Pesticide residues on dried star anise remain major barrier to product safety and quality; current washing practices unfortunately fail to balance decontamination efficiency with retention of bioactive compounds. Suitability of emerging decontamination media, in particular alkaline electrolyzed water (ALEW), for star anise has nevertheless not been assessed. The present study therefore compared use of ALEW with use of conventional methods at ambient and high-temperature conditions to decontaminate star anise; four representative fungicides were tested. Quality of dried star anise was then determined in terms of color, rehydration behavior, shikimic acid and volatile oil contents. ALEW treatment at ambient temperature provided superior pesticide reduction (9.3–14.7%) compared with other treatments; such treatment also led to enhanced rehydration capacity and color. Unexpectedly, high-temperature soaking markedly reduced effectiveness of ALEW and caused significant losses of shikimic acid and volatile oils. Machine learning modeling identified support vector regression as most accurate tool to predict influences of pH, soaking temperature and soaking time of ALEW on pesticide residues decontamination and reveals distinct parameter sensitivities among different pesticides. Short-duration, ambient ALEW treatment offers practical and quality-preserving solution for pesticide control in star anise processing, with clear implications for sustainable spice manufacturing.

Given the confining effect of porous carbon and strong surface polarity of transition metal phosphides, their composite would be a promising cathode candidate to solve the problems of lithium–sulfur batteries including volume expansion and the shuttling effect of polysulfides. Herein, cobalt phosphide (CoP)-loaded phosphorous (P)-containing carbonized bamboo (CoP/PCBs) composites were fabricated via the co-pyrolysis of phytic acid, waste bamboo and Co(NO3)2·6H2O via Joule heating at 600–1200 °C. Hydrogen radicals released from phytic acid enabled CoP/PCBs with developed porosity (438.1–812.4 m2/g). CoP nanoparticles coated with graphitic carbon were distributed uniformly on a porous matrix of PCBs. CoP/PCBs presented obviously enhanced adsorption capabilities for Li2S6, and 57.8–80.4 wt.% of sulfur was confined in CoP/PCBs/S cathodes. CoP/PCB heated at 1200 °C exhibited a high reversible capacity of 477.5 mAh/g after 500 cycles at a current density of 1 C with an average capacity decay rate of 0.045%. The specific capacity remained at 453.3 mAh/g after 300 cycles even under a high sulfur load of 4.0 mg/cm2. Conversion of sulfur/polysulfides during the electrochemical process could be promoted via the physical confinement of sulfur and chemical confinement of Li2S6. This work provided a valuable reference for the facile fabrication of lithium–sulfur cathodes and utilization of metal phosphides in advanced lithium–sulfur battery systems.

Severe voltage polarization limits the deployment of zinc–iodine batteries by collapsing energy/power output under high iodine loadings (> 10 mg cm −2 ) and current densities (> 3 A g −1 ). Yet its origins remain unresolved because ohmic, charge-transfer, and mass-transport losses evolve concurrently during operation. Here we establish a timescale-decoupled polarization framework that quantitatively differentiates these overlapping voltage losses in operando and links them to electrode design principles. The analysis reveals that concentration-polarization dominates under practical high-loading and high-rate conditions. Guided by this insight, we design a polarization-resistant cathode host consisting of Fe single atoms anchored on porous graphene (Fe@PG). The architecture integrates a conductive graphitic framework for rapid electron transport, atomically dispersed Fe–N 4 sites for accelerated I − /I 3 − redox conversion, and hierarchical pores with strong iodine affinity for efficient mass transport and species confinement, thereby concurrently suppressing ohmic, activation, and concentration polarization. At an iodine loading of 14.1 mg cm −2 , the I 2 /Fe@PG‖Zn cell delivers a low polarization loss of 0.43 V at 70.5 mA cm −2 (5 A g −1 ), 29.5% lower than the control, together with energy/power densities of 214.1 Wh kg −1 /1761.4 W kg −1 , and 82.0% capacity retention after 3000 cycles. This work provides a generalizable strategy for decoding and regulating polarization kinetics in conversion-type Zn–halide batteries.

Owing to the inherent limitations of a single coalification degree, precursors derived from a single-rank coal often struggle to simultaneously fulfill the requirements of composition, structure, and performance. To address this, a blended-coal strategy combining oxygen-rich low-rank Baishihu coal and aromatic-rich high-rank Yicheng coal is proposed to overcome the reactivity–stability trade-off during KOH/KCl activation. The optimized sample, BYCM-40, delivers a high specific surface area of 2556.53 m2·g−1, a hierarchical porosity with 75% micropores and 25% mesopores, and 22.77 at% surface oxygen, achieving a specific capacitance of 357.8 F·g−1and remarkable cycling stability with 99.2% retention after 20,000 cycles. This work is expected to open a sustainable pathway for valorizing low-rank coals into high-performance porous carbons for advanced supercapacitors.

The deployment of aqueous zinc metal batteries (AZMBs) is still hindered by unstable interfacial kinetics of Zn metal anodes, resulting in uncontrolled dendrite growth and parasitic side reactions at the Zn/electrolyte interface. Herein, we develop an in situ strategy to construct fluorine-functionalized nanoarrays on a Zn anode with preferential Zn (002) texture exposure (F-Zn) to address these issues. The results demonstrate that the multifunctional Zn anode integrates several key advantages: fluorine functionalization imparts zincophilic characteristics that homogenize Zn 2+ nucleation and stable interfacial kinetics, The nanoarray interface facilitates electrolyte wettability and accelerates interfacial Zn 2+ flux; meanwhile, the dominant Zn (002) crystallographic texture induces uniform Zn deposition and enhances corrosion resistance. As expected, the F-Zn anode exhibits a low nucleation overpotential and enables symmetric cells to operate stably for over 3100 h at 1 mA cm –2 @1 mAh cm –2 and over 1000 h at 4 mA cm –2 @1 mAh cm –2 . Moreover, when coupled with an activated carbon (AC) cathode, the F-Zn||AC delivers exceptional rate capability and maintains approximately 99.2% capacity retention after 10,000 cycles at 4.0 A g –1 . This work presents an effective strategy integrating crystallographic engineering with surface functionalization for high-performance Zn anodes toward advanced AZMBs.

Heteroatom-doped hierarchical porous carbons are suitable electrode materials for supercapacitors. Mesopores and macropores can accelerate ion diffusion by shortening transport distance. However, the precise control of mesoporous and macroporous structures faces considerable challenges, and the optimal structure for efficient ion transport remains unclear. Herein, a self-assembly-synergistic activation coupling strategy is developed to prepare nitrogen/oxygen co-doped hierarchical porous carbons (HPCs) with tunable meso -macroporous structures from lignosulfonate sodium (LS). Ca 2+ coordinates with LS and subsequently bonds with C 2 O 4 2- , followed by the crystallization of NaNO 3 , forming LS/CaC 2 O 4 /NaNO 3 precursor. During precursor pyrolysis, LS decomposes to release CO 2 , promoting the reaction of CaC 2 O 4 and Na 2 CO 3 into Na 2 Ca(CO 3 ) 2 . NaNO 3 and Na 2 Ca(CO 3 ) 2 respectively act as activator and template, constructing hierarchical porous structures with meso -macropores. The HPCs prepared at 600 °C (HPC-600) exhibit the highest capacitances toward the adsorption of K + (368.9F g −1 at 0.5 A g −1 ) and Zn 2+ (333.8F g −1 at 0.1 A g −1 ), due to the highest 0.68 nm micropore volume and highest edge nitrogen/C O content (10.8 at.%). Meso-macroporous structure exhibits weaker K + transport capability than mesoporous structure, while can rapidly transport Zn 2+ . HPC-600 with the highest meso -macropore volume (0.872 cm 3 g −1 ) delivers inferior and excellent rate capabilities for K + and Zn 2+ adsorption, respectively. The zinc ion hybrid capacitors with HPC-600 cathode achieve high energy densities of 118.7 and 33.4 Wh kg −1 at 80 and 40000 W kg −1 , along with remarkable cycling stability (96.7% capacitance retention after 19,800 cycles).

Aqueous zinc-ion capacitors are currently drawing attention for advanced energy storage applications, primarily because of their exceptional safety performance, environmental sustainability, and overall economic value. Hydrogel electrolytes are promising candidates for the construction of zinc-ion hybrid supercapacitors. However, most of the previously reported hydrogel electrolytes suffer from insufficient mechanical strength and limited fatigue resistance. In this study, Cu 2+ modification was introduced into a dual-physically and chemically crosslinked car-boxymethyl cellulose/chitosan (CC) gel polymer electrolyte to yield a Cu 2+ -CC gel. Coordination between Cu 2+ and functional groups (— OH, —COO − , and —NH 2 ) substantially improved the mechanical properties of the electrolyte, demonstrating a maximum tensile stress of (7.20±0.52) MPa. The resulting Cu 2+ -CC gel possesses a porous architecture, along with high ionic conductivity (31.25±0.76 mS·cm −1 at ambient temperature), a wide electrochemical stability window (2.54 V), and a high exchange current density (1.38 mA·cm −2 ). The zinc-ion hybrid supercapacitor assembled with this electrolyte retained 95.2% over 38000 charge-discharge cycles at 1 A·g −1 . Furthermore, the assembled device demonstrated remarkable operational stability even under severe mechanical deformation, including bending from 0° to 180°.

Commercial AC is employed as the support to fabricate the P-CoO/Co 9 S 8 @AC electrode. • The formation of P-CoO/Co 9 S 8 @AC realizes the deep coupling of macroscopic structural buffering and atomic-scale electronic regulation. • The synergy of heterointerface and P doping enhances OH − adsorption and accelerates redox reaction rate. • The ASC achieves a high energy density of 90.4 Wh kg −1 at 750 W kg −1 . Supercapacitor performance is largely determined by electrode materials. Transition metal compounds (TMCs) have high theoretical capacities but suffer from sluggish charge transport and volume-induced structural degradation, which limits their practical applications in energy storage. To overcome the inherent bottlenecks of TMCs in energy storage, this work reports a novel dual-regulation strategy to construct a P-doped CoO/Co 9 S 8 heterostructure anchored on activated carbon (P-CoO/Co 9 S 8 @AC). The formation of the P-doped CoO/Co 9 S 8 @AC heterostructure enables close coupling between macroscopic structural buffering and atomic-scale electronic modulation. Introducing activated carbon (AC) suppresses particle agglomeration and buffers volume expansion, while the synergistic effect of heterointerface engineering and P doping significantly reduces the charge-transfer resistance to 0.27 Ω. Benefiting from these multidimensional advantages, the as-prepared material delivers a specific capacity of 1697.3 C g −1 (3394.6 F g −1 ) at 1 A g −1 , outperforming previously reported nickel sulfide/nickel oxide heterostructures (2278 F g −1 ) and P-doped ternary cobalt-based sulfide electrodes (2716 F g −1 ). Density functional theory (DFT) calculations show that the P-doped heterostructure has an OH − adsorption energy of −4.82 eV and an upshifted d-band center, thereby improving intrinsic conductivity and OH − interfacial adsorption. Furthermore, the assembled hybrid supercapacitor (HSC) achieves a high energy density of 90.4 Wh kg −1 at a power density of 750 W kg −1 , while retaining 86.1% of its capacity after 20,000 cycles. This study provides a design strategy for constructing high-performance composite electrodes by integrating heterointerface engineering and heteroatom doping. A novel strategy is reported to construct P-CoO/Co 9 S 8 @AC. DFT calculations demonstrate that the synergistic effect of CoO/Co 9 S 8 heterostructure formation and P doping strengthens OH − adsorption and boosts the electrochemical performance.

Tailored pore network FPCE was designed as the electrolyte for FCS. • Cement-PA-KOH-AM20 integrates good electrochemical performance with outstanding mechanical flexibility. • Operates reliably at −10-65 °C, resists damage, provides 7 °C insulation, and retains performance after 6 months outdoors. • Powers LEDs, phones, displays, and fans even under bending or twisting. Cement-based supercapacitors are emerging as key enablers of the green transition, unifying the widespread infrastructural presence of cement with the ability to store electrical energy. However, their inherent rigidity has hindered integration into irregular, free-form architectural surfaces. Here, we report the first flexible cement-based supercapacitor, which combines high electrochemical performance with exceptional mechanical adaptability. The device employs a cement-composite electrolyte engineered with a tailored network of mesopores and capillary pores, achieving an ionic conductivity of 35.28 mS cm −1 alongside a low Young's modulus of 81.6 MPa. In an asymmetric electrode configuration, the supercapacitor delivers an areal capacitance of 215.3 mF cm −2 , an energy density of 76.55 μWh cm −2 , and a power density of 726.95 μW cm −2 , with 83.3% capacitance retention over 2000 cycles. It operates reliably from −10 to 65 °C, withstands mechanical damage without failure, provides a 7 °C thermal insulation benefit, and shows negligible performance loss after six months outdoors. Capable of efficient solar energy storage, it can power small electronic devices such as LEDs, a mobile phone, and fans even when bent or twisted. This work demonstrates a versatile, deformable energy-storing cement, paving the way for multi-function building materials in next-generation free-form architecture.

A semi-immobilized CL coating is designed for stable Zn anodes. • Hydrophobic framework isolates water and repels SO 4 2− via sulfonate. • Ca 2+ tip-shielding and lignosulfonate anions guide uniform Zn deposition. • Symmetric cell cycles 4500 h; full cell retains 93.99% after 1500 cycles. Aqueous zinc-ion batteries (AZIBs) are attractive candidates for large-scale energy storage, yet the zinc anode is plagued by parasitic reactions and dendrite growth. Herein, we propose a semi-immobilized ion-regulation concept by engineering a hydrophobic composite coating on zinc foil (denoted as CL@Zn coating) to form the CL@Zn electrode. The coating consists of calcium lignosulfonate (CL), conductive carbon black, and PVDF. Unlike conventional fully solid coatings or fully dissolved additives, this design enables a small fraction of CL to controllably dissolve, releasing functional lignosulfonate anions and Ca 2+ ions, while the majority remains anchored within the three-dimensional (3D) framework. This creates a dynamic, synergistic protection system: the coating physically repels water and SO 4 2− ; the dissolved anions regulate Zn 2+ transport and favor (101)-oriented Zn growth, while released Ca 2+ ions contribute to a “tip-shielding effect” against dendrites. Moreover, a compact yet microporous Zn 4 SO 4 (OH) 6 ·xH 2 O (ZHS)-derived interfacial layer forms in situ at the coating/electrolyte interface, acting as a beneficial SEI-like interphase that facilitates interfacial ion transport and further stabilizes Zn deposition. Consequently, the CL@Zn symmetric cell cycles for nearly 4500 h at 0.5 mA cm −2 , and the CL@Zn//MnO 2 /CNT full cell exhibits a capacity retention of 93.99% after 1500 cycles at 1 A g −1 . This work presents a versatile, biomass-derived dynamic interface strategy for durable metal anodes. A semi-immobilized calcium lignosulfonate coating creates a hydrophobic, ion-regulating interface that suppresses dendrites and side reactions, enabling ultra-stable zinc anodes for aqueous zinc-ion batteries.

Ship icing poses significant safety and operational risks. Although superhydrophobic coatings (SHCs) offer a promising passive anti-icing strategy, their practical application is limited by factors such as poor durability, the environmental constraints of single-function de-icing methods, and ecological issues associated with fluorinated materials. To address these challenges, this study has designed a novel fluorine-free multifunctional superhydrophobic coating that integrates photothermal effects and self-healing capabilities. The coating uses γ-aminopropyltriethoxysilane (KH-550) as the key modifier for the fluorine-free modification of epoxy resin; the surface layer achieves self-healing superhydrophobic functionality through the thermal mobility of beeswax, while the bottom layer consists of acetylene black and nanoscale graphite powder to form a conductive network. Leveraging its photothermal and electrothermal effects, the coating can melt accumulated ice via rapid photothermal heating (reaching approximately 90 °C within 300 s). Additionally, through heat-induced conduction of beeswax, the coating can autonomously restore its superhydrophobicity after mechanical or chemical damage and maintain performance over multiple cycles. The resulting coating exhibits strong adhesion to the substrate. After immersion in a 3.5 wt.% NaCl solution for 14 days, its corrosion current density is only 2.56 × 10 –10 A/cm 2 , representing a 99.47% improvement compared to silicon-modified epoxy resin (Si-EP). Furthermore, even under prolonged sand particle erosion, the coating retains long-lasting superhydrophobicity. This study provides a promising and scalable strategy for advanced anti-icing applications in marine environments by synergistically combining environmental friendliness, photothermal de-icing, self-healing durability, and enhanced corrosion resistance in a fluorine-free system.

Polyethylene oxide (PEO)-based polymer electrolytes hold promise for application in solid-state lithium metal batteries. However, the high crystallinity of PEO poses a significant challenge to ion transport, particularly limiting its room-temperature performance. Poly(vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP), a semi-crystalline polymer with rigid fluorocarbon chains, can provide robust mechanical support to the electrolyte system. Herein, a quasi-solid electrolyte (QSE) was fabricated by using PEO and PVDF-HFP, in which succinonitrile (SN) was introduced as a plasticizer to enhance the electrochemical properties at room temperature. Innovatively, 1,1,2,2-tetrafluoroethyl-2,2,3,3-tetrafluoropropyl ether (TTE) was employed as a shield layer to prevent direct contact between the Li anode and the prepared SN-modified PEO/PVDF-HFP-QSE, thus forming a stable anode/electrolyte interface. The obtained TTE-P 8 P 2 S(12%)-QSE exhibits high room-temperature electrochemical properties, with an ionic conductivity of 4.02 × 10 –4 S cm –1 , a lithium-ion transport number of 0.47, and a wide electrochemical window of 5.4 V vs. Li + /Li. By interfacial modification, TTE-P 8 P 2 S(12%)-QSE can enable long-term cycling of LiCoO 2 cathodes and Li anodes, with an initial discharge capacity of 126.9 mAh g –1 , and achieve an average capacity of 142.8 mAh g –1 within 100 cycles at room temperature. Characterizations reveal that the incorporation of TTE preserves the structural integrity of the lithium electrodes, promotes efficient utilization of active lithium ions, and tailors the composition and structure of the solid-electrolyte interphase (SEI) on the lithium metal anode, thereby substantially enhancing interfacial stability. This work provides a feasible strategy for building high-energy-density lithium metal batteries for room-temperature applications.
