The resulting PI-derived graphene (PIDG) obtained under high-intensity laser irradiation possessed a high degree of graphitization, a low

Plasma-activated water (PAW), an emerging and cost-effective disinfectant produced from the interactions between non-thermal plasmas with water, was generated with a newly designed hybrid plasma discharge (HPD) reactor. The HPD reactor produces two simultaneous plasma discharges within one power source, one from the high-voltage electrode above the liquid surface, and the other from the ground electrode

Currently, the research in energetic materials focuses on exploring new design strategies to seek the ideal balance between high performance and molecular stability. In this work, the intramolecular integration strategy with the introduction of 1,2,4-triazine between triazole skeleton and pyrazole skeletons to develop the advanced 5/6/5 fused energetic materials is proposed. The six-membered skeleton

A novel polyaniline (PANI) partially carbonized core-shell material (Fe3O4@PANI-p) was prepared and used to activate peroxymonosulfate (PMS) for tetracycline (TC) degradation. Partial carbonization of the polyaniline layer introduced carbon catalytic sites into the catalyst. The polyaniline/carbon bilayer structure of the catalyst confined the metal oxides in the shell layer, which improved the catalytic

Copper substrates are widely used in heat exchangers due to their low cost and high thermal conductivity. While copper substrates have been modified to exhibit non-wetting property via lubricant infusion to enhance condensation heat transfer efficiency, these engineered surfaces often lack chemical robustness and lubricant retention, limiting their long-term use without maintenance. In this work, we

Supercritical water partial oxidation (SCWPO) is a clean and efficient organic waste resource utilisation method. Indole is an essential intermediate in the thermochemical conversion process of nitrogenous organic waste, and its conversion is often regarded as the rate-limiting step in these processes. However, the detailed reaction mechanism of the SCWPO process of indole is still unclear. This paper

Composite insulator is an important component of outdoor insulation systems. It works in complex environments and faces a series of problems such as surface contamination, loss of hydrophobicity, and accumulation of surface charges, which may eventually lead to flashover. Aiming to solve these problems in a simple and scalable method, we propose a multifunctional nano-coating based on SiO2/PDMS/EP
