Synthesis and characterization of new liquid crystalline monomers for non-linear optics. X-ray study of re-entrand nematic behaviour with smectic-like fluctuations of C type
(Taylor & Francis Ltd., 1997)
The syntheses and structural properties of four liquid crystalline monomers are presented. They are prepared by two different reaction pathways. Transition temperatures and phase characterization were done by DSC, ...
Thermal characterization of an ultrasonic measurement cell
(2005-12-01)
Temperature plays an important role in any sensor device, because it can affect sensor properties, limiting its accuracy and operation range. At constant temperature, ultrasonic density sensors can reach accuracies of 0.1%. ...
Colorimetry characterization of molecular reorientation transition in thin nematic cells
(American Institute of Physics, 2020)
The characterization of equilibria and their transition is fundamental in dynamic systems. Experimentally, the characterization of transitions is complex due to time scales separation, the effect of thermal fluctuations, ...
Least squares method for liquid crystal display characterization
(OSA - The Optical Society, 2017-02)
This paper presents a method for liquid crystal display characterization. It assumes a liquid crystal display can be considered as a polarization-changing device described by a Jones matrix plus a global phase. The Jones ...
Trans-resveratrol-loaded nonionic lamellar liquid-crystalline systems: Structural, rheological, mechanical, textural, and bioadhesive characterization and evaluation of in vivo anti-inflammatory activity
(2017-09-14)
Resveratrol (Res) is a common phytoalexin present in a few edible materials, such as grape skin, peanuts, and red wine. Evidence has shown the beneficial effects of Res on human health, which may be attributed to its ...
THREE NEW IONIC LIQUIDS OF U-SHAPE N,N -DIALKYLBENZIMIDAZOLIUM SALTS: PREPARATION AND CHARACTERIZATION
(Sociedad Chilena de Química, 2010)
Synthesis and characterization of a novel liquid crystalline side chain metallopolymer
(Hüthig & Wepf Verlag, 1998)
The synthesis of a novel kind of form-retaining liquid crystalline crosslinked metallopolymer is reported. Copper(II) is complexed by Schiff's base units as part of a mesogenic side chain polymer. This leads to remarkable ...
Determination of the Real Influence of the Addition of Four Thickening Agents in Creams Using Rheological Measurements
(2013-04-01)
This study aimed to characterize different emulsions obtained by the addition of four thickening agents, using rheological measurements, beyond analyzing the emulsions by polarized light microscopy looking for liquid ...
