ABSTRACT

---

     Ultrasound may be used to create high energy chemistry by means of acoustic cavitation (a process of formation, growth, and implosion of bubbles in a liquid).  During the collapse of these cavitation bubbles intense heating and high pressure areas are generated, reaching values near 5000 k and 500 atm respectively.  These two parameters are necessary in creating chemical reactions.  Since acoustic cavitation deals with bubbles in a liquid, the bubbles shape and spherical compression are effected by buoyancy.  We will be designing a sonochemical apparatus to observe the effects that zero gravity has on the formation of sonochemical products such as increase yield, and altered geometric properties of nano-sized metallic particles.
