Pressure makes best cooling

Phase transitions take place as heat (i.e., entropy) is exchanged between materials and the environment. When such processes are driven by pressure, the induced cooling effect is called the barocaloric effect, which is a ...

Color-changing sparks

Sparks are a fascinating phenomenon well-known from campfires, flint stones and electric sparklers and other pyrotechnic articles. Looking at sparks more closely reveals the limited colors in which they appear. Dark red-orange ...

A fascinating phase transition from one liquid state to another

A team at the University of Tokyo has described in unprecedented detail the rare phenomenon of liquid-to-liquid phase transitions in a pure substance. By showing how a liquid made of just one type of molecule can switch between ...

Decoding social media engagement with celebrities

Indian Prime Minister Narendra Modi engaged celebrities effectively on social media in the run-up to the 2014 general elections in India to raise his visibility and help his electoral ambitions, a new University of Michigan ...

In a new quantum simulator, light behaves like a magnet

Physicists at EPFL propose a new "quantum simulator": a laser-based device that can be used to study a wide range of quantum systems. Studying it, the researchers have found that photons can behave like magnetic dipoles at ...
