The efficient separation of emulsified oily wastewater was of significant practical importance. However, it was hindered by factors such as low separation flux and severe membrane fouling, making the separation process highly challenging. Inspired by the in-situ nanocomposite strategy mediated by bionic mussel adhesion, this study used oxidants to induce rapid deposition of dopamine (DA) and fulvic acid (FA) on the polyvinylidene fluoride (PVDF). Combined with in-situ growth technology, ZIF-8 nanoparticles were anchored on the coating surface to construct a PVDF-based composite membrane with heterogeneous wettability structure was constructed which were composed of lipophilic ZIF-8 protrusions, hydrophilic layer, and PVDF basement membrane. In the process of separating oil-bearing lotion, the raised ZIF-8 helps to capture and collect oil droplets, and works in synergy with the screening effect of the hydrophilic layer. The demulsification capability was enhanced by the unbalanced force derived from the wettability discrepancy between the protrusions and the substrate, thus enabling efficient separation of emulsions. The optimized composite membrane efficiently separates light/heavy emulsions, with a rejection rate exceeding 99.4 %. The n-hexane-in-water emulsion maintained a high recovery flux ( FRR ) of 92.3 % after 30 cycles. Molecular dynamics simulations confirm that the membrane's hydrophobic/hydrophilic architecture actively promotes emulsion demulsification and oil droplet separation. This study provides precious view into the design of emulsion separation membranes and advances in separation technologies.

Swietenia macrophylla King, a medicine food homology, has garnered attention for the hypoglycemic and hypolipidemic activities of its fruit in the improvement of metabolic dysfunction-associated steatotic liver disease (MASLD), yet the glucolipid regulating properties of its leaf remains unexplored. The study sought to examine the pharmacological mechanisms underlying the lipid-lowering effects of Swietenia macrophylla King leaf extract (SLE) and its active constituent senegalension B (one of 31 limonoids in SLE). Glucolipid regulation by SLE and active constituent was evaluated through cellular triglyceride content and peripheral glucose levels in primary mouse hepatocytes (PMHs), SLE dose-dependently reduced lipid accumulation in the range of 23.65±3.41% to 37.39±2.50%, validated by Oil Red O staining. Network pharmacology and RNA sequencing identified SREBP-1c/FASN axis as the key mechanism by which SLE improved lipid accumulation in PMHs, consistent with senegalension B. RT-qPCR and Western blot showed that SLE (40 μg/mL) decreased the lipid synthesis regulator SREBP-1c mRNA and protein levels by 60.69±1.69% and 48.07±11.83%, respectively, whereas senegalension B (40 μM) achieved 55.42 ±2.29% and 34.34±8.49% inhibition. Dual-luciferase reporter assays revealed that senegalension B suppressed SREBP-1c promoter activity in Hep G2 cells. Molecular docking suggested a potential interaction with SREBP1, consistent with molecular dynamics simulation comparing binding affinity and stability with LXRα, indicating that senegalension B may exert lipid-lowering activity by targeting key proteins involved in lipid synthesis, such as SREBP-1c. This study elucidated the mechanisms and potential of SLE and senegalension B in regulating MASLD through in vitro investigation, expanded the utilization of Swietenia macrophylla King resources, and provided a candidate plant-derived compound for dietary therapy.

Emulsified oils and dye contaminants already pose a huge threat to global ecosystems and human health. It is a significant research topic to develop efficient, rapid, versatile methods for emulsion separation and dye adsorption. The membrane material modified with common methods only modified the outer surface of the membrane, while the interior is hardly fully decorated. In this investigation, a solvent exchange method was used to in situ grow nanoparticles in the interior of a porous sponge. These nanoparticles were obtained with polyethyleneimine, gallic acid, and tannic acid via Michael addition and Schiff base reaction. The prepared nanoparticle-coated sponges provided efficient separation of dyes, emulsions, and complex contaminants. The separation efficiency of the dye reached 99.49%, and the separation efficiency of the emulsion was as high as 99.87% with a flux of 11140.3 L m −2 h −1 . Furthermore, the maximum adsorption capacity reached 486.8 mg g −1 for cationic dyes and 182.1 mg g −1 for anionic dyes. More importantly, the nanoparticles were highly robust on the surface of the porous sponge, and the modified sponge could have long-term applications in hazardous environments. Overall, it is envisioned that the nanoparticles-modified porous sponge exhibited considerable potential for emulsion and dye wastewater treatment.

The development of anti-fouling membrane materials was inspired by marine mussel organisms, as membrane surfaces with adhesive materials has enhanced anti-fouling properties. A polycaprolactone (PCL) substrate with superhydrophobic properties was prepared using electrospinning technology. Hydrophilic silane coupling agents KH560 and TEOS were modified on the substrate through the biomimetic adhesion of tannic acid. Surface superhydrophilic/underwater superoleophobic PCL membranes were prepared by a simple and low-cost preparation method, and the surface modification mechanism was further analyzed. The results demonstrated that the modified WCA decreased ultimately to 0°. The oil–water separation efficiency of the prepared superhydrophilic/underwater superhydrophobic PCL composite membrane was 99.94 % and 98 %, respectively, tested using standard simulated oil and crude oil emulsions, with fluxes of 6000 L m −2 h −1 , 5850 L m −2 h −1 , demonstrating effective separation of various oil–water emulsions. The results revealed changes of crystal morphology in membrane materials before and after modification, as well as membrane’s thermal stability under high temperatures. The mechanical properties of the composite membrane were assessed using a tensile tester. Changes in surface morphology and roughness were investigated using SEM and AFM. After 20 times oil–water separations, the membrane demonstrated a consistent over 99 % separation efficiency. which demonstrated that the membrane exhibits excellent stability and resistance to oil.

In the wake of recurring oil spills causing devastating environmental and ecological damage, there is an urgent need for efficient oil spill remediation strategies. Conventional absorbents are often ineffective in harsh environments and struggle with the recovery of high-viscosity crude oil at room temperature. Although photothermal absorbents can greatly improve the fluidity of crude oil, their practical applications are still limited due to complicated preparation processes, hazardous fluorinated reagents, and secondary pollution. This study introduces a facile, one-step dip-coating method to develop a photothermal superhydrophobic melamine sponge (MS), incorporating a fluorine-free suspension of polydimethylsiloxane (PDMS), siloxane-containing acrylate copolymers (SAC), and polydopamine nanoparticles (PDA NPs). The resulting PDMS/SAC-PDA@MS shows an exceptional water contact angle (WCA) and significant self-cleaning abilities due to its superhydrophobicity. With superior mechanical and chemical durability, the sponge achieves remarkable oil absorption (up to 102.6 times its weight) and efficient oil/water separation. Crucially, under solar irradiation, the sponge’s surface temperature reaches 87.6 °C, effectively reducing oil viscosity and enabling rapid cleanup of oil spills and active deicing. This study presents a green, economical approach to synthesizing photothermal superhydrophobic adsorbents with potential applications in environmental cleanup and active deicing.

Fat reduction due to heating or cooking is an important issue in a healthy diet. In the current study, pork subcutaneous back fat was treated via microwave heating (MH) within 10—90 s and roasting - steam heating (RSH) within 2—30 min and their dynamic changes of individual adipocytes were explored by using vesicles as a bio-membrane model. The result showed that MH and RSH significantly increased fat loss ( P < 0.05), with the maximum losses being 74.1 % and 65.6 %, respectively. The mechanical strength of connective tissue decreased and then increased slightly. The microstructure demonstrated that MH and RSH treatments facilitated a large outflow of fat, showing that the particle size of the vesicle and individual adipocytes increased and then decreased. It is thus feasible to study the dynamic changes of individual adipocytes in regulating fat reduction using cell membrane simulation.

Multifunctional adsorbents are significant for the treatment of water-soluble dyes in contaminated aquatic systems and oily dyes in colored organic effluents. However, the existing adsorbent for both water-soluble and oil-soluble dyes is rare and the cleanup effect is not ideal. In this study, alginic acid carbon aerogel (AACA) as an effective wide-spectrum adsorbent was prepared through wet-spinning, ion-exchanging, drying, and high-temperature carbonization. AACA obtained a specific surface area of 1046.0 m 2 g −1 and a mean pore size of 2.82 nm. The adsorption capacities of AACA for methylene blue (cationic dye), methyl orange (anion dye), and oil red O (oil-soluble dye) were 493.5, 389.5, and 244.2 mg g −1 , respectively, which were improved in comparison with those of previously reported calcium alginate and ferric alginate carbon aerogels. The adsorption kinetics of AACA for the three dyes were fit for the pseudo-second-order kinetic model and the adsorption isotherms could be explained by the Langmuir model. ACCA revealed good adsorption performance for other eleven different sorts of dyes and binary dye systems. The adsorption mechanism was mainly confirmed to be π–π interactions.

Self-cleaning coatings have been garnering significant attention for their ability to reduce surface pollution by repelling liquids. However, creating transparent self-cleaning coatings that effectively repel ultralow surface tension liquids in harsh environments, like extremely high or low temperature environments, remains a challenge. Here, a transparent omniphobic coating (PMAPOSS-co-PFMA) is reported to achieve the repellency of droplets with surface tensions down to 15.5 mN·m −1 (n-pentane), even at temperatures up to 160 °C and down to −70 °C. The coating is engineered by grafting fluoropolymer with fluoroalkyl side chains onto the rigid polyhedral oligomeric silsesquioxane framework. The fluoroalkyl side chains tend to crystallize on the coating's surface, resulting in its low surface tension (measured at 9.39 mN·m −1 ). The incorporation of the robust POSS significantly enhances the coating's chemical, mechanical, and thermal stability. Moreover, with low roughness (R a = 1 nm), the coating has a light transmittance of 90.5 %, surpassing untreated glass by 3.2 %. Heated at 80 °C, the migration of the long-fluorinated polymer chains within the PMAPOSS-co-PFMA coating enables its self-healing properties upon damage. These results provide a new perspective to develop versatile self-cleaning omniphobic coatings suitable for practical applications in extreme environments, such as asphalt transport pipes operating in high-temperature conditions.

Porous membranes with superhydrophilicity and underwater superoleophobicity have attracted considerable attention for efficient oil/water emulsion separation. However, such membranes fail to remediate severe oil contamination in long-term applications and exhibit a serious water flux decline. Herein, a universal combination strategy integrating the high coverage of a mussel-inspired sticky interlayer and a double rigid cellulose nanofiber-amorphous calcium carbonate (CNF-ACC) composite outer layer is proposed to prepare a superhydrophilic coating surface with superior anti-oil-fouling properties on diverse substrates. The introduction of the mussel-inspired interlayer not only provides a stable and complete coverage interface but also offers an anchor to fix the outstanding hydration of the outer CNF-ACC composite layer. The high-coverage and double rigid superior hydration CNF-ACC layer provides excellent anti-oil-fouling characteristics, irrespective of the type of oil, under various conditions, such as water-prewetted or oil-fouled environments. Owing to its superior anti-oil-fouling property, the coating-modified membrane shows efficient and long-term separation of diverse oil/water emulsions without significant flux decline and with a flux recovery ratio of nearly 100%. In addition, this coating exhibits antifogging and high transparency, which may show promising applications in diverse optical devices.

Periodontal bone defects, primarily caused by periodontitis, are highly prevalent in clinical settings and manifest as bone fenestration, dehiscence, or attachment loss, presenting a significant challenge to oral health. In regenerative medicine, harnessing developmental principles for tissue repair offers promising therapeutic potential. Of particular interest is the condensation of progenitor cells, an essential event in organogenesis that has inspired clinically effective cell aggregation approaches in dental regeneration. However, the precise cellular coordination mechanisms during condensation and regeneration remain elusive. Here, taking the tooth as a model organ, we employed single-cell RNA sequencing to dissect the cellular composition and heterogeneity of human dental follicle and dental papilla, revealing a distinct Platelet-derived growth factor receptor alpha (PDGFRA) mesenchymal stem/stromal cell (MSC) population with remarkable odontogenic potential. Interestingly, a reciprocal paracrine interaction between PDGFRA + dental follicle stem cells (DFSCs) and CD31 + Endomucin + endothelial cells (ECs) was mediated by Vascular endothelial growth factor A (VEGFA) and Platelet-derived growth factor subunit BB (PDGFBB). This crosstalk not only maintains the functionality of PDGFRA + DFSCs but also drives specialized angiogenesis. In vivo periodontal bone regeneration experiments further reveal that communication between PDGFRA + DFSC aggregates and recipient ECs is essential for effective angiogenic-osteogenic coupling and rapid tissue repair. Collectively, our results unravel the importance of MSC-EC crosstalk mediated by the VEGFA and PDGFBB-PDGFRA reciprocal signaling in orchestrating angiogenesis and osteogenesis. These findings not only establish a framework for deciphering and promoting periodontal bone regeneration in potential clinical applications but also offer insights for future therapeutic strategies in dental or broader regenerative medicine.

Aerogels are widely used in environmental remediation, but their application is hindered by brittleness, limited oil absorption and poor separation of viscous crude oil. In this study, a multifunctional superhydrophobic aerogel with electrothermal and photothermal effects was prepared from bacterial cellulose (BC), methyltrimethoxysilane (MTMS), and hydroxylated carbon nanotubes (HCNT) by soft-hard synergistic and directed freezing. The prepared aerogel exhibited an oriented layered porous structure with excellent compressibility and oil retention capacity. The aerogel maintained 250 cycles of 25 % strain compression without structural degradation. Because of the presence of Si-CH 3 , the aerogel maintained a water contact angle above 153° across pH 1–13 and retained superhydrophobicity (WCA˃150°) even after severe abrasion. The prepared aerogel exhibited excellent absorption capacities for various organic solvents and oils, ranging from 45 g/g for n-hexane to 112 g/g for dichloromethane, and retained 96 % of dichloromethane through capillary locking. The well-dispersed HCNT enabled efficient photothermal (117.7 °C) and electrothermal (126.7 °C) conversion, facilitating rapid and continuous separation of crude oil/water mixtures at high fluxes (4.47 × 10 4 kg·m −3 ·h −1 and 8.15 × 10 4 kg·m −3 ·h −1 under photothermal and electrothermal conditions, respectively). This material holds great potential for practical application in high efficiency oil-water separation, particularly in challenging conditions involving viscous crude oil.

In recent years, the growing demand for sustainable and clean-label health foods has made mild processing a key approach to obtaining less denatured and high-quality plant-based protein ingredients. This study compared soy protein isolate (SPI) obtained via salt extraction (S-SPI) with SPI obtained via the conventional alkali-solubilization and acid-precipitation method (A-SPI), to investigate the impact of protein aggregation structure on the formation of SPI/gum arabic (GA) complex coacervation. Native-PAGE and SDS-PAGE results revealed that mild extraction processes lead to the enrichment of glycinin in SPI. The electrokinetic interactions of S-SPI/GA coacervates were analyzed using soft particle theory, linking the charged properties of biopolymers to their complex structures. Dynamic wetting behavior results showed that the low interfacial tension of S-SPI/GA coacervates facilitated wetting at the oil–water interface and the formation of a continuous layer. This study proposed a novel approach to developing low-denaturation, natural plant proteins and provided new insights into the formation mechanisms of plant protein-based complex coacervates.
