Optical extinction, refractive index, and multiple scattering for suspensions of interacting colloidal particles
Alberto Parola, Roberto Piazza, Vittorio Degiorgio
We provide a general microscopic theory of the scattering cross-section and of the refractive index for a system of interacting colloidal particles, exact at second order in the mo…
Optical correlation techniques for the investigation of colloidal systems
Roberto Piazza
This review aims to provide a simple introduction to the application of optical correlation methods in colloidal science. In particular, I plan to show that full appraisal of the i…
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…
The Classical Nature of Thermal Conduction in Nanofluids
Jacob Eapen, Roberto Rusconi, Roberto Piazza +1
Several new mechanisms have been hypothesized in the recent years to characterize the thermal conduction behavior in nanofluids. In this paper, we show that a large set of nanoflui…
Liquid-liquid phase separation of a surfactant-solubilized membrane protein
R. Piazza, M. Pierno, E. Vignati +4
The phase behavior of membrane proteins stems from a complex synergy with the amphiphilic molecules required for their solubilization. We show that ionization of a pH-sensitive sur…
