Nonlinear Optical Spectroscopy of Liquid Droplets : Chemical Composition within the Interface Final Report

The Third Order Nonlinear Optical behavior of Poly Ether Urethane

Poly (ether) urethane close/open cell (PEUCC/PEUOC) has been prepared by using in situ polymerization approach. The third-order optical nonlinearities of dissolved samples in DMF were characterized by Z-scan technique at the measurement wavelength of 532 nm. The synthesized samples were also examined by optical microscopy and UV-Vis absorption spectroscopy. The nonlinear refractive (NLR) indice...

Modeling the Surface Tension and the Interface of Ten Selected Liquid Mixtures: Correlation, Prediction, and the Influence of Using Partial Molar Volume

This work investigates the modeling of the surface tension and the interface of liquid mixtures. Nine binary liquid mixtures of (DMSO+alcohols), (2-Propanol+2,2,4-trimethylpentane), (Tetrahydrofuran+2-Propanol), (Tetrahydrofuran+2,2,4-trimethylpentane), and (ethano+glycerol) are considered. Additionally, one ternary liquid mixture of (Tetrahydrofuran+2-Propanol+2,2,4-trimethylpenta...

Rotational Diffusion of Monodisperse Liquid Crystal Droplets

many isotropic oils, this liquid crystal is not soluble in water. We therefore We have prepared monodisperse suspensions of nematic liquid use an ionic surfactant, sodium dodecyl sulfate (SDS), to stabilize the crystal droplets in water. The droplets are stabilized by polyvinyl droplets. This allows us to use standard fractionated crystallization methods alcohol, a polymer that induces planar a...

Electro-Coalescence of an Aqueous Droplet at an Oil–Water Interface with an Investigation of Secondary Droplets Formation

Nano-droplet formation in polymer dispersed liquid crystals

In this work we analyse the fabrication of Polymer Dispersed Liquid Crystals (PDLCs) using SU8-2002-2007 photoresist and 5CB and E7 Liquid Crystals. Also we report the nonlinear optical behaviour for these materials and for Polymer Dispersed Liquid Crystals with a Twisted Cell (T-PDLC). We found that depending of several parameters, the droplets size varies from nano to micro dimensions. We rep...
