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.

GaAs (100) GaAs 600 nm AlAs 20 nm GaAs 10 nm Al mask ∆FS Πy Πy Πx Πx AlAs 20 nm (a) InAs QDs (b) |0〉 |XX〉 EbXX |X〉 The spot size of 5 m excites in this case the emission of nearly one thousand QDs.
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.

Velasco-Santos et al.7 studied the surface modification of CNTs with 3mercaptopropyltrimethoxysilane (3-MPT), and showed that the silanization process did not change the crystalline structure of CNTs.
Ma et al.11 used the silane 3-glycidoxypropyltrimethoxysilane (GMO) for surface modifications of CNTs, and they found FTIR evidences for GLYMO epoxy groups.

Hamadache et al. [6] have reported that the thermal conductivity of mortars decreases with age and with the amount of cement replaced par pozzolan; this is due to the reduction in density and the increase in air content.
Laoufi et al. [7] have reported that natural pozzolans have been widely used, as substitutes for Portland cement in many applications, for their advantageous properties which include cost reduction, high compressive strength, especially in the long run, energy efficiency in buildings, decreased permeability and increased chemical resistance.
- The (Ca(OH)2) was completely decomposed by different acids following the chemical reactions reported by Benosman et al. [24,25] and also the calcite was consumed by acid attacks.

Pioneering research on the TLD to reduce structural response under wind or earthquake forces was conducted by Fujino et al. [5], among others.
Banerji et al. [6] revealed the need for greater mass ratio of the TLD to be more efficient for larger structural damping.
Tait et al. [7] studied the performance of unidirectional and bidirectional TLD for random vibrations while Tait & Deng [8] compared the performance of TLD with different tank geometries.

Coutinho et al. in [7] indicated that MLP is the most effective method for estimating missing RH values compared with multiple linear regression (MLR) and regional average (RA) in Brazil.
