Abstract null null A catalyst is a substance that changes the rate of a reaction. In the petroleum industry, the catalysts are commonly used for fluid catalytic cracking and hydrocracking carried out with catalyst, each of them applied in a specific stage. These catalysts are used to facilitate the molecular chains cracking, which will generate a mixture of hydrocarbons. However, the catalyst gradually loses its activity, either by changing its original molecular structure or by its contaminatio...

Since we are able to bring ionizing radiation in the form of a gas cloud to the respiratory system, we have wondered whether Xenon-133 inhalation could be exploited as a treatment option against Covid-19 respiratory virus infections, and urge colleagues in the scientific research community who have the capability to do so to explore the merits of using Xenon-133 in this way to determine whether its usefulness against the Covid-19 virus is indeed genuine.

Abstract null null This paper evaluates the γ-radiation shielding traits of some new types of borate glasses of composition (70–x)B2O3–10Bi2O3–10BaO–10CdO–xPbO (where 0 ≤ x ≤ 20 mol%) prepared using melt quenching method. As-quenched samples were characterized to determine the effects of various PbO contents on their γ-radiation shielding properties. XRD patterns of the samples verified their amorphous nature. The Phy-X and XCOM was used to compute the mass attenuation coefficients of the glasse...

Abstract null null The radiation-induced emulsion graft polymerization method is limited for applying concentrations higher than the monomer concentration that enables stable formation of monomer micelles. Furthermore, foaming may occur because of the presence of the surfactant, which is essential for the formation of micelles, resulting in likely splashing around a highly flammable monomer emulsion. In the present study, to overcome these issues, we investigate the effect of added alcohols on t...

Abstract null null Presently, scientists and scholars are faced with techniques of maintaining and elongating optimum performance of energy storage devices operating under radiations exposures. This review examine the effects of radiations such as ions, neutrons, laser, gamma etc. in electrodes of energy storage devices capacity loss, resistance increase, breakdown and poor performance as a result of radiation absorbed from surrounding environment. Radiations effect on electrodes of energy stora...

Abstract null null This paper reports an increase in the optical reflectivity of two kinds of copolymers used in contact lenses, with different proportions of silicon and fluorine derivatives, when irradiated with 4.1 MeV alpha particles from an 241Am source. The fiber-optic reflectance technique showed that the lens with a higher proportion of silicon and fluorine content and a lower proportion of methyl-methacrylate is more susceptible to alpha radiation. X-Ray photoelectron spectroscopy and R...

Abstract null null The structural, morphological and optical properties of selenium thin films are important for the application in electronic and optoelectronic devices. In the present work, the effect of annealing in vacuum at different temperatures (130 °C, 160 °C and 200 °C) and swift heavy ion irradiation (Ag9+ ions with energy of 120 MeV) at different fluences (5 × 1011, 1 × 1012, 5 × 1012 and 1 × 1013 ions/cm2) on various properties of thermally deposited Se thin films has been investigat...

Abstract null null It is known that ZnO is at the forefront in recent studies, so one of the most important applications in recent years is improving the properties of zinc oxide by grafting with cheap and environmentally friendly materials. In the present work, the effect of natural eumelanin (Mel) and gamma radiation on the morphological characteristics, structural, optical, and electrical properties of ZnO nanocomposite were routinely studied. The transmission electron microscope (TEM) images...

Abstract null null A method for determining the irradiation histories of plant-based food items was developed. The developed method was based on that used for determining the irradiation history of animal-based food items. The liquid chromatography–tandem mass spectrometry (LC-MS/MS) technique was used to analyze the total amount of (5S)- and (5R)-5,6-dihydrothymidine (sum of (5S)- and (5R)-DHdThd; total DHdThd), which are radiolytic products of thymidine (dThd). Red peppers were used as a model...

Abstract null null Reduced graphene oxide (rGO) is supposed to have better stability and adsorption properties than graphene oxide (GO). Here, GO was controllable reduced by γ-ray irradiation at low doses of 0–10 kGy. Both physicochemical characteristics and filtration performance of GO/rGO membranes were investigated. The XPS, FTIR and UV spectra data showed that both the types and contents of the oxygen-containing functional groups changed after irradiation, but were not linearly correlated wi...
