Controlled drop generation via ligament extraction from a static or vibrating liquid bath
Johnathan Hoggarth, Daniel M. Harris, John W. M. Bush +1
We introduce a simple method for generating droplets at the surface of a liquid bath by rapidly stretching a liquid ligament with a spring-loaded cylindrical probe. By varying the…

Clogging of cohesive particles in a two-dimensional hopper
Johnathan Hoggarth, Pablo E. Illing, Eric R. Weeks +1
We study clogging of cohesive particles in a 2D hopper with experiments and simulations. The system consists of buoyant, monodisperse oil droplets in an aqueous solution, where the…

Simple Method for the Direct Measurement of Cohesive Forces Between Microscopic Particles
Johnathan Hoggarth, Kari Dalnoki-Veress
We present a simple and inexpensive method for measuring weak cohesive interactions. This technique is applied to the specific case of oil droplets with a depletion interaction, di…
