Hello everyone, and welcome back to my blog. As I have mentioned before, I plan on researching the specifics of the experimental set-up I intend to work with in college in the coming weeks. Recently, I’ve been looking into how focused ultrasound actually breaks down polymers in a solution. I’ve learned that there are two main forces at play: thermodynamic forces and hydrodynamic forces. Ultrasound can induce rapid fluid movement when fired at a solution. This movement often results in higher fluid temperature, which can independently depolymerize a substance. Additionally, high-frequency ultrasonic waves create hydrodynamic shear forces that can break down a polymer mechanically. It’s satisfying to finally have an in-depth understanding of the mechanisms I was supposed to test. I look forward to doing more literature review and sharing what I learned with you all. Stay safe, everyone!
