A novel measurement technique has been developed to visualize the fluid flow and distribution within two droplets levitated and coalesced in space using fluorescence-emitting particles. This technique ...

Researchers have shown that the injection of a thin or low-viscosity fluid into a much more viscous fluid (think of water spurting into molasses) will cause the two fluids to mix very quickly via a ...

Tsukuba, Japan—Generally, handling liquids requires containers. However, ultrasound technology can create a "lab-on-a-drop," an ultracompact testing environment, where multiple liquid droplets of ...
