The diamond Schottky theory needs to be further improved before exertising its full advantages, especially in terms of the physical properties of the diamond surface and the interface between metals and diamond. In our previous work, we experimentally verified that the oxygen terminal with a...

Although peroxymonosulfate (PMS) coupling with ultrasonic piezo-catalysis (PE) or electrolysis (E) exhibited synergy of organics degradation by generating more reactive oxidative species (ROS), the relatively high energy consumption restricted their application. Hydro-energy, as a clean energy...

Voltage sag state estimation based on a limited number of accessible monitors is essential to assessing the cost balance between investments in mitigation device and disruption cost saved. In this paper, a deep learning method based on Bidirectional WaveNet for voltage sag state estimation via...
