Prof. Rocco Lupoi and Prof. Shuo Yin have recently published a paper which solves a long-standing mystery on the formation of vortex-like patterns during the cold spray process. The work, which was undertaken with collaborators from China, Czech Republic and the US, was published on the 30th of December, explains how the patterns are a result of severe plastic deformation that occurs when particles hit the deposition surface.

A longer summation of the work, including comments by Prof. Lupoi and Prof. Yin, can be found on the TCD website here.
