Delayed Gravitational Collapse of Attractive Colloidal Suspensions

Autor: Torre, Kim William, de Graaf, Joost

Colloidal gels have strong industrial relevance as they can behave liquid- and solid-like. The latter allows them to support the buoyant weight against gravity. However, the system is intrinsically out-of-equilibrium, which means that the colloids mu

Hydrodynamic Lubrication in Colloidal Gels

Autor: Torre, Kim William, de Graaf, Joost

Colloidal gels are elasto-plastic materials composed of an out-of-equilibrium, self-assembled network of micron-sized (solid) particles suspended in a fluid. Recent work has shown that far-field hydrodynamic interactions do not change gel structure,

Hydrodynamic Stability Criterion for Colloidal Gelation under Gravity

Autor: de Graaf, Joost, Torre, Kim William, Poon, Wilson C. K., Hermes, Michiel

Attractive colloids diffuse and aggregate to form gels, solid-like particle networks suspended in a fluid. Gravity is known to strongly impact the stability of gels once they are formed. However, its effect on the process of gel formation has seldom

Structuring Colloidal Gels via Micro-Bubble Oscillations

Autor: Torre, Kim William, de Graaf, Joost

Locally (re)structuring colloidal gels $\unicode{x2013}$ micron-sized particles forming a connected network with arrested dynamics $\unicode{x2013}$ enables precise tuning of the micromechanical and -rheological properties of the system. A recent exp
