F-CN@RGO presents multi-dimensional synergy between the conductive framework and heteroatom doping. • F-doping induces lattice distortion, optimizes the electronic structure, enhances redox kinetics. • It exhibits outstanding long-cycle stability, with a capacitance retention of 86.8% after 30,000 cycles. • The asymmetric supercapacitor achieves a high energy density of 87.75 Wh·kg −1 and excellent cycling stability. Supercapacitors possess exceptional capacity to transfer energy quickly, but increasing cycle stability and energy density is still a major problem that hinders their commercial applications. This study uses a one-step hydrothermal method to build and construct a fluorine F-doped three-dimensional (3D) Co 2 NiO 4 @reduced graphene oxide (RGO) heterostructure (referred as F-CN@RGO) on the nickel foam (NF) electrical collector. RGO-wrapped NF functions as 3D conductive framework that suppresses the volume strain during long-term cycling while simultaneously improving the electron transfer efficiency, electrical conductivity, and specific surface area. F-doping regulates the electronic structure, surface properties, and chemical stability of Co 2 NiO 4 @RGO. The high electronegativity of F ions accelerates the electron transfer, induces the lattice distortion of Co 2 NiO 4 @RGO, and consequently modulates its electronic structure and interfacial reaction kinetics. Electrochemical tests show that the activated F-CN@RGO (A-F-CN@RGO) has a high specific capacitance of 8.76 F·cm −2 (5 mA·cm −2 ). After 30,000 cycles, the asymmetric supercapacitor with A-F-CN@RGO and activated carbon as the electrodes retains 88.2% of its initial capacitance. By generating multi-dimensional synergistic effects with rational design structure between the substrate and active materials as well as heteroatoms and host materials, this work offers a universal technique for the controlled production of high-performance electrodes for supercapacitors.

Pitch serves as an economical substance characterized by a high carbon output, rendering it appropriate for employment as negative electrode components in Na-ion batteries, thereby facilitating enhanced value-added utilization. However, through direct thermal decomposition of pitch, the resulting carbon materials characterized by high graphitization, reduced interlayer spacing, and challenges in sodium ion deintercalation, ultimately leading to limited electrochemical performance. To expand the carbon interlayer spacing, this study adopted the phosphorus doping strategy, using NaH 2 PO 2 as the phosphorus source, which interacts with the aromatic molecules in pitch to form P-C bonds. The introduction of P-C bonds effectively suppressed graphite microcrystal development during high-temperature carbonization, resulting in decreased graphitization levels and expanded interlayer distances in the carbon matrix. Besides, P-C bonds demonstrate dual functionality by improving sodium ion adsorption while simultaneously reacting with alkali metal Na + to form Na x PC y , which directly participated in sodium storage. Consequently, the soft carbon material that has been doped with phosphorus showcases enhances sodium storage capabilities when compared to traditional soft carbon material obtained through direct pyrolysis, achieving a discharge capacity of 138.56 mAh g −1 when tested over 3500 cycles at 1 A g −1 . Therefore, this research demonstrates a simple and effective method for utilizing pitch in the sodium-ion batteries.

The development of efficient catalytic systems for the low-temperature oxidation of biomass-derived sugars to value-added acids remains a key challenge in sustainable biorefining. In this study, a palladium catalyst supported on amine-functionalized biochar (Pd/BC-NH 2 ) derived from corn straw for the oxidation of corn straw hydrolysate. The catalyst achieved an exceptional total sugar acid yield of 88.2% under mild conditions at 323 K with NaHCO 3 weak base. Comprehensive characterization confirmed successful amine functionalization and Pd immobilization. Kinetic and thermodynamic analyses determined an activation energy of 41.88 kJ·mol −1 and revealed endothermic, non-spontaneous reaction characteristics. DFT calculations elucidated the mechanism, identifying hydroxide ion-assisted aldehyde C − H cleavage as the rate-determining step with an energy barrier of 56.92 kJ·mol −1 . The superior performance is attributed to a synergistic mechanism where NH 2 groups enrich surface OH − concentration and electronically modulate Pd sites. The catalyst maintained excellent stability over 10 cycles. This study provides a sustainable “waste-to-wealth” strategy for biomass valorization using a straw-derived catalytic system, supported by comprehensive mechanistic insights.

This study evaluated the dose-dependent effects of immature areca seed (IAS) powder, a major byproduct of areca nut processing, as a functional feed additive for grass carp ( Ctenopharyngodon idella ). In a 56-day feeding trial, dietary supplementation with low-dose IAS (0.5 g/kg) significantly improved growth performance, increasing the weight gain rate by 40.1% and reducing the feed conversion ratio by 19.2% compared to the control. Medium-dose IAS (1.0 g/kg) uniquely enriched the probiotic Cetobacterium in the hindgut, which was associated with improved gut health. In contrast, high-dose IAS (2.0 g/kg) induced a distinct shift in the gut microbiota, marked by the enrichment of Methylocystis and other taxa. Furthermore, IAS supplementation enhanced muscle quality by increasing essential amino acids, beneficial polyunsaturated fatty acids (EPA and DHA), and improving texture profiles (hardness and chewiness). The results demonstrate that IAS can be effectively valorized as a multifunctional feed ingredient, with its effects being highly dose-specific. This work provides a scientific basis for the potential integration of this agricultural byproduct into aquatic feed formulations.

en This link goes to a English section zh This link goes to a Chinese section The growing concern over human health issues, driven by increasingly severe electromagnetic pollution from 5G communication, has made the urgent development of high-performance electromagnetic wave (EMW) absorbing materials. Although carbide-based materials are promising because of their conductive and polarization losses, existing single-component materials fall short of future requirements. We report a lattice distortion engineering strategy to design and synthesize a stable high-entropy carbide (Ta 0.2 Nb 0.2 Ti 0.2 Zr 0.2 Cr 0.2 )C. The lowest reflection loss reaches −62.40 dB, and it exhibits an effective absorption bandwidth (EAB) of 6.39 GHz, a fourfold enhancement compared to that of the single component material TaC. Results indicate that severe lattice distortion in the high-entropy composition induces the formation of high-density defects, and the presence of metal vacancies significantly enhances the high-entropy carbides conduction loss and dipole polarization. Concurrently, the abundant grain boundaries and hyper-dense distorted lattices provide significant interfacial polarization and relaxation polarization, effectively broadening the electromagnetic absorption bandwidth. Electron holography analysis confirmed that a substantial accumulation of positive and negative charges at nano-interfaces leads to an anomalous dielectric polarization loss. This study contributes an effective pathway for designing potent single-phase electromagnetic wave absorption materials and provides a paradigm for improving other properties of high-entropy carbides via the lattice distortion strategy. 摘要 en This link goes to a English section zh This link goes to a Chinese section 随着5G通信引发的电磁污染日益严重,人们对健康问题的关注日益增加,这促使高性能电磁波吸收材料的开发成为当务之急。虽然碳化物基材料因其导电性和极化损耗而具有潜力,但现有的单组分材料仍无法满足未来需求。我们提出了一种晶格畸变工程策略,用于设计并合成稳定的高熵碳化物(Ta 0.2 Nb 0.2 Ti 0.2 Zr 0.2 Cr 0.2 )C。其有效吸收带宽(EAB)达到6.39 GHz,较单组分材料TaC提升了四倍,并且反射损耗最低可达−62.40 dB。结果表明,高熵成分中的严重晶格畸变会诱导形成高密度缺陷,而金属空位的存在显著增强了高熵碳化物的导电损耗和偶极极化。同时,丰富的晶界和超致密畸变晶格提供了显著的界面极化和弛豫极化效应,有效拓宽了电磁吸收带宽。电子全息分析证实,纳米界面处正负电荷的大量聚集导致了异常的介电极化损耗。本研究为设计高效单相电磁波吸收材料提供了有效途径,并通过晶格畸变策略为提升高熵碳化物的其它性能提供了范式。

Aqueous Zn//V2O5 batteries (ZVBs) hold promise for large-scale energy storage due to their high safety and low cost, but face critical challenges of Zn dendrite growth and parasitic side reactions at the Zn anode, coupled with severe vanadium dissolution and shuttle at the V2O5 cathode. Conventional strategies, such as electrolyte engineering or separator modifications, often focus on single-component optimization, neglecting synergistic anode and cathode regulation. Herein, we developed a Zeolite Socony Mobil-5 (ZSM-5) filled glass fiber separator (ZSM-5@GF) to address these issues simultaneously. The ZSM-5 zeolite facilitates the Zn2+ desolvation via binding H2O molecules, suppressing HER and side reactions. And it could also homogenize the ion concentration distribution for dendrite-free Zn plating/stripping. Concurrently, ZSM-5 zeolite could also immobilize dissolved vanadium species via electrostatic adsorption, mitigating cathode degradation and shuttle-induced capacity fading. Benefiting from the synergistic anode/cathode interface regulation, both electrodes dramatically extended their cycle life, and an Ah-level pouch-type Zn//V2O5 cell is also realized for continuous cycling. This bifunctional separator realizes synergistic stabilization of the Zn anode and V2O5 cathode, offering a cost-effective and scalable strategy for high-performance AZVBs toward practical applications.

A bioinspired photothermic MOF-spindle-knot microfiber (BPMM) is designed by using polyisopropylacrylamide, α-polyvinylidene fluoride as-grown metal–organic framework (MOF-303), and carbon black. A mechanism of water harvesting is related to the integrative effects of chemical and structural, i.e., BPMM composed of periodic-distributed MOF-spindle-knot with rough curvature gradient features, displaying the three-dimensional skeleton with porous channel and high-hydrophilic sites and photothermal responsive hydrophilic–hydrophobic switches as well, which runs a synergistic effect to achieve an ultrahigh water uptake-release and propel water-molecule capture in high efficiency under atmospheric low humidity. BPMM takes on ∼ 100% of water release under 1 sun for as-uptaked water and, accordingly, achieves the water harvesting capability of ∼0.16–0.62 g g–1 h–1 at ∼25 °C and ∼10–60% relative humidity (RH), which outperforms 2–8 times higher than that of normal MOF-303 or other fibers. BPMM maintains 72 cycles day–1, achieving water harvesting capability of ∼12.27 g g–1 in ∼10% RH, under 1 sun. As outdoor at ∼33.4 °C with ∼42.7% RH and ∼0.66 kW m–2, BPMM reaches water harvesting capability of ∼24.71 g g–1 day–1. This finding provides an insight into the design of supermaterials, which would be extended into some realms, e.g., water engineering, energy system, sensor devices in situations with water scarcity, etc.

Freshwater scarcity is a global challenge, and solar-driven interfacial evaporation (SDIE) technology has received widespread interest for its sustainability. However, vapor accumulation and salt deposition significantly reduce its performance. This study describes a solar evaporator with a Janus wettability grooved structure. This design not only allows for efficient double-sided evaporation but also provides a localized heat environment that greatly improves natural convection, effectively enhancing vapor diffusion. Under 1 sun irradiation, the optimized evaporator (JGE-60°) had an evaporation rate of 2.27 kg m–2 h–1. Under forced convection (4 m/s) conditions, its surface temperature dropped below ambient, reversing heat loss and increasing the evaporation rate to 5.96 kg m–2 h–1. Owing to the asymmetric wettability of its dual-sided structure, salt is selectively directed and deposited on the shaded side. This enables stable operation for 30 h in a 20 wt % brine while achieving a salt collection rate of 193.9 g m–2 h–1. This work simultaneously addresses two critical bottlenecks─vapor diffusion suppression and salt accumulation─through a simplified structural design, providing an important scientific and applied paradigm for evaporator design.

UHTCs are expected to be widely used in the aerospace industry due to their excellent ablation resistance. Currently, the low-temperature densification technology for 3D carbon fibre reinforced UHTCs is relatively scarce, meanwhile the long-term and high-temperature ablation-resistant materials still require further development. Herein, combining with reactive hot pressing at 1800 ℃, the highly dense 3D C f /ZrC-SiC composites were innovatively prepared through cyclic infiltration of slurry into 3D carbon fibre preform. The 3D C f /ZrC-SiC exhibited an excellent ablation resistance under a heat flux of 8.9 MW/m². By regulating the ratio of in situ phases ZrC and SiC, 3D C f /ZrC-SiC had an optimal mass ablation rate of only 0.75 mg/s and an optimal linear ablation rate of only -0.20 μm/s during the ablation process. The excellent ablation resistance was attributed to the formation of a dense ablation layer, which effectively inhibited the matrix from further ablation.

Transition metal selenides (TMSes), such as bimetallic selenides, are potential anodes for sodium-ion batteries (SIBs) because of their satisfied redox performances. Nevertheless, the sluggish electrochemical reaction rate and large volume expansion hinder their widespread application. To solve these disadvantages, constructing heterostructure and hollow structure are considered effective strategies. In this work, a polyhedron-templated approach is developed to synthesize uniform Cu 2 O polyhedrons, which are subsequently converted into nitrogen-doped carbon coated CuFeSe 2 /Cu 2 Se (Cu-Fe-Se@NC) via solvent thermal and annealing method. The constructed abundant heterointerfaces accelerate Na + adsorption, while the unique hollow core-shell structure effectively relieves volume expansion. Furthermore, density functional theory (DFT) calculation results indicated that the Na adsorption energies of Cu-Fe-Se@NC were higher than those of CuFeSe 2 @NC and Cu 2 Se@NC. As a result, the Cu-Fe-Se@NC anode exhibited remarkable rate performance (303 mAh g −1 , 10 A g −1 ) and superior cycling stability. This work offers a practical pathway for designing high-performance TMSes anodes through strategic heterostructure and morphology control.

Replacing the oxygen evolution reaction with more thermodynamically favourable organic oxidation reactions (OORs) can enable energy-efficient hydrogen evolution and hydrogenation. However, cathodic reduction rates are limited by sluggish OORs. Herein, we report a decoupled electrolysis strategy using a solid redox reservoir (RR) to realize an optimized hydrogen evolution reaction (HER) paired with valuable chemical synthesis. The decoupled system with a rechargeable capability features a HER coupled with RR oxidation for electricity storage, which is followed by the conversion of OORs (e.g., ethylene glycol, glycerol) into value-added chemicals coupled with the reduction of the oxidized RR to generate electricity. The fast kinetics of RR oxidation and membrane-free cell operation optimize the HER rate. The value-added chemicals and electricity are cocreated during the discharge process, offering more economic benefits. This decoupling design is universally applicable to other OORs-paired reduction systems (e.g., acetylene-to-ethylene semihydrogenation) to synthesize various chemicals for electricity storage and generation, paving a sustainable avenue for H 2 production/hydrogenation and chemicals manufacturing.

Capsaicin, the primary bioactive compound responsible for the pungency in chilli peppers, poses potential health risks at excessive levels. This study introduced a novel approach for capsaicin detection in food products using a reduced graphene oxide and multi-walled carbon nanotubes (rGO/MWCNTs)-based conductive ink integrated electrodes (IDE) produced via inkjet printing. A hybrid ink was synthesized by dispersing rGO and MWCNTs in polyethylene glycol 400, with the mass ratio of 1:2 to facilitate electron transfer. The rGO/MWCNTs-printed IDE sensor provided a dynamic range of 0.1 μM to 100 μM and a detection limit as low as 0.035 μM. The sensor exhibited good repeatability and selectivity, and maintained 97.5% of its initial response over 28 days. Practical applicability was validated in red, green, millet chilli pepper extracts and hotpot seasoning, yielding recoveries of 92.71–108.48%. The printed rGO/MWCNTs IDE platform enables sensitive capsaicin analysis and is suitable for food quality control
