Temperature-sensitive wet granular matter — •Christoph Gögelein, Martin Brinkmann, Matthias Schröter, and Stephan Herminghaus — MPI für Dynamik und Selbstorganisation, Bunsenstr. 10, 37073 Göttingen

We present our recent experimental studies on the temperature-induced formation of capillary bridges in granular matter. We will demonstrate that we can precisely tune the bridge size and force by immersing our glass spheres in a binary liquid mixture [1]. Furthermore, we will discuss the effect of capillary bridges on random sphere packing's using a fluidized bed setup.
