This paper investigates the effects of processing and equipment parameters of a ribbon blender (i.e. loading method of lubricant, fill level, blade speed and blade design) on magnesium stearate homogeneity. A core sampling technique is used to obtain

Parametrically excited surface waves (Faraday waves) are studied near the threshold for breaking. The breaking state ejects droplets from wave peaks when the applied forcing exceeds an acceleration threshold. The rate of breaking events approaches ze

Strongly driven waves break and lead to local singularities. Parametrically forced standing waves (Faraday waves) may break leading to a local power-law divergence on the free surface. We experimentally explore this state for its local structure, tim

We examine free surface wave singularities that show a violent focusing of energy. Periodic, modulated, and frequency locked wave states lead to a state with fluid spikes. When the excitation of free surface waves exceeds a well defined threshold, th

Surface waves produced by parametric excitation experience a transition between simply connected waves and droplet-ejecting waves when the applied forcing exceeds a threshold level. Our measurements on a number of different fluids indicate that low-v

Surface wave experiments confirm predictions of a threshold amplitude for droplet ejection. Droplet ejection and spray originate from highly focused surface singularities in the simplest states. The threshold is found to be dependent on forcing frequ
