In this article, the effect of the addition of graphene oxide (GO) and reduced graphene oxide (rGO) on the mechanical properties, thermal stability, and electrical conductivity of polyvinyl alcohol (PVA) has been investigated. Different weight percentages of nanofillers ranging from 0.5 to 5 wt% have been combined with PVA. The ultrasonic technique has been applied to disperse nanofillers in the PVA...
The use of lithium manganese oxides in rechargeable lithium ion batteries has been stimulated due to their low cost and environmental compatibility. Especially, the interest of scientists concerns the oxide of the stable, spinel structured LiMn2O4. In the present work, this compound has been synthesized by three different methods viz., solid state reaction, modified sol–gel, and microwave hydrothermal...
