The prevailing view treats entropy as a performance-enhancing design parameter, assuming it improves activity by broadening active-site chemistries. This review reframes that view as an oversimplification, positioning entropy as a contingent design variable realized only when it resolves durability or robustness limitations beyond lower-entropy materials, not as a general-purpose performance multiplier. Tumor microenvironment constraints—acidity, hypoxia, redox imbalance, and glutathione abundance—limit conventional nanoagents' durability. Under such constraints, entropy-stabilized atomic heterogeneity can generate distributed active sites, electronic delocalization, and resistance to thiol-induced deactivation, enabling functional coexistence beyond compositional additivity. Multifunctionality introduces trade-offs: reduced selectivity, uncontrolled reactive oxygen species generation, and active-site interference. HEMs are justified only when entropy is essential for catalytic persistence under competing biological constraints, not when it merely correlates with improved activity in a single assay. Rigorous benchmarks—phase stability, durability, and lower-entropy comparators—should guide design toward safe, translational deployment.","PeriodicalId":19,"journal":{"name":"ACS Materials Letters","volume":"8 10","pages":"2817–2824"},"PeriodicalIF":8.6,"publicationDate":"2026-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149093688","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}

Biomaterial-assisted strategies hold the potential to address these challenges by providing an immune-isolated microenvironment and facilitating nutrient and oxygen supplementation. Therefore, this review outlines the primary bottlenecks in islet transplantation and then discusses current biomaterial engineering approaches to overcome them. Specifically, we summarize advanced encapsulation techniques utilizing diverse biomaterials for immune isolation and highlight tailored material designs aimed at mitigating drawbacks like foreign body reactions and increased oxygen diffusion distances. Furthermore, biomaterial-based methods to accelerate mass transfer and induce vascularization for enhancing islet survival are discussed. Finally, future development trends in biomaterials for islet encapsulation and transplantation are prospected. This review is expected to provide valuable insights into biomaterial design strategies, inspiring innovative solutions for treating T1DM through improved islet encapsulation and transplantation.","PeriodicalId":19,"journal":{"name":"ACS Materials Letters","volume":"8 9","pages":"2462–2489"},"PeriodicalIF":8.6,"publicationDate":"2026-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148923766","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 employ X-ray diffraction, Raman spectroscopy, and solid-state NMR to monitor the phase evolution during sintering. Owing to the high volatility of P2S5, stoichiometric imbalance occurs during heating, leading to impurities. By conducting the reaction in a sealed container with a suitable excess of P2S5, phase-pure LPSC is obtained, which exhibits an ionic conductivity of 3.2 mS cm–1. Moreover, standardized procedures for ionic conductivity measurements and all-solid-state battery testing are established. The LPSC-based battery with an NCM613 cathode and Li–In anode delivers a capacity retention of 96.6% after 260 cycles at 0.1C. This work clarifies the synthesis chemistry of argyrodite electrolytes and offers a scalable route to high-performance sulfide solid electrolytes.","PeriodicalId":19,"journal":{"name":"ACS Materials Letters","volume":"8 9","pages":"2798–2806"},"PeriodicalIF":8.6,"publicationDate":"2026-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148923827","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}

Here, we develop a fully automated three-dimensional piezoresponse force microscopy (Auto-3DPFM) technique, which integrates all essential steps in interferometric PFM for 3D polarization vector characterization, including laser alignment, tip calibration and approach, image acquisition, polarization vector reconstruction, and visualization. The automation reduces the experimental burden of ferroelectric polarization vector characterization, while continual calibration ensures consistency and reproducibility of 3D polarization reconstruction. An algorithmic workflow is also developed to identify domain walls and calculate their characteristic angles via a spatial vector-angle-difference method, presenting one capability enabled by Auto-3DPFM and inaccessible through traditional PFM techniques. When integrated with machine learning and adaptive sampling strategies in self-driving labs, Auto-3DPFM serves as a valuable tool for advancing ferroelectric physics and microelectronics development.","PeriodicalId":19,"journal":{"name":"ACS Materials Letters","volume":"8 9","pages":"2672–2680"},"PeriodicalIF":8.6,"publicationDate":"2026-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148915736","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}

This review evaluates the ongoing transition toward sustainable 3D printing and identifies a critical “functionalization paradox”: the chemical modifications required to make bio-derived feedstocks printable often increase their carbon footprint and compromise their inherent biodegradability. Herein, we categorize sustainable materials through a two-pronged circularity roadmap. First, after reviewing bio-based functionalized monomers, we review inherently reactive bio-monomers, such as lipoic acid derivatives, which bypass synthetic modification to enable rapid polymerization and closed-loop chemical depolymerization. Second, we review covalent adaptable networks (CANs) as a potential solution for thermosets that require synthetic functionalization, providing a pathway to reprocessability. Finally, we conclude that achieving truly circular 3D printing requires a fundamental shift in design philosophy: moving from the functionalization of biomass to the exploration of natural molecular architecture and dynamic network topologies.","PeriodicalId":19,"journal":{"name":"ACS Materials Letters","volume":"8 9","pages":"2490–2513"},"PeriodicalIF":8.6,"publicationDate":"2026-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148915738","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}

Nevertheless, large-scale conformational changes with high geometric precision and efficiency remain major challenges. Herein we report a topologically engineered DNA origami that undergoes a dramatic transformation from a flexible, shape-indeterminate polygon into a fixed sharply angled rhombus. The DNA quadrilateral nanostructure is first built from a six-helix bundle backbone incorporating three hinge regions to confer mechanical flexibility. Sticky ends at opposing corners are designed as programmable docking domains. A facile catalytic hairpin assembly (CHA) circuit triggered by target miRNA generates duplex lockers that bridge these docking domains, collapsing the DNA quadrilateral into a locked conformation of sharply angled rhombus. Such geometry brings adjacent Cy3−Cy5 couples within the Förster distance. Fluorescence spectra are thus analyzed, which provide a quantitative readout of target miRNA information. A generalizable strategy is established for linking molecular recognition to large-scale DNA nanostructural reconfiguration.","PeriodicalId":19,"journal":{"name":"ACS Materials Letters","volume":"8 9","pages":"2572–2579"},"PeriodicalIF":8.6,"publicationDate":"2026-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148923715","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, existing multistate switching primarily relies on either cascading multiple binary devices or utilizing magnetic domain wall motion, suffering from structural complexity, weak read signals, and high energy consumption. Our theoretical study presents a Pt/NiF2/Pt trilayer model based on a noncollinear antiferromagnet with four degenerate ground states, whose advantage is its electrically controlled four-state switching within a single device. This four-state switching simulates the synaptic functions of long-term depression and long-term potentiation. The artificial neural network built on the trilayer model achieved a recognition rate of 99.5% in retraining for digit recognition tasks while realizing low power consumption and high integration. This study demonstrates that multistate antiferromagnet-based spin-orbit torque device models provide a promising theoretical route for brain-inspired computing.","PeriodicalId":19,"journal":{"name":"ACS Materials Letters","volume":"8 9","pages":"2655–2662"},"PeriodicalIF":8.6,"publicationDate":"2026-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148923726","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}
