The presence of alloying elements, sometimes in a very small amount, affects mechanical properties one of these elements is Boron. In Aluminum industries, Boron master alloy is widely used as a grain refiner In this research, the production process of Aluminum –Boron master alloy was studied at first then, it was concurrently added to 2024 Aluminum alloy. After rolling and homogenizing the resu...

Bisbenzimidazoles have a broad spectrum of potential applications: radioprotectors, drug delivery vectors, antiviral agents, etc. At the same time, they seem to be promising fluorescent probes for radiation measurements. Therefore, in present work, response X-ray irradiation Hoechst 33258, one most widely known representatives bisbenzimidazole family, was studied first time. Irradiation dye per...

Low dose detection of g radiation remains critical for radiology therapy and nuclear security. We report herein on a novel dual-band fluorescence sensor system based on a molecule, 4-(1H-phenanthro[9,10-d]imidazol-2-yl)-N,N-diphenylaniline (PI-DPA), which can be dissolved into halogenated solvents to enable expedient detection of g radiation. The limit of detection was projected down to 0.006 G...

In This research, gold nanoparticles were synthesized and functionalized by the antibody of aflatoxins. The quenching of the fluorescence of excitation emission matrices (EEM) of two type of aflatoxins (B1, G1), provoked by the gold nanoparticles, was studied by principal component analysis (PCA) and multivariate curve resolution with alternating least squares (MCR-ALS). These aflatoxins show q...

Thermal quenching is described as a decrease in luminescence efficiency with increasing measurement temperature. Luminescence intensity decreases heating rates the presence of thermal quenching. In such case, rate to be used measurements becomes important. Lithium fluoride (LiF) type dosimeters have been widely radiation dosimetry for many years. this study, effect was investigated LiF:Mg,Ti (T...

curcumin (cur) is the active curcuminoid with many physiological, biochemical, and pharmacological properties. solubility and stability of cur is the limiting factors for realizing its therapeutic potential. bovine β-casein is an abundant milk protein that is highly amphiphilic and self-assembles into stable micellar nanoparticles in aqueous solution. β-casein nanoparticle can solubilize cur mo...

We provide a theory of dynamo (alpha effect) and momentum transport in three-dimensional magnetohydrodynamics. For the first time, we show that the alpha effect is reduced by the shear even in the absence of magnetic field. The alpha effect is further suppressed by magnetic fields well below equipartition (with the large-scale flow) with different scalings depending on the relative strength of ...
