Key Points

Low-frequency sound effectively drives crystallisation of distinct solid forms, enhancing material properties.
The study utilizes a home-made apparatus, examining multiple organic compounds under controlled conditions.
Observational analysis shows the influence of sound frequency on the crystallisation process in solutions.
This approach may enable novel methods in materials science, indicating further exploration for practical applications.

Abstract

We show that low-frequency audible sound is able to drive the crystallisation of distinct solid forms of organic compounds in solution crystallisation. Using a home-made apparatus, suspended or mechanically coupled...
