Summary: Developing high-performance epoxy nanocomposite coatings with excellent fire safety, thermal conductivity, and mechanical performance has been a challenging task. In this study, a multifunctional nanohybrid (MXene@IL) was fabricated using an electrostatic self-assembly strategy, and epoxy nanocomposite coatings based on MXene@IL (EP/MXene@IL) were prepared. The MXene@IL nanohybrids showed excellent dispersion and interfacial compatibility in the epoxy matrix. The addition of 2.0 wt% MXene@IL resulted in a significant improvement in fire safety, with a reduction in peak heat release rate by 43.76% and smoke factor by 65.99% compared to virgin epoxy resin (EP). Furthermore, EP/MXene@IL-2.0 exhibited an increased thermal conductivity by 21.56%. The flexural and impact strengths of EP/MXene@IL-1.0 were also improved by 10.24% and 44.73%, respectively. MXene@IL acted as a co-curing agent, facilitating the curing reaction of the epoxy nanocoatings. This study provides a feasible strategy for designing multifunctional MXene@IL-based epoxy nanocomposite coatings.

Summary: This work explores the use of urea, ternary amine T403, and diaminodecane DA-10 as feedstocks for the production of self-foaming polyurea foams (PUrFs). The addition of 3 wt% nano SiO2 significantly improves the nucleation performance of PUrFs, while a higher loading of nano SiO2 (5 wt%) increases the melt strength but is not beneficial for foaming. An appropriate feeding ratio of T403 to DA-10 (1/1) improves crystallinity and promotes nucleation. The PUrF-3-50 sample exhibits the highest comprehensive performance, including an average pore size of 429 μm, an apparent density of 298 kg/m³, and a compressive strength of 3.2 MPa (75% strain). The hysteresis of PUrF-3-50 is high (>90%) and stable. This work presents a new strategy for the preparation of PUrFs and expands the application of urea-based polymers.

Summary: This study focused on the semihydrogenation of acetylene in an ethylene-rich stream using two alloyed Pt catalysts PtCu and PtCo. The PtCu catalyst showed higher activity and ethylene yield compared to PtCo due to its higher unoccupied Pt d-orbital density. This indicates that alloying Pt with Cu is more promising for industrial relevant SHA catalyst.

Summary: The use of machine learning to predict the performance of specific adsorbents in phosphate adsorption shows great promise in saving time and revealing underlying mechanisms. However, the small size of the dataset and insufficient detailed information limits the model training process and the accuracy of results. To address this, the study employs a fuzzing strategy that replaces detailed numeric information with descriptive text messages on the physiochemical properties of adsorbents. This strategy allows the recovery of discarded samples with limited information, leading to accurate prediction of adsorption amount, capacity, and kinetics. The study also finds that phosphate uptake by adsorbents is generally through physisorption, with some involvement of chemisorption. The framework established in this study provides a practical approach for quickly predicting phosphate adsorption performance in urgent scenarios, using easily accessible information.
