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 ...

A group of physicists came up with a way to stir up a liquid in a microchannel. Physicists managed to find a sophisticated solution to the problem based on the use of superhydrophobic surfaces. A lot ...

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 ...

The researchers have shown that the formation of these graphene particles is governed by a complex interplay between different forces such as viscosity, surface tension, inertia and electrostatics.
