The crossover energy of 1.8 eV (marked by an arrow) is determined by the strain in the InAs dot, valence-band offset between AlAs and strained InAs, confinement energy of the holes, and possibly some diffusion of Al into the dot.

Polarization reconfiguration can be achieved by using a switching mechanism where the ON and OFF states of the switches can reconfigure antennas between linear polarization, left-hand circular polarization (LHCP), and right-hand circular polarization (RHCP) (Yassin et al., 2019).

Sadighi et al. (2010) [26] claimed that the crushing strength of a composite is improved when the cell wall thickness of the honeycomb core is increased by delaying plastic deformation.
Besides, Wang et al. (2019) [27] found out that less indentation in the supporting region with less deflection are detected when thicker wall is used.
Moreover, Surya et al. (2019) [29] realized that the thickest wall at 0.2 mm exhibits the highest stiffness compared to the thinner walls at 0.05 mm and 0. 1 mm made of nickel alloy.

In several studies, fabrication of MOF’s nanocomposites like Ag NPs onto UiO-66(Zr) has been done by the impregnation method wherein Mahugo et al. prepared Ag@MIL-100(Fe) nanocomposites by employing a different procedure [40-42].
Yaghi et.al discussed slow diffusion of Zn (NO3)2 reacted with benzyl -di- carboxylic acid (H2BDC) in presence of triethylamine (TEA) for a week time [45-53] that produced MOF-2, MOF-3, MOF-5.

The same phenomenon was observed in Carozzi et al. [9] where pre-cracked FRCM coupons were subjected to freeze/thaw cycles, resulting in a moderate deterioration (16%) if compared to non pre-cracked specimens subjected to the same conditioning.
In Donnini et al. [10], tensile tests were conducted on a PVA (polyvinyl alcohol)-coated AR glass FRCM composite exposed to different aggressive environments, namely saline, hygrothermal, and wet/dry cycles in the presence of chlorides.

In Fig. 3(a), the XRD pattern of Fe₃O₄ nanoparticles confirms the formation of magnetite, displaying characteristic diffraction peaks corresponding to the face-centered cubic spinel structure of Fe₃O₄, as reported by Szotek et al., with eight distinct peaks matching the (220), (311), (400), (422), (511), (440), (620), and (533) crystal planes, aligning well with the pure Fe₃O₄ standard from the JCPDS database [13].
For instance, Liu et al. (2015) [18] reported that the mean diameter of Fe₃O₄@SiO₂_NH₂ nanoparticles can reach approximately 210 nm, while Islam et al. (2024) [19] documented an average crystallite size of about 7.0 nm for Fe₃O₄@SiO₂_NH₂ nanoparticles, indicating a high degree of crystallinity.
