Fourth generation storage ring light sources enabled by multibend achromat lattices and high-gradient magnets can reach unprecedented photon brightness.In this study, we show that, through the two-frequency crab cavity scheme, such machines also offer a unique opportunity to produce intense short x-ray pulses that are ideal for time-resolved user e
A thermal-electric invisibility cloaking is designed by a nonlinear transformation, which can guide both electric current and heat flux around the concealed region and restore their original diffusion directions.Compared with previous thermal-electric cloaks designed by linear transformation, the proposed thermal-electric cloak by nonlinear transfo
In order to meet the demand of adjustable ozone concentration and reduce energy consumption, a new submerged ozone generator was designed.The nozzle, tzone ball reaction chamber and electrode plate were studied and optimized.The mechanical structure design of the device was completed.The electrical circuit model was built by Matlab/Simulink, the de
