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 ...

Recent reports that macroscopic vortex flows can discriminate between chiral molecules or their assemblies sparked considerable scientific interest both for their implications to separations ...

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 ...

Unlike civil aviation, where aircraft fly relatively steadily and generate lift at low angles of attack, military aircraft are often required to perform extreme manoeuvres. These manoeuvres can push ...

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 ...

Vortex flowmeters have been available on the market since the late 1960s, and the number of applications they are used for has steadily increased. Over that same time, reliability has also increased, ...

It's well-known by now that the coronavirus can spread from person to person via respiratory droplets. But droplets aren't the only bodily fluid that the virus can travel in: Multiple studies have ...
