COLIS: an advanced light scattering apparatus for investigating the structure and dynamics of soft matter onboard the International Space Station
Alessandro Martinelli, Stefano Buzzaccaro, Quentin Galand +8
Colloidal Solids (COLIS) is a state-of-the-art light scattering setup developed for experiments onboard the International Space Station (ISS). COLIS allows for probing the structur…
What buoyancy really is. A Generalized Archimedes Principle for sedimentation and ultracentrifugation
Roberto Piazza, Stefano Buzzaccaro, Eleonora Secchi +1
Particle settling is a pervasive process in nature, and centrifugation is a much versatile separation technique. Yet, the results of settling and ultracentrifugation experiments of…
Equilibrium concentration profiles and sedimentation kinetics of colloidal gels under gravitational stress
Stefano Buzzaccaro, Eleonora Secchi, Giovanni Brambilla +2
We study the sedimentation of colloidal gels by using a combination of light scattering, polarimetry and video imaging. The asymptotic concentration profiles $φ(z,t\rightarrow \inf…
Highly nonlinear dynamics in a slowly sedimenting colloidal gel
Giovanni Brambilla, Stefano Buzzaccaro, R. Piazza +2
We use a combination of original light scattering techniques and particles with unique optical properties to investigate the behavior of suspensions of attractive colloids under gr…
