Solar steam generation is an efficient and sustainable technology for seawater desalination, yet challenges remain in balancing high evaporation efficiency, salt resistance, and environmental friendliness. Herein, we propose a recyclable evaporator (CA@FG) using discarded humidifier filter elements composed of cellulose acetate (CA) coated with graphite (FG) via a polydopamine adhesive. The CA@FG material exhibits superhydrophilicity and a solar absorption efficiency of 97.5a%, enabling rapid water transport and localized photothermal conversion. Under 1 sun illumination, the evaporator achieves a high evaporation rate of 2.35akg·m-2·h-1 and demonstrates exceptional cyclic stability with minimal performance degradation after 10 cycles in 10awt% brine. Furthermore, the vertical channels within CA@FG facilitate salt ion diffusion, effectively preventing surface crystallization even in concentrated saline solutions (15awt% NaCl). This work not only repurposes waste materials into high-performance evaporators but also provides a scalable and eco-friendly strategy for addressing freshwater scarcity and wastewater pollution. © 2025 Elsevier Ltd.

As a kind of battery that can work normally under deformation, flexible batteries are widely applied in wearable, portable and biomedical devices. However, the development and large-scale production of flexible batteries are restricted with the balance between the flexibility requirements and conductivity of the cathode. Modifying carbon-based materials used in cathodes is an effective means to address the poor electrochemical performance of flexible batteries. In this review, an extensive generalization about the preparation methods of cathode based on carbon materials including doping conductive materials, surface structure treatment, electrode macro-structure control, regulation of chemical properties, multilayer composite and treatment of carbon-based material precursors is enumerated. In addition, the modification of carbon-based materials in different types of batteries (zinc battery, lithium battery, supercapacitor, sodium battery and others) and batteries with different structures (1D, 2D and 3D) has been analyzed in detail. Finally, we have summarized the outlook section to provide some insights into the future prospects of cathode materials in flexible batteries. These discussions will offer more directions for the practical application of flexible batteries with superior electrochemical performance. © 2025

Engineering building blocks of covalent organic frameworks (COFs) with tailored active sites and microstructures is efficient in boosting capacitive energy storage. Herein we craft imine-linked COFs built from tri-arylamine knots and di-aldehyde linkers via a well-established Schiff-base condensation. The resulting COFs show enriched redox responses and diverse morphologies including nanoparticles, hollow spheres, and crystalline fibers by altering the knot planarity and the substitutes on linkers. It is disclosed that the coplanarity of building blocks and intramolecular H-bonding dominate the stacking modes of COFs, and accordingly their microstructures, and electrochemical performance. Among such COFs, a hydroquinone-enriched nanofiber-like COF delivers the highest specific capacitance of 235 F g-1 at 0.5 A g-1, which outperforms the most COF-based electrodes reported previously, due to its high planarity, intramolecular H-bonding, ultrahigh specific surface area, and abundant electroactive moieties. This work may unlock an alternative approach to the modularization of pseudocapacitive COFs by enriching redox-active centers and tuning microstructures. © 2022, The Authors. All rights reserved.

The emerging approach of in-situ polymerization of solid polymer electrolytes based on 1,3-dioxolane (DOL) has the advantage of low interfacial impedance and relatively high Coulombic efficiency with lithium anode. However, the DOL monomer conversion (C%) under Lewis acid catalysts need to be further improved, besides their alloying ability with lithium metal to generate protective interfacial layer has been ignored. Here, a Lewis acid catalyst In(OTf)3, which can not only achieve high C% (95.7%) at room temperature, but also react with lithium metal to form a stable LiF/LixIn-based composite SEI layer. The electrochemical test results show that the lithium ionic conductivity is as high as 7.1´10-4 S cm-1 at room temperature, the oxidation potential is over 4.5V, and the Li+ transfer number is up to 0.42. In addition, the Li/Li symmetrical cell assembled with this electrolyte can be stably cycled for more than 500 h at 3mA cm-2, with an over-potential of 178mv;X-ray diffraction results confirm the presence of In and In-Li alloy peaks that is formed by the reduction of In(OTf)3 with lithium metal. The assembled Li/LiFePO4 battery delivers specific discharge capacity and capacity retention rates of 115.5mAh g-1 and 85%, respectively after 300 cycles at 1C. Through the simple design, the dual-function electrolyte is prepared, which further broadens the design idea of solid polymer electrolyte © 2024, The Authors. All rights reserved.

Epoxy resin has been widely used in the field of bonding owing to its low shrinkage and high adhesive performance, especially room temperature cured epoxy resin has been paid more and more attention in the field of construction engineering. However, it is still a great challenge to ensure that the epoxy adhesive with low viscosity has a high mechanical strength during rapid curing at room temperature in some construction engineering fields, such as filling repair, bonding steel reinforcement, etc. In this work, low viscosity and high strength room temperature cured epoxy structural adhesives were fabricated by using 1,4-butanediol diglycidyl ether (BDE) with difunctional groups as active diluent to reduce the viscosity of bisphenol F epoxy resin (BPF-170) and four kinds of amines, namely 2,4,6-Tris(dimethylamiomethyl)phenol (TAP), Triethylenetetramine (TETA), N-Aminoethylpiperazine (AEP) and Isophorondiamine (IPDA) as curing agents at room temperature, following by the investigation of the effects of the four different chemical structures of curing agents on the gelation time and mechanical properties of epoxy structural adhesive. Among the four kinds of epoxy structural adhesives, the BPF-170/BDE/IPDA system using alicyclic amine has the lowest viscosity of 77 mPa·s and the longest gelation time of 95.9 min. Furthermore, the BPF-170/BDE/AEP system using piperazine amine has the best mechanical properties with the shear strength, tensile strength, compressive strength and impact strength of 23 MPa, 62.5 MPa, 112.9 MPa and 2.82 kJ/m2, respectively. In addition, the four epoxy structural adhesives have great thermal stability. The initial decomposition temperatures are all above 280 ℃ and the maximum decomposition temperatures are all above 360 ℃. These four epoxy structural adhesives with low viscosity and high strength have significant application value in the fields of construction engineering, joint filling and potting repairing, etc. © 2022, The Authors.

Titanium dioxide (TiO2) has been extensively used as an important photoanode material for photoelectrochemical (PEC) water splitting, but its activity is greatly hindered by the low charge transport and sluggish oxygen evolution reaction (OER) kinetics. Herein, we demonstrate spinel oxide NiCo2O4 (NCO) acted as both photothermal material and oxygen evolution cocatalyst could significantly promote the PEC performance of TiO2 photoanodes, and a high photocurrent of 2.34 mA cm-2 at 1.23 V vs. reversible hydrogen electrode has been achieved by NCO/TiO2 photoanodes assisted by photothermal effect. Importantly, a mechanism is proposed to explain the enhanced bulk charge transport and surface OER activity by an integrated various operando characterizations and density functional theory (DFT) study. Intensity modulated photocurrent spectroscopy (IMPS) analysis and DFT calculations imply the relatively high temperature induced by photothermal effect could accelerate small polaron hopping in the bulk of TiO2, which is verified by the electron diffusion coefficient variation of TiO2 with oxygen vacancies at different temperature. Operando cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS) reveal that photothermal conversion facilitates the oxidation of Ni2+ at lower potential and promotes the adsorption of *OH and deprotonation of *OOH intermediates. This work provides deep insight into the photothermal-enhanced PEC performance by observing the bulk small polaron hopping and surface dynamic evolution during the PEC process, which may underpin future advances in promoting PEC and photocatalytic performances of small-polaron-type semiconductors. © 2022, The Authors.

The phase compositions and microwave dielectric properties of Sn-deficient Ca2Sn2Al2O9 ceramics in this study were explored via crystal structure refinement, far-infrared reflectance spectral and microwave dielectric tests. The crystal structure of the Ca2Sn2Al2O9 was confirmed via transmission electron microscopy. The CaSnO3 and SnO2 second phases existed at Ca2Sn2-xAl2O9-2x (x = 0) ceramic. Single-phase Ca2Sn2Al2O9 ceramics were obtained at 0.08 ≤ x ≤ 0.1, and the orthorhombic structure with the Pbcn space group of Ca2Sn2Al2O9 was verified. For multi-phase Ca2Sn2-xAl2O9-2x (0 ≤ x ≤ 0.06) ceramics, their microwave dielectric properties were mainly affected by second phase contents, and their Q×f values increased gradually with the rise in x. High Q×f (105,700 GHz at 12.99 GHz) was obtained by the Ca2Sn2-xAl2O9-2x (x = 0.08) ceramic with high intrinsic Q×f (175,000 GHz). The large deviation between measured Q×f values and fitted intrinsic Q×f values could be ascribed to the Sn4+ vacancies of the Sn-deficient Ca2Sn2Al2O9 ceramics. The Ca2Sn2-xAl2O9-2x (0 ≤ x ≤ 0.1) ceramics presented large negative τf values, and this τf was mainly affected by τΕ. Meanwhile, the Ca2Sn2-xAl2O9-2x (x = 0.08) ceramic achieved optimal microwave dielectric properties (Εr = 8.31, Q×f = 105,700 GHz at 12.99 GHz and τf = ‒63.7 ppm/°C), indicating the good feature of this material for millimetre-wave applications. © 2022, The Authors.

Thermal insulation and high temperature resistant fabrics have important applications in aerospace, military and other fields. Quartz fiber has excellent mechanical properties and can resist high temperature. Aerogel materials have outstanding thermal insulation advantages, but there are deficiencies in mechanical properties. In order to effectively utilize the high temperature resistance of quartz fiber and thermal insulation advantages of aerogel materials. Firstly, a three-dimensional fabric structure of quartz fiber-aerogel multilayer composite was designed. Aerogel yarn and quartz yarn are woven into three-dimensional composite fabric by textile technology. The thermal insulation property of the composite fabric is improved effectively, and it has good anti-erosion performance at high temperature. Secondly, in order to explore the influence of internal structure of three-dimensional composite fabric on heat transfer performance, a full-scale three-dimensional simulation model was established, which can be used to predict the thermal insulation effect of composite fabric at 700 °C. Finally, the temperatures of different structural parts of the composite fabric were tested on a high temperature heating stage, and the thermal insulation effects of 300 °C, 400 °C, 500 °C, 600 °C and 700 °C predicted by the model were verified. The experimental results show that the fabric can effectively reduce the temperature of about 60%, and the difference between the measured data and the simulated data is less than 8%, which effectively verifies the accuracy of the model. © 2022, The Authors.

In this paper, we investigate the nonautonomous bright/dark solitons in a quasi-one-dimensional spin-1 Bose-Einstein condensates through a three coupled Gross-Pitaevskii (GP) system with space-time-dependent external potential and temporally modulated gain/loss distributions. Based on the Hirota bilinear method, we analytically construct the bright soliton solutions when the coupled GP system exhibits attractive interactions, while we obtain the dark soliton solutions when the coupled GP system exhibits repulsive interactions. The influence of spatiotemporal modulated external potentials, such as the gain/loss distribution Γ(t), on bright/dark soliton dynamics is analyzed in detail via the analytical solutions. By taking different Γ(t), we obtain different types of bright solitons, including periodic, dromion-like and parabolic solitons, and also derive dark solitons on different backgrounds, such as periodic, parabolic and kink backgrounds. We analyze the regulatory effects of different wavenumber ratios on the attraction and squeezing of bound-state solitons. Through the asymptotic analysis, we find that the interactions between two solitons are elastic. In addition, we conduct research on the forward and inverse problems of the above results via the parallel hard-constraint physical informed neural network (phPINN) method. The predicted solitons and potential functions are in good agreement with the exact solitons and potential in the system. © 2024, The Authors. All rights reserved.
