Herein, covalent organic framework (COF) and covalent triazine framework (CTF) have been successfully combined for electrochemical sensing via carboxylated multi-walled carbon nanotubes (COOH-MWCNTs). The COF was synthesized from 1,3,5-tris-(4-formylphenyl) benzene (TFPB) and benzidine (BD), named TFPB-BD-COF. Meanwhile, CTF was synthesized by 1, 4-dicyanobenzene (DCB), then chemically activated with KOH at 700 °C to obtained chemically activated porous product, caCTF-1–700. A novel electrochemical sensor based on TFPB-BD-COF/caCTF-1–700/COOH-MWCNT composite was constructed for simultaneous detection of acetaminophen (ACOP) and 4-aminophenol (4-AP). The electrochemical behaviors of the ACOP and 4-AP on the TFPB-BD-COF/caCTF-1–700/COOH-MWCNT electrode were explored via differential pulse voltammetry (DPV) and cyclic voltammetry (CV). The fabricated TFPB-BD-COF/caCTF-1–700/COOH-MWCNT composite modified glassy carbon electrode (GCE) possessed outstanding electrocatalytic performance for the electro-oxidation of acetaminophen (ACOP) and 4- aminophenol (4-AP). Under optimal conditions, the linear ranges were 0.6–150 μM for ACOP and 4-AP, respectively, with the low detection limits of 0.053 μM and 0.075 μM, respectively. In addition, it also showed excellent selectivity, repeatability, reproducibility and stability. The proposed modified electrode was applied for the determination of ACOP and 4-AP in acetaminophen tablet and Yellow river water and obtained satisfactory recovery between 96.31~103.96% and 97.2~101.6%, respectively.

The development of symmetrical solid oxide fuel cells (SSOFCs) faces a significant challenge in designing electrode materials that exhibit both high activity and stability. In this work, a novel layered perovskite oxide symmetric electrode material PrBaFe 1.8 Hf 0.2 O 5+δ (PBFH) for SSOFCs is proposed and synthesized. Doping Hf at the B-site of PrBaFe 2 O 5+δ (PBF) improves the stability in reducing atmosphere and increases the concentration of oxygen vacancies . Furthermore, a small amount of RuO x is deposited by atomic layer deposition (ALD) onto PrBaFe 1.8 Hf 0.2 O 5+δ scaffold as symmetric electrodes. The surface modification of ALD-RuO x significantly boosts the catalytic activity for both fuel oxidation and oxygen reduction, simultaneously. Compared to PBF electrodes, the interfacial polarization resistances of RuO x -PBFH decrease to 0.77 Ω cm 2 under H 2 /Ar and 0.021 Ω cm 2 under air atmosphere at 800 °C, respectively. At 800 °C, SSOFCs equipped with RuO x -PBFH symmetric electrodes exhibit a high peak power density of 0.85 W cm −2 and 0.41 W cm −2 using humidified hydrogen and propane as fuels, respectively. Moreover, the RuO x -PBFH electrode demonstrates long-lasting performance, displaying high resistance against coking. These findings reveal a facile ALD approach for tailoring symmetric perovskite electrodes, offering robust and efficient electrocatalysis with efficient noble metal utilization.

Plastic waste has caused severe environmental problems. Some additives in plastics, like organophosphates, enter the environment with plastic waste, causing significant harm to plants and creatures. However, the primary method of recycling phosphorus-containing plastic, especially polycarbonate and acrylonitrile-butadiene-styrene copolymer (PC/ABS), is a mechanical method, which not only does not effectively separate plastics and organophosphates but also tends to cause polymer degradation during recycling. In order to overcome these problems, we proposed an efficient and sustainable approach to recycle of phosphorus-containing plastic. In this method, N, N -dimethylcyclohexylamine (DMCHA), a switchable hydrophilicity solvent (SHS), was used to react with and extract organophosphates in plastic, achieving the goal of complete separation of plastic and organophosphates. PC/ABS can be recovered by precipitation. Dissolved organophosphates can also be easily recovered due to the switching characteristics of SHS. Both of recovered materials were of high purity and were close to virgin materials. This technique is an easy and efficient approach to separate plastic and organophosphates, which has excellent application prospects in recycling phosphorus-containing plastic.

A novel magnetic molecularly imprinted electrochemical sensor (MMIP-sensor) combined with magnetic molecularly imprinted solid-phase extraction (MMISPE) was constructed for rapid and sensitive detection of tetrabromobisphenol S (TBBPS) in water samples. The magnetic molecularly imprinted polymer based on magnetic graphene/multi-walled carbon nanotubes hybrid composite (MMIP/Gr-MWCNTs) was prepared as MMISPE sorbet to separate and enrich TBBPS from complex system. Adsorption results showed that the MMIP/Gr-MWCNTs possessed excellent selective adsorption toward TBBPS with a maximum adsorption capacity of 17.83 mg g − 1 . The magnetic imprinted sensor based on the magnetic Gr-MWCNTs composite modified electrode was prepared by electropolymerization of dopamine monomer . The high sensitivity of the MMIP-sensor was attributed to the large specific surface area and excellent electrical conductivity of the magnetic Gr-MWCNTs composites. The detection limit of the MIP-sensor toward TBBPS was calculated as 2.1 × 10 − 11 mol L − 1 (S/N = 3). Under the optimum conditions, the MISPE-MMIP-sensor combination system provided 10–12 fold preconcentration than that of MMIP-sensor alone determination. The MISPE-MMIP-sensor was successfully used for detection of TBBPS in drinking water , rain water , lake water and tap water with recoveries of 88.4–98.8%.

Fluorescent carbon quantum dots are emerging as a new class of fluorescent probes due to their unique optical properties . Herein, we presented a simple, one-pot and effective preparation strategy for copper-functionalized carbon quantum dots (Cu-CDs). The Cu-CDs demonstrated excitation-independent emissions, high fluorescent quantum yield (~ 24.4%) and excellent fluorescent stability. The fluorescence of Cu-CDs could be quenched efficiently in the presence of histidine (His) due to the coordination occurring between surface Cu and imidazole side chains of His. Thus, the Cu-CDs could be used as an efficient fluorescent probe for His detection. Under optimal conditions, the fluorescent signals of Cu-CDs decreased linearly with the concentrations of His over a range of 0.1–15 µM. The detection limit was 30 nM. The proposed method provided obvious advantages of rapid response, convenience, simplicity, high selectivity and sensitivity. Moreover, good results also have been obtained for His detection in real biological fluid samples.

Fast curing hydrogels are highly valuable in the skin care industry. Multi-arm polyethylene glycol (PEG) is a commonly used crosslinking agent for the preparation of fast curing hydrogels. However, the hydrogel preparation using multi-arm PEG crosslinking agents usually requires the end group modifications of reactants, which makes the preparation process complicated and produces hydrogels with low curing rates. In the present study, a fast in situ curing hydrogel, 4-arm-PEG-succinimidyl carbonate/carboxymethyl chitosan (PEG-SC/CMCS), was prepared using 4-arm-PEG-SC as the crosslinking agent and carboxymethyl chitosan (CMCS), a derivative of natural polysaccharide with excellent comprehensive properties, as the framework without any end groups modified. The structure and properties of the prepared hydrogel were characterized by FTIR, XRD, SEM, rheology and swelling kinetics. The effects of reaction conditions on the structure and properties of hydrogel were investigated. The PEG-SC/CMCS hydrogel exhibited pH-sensitive swelling behaviors. Its application potential in skin care products is demonstrated with its excellent sustained-release performance of Vitamin C, a model drug for skin treatment, and high adsorption capacity of heavy metal ions that are easily deposited on skin surface. Our work has provided a new strategy for building multifunctional gel materials for skin care and offered a PEG-SC/CMCS hydrogel with great application potentials.

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.
