This work successfully addresses device dependence on environmental humidity by developing a novel fiber with a core-sheath structure. The fiber features a platinum wire as the conductive core and a highly hydrophilic sheath (formed from hydrolyzed polyacrylonitrile, h-PAN) that actively captures ambient moisture. The outer layer is coated with a polypyrrole (PPy) semiconductor layer. When the fiber contacts a silver electrode, an interfacial electric field is generated at the contact dielectric. This field polarizes interfacial water molecules and drives directional ion migration, dynamically forming an asymmetric double layer. Collapse occurs when the double-layer structure separates. Through continuous mechanical motion, this process cycles repeatedly, thereby outputting stable direct current. Based on this principle, a single device delivers 300 µA current and 1.8 W m−2 peak power density at 75% relative humidity, maintaining stability during 200 days of intermittent testing. Through electrode optimization, output can be enhanced to 2 mA current and 73.6 W m−2 power density. The fiber can be directly woven into breathable fabrics and has successfully provided continuous power to devices like smartwatches. This research establishes a novel design pathway for developing high-power, environmentally adaptable wearable DC power generation systems.","PeriodicalId":86,"journal":{"name":"Materials Chemistry Frontiers","volume":" 11","pages":" 1881-1890"},"PeriodicalIF":6.4,"publicationDate":"2026-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148104187","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}

However, the lack of precise control over the swelling kinetics of hydrogels remains a challenge for constructing sophisticated actuation systems. Herein, we demonstrate reversible actuators with programmable folding kinetics by modulating the degree of microphase separation in hydrogels that possess an identical chemical composition—comprising thermo-responsive poly(N-isopropylacrylamide) (PNIPAM), N,N′-methylenebisacrylamide crosslinker, and nanoclay (NC) rheological modifier. We utilized extrusion-based 3D printing to align the NC, while microphase-separated structures were formed by inducing nucleation and growth of NC through the regulation of the PNIPAM polymerization rate. NC serves as a physical crosslinker within the hydrogel matrix, its association and dispersity directly influence water diffusivity and polymer chain mobility. Therefore, a hydrogel with fast swelling and deswelling kinetics can be fabricated by inducing a microphase-separated structure. The programmed folding kinetics are achieved by integrating hydrogels with distinct microphase separation degrees into hinge-based soft actuators with a bilayer structure. Specifically, soft actuators incorporating highly phase-separated hydrogels exhibited deswelling and swelling kinetics that are 1.6 and 4.4 times faster, respectively, than those of non-phase-separated ones. Leveraging such different kinetics profiles, a sequentially foldable multi-hinge strip and a gripper from a single-composition hydrogel system are successfully realized.","PeriodicalId":86,"journal":{"name":"Materials Chemistry Frontiers","volume":" 12","pages":" 1956-1965"},"PeriodicalIF":8.1,"publicationDate":"2026-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148261504","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}

To tackle this challenge, researchers are turning to advanced technologies that can both detect and remove waterborne pathogens such as viruses, bacteria, and fungi. Among these, two-dimensional (2D) nanomaterials, including graphene-based and phosphorus-based materials, transition metal dichalcogenides, MXenes, 2D metal oxides etc. have shown remarkable potential. Their unique features, including large surface area, adaptable electronic properties, and strong mechanical and chemical stability, make them highly effective for water treatment. This review focuses on the emerging role of 2D nanomaterials in the detection and elimination of waterborne pathogens. For pathogen sensing, we discuss advanced detection platforms based on surface-enhanced Raman scattering (SERS) and electrochemical sensing, highlighting how the distinctive electronic and plasmonic properties of 2D materials can significantly enhance signal sensitivity, selectivity, and detection limits. In addition to sensing, the review explores strategies for pathogen removal using 2D nanomaterials, with particular emphasis on adsorptive and photo removal approaches. Adsorptive removal relies on strong surface interactions between pathogens and functional groups present on the nanomaterials, while photo removal strategies utilize the photocatalytic activity of certain 2D materials to generate reactive species capable of inactivating or degrading microorganisms. Finally, we highlight key gaps and future directions, aiming to guide the development of next-generation 2D nanomaterial-based technologies for safe and sustainable water purification.","PeriodicalId":86,"journal":{"name":"Materials Chemistry Frontiers","volume":" 12","pages":" 1912-1946"},"PeriodicalIF":8.1,"publicationDate":"2026-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148261540","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}

To boost their performance, increasing the density of Fe–N–C active sites by incorporating more iron and/or modifying the local coordination structure to fine-tune the electronic properties of the sites have been key strategies. In this work, we present a highly active Fe–N–C electrocatalyst developed on a nitrogen and sulfur co-doped porous carbon substrate, derived from a polypyrrole (PPy) hydrogel. The precise selection of the complexing agent (SCN−) for Fe not only promotes sulfur doping and enhanced iron incorporation (up to 5.1 wt%) but alters the chemical environment of the Fe–N4 sites, yielding an Fe single-atom catalyst (Fe SAC) with excellent ORR activity in both alkaline and acidic environments. Besides demonstrating outstanding 4e− selectivity and tolerance to fuel cross-over the catalyst shows remarkable durability in accelerated stress tests and prolonged current–time response tests, making it a promising PGM-free option for sustainable energy technologies.","PeriodicalId":86,"journal":{"name":"Materials Chemistry Frontiers","volume":" 12","pages":" 2080-2088"},"PeriodicalIF":8.1,"publicationDate":"2026-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148261413","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}

Current NIR photodiodes exhibit higher photoelectric conversion efficiency than their counterparts operating in the visible light region. Integrating NIR scintillators with NIR optoelectronic conversion devices exhibiting high photoelectric conversion efficiency represents a promising solution for achieving efficient X-ray detection. However, almost all current scintillators are limited to the visible light region or exhibit poor performance. In this work, we achieve efficient NIR scintillation by doping Cs2ZrCl6 with d2 ions. The light yield (LY) of the sample is as high as 51 613 photons MeV−1, and the detection limit is as low as 192 nGyair s−1. The flexible scintillator film with an area of 10 × 10 cm2 prepared by combining the sample with PDMS can be successfully applied to X-ray imaging. The spatial resolution of the Cs2ZrCl6:Mo4+@PDMS scintillator screen was 10 lp mm−1, determined using standard X-ray resolution test panel imaging and MTF = 0.2.

Electrolyte additive engineering is a typical strategy for battery modification. However, highly polar additive molecules that can adsorb onto Zn electrodes tend to form strong reactions with Zn2+, resulting in an increase in the desolvation energy barrier for Zn2+. Herein, potassium perfluorobutanesulfonate (FSK) is introduced as an additive to construct a hydrophobic, Zn-friendly and strongly electronegative network in an electric double layer (EDL) on the Zn surface, which can homogenize Zn2+ flux and suppress side reactions, markedly extending cell lifetime. Meantime, the uniformly distributed and electron-withdrawing groups remain excluded from the primary solvation sheath, avoiding any penalty on desolvation kinetics. Such EDL regulation enables symmetric cells with FSK to cycle steadily for 1500 h at 1 mA cm−2 and 1 mAh cm−2 and delivers a high capacity retention in Zn‖V2O5 full cells over 1000 cycles. At a current density of 1 mA cm−2, the assembled Zn‖Cu half-cell operates for 1400 cycles (2800 h) with an average coulombic efficiency (CE) of 99.75%. This demonstrates that FSK markedly improves cell durability by homogenizing the Zn2+ flux, enabling smoother deposition and suppressing side-product formation. This work offers a new perspective on tailoring solvation structures and the EDL through ionic additives.","PeriodicalId":86,"journal":{"name":"Materials Chemistry Frontiers","volume":" 12","pages":" 1947-1955"},"PeriodicalIF":8.1,"publicationDate":"2026-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148261503","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}
