Self-steering particles go with the flow

MIT chemical engineers have designed tiny particles that can "steer" themselves along preprogrammed trajectories and align themselves to flow through the center of a microchannel, making it possible to control the particles' ...

Osmosis in colloidal suspensions

(PhysOrg.com) -- It is very difficult to overestimate the importance of colloidal suspensions. Besides being an integral part of our everyday life (food, cosmetics, drugs), they also serve as an excellent model system for ...

A model for describing the hydrodynamics of crowds

Precise simulations of the movement and behavior of crowds can be vital to the production of digital sequences or the creation of large structures for crowd management. However, the ability to quantitatively predict the collective ...

Engineer Discovers Why Particles Like Flour Disperse on Liquids

(PhysOrg.com) -- Even if you are not a cook, you might have wondered why a pinch of flour (or any small particles) thrown into a bowl of water will disperse in a dramatic fashion, radiating outward as if it was exploding. ...
