Biodiesel from Used Oil Roland Stout
Recently three papers have appeared in this Journal discussing the properties of biodiesel fuels and their production from biological oils, either new or used. We will frustrate students if we do not discuss why laboratory scale productions of biodiesel from used oil may produce significant amounts of emulsion.

Viscosity of Common Seed and Vegetable Oils C. Wes Fountain, Jeanne Jennings, Cheryl K. McKie, Patrice Oakman, Monty L. Fetterolf
A viscosity experiment is presented here that is designed around common seed and vegetable oils. With the importance of viscosity to foodstuffs and the importance of fatty acids to nutrition, an experiment using these common, recognizable oils has broad appeal.
