In the ferroelectric liquid crystal (FLC) SmC* phase, the helical structure of molecular alignment depends on temperature. It is important to control the helical structural parameters such as helical pitch and handedness for the application of FLC materials in the industry. In this study, we have investigated the temperature dependence of the helical structure of polymer-stabilized (PS) FLCs in terms of circular dichroism (CD) and optical rotatory power (ORP), and discuss the effect of introducing the polymer network into the FLC medium on the helical structure. It is found that the temperature dependence of helical pitch for PS-FLCs is linear.
Cellular array models of linear distributed parameter systems are proposed. One of the arrays is a discrete model of diffusion systems. The cells have one-bit variables E{ 1, -1 } and change their values according to a pseudo-random walker rule. Another cellular array is a one-dimensional discrete wave propagation system. The array makes unidirectional waves with spatially distributed three-level variables E{ 1,0, -1). Numerical experiment shows that the temporally or spatially averaged behavior of these cellular arrays coincides with the solutions of original diffusion and wave equations within 2.2% of error.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
