When partial discharges occur in air-insulated equipment, the air decomposes to produce a variety of contamination products, resulting reduction insulation performance insulated equipment. By monitoring concentration typical decomposition products (CO, NO, and NO2) within potential faults can be diagnosed. MoS2 has shown promising applications as gas-sensitive semiconductor material, doping metal oxides improve properties material. Therefore, this work, been doped using popular (ZnO, TiO2)...

The insulation characteristics and decomposition components of C4F7N/N2 gas mixture, a potential substitute for SF6, were first explored by breakdown experiments/gas chromatography–mass spectrometer. structural properties C4F7N molecule the mechanism mixture analyzed based on density functional theory calculation ReaxFF molecular dynamics simulation. We found that has great self-recovery performance. in discharge mainly produces CF4, C2F6, C3F8, CF3CN, C2F4, C3F6, C2F5CN, among which...

In this paper, the adsorption of four types SF6 decomposed products over perfect and defective (containing one S or W vacancy) WS2 monolayer was theoretically investigated using density functional theory (DFT). By calculating energy, electron transfer, comparing band structure states (DOSs) before after gas adsorption, physical chemical interactions can be evaluated. The results show that adsorptions molecule are mainly physisorption with low possibility new bond formation. presence vacancy,...

Abstract Polyethylene oxide (PEO) based solid polymer electrolytes (SPEs) are incompatible with the 4 V class cathodes such as LiCoO 2 due to limited electrochemical oxidation window of PEO. Herein, a number binders including commonly used PEO, polyvinylidene fluoride (PVDF), and carboxyl‐rich (CRP) sodium alginate (Na‐alginate) carboxymethyl cellulose, studied for application in all‐solid‐state batteries (ASSPBs). The results show ASSPBs CRP exhibit superior cycling performance up 1000...

Single-atom catalysts (SACs) have provided new impetus to the field of catalysis because their high activity, selectivity, and theoretically full utilization active atoms. However, ambiguous activation mechanism prevents a clear understanding structure-activity relationship results in great challenge rational design SACs. Herein, by combining density functional theory (DFT) calculations with machine learning (ML), we explore 126 SACs analyze develop for electrocatalytic nitrogen reduction...
