Uniform-sized monodisperse cerium dioxide nanocubes with 20–120nm edge lengths can be synthesized by an inexpensive microwave-assisted method. This is based on the oxidation and then decomposition of cerium (III) nitrate aqueous solution under a basic environment. The high energy emitted by microwave irradiation at a short time can promote the reaction and the crystallization process simultaneously...
The structure and design method of an electric drive system for high power applications are presented. A multiphase permanent magnet brushless dc motor (PMBDCM) fed by a current source inverter (CSI) with thyristors acts as the kernel of the proposed electric drive system. Therefore, the system takes on advantages of both those two devices. The PMBDCM is simulated by FEM. The performance of power...
