Sonochemical hydrolysis of Ga³⁺ ions: Synthesis of scroll-like cylindrical nanoparticles of gallium oxide hydroxide

The sonochemical reaction of an aqueous solution of GaCl₃ led to the formation of gallium oxide hydroxide rolled up in a scroll-like layered structure to give cylinders 80-120 nm in diameter and 500-600 nm in length. Small amounts of metallic Ga were incorporated with these tubes. A mechanism for this reaction has been suggested where the reaction takes place in a shell surrounding the collapsing bubble.
