Aqueous zinc-ion batteries (AZIBs) hold great promise for stationary energy storage, yet their practical deployment is critically impeded by the uncontrolled dendritic growth and parasitic side reactions. Here, we report an interfacial dual-coordination strategy to induce Zn deposition along the Zn(002) facet and suppress the parasitic side reactions. By employing lactic acid (Lac) to pretreat commercial Zn foil, we construct a chemisorbed interface that serves a synergistic “inhibition-guidance” function: the carboxyl group (-COO − ) forms strong bidentate coordination to passivate high-energy Zn (100)/(101) facets, while the hydroxyl group (-OH) establishes a low-energy diffusion pathway on the Zn (002) facet to guide Zn 2+ migration. This intrinsic regulation induces a highly selective Zn (002)-preferred growth, resulting in a dendrite-free lac@Zn anode. Consequently, the lac@Zn symmetric cell achieves a long lifespan of 4900 h (1 mA cm −2 , 1 mAh cm −2 ) and 500 h (5 mA cm −2 , 5 mAh cm −2 , DOD = 37%). Besides, the lac@Zn//MnO 2 full cell delivers exceptional reversibility with 76% capacity retention after 3000 cycles, and a pouch cell presents a high discharge capacity of 0.2 Ah. This work offers a new perspective for developing ultradurable and scalable Zn anodes through precise interfacial engineering.

Arsenic-alkali leaching residue (AAR), generated during antimony smelting, is a hazardous solid waste containing arsenic and antimony. Its safe disposal and resource-oriented utilization are constrained by the strong stabilization of As- and Sb-bearing species in a high-alkali matrix. Herein, we investigated the alkali locking effect during carbothermal roasting of AAR and proposed a SiO2-assisted roasting strategy to promote the simultaneous volatilization of arsenic and antimony. Thermodynamic calculations indicate that, in a sodium-rich roasting system, representative As- and Sb-bearing species preferentially transform into thermodynamically stable Na3AsO4and Na3SbO4, thereby suppressing their reductive conversion into volatile As2O3and Sb2O3. Direct roasting experiments confirmed that simply increasing roasting temperature, carbon dosage, or roasting time was insufficient to achieve efficient simultaneous volatilization of As and Sb, which experimentally supports the existence of the alkali-locking effect. The introduction of SiO2weakened sodium-induced immobilization by favoring the formation of sodium silicate phases, thereby enhancing the thermodynamic driving force for the generation and release of As2O3and Sb2O3. Under the conditions of 900 °C, 90 min, 30% carbon dosage, and 10% SiO2addition, the volatilization rates of arsenic and antimony reached 93.25% and 93.80%, respectively. XRD and SEM-EDS revealed that the addition of SiO2promoted the reconstruction of Na–Al–Si-bearing phases and the development of porous slag structures, thereby facilitating the mass transfer and volatilization of As/Sb species. Preliminary co-roasting experiments with flotation antimony concentrate suggest the feasibility of using Si-bearing gangue as an in situ additive for AAR treatment. This study provides a thermodynamic and experimental basis for the resource-oriented detoxification of arsenic-alkali leaching residue.

Pressure-sensitive sensors that can respond to tiny signals are key to various medical and healthcare monitoring applications. Developing wearable sensors that combine high sensitivity in real time, flexibility, and biological and environmental safety is challenging. In this paper, a biomass-based conductive silicone elastomer is designed via ultraviolet curing. The deep eutectic solvents are well dispersed within the silicone matrix via hydrogen bonding to ɑ-lipoic acid moieties within the network. Along with the bottlebrush topology of the network, the engineered material exhibits ultra-softness (Young's modulus 159 kPa), excellent rebound, and fatigue resistance under repeated high strains. Meanwhile, the engineered sensor shows outstanding electrical sensitivity to deformation in the range of 0–20 kPa. These features enable precise, real-time monitoring of subtle signals, including respiration, abdominal and chest movements, wrist pulse, and facial expressions. The green conductive silicone elastomer shows great potential in the development of portable Polysomnography and other high-end wearable devices in the future.

The ability of sodium metal batteries (SMBs) to operate under low temperatures is highly desirable; however, achieving stable performance remains challenging due to limitations in cation−solvent interactions and sluggish desolvation kinetics. Salt precipitation or electrolyte solidification severely impedes ion transport, leading to low Coulombic efficiency for Na plating/stripping, rampant dendrite growth, fragile solid electrolyte interphase (SEI) formation, and severe capacity decay. Localized high-concentration electrolytes (LHCEs) offer a promising solution but often rely on costly and volatile fluorinated ether diluents. Herein, we introduce cyclopentyl methyl ether (CPME) as a cost-effective diluent to formulate a NaPF 6 −diethylene glycol dimethyl ether (G2)/CPME LHCE. Combining theoretical and experimental analyses, we demonstrate that the bulky cyclopentyl group in CPME introduces steric hindrance, which kinetically excludes CPME from the primary Na + solvation sheath while weakening Na + −G2 coordination. This facilitates PF 6 − entry into the inner solvation sheath, forming an anion-enriched structure that promotes a gradient NaF-rich SEI. As a result, Na‖Na symmetric cells operate stably for over 3600 h at 25 ° C, and Na‖Na 3 V 2 (PO 4 ) 3 full cells retain 90.1% of their initial capacity after 1000 cycles at 1 C. At −30 ° C, they deliver 90.9% capacity retention after 500 cycles at 1 C, compared to 72.7% for the NaPF 6 −G2 electrolyte. This work establishes CPME as a cost-effective diluent for enabling low-temperature-tolerant SMBs.

The initial oxidation stage of high-entropy carbides (HECs) is a decisive yet poorly understood “black box” that governs their ultimate performance for ultra-high-temperature applications. Here, we unveil a powerful strategy—predesigning carbon vacancies—to fundamentally enhance HECs oxidation resistance. By integrating in situ x-ray diffraction (XRD) and in situ transmission electron microscopy coupled with electron energy loss spectroscopy (TEM-EELS), we provide the first direct, atomic-scale visualization of oxygen atoms preferentially occupying these predesigned vacancies during the incipient oxidation stage, leading to the dynamic formation of a metastable metal–carbon–oxygen (M–C–O) interfacial layer. Our combined experimental and theoretical analyses reveal a dual enhancement mechanism: kinetically, M–C–O suppresses both oxygen adsorption on the (111) surface and its subsequent inward diffusion; thermodynamically, they stabilize the HEC lattice at elevated temperatures, thereby increasing the energy barrier for M─C bond cleavage. This work not only deciphers the atomistic origin of enhanced oxidation resistance but also establishes a simple, general, and efficient design principle for next-generation ultra-high-temperature ceramics.

Lightweight broadband microwave absorbers with strong attenuation remain challenging because efficient absorption requires balanced impedance matching and electromagnetic loss over a wide frequency range. Herein, hierarchical core–shell BCN@CoNi@PANI (BCNPa) composites were rationally designed by integrating BCN, CoNi alloy, and conductive PANI. BCN serves as a lightweight dielectric substrate, CoNi provides magnetic loss, and the outer PANI shell regulates dielectric response and conductive loss. The electromagnetic properties of BCNPa can be effectively tuned by adjusting the PANI content. The excellent absorption performance over 2–18 GHz originates from the synergistic effects of impedance matching, dielectric loss, magnetic loss, and hierarchical structural attenuation. Dielectric loss is mainly related to defect-induced dipole polarization, interface-related polarization relaxation, and conductive loss from the π-conjugated PANI shell, while magnetic loss arises from natural resonance, exchange resonance, and eddy current loss of CoNi. Benefiting from optimized dielectric–magnetic balance, BCNPa-2 achieves ultralow minimum reflection loss ( RL min ) of − 81.4 dB at 14.12 GHz and an ultrabroad effective absorption bandwidth ( EAB ) covering nearly the entire measured range. This work provides an effective strategy for high-performance broadband microwave absorbers.

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.
