The growing application of gas insulated switchgear (GIS) in electric power system asks for higher reliability epoxy (EP) insulators, thus it is important to seek effective methods improve the operating GIS insulators. On basis 110 kV insulator, this study studied aluminium oxide (Al2O3) settlement curing process and stress distribution horizontally laid GIS. Besides, risk coefficient was defined evaluate insulators by different (I–V). Some conclusions are shown below: Al2O3 causes insulator...
Traditional methods for developing new materials are no longer sufficient to meet the needs of human energy transition. Machine learning (ML) artificial intelligence (AI) and advancements have caused scientists realize that using AI/ML accelerate development batteries is a powerful potential tool. Although use certain fixed properties as descriptors act bridge between two separate disciplines AI chemistry has been widely investigated, many lack universality accuracy due understanding...
A comprehensive performance deviation analysis of different methods and their impacts during lab-scale solid oxide single cell experiments, along with recommendations for improving reliability.
Defect-rich carbon nanotubes (CNTs) for cyclohexane oxidation were systematically investigated.
Due to the low activation energy and high mobility of proton transfer, protonic ceramic cells (PCCs), including fuel (PCFCs) electrolysis (PCECs), working at...
Nanocarbon materials are promising catalysts of oxidative dehydrogenation (ODH) alkanes, but improving the alkene selectivity remains a challenge. A deep understanding and thorough identification oxygen species on nanocarbons strongly required for approaches to nanocarbon modification. Successful application iodometric titration in quantitative determination amount electrophilic surface carbon nanotubes has been performed this work. Electrophilic have identified as main culprits oxidation...
Galvanic corrosion behavior of 5083 alloy/H62 brass couple in 3.5 wt.% NaCl solution under 0, 0.2 and 0.4 T magnetic field were studied by microstructure observation, immersion test electrochemical measurement. The mixed potential theory was used to estimate the galvanic current density between alloy H62 brass. results indicated that can impede alloy, accelerate process effect on these two alloys increased as intensity rising. Magnetic reduce sensibility rate couple. With increase intensity,...
The Maxwell–Wagner model and bipolar charge transport both aim at describing the behaviours in dielectrics. performs well calculating polarisation current electric field distribution, but it is too macroscopic to describe microscopic of space charges. can simulate accumulation, cannot quantitatively relate with conductivities Considering shortages above two models, an improved model, named carrier dynamic equilibrium was proposed this study process low-density polyethylene/ethylene propylene...
Electric field optimization is a critical technique to ensure the compact structure and reliable operation for AC gas insulated power apparatus. To obtain more uniform electric distribution, this paper proposes concept of d-SFGM insulator, i.e., applying surface functionally graded material (SFGM) with designed thickness (d) distribution high permittivity along insulator surface. The magnetron sputtering was used fabricate d-uniform by depositing BaTiO <sub...
Abstract In recent years, the frequency of incidents related to safety electric vehicles (EVs) due lithium‐ion batteries has seen a troubling uptick, leading heightened focus on (LIBs) as critical area research. After thorough analysis, this study contends that root cause majority involving LIBs in field is predominantly linked reliability issues within battery products themselves. This argument offers more targeted perspective than broad discussion concerns LIBs. Reliability, context,...
In this work, a novel raft-like structure that combines noble metal nanoparticles (NPs) with an interconnected layer of hemispherical dielectric shell was fabricated and characterized. It discovered hybrid material can enhance the optoplasmonic interaction between plasmonic components, thereby improving sensing performance in surface-enhanced Raman spectroscopy (SERS). Varied geometric parameters raft, including inner diameter thickness shell, were attempted analyzed through numerical...
Ultra-low noise is a critical component in the design of high-precision sensor front-ends. We introduced differential phase-sensitive detection (d-PSD) to mitigate both multiplicative and additive optical sensors, aiming for an enhanced performance cost-effectiveness. The d-PSD combines capacitive transimpedance amplifier (C-TIA), delta–sigma analog-to-digital converter (ΔΣ-ADC), software-based lock-in (s-LIA). first two components utilize DDC112 (a dual current input 20-bit ADC) minimal...
