Introduction For many potential mobile robot applications, current power supply technology (such as the lithium ion battery technology) is in fact a key limiting factor due to its low energy density. Solid oxide fuel cells (SOFCs) are a promising alt

SnO2/Fe2O3nanocomposites were successfully synthesized by microwave heating. SEM-EDX and XRD analyses and Raman spectroscopy revealed that nanosized SnO2was deposited on rod-shaped α-Fe2O3crystals. The SnO2/Fe2O3nanocomposites worked as a rechargeab

A porous titania was synthesized by spray-drying of titania nanosheets exfoliated by (C4H9)4NOH. Nitrogen adsorption-desorption isotherms showed that the porous titania has a mesoporous structure composed of slit-shaped pores. The porous titania acte

Ultrafine α-Fe2O3 nanoparticles with an extremely narrow distribution were synthesized by microwave heating. Transmission electron microscopy (TEM) images showed that most primary particles have ellipsoid shapes, and the average diameter of the prim
