Profile distribution, Z-scan technique, Optical limiting and thermal lens method studies on Cyanidin-3-O-glucoside chloride.

For the purpose of determining the characteristics of the Cyanidin-3-O-glucoside chloride (COGC) dye, both an FT-IR spectrometer and a UV-Visible spect rometer were employed through the process. At a wavelength of 473 nm, a diode-pumped solid-state (DPSS) laser with an adjustable wavelength was used to quantify the thermally induced optical nonlinearity of the dye in a solvent composed of dimethylformamide. For the purpose of measuring the optical response, the Z-scan technique was utilised.

Electrical, Thermal Lens and Optical Study of Fluorescein Film for Application As Organic Photovoltaic Devices.

This article is devoted to the study of various dielectric and optoelectrical parameters nonlinear optic behaviors, thermal lens and self-diffraction parameters of Fluorescein (FLs) doped polymethyl methacrylate (PMMA) films. The films were prepared with 60 mM. These studies are based on the calculated values of refractive, absorption coefficient, energy gap, extinction coefficient and nonlinear Refraction index .

Preparation and evaluation release of sodium alginate/chitosan polyelectrolyte microparticles containing rifampicin and theoretical study using DFT methods.

In this work, rifampicin-loaded sodium alginate/chitosan polyelectrolyte microparticles were prepared by the ionotropic gelation technique using CaCl as a cross-linking agent. The influence of different sodium alginate and chitosan concentrations on particle size, surface properties, and release behavior was studied. An infrared spectroscopy investigation verified the lack of any drug-polymer interaction.

Preparation and characterization of tin chloride-based polymeric composite for gamma shielding applications.

Thin films of Poly (ethylene-co-vinyl acetate)/tin chloride different weight (w/w) ratios were prepared using a spin-coating method. The diameter, height, grain size, and other morphological and structural features of the prepared thin films were studied using atomic force microscope (AFM) system. Moreover, the maximum surface roughness and average diameter of the prepared thin films were reported to weight ratio of 0.

The photovoltaic efficiency of the fabrication of copolymer P3HT:PCBM on different thickness nano-anatase titania as solar cell.

Organic solar cells based on (3-hexylthiophene):[6,6]-phenyl C61-butyric acid methylester (P3HT:PCBM) bulk heterojunction (BHJ) with an inverted structure have been fabricated using nano-anatase crystalline titanium dioxide (TiO2) as their electron transport layer, which was prepared on the indium tin oxide coated glass (ITO-glass), silicon wafer and glass substrates by sol-gel method at different spin speed by using spin-coating (1000, 2000 and 3,000 rpm) for nano-thin film 58, 75 and 90 nm respectively. The effect of thickness on the surface morphology and optical properties of TiO2 layer were investigated by atomic force microscopy (AFM), X-ray diffraction and UV-visible spectrophotometer. The optical band gap of the films has been found to be in the range 3.
