Transition metal chalcogenides have been considered as one kind of the most potential candidate catalysts for oxygen evolution reaction (OER). However, the inevitable sulfur loss during reconstruction process destructs the chemical and electronic structure of catalysts. Herein, we proposed directional metal element migration to fix sulfur on near-surface region, and evaluated the effect of lattice oxygen compensation on the stability of surface sulfur. Besides, an ‘etching-compensation factor’ of lattice oxygen is defined as a descriptor on the OER stability with coupled O─O as the key intermediates. It is found that the migration of Fe and S in opposite directions enables high voltage-dependent reversibility of Ni─O─Fe units during OER for self-healing of electrode. The further produced full gradient NiFe-sulfide electrode can stably work for more than 50 000 CV cycles at the scan rate of 50 mV s −1 , and 800 h of chronopotentiometric at current density of 100 mA cm −2 .

The widespread use of petrochemical plastics has made environmental problems and health risks increasingly prominent. While bioplastics hold promise as alternatives, their limited heat resistance and shaping capabilities hinder widespread adoption in high-performance engineering. Here, we present an innovative supramolecular network that utilizes cellulose as a molecular framework, complemented by acrylamide molecules for in situ polymerization. By applying ethanol for structural reconstruction, we create a self-reinforcing bioplastic (S-bioplastic) with a tensile strength of 76 MPa and a flexural modulus of 4.7 GPa. This S-bioplastic supports multiple molding techniques—such as injection and compression molding—and exhibits remarkable environmental adaptability, with thermal stability up to 180°C and low-temperature resilience to −196°C. Compared to conventional plastics, S-bioplastic offers enhanced mechanical properties, biocompatibility, biodegradability, and recyclability, achieving a 95% retention of strength. A techno-economic analysis underscores its value proposition. This research highlights a method for converting bamboo-based materials into high-value bioplastics, providing a promising strategy to address plastic pollution while developing lightweight, high-performance materials for aerospace applications.

Polypropylene (PP) mesh implanting has emerged as a breast reconstruction approach to restore normal anatomical contours. However, developing biomedical PP mesh with enhanced anti-inflammatory properties, superior mechanical strength, and efficient manufacturing remains a significant challenge. In this study, we report a drug-loading PP mesh by incorporating triclosan into femtosecond (fs) laser-treated PP mesh scaffolds. The fs laser induced micro/nano structures significantly enhanced the drug-loading capacity and antibacterial efficacy of triclosan-modified PP mesh, as indicated by the area of inhibition rings (2.5-fold relative to the blank groups). In vivo breast reconstruction experiments using female Sprague-Dawley (SD) rats demonstrate accelerated scab formation and wound healing. Additionally, the Enzyme-linked immunosorbent assay (ELISA) test reveals high vascular density (11.43 µg/mL of CD31 and 0.32 µg/mL of CD163) and reduced proinflammatory cytokine levels (145 pg/mL of IL-6 and 33 pg/mL of TNF-a), further confirming the anti-inflammatory properties of the fs laser-treated triclosan-modified PP mesh. This study presents a novel approach to improving the clinical performance of PP meshes for biomedical applications.

The management of Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome is severely hampered by the inability of existing therapies to achieve conformal fitting and sustained drug release within the dynamic, moist vaginal environment. Herein, we report a novel Janus-structured microneedle (MN) system engineered from a poly(vinyl alcohol)/silk fibroin (PVA/SF) hybrid that overcomes these critical limitations through intelligent, hydration-triggered shape adaptation. A facile one-pot process induces spontaneous spatial segregation, forming an asymmetric bilayer architecture with a PVA-rich upper layer and an SF-enriched lower layer. This unique structure enables the device to be pre-programmed into a compact coil for minimally invasive insertion, which subsequently unfurls upon vaginal moisture exposure to achieve conformal contact with irregular wound surfaces. Crucially, we decipher the shape memory mechanism through 2D correlation spectroscopy and molecular dynamics simulations. These analyses reveal a sequential disruption of hydrogen bonds, while hydrophobic interactions from SF β-sheets provide exceptional mechanical stability in the hydrated state. In a rat model of severe vaginal injury, the arbutin-loaded MN (ARMN) scaffold orchestrates a holistic healing process—effectively scavenging ROS, suppressing IL-6-mediated inflammation, promoting VEGF-driven angiogenesis and PCNA-enhanced proliferation, and mitigating surgery-induced dysbiosis. This work establishes a pioneering paradigm of stimuli-responsive, self-adapting medical devices for transformative therapy in complex mucosal tissue regeneration.

High-efficiency multistage solar interfacial evaporation requires covers that maximize solar spectrum transmission to the absorber while limiting thermal losses. Here, we establish a coupled numerical and experimental framework to tune the optical properties of transparent silica aerogels.We identify wavelengths < 500 nm as a critical, morphology-tunable scattering regime that also coincides with the AM 1.5G peak. Design maps suggest an optimal design in which a mean particle radius < 4 nm and a bulk density < 200 kg m −3 deliver total transmittance > 95% with haze < 5%. Further promotion in forward scattering can boost the transmittance even when haze is relatively high. Experimentally, guided by the multiscale model, we tuned the sol-gel process to reduce the silica aerogel mean scattering center radius from 4.9 to 3.1 nm, yielding a 5 mm-thick sample with a solar-weighted transmittance of 95.2%. Integrated as a greenhouse-selective cover in a 10-stage solar evaporation device, the optimized silica aerogel boosts the water production rate by 19.3%, from 5.22 to 6.23 kg m −2 h −1 , demonstrating that morphology tuning translates into system-level performance gains. These results provide actionable design rules and a validated predictive modeling framework for low-haze and high-transparency aerogel covers that enable efficient solar evaporation.

Obstructive lacrimal duct disease has long been a clinical challenge due to the limitations of traditional silicone stents, which are functionally simple, non-degradable, and prone to fibrosis-induced restenosis. In this study, we present a breakthrough approach in the development of a multifunctional, drug-loaded, biodegradable lacrimal duct stent based on electrospinning technology. By integrating mesoporous polydopamine nanoparticles loaded with dexamethasone (MPDA@DEX) into a PLCL/Gel composite matrix, we successfully fabricated a biomimetic stent that exhibits desirable mechanical properties, hydrophilic surface characteristics, and controlled drug release capabilities. In vitro, the stent demonstrated excellent anti-inflammatory and antioxidant activities, being associated with a shift of macrophages toward an M2-like phenotype, significantly reducing intracellular ROS levels, and contributing to an inflammation-repair balance via modulation of the MAPK/Hippo/FoxO signaling pathways. Transcriptomic sequencing further confirmed its ability to coordinate the regulation of the cellular transcription network, simultaneously suppressing pro-inflammatory pathways while activating repair mechanisms. In vivo experiments further validated the stent's capacity to significantly reduce inflammation at the implantation site, inhibit collagen deposition, and promote angiogenesis. This research provides an innovative solution for lacrimal duct repair with active regulatory functions, representing a promising transition from “passive support” to “active repair” in therapeutic strategies.

Graphene-based liquid crystals have ultra-high electric responsivity and hold great promise in fabricating light modulators with ultra-low-field driving and macroscopic centimeter-scale electrode spacing. However, their narrow bandgap and uncontrollable electroresponse severely restrict their modulated spectral region and performance, especially for the visible and ultraviolet regions. Here, we report a fluorographene liquid crystal, which has a wide bandgap of ∼5.5 eV and controllable electroresponse from modulation of fluorine doping ratio, and exceptional stability under deep-ultraviolet exposure. As a consequence, a fluorographene liquid crystal-based deep-ultraviolet electro-optic modulator is fabricated with negligible degradation after 5 h of ultraviolet irradiation under 0 and 12 V m −1 electric fields. The fluorographene liquid crystals expand the family of graphene liquid crystals and pave the way for broadening their applications in a variety of scenarios, as conceptually demonstrated with integrated sea-land-air solar-blind communication for smart port applications.

The insufficient understanding of the diffusion-reaction-polymerization coupling in membrane formation dynamics hinders the application of interfacial polymerization membranes in drug delivery and membrane separation. Here, the relationship between the hydrophilicity of the oil phase and water mass transfer behavior is taken as the breakthrough point. From the perspective of diffusion, the water mass transfer flux is positively correlated with the membrane thickness. From the perspective of polymerization, under the diffusion-limited aggregation model, the polymerization of oligomers leads to uneven membrane thickening. This accounts for the paradoxical observation that thicker membranes exhibit lower encapsulation and rejection rates. Building on a comprehensive understanding of membrane formation dynamics, an AI model that can predict performance with high precision was developed. Furthermore, universal regulation strategies can increase the encapsulation efficiency and rejection rate by 32.3–54.8% and 6.8–23.9%, respectively. This study provides both theoretical basis and technical approaches for designing high-performance microcapsule and separation membrane.

Perovskites with tunable compositions and structures are desirable electrocatalysts for water electrolysis. However, achieving efficient hydrogen evolution reaction (HER) in alkaline media using perovskite-based catalysts remains a significant challenge. Herein, a Cu-doped La 0.5 Ba 0.5 CoO 3–δ perovskite was synthesized via a sol-gel method, which exhibits enhanced HER electrocatalytic activity through the construction of dual active sites. X-ray photoelectron spectroscopy (XPS) and x-ray absorption fine structure (XAFS) analyses reveal that Cu doping simultaneously induces the oxidation of Co and the formation of oxygen vacancies, establishing a synergistic charge compensation between the dual active sites. Specifically, oxygen vacancies promote water dissociation by enhancing adsorption, while high-valence Co species reduce charge transfer resistance, thereby facilitating electron transfer during HER. As a result, the optimized La 0.5 Ba 0.5 Co 0.8 Cu 0.2 O 3–δ (LBCC 0.2 ) achieves low overpotentials of 160 mV and 228 mV at current densities of 10 and 100 mA·cm −2 , respectively. Moreover, the catalyst demonstrates outstanding stability, maintaining 200 h for HER operation, outperforming commercial Pt/C. This study highlights the advantage of dual active sites in boosting the intrinsic electrochemical activity and underscores the potential of Cu-doped perovskites for efficient hydrogen production. Graphical A Cu-doped La 0.5 Ba 0.5 CoO 3-δ perovskite (LBCC 0.2 ) was synthesized using a sol–gel method for alkaline hydrogen evolution reaction (HER). The resulting dual active sites, comprising Co species and oxygen vacancies, collectively enhance the electrical conductivity and accelerate HER kinetics of LBCC 0.2 . This leads to a low overpotential of 160 mV at a current density of 10 mA·cm −2 and an excellent stability over 200 h.

The development of high-performance, low-platinum (Pt)-loading catalysts for the oxygen reduction reaction (ORR) remains a critical challenge in proton exchange membrane fuel cells. Zirconium dioxide-carbon composite materials are prepared using the Zr-based metal-organic framework UiO-66 as a precursor. The support structure is modulated by controlling the pyrolysis conditions (700 °C, 800 °C, and 900 °C). Platinum nanoparticles are deposited onto the ZrO 2 -carbon composite framework using ethylene glycol as the reducing agent, yielding low-Pt-content Pt/U-X catalysts (X = 700, 800, 900). The findings demonstrate that the Pt/U-X catalysts exhibit superior electrocatalytic activity compared with commercial Pt/C catalysts. Pt/U-800 displays the highest mass activity (796.9 mA mg Pt −1 ), which is 3.64 times higher than commercial Pt/C (219.2 mA mg Pt −1 ). Furthermore, Pt/U-800 achieves 1250 mA cm −2 at 0.6 V and reaches a peak power density of 1820 mW cm −2 in fuel cell tests. The one-step composite of ZrO 2 and carbon, formed through the pyrolysis of UiO-66, facilitates an interfacial structure between ZrO 2 and Pt, optimizing the hierarchical pore structure of the support, and providing a promising, cost-effective alternative to traditional Pt/C catalysts for fuel cell cathod. Graphical ZrO 2 –carbon composite supports were derived from UiO-66 (a Zr-based metal–organic framework, MOF) by pyrolysis. Pyrolysis temperature regulates graphitization and oxygen vacancies (O v ), strengthening Pt–support interactions. The optimized Pt/U-800 catalyst forms a Pt δ+ –O v –Zr 3+ interface and exhibits enhanced oxygen reduction reaction (ORR) activity with higher half-wave potential (E 1/2 ) and mass activity (MA) than commercial Pt/C.

Unlike conventional preservation methods that passively store food, active packaging materials proactively prevent microbial contamination and, when combined with polyphenols, can also serve as intelligent systems for freshness monitoring. In this study, polypropylene (PP)-based membranes incorporating curcumin (Cur) and quercetin (Quer) were developed and characterized to evaluate their potential use in food packaging applications. The membranes exhibited low water vapor permeability, indicating strong barrier properties. Among the formulations, the PP-Cur-A2 (Cur-loaded PP-A2, where A2 refers to chlorinated polypropylene (PP-Cl) obtained from Sigma-Aldrich) membrane showed superior mechanical performance (tensile strength: 24.10 ± 1.06 MPa; elongation at break: 378%) and achieved complete curcumin release within 20 days. Importantly, the membranes displayed distinct color transitions under different pH conditions, confirming their functionality as pH-responsive indicators. In addition, when tested both with fresh shrimp in Petri dishes and in aqueous ammonia environments, the membranes exhibited visible and progressive color changes in response to spoilage-related volatile compounds. Overall, the developed membranes demonstrated efficient bioactive release, excellent barrier characteristics, and reliable colorimetric indicator functionality, underscoring their promise for sustainable and intelligent food packaging applications.

Bisphenol A (BPA), an emerging wastewater contaminant, poses significant ecological risks even in trace concentrations, necessitating advanced removal strategies. In this study, a novel γ-Fe2O3-embedded nitrogen-doped polydopamine-derived carbon composite adsorbent (Fe-PC) was synthesized using polydopamine as a self-nitrogen-doped carbon precursor rather than a conventional shell material. The Fe-PC adsorbent exhibited a high BPA adsorption capacity of 423.86 mg g–1 and rapid equilibrium within 120 min. Adsorption kinetics followed a pseudo-second-order model (R2 = 0.999), while equilibrium data aligned with the Langmuir isotherm, indicating monolayer chemisorption is the dominant mechanism. Thermodynamic analysis confirmed that the process is spontaneous and endothermic. Mechanistic investigations revealed that γ-Fe2O3 introduces abundant active sites, enabling synergistic adsorption via chemical bonding, π–π interactions, hydrophobic interactions, and Fe3+ coordination with BPA hydroxyl groups. Combining high adsorption capacity, rapid kinetics, and stability, Fe-PC offers a promising strategy for efficiently removal of emerging contaminants from water.
