TL;DR: In this article, the phase transition temperature of Li 2 Ge 7 O 15 was confirmed to be D 14 2 h - P b c n and C 5 2 v -P b c 2 1 above and below T c, respectively.

TL;DR: In this paper, a pair of wedge disclinations with strength of +1 and -1 emerge from bubble domains when a suitable electric field is applied, and the density of disclinations can be controlled by adjusting the field.

TL;DR: The temperature dependence of phase mode relaxation frequencies in the SmC A * phase, SmC γ * phase and SmC * phase were measured by photon correlation technique in R-MHPOBC (C 8 H 17 −COO-COO -COO * CH(CH 3 )C 6 H 13 ).

TL;DR: In this article, the Raman and fluorescence spectra of LaNbO 4 were observed in the temperature range from 15°C to 650°C with excitation light of various wavelengths.

TL;DR: In this paper, the switching characteristics of a ferroelectric liquid crystal with negative dielectric anisotropy were studied and an anomalous behavior was found in the applied voltage dependence of the switching time, i.e., with increasing applied voltage in the low voltage region the switching times decreased monotonically, while in the high voltage region it attains a minimum and then increases.
