This research includes the manufacture of a polymeric nanocomposite consisting of silicone rubber/polyurethane as a base, with the addition of the first filler of micro-lead with a ratio of 300 pphr and the second filler of nano-lead with different ratios (0, 0.2, 0.4, 0.6, 0.8 pphr). With the addition of hexane (liquid state) to the superposition using the casting technique at room temperature. The structural properties of the surfaces of the samples were measured using Fourier transformation spectroscopy (FT-IR) and the scanning electron microscope (SEM). In addition to studying the mechanical properties represented by each hardness, tensile, elongation, and elastic modulus. (FT-IR) showed the absence of a chemical reaction for all samples. While SEM measurements showed a homogeneous distribution of micro-lead and nano-lead in the presence of hexane equally, and there were no voids in the eyes of the prepared rubber equally. For the mechanical properties, we see that the hardness, tensile strength and modulus of elasticity continue to improve with the increase in the number of lead nanoparticles. And a decrease in elongation as a result of inverse proportion to the modulus of elasticity. From the results obtained, this composite can be used in gamma ray attenuation applications in shielding, especially in medical and industrial fields.

“…3 depicts the relationship between the MAC and the incident photon energies across various glass compositions. The dependence of MAC curves is contingent upon the specific photon energy regime, namely the photoelectric (PE; 0.005 MeV-0.1 MeV), Compton scattering (CS; 0.1 MeV-12 MeV), and pair production (PP; >12 MeV) regimes [5,18,[29][30][31][32][33][34]. A notable pattern observed in the behavior of MAC (mass attenuation coefficient) is a significant decrease in MAC values within the PE (photoelectric effect) region.…”

Sodium diborate glasses containing cadmium and lead oxides were fabricated by the melt annealing technique. Lead oxide was introduced at the expense of cadmium oxide to enhance its elastic and shielding properties. The density of the lead-free glass increased from 2.137 g/cm3 to 3.330 g/cm3 after replacing cadmium oxide with lead oxide. The density values were used to investigate the elastic properties of glass using the MakishimaMackenzie model. In addition, the Phy-X/PSD code was used to simulate the shielding properties of such glasses at different photon energies ranging from 0.005 to 15 MeV.

“…Consequently, several image processing techniques, including False Color composites (FCCs), Principal Component Analysis (PCA) and Minimum Noise Fraction (MNF), besides a previous geological map [42], were integrated to discriminate between the complicated lithologies of the study area. FCC is a normal RGB representation of 3 bands (any combination except the true-color composite) that depends mainly on the ability of each band to enhance lithological features, based on their spectral coverage [11,[43][44][45][46]. Combining representative bands can greatly improve the identification of features.…”

Impact of DEMs for Improvement Sentinel 2 Lithological Mapping Utilizing Support Vector Machine: A Case Study of Mineralized Fe-Ti-Rich Gabbroic Rocks from the South Eastern Desert of Egypt

Fused remote sensing datasets have greatly contributed to enhancing lithological targets and providing significant information for mineral exploration. For instance, multispectral datasets can discriminate rock units through their unique spectral signatures. Digital Elevation Models (DEMs) could be an effective tool boosting lithological discrimination based mainly on their topographic variations. Consequently, the current study applied the power of the support vector machine (SVM) algorithm and the integrated Phased Array L-type band Synthetic Aperture Radar (PALSAR) DEM and multispectral Sentinel 2 data to: 1—Create an updated lithological map of a poorly mapped arid terrain (Khashir-Ras El-Kharit district, Eastern Desert of Egypt), and 2—Compare and assess the distribution of ferrogabbros with the aim of improving the localization of these rock bodies and investigating their mineral content. Our results enhanced the lithological mapping and revealed a better generalization of mineralized ferrogabbros when the input was a fused DEM with Sentinel 2 compared to the salt and pepper effect observed when adopting the Sentinel 2 solely as the input data. Additionally, the current research strongly recommends detailed exploration programs for Fe-Ti oxide ores within the gabbroic rocks delineated through the resultant thematic map. The ferrogabbros were subjected to a comprehensive analysis involving whole rock geochemistry, XRD, EDX, and light-reflecting investigations, which revealed the existence of magnetite, titanomagnetite, and hematite. The titanomagnetite crystals display subhedral morphology and exhibit fine- to medium-grained surfaces with irregular shapes. X-ray diffraction (XRD) analysis revealed the presence of magnetite and hematite in the concentrated Fe-Ti oxides. Additionally, the whole rock geochemistry highlighted the origin of the ferrogabbros and their proposed tectonic setting as an alkaline to calc-alkaline magma type that developed in a continental arc setting.
