“…can be the general phenomenon. The description of the reversal melting was first proposed by Rein and Demus (RD) (Rein and Demus, 1993;Demus and Pelzl, 1988) and subsequently by Kechin (K) (Kechin, 1995;Kechin 2001):…”

“…It is notable, that already a century ago it was indicated that the reversal melting (Tammann, 1903), although it can be hidden in the negative pressures domain or its emergence can be stopped by a phase transition. The description of the reversal melting phenomenon was first clearly proposed by Rein and Demus (RD) (Demus and Pelzl, 1988;Rein and Demus, 1992) and subsequently by Kechin (K) (Kechin, 1995(Kechin, , 2001:…”

The ways of portrayal of the pressure evolution of the glass temperature (T g ) beyond the dominated Simon-Glatzel-like pattern are discussed. This includes the possible common description of T g (P) dependences in systems described by dT g /dP > 0 and dT g /dP < 0. The latter can be associated with the maximum of T g (P) curve hidden in the negative pressures domain. The issue of volume and density changes along the vitrification curve is also discussed. Finally, the universal pattern of vitrification associated with the crossover from the low density (isotropic stretching) to the high density (isotropic compression) systems is proposed. Hypothetically, it may obey any glass former, from molecular liquids to colloids.

“…Such behavior is counter-intuitive, as temperature and other system parameters typically act one-sidedly, building up or destroying a given type of order. Observations of reentrant transitions date back to the 19th century [4], but new instances keep being discovered [5] and are no less intriguing.…”

Oxyapatites A10(GeO4)6O2 (A – alkaline, rare‐earth elements) are considered promising materials for applications in solid‐state lighting and non‐contact thermometry. The temperature dynamics of the oxygen sublattice have a crucial influence on the luminescent properties of these optical hosts. Here, the structural evolution with temperature of germanates with the general formula ALa9(GeO4)6O2 (A – Li, Na, K, Rb) is investigated, using X‐ray and neutron powder diffraction methods. These compounds crystallize in space‐group P63/m. NPD experiments helped to determine the oxygen and alkaline metal positions. Thermally‐induced reentrant structural transitions relating to the oxygen in the apatite channel are discovered for the first time. In the example of Eu‐doped RbLa9(GeO4)6O2 and KLa9(GeO4)6O2, it is demonstrated that the luminescence of the Eu3+ ion is influenced by small changes in the crystal structure.
