Understanding the unidentified characteristic aroma compounds of oil furu would improve the ability to control the process and to determine the geographic origin of traditionally fermented soybean products. The characteristic aroma compounds of oil furu were identified using HS-SPME-GC/MS and a sensomics approach. The microbial communities and their functional dynamics during oil furu fermentation were analyzed using metagenomics and untargeted metabolomics. A total of 102 aroma compounds were identified, with 11 being determined to be the characteristic aroma-active compounds of oil furu. Microbial structure and function analysis showed that Lactobacillus , Limosilactobacillus , Enterobacter , and Klebsiella were the dominant microbial communities throughout the fermentation process, and they collectively contributed ∼88 % to KEGG pathways. Bacteria showed stronger and more positive genus-metabolism correlations than Eukaryota, and the characteristic metabolites were mainly involved in lipid and amino acid metabolism. The identified characteristic aroma compounds could enhance the understanding of the microbial contributions, and this may facilitate the construction of starter cultures by building synthetic microbial communities to produce fermented food with desirable aroma properties.

The world is currently facing the dual challenges of energy scarcity and environmental degradation. As a highly promising carrier of clean and renewable energy, hydrogen has attracted significant attention, with high-efficiency water electrolysis recognized as a key pathway for the large-scale production of green hydrogen. Among various electrocatalysts, transition metal Co-V-based materials demonstrate remarkable potential. In this study, we successfully synthesized a highly stable amorphous Co-V-B catalyst on a nickel foam (NF) substrate by constructing a Co-V bimetallic system followed by boron doping to enhance its performance. Electrochemical evaluations indicated that the catalyst delivers superior Hydrogen evolution reaction (HER) performance, requiring only 47 mV overpotential to attain a current density of − 10 mA cm −2 , along with a low charge transfer resistance of 1.14 Ω. Additionally, the catalyst demonstrated remarkable durability, sustaining stable HER activity during 16 h of continuous chronopotentiometric (CP) operation. This study systematically explores the preparation of Co-V/NF catalysts and highlights the significant impact of boron incorporation on improving catalytic performance, providing meaningful guidance for developing advanced electrocatalysts for water splitting applications.

The rapid advancement of smart agriculture has created a growing demand for innovative materials capable of real-time environmental monitoring. In this study, starch/carboxymethyl cellulose/cresol red (SCR, CMCCR, SCMCCR) composite films were developed using a casting method to explore the effects of pH-responsive reagents at 0.3 wt% content on the films' physicochemical properties. The SCMCCR film showed a 20.26 % reduction in thickness compared to the SCR film, while its density increased by 26.6 %. Mechanical testing revealed that the tensile strength improved by 17.38 %, and the elongation at break remained at 52.56 %. Notably, the SCMCCR film achieved a Young's modulus of 552.96 MPa, which is over 6 times higher than that of the CMCCR film and 23 times greater than that of the SCR film. Water solubility of 27.77 % and enhanced thermal stability, with a final residual content of 49.57 % at 600 °C, were observed for the SCMCCR film. Characterization by FT-IR, XRD, and SEM confirmed structural and morphological modifications. The films raw materials exhibited exceptional responsiveness to humidity variations and film demonstrated rapid and distinct color transitions from yellow to purple across specific pH value. The environmentally friendly composition, low cost, and high sensitivity of these films make them promising candidates for real-time soil pH monitoring.

The SiO 2 –B 2 O 3 –Bi 2 O 3 –CaO (SBBC) luminous glass samples, co-doped with Tm 3+ , Dy 3+ , and Eu 3+ ions, were prepared. Upon 362 nm stimulation, the co-activated SBBC glasses exhibited distinct spectral transitions corresponding to Tm 3+ : 1 D 2 → 3 F 4 , Dy 3+ : 4 F 9/2 → 6 H 15/2 , 13/2 , as well as Eu 3+ : 5 D 0 → 7 F 2 in the 400–700 nm. Moreover, the study identified two significant energy transfer mechanisms, Dy 3+ →Tm 3+ and Dy 3+ →Eu 3+ , which contribute to the enhanced photoluminescence of the glasses. The optimal CIE coordinates were determined to be (0.3312, 0.3436), with CCT of 5552 K, as well as color purity of 2.55 %. Importantly, an investigation into the thermal stability of selected glass revealed an impressive ΔT of 140 °C. This study shows the potential value of glass in the field of W-LED.

In this work, the nanomagnetic probe was prepared by condensation of carboxylated kanamycin (Kana) aptamers with aminated nanomagnetic Fe 3 O 4 beads, which was coupled with invertase-labeled complementary DNA (cDNA) for sensitive and convenient detection of Kana in water sample by a personal glucose meter (PGM). In the absence of Kana, there was no PGM signal recorded because formed nanomagnetic probe was removed by magnetic separation. Conversely, the aptamer could recognize Kana specifically and released cDNA into supernatant. After the addition of sucrose, it was hydrolyzed into glucose by invertase. Detection of Kana was indirectly achieved based on the relationship between glucose concentration and the PGM indication. Furthermore, a miniaturized portable device was constructed by integrating the components using 3D printing technology. Under optimal conditions, rapid detection of Kana within the concentration range of 1-200 nM was achieved, with a detection limit ( 3σ/k ) of 0.28 nM. Moreover, the proposed aptasensor was characterized in terms of selectivity, reproducibility and stability. Finally, it was applied to the determination of Kana in water with recoveries from 99% to 103%. All these results indicated that the proposed aptasensor is simple, rapid, selective, and sensitive, and it could potentially serve as an effective approach for the on-site determination of Kana in water samples.

The practical application of unmodified biochar in advanced oxidation processes (AOPs) is constrained by its limited surface functional groups and the inherent drawbacks of nanoscale zero-valent iron (nZVI), including particle aggregation and oxidative instability. To address these challenges, nZVI catalysts with controlled boron doping ratios were synthesized via coffee grounds modification, followed by systematic evaluation of their catalytic performance, mechanistic pathways, and operational parameters. Under optimized conditions (0.12 g L −1 nZVI@B 1 -BC and 1 mM peroxymonosulfate (PMS)), near-complete tetracycline (TC) removal (99.1 %) was achieved within 30 min. Remarkably, boron doping enhanced TC degradation kinetics by 1.51-fold compared to undoped counterparts, highlighting the pivotal role of heteroatom engineering in tailoring catalyst reactivity. The nZVI@B 1 -BC composite demonstrated exceptional robustness across diverse aqueous matrices, exhibiting strong tolerance to coexisting anions, humic acid (up to 25 mg L −1 ), and pH fluctuations (3−11). Radical quenching experiments and electron paramagnetic resonance (EPR) analysis identified hydroxyl radicals (•OH) and sulfate radicals (SO 4 •− ) as dominant reactive oxygen species (ROS), while HPLC-MS elucidated three potential TC degradation pathways involving dehydroxylation, demethylation, and ring-opening reactions. This work advances the rational design of biochar-supported nZVI catalysts and provides actionable insights for optimizing persulfate activation systems in antibiotic-contaminated water remediation.

Natural wood is a pervasive sustainable structural material with efficiency, aesthetically pleasing, usefulness, and durability, which is widely used in building construction. However, the fire safety of wood is unsatisfactory for many advanced engineering structures and applications. To address this issue, a highly fire-safe wood hybrid was developed, inspired by transparent wood, through partial delignification and co-impregnation with multi-component flame retardants. The results showed that partial removal of lignin from wood (∼5 wt%) significantly increased the loading of flame retardants from 70 wt% to 133 wt%. Furthermore, it provided exceptional self-extinguishing and fire retardancy to the wood hybrid. The vertical burning test revealed that the wood hybrid did not self-propagate when directly exposed to an open flame and rapidly self-extinguished when removed from the igniting flame. Notably, it did not ignite at an external heat flux of 50 kW/m 2 (cone calorimetry experiment), and the recorded peak heat release rate was reduced by more than 85 % compared to the original wood. It is demonstrated that the co-impregnation of guanidine phosphate and boric acid modifies the thermal decomposition pathway of wood hybrid during burning, allowing the wood to form homogeneous and dense char residues. These carbonaceous structures were embedded with phosphate and borophosphate species, which provide the char residues with improved resistance to oxidation and higher thermal stability, preventing heat and oxygen from infiltrating the underlying wood. In summary, this work provides a facile delignification and co-impregnation strategy that greatly improves the fire retardancy of wood and represents a promising approach toward highly fire-safe structural materials.

The microscopic particles present in the primary coolant of a nuclear power plant, when activated, have radioactivity that can affect the safety of the plant’s operation and the radiation dose of the workers. Traditional filtration materials only use mechanical interception to achieve the removal of small particles, which causes the initial filtration resistance to increase continuously, reducing the service life of the filter material. The element leaching rate is also an important indicator of the performance of the filter material. Since the filter material itself leaches Si 4+ , it will combine with Ca 2+ , Mg 2+ , and Al 3+ ions in the coolant to form negative temperature coefficient silicates, which can form dense deposits at the hottest part of the fuel element bar, affecting the reactivity and fuel performance of the core. The leached SO 4 2− can cause intergranular corrosion on pipe materials, which has a significant impact on the service life of equipment. In this paper, nano-scale Al powder (50 nm) was used as raw material to successfully prepare AlOOH crystal by one-step hydrothermal method, which was grafted on the surface of glass fiber to prepare glass fiber filter material with high positive Zeta potential, and the method combining mechanical filtration and electrostatic adsorption was realized to remove small particles. At the same time, the leaching of Si 4+ and SO 4 2− was decreased. The experimental results showed that the filtration effect of the modified filter material for 0.45 μm particle size increased from 86.83 % to 99.95 %, and the 14-day Si 4+ leaching concentration decreased by 73.17 % and the 14-day SO 4 2− leaching concentration decreased by 84.43 %. This research helps advance the development of advanced materials that can withstand the harsh environment of nuclear energy systems, providing a reliable solution to ensure coolant purity and the safety of the entire reactor.

Microelectronics manufacturing generates substantial wastewater, containing toxic contaminants. Although the reverse osmosis (RO) membrane is a promising treatment technology, its suboptimal water permeance and limited rejection of low-molecular weight (MW) organic contaminants restrict its practical application. Herein, we present a simple approach for developing RO membranes fabricated via interfacial polymerization with boric acid as an additive, which enhances the water permeance and superior removal efficiency for low-MW contaminants in microelectronic wastewater. The boric acid-modified RO membranes exhibited a remarkable increase in water permeance up to ∼4.2 L/(m2·h·bar), a 3-fold enhancement compared to the pristine membrane thanks to the formation of smoother and thinner polyamide (PA) layers. Meanwhile, owing to the denser PA layers, the modified membranes reached a 2–18% higher removal efficiency for common low-MW contaminants in microelectronic wastewater compared to the commercial membranes. The penetration of organic substances through the modified membranes in real wastewater was decreased by 50% with respect to that of the commercial membranes. The hydrogen bonding interaction between the amine monomer and boric acid, along with the buffering effect of boric acid, collectively promoted the formation of denser and thinner PA layers. This study offers valuable insights into the development of RO membranes for the recovery of microelectronic wastewater or analogous effluents containing low-MW contaminants from the perspective of interfacial polymerization regulation.

SiOC ceramics, characterized by excellent chemical stability, tunable dielectric properties and remarkable high-temperature stability, are promising candidates for next-generation wave-absorbing materials. However, the current performance of SiOC-based materials in terms of electromagnetic wave absorption is limited by their inherent lack of good impedance matching. In this study, we successfully synthesized SiTiBOC ceramics at 1400 °C utilizing a straightforward polymer-derived ceramic method. The impedance matching was effectively enhanced to Z ≈ 1 through the strategic doping of Ti and B elements, facilitated by the intrinsic spatial gaps within the material. Electromagnetic parameter analysis revealed that the minimum reflection loss (RL min ) value of SiTiBOC ceramics is −61.58 dB at a frequency of 10.70 GHz, while the effective absorption bandwidth (EAB) is 2.70 GHz (t = 1.7 mm, 15.21–17.91 GHz). The radar stealth capabilities of SiTiBOC ceramics were evaluated via radar cross-section (RCS) modeling, revealing an RCS reduction of 10.15 dB·m² at 0° and a minimum RCS value of −55.2 dB·m² at −45° compared to a perfect electrical conductor (PEC). These excellent properties make SiTiBOC ceramics a potential candidate for a new generation of highly efficient wave-absorbing materials.

A metal-free carbon catalyst co-doped with boron and silicon (2B-BCSi) is designed and synthesized in this work. Its custom-engineered internal electric field achieves the barrier-free and selective generation of singlet oxygen ( 1 O 2 ). Guided by theoretical analysis and density functional theory (DFT) calculations, low‑electronegativity heteroatoms were incorporated into the carbon scaffold to an adjacent electric‑field configuration (B δ+ -C-Si δ+ ). By generating an internal electric field-induced molecular tension and leveraging boron-moderated charge transfer, the system circumvents the adsorption constraints of terminal oxygen that limits traditional approaches. Thereby, it facilitates 1 O 2 production from PMS via a novel barrier-free pathway, resulting in unprecedented selectivity for 1 O 2 (>93.6 %). This system demonstrates significant advantages in electron-rich pollutant degradation (0.437 min −1 ) and organic synthesis (242.8 mg h −1 L −1 ), establishing an electric-field engineering paradigm for precise ROS control while providing dual-path solutions for environmental remediation and value-added chemical production.
