Top: absorption of cyclohexane by BN aerogel. Cyclohexane is stained with Sudan II red dye and is floating on water. Bottom: reuse of the aerogel after burning in air.
BN nanotubes are flame resistant, as shown in this comparative test of airplanes made of cellulose, carbon buckypaper and BN nanotube buckypaper.
