Experimental realization of constant current device using hydrogen bond ferroelectric liquid crystals.

Electrical, thermal, and spectral characterizations of ferroelectric liquid crystal obtained from the precursors namely camphoric acid and heptyloxy benzoic acid abbreviated as CA + 7BAO. This mesogen exhibits two phases smectic C* and smectic G* in its exothermic run. DSC thermograms reveals the phase transition temperatures and enthalpy values of those phases.

Dielectric relaxations in a liquid crystal along with thermistor application.

A thermotropic hydrogen bond liquid crystal ClBAO + 6BAO is synthesized by mixing in equimolar ratios of chlorobenzoic acid and hexyloxybenzoic acid. FTIR studies conform the formation of hydrogen bond between the precursors. This mesogen exhibits nematic phase with long thermal range.

Effect of a wear-resistant resin coat on the color stability of a resin-modified glass ionomer restorative material.

Aim: The purpose of this in vitro study was to evaluate the effect of the Equia Forte Coat on the color stability of Equia Forte Fil.

Materials And Methods: Sixty discs of Equia Forte Fil were randomly divided into two groups. One group of 30 samples was treated with Equia Forte Coat according to the manufacturer's directions.

Evaluation of Versatile CdS Nanomaterials Based Liquid Crystals Switchable Device.

Novel synthesis and properties of versatile CdS nanostructures (e.g., Nano-brush, nano-cube, nanosphere) dispersed liquid crystals application in chemical friendly medium exploring this article.

A study of gender-wise risk association between fatty liver and metabolic syndrome components (Asia-Pacific criteria) in a South Indian urban cohort.

Background: Metabolic syndrome (MS) is associated with fatty liver (FL) disease. Gender differences in this association are not known.

Aim: The aim of the present study was to determine gender-wise association between FL and MS components (using Asia-Pacific guidelines 2007) in an urban south Indian cohort with normal liver function tests (LFT).

Experimental and theoretical investigation of p-n alkoxy benzoic acid based liquid crystals - a DFT approach.

In the present study structural effects of alkoxy chain lengths and mesogen properties of hydrogen bonded (nOBASA) complexes (n=5, 6, 7) have been studied by density functional theory (DFT) calculations and Fourier Transform Infrared (FT-IR) spectrum. The B3LYP/6-311G(d,p) level of theory has been adopted for all the computations. The experimental FT-IR (400-4000cm(-1)) spectrum was recorded on the solid phase of the molecule.

Effect of Vibrio cholerae on chemokine gene expression in HT29 cells and its modulation by Lactobacillus GG.

Epithelial cells participate in the innate immune response to pathogenic bacteria by elaborating chemokines. This study examined the effect of Vibrio cholerae and Lactobacillus rhamnosus GG on inflammatory chemokine gene expression in the HT29 human intestinal epithelial cell line. HT29 cells were exposed to V.

Color changes of restorative materials exposed in vitro to cola beverage.

Purpose: The purpose of this in vitro study was to evaluate the color stability of restorative materials when exposed to a cola beverage.

Methods: Color changes in restorative materials caused by exposure to a cola beverage were studied using a split-plot experimental design. Three restorative materials (composite, resin-modified glass ionomer cement, and compomer) and 3 shades of each material under 2 surface conditions (polished and unpolished) were studied.
