Topographic Control of Order in Quasi-2D Granular Phase Transitions (2021)
Journal Article
Downs, J. G., Smith, N. D., Mandadapu, K. K., Garrahan, J. P., & Smith, M. I. (2021). Topographic Control of Order in Quasi-2D Granular Phase Transitions. Physical Review Letters, 127(26), Article 268002. https://doi.org/10.1103/PhysRevLett.127.268002

We experimentally investigate the nature of 2D phase transitions in a quasi-2D granular fluid. Using a surface decorated with periodically spaced dimples we observe interfacial tension between coexisting granular liquid and crystal phases. Measuremen...

ParticleTracker: a gui based particle tracking software (2021)
Journal Article
Smith, M. I., & Downs, J. G. (2021). ParticleTracker: a gui based particle tracking software. Journal of Open Source Software, 6(66), Article 3611. https://doi.org/10.21105/joss.03611

Tracking the motion of objects in a video is an important part of the analysis in a diverse range of subject disciplines (Meijering, 2012; Rahman, 2019; Rose, 2020). It enables one to automate the extraction of quantitative information about size, sh... Read More about ParticleTracker: a gui based particle tracking software.

Slip in adhesion tests of a Kaolin clay (2021)
Journal Article
Hayes, M. J., & Smith, M. I. (2021). Slip in adhesion tests of a Kaolin clay. European Physical Journal E, 44(8), Article 102. https://doi.org/10.1140/epje/s10189-021-00107-9

Adhesion tests were performed on concentrated suspensions of Kaolin clay. At low concentrations samples formed conical deposits on both the top and bottom plates with the central region narrowing to a filament before undergoing breakup. In contrast h...

Collision-enhanced friction of a bouncing ball on a rough vibrating surface (2021)
Journal Article
Smith, N. D., Swift, M. R., & Smith, M. I. (2021). Collision-enhanced friction of a bouncing ball on a rough vibrating surface. Scientific Reports, 11, Article 442. https://doi.org/10.1038/s41598-020-80067-w

We describe experiments and simulations to investigate the dynamics of a ball bouncing on a rough vibrating surface. Directly measuring the impulse due to each bounce we find that the frictional interaction with the surface is strongly enhanced near...
