Background Durable superhydrophobic coatings offer a pleasing visual experience and robust self-cleaning capabilities, providing reliable support for enhancing living quality and industrial safety. In the manufacturing of modern superhydrophobic coatings, especially those derived from natural and renewable biomass materials, abrasion resistance, practicality, and the application performance of various colors have become key considerations. Wood fiber, a natural, abundant and sustainable material, has great potentials in hydrophobic material application due to its low-cost, biodegradation, UV resistance properties. Methods In this study, a biomimetic bird's nest-shaped material with multicolored durable superhydrophobic functions achieved by modifying wood fiber with ZnO nanoparticles and fluorination was developed, which takes the form of powder, flexible film, and solid powder paint. Significant Findings Compared to traditional hydrophobic paints, it can be easily applied to various substrate surfaces with desired colors, including flexible tapes and paper, rigid glass and steel plates, providing a feasible solution for the low-cost, excellent durability, multi-functional, and high-value utilization of superhydrophobic materials.

The microbial reduction of graphene oxide (GO) represents a sustainable approach for producing functional nanomaterials, yet the mechanisms in Gram-positive bacteria remain poorly understood. In this study, Lysinibacillus sphaericus HJ-3 was shown to effectively reduce GO through both direct cytochrome-mediated electron transfer and flavin-dependent shuttling. Whole-genome sequencing revealed complete respiratory chain and flavin biosynthesis pathways, while metabolomic profiling indicated enrichment of riboflavin and aromatic amino acid metabolism under GO stress. qRT-PCR analysis further confirmed the upregulation of key electron transport genes, particularly c-type cytochromes, during GO reduction. Control experiments, including abiotic, heat-killed, and non-reducing Gram-positive strains, verified that the process is a genuine biotic activity requiring metabolic viability. Together, these findings provide multi-omics evidence for the extracellular electron transfer mechanism of GO reduction in L. sphaericus and highlight its adaptive responses to redox stress. Importantly, the study demonstrates that endogenous flavins act as efficient electron shuttles to enhance electron transfer, thereby facilitating the microbial reduction of GO. This work not only deepens the understanding of extracellular electron transfer in Gram-positive bacteria but also underscores the potential of microbial strategies as green and scalable approaches for advanced graphene-based materials.

In this study, a g-C 3 N 4 /MoS 2 composite membrane was successfully fabricated via electrostatic interactions and vacuum-assisted self-assembly. The established heterojunction markedly enhanced charge separation, yielding superior visible-light photocatalytic activity with 95.5% methylene blue degradation in 150 min. The membrane also demonstrated efficient dye separation (70.8% rejection for carmine red; 66.7% for malachite green) and notable antifouling properties, achieving a 74.9% flux recovery after visible-light cleaning. This work presents a synergistic strategy for simultaneous photocatalytic degradation and membrane separation in advanced water treatment.

Effective wound management is crucial for improved outcomes through timely, personalized therapies. Current dressing-based treatments lack dynamic regulation and microenvironment modulation, leading to suboptimal healing. Integrating electrical stimulation therapy with electro-controlled drug delivery promotes skin generation, ensures precise dosing, and accelerates healing. Flexible electronic patches are ideal platforms for these synergistic therapies but face challenges: rigid post-manufacture shapes and sizes limit adaptability to diverse wound geometries, and substrate materials struggle to meet both wound-healing and electronic requirements. This study develops a tailorable, transferable flexible electronic patch with a hexagonal modular design, enabling shape/size customization while maintaining electrical continuity. The water-transfer printing (WTP) technique is used to conveniently transfer conductive chondroitin sulfate (CS) hydrogel (as electrodes and drug reservoirs) and silver circuits onto clinical dressings. This method endows clinical dressings with functionality of electro-controlled drug release and electrical stimulation, simultaneously addressing substrate performance limitations of flexible electronic patches. The patch demonstrates uniform electrical signal transmission, precise electro-responsive drug control in CS hydrogels, and adaptability to wounds of different geometries. It retains electrostimulation and electro-controlled drug delivery performance after cutting, significantly promoting wound healing. This study provides a potential approach to support the advancement of flexible electronics research and clinical translation.

Microfluidic rough-fracture experiments track residual DNAPL morphology, interfacial area, and dissolution. • Interfacial-area scaling depends on residual architecture and dissolution stage. • Interface renewal and hydraulic accessibility jointly control DNAPL dissolution in rough fractures. Residual dense non-aqueous phase liquids (DNAPLs) trapped in fractured rock can sustain groundwater contamination through long-term dissolution. In rough fractures, aperture-field anisotropy controls preferential flow and residual source-zone architecture, causing interfaces of similar geometric area to differ in hydraulic accessibility. However, direct pore-scale evidence remains limited on how residual architecture and hydraulic accessibility jointly control dissolution pathways and interfacial-area-based mass-transfer scaling. Here, microfluidic experiments were used to quantify the co-evolution of residual DNAPL saturation, specific water–DNAPL interfacial area ( a s ), and the image-derived apparent dissolution coefficient ( K app ). Aperture-field anisotropy and displacement history generated pool-dominated (PP), ganglia-dominated (GP), and mixed (MP) residual architectures with distinct dissolution pathways. Across Re = 0.395–6.583, flow rate altered dissolution kinetics and stage duration, but the dominant architecture-dependent response remained identifiable. PP systems underwent fragmentation-driven interface generation followed by contraction-dominated depletion, GP systems were dominated by ganglia contraction, and MP systems exhibited spatially sequential dissolution. GP trajectories generally occupied higher K app ranges, whereas MP trajectories occupied lower ranges. Aperture-field anisotropy modified residual morphology, pool elongation, interfacial-area evolution, and fragmentation persistence, indicating a pathway-level control on dissolution behavior. The proportional K app − a s relationship did not hold universally: fragmentation-dominated stages produced scattered relationships, whereas contraction-dominated stages yielded more coherent but architecture-dependent responses. During GP Stage III, K app decreased more rapidly than total a s , indicating reduced apparent transfer efficiency per unit geometric interface. These findings show that predictive models of DNAPL dissolution in fractured media should account for residual source-zone architecture, aperture-field anisotropy, dissolution stage, and the evolving hydraulic effectiveness of the water–DNAPL interface.

Food industry wastewater containing synthetic dyes threatens ecological safety and human health. Therefore, efficient and environmentally friendly adsorbents that can remove synthetic food dyes from wastewater are urgently needed. In this work, a self-nitrogen-doped biochar (GSNBC), used for adsorption of food dyes including carmine and tartrazine, was facilely prepared by employing ginger straw waste as the carbon precursor and NaHCO3as a mild and relatively benign pore-forming agent via one-step pyrolysis. The as-prepared GSNBC featured well-developed porous structures, a specific surface area of 1712.52 m2g−1, and rich oxygen- and nitrogen-containing functional surface groups. Particularly, GSNBC performed ultrafast adsorption, with approximately 90% of the equilibrium capacity within 1 min (600.13 mg g−1and 580.24 mg g−1for carmine and tartrazine, respectively), and reached adsorption equilibrium at about 10 min. In addition, it exhibited excellent regenerability. The adsorption kinetics and isotherms fit well with pseudo-second-order and Langmuir models. DFT calculations indicated that π–π stacking and hydrogen bonding were mainly responsible for the adsorption. This study presents not only a promising and efficient adsorbent for the remediation of dye-laden food industry wastewater but also a sustainable route for the resource utilization of ginger straw waste.

Background Previous research has indicated that chenodeoxycholic acid (CDCA) plays a significant role in intestinal motility and is implicated in some gastrointestinal (GI) disorders. However, the impact of CDCA on defecation patterns in infants, particularly those who are breastfed, remains unclear. This study explored the relationship between CDCA and defecation frequency in breastfed infants, focusing on the underlying mechanisms. Methods We measured CDCA levels in stool samples of infants with varying defecation frequencies using metabolomics, along with studies to explore the impact of CDCA on murine colonic transit and with in vitro cellular studies to elucidate the underlying physiological mechanisms. Results In our murine model, CDCA treatment increased GI transit distance, enhanced fecal water content, and reduced transit time, without causing significant colonic damage. Additionally, CDCA treatment enhanced 5-hydroxytryptamine (5-HT) secretion and upregulated signaling molecules such as tryptophan hydroxylase 1 (Tph1), G protein-coupled bile acid receptor 1 (TGR5), and transient receptor potential ankyrin 1 (TRPA1). Selective inhibition of these pathways suppressed 5-HT secretion and normalized intestinal motility parameters, confirming their mechanistic role. Moreover, CDCA treatment of rat insulinoma-derived RIN-14B cells also resulted in increased 5-HT secretion. Conclusions These findings reveal that CDCA significantly correlates with defecation frequency in breastfed infants and likely influences intestinal motility through the TGR5/TRPA1-5-HT signaling axis.

Because tissue responses to implants determine the success or failure of tissue engineering products, fibroin/sericin-based scaffolds including bionic silk scaffolds, native silk fibers, fibroin fibers, and regenerated fibroin have been fabricated, and their biocompatibility was investigated. Fibroin/sericin-based scaffolds were characterized by scanning electron microscopy (SEM) and X-ray diffraction (XRD). Bionic silk scaffolds were beneficial to silk fiber formation through self-assembly. Histological and immunofluorescent staining analysis demonstrated that bionic silk scaffolds did not show significant inflammatory responses. Immunization analysis showed that soluble fibroin and sericin did not show obvious immunogenicity. This work supplied an effective approach to design fibroin/sericin-based scaffolds for tissue engineering and drug delivery.

Colorant tartrazine is widely used in the food industry, but its long-term and excessive consumption is harmful to human health. Therefore, it is necessary to establish a sensitive detection method for tartrazine. Blue fluorescent carbon dots with L-arginine and o-phenylenediamine as precursors, namely L-Arg/oPD-CDs, were prepared via the hydrothermal method. Then, L-Arg/oPD-CDs were further purified by dialysis, thin layer chromatography and column chromatography. A dual-mode nanosensor based on fluorescent and UV absorption was successfully developed. Excellent linear ranges of 0–5 μM and 10–50 μM were obtained with a low detection limit of 42.3 nM based on fluorescence. A good linear range of 0–50 μM was obtained with a low detection limit of 130.15 nM based on UV absorption. The quenching mechanism of tartrazine towards L-Arg/oPD-CDs fluorescence was the inner filter effect. In addition, a dual-mode nanosensor was used for tartrazine determination in millet, maize flour, carbonated drink, and sugar samples. This study provides new insight into the detection of tartrazine by applying a dual-mode nanosensor.

The novel binary metal oxide cerium molybdate (Ce 2 Mo 3 O 13 ) as a promising strategy can be combined with MWCNTs for the development of ultrasensitive sensors. Herein, a pod-like Ce 2 Mo 3 O 13 was prepared, characterized, and used to construct a molecularly imprinted sensor (MIPs) for detection of ponceau 4 R as low as to nanomolar concentration. The results demonstrate that the electrochemical response at the specific hybridized electrode of MIPs/Ce 2 Mo 3 O 13 -MWCNTs/GCE is stronger than non-molecularly imprinted ones (NIPs). It indicates a synergistic effect resulting from the hybridized Ce 2 Mo 3 O 13 -MWCNTs combination and modification to the electrode. Under optimal conditions, the calibration curve is in the range of 10 nmol L −1 to 1 μmol L −1 , with a limit of detection of 7 nmol L −1 for ponceau 4 R determination. The excellent sensitivity, reproducibility, and selectivity of the new sensor provide an accurate and facile avenue for ultrasensitive ponceau 4 R detection in different samples.

Surface-enhanced Raman scattering (SERS) has been explored and acts as a practical analytical detection approach. However, constructing highly sensitive SERS substrates usually involves expensive materials and tedious preparation processes, and SERS substrates often cannot be reused. Herein, direct hetero-integration of three-dimensional graphene (3D-graphene) with silicon-on-insulator (SOI) substrate can be utilized as a highly stable, ultra-sensitive, low cost and reusable SERS substrates through plasma-assisted chemical vapor deposition (PACVD). The novel nanocavity construction of the 3D-graphene combines with the optical cavity system of the SOI to improve the interaction between the incident light and 3D-graphene, which is a model for doubly-reinforced Raman scattering. These properties enhance electronic interactions between 3D-graphene, target molecules, and SOI substrates, thereon improving chemical/charge transfer effects in heterojunctions. The as-designed 3D-graphene/SOI heterojunction has detection limits of ∼10−10 M for rhodamine B (RB) and rhodamine 6G (R6G), and the detection limit for crystalline violet (CRV) is ∼10−8 M, which is better than the existing reported graphene-based SERS. Our study confirms the efficient carrier transfer mechanism in the 3D-graphene/SOI heterojunction and enhances the chemical/charge transfer mechanism of SERS by double-enhanced high-light absorption. In addition, erythrosine B (EB) and carmine, considered harmful pigment additives in fruit-flavored beverages, were selected as the detection targets with a detection limit of about 10−9 M and 10−8 M, suggesting that 3D-graphene/SOI heterojunction-based SERS can be applied in the food safety field.

An ability to integrate adaptive coloration and tissue-like compositions, structures, as well as mechanical properties, and so forth into a material remains elusive. To address this problem, this work presents a solution whereby these features were integrated into a proteinic artificial skin through biomimetic design. In this artificial skin, silk fibroin was used to mimic the structural framework of the cytoskeleton due to its unique molecular network structure and outstanding and tunable mechanical properties. Meanwhile, a thermochromic filamentous network consisting of C25-GAGAGAGY amphiphilic peptides was designed to mimic the functional tracks in the cytoskeleton, enabling its temperature-adaptive coloration ability. The interconnected linkage between the structural frame and functional units makes this artificial skin have stable structures, mechanical properties, and functions. The whole protein composition also makes this artificial skin essentially different from other existing color-tunable artificial skins, which are a combination of organic and inorganic compounds. Furthermore, because the protein composition is compatible with a range of dyes, the chromatic gamut of adaptive coloration of the developed artificial skin can be further expanded by color fusion. With the further inclusion of other functional units, such as photothermal and magnetothermal nanoparticles, the thermochromism of the artificial skin could be realized through sun exposure and alternating magnetic field modulation. With this diversity in color change pathways and stimulation mode, as well as the environmental friendliness of the material used, these artificial proteinic skins have promising applications as sensors in physiological monitoring, food preservation, and anti-counterfeiting.
