We have studied the radio frequency dielectric response of a system consisting of separate polar water molecules periodically arranged in nanocages formed by the crystal lattice of the gemstone beryl. Below

Behavior of individual molecules of normal and heavy water in beryl single crystals was studied by $^1$H and $^2$H nuclear magnetic resonance spectroscopy. From temperature dependences of the spectra we deduce that type-I water molecules embedded in

An accurate X-ray diffraction study of cordierite mineral, the simplified chemical formula of which is Mg2Al4Si5O18, is performed. The main octahedral position contains magnesium, iron, and aluminum ions, as well as traces of manganese. Alkaline cati

A quantitative analysis of the evolution of a spherical surface artificially prepared from a potassium alum single-crystal during its regeneration is carried out in real growth experiments. The results are compared with the results of the numerical s

This paper presents a possible mechanism forming crystals with antiskeletal morphology due to their regeneration after partial dissolution. Consideration is carried out by numerical 2D-simulation of the coordinate zone evolution of a single crystal b

The potential possibility of intergrowth of two bulk crystals to single crystal was demonstrated on the example of beryl, Be3Al2Si6O18, growing under hydrothermal conditions. The result has practical importance because it allows increase of the yield

This study explores the fine structural details of the boundaries between the growth micro-sectors in a ruby crystal grown hydrothermally on a nonsingularly oriented (01) seed. The samples were examined using IR-spectroscopy and HRTEM-analysis, demon

We have studied terahertz and radio-frequency dielectric response of single water molecules periodically arranged in nano-cages formed by the crystal lattice of beryl. Below ≈20 K, quantum effects start to dominate the properties of the H2O dipolar

Water is characterized by large molecular electric dipole moments and strong interactions between molecules; however, hydrogen bonds screen the dipole–dipole coupling and suppress the ferroelectric order. The situation changes drastically when wate
