We present a combined experimental, theoretical, and numerical study of photon transport microscopic dynamics in rigid drying turbid thin films. Our setup is based multispeckle diffusing wave spectroscopy adapted for frequency sweep the illuminating source. apply our approach to simultaneously monitor changes optical properties films rutile TiO2 powder dispersed ethanol during full process. Accordingly, we introduce an extension diffusion model spectral speckle intensity correlations account...
In this study, we synthesized magnetite nanoparticles through a modified coprecipitation route and subsequently coated them directly with Curcuma longa extract. The resulting were then dispersed in distilled water to create nanofluid. particle size distribution ranged between 9 18 nm according Transmission Electron Microscopy Dynamic Light Scattering. nanofluid’s thermal parameters obtained by photothermal techniques, obtaining their diffusivity, effusivity, conductivity, heat capacity per...
In this work, we report experiments and a theoretical scheme of photon transport in the frequency domain rigid turbid media. We have employed spectral multi-speckle intensity correlations to estimate optical properties as mean free path absorption length systems. propose based on diffusion model using an effective path-length distribution backscattering configuration take explicitly into account particles scattering anisotropy parameter g. By studying Teflon slabs polymer matrices doped with...
In CdS/CdTe solar cells, the dependence on frequency of applied voltage is essential to improve theoretical results. Our model based conservation energy and charge considering a ternary layer existence plasmons in interface. this work, capacitance as function induced field heterojunction observed; furthermore, plasmon was formed interface surface semiconductor. The results provided with were compared experimental data, better adjustment obtained.

HfO2 thin films are proposed as high-k gate dielectric, especially for the fabrication of ultra-large-scale integration systems. The effect adding deionized water during synthesis on its structural and dielectric properties is reported. study nanostructured deposited crystalline silicon wafers made by applying ultrasonic spray pyrolysis (USP) technique. For hafnium oxide films, acetylacetonate was dissolved in dimethylformamide a source material. Varying substrate temperature from 400 up to...
