The optimized GPE system achieves an exceptional combination of properties: high ionic conductivity (3.3 × 10⁻³ S cm⁻¹ at 30 °C), outstanding Li⁺ transference number (0.79), and remarkable mechanical strength (3.9 MPa). Theoretical calculations and experimental analyses collectively confirm that the -CN groups competitively coordinate with Li⁺, restructuring the solvation environment to favor TFSI⁻ anion participation, thereby facilitating the formation of a robust solid electrolyte interphase (SEI) enriched with LiF and Li₃N.

Ferroptosis, an emerging form of iron-dependent programmed cell death, presents a promising treatment approach. However, its effectiveness is often hindered by adaptive resistance within the tumor microenvironment and inefficient drug delivery. To address these limitations, the glutathione (GSH)-responsive disulfide linker (-SS-) was utilized to engineer rhein (Rhe, chemotherapeutic agent) and ferrocene (Fc, ferroptosis booster) into the self-assembling small-molecule prodrug RSSF. Sorafenib (SOR), a ferroptosis inducer, was stably loaded into RSSF via a simple nanoprecipitation method, yielding the newly nanoprodrug designated as SOR@RSSF nanoparticles (NPs) for the combination therapy of TNBC. SOR@RSSF NPs exhibit markedly enhanced cellular uptake and enable the highly specific and synchronous release of Rhe, Fc, and SOR in response to intracellular GSH levels. Notably, Fc efficiently generates hydroxyl radicals (•OH) through the Fenton reaction, thereby inducing pronounced oxidative stress, while SOR concurrently impaired the cellular ferroptosis defense machinery. Combined with the chemotherapeutic activity of Rhe, the resulting lipid peroxide (LPO) accumulation and GSH depletion synergistically trigger both ferroptosis and apoptosis selectively in tumor cells. In a 4T1 tumor-bearing mouse model, SOR@RSSF NPs significantly inhibited tumor progression while maintaining a favorable biosafety profile. Overall, this study presents a promising ferroptosis-sensitizing strategy using a nanoprodrug delivery system for combination therapy against TNBC.</div></div>","PeriodicalId":351,"journal":{"name":"Journal of Colloid and Interface Science","volume":"710 ","pages":"Article 140048"},"PeriodicalIF":9.7,"publicationDate":"2026-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146130772","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, we propose a novel interlayer-confinement engineering strategy, utilizing spatially confined dual active sites in interlayer-confined dual single-atom-catalysts (iDSACs), to fundamentally break the intrinsic LSR by simultaneously manipulating reaction pathways and intermediate adsorption. Density functional theory (DFT) computations demonstrate that the synergistic space-electron effects enhance charge transfer, activate the O–O bond, and facilitate its dissociation. Further, tuning the confinement strength exerts opposing effects on various intermediates and catalysts. Consequently, this strategy effectively disrupts the LSR between *OOH and *OH adsorption, thereby improving OER and ORR activities. Additionally, an optimal interlayer distance of 7.0 Å is identified to balance dual-site synergy and steric effects, achieving low overpotentials (0.26 V for OER and 0.30 V for ORR on IrN₄).

Herein, we employ pre-intercalated K⁺ ions as structural mediators to modulate the interlayer H₂O content in hydrated V₂O₅, successfully synthesizing K_0.4V₂O₅·0.24H₂O (KVOH) with an optimized hydrated structure.

In this work, we develop a novel ethanol-mediated quenching reduction strategy synergistically integrated with rational two-dimensional structural engineering to precisely construct and stabilize Cu⁰/Cu⁺ pairs within a two-dimensional Cu-CuO/TiO₂ heterojunction (CTO-Q). The approach leverages the transient thermal energy generated during rapid cooling to initiate ethanol dehydrogenation, during which in-situ electrons are released and subsequently reduce Cu²⁺ ions, thereby facilitating the controlled formation and long-term stabilization of coexisting Cu⁰/Cu⁺ species. Advanced spectroscopic characterizations provide direct evidence for the successful generation and chemical state stability of the Cu⁰/Cu⁺ active sites. The resultant CTO-Q catalyst exhibits superior PMS activation capability, achieving 95% removal of levofloxacin within 30 min, with an observed rate constant (k_obs = 0.35 min⁻¹) that is 3.89-fold higher than that of the conventional catalyst. Remarkably, the catalytic performance remains nearly unchanged after five consecutive cycles, maintaining approximately 95% degradation efficiency, which underscores its exceptional operational stability—attributable to a self-sustaining redox cycle that mitigates irreversible oxidation. The generality and scalability of this synthetic strategy are further validated by the successful fabrication of a family of two-dimensional Cu-based heterojunctions (Cu-CuO/CeO₂, Cu-CuO/SiO₂, and Cu-CuO/Al₂O₃).
