The present study focuses on the ionic behaviour in nanoparticles (NPs) dispersed nematic liquid crystal. Dielectric spectroscopy has been used to investigate of ions suspension NPs and crystal (LC). Ionic concentration, diffusion coefficient, activation energy mobility have calculated from dielectric data. It is found that ion concentration increases initially then it decreases with increasing suspension. initial increase attributed insertion more due impurities TiO2 various other reasons....
In recent years, there has been an unprecedented increase in the demand for fermented dairy products due to medical recommendations and lifestyle preferences. Cultured buttermilk, as ancient beverage, is appropriate product choice this context. This study presents a novel cultured buttermilk formulated by fortification with high protein microalgae Spirulina platensis, thus making it valuable attractive because of its antioxidant properties. The fermentation process, nutraceutical properties,...
In recent years, dispersion of nanomaterials in liquid crystal media has attracted a great deal attention for their applications various fields and basic understanding. this regard, nanocomposites ferroelectric crystals hold promise technological advancement displays, sensors, development hybrid materials optical others. With the emphasis on properties crystals, paper presents summarizing overview with critical comments progress made last one decade understanding influence nanoparticles...
Inorganic semiconducting ZnOS nano material were doped in the pure Ferroelectric Liquid Crystal and electro-optic as well dielectric properties have been scrutinized to understand nature of ferroelectric liquid crystal composite system (FLCNMCS). The changes characteristics FLC geometry alters its physical parameters. parameters FLCNMCS also depend upon concentration material. In present paper, change like permittivity, relaxation strength, activation energy, spontaneous polarization,...
The field of label-free biophysical technologies used to quantitatively characterize macromolecular interactions with each other and small molecules has grown enormously in the last 10 years. most widely analytical for characterizing biomolecular are surface plasmon resonance (SPR), isothermal titration calorimetry (ITC), biolayer interferometry (BLI), ultracentrifugation (AUC). Measuring interaction parameters accurately is challenging, as it requires specialized expertise, training,...
The experimental results of this work point out the role guest dye molecules in molecular ordering nematic liquid crystals. We have discussed changes energies interactions between rod-like and anthraquinone by considering presence steric dipole–dipole dye-doped system. concentration plays an important determination such systems. Below a certain (known as critical concentration), where interaction can be neglected, addition introduces some disorder into system form domain formation. Above...
Abstract The effect is reported of surface anchoring on various electro-optical parameters a pure ferroelectric liquid crystal (FLC) and five mixtures with different concentrations dye. Anthraquinone D5 dye was used as guest entity, whereas Felix 17-000 host in this investigation. presence molecules the FLC dramatically affects properties compared those system. Electro-optical such spontaneous polarization rotational viscosity not only change addition but they are also strongly dependent...
AbstractWe study how the dye dispersion influences properties of ferroelectric liquid crystal (FLC). The polarisation measurement shows decreasing linear behaviour with increasing concentration dye, indicating orientation in a direction opposite to FLC molecules. Accordingly, response time increases dye. Dielectric data clearly show existence two relaxation phenomena and dye–dispersed systems. strength Goldstone mode, which is observed around 200 Hz, has decreased frequency this mode shifts...

Abstract We have investigated the properties of liquid crystals (LCs) doped with ZnO (8% Cu doped) nanoparticles. The electro-optic LCs changed varying concentration dielectric anisotropy obtained from values permittivity at 5 kHz in nematic and smectic phases was found to increase increasing nanoparticles LCs. It has been established that effect on depends physical LCs; nanoparticle disturbs orientation ordering LC molecules. also influences switching behavior, splay elastic constant,...
Abstract The present article reports dielectric relaxation study of an unusual shaped liquid crystal dimer (H shape) in the temperature range 40–85°C. this is important due to presence azo central linkage, which photosensitive. indicates coupling between electric field and molecule H dimer.

Our intention in the present work is to find out role of dye molecular orientation weakly polar nematic liquid crystal D6AOB. The doping a introduces disturbance arrangement molecules. However, this found be sensitive concentration dispersed crystal. It that dyed less ordered than pure crystals. This behavior has been explained on basis intermolecular interaction, i.e., dipole–dipole interaction.
