What is it about?
Conceptually similar to our macroscopic world where objects such as cars exhibit an aerodynamic drag that depends on the spatial measurements and the shape, the friction of small particles dispersed in a fluid is also shape-dependent. In this direct continuation of our recent work J. Chem. Phys. 155, 104113 (2021), we compute empirical equations for the diffusion coefficients (i.e., the thermal energy of the system divided by the friction coefficient) of nano- or micro-sized linear trimer particles, which consist of a linear string of three overlapping spheres.

Why is it important?
Our easy to apply formulas for the diffusion coefficients can be used to corroborate future experiments studying trimer particles. Additionally, they can be used to facilitate the design of new colloidal computer simulations, which address the motion of trimer particles with arbitrary aspect ratios.
