In this project, we propose to use thermodynamic multiscale modeling, finite element simulations, and experiments to study how the dynamics of the bubble, driven by 10-100Hz vertical vibrations, locally modifies the rheological properties of the associative polymers, e.g., by triggering shear-thinning, viscoelastic stresses and strain softening of the material. We will then harness the local changes of rheological properties to control the rising speed of bubbles of a given radius. Finally we will study how changing the mechanical driving force and the rheological parameters enables the control of the bubble distribution inside solutions of associative polymers. 

Micro- and nanoscale robotic platforms have captured the attention of researchers due to their remarkable ability to perform tailored tasks with unparalleled precision and minimal invasiveness. These robots hold great promise, with the potential to revolutionize fields ranging from biomedicine to environmental applications. Ranging from catalytic to externally actuated robots (i.e., magnetic, light), these robots offer the possibility of targeted drug delivery and enhanced reactivity due to their autonomous motion.

In the GREENS project, we aim to implement the 5R (Reduce, Reuse, Rot, Recycle, Refuse) principle from the manufacturing to the final implementation and removal of nano/micro-robotic platforms, always accounting for the sustainability of the overall process to minimize the impact of fabricating/applying them to the environment.
