... The absorber can absorb the electromagnetic energy, thereby reducing the electromagnetic interference and the radar cross-section (RCS) of targets (such as fighters, tanks, antenna arrays, etc). Recently, numerous metamaterial absorbers (MAs) have been proposed and developed for microwave absorption and electromagnetic shielding [2][3][4][5][6][7][8][9]. Traditional metamaterial absorbers usually use opaque metallic-dielectric structures. ...

... LSPR occurs when light interacts with metallic nanostructures smaller than the incident wavelength. Nanostructures such as nanoparticles [16,27], nanodisks [28][29][30], nanohole arrays [31,32], and nanovoids [33,34] are used to generate LSPR. By adjusting the size and shape of these nanostructures, the resonance wavelength can be finely tuned due to the delay effect in the electronic vibrations within the metal. ...

... In practice, the electrochemical properties of the electrodes and electrolytes must be carefully balanced with secondary characteristics such as chemical stability and compatibility with other battery components. It is essential to ensure that the materials used in these components exhibit the desired electrochemical qualities while maintaining compatibility and stability throughout the battery's lifetime [2,10,11]. Battery research and development are focused on optimizing these components to enhance lithium-ion batteries' overall performance, safety, and longevity. Continuous advancements in electrode and electrolyte materials contribute to the improvement and widespread adoption of LIB technology [4,12]. ...

... Finally, Li 2 S was doped with a trace amount of Y 2 S 3 to enhance the discharge capacity while minimizing the required amount of dopant amount, because reducing the amount of additives can improve the total specific energy density 20) . Y 3+ tends to segregate at the grain boundaries and therefore may exist on the surface of Li 2 S and appears to have catalyst effects. ...

... In recent years, in order to adapt to various application scenarios, some new materials have been used in the design of absorbers, such as polydimethylsiloxane (PDMS) [10], Fe-B ultrafine particles [11], indium tin oxide (ITO) [12][13][14][15][16][17][18][19], and graphene [20][21][22][23][24]. Among these materials, ITO films become the most widely employed materials due to their high conductivity and high transmittance within the visible spectrum. ...

... Muto et al. reported the feasible controlled incorporation of two-dimensional hexagonal boron nitride (h-BN) sheets with alumina (Al 2 O 3 ) particles, forming Al 2 O 3 -h-BN core-shell composite granules [1]. The findings from this study would be beneficial for developing microstructurally controlled composite granules with the potential for scalable fabrication via powder metallurgy-inspired methods. ...

... Nowadays, layered double hydroxides (LDHs) are of great research interest due to their unique 2D structure along the lateral dimension, high ionic conductivity, exceptional electronic configuration, and relatively large surface area [21][22][23]. Generally, LDHs have octahedral coordination by hydroxyl groups, forming a positively charged brucite-like host layer, interlayer anions, and water molecules. ...
