Liquid crystal smart window based on the synergistic effect of the focal conic state and ionic turbulence
Abstract:
Over the past decade, the application of liquid crystal (LC) in switchable smart windows (SW) has emerged as a research hotspot. However, LC alignment technologies and their associated fabrication processes have constrained the further practical application of SW. This study proposes an alignment-free SW based on a negative dielectric LC (NDLC) system doped with S811 and DTAB, which achieves the synergistic effect between ionic turbulence and the focal conic state. Characterized by a simple preparation process and convenient operation, this smart window holds promising application prospects in architecture-related fields.

Crystal Field Theory - Octahedral Complexes
To explain the observed behavior of transition metal complexes (such as colors), a model involving electrostatic interactions between the electrons from the ligands and the electrons in the unhybridized d orbitals of the central metal atom has been developed. This electrostatic model is crystal field theory (CFT). It helps to understand, interpret, and predict the colors, magnetic behavior, and some structures of coordination compounds of transition metals.
CFT focuses on...
