چکیده
Essential change of the splitting between reflections (200) and (i10) with temperature in the Blue Phase I (BPI) transmission spectrum in an electric field has been observed. The electrostriction coefficient ruin in BPI increases anomalously, while approaching the BPIBPII phase transition temperature. These results show that the phase transition is connected with lattice instability with increasing temperature. In crystalline liquids BPI and BPII iii the local orientational ordering of molecules forms

Electrostriction of BPI and BPII for blue phase systems with negative dielectric anisotropy
2014 The deformation of liquid crystalline blue phases BPI and BPII under the influence of a weak electric field is studied for systems with negative dielectric anisotropy. For the initially cubic structures of these materials, the interplanar spacings in the field direction were found to increase or to decrease in the field, depending on the orientation of the unit cell. In this paper, Kossel ...
متن کاملAffective instability, childhood trauma and major affective disorders.
BACKGROUND Affective instability (AI), childhood trauma, and mental illness are linked, but evidence in affective disorders is limited, despite both AI and childhood trauma being associated with poorer outcomes. Aims were to compare AI levels in bipolar disorder I (BPI) and II (BPII), and major depressive disorder recurrent (MDDR), and to examine the association of AI and childhood trauma withi...
متن کاملAnomalies of the temperature dependence of electrostriction in blue phases
We investigated the field-induced Shift of the blue phase diffraction bands. The temperature dependence of the electrostriction tensor components is determined for the first time. In the blue phase BPI at constant field strength E fl [001], a change of the temperture leads to a change of both the unit cell volume and its shape. The deformation of the unit cell displays a pretransitional behavio...
متن کاملElectrostriction of the cholesteric blue phases BPI and BPII in mixtures with positive dielectric anisotropy
The electrostriction of the cubic blue phases was investigated in the well known mixture CB15/E9. The results for BPI prove that a decrease of the lattice constant in the field direction with increasing field strength can occur in a system with positive dielectric anisotropy. In agreement with recent theoretical considerations, all components of the electrostriction tensor for this mixture exhi...
