By harnessing the nonlinear response and fading memory effect of the p(g2T-T)-based IS-OECT array, we developed a stretchable reservoir computing system that achieved impressive image recognition accuracies of 90.81% and 90.65% at 0% and 100% strains, respectively.","PeriodicalId":19,"journal":{"name":"ACS Materials Letters","volume":"7 4","pages":"1394–1399 1394–1399"},"PeriodicalIF":9.6,"publicationDate":"2025-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143784992","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}

MXenes possess excellent structural and electrochemical properties, overcoming limitations like concentration polarization in conventional CDI electrodes and reducing energy consumption. This review discusses MXenes’ properties and various preparation strategies, including intercalating agents, surface modification, heteroatom introduction, and 3D structure design.

However, limited K+ insertion remains a bottleneck due to inadequate ion-insertion channels. Herein, we present an engineered g-C3N4 with expanded layer widths for facile ion diffusion, increasing K+ insertion by >250%. This leads to significant layer contraction post K+ insertion (∼3%, 1.5 times larger than before) due to stronger electrostatic attraction, resulting in weaker exciton binding energy (91 meV, ∼57% diminished), near-complete suppression of photoluminescence, and doubling of excited-state electron lifetime as revealed by femtosecond decay kinetics. These improvements led to ∼25 and ∼140 times increments over bare g-C3N4 in H2 and H2O2 production rates, respectively, under visible light. Considering the earth-abundant constituents of g-C3N4, our work establishes a novel design strategy for a highly active, sustainable photocatalyst.","PeriodicalId":19,"journal":{"name":"ACS Materials Letters","volume":"7 4","pages":"1385–1393 1385–1393"},"PeriodicalIF":9.6,"publicationDate":"2025-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143784963","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}

Previously, we identified disruptive dopants in Na–Mn–O that induced reversible oxygen redox. Here, we perform detailed mechanistic studies to understand why these dopants are effective. First, we confirm that no transition metals (TMs) are being oxidized─it is indeed oxygen redox. We also identify that reversible TM migration occurs in the P2 phase where reversible anionic redox occurs, while the migration is irreversible in the distorted P′2 phase. Structural control over the anionic redox is highly significant, but we further elucidate the role of the disruptive dopants. Localized oxygen holes are identified as the source of the reversible anionic redox, and these are deemed to remain stable due to the dopants minimizing the interactions between oxygens to prevent their dimerization. These important contributions to understanding anionic redox will help realize viable high-energy Na-ion batteries.","PeriodicalId":19,"journal":{"name":"ACS Materials Letters","volume":"7 4","pages":"1370–1377 1370–1377"},"PeriodicalIF":9.6,"publicationDate":"2025-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143784958","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}

In this work, by fine-tuning the layer stacking mode of two-dimensional MOFs, we successfully constructed a flexible material, FJI-W3-AB, which can amplify the diffusion-rate disparity between C3H4 and C3H6, achieving efficient kinetic separation. In contrast to FJI-W3-AA equipped with discrete intrinsic pores, FJI-W3-AB with dynamic guest-gated quasi-discrete pores is beneficial for regulating gas diffusion behavior. Ultimately, FJI-W3-AB not only exhibits significantly fast C3H4 adsorption kinetics but also achieves record C3H4/C3H6 kinetic selectivity.

Lubricating coatings show anti-icing potential but are limited by ice adhesion and durability. Here, we constructed a durable, low-adhesion matrix/lubricant (SBU/SO) anti-icing coating by introducing a B–O-bonded silicone resin. The SBU/SO coating not only had high hardness but also displayed long-term low ice adhesion strength (4.06 kPa). It was found that the exchange of B–O bonds enhanced chain slipperiness and accelerated the movement of the lubricant, which disrupted the formation of ice nucleation and weakened the interfacial force between ice and the SBU/SO coating. Consequently, the incorporation of B–O dynamic bonds significantly enhanced the impact resistance of the SBU/SO coating because the sacrificial bond effect of the B–O dynamic bond effectively protected the lubricant and inhibited its loss from the matrix resin.
