While quasi-Newtonian complex fluids under steady-state flow, dense non-Brownian suspensions exhibit complex "macro-fragile" behaviors under varying flow conditions, as revealed by abrupt shear inversions (reversals). Here, we introduce an experimental setup to systematically explore their macro-fragile response to shear rotations, where one...

Dense non-Brownian suspensions exhibit a spectacular and abrupt drop in viscosity under change of shear direction, as revealed by shear inversions (reversals) or orthogonal superposition. Here, we introduce an experimental setup to systematically explore their response to shear rotations, where one suddenly rotates the principal axes of shear...

As part of their third-year general chemistry program, students at the University of the Côte d'Azur are taught the basics of radioactivity. The view that third-year university students have of the periodic Table of the Elements is often reduced because it ignores the vast majority of isotopes. As part of this program, a practicum devoted to...
