Manipulating large numbers of a variety of particles/wires is essential for many lab-on-a-chip technologies. Here we generate a planar array of optofluidic vortices with photothermal gradients from an ...

Urban drainage systems have increasingly incorporated vortex flow mechanisms to efficiently dissipate hydraulic energy while minimising structural damage and regulating discharge. Vortex drop shafts ...

When a tiny droplet of cold fluid mixes with a high-temperature solid particle, a vapor layer forms between them, and they never actually touch. Ohio State University researchers have performed the ...

Japanese scientists at Tokyo University of Agriculture and Technology (TUAT), Teikyo University of Science, and Juntendo University have found -- in animal studies -- a close relationship between ...

It may sound unbelievable, but new research suggests that instead of being featureless, dark matter could actually behave like a cosmic superfluid, forming swirling vortex lines and stable rotating ...
