The performance of moisture electricity generators is highly dependent on environmental humidity, and arid environments induce rapid water loss, limiting their stability and lifetime. Herein, we report a bioinspired smart moisture electricity generator that emulates the stomatal regulation of plants and integrates a thermo-responsive poly(N-isopropylacrylamide) (PNIPAm) coating, a photothermal g-C₃N₄@TiO₂ hydrogel, and asymmetric electrodes on a flexible substrate. The PNIPAm layer undergoes a reversible contact angle transition near its lower critical solution temperature, where hydrogen bonding below this temperature enhances water retention, while its disruption above the lower critical solution temperature causes structural collapse, thereby suppressing moisture evaporation. Meanwhile, the C₃N₄@TiO₂ hydrogel converts sunlight into heat, activating the thermo-responsive behavior of PNIPAm. As a result, the MEG exhibits enhanced output under arid conditions (T > 40 °C and RH < 10%), with the voltage increasing from 0.78 V to 0.81 V and the current density from 46 μA cm −2 to 80 μA cm −2 , while the operational lifetime extends from 32 h to 62 h, nearly twice that of the MEG without the PNIPAm layer.

A core–shell magnetic surface molecularly imprinted polymer (MIP) was synthesized using chitosan-modified Fe 3 O 4 nanoparticles (Fe 3 O 4 @CS) as the support and Schisandrol A as the template for selective recognition. After optimization of adsorption conditions, static and dynamic binding experiments demonstrated high selectivity toward Schisandrol A, with an imprinting factor of 4.556. Based on this material, a magnetic solid-phase extraction coupled with high-performance liquid chromatography (MSPE–HPLC) method was established for the enrichment and quantitative determination of Schisandrol A in Schisandra chinensis , achieving a limit of detection of 0.59 ng/mL and a limit of quantification of 2.47 ng/mL. The practical applicability of the MIP was further evaluated by selectively depleting Schisandrol A from the herbal extract, followed by assessment of hepatoprotective activity using an ethanol-induced fatty liver zebrafish larva model. Comparative analysis of hepatic lipid accumulation and biochemical markers (AST, ALT, and SOD) revealed that removal of Schisandrol A significantly reduced the hepatoprotective efficacy of the extract, confirming its functional contribution. These results demonstrate that the proposed MIP-based MSPE–HPLC strategy provides a robust analytical tool for selective lignan analysis and enables component-specific functional evaluation in complex herbal systems.

The formation of low molecular weight lignin nanoparticles (LMW-LNPs) remains challenging due to their severe self-aggregation effect as well as thermal instability, hindering their scalability and functional applications. This study develops a novel γ-valerolactone (GVL)/deep eutectic solvent (DES) biphasic system incorporating polyol-based hydrogen bond donors (HBDs) to systematically modulate the hydrogen bond acidity of DES, enabling selective depolymerization of industrial lignin in acid lithium bromide hydrate (ALBTH) while effectively suppressing lignin condensation. The optimized system achieved a low lignin molecular weight of 1213 g/mol with minimal condensation, yielding monodisperse low-molecular-weight lignin nanoparticles (LMW-LNPs) with an average diameter of 92.3 nm. Mechanistic investigations using the veratrylglycerol-β-guaiacyl ether (VG) model compound revealed that lignin aryl ether bonds are cleaved via hydrogen transfer from the DES-HBD component, which disrupts the condensation pathway through competitive hydrogen bonding. The LMW-LNPs which maintain structural integrity while achieving depolymerization during the preparation of lignin-based materials exhibit efficient photothermal conversion and dye adsorption properties. They offer a transformative approach for the sustainable production of functional lignin nanomaterials with customized properties, addressing key challenges in the value-added utilization of lignin and promoting advanced applications of lignin-based materials.

Owing to their superior mass and heat transfer performance, microreactors have emerged as a research hotspot in novel intensified equipment in recent years. This study experimentally investigates the gas–liquid flow behavior and mass transfer characteristics in microchannel reactors for viscous systems, focusing on the effects of superficial gas and liquid velocities, viscosity, and spiral turbulence elements on T-type microchannel reactors (T-MCRs). Four flow regimes are identified in the T-MCR, where viscosity significantly influences regime distribution and Taylor bubble morphology. In contrast, the spiral-wired T-MCR (T-MCR-SW) is dominated by “serpentine Taylor flow”. Increased viscosity leads to elevated pressure drop and reduced CO2saturation in both reactors, with the T-MCR-SW exhibiting a notably higher pressure drop. The impact of gas–liquid flow rates on CO2saturation varies with reactor type and viscosity. The total volumetric mass transfer coefficient (KLa) of the T-MCR-SW is substantially higher than that of the T-MCR, but its pressure drop is nearly doubled. Thus, a balance between mass transfer efficiency and energy consumption must be considered for practical applications. This work provides valuable insights for the design and optimization of microreactors in viscous systems.

The development of hydrogen evolution reaction (HER) catalysts operating under high current densities is critical for advancing industrial water electrolysis toward green hydrogen production. Herein, we report an ultra-stable hierarchical electrocatalyst Ru/(Ni 1- x Ru x )OOH on anodized nickel mesh (ANM) via a facile two-step anodization-substitution strategy. The catalyst features dual Ru active sites: lattice-doped Ru 3 + within the NiOOH framework and surface-deposited metallic Ru nanoparticles (NPs), supported by a hierarchical porous architecture derived from anodization. The optimized Ru/(Ni 1- x Ru x )OOH catalyst exhibits exceptional alkaline HER activity, with a low overpotential of 81 mV at 100 mA cm −2 . More importantly, it shows remarkable stability at a large current density of 1 A cm −2 for 500 h with a current decay rate of 0.1 mV h −1 , outperforming most of the state-of-the-art HER electrocatalysts. In situ Raman spectroscopy and density functional theory (DFT) calculations show that Ru 3+ doping modulates the electronic environment of NiOOH lattice O atoms, which accelerate H 2 O dissociation and generate H* intermediates adsorbed on O sites (*H-O). Thereafter, H* spills over to adjacent Ru NPs via Ni-O-Ru bonds, forming adsorbed *H-Ru 0 intermediates. These *H-Ru 0 species then accept electrons from Ni, which drives their recombination into H 2 . Additionally, weakly hydrogen-bonded interfacial water (2-HB-H 2 O and free-H 2 O) ensures a continuous supply of reactant to the active sites. This work provides a strategy for designing Ni-based electrocatalysts with tailored active sites and hierarchical structures, advancing alkaline water electrolysis at industrial-level current densities.

Astragali complanati Semen (ACS) is frequently used as Chinese medicines and functional foods. Complanatoside A (CA), a key bioactive phytochemical isolated from ACS, exhibits broad-spectrum pharmacological properties. This investigation systematically formulated sixteen natural deep eutectic solvent (NADES) systems by combining three hydrogen-bond acceptors with eleven hydrogen-bond donors at varying molar ratios. These NADES formulations were subsequently employed in tandem with ultrasonic-assisted extraction to isolate CA. Optimization studies identified the following parameters as most effective for extraction using the L -proline/levulinic acid-based NADES (molar ratio 1:2): 60℃, 30 min, 40 % water content, liquid-solid ratio 25 mL/g, achieving an extraction yield of 1.57 %. The adsorption and desorption conditions were optimized employing a macroporous resin for the recovery of CA, while the reusability of the NADES solvent was thoroughly evaluated throughout the extraction process. The CA extract exhibited significant tyrosinase and α-glucosidase inhibitory activity. These findings establish ultrasound-assisted NADES extraction as a sustainable methodology for efficient extraction of CA from ACS, providing valuable insights for eco-friendly extraction and pharmacological exploitation of plant-derived bioactives.

The simultaneous extraction of bioactive compounds with differing polarities from plant matrices remains a significant challenge. This study was conducted to overcome the drawbacks of traditional extraction methods for the precious medicinal herb Hedyotis diffusa (HD), such as their low extraction efficiency, incapacity to completely utilize HD, and instability of active ingredients. To this end, a biphasic DES with ultrasound assistance was developed for the simultaneous extraction of high-value iridoids and triterpenes from HD. Following a thorough screening process that encompassed 56 two-phase combinations, the choline chloride-acetic acid (ChCl-Aa)/L-menthol-n-octanoic acid (Men-Oa) system was identified as the optimal formulation. Through the implementation of polarity regulation and response surface methodology, this optimal biphasic DES attained extraction yields of 15.65 ± 0.19 mg/g for five target compounds under mild conditions (41.65 °C, 30.71 min, liquid-solid ratio 15.73 mL/g, hydrophilic-to-hydrophobic phase volume ratio 0.77), which is a 2–3-fold improvement over traditional extraction methods. Characterization results indicated that the DES facilitated target release primarily by forming hydrogen-bond networks, which not only enhanced solubilization but also contributed to the disruption of cell wall. This disruptive effect was further augmented by the biphasic interface generated under ultrasonication, leading to significantly improved extraction efficiency. This strategy establishes a green and efficient approach for the valorization of plant resources.

Forming giant aggregates with surfactants in nonaqueous solvents is typically challenging due to weak solvophobic interactions. In this study, a series of phenylalanine-based surfactants—alkyl phenylalanine amide oxides (Cn-Phe-AO, n = 12, 14, 16)—were synthesized. These surfactants independently induced gelation of glycerol at remarkably low concentrations of 22.5, 12.7, and 10 mM, respectively, compared with other glycerol systems. The zero-shear viscosity of a 10 mM C16-Phe-AO glycerol solution reached 10,501 Pa·s. Cryogenic transmission electron microscopy (cryo-TEM) and circular dichroism (CD) confirmed the formation of left-handed helical structures, which account for the pronounced viscoelasticity of the glycerol solutions. The phenylalanine residue promotes regular molecular packing within the aggregates, enabling the formation of robust helical assemblies in glycerol that maintain a densely entangled network. Comparative analysis of aggregation in glycerol and 1,3-propanediol revealed that the hydrogen-bonding capability of the solvent is the primary driving force for the development of elongated micellar aggregates. This study establishes a model system for gelled glycerol solutions with minimal surfactants and offers new insights into molecular self-assembly in nonaqueous media.

Bioinspired intelligent surfaces enable real-time sensing and adaptive functional regulation via stimuli-responsive mechanisms, and are increasingly important for the development of embodied intelligence and intelligent wearable devices. However, most existing bioinspired intelligent surfaces operate under a single-stimulus paradigm, which limits their ability to function in coupled multiphysics environments. Moreover, integrating multi-stimulus responsiveness into the design-to-manufacturing pipeline in an energy-efficient and high-throughput manner remains a major bottleneck in this field. To address these challenges, we employed magnetically assisted assembly to fabricate a triple-responsive bioinspired intelligent surface (TRBIS) that enables coupled photo-, thermal-, and magnetic-responsive behaviors. TRBIS is constructed from a thermoresponsive shape-memory polyurethane (SMPU) composite incorporating carbonyl iron powder (CIP), which provides magnetic actuation and photo-thermal conversion. Before curing, an external magnetic field induces CIP alignment and chain formation along the field lines, enabling fast self-assembly of a high-aspect-ratio bionic micro-pillar array. Results demonstrate that TRBIS responds to photo, thermal, and magnetic stimuli individually and enables coordinated multi-stimulus regulation. Importantly, it integrates the complementary merits of the three modes, combining rapid and reversible magnetic actuation, thermally induced shape-memory fixation/retention, and photo-enabled non-contact triggering with localized, high-precision control. This strategy also enhances the structural stability and durability of TRBIS under repeated switching cycles. Ultimately, we demonstrated robust cross-species wetting regulation under coupled photo/thermal/magnetic stimuli, providing a generalizable route toward multi-stimuli-responsive platforms for intelligent microfluidics and micro-manipulation.

Rechargeable magnesium-metal batteries (RMBs) have been regarded as promising candidates for energy storage systems owing to the high volumetric capacity, favorable safety profile, and high crustal abundance of Mg. However, the performance of RMBs is constrained by sluggish Mg2+ diffusivity in the cathode materials, leading to a substantial electrochemically inactive interior volume. Herein, we achieved the fast solid-state diffusion of Mg2+ by constructing an ordered shell-to-core built-in electric field (BEF) via orientated MoS2/MoO2 coaxial heterojunction nanotube arrays, giving rise to high capacity even at low temperatures. Benefiting from the easy transport and deep intercalation depth of Mg2+, the obtained cathode delivered an outstanding rate performance (312 mAh g–1 at 0.05 A g–1 and 115 mAh g–1 at 5 A g–1) and long-term durability with an average fade of 0.0025% per cycle over 4000 cycles. Impressively, a capacity of 150 mAh g–1 was still retained at 0.05 A g–1 even at −20 °C because of the maintained largely promoted Mg2+ diffusivity of 10–10 cm2 s–1 at this low temperature, which is promising but rarely reported for RMBs.

The glycerol electro-oxidation reaction (GEOR) to formate represents an attractive technology for the concurrent production of hydrogen and the valorization of biomass. However, the intricate pathway of GEOR and the high cost associated with noble metal electrocatalysts hinder its progress. Herein, ultrathin CuCoNiW medium-entropy oxide nanosheets (CuCoNiWOx UNS) serve as an effective noble-metal-free catalyst for this transformation. It delivers a high mass activity mass activity of 632.9 mA mgmetal–1, a low potential of 1.0 V vs RHE at 10 mA cm–2, and a formate selectivity of 83.1%, with remarkable stability over 40 h. The high performance is attributed to the distinct roles of each metal within the medium-entropy structure: subsurface W atoms ensure structural stability; Co and Ni sites optimize the adsorption of glycerol and intermediates; and Cu sites promote C–C bond cleavage. The reaction pathway involves the sequential conversion of glycerol to glyceraldehyde, glyceraldehyde to glycolaldehyde/formate, and glycolaldehyde to formate. These findings emphasize the efficacy of implementing medium-entropy structures as a viable strategy for biomass electrooxidation reactions.

MoS2-based catalysts typically confront the critical challenge of balancing high catalytic activity and stability for the hydrogen evolution reaction (HER). This issue remains largely unresolved to date, seriously hindering their practical application. Herein, we develop a feasible molecule fence strategy to address this challenge by confining highly active Ni-doped MoS2 (Ni-MoS2) within a NiS2 fence featuring molecular selectivity. The combined density functional theory (DFT) calculations and in situ spectroscopy measurements reveal that the NiS2 layer as a molecule fence not only enhances the adsorption of H2O molecules but also protects Ni-MoS2 active components from the corrosion by O2 and OH– toxic species, thus greatly inhibiting the leaching of Ni-MoS2 as well as promoting its HER activity. Furthermore, the Ni-MoS2@NiS2-assembled anion exchange membrane water electrolysis (AEMWE) device can achieve a low voltage of 1.85 V to reach a current density of 1000 mA cm–2 and maintains a long-term operation for 1000 h. This study offers insights and valuable guidance for rational construction of electrocatalysts with high activity and stability.
