Active particles are analogs of microorganisms in that they locally dissipate energy to propel in low Reynolds number fluids. However, most active particles lack the ability to undergo controlled ...

Imagine a liquid that flows freely one moment, then stiffens into a near-solid the next, and then can switch back with a simple change in temperature. Researchers at the University of Chicago Pritzker ...

Active microparticles are heavily investigated for use in microrobotics 1, biomedicine 2, solute capture 3, and functional materials fabrication 4 due to their ability to harness energy from their ...

Researchers from the U.S. Department of Energy's (DOE) Brookhaven National Laboratory have discovered that the size of catalytic nanoparticles determines how their shape and structure transform during ...

In a twist on conventional wisdom, researchers have discovered that in ocean-like fluids with changing density, tiny porous particles can sink faster than larger ones, thanks to how they absorb salt.

Continuous evolution of Fermi arcs and the achieved electromagnetic pulling force. a, Schematic showing how Fermi arcs can be adjusted by varying the thickness of an air layer sandwiched between two ...

A tightly compressed bundle of office staples can behave in a surprising way. Even though it is made of many separate pieces, the tangled mass can be ...
