However, recent review mostly focuses on photothermal materials' design and the mechanisms for reducing evaporation enthalpy, with limited discussion on diverse substrates, physicochemical properties of hydrogels, and thermodynamic analysis during the PISSG. This work aims to systematically review the current progress of hydrogel-based PISSG and the challenges in practical applications. It begins with the classification of hydrogels on different substrates, mainly including cellulose, polyvinyl alcohol, polyacrylamide, and sodium alginate. Subsequently, the properties of hydrogels, photothermal conversion mechanism, and thermodynamics of interfacial evaporation are highlighted to illustrate how hydrogels optimize PISSG. Furthermore, the practical applications, ranging from seawater desalination, wastewater purification, photocatalytic degradation, multiple energy harvesting and conversion, and sterilization are broadly presented. Finally, the future research directions are proposed. Through this review, a comprehensive understanding of hydrogel-based evaporators in PISSG is proposed to address potential issues in both fundamental research and practical applications, thereby contributing to the resolution of global water scarcity challenges.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"102 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2025-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144269343","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Aqueous redox flow batteries (ARFBs) have emerged as a promising technology for long-duration, grid-scale energy storage due to their advantages in safety, scalability, and independent tunability of power and energy capacities. Enhancing energy density is crucial for reducing system costs and facilitating large-scale deployment. In this review, key parameters and strategies for boosting the energy density of ARFBs are summarized, including optimizing material solubility and electron-transfer capabilities, developing novel redox pairs, and improving system design to reduce polarization losses. Despite significant progress, challenges remain—such as developing suitable materials, the optimal matching of electrodes, electrolytes, and membranes, and scaling systems for industrial applications. Advanced characterization tools, AI-driven simulations, and continued research on new materials and system engineering will be essential for overcoming these barriers.

However, the ionic nature with high surface energy and metastable structure of PQDs limits the stability. Here a facile approach is reported for realizing stable CsPbBr3 PQDs based on ion-dipole interaction, in which ammonium bromide is used as a bromine source to achieve the regulation of PQDs precursor and tri(o-tolyl) phosphine is utilized as a short-chain ligand to modulate the ligand composition on the surface of PQDs. By the synergistic effect of precursor and long/short-chain ligands, bright CsPbBr3 PQDs are synthesized with a near-unity photoluminescence quantum yield and long TRPL lifetime of 285.98 ns. More importantly, the CsPbBr3 PQDs show excellent long-term stability toward water, light, and heat, in which the initial fluorescence intensity can remain 80% after dispersion in water for 7 days and 82% underhigh-temperature treatment at 433K. Further, highly efficient perovskite electroluminescent light-emitting diodes (PeLEDs) are constructed with a maximum external quantum efficiency (EQEmax) of 25.88%. This established strategy achieves the EQEmax record for PeLEDs prepared from bulk-modified CsPbBr3 PQDs, and breaks the barrier between simultaneously improving material stability and device efficiency, providing a powerful platform for the future development of high-quality PQDs with significant applications.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"28 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2025-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144252870","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The doping-free MoTe2 complementary inverter array performs robust logical operations with excellent uniformity.

Digital light processing (DLP)-based stereolithography has been widely adopted by material scientists, and DLP printers are now commonly available. However, despite its innovative nature, 3D printing remains limited in terms of material compatibility, which has largely been restricted to organic polymers and their composite derivatives. The direct printing of inorganic and functional structures remains challenging. To expand the potential of 3D printing to a broader spectrum of emerging materials, a new type of inks based on photo-cross-linkable nanoparticles is developed. Specifically, silica nanocages functionalized with methacrylate ligands enable the direct printing of mesoporous silica monoliths, eliminating the need for additional organic binders or calcination. Innovative functionalized inks are further developed by adding metal salts (Co, Ni, Cu, and Pd) into the silica inks allowing the selective positioning of different metallic zones along a monolith. In addition, a complementary strategy is presented for the in situ growth of microporous metal-organic frameworks (HKUST-1) within printed mesoporous silica monoliths. These fabrication strategies pave the way for designing hierarchical architectures suitable for a wide range of catalytic and environmental applications, including reactors for cascade reactions and CO2 capture.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"60 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2025-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144252868","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nevertheless, the rational design of ARCs with hierarchical gradient refractive index (GRIN), particularly the further integration of liquid repellency and mechanochemical durability, remains a significant challenge. Here, a computational-experimental synergistic paradigm that concurrently optimizes optical gradients and surface functionalities to address these limitations is demonstrated. Finite-difference time-domain (FDTD) simulations are employed to rationally optimize the size of silica nanoparticles (SNs) for broadband suppression of angular-dependent reflection and scattering. Guided by theoretical modeling, the refractive index profile of SNs is precisely modulated within a tri-layer designed GRIN configuration to facilitate interfacial phase coherence. A fluoride-free omniphobic modification is introduced via sequential silane vapor deposition and subsequent polysiloxane grafting. This functionalization endows the liquid-repellent GRIN antireflective coating (LGAC) coated glass with a peak transmittance of ≈99.5% within the visible spectrum, while simultaneously imparting self-cleaning properties. Furthermore, LGAC contributes to a relative PCE enhancement exceeding 7.1% in PV cells. Its exceptional mechanochemical durability positions it as a promising candidate for enduring performance enhancement and protection of PV panels under variable environmental conditions.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"92 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2025-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144252873","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, hollow Fe2O3/CoSe2 heterostructures (H-Fe2O3/CoSe2@C) via interface engineering are reported as highly effective EOR promising electrocatalysts. Characterizations reveal that Fe2O3 functions as a dynamic electron spring to tune the electronic structure of Co sites, accelerating the formation of the Fe2O3/CoOOH heterostructure while suppressing Fe2O3/CoO2 evolution. In situ Raman spectroscopy and theoretical calculation confirm that the Fe2O3/CoOOH heterostructure enhances EOR kinetics and lowers the energy barrier of the potential-determining step. Quasi in situ X-ray photoelectron spectroscopy further demonstrates that Fe2O3 stabilizes Co3+against overoxidation, expanding the operational potential window. Consequently, H-Fe2O3/CoSe2@C achieves outstanding EOR performance, exhibiting 10 mA cm−2 @1.30 V vs. RHE with a high faradaic efficiency of 99% at 1.30 V. Ethanol-assisted Zn-Air battery/water splitting devices based on H-Fe2O3/CoSe2@C demonstrate enhanced energy conversion efficiency, with voltage reduced by 210 and 180 mV at 10 mA cm−2, respectively.

However, their development is hindered by the limited availability of suitable anode materials. Herein, we propose for the first time the use of a topological insulator, bismuth telluride (Bi2Te3), as a novel anode material integrated onto a 3D printed nanocarbon electrode (3DpCE) for NH4+ ion storage. Taking advantage of the 3D porous framework and the non-metallic nature of NH4+ ions, Bi2Te3@3DpCE exhibits a higher discharge capacity of 128 mAh g−1 at 0.5 A g−1 with lower polarization, and better cycling stability compared to metallic ions such as Li+ and Na+. Through various ex-situ characterizations, we also reveal the plausible NH4+ storage mechanism.

The CuHCF@3DpCE//Bi2Te3@3DpCE full cell in 1 M (NH4)2SO4 electrolyte delivers a high energy density of 134.8 Wh kg−1 and a power density of 1800 W kg−1, outperforming previously reported AIBs.
