Tiny magnets mimic steam, water and ice

Researchers at the Paul Scherrer Institute (PSI) created a synthetic material out of 1 billion tiny magnets. Astonishingly, it now appears that the magnetic properties of this so-called metamaterial change with the temperature, ...

Novel theory of entropy may solve materials design issues

A challenge in materials design is that in both natural and manmade materials, volume sometimes decreases, or increases, with increasing temperature. While there are mechanical explanations for this phenomenon for some specific ...

Collapse of the universe is closer than ever before

Maybe it happens tomorrow. Maybe in a billion years. Physicists have long predicted that the universe may one day collapse, and that everything in it will be compressed to a small hard ball. New calculations from physicists ...

Tetrahedra may explain water's uniqueness

Researchers at the Institute of Industrial Science at the University of Tokyo sifted through experimental data to probe the possibility that supercooled water has a liquid-to-liquid phase transition between disordered and ...

Phase transition

A phase transition is a natural physical process. It has the characteristic of taking a given medium with given properties and transforming some or all of that medium, into a new medium with new properties. Phase transitions occur frequently and are found everywhere in the natural world. Some engineering techniques exploit certain types of phase transition.

In thermodynamics, a phase transition is the transformation of a thermodynamic system from one phase to another.

At a phase transition point, physical properties may undergo abrupt change: for instance, the volume of the two phases may be vastly different as is illustrated by the boiling of liquid water to form steam.

The term is most commonly used to describe transitions between solid, liquid and gaseous states of matter, in rare cases including plasma.
