Although hydrogels show immense promise in biomedical and engineering applications, they face critical limitations in mechanical property versatility and inadequately stable anti-swelling capacities. Inspired by the graded structure of articular cartilage—where a dense, wear-resistant outer layer integrates with a compliant, shock-absorbing inner layer—this study proposes a dual-stage reverse-dialysis strategy for fabricating a chitosan/polyvinyl alcohol (CS/PVA) and silk nanofiber/polyvinyl alcohol (SNF/PVA) double-layer biomimetic hydrogel by precisely regulating the internal dialysate (a CS/PVA solution), external polyethylene glycol concentration, and molecular weight to form a soft inner structure. Subsequently, a rigid, densely structured SNF/PVA outer layer was fabricated without requiring any chemical crosslinkers, synergistically enhancing the mechanical property of the hydrogel: The compression strength surged from 345.07 to 2490.23 kPa (for the single inner and double layers, respectively) at 70 % strain by optimizing the solution concentration and enhancing the mechanical properties of the outer hydrogel. Crucially, this method enables robust, chemical-crosslinker-free interfacial bonding (shear strength >390 kPa) through physical crosslinking, overcoming weak interlayer adhesion in conventional methods. The hydrogel exhibits exceptional anti-swelling properties (mass swelling ratio = 24.55 % after 168 h) and resilience (91.47 % stress retention over 10 compression cycles). This strategy provides a green and scalable route to develop structurally stable, double-layer hydrogels.

Alternaria alternata causes serious postharvest diseases in tomatoes, threatening shelf life and food safety. In this study, a natural and eco-friendly strategy was developed using Ligusticum jeholense essential oil (LEO), extracted via optimized enzymatic–deep eutectic solvent microwave-assisted method (EDP–MAHD), which achieved a 3.38-fold higher yield than conventional extraction. GC–MS analysis confirmed consistent chemical composition across production batches. In vitro , LEO exhibited potent antifungal activity against A. alternata (IC₅₀, 0.0718 μL/mL), while in vivo experiments on tomato fruit showed it significantly inhibited lesion expansion and suppressed the accumulation of mycotoxins, alternariol (AOH) and tenuazonic acid (TeA). SEM, TEM, proteomic, and physiological analyses revealed that LEO disrupted membrane integrity, interfered with energy metabolism, and induced oxidative stress, suggesting multi-target antifungal mechanisms. Acute toxicity in mice confirmed its safety. These findings support the application of LEO as a promising natural preservative for postharvest disease and toxin control in tomatoes.

In this work, we developed a piezoelectric cantilever energy transducer integrated with a self-oscillating polymer gel (NPC-Rux). The gel features a dual-crosslinked network—combining physical crosslinker (Laponite XLG) and chemical crosslinker (N,N′-Methylene diacrylamide (MBA)) - for improved structural stability. Grafting with hydrophilic 2-Hydroxyethyl acrylate (HEA) enhanced its swelling capacity in the oxidized state, enabling a large volume oscillation amplitude of up to 64 μm during the Belousov-Zhabotinsky reaction (B-Z reaction). A flush-type coupling structure was designed to directly transfer the gel's deformation to a Polyvinylidene fluoride (PVDF) piezoelectric cantilever. This configuration achieved a voltage output between 0.17 V and 0.23 V under mechanical stresses from 6.64 × 10 −3 N to 11.54 × 10 −3 N, establishing an effective chemo-mechano-electrical energy conversion pathway. The system enables real-time monitoring of both gel volume changes and electrical signals, offering promising applications in self-powered sensors and adaptive soft robotics.

Lignocellulosic biomass, which consists primarily of
cellulose,
hemicellulose, and lignin, is a promising renewable feedstock for
producing high-value biobased amines. In this study, an integrated
chemobiocatalytic strategy was developed to synthesize furfurylamine
from corncob using a newly formulated deep eutectic solvent, [Bet][FA][LA],
that provides both catalytic and solubilizing functions. Under optimized
conditions, corncob was efficiently converted into furfural, which
was subsequently aminated by recombinant Escherichia coli BM-AlaDH coexpressing an ω-transaminase
and alanine dehydrogenase. The whole-cell catalyst enabled in situ
regeneration of L -alanine, thereby reducing amine-donor
requirements and improving biocatalytic efficiency. Integration of
[Bet][FA][LA]-mediated chemocatalysis with whole-cell biocatalysis
converted corncob into furfurylamine in [Bet][FA][LA]. The biocatalytic
amination system could convert biomass-derived 5-hydroxymethylfurfural
(320 mM) and vanillin (20 mM) into the corresponding amines in yields
of 95.4% and 91.0%, respectively. This work establishes a sustainable
route for converting lignocellulose-derived aldehydes into value-added
biobased amines and advances the comprehensive valorization of lignocellulosic
biomass.

By virtue of the inherent safety, decent power density and low manufacturing cost, zinc-ion hybrid supercapacitors (ZHSCs) are considered as compelling candidates for future energy storage. However, their practical implementation is impeded by a bottleneck due to the limited energy density of commonly used carbon cathodes. In this study, a newly designed porous carbon nanonecklace is proposed for the first time, which is developed by exquisitely threading the silk nanofibrils (SNFs) based N-doped carbon ‘nanochains’ into the metal-organic frameworks (MOFs) based N-doped porous carbon ‘nanobeads’. The necklace-like carbon/carbon structure effectively mitigates agglomeration, realizes multi-dimensional electron transport, and leads to a BET specific surface area of 1367.4 m 2 g −1 , which shows an astounding 19.6% increase in comparison to the control product (1143.5 m 2 g −1 ). When used as a cathode for ZHSCs, MPCN-150–800 exhibits a superior specific capacitance of 270.4 F g −1 , exceptional high-rate capability (57.4% capacitance retention at a 50-fold higher current density), excellent energy density of 96.1 Wh kg −1 at 159.9 W kg −1 and superb cyclic stability with 90.9% capacitance retention after 10,000 cycles at 2 A g −1 . The performance outperforms numerous counterparts fabricated so far, greatly highlighting the creative synthesis of MPCN-150–800. This work delivers a new paradigm for the design and fabrication of advanced carbon cathodes, which may boost the current state-of-the-art properties of ZHSCs.

Circularly polarized luminescence (CPL) materials are highly sought after for their unique chiroptical properties, but their rational design remains challenging. To address this, a machine learning (ML) platform that intelligently screens deep eutectic solvents (DES) for crafting G-quartet-based gels with tailored CPL is established. An ML classifier trained on experimental data predicts CPL activity with 0.916 accuracy. SHapley Additive exPlanations (SHAP) analysis identifies key DES molecular descriptors, guiding the discovery of novel materials that exhibit a record-high luminescence dissymmetry factor (g lum ) of 0.222 for nucleotide-based systems and achieve chirality inversion via DES modulation. The Sure Independence Screening and Sparsifying Operator (SISSO) algorithm further yields interpretable design formulas. Leveraging the distinct polarization of these gels, we demonstrate a fourth-level anti-counterfeiting strategy, decrypting concealed information via Morse and ASCII codes to enhance information security. This ML-driven methodology accelerates the discovery of high-performance CPL materials and opens new design avenues.

It remains challenging to improve the quality standard system of Traditional Chinese Medicine (TCM) for TCM development. Currently, it is urgently needed to develop an integrated, effective, and scientific approach to improve the efficacy, safety, and quality consistency of sporoderm-broken spores of Ganoderma lucidum (SSGL). In this study, high-performance liquid chromatography (HPLC) was applied in combination with electrochemical (EC) technologies for constructing a multidimensional fingerprint (FP) to comprehensively assess SSGL samples. First, an EC FP (EC-FP) was constructed with the B-Z oscillation system; thereafter, eight representative parameters of this system were obtained and compared across the 15 samples. Furthermore, an HPLC FP (HPLC-FP) was also built for further analyzing the representative parameters. Subsequently, the systematically quantified FP method (SQFM), principal component analysis (PCA), hierarchical clustering analysis (HCA), and orthogonal partial least squares method−discriminant analysis (OPLS-DA) were employed for classifying distinct samples and comparing the results between HPLC-FP and EC-FP. The two approaches complemented one another and successfully distinguished samples from various sources. In conclusion, bivariate correlation analysis (BCA) was employed to examine the relationships between FP and efficacy for both HPLC-FP and EC-FP. A linear correlation ( r ≥ 0.800) between peak top potential (Epet) and HPLC peak area suggested that Epet might be used to predict chemical content. This novel method innovates detection dimensions, transcends single-mode detection for trace bioactive components in complex matrices, and expands EC detection’s frontier in separation science. In the present work, HPLC-FP and EC-FP contribute to detecting the SSGL quality, which offers a new way for improving the SSGL quality standard and studying its quality standard method.

A rapid, selective, and sensitive paper-based fluorescence sensing method was developed for cysteine (Cys) detection. The nitrogen-doped carbon quantum dots (CNQDs) and aspartic acid (Asp) reacted with gold nanoparticles (AuNPs) to synthesize the probe AuNPs@CNQDs@Asp, resulting in an efficient quenching of CNQDs fluorescence. Owing to the strong interaction between Cys and AuNPs, as well as the specific interaction between Cys and Asp, triggering the detachment of CNQDs and the recovery of fluorescence. The images of fluorescence signal were collected within 6 min using a portable fluorescence detector and analyzed via a smartphone-based application. The RGB value increased linearly in the 180 to 260 μM Cys concentration range (R = 0.9990), with a low limit of detection (LOD) of 4 μM. Interference deviations of 12 substances to Cys were in the range of −3.1% to +1.0%. The method was applied to determine Cys in human plasma, showing a recovery between 98.2% and 102.3% and demonstrating its superior reliability. The work highlights the potential of the method to detect Cys in real samples with low cost and high efficiency, providing an effective tool for diseases surveillance and control in resource-limited regions.

In this study, an amorphous carbon-rich carbon nitride photocatalyst was prepared by nitric acid treatment of pyrolyzed melamine followed by nitrogen annealing. The resulting semiconductor material exhibited an up-shifted valence band that enhances the oxidizing power of photogenerated holes, enabling selective C α −C β bond cleavage of 2-phenoxy-1-phenylethanol (2-POE). Using 1.5 g L −1 of the optimized photocatalyst in acetonitrile, 2-POE underwent first-order conversion with a reaction rate of 2.55 h −1 under a 9 W blue LED light source. Product analysis showed the formation of benzaldehyde as the major product, confirming C−C bond scission with 93.1% selectivity. In addition, ring-opening reactions were observed, producing fumaric and maleic acids as the by-products. Photocatalytic depolymerization of organosolv lignin further demonstrated ring opening of the β-O-4 linking motifs, forming dicarboxylic acids analogous to those generated from 2-POE. These demonstrate a metal-free photocatalytic platform capable of promoting β-O-4 bond cleavage in lignin model compounds and inducing photocatalytic structural modification of organosolv lignin, accompanied by the formation of low-molecular-weight aliphatic dicarboxylic acids.

Although the preparation of silver nanosheets (AgNSs) through diverse methods has largely advanced over the past few decades, the simple and efficient synthesis of high-quality AgNSs under mild conditions remains challenging. Herein, we report a strategy for preparing rounded and sharp-cornered AgNSs with uniform thicknesses of 30–40 nm via simple liquid-phase reduction. Structural characterization revealed that the reduction reaction rate was mediated by coordination of silver ions with the amino groups of gelatins and the carboxylate ions of glutaric acid (GA), effectively suppressing burst nucleation. Density functional theory calculations further identified the adsorption preference of GA anions on Ag(111) as the key factor that dictates the anisotropic growth of silver nanosheets. Furthermore, selective etching with hydrogen peroxide (H2O2) mediates the morphological evolution of AgNSs from rounded to sharp-cornered morphologies, effectively removing byproduct particles to achieve sharp-cornered AgNSs in yields exceeding 90%. Catalytic performance testing of the hydrogenation of 4-nitrophenol (4-NP) to 4-aminophenol (4-AP) indicates that the mass-normalized rate constants reached 156.67 and 154.22 s–1 g–1 for the rounded and sharp-cornered AgNSs, respectively. The conversion rate of 4-NP decreased by only about 2% after five consecutive catalytic cycles. This work provides guidelines for the efficient, economical, and green synthesis of two-dimensional metal nanomaterials while offering valuable insights into the application of the AgNSs in the catalytic reduction of 4-nitrophenol.

Photocatalytic methanol dehydrogenation affords HCHO and H 2 , capable of replacing the current methanol oxidation technologies for HCHO production. However, the charge transfer from bulk of photocatalyst to methanol and intermediates has barrier, leading to quantum efficiency far from 100 %. Herein, we synthesized TiO 2 -supported Pt single atoms (Pt 1 /TiO 2 ) that works as an electron shuttle to promote electron extraction from the bulk of TiO 2 and transfer it to protons. The Pt 1 supported on TiO 2 reduces the migration energy of electrons from 0.57 to 0.23 eV, thus fostering electron extraction from bulk of TiO 2 to surface. Electrons trapped on Pt 1 active sites can be transferred to protons for H 2 evolution. Therefore, the Pt 1 /TiO 2 produces H 2 and HCHO from methanol with formation rates of 102.8 and 80.4 mmol g catal. −1 h −1 , respectively, which are 1.7 folds of Pt/TiO 2 prepared by an impregnation method. The quantum efficiency of methanol dehydrogenation is 52 % at ambient temperature and increased to 84 % at 75 °C. This study offers fundamental insights into charge extraction and transfer mechanisms for dehydrogenation reactions.

Polar crystal materials hold significant potential for advanced scientific and technological applications; however, their synthesis remains challenging due to stringent symmetry requirements. In this work, flexible π-conjugated malonate groups with high polarity and diverse conformations were employed as polar functional basic modules (FBMs) to overcome this challenge. Three new crystals, RbLi(C3H2O4)·H2O, Rb2Li(C3H3O4)3·H2O, and C(NH2)3(C3H3O4), were successfully synthesized via a deprotonation-regulated conformational switching strategy. Remarkably, all three compounds crystallize in polar space groups and simultaneously exhibit strong second-harmonic generation responses (1.5–3.0 × KH2PO4 (KDP)), large birefringence (0.043–0.163@546 nm), and short UV cutoff edges (230–244 nm). This study not only discovers three promising UV polar crystals but also elucidates the conformational evolution of malonate-based FBMs, offering valuable guidance for the rational design of new polar crystal materials.
