Novel Semisolid Design Based on Bismuth Oxide (Bi2O3) nanoparticles for radiation protection
Objective(S): The dangerous effects of X-ray have been elucidated by scientific studies in occupational health hygiene. X-ray protective like an apron, thyroid shield and gloves have been made of lead (Pb) to protect against X-ray. However, such equipment makes a lot of safety and health problems such as toxicity, weight, inflexibility and troubles usage in a physician. To ove...
متن کاملGreen synthesis and characterization of bismuth oxide nanoparticle using mentha pulegium extract
In recent years, green synthesis of nanoparticles has attracted a great attention because of medicine and biological applications. In this work, bismuth oxide nanoparticles (Bi2O3 NP) was prepared via green synthesis using mentha pulegium aqueous extract after 24 h at 90°C. The product was characterized by ultraviolet-visible (UV-VIS) spectrophotometer, Fourier transform infrared (FTIR), X-ray ...

متن کاملAlfa- Bismuth(III)oxide catalyzed Biginelli reactions using experimentally designed optimized condition
α-Bi2O3 was synthesized via a hydrothermal method at 180 °C for 12 h in 1 (S1) and 2 (S2) M KOH aqueous solutions, using Bi(NO3)3•5H2O as raw material. The synthesized material was characterized by X-ray powder diffraction (XRPD) technique. The XRPD results indicated that by using 1M KOH aqueous solution, α-Bi2O3 was obtained with small fractions of β-Bi2O3, while 2M KOH solution resulted in pu...
متن کاملInvestigation of the Mass Attenuation Coefficient for Composites Containing Nano and Micro-Particles of Copper Oxide against Diagnostic X-ray
Radiation protection and the selection of suitable materials to reduce radiation effects is one of the important branches of medical science and radiation. In this paper, the mass attenuation coefficients, half value layer thicknesses and thicknesses of 0/5 mm lead of polyvinyl chloride (PVC) composites containing Nano and micro-particles of copper oxide are calculated using experimental method...
