“…The electronic stopping power states the energy losses due to electronic interactions, while the nuclear stopping power expresses the energy losses based on the elastic collisions between the ion and the nuclei of atoms in the material. The stopping power depends on the magnitude of the radiation mass, charge, and kinetic energy as well as the effective atomic number and atomic density of the interacting medium [11]. In this context, the stopping power formula for heavy charged particles can be written as [12]…”

In this study, the resistance of the Rhenium-Boron (Re-B) based alloys against the transmission of charged particles such as electron, proton, alpha, carbon and oxygen was investigated using the stopping power as the characterizing quantity. For this, the collision, radiative/nuclear, total stopping powers and projected range of the charged particles in the Re40-B60, Re50-B50, Re58-B42 and Re60-B40 alloys were calculated using the ESTAR, and the the Stopping and Range of Ions in Materials (SRIM) Monte Carlo code. It was found that the stopping powers of the heavy charged particles tended to decrease with increasing the rhenium concentration. These results suggest that the boron element is more suitable for heavy charged particle shielding materials compared to rhenium element.

“…[5] For efficient attenuation of specific types of radiation, high absorption cross section for both primary and secondary flux is desirable. [9] One of such materials that is suitable for radiation shielding is Pb. This can be attributed to its high density of closely packed atoms, which causes incoming radiation to collide with the Pb atoms, making the element effective in attenuating X-rays and gamma rays.…”

Techniques for effectively harnessing lead (Pb) deposits for optimum utilization have attracted a lot of research interest. Results obtained from investigating the elemental composition, vibrational modes, and structural properties of a fired Pb composite deposit, which was purified using an electric kiln furnace and further annealed in palladium‐diffused hydrogen ambient, are reported in the present study. Both atomic force microscopy (AFM) and scanning electron microscopy (SEM) analysis on the deposit indicate that the Pb composite is composed of crystal‐like morphology. The vibrational modes obtained from the material are identical to the Raman spectrum reported for PbSO4 (anglesite). Also, data acquired from the energy dispersive X‐ray (EDX) analysis of the annealed Pb composite material confirmed the presence of zinc (Zn), carbon (C), silicon (Si), sulfur (S), and oxygen (O) in the material. At the same time, Pb appeared to be the primary constituent with reference to its weight percentage composition compared to other elements. Using the Fourier transform infrared (FTIR) spectroscopy technique, a slight shift in peak positions to higher wavenumbers was observed for most of the frequency bands in the FTIR spectrum compared to their position in the Raman spectrum. The cause of the shift in wavenumber is still subject to investigation but can be tentatively ascribed to be induced by factors such as a decrease in bond length because of modification in electronegativity of the atom or structural changes at the subatomic level. The photoluminescence (PL) spectra obtained from the sample showed overlapped weak emission bands which were observed in the ultraviolet (UV) and visible (VIS) region, while a small optical band gap of ∽ 0.1307 eV was extrapolated through the Tauc plot for the Pb composite material using a direct band gap transition approach. The findings from the present study may be vital for providing an improved understanding of the electronic and structural properties of the annealed Pb composite deposit, while promoting the development of a feasible approach for the recovery and recycling of Pb for future related applications.This article is protected by copyright.

“…The transmittance of transparent soda lime glass for near-infrared light at 4mm thickness is approximately 75–90% [ 6 ]. Near-infrared light (700–3000 nm) is the spectral region with the highest thermal energy [ 7 ], accounting for approximately52% of the total solar energy received on surfaces [ 8 ]. The high transmittance of glass for near-infrared light can easily cause temperature rise in internal spaces and produce light pollution [ 9 , 10 , 11 , 12 ].…”

Nano-WO3 particles are expected to find use in new shielding materials because of their significant absorption of near-infrared light in the 1400–1600 nm and 1900–2200 nm bands and high transmittance of visible light. In this study, WO3 was ground and dispersed using high-energy ball-milling to prepare a nano-WO3 dispersion using BYK331 as the dispersant and ethanol as the solvent. The prepared nano-WO3 dispersion was added to a photo-curing system and cured using UV irradiation to form films. The cured films were characterized using FT-IR, SEM, XRD, and TGA. The results showed that the nano-WO3 powder was evenly dispersed in the coating. The infrared blocking rate of the film continuously improved and the visible light transmission rate continuously decreased with increasing amounts of nano-WO3.For the film containing 6 wt%nano-WO3, the infrared blocking rate of the coating is 90%, the visible light transmittance is 70%, the hardness of the coating is 3B, and the adhesion is 3H. The thermal stability of the coating is also improved.
