The results show that the obtained nanoscale zero valent iron particles are mostly in spherical shape with less than 100 nm in size. The acid fuchsine can be removed by nanoscale zero valent iron particles efficiently. The efficiency of removing acid fuchsine from solution is increased with increasing temperature and the dosage of nanoscale zero valent iron particles and decreasing initial concentration of acid fuchsine. The mechanism of removing acid fuchsine by nanoscale zero valent iron particles may include dual functions of absorption and degradation, and the degradation may play a major role in the reaction.

A novel zero-voltage and zero-current resonant pole soft-switching inverter was proposed to achieve zero- voltage and zero-current switching simultaneously when main power devices turn-on and turn-off. Therefore, turn-on capacitive losses could be reduced for devices which the intrinsic capacitor value cannot be neglected. Additionally losses caused by the tail current can also be reduced, when IGBTs are used as main switches.
