General view of the synthesis of YF3 NPs and NP deposition on a surface by sonochemistry.
Notes: YF3 (black stars) is formed under ultrasonic irradiation (red waves). Microjets (blue arrows) are formed after the collapse of the acoustic bubble near the catheter wall and eject the NPs to create a YF3 NP coating.
Abbreviations: NP, nanoparticle; YF3, yttrium fluoride.
