Hypothesis: Ellipsoidal particles confined at liquid interfaces exhibit complex self-assembly due to quadrupolar capillary interactions, favouring either tip-to-tip or side-to-side configurations. However, predicting and controlling which structure f... Read More about Self-assembly of defined core–shell ellipsoidal particles at liquid interfaces.

Programmable 2D materials through shape-controlled capillary forces (2024)
Journal Article
Eatson, J., Morgan, S., Horozov, T. S., & Buzza, M. D. (2024). Programmable 2D materials through shape-controlled capillary forces. Proceedings of the National Academy of Sciences of the United States of America, 121(35), Article e2401134121. https://doi.org/10.1073/pnas.2401134121

In recent years, self-assembly has emerged as a powerful tool for fabricating functional materials. Since self-assembly is fundamentally determined by the particle interactions in the system, if we can gain full control over these interactions, it wo...
