An everyday occurrence spotted when we turn on the tap to brush our teeth has baffled engineers for centuries—why does the water splay when it hits the sink before it heads down the plughole?
Swimming bacteria can reduce the viscosity of ordinary liquids like water and make them flow more easily, sometimes down to the point where the viscosity becomes zero: the flow is then frictionless.
Atomizing liquids is vital to fuel-air mixing. Using oscillating liquid streams, breakup and drop formation can be improved compared to common straight jets. But the many dynamic interactions make it difficult for scientists ...
Researchers from Tokyo Metropolitan University have observed the formation of holes that move by themselves in droplets of ionic liquids (IL) sitting inside water-ethanol mixtures. This complex phenomenon is driven by an ...
Blood spatter can provide a lot of informanulltion to an investigator at a crime scene. Unfortunately, current methods do not tell the whole story. UIC Distinguished Professor Alexander Yarin and his colleagues have shown ...
Many fish species swim in schools and birds fly in flocks. Such collective behaviour must arise from the interactions between the animals. How it works was largely unclear. Now, two Wageningen-researchers provide important ...
You may never have heard of the capillary effect, but it's something you deal with every time you wipe up a spill or put flowers in water. Wouter van der Wijngaart has spent most of his life contemplating this phenomenon, ...
Each time a blood vessel splits into smaller vessels, red blood cells (RBCs) are presented with the same decision: Take the left capillary or the right. While one might think RBCs would divide evenly at every fork in the ...
