Aqueous copper-selenium (Cu-Se) battery based on conversion mechanism have garnered interest due to their intrinsic safety features and high specific capacity. However, the slow conversion kinetics presents a challenge for its development. Herein, catalytic host material of NbSe 2 @few-layered Nb 2 C (NbSe 2 @f-Nb 2 C) heterostructure with built-in electric field (BIEF) is prepared by in situ selenization strategy for aqueous Cu-Se battery. Benefiting from the high electrical conductivity of f-Nb 2 C MXene, the high electrocatalytic performance of NbSe 2 and the spontaneous BIEF between NbSe 2 and f-Nb 2 C MXene, the Se redox reactions kinetics is enhanced and the reaction barrier is reduced. Consequently, the specific capacity of Se/NbSe 2 @f-Nb 2 C cathode can reach 1128 mAh g −1 at 0.25 A g −1 with stable cycling performance. Additionally, the conversion mechanism is investigated via comprehensive characterizations and density functional theory calculations. This study provides an innovative approach for designing high performance MXene-based catalytic host materials to enhance the conversion kinetics of aqueous Cu-Se batteries.

An electrochemical sensor demonstrating exceptional sensitivity was constructed for bisphenol F analysis. Carbon nanocages and Prussian blue nanocubes were synthesized and then applied to modify a glassy carbon electrode layer by layer, creating the unique sensing platform. The combination of carbon nanocages and Prussian blue nanocubes greatly improved the charge transfer rate and offered a substantial surface area for bisphenol F adsorption. Exhibiting outstanding electrocatalytic performance for bisphenol F oxidation, the as-proposed electrode provided a broad linear range from 0.1 to 500 μM and a low detection limit of 0.03 μM (S/N = 3). The sensor manifested strong selectivity, showing minimal interference from typical coexisting substances. Its stability and reproducibility were evaluated, and the results were satisfactory. The sensor effectively determined bisphenol F in real samples, achieving recoveries between 95.7 % and 98.4 %. This study offers a promising method for the sensitive and precise detection of bisphenol F in environmental samples, significantly contributing to environmental monitoring.

People pay more and more attention to their own health and environmental safety, which makes the monitoring and treatment of harmful amines such as triethylamine (TEA) emitted in the industrial process increasingly critical. In order to address this issue, we focus on the heterostructure construction of two-dimensional rhenium disulfide (ReS 2 ) and acid-functionalized carbon nanotubes (f-MWCNTs), using their unique electronic properties and high specific surface area for triethylamine gas detection. The findings demonstrated that, at room temperature (25°C), the ReS 2 /f-MWCNTs sensor's response to 100 ppm TEA reached 63 %. Under the same environmental conditions (25℃), the response value of the ReS 2 sensor to 100 ppm TEA is 6 %, and the sensing performance is improved by more than 10 times. In addition, the sensor has fast response recovery (73 s/46 s) and good repeatability and stability. Based on this research, we designed a simple detection device, providing a direction for the practical detection application of TEA sensors.

In this study, the effects of various sources polysaccharides, including chitosan, hawthorn polysaccharide and lentinan, on MeIQx (2-amino-3,8-dimethylimidazole[4,5- f ] quinoxaline) formation in roasted beef patties were investigated. Results showed that hawthorn polysaccharide had the strongest inhibitory effect, while only chitosan decreased free MeIQx in a dose-dependent manner. For bound MeIQx, the inhibitory effect of chitosan, hawthorn polysaccharide, and lentinan were 14 %, 22 %, and 39 % at 0.1 % addition. When increased to 0.5 %, the inhibition rate was 26 %, 40 %, and 36 %. None of the polysaccharides increased the inhibition rate of MeIQx at 1 % addition (25 %, 36 %, and 33 %, respectively). Overall, the MeIQx content may be related to the polysaccharides themselves have excellent water retention capability. Additionally, polysaccharides effectively eliminated the intermediates. The carbonyl content and TBARS were reduced due to the free radical scavenging activity of polysaccharides. This study provides a theoretical basis for the polysaccharides to reduce MeIQx in high-temperature meat processing.

Low temperature co-fired ceramics (LTCC) technology is extensively utilized to meet the requirements of device integration and miniaturization. Low-fired Li 3 Mg 2 NbO 6 ceramics doped with x wt% Li 2 O–MgO–B 2 O 3 –CaF 2 –SiO 2 glass (LMBCS, x = 0.5, 1.0, 1.5, 2.0) were prepared by the solid-state reaction method for applications in microwave communication materials. All samples exhibited a single-phase Li 3 Mg 2 NbO 6 structure. The addition of LMBCS glass effectively reduced the sintering temperature of Li 3 Mg 2 NbO 6 ceramics from 1250 °C to 875 °C. And adding LMBCS glass improved the Q × f value of Li 3 Mg 2 NbO 6 ceramics. The Li 3 Mg 2 NbO 6 -1.0wt% LMBCS ceramics exhibited outstanding microwave dielectric properties: ε r = 16.8, Q × f = 89,495 GHz, τ f = − 27.4 ppm/°C at 875 °C, which indicates that this ceramic is potential candidate materials for LTCC.

Hydrogen sulfide (H2S), a characteristic byproduct of sulfur-containing amino acid decomposition during fish spoilage, serves as a critical freshness indicator and poses substantial food safety risks. This study develops a novel H2S gas sensor using a ZnWO4/f-MWCNTs nanocomposite synthesized via one-step hydrothermal method. The incorporated functionalized multiwalled carbon nanotubes (f-MWCNTs) improve the sensing material’s conductivity, dispersion stability, and gas adsorption capacity. XRD, XPS, FTIR, SEM, TEM, and BET analyses verify the composite’s successful synthesis and optimal physicochemical properties. The ZnWO4/f-MWCNTs sensor demonstrates exceptional H2S detection at 120 °C, achieving a response value of 18.67 (Ra/Rg) to 50 ppm of H2S with fast response/recovery times (14 s/30 s) and excellent selectivity against interferents. Real-time monitoring of fish spoilage further confirms its practical utility, highlighting the sensor’s potential for meat freshness assessment and food safety applications.

Conventional pretreatments of star anise ( Illicium verum Hook. f.) often result in uneven color development, long drying duration and substantial aroma losses, hence limiting final product quality and market value. To address these issues, the present study hypothesized that ultrasound-assisted electrolyzed water thawing (UEWT) as pretreatment prior to drying could accelerate drying and enrich flavor of star anise by inducing appropriate structural and biochemical changes. The effects of UEWT were compared with those of deionized water thawing (DWT), electrolyzed water thawing (EWT), ultrasound-assisted deionized water thawing (UDWT), and hot water blanching (HWB), with a focus on drying kinetics, microstructure, relevant enzyme activities, antioxidant activities and volatiles composition of star anise were evaluated. UEWT reduced drying time to 8 h, with the highest drying rate (0.75 kg/(kg·h)), free water content (48 %) and oil-associated NMR signal (23 %). Enhanced cell disruption enhanced moisture migration and volatiles release, while elevated PPO and POD activities intensified desirable coloration ( a* = 27.3; Δ E = 26.8); antioxidants retention was nevertheless compromised (phenolics 45.94 mg GAE/g; flavonoids 2.35 mg GAE/g). UEWT also resulted in the highest content of trans -anethole (1100.40 μg/kg) and formation of α-terpineol, both of which are key contributor to characteristic aroma of star anise. These findings demonstrate that UEWT effectively balances drying rate, color formation, and aroma retention, offering a practical pretreatment for quality-oriented drying of spice fruits. Future studies should optimize ultrasonic parameters and evaluate industrial-scale integration for continuous spice processing.

In this work, a novel dual-excitation and dual-emission fluorescent probe , CDs–COO–Fluorescein (CDs–COO–F), for the specific detection of hydrazine (N 2 H 4 ) was designed and synthesized through esterification reaction of carbon dots (CDs) and fluorescein (F). The prepared CDs were characterized by TEM, XPS , XRD and FT-IR and the optical properties of CDs and CDs–COO–F were described by UV–vis and fluorescence spectra. On the other hand, the affecting factors including hydrazine (N 2 H 4 ) concentration and interfering substances on the hydrazine (N 2 H 4 ) detection were researched. The high sensitivity and high selectivity of CDs–COO–F in detection hydrazine (N 2 H 4 ) could be confirmed. Two good linear responses of fluorescence emission intensities of CDs–COO–F at 462 nm and 515 nm as functions of hydrazine (N 2 H 4 ) concentration were obtained, respectively. The limits of detection hydrazine (N 2 H 4 ) were 0.504 μM and 0.269 μM under 370 nm and 480 nm excitation wavelength lights, respectively. The detecting mechanism of hydrazine (N 2 H 4 ) by CDs–COO–F was deduced from the experimental results. Cell imaging and cytotoxicity experiments of CDs–COO–F were measured. The experiment results show that the fluorescent probe CDs–COO–F can be applied to detect hydrazine (N 2 H 4 ) in aqueous solution and living cells.

Polymeric quaternary ammonium salts (PQAS) have been widely used to prevent microbial contamination, but little is known about their activity against phytopathogenic fungi. Our previous report described the synthesis of two novel PQAS, namely a homopolymer of (2-methacrylamido) propyltetrabenzyldimethylammonium chloride (PQD-BC) and dimethylaminopropyl benzyl chloride-grafted polysiloxanes (PDMS-g-BC); we demonstrated their structure-activity relationship against phytopathogenic fungi such as R . solani and Fusarium oxysporum f. sp. cubense tropical race 4 (Foc4). Here, we analyzed the structure-activity relationship and toxicity mechanism of these compounds at the molecular level against Foc4 compared with the low molecular-weight quaternary ammonium salt benzalkonium chloride (BC). The results revealed that PQD-BC and PDMS-g-BC application inhibited the growth of Foc4 in a concentration-dependent manner and that PDMS-g-BC exhibited higher activity than PQD-BC. In addition, these polymers were found to induce cell death in Foc4 by disrupting the cellular structure integrity, such as the loss of the cell wall and plasma membrane integrity and oxidative stress (lipid peroxidation), leading to the release of intracellular contents and inducing mitochondrial dysfunction and interference with genomic DNA . The newly elucidated mechanism provides possible applications in which PQAS can be used against phytopathogenic fungi.

The development of cobalt-free P2-Na2/3Ni1/3Mn2/3O2cathodes is hampered by poor electrochemical performance, resulting from structural instability during high-voltage cycling. Herein, Li+and F−ions are introduced simultaneously via a simple sol–gel method. The F not only enters the lattice but forms chemically stable NaF on the surface. The modified electrode delivered significantly better electrochemical performance than the pristine one, including much-enhanced capacity retention (64% vs. 36%, 100 cycles) at 0.5 C and a four-time higher capacity output at 10 C. The ex situ XRD and in situ Raman analysis revealed cyclability enhancement mechanisms in terms of inhibiting the P2–O2 phase transition and Na+/vacancy ordering. The conductivity measurements (based on AC impedance and DC polarization) and GITT analysis proved, on both bulk material and electrode levels, that Na+conduction and, thus, rate performance is notably promoted by doping. The individual contribution of Li and F to the overall performance improvement was also discussed. Furthermore, a solid-state sodium-metal battery was successfully demonstrated with the modified cathode. The above results verify that Li+/F−incorporation can enable enhancements in both cyclability and rate capability of the P2-Na2/3Ni1/3Mn2/3O2cathodes and are expected to provide a new perspective for the rational design of high-performance layered oxide cathode materials for progressive sodium-ion batteries.

Achieving a stable interface between sulfide solid-state electrolytes (SSEs) and high-voltage Ni-rich oxide cathodes is crucial for enhancing the electrochemical performance of all-solid-state batteries (ASSBs). However, addressing the interface challenges through surface coating modifications remains a significant hurdle. In this work, a straightforward modification approach is proposed to achieve a highly stable interface by surface dual doping of Zr and F in LiNi 0.83 Co 0.12 Mn 0.05 O 2 (NCM83) cathodes via acid washing followed by annealing. First-principle calculations demonstrate the thermodynamic stability of Zr-F doped NCM83, effectively inhibiting the formation of unfavorable interfaces with decomposition products. The modified NCM83-1% ZrF cathode exhibits exceptional long-cycle stability, retaining 85.1% of its capacity after 1000 cycles at 0.5C rate. This simple and scalable modification strategy offers a new perspective for the design of high-performance sulfide-based ASSBs.

A copper-catalysed cascade ester amidation/radical cyclization of 2-amino-1,4-naphthoquinones with α-bromocarboxylates to afford benzo[f]indole-2,4,9(3H)-triones is described, and the reaction has a broad substrate scope and the desired products are obtained in mostly moderate to good yields. Mechanism-probing experiments indicate that the otherwise challenging radical coupling reaction of α-bromocarboxylates with 2-amino-1,4-naphthoquinones is facilitated by a 5-endo radical cyclization.
