In a mixture of two species of grains of equal size but different mass, placed in a vertically vibrated shallow box, there is spontaneous segregation. Once the system is at least partly segregated and clusters of the heavy particles have formed, there are sudden peaks of the horizontal kinetic energy of the heavy particles, that is otherwise small.

We describe the peeling of an elastomeric strip adhering to a glass plate through van der Waals interactions in the limit of a zero peeling angle. In contrast to classical studies that predict a saturation of the pulling force, in this lap test configuration the force continuously increases, while a sliding front propagates along the tape. The strip(More)
