Article
In this paper, silica aerogel was doped with two laser dyes, Crystal violet and Rhodamine B, dissolved in ethanol. All samples were prepared in two different ways, with different concentrations and compared with non-doped prepared aerogel. The first way is the modification after the samples are converted to gel. The second way, the modification pro...

Ultra-light pours hydrophilic silica were prepared by sol gel neutralization chemical method under the ambient temperature under the effect different molar ratio of oxalic acid (1, 2, and 3), to study its effect on the structure of silica aerogel based on water glass (Na 2 SiO 3. 5H 2 O) used as the precursors. The gel was washed with deionized dis...

The influence of dye laser Rhodamine 6G (R6G) on the molecular structure of silica aerogel prepared by normal drying method is reported. The study also tests the effect of dye concentration on morphological and physical properties. Fourier Transform Infrared Spectroscopy (FTIR) was used to examine this effect, in addition to Field Emission Scanning...

The absorption spectrum for three types of metal ions in different concentrations has been studying experimentally and theoretically. The examination model is by Gaius model in order to find the best fitting curve and the equation controlled with this behavior. The three metal ions are (Copper chloride Cu+2, Iron chloride Fe+3, and Cobalt chloride...

Skin cancer is the most common cancers in the last years, especially in the human body; the Melanoma is the most destructive type of skin lesions. Detect cancer is important at the initial stage, but only an expert dermatologist can detect which one is non-melanoma and melanoma. Computer-aided diagnosis (CADs) application to skin cancer is relative...

The varied thermal conductivity (insulation) of silica aerogel with heating for different pH has been investigated, it has been depended on ambient pressure drying method in the preparing silica aerogel samples, also six different pH of samples (1, 2, 3, 7, 8 and 9) were treated under five degree of heating with (50,100,150,200 and 250) ᴼC. This te...

A superhydrophobic silica has been utilized as adsorbed the Crude oil leaked during transport in the water of the Iraqi rivers, the capacity absorbing of the aerogel powder for crude oil has been determined. This technique is very important to get rid of environmental pollution caused by the leakage of crude oil in water, which in turn cause death...

Abstract:Hydrophobic silica aerogel have been prepared through two step acid-base catalysis recipe, via ambient pressure drying method. tetraethylorthosilicate was used as precursor, and trimethylchlorosilan as surface modifier. Three adopted molar concentrations of Chromium chloride are used; 0.019, 0.032, 0.051 [M]. In this paper, the molar ratio...

We have studied the synthesis environment of ambient pressure silica aerogels influence on their resulting morphological and optical properties. Transparent nanoporous silica aerogel was synthesized at ambient pressure using tetraethylorthosilicate precursor via a sol-gel process. Effect of drying control chemical additives and catalyst on physical...

Crystal violet is a dye laser that changes the color of its solutions depending on the type of solvent. In this research we have dissolved the crystal violet in methanol and got the solution with the color violet. Then we have varied the concentration ratio to 1×10-5 , 1.5×10-5 , 2×10-5 , 2.5×10-5 and 3×10-5 mol/liter. The absorption spectrum for s...

The effect of varying concentrations on the photophysical properties of the laser dye Rhodamine B (RB) in ethanol was studied both experimentally and theoretically. The fluorescence spectrum of these concentrations (1 × 10 -2, 1 × 10 -3, 1 × 10 -4 and 1 × 10 -5 mol/litre) was taken experimentally. Pure tuning of RB in ethanol was obtained. Red shif...
