However, these properties often come at the expense of synthetic severity and recyclability. Here, we report the preparation of semi-fluorinated thermosets and thermoplastics via frontal ring-opening metathesis polymerization (FROMP), enabling rapid synthesis with minimal external energy input and no post-polymerization processing. Fluorinated monomers were prepared from pentafluoropyridine (PFP), whose activated heteroaromatic scaffold enables regioselective nucleophilic aromatic substitution with norbornene-derived nucleophiles. Alcohol-derived monomers intrinsically favored multifunctional reactivity and network formation, whereas 5-norbornene-2-methylamine formed a resonance-stabilized anilide adduct that suppressed further substitution. The resulting amine-linked fluoropolymers displayed linear architectures, favorable mechanical properties despite lacking covalent crosslinks, and improved prospects for reprocessability. Collectively, these studies position FROMP as a promising platform for more sustainable fluoropolymer manufacturing and end-of-life management.","PeriodicalId":19,"journal":{"name":"ACS Materials Letters","volume":"8 11","pages":"3187–3194"},"PeriodicalIF":8.6,"publicationDate":"2026-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149305701","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}

However, NFMO’s capacity is limited by the amount of sodium stored in its initial framework. Here, we show that direct contact presodiation is a facile way to introduce cyclable sodium into NFMO before cycling and increases first cycle desodiation to 241 mAh/g, exceeding its theoretical capacity. We characterize the structural and surface changes that occur during presodiation. We report full conversion to the Jahn–Teller distorted P′2 phase, NaFe0.5Mn0.5O2, before cycling using presodiation. Furthermore, a NaF, PF5–, and Na2CO3-rich interphase is created on PS-NFMO. With electrochemical impedance spectroscopy and distribution of relaxation times analysis, we show that the charge-transfer impedance contribution is reduced due to differences in interphase speciation of NFMO and PS-NFMO. Lastly, we show that a robust cathode electrolyte interphase is created during presodiation, which enables high coulombic efficiency (>90%).","PeriodicalId":19,"journal":{"name":"ACS Materials Letters","volume":"8 11","pages":"3261–3267"},"PeriodicalIF":8.6,"publicationDate":"2026-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149305726","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}

However, most reported oil-based inks still rely on acrylate-based cross-linking strategies, limiting the bio-based content and biocompatibility of the resulting printed materials. Here, we present a fully bio-based oil-derived DLP ink that exploits lipoates as photocross-linking units, thereby avoiding the use of acrylates and eliminating the need for photoinitiators. A lipoated triglyceride is synthesized and formulated into a 100% bio-based ink using ethyl lipoate as a reactive diluent and p-cymene as a solvent. The ink exhibits good curing performance and enables the fabrication of complex three-dimensional architectures, which can be depolymerized on demand. Cytocompatibility is demonstrated in a live/dead assay, with cell viability exceeding 97%. These results establish this fully bio-based system as a promising platform for the next generation of sustainable materials for biomedical applications.","PeriodicalId":19,"journal":{"name":"ACS Materials Letters","volume":"8 11","pages":"3202–3209"},"PeriodicalIF":8.6,"publicationDate":"2026-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149306044","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 present a tin disulfide (SnS2)-based memristor array that seamlessly integrates neuromorphic functionalities and reconfigurable physical unclonable functions (PUFs) within a unified hardware platform. The device employs layered SnS2 as the interlayer material, where intrinsic defect states and stochastic conductive-filament evolution govern the resistive switching behavior. Leveraging tunable analog conductance states and robust nonvolatile switching behavior, the memristor faithfully emulates synaptic plasticity and demonstrates high recognition accuracy in neuromorphic computing tasks. Meanwhile, the stochastic formation of conductive pathways during resistive switching generates unpredictable electrical responses, enabling robust and reconfigurable PUF functionality with strong resilience against machine learning attacks. This work provides a promising pathway toward secure neuromorphic hardware for future edge AI applications.","PeriodicalId":19,"journal":{"name":"ACS Materials Letters","volume":"8 11","pages":"3228–3236"},"PeriodicalIF":8.6,"publicationDate":"2026-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149305663","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}

By encapsulating Zn2+ in the vesicle lumen and triggering crystallization through external addition of membrane-permeable 2-methylimidazole, we establish a bioinspired compartmentalized synthesis approach. Confocal and electron microscopy confirm nanoparticle formation and reveal strong interactions between the precipitated phase and the membrane, leading to poration and selective content release.

Finite-element simulations incorporating the tailored arc architecture were conducted to analyze stress distribution and transformation behavior. The results reveal that enhanced transformation deformation along the chord-length direction promotes more stress-induced martensitic transformation, thereby amplifying the elastocaloric response.

Herein, a CuSCN hole transport layer and a trimetallic borate FeCoNiBi cocatalyst are integrated onto BiVO4 to synergistically address these bottlenecks. CuSCN forms a PN heterojunction with n-type BiVO4, generating a built-in electric field that extracts holes and suppresses bulk recombination. Meanwhile, FeCoNiBi accelerates OER kinetics and modulates surface states by passivating recombination centers and increasing intermediate surface states, promoting rapid hole transfer to the electrolyte. The optimized BVO/CuSCN/FeCoNiBi photoanode achieves a photocurrent of 5.82 mA cm–2 at 1.23 VRHE and retains 88.7% of its initial activity after 24 h.
