Enhancing hydrophobic bioactives' bioaccessibility remains challenging in functional foods due to instability and insufficient controlled-release ability in conventional protein-polysaccharide carriers. We pioneer a new interaction model by covalently grafting corn stover cellulose nanofibers (CNF) with Zein using N-(3-dimethylaminopropyl)-N′-ethyl carbodiimide hydrochloride (EDC) and N-hydroxysuccinimide (NHS), creating conjugates with gradient grafting degrees (CNF/Zein 0.5, CNF/Zein 1, and CNF/Zein 2). Excitingly, compared to the non-covalent complex (CNF-Zein), conjugates exhibited a stable network-like microstructure, lower crystallinity, and enhanced thermal stability. Furthermore, the conjugates exhibited excellent amphiphilicity, forming denser and more stable emulsions. Confocal laser scanning microscope (CLSM) revealed a dual stabilization mechanism of “interface adsorption-network encapsulation”. Additionally, CNF/Zein-stabilized emulsions demonstrated controlled quercetin release and improved bioaccessibility during in vitro digestion tests, with the highest grafted CNF/Zein 2 showing 43.65 % bioaccessibility. This study first demonstrates the effectiveness of the EDC/NHS technique in alcohol-solution systems, providing novel strategies for conjugate design and lipophilic nutraceutical delivery.

Aqueous zinc-ion batteries (AZIBs) based on hydrogel electrolytes are considered promising flexible power supplies owing to their intrinsic safety, competent volumetric energy density, and eco-friendliness. However, severe mechanical deterioration of the hydrogel electrolytes caused by insufficient inter-component contact, zinc (Zn) dendrites, and freezing prevents their commercialization. Herein, it is found that, by doping a trace of Fe 3+ ions to afford Fe 3+ -carboxylate supramolecular interaction, the practicality of an archetypal cellulose nanofiber-reinforced hydrogel electrolyte is significantly improved in a couple of aspects, including three and eight times increase in tensile strength and toughness without loss of ion conducting ability (up to 32 mS cm −1 ) and being room-temperature self-healable and strongly adhesive to various battery components. Together with the use of an anti-freezing mixed Zn salt, the resulting hydrogel electrolyte is able to deliver ultrahigh Zn cycling reversibility (averaging 99.4%), the great cyclability of AZIBs (a high specific capacity of 180 mAh g −1 and capacity retention of 81%), and render the batteries operable under severe abuse conditions of 180° folding, exposure to liquid nitrogen, and cutting–rehealing cycles. This work unlocks the enormous potential of Fe 3+ -carboxylate chemistry in the development of self-healable, anti-freezing, and extreme-environment-adaptable gel electrolytes for flexible energy storage devices.

To address the challenge of achieving simultaneous pollutant removal and real-time monitoring in water remediation, Z-scheme Cu 2 O/g-C 3 N 4 /Ag heterostructures with integrated functionalities for synergistic adsorption, photocatalytic degradation, and surface-enhanced Raman scattering (SERS) detection were developed—hereafter referred to as APS-Hs (adsorption–photocatalysis–SERS heterostructures). Particular emphasis was placed on the Cu 2 O/g-C 3 N 4 /Ag-1.5 APS-Hs, incorporating an optimized 1.5 wt% Ag loading. Optical and electrochemical tests demonstrated that the Cu 2 O/g-C 3 N 4 /Ag-1.5 APS-Hs significantly enhanced charge separation efficiency and reduced charge transfer resistance. Under visible-light irradiation, the Cu 2 O/g-C 3 N 4 /Ag-1.5 APS-Hs attained a removal efficiency of 98.1 % for methyl orange (MO) within 45 min and sustained an efficiency of 84.0 % after three consecutive cycles. XRD and SEM analyses conducted before and after photocatalytic cycling confirmed the composite's outstanding structural and morphological stability. Notably, the Cu 2 O/g-C 3 N 4 /Ag-1.5 APS-Hs demonstrated the highest adsorption capacity (21.34 mg/g) among all samples. Zeta potential measurements revealed a surface charge reversal from + 22.35 mV to −10.29 mV, indicative of strong electrostatic interactions with anionic pollutants. Pseudo-second-order (PSO) kinetic modeling (R 2 =0.971) further established physisorption as the dominant mechanism. Radical trapping experiments verified that the enhanced photocatalytic performance originates from the Z-scheme charge transfer pathway. Additionally, the Cu 2 O/g-C 3 N 4 /Ag-1.5 APS-Hs substrate achieved a SERS enhancement factor of 3.1 × 10 6 and a broadband self-cleaning capability, underscoring its potential for integrated environmental remediation and sensing applications.

The integration of broadband sound absorption with environmental sustainability remains a key challenge in advanced material design. In this work, an innovative 3D-printed cellulose nanofibril (CNF) architecture with a customizable hierarchical “hole-cavity unity” structure was proposed for highly efficient sound absorption. This multi-scale structural design strategy synergistically coupled the perforated-panel acoustic principles with nanoscale viscous dissipation mechanisms. By leveraging the shear-thinning behavior of CNF inks and the precision control of direct ink writing, the sub-millimeter periodic pore arrays were embedded within the continuous nanofibrous network, enabling programmable structural tunability across multiple pore scales. Systematic regulation of infill ratio and sample thickness yielded high sound absorption coefficients (>0.7) over an ultra-broad frequency range of 1.2–6.3 kHz. Combined with low shrinkage, structural customizability, low density, and rapid environmental degradability, the fully bio-based 3D-printed CNF architectures are expected to offer a promising and sustainable solution for developing next-generation acoustic materials for noise control applications.

Natural seawater contains abundant halide ions that remain largely untapped, while peracetic acid often requires activation to enhance its oxidative properties. The interaction mechanisms between these components have not been thoroughly investigated. This study investigated the activation effect of high concentrations of Cl − and Br⁻ coexisting in seawater on PAA by adding PAA to seawater. Quenching experiments, along with Electron Paramagnetic Resonance (EPR) spectroscopy and UPLC-TQ-MS, were conducted to determine the reaction mechanism and degradation process of SMX. Seawater systems containing 35 ‰ salinity or Br − -PAA systems (0.5 mM Br − ) degraded 100 % SMX within 10 min or 12 min, respectively ( k obs =0.4873 min⁻ 1 or 0.3581 min⁻ 1 ). While the Cl − -PAA system, though slower, still degraded 97.7 % within 180 min (300 mM Cl − , k obs =0.0173 min⁻ 1 ). SMX degradation rates remained above 95 % across the pH range of 3–9, with optimal performance at pH= 3. However, the presence of HA inhibited SMX degradation efficiency by over 40 %. Results indicate that SMX degradation efficiency correlates positively with Cl⁻/Br⁻ content and PAA concentration. The superior removal efficiency stems from activated PAA not only generating HOCl and HOBr via oxygen atom transfer but also further producing 1 O 2 , which dominates the non-selective degradation process. This approach adapts to a wide pH range but is consumed by coexisting HA. The superiority of the Br − -PAA system over Cl − -PAA stems from the strong oxidizing power of HOBr. The oxidation pathways include halogenation, bond cleavage, and hydroxylation. ECOSAR predictions indicated that most transformation products exhibited higher toxicity than the parent SMX compound.

Porous membranes have been fabricated and modified for the separation and purification of wastewater. Although they always suffer from fouling caused by various materials such as oils, dyes, and antibiotics. It is difficult to deal with the boring membrane fouling by one antifouling strategy including hydrophilicity/underwater superoleophobicity. In this work, a synergistic antifouling mechanism combining low oil adhesive underwater superoleophobicity and excellent persulfate advanced oxidation processes (PS-AOPs) performances was developed by facilely loading ZIF-67 catalysts on polypropylene (PP) membranes. The as-prepared composite membranes have stable underwater superoleophobicity and low oil adhesion, which can efficiently separate oil from oil-in-water emulsion and prevent oil adhesion. Moreover, the ZIF-67 catalysts on the composite membranes have excellent degradation performances against various foulants such as methylene blue (MB), tetracycline (TC), and levofloxacin (LVFX), which endow the composite membrane with enhanced antifouling properties during the separation of an oil-in-water emulsion containing MB, TC, and LVFX. The synergistic antifouling mechanism of low oil adhesive underwater superoleophobicity and advanced PS-AOPs provides a facile and efficient strategy for improving the antifouling of the porous membranes in real wastewater purification.
