“…In a neutron shielding application, Florez et al (2018), Castley et al (2019), and Lv et al (2018) reported the use of REOs in different radiation shielding materials for improving shielding parameters with specific challenges. − Sm 2 O 3 is a very good neutron absorber and gamma actuator, and its potential use in Portland cement concrete depends on the optimization of Sm 2 O 3 and the cement, which is critical for achieving the desired structural, mechanical, and shielding characteristics . In another study, Castley et al (2019) reported comparative performance of boron carbide, gadolinium oxide, samarium oxide, and graphene plates where the optimized performance of neutron absorption requires even distribution of the particle in a highly viscous and elastic matrix, which is very challenging because of high surface energy . Therefore, it can be concluded that several challenges exist in the application of REOs in different shielding material systems to achieve the designed shielding parameters.…”

To date, rare earth oxides (REOs) have proven to be key components in generating sustainable energy solutions, ensuring environmental safety and economic progress due to their diverse attributes. REOs' exceptional optical, thermodynamic, and chemical properties have made them indispensable in a variety of sophisticated technologies, including electric vehicle magnets, portable energy devices, fuel cell catalysts, radiation shielding, dosimetry, and many others. Therefore, the successful incorporation of rare earth elements (REEs) into host materials in controlled concentrations offers competitive advantages to fabricate portable energy devices, radiation sensors, and radiation shielding glasses, as well as to improve the performance of existing photovoltaic cells, which is of great interest to both researchers and industry. As the global demand for REEs grows rapidly, it is critical to comprehend the underlying physics as well as the wider consequences of REEs on sustainable energy and nuclear technologies, both in the near and long term. However, despite their relevance, a focused review on the applications, prospects, and challenges of REOs in photovoltaics, nuclear, and energy devices is still unavailable. To this effort, this review succinctly reports recent experimental studies on eight REOs (R 2 O 3 , R = Yb, Er, Sm, Eu, Y, Gd, Dy, and Ce) and their specific applications and industrial aspects. While several subdomains are reported, the applications of REOs in next-generation solar cells and photovoltaic devices for promoting zero-emission clean energy and rechargeable batteries for electric vehicles (EVs) are the most pioneering ones. Furthermore, REOs' chemical stability and compositional versatility allow them to be used in a variety of high-efficiency energy converters, including solid oxide fuel cells (SOFCs). From the perspective of thermodynamic and structural stability, the gamma and neutron absorptivity of REO-doped (such as Dy 3+ , Eu 3+ , Sm 3+ , Nd 3+ , etc.) glasses shows improved shielding performance in radiation domains. Aside from the applications, the prospects of REOs presented in this article are likely to encourage current and future scholars to pursue a wide range of important studies in the fields of energy and nuclear systems. This review also reports the key challenges (i.e., material degradation, phase transformation, magnetic entropy shift, etc.) associated with REOs in a standalone section. These challenges demand the immediate attention of scientists and engineers for efficient, costeffective, and environmentally sustainable solutions. At the end, future advancement pathways for REO applications are also suggested.

Aiming to develop new magnetic materials for neutron shielding applications, B- and Gd-containing magnetic nanoparticles were synthesized. Following bottom-up synthetic approach, core-shell Fe 3 O 4/Gd 2 O 3 nanocomposite particles were synthesized at the first stage. In the next stage, magnetic core-shell particles were modified with amino groups followed by grafting onto their surface of the boronic acid derivative. Such a multifunctional material, containing both boron (B) and gadolinium (Gd) atoms is a promising candidate for developing films and membranes, strongly interacting with neutrons. Due to the presence of boronic acids and bound to the indicator (Alizarin Red S), the material can induce color changes while immersed in sugar-containing solutions. Such a feature enables a possibility to estimate the number of boron atoms left after interaction with neutrons, thus allowing to check composite neutron-capture recourse.

In this work, gamma-ray shielding features of crosslinked polystyrene-b-polyethyleneglycol block copolymers (PS-b-PEG) blended with nanostructured selenium dioxide (SeO2) and boron nitride (BN) particles were studied. This research details several radiation shielding factors i.e., mass attenuation coefficient (μm), linear attenuation coefficient (μL), radiation protection efficiency (RPE), half-value layer (HVL), tenth-value layer (TVL), and mean free path (MFP). The irradiation properties of our nanocomposites were investigated with rays from the 152Eu source (in the energy intervals from 121.780 keV to 1408.010 keV) in a high-purity germanium (HPGe) detector system, and analyzed with GammaVision software. Moreover, all radiation shielding factors were determined by theoretical calculus and compared with the experimental results. In addition, the morphological and thermal characterization of all nanocomposites was surveyed with various techniques i.e., nuclear magnetic resonance (NMR), Fourier-transform infrared spectroscopy (FTIR), thermogravimetric analysis (TGA), scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDX), and transmission electron microscopy (TEM). Acceptable compatibility was revealed and observed in all nanocomposites between the experimental and theoretical results. The PS-b-PEG copolymer and nanostructured SeO2 and BN particles exerted a significant effect in enhancing the resistance of the nanocomposites, and the samples with high additive rates exhibited better resistance than the other nanocomposites. From the achieved outcomes, it can be deduced that our polymer-based nanocomposites can be utilized as a good choice in the gamma-irradiation-shielding discipline.
