Bubbles can be useful tools for microscopic robots, helping them move, steer, create flows of liquid and perform other ...

Researchers at Cornell University have developed a chip-based system that creates and controls hydrogen ...

If you’ve ever whacked the bottom of a ketchup bottle to get that tasty tomato goop flowing, you’ve put some serious physics to work. Ketchup is a non-Newtonian fluid. So are toothpaste, yogurt, ...

Blood may be thicker than water, but in a narrow enough tube, both liquids flow like treacle. This sluggish behaviour arises because, as you reduce the size of the channel, friction between the liquid ...

Computer modeling shows that surprisingly large regions can trap particles carried by a fluid that is moving steadily through a pipe junction. Anchored in place. A computer model of particles carried ...

A zigzag arrangement that appears spontaneously in a collection of magnetic particles and some other colloids is explained by the fluid flow around each particle. Magnetic particles in an oscillating ...
