A phenomenon that is well known from chaos theory was observed in a material for the first time ever. A structural transition in the ferroelastic material barium titanate, caused by an increase or ...

A research group from the U.S. Department of Energy’s Oak Ridge National Laboratory has conducted a study, which shows that hybrid organic–inorganic perovskite is ferroelastic, and not ferroelectric ...

First proposed over thirty years ago, negative refractive index materials bend light in the opposite direction to ordinary materials. However, they were not demonstrated experimentally until 2000.

A phenomenon that is well known from chaos theory was observed in a material for the first time ever, by scientists from the University of Groningen, the Netherlands. A structural transition in the ...
