Ultrasonic agitation is a proven method for breaking down layered materials such as MoS2 into single or few layer nanoparticles. In this experiment, MoS2 powder is sonicated in isopropanol for an extended period of time in an attempt to create particles of the smallest possible size. As expected, the process yielded a significant quantity of nanoscale MoS2 in the form of finite layer sheets with lateral dimensions as small as a few tens of nanometers.

- The research focuses on the electronic structure of multi-walled carbon fullerenes, or carbon onions, which remain largely unexplored due to high computational costs and unknown crystal structures.
- Experimental methods involved creating carbon onions through ultrasonic agitation and depositing them on graphite, revealing their ellipsoidal shape and consistent features with graphite, plus some showing semiconducting properties.
- The study finds that most carbon onion configurations are metallic, with a few being semiconductors, influenced by their non-metallic layers and minimal interlayer interaction affecting the overall electronic properties.
