Solids, liquids and gases. In a solid like this brick, the particles are regularly arranged touching their neighbours and move only by vibrating. This explains why solids have a fixed shape. In a ...

We explore Supercritical Fluids and how being "in the between" is their superpower. Supercritical Fluids are one the strangest states of matter and yet they are found everywhere from Decaf Coffee, to ...

Scientists have observed transitions into and out of an exotic state of matter found between liquid and solid in 2-D materials (Sci. Rep. 2021, DOI: 10.1038/s41598-020-80082-x). The hexatic phase ...

THE tenets of physics can seem carved in stone. The speed of light is a constant. There are four fundamental forces. Theoretically, rules like these are open to revision. But new contenders had better ...

Theoretical modelling explores the movement of atoms within a liquid nanodroplet of platinum that is confined inside a defect in a carbon support. The colours represent the mobility of the atoms: ...

Dash a few drops of water onto a very hot, sizzling skillet and they’ll levitate, sliding around the pan with wild abandon. Physicists at Virginia Tech have discovered that this can also be achieved ...
