Chemical Solution-Based Synthesis of Nano-Magnesium Oxide Dielectrics,lue since the filler and the matrix were the same material. The result also revealed that the dielectrics with 1 wt% filler loading has good electrical properties while dielectrics 2 wt% filler loading was very uniform and compact.

Enhancement of Nanocomposite for Humidity Sensor Application,nge of 40–90%RH. ZnO/SnO. composite nanorods performed the highest sensitivity with 265 ratio compared to the ZnO agglomerate nanoparticle and SnO. nanorod. The response and recovery time for ZnO/SnO. composite nanorods were 227 s and 34 s respectively.

Nanozeolite Produced by Wet Milling at Different Milling Time,eolite particle may be reduced by mechanical treatment such as ball milling or grinding in order to get smaller particles. In this chapter, the effect of milling time on particle size and surface morphology of Zeolite were investigated by a few designed experiments in aqueous environment. Zeta-sizer
