A group of researchers from the Institute of Physics, together with an international team, studied the dynamics of water molecules in beryl crystals. As reported in their recent article in Nature Communications, they succeeded in proving for the first time that, at low temperatures, these localized water molecules tend to align, exhibiting so-called incipient ferroelectricity.

A team of researchers from the Institute of Physics and Institute of Thermomechanics of the Czech Academy of Sciences (CAS) recently published a study in the Science journal, which for the first time explained the mesomechanics of localized deformation in tensioned wire. Unlike other materials which deform homogenously, when NiTi wire is being stretched inelastic deformation proceeds via propagation of macroscopic transformation fronts separating transformed and untransformed regions.
