High-precision control of nanoparticles for digital applications

For the first time ever, researchers have succeeded in creating arrangements of colloids – tiny particles suspended in a solution – and, importantly, they have managed to control their motion with high precision and speed. ...

The physics of salad dressing

Researchers at the University of Tokyo have shown that in phase separation in liquids, as is seen when oil and water separate, occurs as a result of the ordered motion of droplets. Initially, a great number of small droplets ...

Scientists prove possibility of 'impossible' dust transition in turbulent flow

Researchers from MIPT and the Weizmann Institute of Science (Israel) have predicted the possibility of negative turbophoresis, a phenomenon where impurity particles inside a turbulent flow move in an "impossible" direction. ...
