Corrosion and leakage of molten salt pose significant challenges to the implementation of high-temperature packed-bed latent heat storage in concentrating solar power. This work proposes a novel material-system integrated solution for high-temperature (> 500 °C) packed-bed latent heat storage. Shape-stabilized phase change material (ss-PCM) made by cold-pressing and hot-sintering serves as the “core” of the thermal storage capsule, achieving high thermal stability and excellent corrosion resistance at high temperatures. By controlling the particle size of the SiC, ss-PCMs exhibit a high thermal conductivity of 1.81–5.45 W/(m·K). The effective thermal storage density is 1213.46 kJ/kg within the 50–700 °C range. Furthermore, the thermal performance and pressure drop of the five configurations are analyzed using a 3D model that accounts for radiation effects. The results indicate that reducing capsule height with staggered stacking significantly increases the average charging power (by 29.8% compared to Case 1) and shortens the charging time, but raises the pressure drop. Case 5 (with reduced diameter) is recommended as the optimal design, achieving a 21.8% power improvement (compared to Case 1) while maintaining a manageable pressure drop. This work offers a promising approach for scaling up high-temperature packed-bed thermal storage in renewable energy integration, contributing to enhanced renewable energy utilization.

Biomass-based self-healing triboelectric materials are recognized for meeting the sustainability and reliability demands of flexible electronic sensors, playing an essential role in enhancing device durability and operational longevity. However, existing self-healing biomass systems still face challenges in achieving synergistic enhancement of both mechanical properties and self-healing efficiency. Inspired by the strong adhesion of mussel foot proteins, a robust, room-temperature self-healing, and recyclable biomass-based triboelectric material has been developed through the synergistic coordination of supramolecular interactions (such as Fe 3+ ─catechol coordination bonds, hydrogen bonds, and π─π stacking) and nanoconfinement. The constructed nanonetwork was found to facilitate enhanced energy dissipation and accelerated dynamic bonds reorganization, resulting in a combination of superior mechanical properties and efficient self-healing. The obtained material demonstrated a tensile strength of 30.95 MPa, a toughness of 100.77 MJ m −3 , and a remarkable self-healing efficiency of 96.22%. A triboelectric tactile sensor fabricated from this material exhibited a rapid response of 14 ms, and when integrated with deep learning algorithms, achieved highly accurate identification of material types and surface textures. This work offers a promising approach for the development of bionic perception systems in complex environments.

Four-electron transfer process of oxygen evolution reaction (OER) has become a bottleneck restricting water electrolysis, due to its inherently high kinetic energy barrier. Therefore, the exploration for high-efficiency and long-term stable non-noble metal OER catalysts is crucial for sustainable energy conversion. This work designs a molten salt-mediated ball milling-pyrolysis stepwise treatment to synthesize spongy V 2 O 5 composite Fe-intercalated graphitic nitrogen (N–V 2 O 5 @FeC). Specifically, Fe-intercalated graphite is achieved using the FeCl 3 /KCl molten salt system, a highly conductive FeC substrate being constructed accordingly. Then, NH 3 generated from melamine pyrolysis enables spongy porous structure construction and N-doping. N–V 2 O 5 @FeC catalyst possesss the following advantages: First, spongy porous structure greatly increases exposure of active sites, while Fe intercalation-induced graphite edge defects and Fe–O–V bonds jointly enhance active site density of V 2 O 5 composite, thereby boosting catalyst activity. Second, N-doped carbon network improves electron transport performance, enabling catalyst's charge transfer resistance decline to 19.9 Ω. Moreover, dual stabilization mechanisms of Fe–O–V stable structure and chemical anchoring of V–O–C bonds endow the material with good structural stability under alkaline conditions. In detail, N–V 2 O 5 @FeC reaches 10 mA cm −2 current density at only 299 mV overpotential in alkaline solution, with low Tafel slope (53.0 mV dec −1 ) and 50-h stability.

New nanofiltration membrane with larger volume output is one of the key parameters for selection in drinking water treatment applications. Moreover, evaluating the separation performance of NF membranes is crucial for ensuring the continued safety of effluent water quality when responding to sudden changes in water quality. In this study, the melamine, a highly reactive monomer containing a triazine ring, participates in the interfacial polymerization reaction between the piperazine and 1,3,5-benzenetricarbonyl trichloride, thus providing an opportunity to tune the polyamide layer properties. The reaction with melamine changes the structural parameters and decrease the diffusion rate of piperazine, while introducing more intermolecular hydrogen bonds in new hybrid polyamide layer compared to the conventional polyamide layer. These strong intermolecular hydrogen bonds are crucial for enabling high Na 2 SO 4 rejection in melamine-modified membranes. This strategy resulted in membrane permeance of 2.5 times that of commercial membranes (VNF1 and NF270) and unmodified membrane in a complex mixed salts solution, with Cl − /SO 4 2‒ selectivity factor increasing form 7.5 to 44.6. Furthermore, the new membrane can remove most dissolved substances from ultrafiltration effluent in treating drinking water source (Hulukou Reservoir) impacted by sudden shale gas wastewater spill, ensuring the safety of the treated water. The purified water quality parameters are inferior to those of the VNF1 and NF270 membranes, but slightly superior to the unmodified membrane. However, water recovery experiments revealed that all membranes suffered from severe scaling issues. Overall, the results suggest that melamine may be utilized to tune the performance of nanofiltration membrane through the scalable one-step polymerization procedure, providing an effective strategy for preparing high-performance membranes.

Illegal addition of curcumin (Cur) in food poses a significant public health threat, creating an urgent need for sensitive, reliable detection methods. In this work, dual-emission carbon dots (DCDs) were synthesized via a one-step hydrothermal method with Rose Bengal and melamine as raw materials. Based on the distinct fluorescence responses of DCDs to Cur at two characteristic wavelengths, a novel ratiometric fluorescence sensor for Cur detection was constructed. The emission at 432 nm is primarily governed by inner filter effect, while quenching at 532 nm is associated with the fluorescence resonance energy transfer. The sensor shows a robust linear range of 0.1–20 μM with a limit of detection of 0.089 μM. The sensor was successfully employed for the detection of Cur in various food samples, including chili, ginger, and mustard powder, achieving recovery rates between 92.75% and 110.00%. This work enriches CDs synthesis strategies and provides a sensitive, cost-effective, rapid method for Cur detection, supporting food industry monitoring needs.

This work introduces an innovative stacked iron mesh electrode configuration to achieve accelerated degradation of perfluorooctanoic acid (PFOA) by synergistically coupling electrochemical oxidation with peroxymonosulfate (PMS) activation. The system was systematically evaluated through electrochemical measurements, free radical quenching, and electron paramagnetic resonance spectroscopy, complemented by density functional theory calculations. The optimized triple-layer Fe electrode demonstrated outstanding performance, attaining nearly complete PFOA removal (100 %) within 12 min and a high kinetic rate constant of 0.218 min –1 . DFT analysis revealed that the Fe mesh possessed the strongest PMS adsorption energy (–2.68 eV) and the shortest Fe–O bond length (2.24 Å), confirming its superior activation capability. Mechanistic studies confirm the effectiveness of the electron transfer coupled with the hydroxyl radicals in defluorination and decarbonization during PFOA degradation. In addition, the system exhibited high cycle stability and strong tolerance to various background ion under continuous operations in the amplification experiment. The system also exhibited superior performance and low leaching of metal ions in treating various organic pollutants of practical wastewater (fluoride wastewater and landfill leachate). These findings present an effective and practical strategy for the remediation of persistent per- and polyfluoroalkyl substances in contaminated water sources.

Single-crystalline ultra-fine sized LiNi x Co y Al 1-x-y O 2 (NCA) features stable Al─O bonds and crack-resistantance due to no grain boundaries, exhibiting excellent long charge–discharge cycle stability as a lithium-ion battery cathode. With flexible electronics growing, flexible energy storage materials are urgently needed. However, preparing single-crystalline ultra-fine NCA particles and assembling them into a self-supported superflexible cathode is still a tough challenge. Here, submicron-sized Ni-rich LiNi 0.89 Co 0.09 Al 0.02 O 2 single-crystals were made via a molten-salt-assisted high-temperature solid-phase method with lithium added during annealing. Then, they were combined with carbon nanotubes by directional pressure filtration to form a superflexible porous hybrid buckypaper (BP). Under O 2 , sintering at 750°C for 15 h with 1.03 Li addition and annealing with a Li source at 750°C for 5 h gave the optimal submicron-sized NCA single crystals. The BP could curl around a 2 mm-radius rod, bend 180°, knot without damage, and had 9.59 MPa tensile strength. In a lithium-ion battery, at 1C, its initial and 200-cycle capacities were respectively 192.27 and 179.3 mAh/g (93.2% retention); at 5C, respectively 135.4 and 132.9 mAh/g (98% retention). This work offers a new idea for self-supported flexible cathode construction.

Oxygen vacancy-rich Bi 12 O 17 Cl 12 /BiOBr S-scheme heterojunction was successfully constructed through a solvothermal and ethylene glycol-assisted coprecipitation method. Benefited the construction of S-scheme heterojunction structure and the introduction of oxygen vacancy, the separation efficiency of photo-induced carriers is promoted. Under the optimized conditions (catalyst dosage 0.2 g/L, CIP concentration 10 mg/L), the degradation efficiency of CIP achieved 92.64% within 60 min. The corresponding reaction rate constant is 0.03814 min −1 , which is 3.57, 2.82 times than single BiOBr (0.01068 min −1 ) and Bi 12 O 17 Cl 12 -Ov (0.01354 min −1 ). Moreover, h + and O 2 − are the main active species for the degradation of CIP based on active species trapping experiment and EPR spectrum. The degradation pathways were proposed by Density Functional Theory (DFT) calculation and LC-MS analysis. Combining the T.E.S.T. soft stimulate and bean sprout growth experiment proved that the degraded solution has no obvious toxicity. More importantly, Bi 12 O 17 Cl 12 /BiOBr-1 also has a satisfied degradation efficiency for other pollutions. This work provides a feasible strategy to design oxygen vacancy-rich S-scheme heterojunction photocatalysts for wastewater treatment.

Electrode stability is a critical determinant of the long-term operational efficiency and service life of electrochemical systems. Molten salt electrolysis technology utilizing consumable anodes offers a promising green and low-carbon pathway for the preparation of refractory metals and alloys, owing to its process simplicity, environmental friendliness, and high product purity. However, during electrolysis, the coupled thermo-mechanical fields can induce localized stress concentration in the anode, posing challenges to its structural integrity. This paper takes the electrolytic extraction of metallic zirconium using ZrC x O y anode as an example to study the stability of consumable anodes. Through a combination of experimental and simulation approaches, we systematically analyze the influence of key parameters-including anode geometry, immersion depth, and electrolysis temperature-on stability. The findings aim to provide theoretical guidance for optimizing electrolysis processes and designing robust anode structures.

The widespread use of chlortetracycline (CTC) in agriculture and aquaculture has raised significant concerns regarding environmental contamination and human health risks. There is a critical demand for developing rapid, sensitive, and selective detection techniques for CTC identification. In this study, we introduced a smartphone-integrated ratiometric fluorescent sensor utilizing Al-doped carbon dots (Al-CDs), which were synthesized through a straightforward one-pot hydrothermal method. CTC quenches Al-CDs' fluorescence at 400 nm via the inner filter effect. Concurrently, a distinct fluorescence signal at 500 nm emerged, resulting from the enhanced intrinsic fluorescence of CTC upon its chelation with Al 3+ on the surface of Al-CDs. This ratiometric fluorescence spectral response enables a visible color shift from blue to green upon UV irradiation. The constructed sensor achieves a remarkable detection limit of 0.17 μM and displays exceptional specificity toward CTC among other antibiotics, metal ions and amino acids. Successful application in real water samples yielded satisfactory recovery rates (98.5–110.6%), highlighting the potential of this smartphone-integrated platform for on-site and quantitative CTC detection.

To address the low flotation separation efficiency between apatite and calcite, a novel fucose–CuSO 4 complex depressant was developed. This study elucidated the selective depression mechanism of the fucose–CuSO 4 complex on calcite. Micro-flotation results demonstrated that under optimized conditions—pH 9, CuSO 4 concentration of 3 × 10 −4 mol/L, and a molar ratio of CuSO 4 to fucose of 1:3—the recovery of apatite and calcite were 95.78 % and 14.71 %, respectively. Experimental findings revealed that when CuSO 4 is used alone, Cu 2+ preferentially adsorbs onto the apatite surface, whereas SO 4 2− selectively binds to Ca sites on the calcite surface. In the presence of both fucose and CuSO 4 , a ternary bridging structure—CO 3 2− –Cu 2+ –O (fucose)—is formed via oxygen atoms in carbonate groups on calcite surface. The adsorbed species included CuC 6 O 5 H 10 + complexes, with an adsorption layer thickness of 20–40 nm. In contrast, no characteristic ion fragments of fucose were detected on the apatite surface, the adsorption layer thickness ranged from 5 to 10 nm, with significantly lower density. DFT calculations confirmed effective orbital overlap between fucose and Cu(OH) 2 , indicating strong interaction. The adsorption energy of fucose on calcite in the presence of Cu(OH) 2 was calculated as −191.57 kJ/mol, substantially higher than that on apatite, thereby validating the selective depression mechanism. This study elucidates the depression behavior of fucose–Cu 2+ complex depressants and provides a new idea for the selective suppression of calcium-bearing gangue minerals.

High-performance fiber-based nanofluidic membranes exhibit significant potential in osmotic energy harvesting, yet conventional aramid nanofibers (ANFs) membrane is limited by insufficient ion selectivity for efficient power generation. This study proposes a simple yet ingenious proton donor-induced phase deposition strategy to construct ANFs membrane with ultrafast ion transport capabilities. By introducing negatively charged cellulose acetate (CA) as proton donor in aramid deprotonation system (KOH/DMSO), a CA-cellulose-water ternary proton-donor system spontaneously forms in this strong alkaline environment. This system markedly enhances ANFs dispersion through a mild and stepwise proton release mechanism. Even more fortunately, during the reaction, the deacetylation of CA generates insoluble cellulose, which is deposited in situ on the fibers, narrowing the fiber spacing. This endows the membrane with sub-nanometer ion transport channels, featuring an interlayer spacing of 4.59 Å and channel diameters of 2 nm. The fabricated membrane exhibits exceptional ion selectivity (cation transport number of 0.9), achieves a power density of 22.13 W/m 2 and 28.14 W/m 2 using simulated- and natural seawater-river water, outperforming most current membranes. Simultaneously, it demonstrates high mechanical strength (122 MPa tensile strength at 1 μm thickness). This research provides novel insights into the application of ANFs membranes for efficient osmotic energy conversion.
