Inside most materials, little is moving. But a new "active nanocomposite" is teeming with motion: small particles connect or separate, thus changing the color of the entire material. It was made ...

The liquid state of matter is an intermediate phase between solid and gas. Like the particles of a solid, particles in a liquid are subject to intermolecular attraction; however, liquid particles ...

Find out what particle arrangements and movements are in solids, liquids, and gases in this BBC Bitesize KS3 physics guide.

Imagine a liquid that flows freely one moment, then stiffens into a near-solid the next, and then can switch back with a ...

Unlocking the secrets of oobleck—strange stuff that’s both liquid and solid Scientists tested hypothesis with dense suspensions of piezoelectric nanoparticles.

The term colloid describes a system consisting of one substance finely dispersed in another, normally a solvent. The size of particles found in a colloidal dispersion range between 1 and 1000 ...

Deformation wear – In solid impingement erosion, deformation wear is the erosive wear of a material related to the dissipation of kinetic energy of impact arising from the normal component of the ...

In a solid, these particles are packed closely together and are not free to move about within the substance.
