In this study, an innovative multi-scale research framework integrating molecular dynamics (MD) simulations, machine learning (ML) prediction, and experimental validation was established to systematically elucidate the mechanism by which polyvinylpyrrolidone (PVP) regulates the performance and structure-property relationship of phenolphthalein-based polyether ether ketone/polyethyleneimine (PEEKWC/PEI) ultrafiltration membranes. MD simulations further revealed at the atomic scale that PVP forms a hydrogen-bonding network with the membrane matrix via the carbonyl oxygen of the pyrrolidone ring, thereby significantly enhancing interfacial compatibility. Its flexible chain intercalation can increase the free volume of the membrane. However, excessive addition induces local aggregation and entanglement of molecular chains, hindering water molecule diffusion, resulting in a decrease in diffusion coefficient from 0.115 Ų/ps to 0.082 Ų/ps. The ML model accurately reproduced the decreasing trend of water flux with the increase of PVP content. Combined with SHAP analysis to quantify the influence weight of each factor, it was clarified that operating pressure and surface roughness are the dominant factors, and the global optimal PVP addition amount was identified. Experimental validation showed that the PVP-K90 modified membrane exhibits the best comprehensive performance, with a pure water flux of up to 3162.1 L·m -2 ·h -1 , a Congo Red (CR) rejection rate of 95.3%, and a flux recovery rate (FRR) of 88.9%, demonstrating excellent antifouling performance. The PVP-K120 modified membrane shows better dye rejection effect in high-salt environments, with a rejection rate exceeding 87%. This study moves beyond the traditional trial-and-error approach, reveals the microscopic essence of additive effects through multi-scale correlation analysis, not only successfully prepares high-performance ultrafiltration membranes, but also provides a replicable innovative research paradigm for the directed design and performance optimization of separation membranes.

Sound-absorbing materials prepared with plant fibers have received extensive attention and research since noise is an urgent environmental problem that needs to be solved; however, there is still room for improvement in the sound absorption performance and flame retardancy of these materials. This study carried out functional modification on plant fiber, flame-retardant plant fiber (FrSF), and investigated their effects on the sound absorption and flame retardancy properties of biomass sound-absorbing composite (BSC). When the addition of FrSF was 30%, the maximum sound absorption coefficient (α max ) of the BSC using FrSF was 0.97 at 1530 Hz, and the noise reduction coefficient (NRC) was 0.40. Meanwhile, FrSF could improve the BSC’s flame-retardant performance with less addition of flame retardant. The limiting oxygen index (LOI) of BSC using FrSF was 29.9%, and the total heat release (THR) decreased 57.62% compare with the BSC using E-glass fiber. This work has made practical contributions to the functional modification of plant fibers and the development of plant fiber-based functional materials. Graphical abstract

Epoxy resin (EP) composites with high thermal conductivity are critically important for effective thermal management in modern electronics. However, their development is often hindered by the intrinsically low thermal conductivity of epoxy. In this study, a vertically aligned, neuron-mimetic three-dimensional graphene nanoribbon–carbon nanotube/carbon (GNR–CNT/C) foam was fabricated through gel compression and carbonization of a GNR–CNT/carboxymethyl chitosan (CMCS) hybrid aerogel. This rationally engineered architecture promotes directional phonon transport while substantially reducing interfacial thermal resistance (ITR). After epoxy infiltration, the resulting GNR–CNT/C/EP composite exhibits a high out-plane thermal conductivity of 6.79 W·m⁻ 1 ·K⁻ 1 at a low filler loading of 2.43 vol%, yielding an exceptional thermal conductivity enhancement (TCE) of 1356%. The composite also demonstrates moderate electrical conductivity, with a volume resistivity of 1.04 × 10 3 Ω·cm, and superior mechanical performance—compressive strength reaches 147.26 MPa, a 76% improvement over neat EP. Combined experimental and theoretical analyses reveal that the multidimensionally continuous and oriented heat transfer pathways within the GNR–CNT/C foam effectively mitigate interfacial phonon scattering. This work provides a feasible and scalable route for designing high-performance thermal interface materials with integrated multifunctional attributes for advanced thermal management.

Yellow and green fluorescent sulfur quantum dots (SQDs) were successfully synthesized using cysteamine as a passivator via a one-pot hydrothermal approach. The as-obtained SQDs have uniform particle size and their average particle diameters are 19 nm and 17 nm, respectively. Dynamic light scattering (DLS) tests further validate the concentration-dependent aggregation behavior of the two types of SQDs. Optical property investigations demonstrate that the as-prepared Y-SQDs and G-SQDs exhibit prominent aggregation-induced red-shift emission and reversible fluorescence emission switching behavior regulated by concentration variation. Fluorescence lifetime decay curves are well fitted with a bi-exponential model, and the results reveal that Y-SQDs possess more surface states and defect sites than G-SQDs. The elevation of SQDs concentration aggravates nanoparticle aggregation and shortens the average fluorescence lifetime. These results demonstrate that the fluorescence emission behaviors of Y-SQDs and G-SQDs can be precisely and controllably modulated via concentration regulation. Benefiting from the unique concentration-dependent aggregation-induced red-shift emission characteristics, the obtained SQDs are successfully applied to the preparation of fluorescent inks, fluorescent composite films, and light-emitting diode (LED) devices. Furthermore, application exploration verifies that Y-SQDs and G-SQDs possess excellent application prospects in colorimetric detection, fluorescence sensing, and biological imaging fields.

Ethylene carbonate (EC) and propylene carbonate (PC) are important feedstocks in the production of commercial battery electrolytes and green solvents. However, their conventional industrial synthetic pathways rely heavily on energy-intensive thermocatalytic processes with costly epoxide reactants. Here, we report a class of multifunctional metal-organic framework photocatalysts ( RE-BTTD-AC ) that integrate oxygen (O 2 ) activation, C-H bond activation, photothermal conversion and Lewis acid reactivity. They enable photosynthesis of EC and PC under ambient conditions with a sustainable, cheap and safe method using ethylene (C 2 H 4 )/propylene (C 3 H 6 ), CO 2 , and O 2 . Experimental results combined with theoretical calculations demonstrate that the multifunctional nature of RE-BTTD-AC permits the occurrence of tandem reaction of photoredox and cycloaddition, leading to a relay conversion of C 2 H 4 /C 3 H 6 -to-epoxide-to-EC/PC. The catalytic system exhibits high product yields (EC of 96.02 μmol/g/h with 95% selectivity, PC of 640.03 μmol/g/h with 93% selectivity) in 48 hours and has a long-term production capacity of at least 720 hours.

Transparent, flexible inorganic-organic composites are essential for next-generation adaptive optics, bio-integrated sensing, and reconfigurable photonics. Despite progress in hybrid material design, achieving a material that is simultaneously flexible and transparent across a broad infrared spectrum remains a fundamental challenge. Here, we report a S 60 Se 40 chalcogenide glass designed with a chain-ring dual-network architecture that overcomes this classic limitation. By integrating a dynamic covalent network of physical cross-links with heavy chalcogen elements (S, Se), this dual-network design suppresses multi-phonon absorption and ensures broadband transparency up to 21 μm, combining these optical properties with an ultralow Young’s modulus ( E ≈ 0.0037 GPa), extreme tensile strain (~650%), and high elastic recovery (~80%). The material further exhibits autonomous self-healing and shape-memory behavior at room temperature. We demonstrate its applicability through IR deformable lenses with tunable focal length and real-time aberration correction, showcasing capabilities in adaptive imaging and wavefront control. This work provides a versatile material platform that bridges the gap between glass-like optical performance and polymer-like mechanics, opening avenues for soft infrared photonics and reconfigurable optical systems.

An intelligent relative humidity (RH)-sensing label was developed by integrating a nano-functionalized chitosan/polyvinyl alcohol (PVA) biocomposite with a deep learning (DL) model for real-time monitoring in fresh food packaging. Nanocomposite films were synthesized by incorporating zinc oxide nanoparticles (ZnO-NPs) or titanium dioxide nanoparticles (TiO 2 -NPs) into a chitosan/PVA matrix with methylene blue as an indicator. Comprehensive characterization confirmed successful nanoparticle integration, which formed stable interactions with the polymer network as confirmed by FTIR, XRD, and UV–Vis analyses. The ZnO-NPs samples demonstrated optimal performance, exhibiting superior sensitivity, stability, and a controlled hydrophilic balance (water contact angle: 49.8°) compared to the TiO 2 -NPs samples. The label delivered a distinct colorimetric response (green → blue → black) to elevated RH (> 75% RH). Five DL architectures were evaluated for classifying RH levels from the label’s colorimetric response. The Xception model emerged as the best-performing, demonstrating superior training accuracy (95.2%) and robust generalization ability (95.65% overall accuracy). The practical efficacy of integrating the nano-enhanced label and the Xception DL model was conclusively validated through real-time monitoring of RH within packaged silver carp and apples. This work presents a promising, automated solution for intelligent RH monitoring in fresh food supply chains.

As one of the most popular polysaccharide derivatives with high chiral recognition ability, cellulose tris(3,5-dimethylphenylcarbamate) (CDMPC) has been successfully applied in the enantioseparation of a wide range of racemates for various purposes. However, the derivative is usually synthesized with an amorphous structure, and its effect on enantioseparation ability remains obscure. To obtain a better understanding of the correlation between its structure and enantioseparation ability, in this study, CDMPC derivatives with crystalline and amorphous structures were prepared through carbamoylation followed by anti-solvent precipitation. Their chiral recognition abilities were evaluated using high-performance liquid chromatography (HPLC) with chiral stationary phases (CSPs). Interestingly, the ordered arrangement of the helical polymer chains of CDMPC was effectively induced by the aromatic solvent after derivatization, forming a crystalline derivative ( c-CDMPC ) with a uniform and compact worm-like morphology, whereas the amorphous derivative ( a-CDMPC ) was obtained by regular treatment with a polar alcoholic solvent. The c-CDMPC –based CSP exhibited higher chiral recognition abilities with much shorter retention times for most racemates in this study, compared to the a-CDMPC –based CSP. In particular, flavanone ( Rac-7 ), an important chiral drug with anti-inflammatory, anti-tumor, and cardiovascular protective activities, was even better resolved with higher enantioselectivity on crystalline c-CDMPC than on Chiralcel OD, a commercialized chiral column based on CDMPC. This indicates that the crystalline ordered arrangement played a critical role in the chiral recognition ability of the cellulose derivative.

Cells must continuously sense and respond to environmental changes by translating physical and chemical cues into intracellular signals. However, systematic discovery of genes governing these sensory processes has been limited by the transient nature of signaling events and the low throughput of measurement assays. Here, we present CaRPOOL, a pooled, high‑throughput genetic screening platform that integrates the calcium‑activity recorder CaMPARI2 with CRISPR interference (CRISPRi), enabling stable capture of transient calcium signals for genome‑scale functional screening. Using osmomechanical stimulation as a model, we demonstrate that CaMPARI2 photoconversion faithfully reports stimulus‑dependent calcium responses and supports pooled fluorescence‑activated cell sorting (FACS)–based screening. A CRISPRi library targeting membrane‑associated genes identified both known and previously uncharacterized regulators of osmomechanosensing, including the chemokine receptor CCR7. Mechanistic analyses revealed that CCR7 promotes osmomechanical calcium signaling through a PIEZO1‑dependent Gαs–cAMP–PKA pathway, establishing it as a GPCR regulator of osmomechanical response. Notably, osmotic stress upregulated CCR7 expression in immune cell lines and enhanced osmomechanical responsiveness, suggesting a role in osmomechanical adaptation. Together, these findings introduce a broadly applicable platform for high‑throughput discovery of genes controlling dynamic signaling responses and reveal a GPCR–ion channel crosstalk mechanism in osmomechanotransduction with potential implications for immune cell mechanoadaptation.

The catalytic conversion of lignin derivatives into specific chemicals represents a key pathway for achieving high-valued utilization of biomass. A new Ag–Co 0 /Fe 0.04 Co 0.96 O catalyst was constructed for the selective demethoxylation of vanillic acid derived from lignin depolymerization to produce p-Hydroxybenzoic acid. Compared to Ag–Co 0 /CoO, Fe doping suppressed Co reduction, endowing the Ag–Co 0 /Fe 0.04 Co 0.96 O catalyst with suitable hydrogenation activity and more abundant acidic sites. The hydrogen spillover effect inhibited decarboxylation, dehydroxylation, and benzene ring hydrogenation during the demethoxylation reaction. Oxyphilic Fe species changed the adsorption geometry of vanillic acid from parallel adsorption into twist configuration, avoiding the hydrogenation of benzene ring, and thereby improving the demethoxylation selectivity to p-Hydroxybenzoic acid. By optimizing catalyst preparation and reaction conditions to minimize decarboxylation and over-hydrogenation byproducts, the Ag–Co 0 /Fe 0.04 Co 0.96 O catalyst contributed to a 98.52% conversion of vanillic acid and a 89.62% selectivity to p-Hydroxybenzoic acid under 0.4 MPa H 2 , 0.4 MPa CO 2 at 220 °C for 2 h. This research provided a theoretical foundation and practical guidance for the catalytic demethoxylation of phenolic acids, offering new insights into high-valued utilization pathways for biomass.

Drug-eluting stents are effective for treating cardiovascular disease (CVD), but the procedure can cause mechanical damage to the endothelium, and the released antiproliferative agents delay reendothelialization and impair barrier function, ultimately leading to in-stent restenosis and disruption of vascular homeostasis. Current poststenting therapies, aimed at reducing proliferation and inflammation, often neglect endothelial cell (EC) repair and vascular homeostasis. To address this, we propose the use of a biomimetic nanozyme, HMPB-RAPA@PM&LXW7 (HRPL). Hollow mesoporous Prussian blue (HMPB) nanoparticles serve as carriers for the antiproliferative drug rapamycin (RAPA), which is further modified with a peptide nanoarchitectonics platelet membrane (PM&LXW7). This modification not only targets smooth muscle cells (SMCs) and ECs but also promotes EC repair to accelerate reendothelialization. In response to the acidic inflammatory microenvironment, HRPL releases RAPA to inhibit SMC proliferation and prevent restenosis. Additionally, the nanozyme scavenges reactive oxygen species (ROS), alleviates inflammation, and improves the vascular microenvironment. Both in vivo and in vitro experiments demonstrated that HRPL effectively accelerated reendothelialization, regulated SMC behavior, and reduced inflammation. In conclusion, this peptide nanoarchitectonics biomimetic nanozyme can promote endothelial repair, inhibit neointimal hyperplasia, modulate the inflammatory microenvironment, prevent restenosis, and restore vascular homeostasis, offering a promising approach to reduce complications following clinical stent implantation.

Irreversible electroporation (IRE) is an ablative treatment for pancreatic cancer. It utilizes high-intensity pulsed electric field (PEF) to eliminate cancer cells by irreversibly disrupting cell membranes. However, PEF intensity is distributed unevenly; and cancer cells may survive in regions where it falls below the threshold of complete ablation. We find that iron-base metal organic framework nanoparticles (MOF-Fe) sensitize pancreatic cancer cells to PEF by inducing iron overload and ferroptosis. But their efficacy is diminished by the upregulation of ferritin heavy chain 1 (FTH1), a cellular response to restore iron homeostasis. C20U4V, a proteolysis targeting chimera (PROTAC) derived from arachidonic acid, degrades FTH1 and potentiates MOF-Fe-induced ferroptosis. It is then encapsulated in reactive oxygen species (ROS)-responsive micelles. The resulting M-C20U4V, when combined with MOF-Fe, efficiently induces ferroptosis and boosts PEF ablation efficacy. Therefore, disruption of iron homeostasis represents a potential strategy to lower the risk of tumor recurrence after IRE.
