenesis in MMD and support its role in endothelial dysfunction.

Here, we construct a Cu₇S₄/CuCo₂S₄ heterostructure in a single hydrothermal process, in which the two phases sharing a common Cu–S sublattice form a coherent interface within individual particles. By fixing the phase ratio independently through Rietveld refinement and benchmarking against both phase-pure constituents under identical conditions, we show that the composite exceeds the composition-weighted rule-of-mixtures prediction by a factor of 3.4 at 0.3 A g^–1. Because the constituents exhibit closely comparable charge–discharge profiles, the redox chemistry itself is unchanged, and this strongly super-additive response can primarily originate from the interface rather than from composition. Elemental mapping and surface-sensitive XPS, together with the coexistence of Li₂S and MgS in in situ XRD, further reveal that storage is spatially partitioned: Li⁺ converts the particle interior while Mg²⁺ reacts predominantly in the near-surface region, so that the two carriers occupy complementary regions of the same particle. Comparing APC-LiCl with APC-LiTFSI at matched salt concentration, and identical in every other respect, localizes the electrolyte effect to the electrode interface, where the chloride-containing system suppresses the progressive Mg-surface passivation that drives continuous overpotential growth in the TFSI^– system. The resulting cell delivers 400 mAh g^–1 at 0.3 A g^–1 and retains 152.56 mAh g^–1 after 330 cycles at 1.0 A g^–1 at ∼100% Coulombic efficiency.

Here, two phase-pure MnO2 polymorphs with contrasting crystallographic frameworks, α-MnO2 and δ-MnO2, were synthesized through surfactant-free routes and evaluated under comparable conditions. Tetragonal α-MnO2 with a 2 × 2 tunnel framework preferentially promoted oxygen evolution, whereas layered δ-MnO2 favored chlorine evolution. X-ray photoelectron spectroscopy revealed no detectable chlorine signal for α-MnO2 after chlorine evolution, while δ-MnO2 exhibited pronounced chloride-associated surface modification. Electron paramagnetic resonance spectroscopy and density functional theory calculations further revealed distinct defect characteristics and substantially different oxygen-vacancy formation tendencies between the two frameworks. These observations suggest that framework-dependent defect formation influences chloride-associated surface chemistry and contributes to the contrasting oxygen and chlorine evolution selectivity. Importantly, the selectivity trend was retained when the MnO2 phases were integrated onto iridium-ruthenium-based dimensionally stable anodes. These results demonstrate that contrasting crystallographic frameworks and their associated defect characteristics can markedly alter anodic selectivity and provide a structural basis for designing selective electrodes for chloride-containing electrochemical systems.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"75 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2026-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149225997","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}
