Novel green-emitting fluorescent microspheres (GreFMPs) were assembled by loading highly luminescent gold nanoclusters (Arg/ATT/AuNCs) on dendritic mesoporous silica nanoparticles (DMSNs) via PEI-mediated electrostatic adsorption. The fluorescence microspheres exhibit excellent monodispersion with average diameters about (254.5 ± 34.6 nm). Compared with free Arg/ATT/AuNCs, the GreFMPs have similar fluorescent properties and biocompatibility but superior environmental tolerance. Subsequently, an immunochromatographic assay based on GreFMPs (GreFMP-ICA) has been successfully developed, which is highly selective toward alpha fetoprotein (AFP) in human serum. Under the optimal parameters, there is a good linear range between 0.5 and 160.0 ng/mL, the limit of detection was found to be about 0.5 ng/mL, and the recovery and relative standard deviation are 81.0 ~ 100.6% and 3.5 ~ 16.6%, respectively. These results manifested that the GreFMPs are beneficial for the rational design of the ICA platform, and the proposed GreFMP-ICA has the potential to screen AFP in clinical applications. Graphical

This study presents a dual-carbon modified LiMn0.6Fe0.4PO4 cathode (LMFP/SWNT/C) through the combined integration of amorphous carbon and single-walled carbon nanotubes (SWNTs). The composite was synthesized via a solvothermal approach followed by carbonization, forming a homogeneous conductive network with enhanced graphitization (IG/ID ratio = 3.24–4.24 versus 0.98–0.99 for LMFP/C). Electrochemical characterization revealed superior performance, including a high discharge capacity of 160.8 mAh g−1 at 0.1C and excellent cycling stability (124.9 mAh g−1 with 92.6% capacity retention after 280 cycles at 1C). In-situ electrochemical impedance spectroscopy (EIS) coupled with distribution of relaxation times (DRT) analysis indicated that the addition of SWNTs could improve the electronic conductivity. These results demonstrate the effectiveness of hybrid carbon architectures for optimizing LMFP cathode materials.

To overcome the critical limitations of conventional phase change composites (PCCs)—including low thermal anisotropy, phase change material (PCM) leakage, and inefficient photo-thermal conversion—we develop a hierarchically engineered PCC by integrating chitosan (CS) aerogel, unidirectionally aligned carbon fibers (CFs), and polyethylene glycol (PEG2000). The CS aerogel matrix suppresses PEG leakage via hydrogen-bonding networks while enabling directional CF alignment, achieving record axial thermal conductivity (6.61 W·m⁻¹·K⁻¹) and exceptional anisotropy (ratio: 11.9). Despite reduced PEG loading with CF content, the composites retain high latent heat (136.6 kJ·kg⁻¹ at 15 wt% CFs) and mechanical robustness. The aligned CF network synergistically enhances broadband solar absorption and directional heat transfer, enabling ultrahigh solar-thermal efficiency (98.5 % at 3.0 sun irradiation). Remarkably, the system exhibits excellent cyclic stability and outdoor operational reliability. This work establishes a scalable paradigm for sustainable thermal energy storage by concurrently resolving the trade-offs among PCM encapsulation, anisotropic thermal management, and photo-thermal conversion.

Water-based inks offer a sustainable alternative to solvent-based systems, yet their performance remains limited by particle sedimentation, poor dispersion, and insufficient film adhesion. In this study, multifunctional hybrid microspheres (SiO 2 -g-R-P) were synthesized by sequentially grafting rosin-derived acrylates and polyethylene glycol (PEG) onto silica particles. The rosin shell enhances compatibility with polyurethane–acrylic binders, while PEG chains provide steric stabilization and hydrophilicity. When incorporated at 1.5 wt% into water-based inks, the modified microspheres markedly improved dispersion stability (ζ potential = −51.6 mV), suppressed sedimentation for over 60 days, and enhanced low-shear viscosity by forming a weak reversible 3D particle network, with the formation of this network demonstrated via oscillatory rheometry (average G″ = 0.35 Pa, average G′ = 7.82 Pa). The resulting inks achieved high-resolution image transfer and strong substrate adhesion (ASTM D3359 rating 2B to 5B) on both paper and steel substrates, outperforming the unmodified formulation. These improvements stem from the synergistic effects of hydrogen bonding, steric hindrance, and particle–matrix interactions at the ink–film interface. This surface-engineering strategy provides a scalable and environmentally friendly approach for developing high-performance inks with enhanced print fidelity, mechanical durability, and colloidal stability across various substrate types.

Polyethylene glycol (PEG), a versatile non-ionic surfactant with excellent biocompatibility and robust chemical stability, offers significant potential for the precise regulation of interfacial polymerization (IP). In this study, PEG was introduced into the aqueous phase as an additive to modulate the interfacial diffusion behavior of piperazine (PIP). By systematically optimizing its molecular weight, concentration, and terminal group parameters, a polyamide (PA) active layer with a smaller and more uniformly distributed pore structure was successfully constructed. This optimized architecture effectively strengthened both the size exclusion and charge repulsion mechanisms of the nanofiltration (NF) membrane. Consequently, the optimal MP 1000 -10 membrane exhibited highly competitive NF performance, achieving an impressive Na 2 SO 4 rejection of 98.0% and a high water permeance of 11.5 L m −2 h −1 bar −1 . More importantly, tailoring the PEG terminal groups facilitated targeted control over the pore size and surface charge properties, significantly enhancing the removal of structurally and physicochemically diverse emerging organic contaminants (EOCs). Across a broad set of experimental parameters, PEG modification consistently delivers improved separation performance for membranes. With excellent stability, high efficiency and economic feasibility, this strategy provides solid technical and theoretical support for developing advanced separation membranes targeting high-efficiency EOCs removal.

The fast sol-gel transition of ABA triblock copolymers in aqueous solution has demonstrated excellent promise for various applications. However, the occurrence of gelation behaviors often needs precise temperature control or concentration regulation. Considering the advantages of precisely spatiotemporal control and noninvasive manner, the photo-controlled gelation behaviors are desirable but still remain a significant challenge, especially for ABA triblock copolymers. Herein, we reported a facile strategy for spatiotemporal photo-modulation of reversible gelation of ABA triblock copolymers. The pH-responsive ABA triblock copolymers [poly( N,N - diethylaminoethyl methacrylate)- b -polyethylene glycol- b -poly( N,N -diethylaminoethyl methacrylate), PDEAEMA-PEG-PDEAEMA] were synthesized and used for preparing photobase generator (Malachite green carbinol base, MGOH)-containing micellar solution. Under ultraviolet irradiation, the MGOH in PDEAEMA-PEG-PDEAEMA micelles could rapidly generate OH − , resulting in deprotonation and hydrophobization of PDEAEMA chain, finally achieving micellar reconstruction and in situ gelation transition. This study demonstrated not only a photo-controlled reversible sol-gel transition of ABA triblock copolymers without the limitations associated with conventional photosensitive reagents, but also a low-cost and fast system for intelligent monitoring, early warning, and rapid shielding of ultraviolet rays. Considering the easily available agents, simple preparation process and high flexibility in tuning hydrogel properties, this strategy opens up a promising avenue to develop photo-controlled hydrogels for various applications without involving complex synthesis of photosensitive polymers.

Cracks are inevitable during the service of cement-based facilities. The application of microcapsule technology to cementitious materials has realized the self-healing of cracks. In this research, tetraethylenepentamine (TEPA) was successfully encapsulated with polyethylene glycol (PEG)/polyurea shell by integrating melting-dispersion-condensation and interfacial polymerization method. The average diameter of final microcapsules prepared at 300 RPM was 666.9 ± 345.8 μm and the shell thickness was 45.5 ± 1.6 μm. The final microcapsules demonstrated good dispersibility and thermal stability. The normalized strength of the final microcapsules ranged from 0.6 MPa to 1.0 MPa. Moreover, the final microcapsules could remain stable completely both in ambient water and saturated calcium hydroxide (Ca(OH) 2 ) solution for 12 h. Additionally, the final microcapsules remained integral structure during mixing with fresh cement paste and were uniformly dispersed in the hardened cement paste. When microcapsules dosage was 3.0 wt%, the compressive strength of 28 days exceeded 50 MPa and the self-healing rate of compressive strength reached the highest, up to 27.5%. After self-healing, specimens containing microcapsules exhibited excellent resistance to water penetration. The single microcrack of self-healing cement paste with hydration ages of 7 days, 28 days, or even 56 days could be repaired to varying extent and the maximum repairable microcrack width was 145.6 ± 21.6 μm.

Nanofiltration (NF) for advanced drinking-water treatment has long been constrained by the need to remove contaminants while preserving beneficial mineral ions in health-oriented drinking water. Herein, an ethylene-glycol (EG)-regulated aqueous microenvironment was introduced to tailor the interfacial polymerization process. EG-mediated hydrogen bonding and modified interfacial thermodynamics jointly regulated piperazine diffusion, interfacial transport, and polymerization kinetics, producing polyamide NF membranes with enhanced negative charge surface density and a more uniform effective pore structure. Compared with the pristine membrane, the EG-20 membrane exhibited a thinner, more hydrophilic, and more negatively charged selective layer, together with a narrower pore-size distribution. The optimized EG-20 membrane achieved a permeance of 23.6 L m −2 h −1 bar −1 while maintaining Na 2 SO 4 rejection above 95.5%. In the treatment of natural surface water, dissolved organic matter removal reached approximately 92.1%, while partial passage of beneficial mineral ions was maintained, enabling effective organic contaminant removal with mineral preservation for health-oriented drinking water treatment. Moreover, high rejection of PFAS and antibiotics was maintained, mainly because steric exclusion and enhanced electrostatic repulsion compensated for the moderately enlarged effective pores. In addition, the membrane showed improved antifouling performance, as enhanced surface hydration and electrostatic repulsion reduced foulant adhesion and suppressed irreversible fouling. Overall, this microenvironment-regulation strategy provides a feasible route for developing NF membranes that integrate effective contaminant control, mineral preservation, and stable operation.

A novel coaxial wet spinning strategy is reported to fabricate shape stabilized phase change aerogel fibers (C f PCF). • The fibers feature hierarchically porous flower-like PUPCM clusters engineered by CNC-directed hydrogen bonding. • The C f PCF exhibits a high phase change enthalpy (115.6 J/g), ultralow thermal conductivity (0.076 W·m −1 ·K −1 ). • The C f PCF fabrics enable outstanding infrared stealth (Infrared detection temperature decreased by 51 °C). The escalating demand for advanced fibrous materials integrating dynamic thermal management and infrared stealth has spurred continuing innovation. Traditional porous phase change fibers (PCFs) suffer from two critical deficiencies: solid-liquid phase change materials (SLPCMs) leakage and gas-solid interface degradation. Herein, we present a novel coaxial wet spinning strategy to fabricate porous shape stabilized phase change fibers (C f PCFs). The aerogel core is prepared via cellulose nanocrystals (CNCs)-directed crystallization of polyurethane-based shape stabilized PCMs (PUPCMs) that were synthesized through crosslinking polyethylene glycol with hexamethylene diisocyanate, inherently eliminating liquid leakage. Thanks to strong intermolecular hydrogen bonding interactions between CNCs and PUPCMs, in-situ crystallization and assembly of PUPCMs proceed on CNC-directed three-dimensional scaffolds via ice templating, generating flower-like crystal clusters with hierarchical porosity. This unique structure offers dual benefits: 1) Robust anchoring of shape stabilized PUPCM to prevent leakage; 2) Excellent properties of high phase change enthalpy (115.6 J/g) and porosity (69.35%), ultralow thermal conductivity (0.076 W·m −1 ·K −1 ), and superior thermal stability (91.35% enthalpy retention after 600 cycles). The as-woven C f PCF fabric demonstrates exceptional thermal buffering performance, achieving a temperature lag of up to 750 s at 80 °C. This effect stabilizes the temperature through phase-change endothermy and reduces infrared-detected temperatures by 51 °C. This work presents a new pathway for developing next-generation intelligent fibrous materials with integrated functionality.

PEG400 broadens the debinding temperature window by ∼100 °C, enabling stepwise resin decomposition in VPP alumina. • Early PEG decomposition constructs 3D pores for efficient gas escape, suppressing delamination and cracks. • 10 vol% PEG optimizes defect control, achieving 234 MPa flexural strength (30% improvement) and 97.1% relative density. • Debinding window engineering is a generalizable strategy for defect regulation in light-cured 3D-printed ceramics. To address the critical challenges of narrow debinding window and defect formation in vat photopolymerization (VPP) 3D-printed alumina ceramics with high resin content (as high as 50 vol%), this study introduces polyethylene glycol (PEG400) as an auxiliary organic phase. The concentrated thermal decomposition of the single-resin system, typically occurring within a sharp temperature range of 300–500 °C, was transformed into a stepwise process spanning 200–500 °C by PEG pre-decomposition. This window broadening of ∼100 °C facilitated early gas release through interconnected pore channels formed at low temperatures, thereby alleviating internal pressure and stress accumulation during main resin decomposition. Quantitative X-ray computed tomography analysis confirmed significant defect suppression, with the 10 vol% PEG group (P1) achieving the lowest average defect volume and delamination fraction. Consequently, sintered samples exhibited 30% improvement in flexural strength (234 MPa) and 97.1% relative density. These results demonstrate that broadening the debinding temperature window is an effective strategy for defect control and mechanical property enhancement in VPP ceramics.

In the traditional system, rapid gas release leads to internal pressure accumulation and defect generation, resulting in a mechanical strength of only 185 MPa. In contrast, PEG decomposition constructs a connected pore network, achieving efficient debinding in a broadened temperature window of 200–500 °C, significantly reducing defects, and ultimately increasing the mechanical strength to 234 MPa, providing a new efficient debinding pathway for high-performance ceramic 3D printing.

Dynamic thermal-moisture management is crucial for alleviating the “wet-cling” discomfort and heat stress during vigorous activity. However, achieving massive macroscopic deformation, rapid actuation, and intrinsic flexibility simultaneously remains challenging for smart textiles. Herein, a hierarchical structural engineering strategy utilizes a programmable moisture-responsive polyurethane to develop an adaptive moisture-responsive flap textile (MRFT). By optimizing hydrophilic soft segments and leveraging strong endogenous adhesion, the resulting moisture-responsive textile achieves an optimal mechanical-actuation balance, rapidly bending 140° within 40 s. It demonstrates exceptional interfacial durability, maintaining reversible actuation across 100 standard wash cycles. The integrated MRFT features asymmetric flaps that autonomously open under high humidity to create macroscopic ventilation pathways. This yields an outstanding water vapor transmission rate of 278.9 g m − 2 h − 1 and a minimal wet adhesion force of 1.07 cN. The MRFT efficiently dissipated heat and sweat, reducing microclimate temperature by 3.3°C and relative humidity by 39.1% versus commercial cotton during human exercise trials. This self‑regulating strategy effectively overcomes the inherent limitations of conventional textiles in sweat wicking and moisture permeability, establishing a robust paradigm for next‑generation intelligent athletic apparel.

CeLut improves the low solubility and poor bioavailability of luteolin. • CeLut synergistically improves cellular metabolism under oxidative stress conditions. • PDT@CeLut features a fluffy structure and dynamic adaptability to wound. • PDT@CeLut balances oxidative stress and the hypoxic microenvironment in burn wounds. • Excellent biosafety and convenient treatment approach, with clinical potential. Skin burns remain challenging in clinical treatment due to their complex wound morphology, high oxidative stress, hypoxic microenvironment, and severe inflammatory response. Developing strategies for highly effective biomaterials with precise biological functions has become an urgent priority in addressing clinical challenges. This study developed a fluffy fibrous scaffold loaded with a metal-polyphenol nanocomposite (CeLut). The scaffold possesses water-retaining capacity, three-dimensional fluffiness, and interlayer porosity, which promote cell spreading, migration, and proliferation. It is capable of sustained release of luteolin and Ce ions, efficiently scavenging ROS while modulating oxygen metabolism. These synergistic effects of physics and biomaterials science rebalance the oxidative and hypoxic microenvironment of burn wounds, significantly accelerating wound healing, promoting skin regeneration, and alleviating inflammatory responses in a mouse burn model. The results showed that within 14 days after a second-degree burn, the recovery rate of functional skin structure reached 96.3%. These findings demonstrate the therapeutic value of fluffy fibrous scaffold containing metal-polyphenol nanocomposites in promoting burn wound repair, thereby providing a new strategy for the preparation of customized multifunctional bioactive scaffolds.
