This document discusses rheology results from mixtures of hard and soft spheres. Specifically, it examines systems containing silica nanoparticles coated with polyethylene glycol (PEG) chains of various molecular weights mixed with star polymers in squalene. The rheological properties, including storage and loss modulus and tan delta, were measured for mixtures with varying ratios and PEG chain lengths. Increasing the concentration of hard silica spheres was found to first increase then decrease the relative height of the loss modulus. It also caused the storage modulus to rise and tan delta to initially fall then rise again, indicating a transition from jammed to unjammed behavior with more hard spheres added.
