## Abstract CoFe~2~O~4~ hollow spheres with sizes ranging from 600 nm to 1 ΞΌm were prepared through hydrothermal treatment of an aqueous solution containing glucose, ammonium iron(II) sulfate hexahydrate [(NH~4~)~2~Fe(SO~4~)~2~Β·6H~2~O], and cobalt(II) sulfate heptahydrate [CoSO~4~Β·7H~2~O], followed
**Nickel sulfide uniform hollow spheres** (see scanning electron microscopy image, Figure) have been successfully synthesized by Ξ³βirradiation of a PMMAβCS~2~βethanol aqueous solution that contains NiSO~4~Β·6H~2~O at room temperature. Calculation shows that the diameter of the NiS hollow spheres is 5
