News: Theory and Simulation

For undergraduates in the engineering school, summer often means a chance to apply their learning in new ways, whether conducting field research, working in industry or volunteering abroad. Last summer, with the COVID-19 pandemic disrupting many of these plans, some students’ research projects took them in unexpected directions.

Water, so ordinary and so essential to life, acts in ways that are quite puzzling to scientists. For example, why is ice less dense than water, floating rather than sinking the way other liquids do when they freeze?

In a development offering great promise for additive manufacturing, Princeton University researchers have created a method to precisely create droplets using a jet of liquid. The technique allows manufacturers to quickly generate drops of material, finely control their size and locate them within a 3D space.
