Microgravity experiments on the collisional behavior of Saturnian ring particles
TL;DR: In this article, the authors present results of two novel experimental methods to investigate the collisional behavior of individual macroscopic icy bodies in the microgravity environments of parabolic flights and the Bremen drop tower facility.

Submillimetre-sized dust aggregate collision and growth properties
TL;DR: In this article, the surface energy and tensile strength of sub-mm-sized aggregates composed of protoplanetary dust analogue material are measured, including the statistical threshold velocity between sticking and bouncing, their surface energy, and their surface strength within aggregate clusters.

Collisions of small ice particles under microgravity conditions
TL;DR: In this article, a parabolic flight campaign was used to investigate the impact of small ice particles on the solid material of a protoplanetary disk by a process of dust aggregation, and the results showed that up to 17% of the energy of the particles before the collision was converted into rotational energy.

Normal Collisions of Spheres: A Literature Survey on Available Experiments
TL;DR: In this paper, the relation between the normal coefficient of restitution e and the incident velocity v is compared between experiments and models, and a broad comparison of experiments and model is drawn.
