The synthesis of size-controlled monodisperse polymer particles without emulsifiers remains a significant challenge in polymer science. Poly(acrylonitrile-co-methyl acrylate) (poly(AN-co-MA)) spherical particles with excellent monodispersity (PDI < 0.1) were successfully developed via a one-pot polymerization strategy using acrylonitrile (AN) and methyl acrylate (MA). The effects of key parameters, including pH value, monomer concentration, initiator concentration and temperature, on the particle size of monodisperse poly(AN-co-MA) particles were systematically investigated. Furthermore, the formation mechanism of the PAN-based particles was elucidated through a combination of characterization including Scanning Electron Microscope, Transmission Electron Microscope, Dynamic Light Scattering, water contact angle measurements, Fourier Transform Infrared Spectroscopy, Proton Nuclear Magnetic Resonance, Wide-Angle X-Ray Diffraction and Differential Scanning Calorimetry, among others. The results demonstrate that the inherent reactivity difference between AN and MA drives a temporal composition evolution. MA is preferentially incorporated in the early polymerization stage, facilitating nucleation of primary particles, while AN dominates in the later polymerization stage. Thereby, the continuous shift toward AN-rich segments significantly enhances the crystallinity and mechanical rigidity of the particles, which as a result ensures the formation and maintenance of their perfect spherical morphology. Owing to its operational simplicity and high product purity, this method shows great potential for industrial-scale production.

Water bath temperature plays a critical role in regulating the crystallization and growth kinetics during the co-precipitation process. In this work, MgAl 2 O 4 precursors were synthesized via co-precipitation route under gradient water bath temperatures, and the resulting transparent MgAl 2 O 4 ceramics were fabricated by hot isostatic pressing (HIP). The results indicate that lower water bath temperatures promote the formation of low-crystallinity granular precursors, whereas higher temperatures facilitate crystal growth and lead to rod-like precursors with higher crystallinity. The morphology of the calcined powders closely reflected that of the corresponding precursors. The HIP process eliminated the vast majority of pores, producing transparent ceramics. Subsequent annealing in air further improved the transmittance. Notably, the sample prepared at 30 °C exhibited high transmittance in the visible region and low defect density.

This paper examines antecedents to the successful use of Virtual Cultural Tourism and the ways in which virtual realities can add value to Cultural Tourism offers. Success can be seen to derive from the deeper understanding of consumers’ preferences and motivations to engage with Virtual Cultural Tourism. It is also necessary to see these initiatives from the perspective of multiple stakeholders: the armchair traveller, the frequent flyer and the service provider at destinations. The latter include public sector providers such as park site managers, museum curators, interpretation and information services for tourism as well as the private sector developers.

Chitosan oligosaccharide (COS) derivatives present significant potential as antimicrobial agents. Our previously developed geraniol (Ger) grafted Chitosan oligosaccharide (COS-Ger) has demonstrated commendable solubility and antibacterial activity. To further improve its effectiveness, exploring methods for bacterial targeting could be a beneficial approach. Therefore, we herein report a novel dual-functional derivative, phenylboronic acid (PBA) and Ger co-modified COS, by strategically integrating PBA into the COS-Ger framework. The molecular structure of the derivative has been validated through several characterization techniques. Biological evaluations demonstrated that PBA incorporation synergistically enhanced the compound's bacterial targeting, resulting in markedly improved antibacterial performance. PBA incorporation synergistically enhanced the compound's bacterial targeting. Specifically, at a low concentration of 0.2 mg/mL, the inhibition rate of PBA–COS–Ger against Staphylococcus aureus ( S. aureus ) reached 73.10%, significantly outperforming that of COS-Ger (30.61%). Moreover, it achieved nearly 100% inhibition against both S. aureus and Escherichia coli ( E. coli ) at 1.0 mg/mL. These results clearly indicate that the grafting of PBA greatly enhanced the antibacterial ability of COS-Ger. The practical potential of this derivative was preliminarily verified through a preservation experiment on cherry tomatoes. This approach establishes a conceptual platform for the rational design of highly efficient, bio-based antimicrobial agents.

Biodegradable plastics, widely recognized as promising substitutes for conventional plastics, still face the challenge of microplastic contamination to require in-depth assessments of combined pollution scenarios. This study explored the adsorption of 1-chloronaphthalene (PCN-1) by biodegradable plastics including poly(butylene adipate-co-terephthalate) (PBAT) and polylactic acid (PLA) with polyethylene (PE) as a conventional plastic control in seawater. The maximum adsorption capacity of PCN-1 on PLA/PBAT/PE in seawater reached 131.22/323.59/301.80 μg g −1 . The desorption efficiency of PCN-1 from PLA and PBAT was substantially lower than that from PE, suggesting that biodegradable plastics might pose reduced environmental risks due to low pollutant release. Interaction between PCN-1 and biodegradable plastics could be regulated by pH, which was attributed to the modulation of π-π stacking interactions. Salinity exerted a positive effect on the adsorption capacity of PCN-1 by PLA, PBAT, and PE; the maximum capacities (131.22/323.59/301.80 μg g −1 , respectively) were achieved at a salinity of 30‰. Pseudo-second-order model obtained good fitting on adsorption kinetics of PCN-1 on PLA while PBAT and PE exhibited higher consistency with the pseudo-first-order model. Thermodynamic analysis based on enthalpy (ΔH) and Gibbs free energy (ΔG) changes revealed that PCN-1 adsorption on PLA was an endothermic process, while the adsorption on PBAT and PE was exothermic. Collectively, the capture of PCN-1 by biodegradable plastics is predominantly governed by three key factors: crystallinity of the plastic matrix, π-π interaction between the plastic and PCN-1, and hydrophobic interaction.

Conducting polyaniline (PANI) and porous carbon fibrous membranes to construct composite electrode materials is one of the hotspots for preparing high-performance supercapacitors. The key is realizing the homogeneous dispersion of the two materials, carbon/PANI, and the connection interface with considerable firmness and strength. Therefore, based on the interfacial covalent bonding strategy, the N-P co-doped carbon membrane and PANI hybrid (NPCM@PANI) materials were designed and constructed. NPCMs were used as substrates to functionalize with nitric acid and ND42, and then co-aniline in situ on the surface of NPCMs. This approach aimed to obtain a hybrid material with high specific capacitance, using NPCM as the substrate. The resulting NPCM@PANI hybrids have a specific capacitance of up to 552 F/g (1 A/g), a small equivalent series resistance of 1.1 Ω and a low transfer diffusion resistance of about 1 Ω in 1 M H 2 SO 4 electrolyte. The capacitance performance is still 78% after 1,000 cycles, which provides excellent capacitance properties. Graphical abstract

Electrocatalytic nitrite reduction offers a sustainable route to convert hazardous water pollutants into valuable ammonia, yet its efficiency is often stifled by the competitive hydrogen evolution reaction (HER) and sluggish kinetics. Herein, we report the rational design of a quinary alloy catalyst, Co25Cu15@NiMnMg, featuring a distorted face-centered cubic (FCC) structure for highly efficient NO2RR. By precisely tailoring the metal ratios via a sol–gel method, the electronic structure and active site distribution were optimized to break the linear scaling relations. In an alkaline electrolyte, the catalyst delivers an outstanding ammonia yield of 3528.04 μg h–1 cm–2 with a Faradaic efficiency of 96.8% at −0.5 V vs RHE, significantly outperforming most binary benchmarks. Mechanistically, in situ Fourier transform infrared spectroscopy (FTIR) and electrochemical X-ray photoelectron spectroscopy (XPS) reveal a distinct site-specific synergy: Co sites act as the primary centers for NO2– capture and hydrogenation, while Cu moieties regulate the local hydrogen environment to suppress the HER. Additionally, the Ni–Mn–Mg matrix serves as a structural scaffold to enhance conductivity and stability. This work presents a compelling “multielement synergy” strategy for developing advanced electrocatalysts, offering a dual solution for environmental remediation and green energy carrier synthesis.

The rational design of long-lifetime and low-energy-consumption ceramic membranes is challenging, especially for the sustainable treatment of industrial wastewater to solve environmental pollution issues. In this work, a whisker reinforcement strategy is proposed to fabricate gradient composite ceramic membranes with enhanced interfacial bonding strength. The introduction of a whisker intermediate layer effectively mitigates the cracking and deformation issues caused by mismatched shrinkage between membrane layers during co-sintering. The resulting composite ceramic membrane exhibits an average pore size of 95 nm and a permeance of 1340 L m −2 h −1 bar −1 . The membrane exhibits a rejection rate of 99.6% for carbon particle suspensions and maintains a permeance recovery ratio of 85% after six separation-backwashing cycles. This work provides a promising and cost-effective strategy for the design of highly stable composite ceramic membranes, paving the way for their practical application in industrial wastewater treatment.

The biodegradation of polycyclic aromatic hydrocarbons (PAHs) involves complex metabolic interactions among multiple degradation pathways. However, how interactions among different pathways influence the overall degradation efficiency remains poorly understood. In this study, Pseudoxanthomonas sp. G3, an efficient degrader of phenanthrene (PHE) and pyrene (PYR), was used to investigate pathway interactions under mixed-PAH conditions. Genomic and metabolomic analyses revealed that strain G3 degrades PHE and PYR through three pathways: the phthalate pathway (with phthalic acid as the dead-end product), a shared catechol degradation pathway, and the benzoate degradation pathway. Notably, PYR induced the benzoate degradation pathway, representing a previously unreported metabolism of PYR by bacteria. Integrated analyses revealed that PHE inhibits PYR degradation via dual mechanisms. Specifically, PHE preferentially utilizes the PYR-induced benzoate degradation pathway, thereby diverting metabolic flux and impeding PYR degradation. Moreover, the benzoate degradation pathway further inhibits the catechol degradation pathway, intensifying suppression of PYR degradation. These findings elucidate mechanistic insights into the interactions among the biodegradation pathways under mixed-PAH stress and provide a theoretical basis for targeted improvement of the efficiency and predictability of mixed-PAH degradation.

Co-loaded CNT with high Co 2+ content of 61.07% exhibited enhanced nanozyme activity. • P2 possessed a safe Co-ion release content far below the threshold of 20 ppm. • P2 exhibited good well-rounded properties and excellent anti-inflammatory activity. Excessive reactive oxygen specie (ROS) is not conducive to bone repair, which is prone to generate during the initial hematoma inflammatory phase following poly( L -lactic acid) (PLLA) bone scaffold implantation and the potential inflammation caused by its acidic degradation products. This study proposed introducing cobalt (Co)-based nanozyme into the PLLA scaffold, and focused on improving the dispersion between nanozyme and the PLLA matrix as well as enhancing the activity of nanozyme itself for efficiently scavenging ROS. The Co was loaded on the surface of carbon nanotube (CNT) for achieving uniform dispersion, and then calcined under different atmospheres for enhancing nanozyme activity via regulating the Co 2+ /Co 3+ ratio and optimizing the electronic structure. It was found that the nanozyme that was calcined in an N 2 atmosphere followed by phosphorylation exhibited a superior ROS-scavenging ability, which was attributed to its high Co 2+ content of 61.07% that facilitating the redox cycling and the optimization of its electronic structure by P doping. As a result, the composite scaffold (P2) at a nanozyme loading of 2 wt% possessed superior intracellular ROS-scavenging ability and downregulation of key inflammatory cytokines compared to the pure PLLA scaffold. It also possessed good cytocompatibility for cell adhesion and proliferation, and exhibited upregulated expression of the pro-angiogenic VEGF factor.

NiFe-layered double hydroxides (LDH) exhibit excellent oxygen evolution reaction (OER) activity after doping and modification treatments, but their stability under high current densities is considerably limited. The rare-earth element cerium (Ce), owing to its variable valence states, can enhance structural stability by inducing lattice distortion and dynamic redox cycling when incorporated as a dopant. Meanwhile, oxalate ions (OA²⁻), with their larger spatial volume and more uncoordinated carboxylic acid groups (-COOH), act as proton transfer carriers. The synergistic effect between Ce and OA accelerates the OER kinetics of CeNiFe-LDH-OA@NF. The CeNiFe-LDH-OA@NF electrode demonstrates overpotentials of only 242 mV and 256 mV at high current densities of 100 mA cm⁻² and 200 mA cm⁻², respectively. Moreover, it exhibits exceptional stability under high current conditions, showing almost no decay in overpotential after continuous operation for 140 h at 100 mA cm⁻², with a minimal degradation rate of 0.5%. As a proton transfer carrier, the oxalate anion significantly enhances OER kinetics by optimizing the proton conduction pathway at the electrocatalytic interface. In cyclic voltammetry (CV) measurements, a negative shift and an increased slope of the characteristic reduction peak were observed, confirming that OA modification effectively regulates the hydroxyl adsorption energy barrier. The CeNiFe-LDH-OA@NF electrode demonstrates higher surface hydroxyl affinity.

Chiral neuromorphic devices, representing an advanced synchronous integration of neuromorphic engineering and chiral optoelectronics, offer a new pathway for intelligent computing and high-dimensional sensing technologies. In this study, a charge-transfer co-crystal helical structure based on pyrene and 1,2,4,5-tetracyanobenzene (TCNB) was prepared via a simple solution process. This structure exhibits chiral emission by virtue of chiral supramolecular assembly, owing to the strong solvent-solute interactions. To enhance the charge storage performance, a heterojunction with phase-separated characteristics was constructed by one-step drop-casting TIPS-pentacene and pyrene–TCNB solutions. The heterojunction effectively modulates the interfacial charge trapping and separation processes, thereby enhancing the chiroptical sensitivity. Under optical pulse stimulation, the device simulated multiple synaptic functions, including paired-pulse facilitation (PPF), pulse-duration-dependent and intensity-dependent plasticity, and biomimetic learning behaviors. This work provides a feasible technological pathway of chiral artificial synapse construct toward photonic neuromorphic computing system developing.
