Active particles can form two-dimensional solids that are different from those formed by nonmotile particles, showing long-range crystalline order accompanied by giant spontaneous deformations. Figure ...

Even though it is the same water, why does its form change?When you heat ice, it becomes water.When you heat it further, it ...

New research published in the Proceedings of the National Academy of Sciences describes how external forces drive the rearrangement of individual particles and shape microlevel structures in ...

Quasiparticles arise from the complex interaction of many particles in solids; for example, we describe lattice vibrations in crystals as phonons. Fractons are exotic quasiparticles that occur at the ...

Researchers have detailed the physics behind a phenomenon that allows them to create spin in liquid droplets using ultrasound waves, which concentrates solid particles suspended in the liquid. The ...

A pump protection assembly has proven to safeguard pumps from sand and extend ESP run life in unconventional wells. This solution controls flowback from frac sand and other solids that can lead to ...
