The structure of NdSD was characterized by elemental analysis and infrared spectrum.
Structure characterization and performance testing Elemental analysis (EA) : The fully dried NdSD samples were placed in the elemental analyzer to determine the content of C, H, N and S elements.

The physical and chemical modification of the pore structure of concrete had occurred in the presence of the pozzolans due to its micro-filling and pozzolanic effects [22].
The reason could be due to effect of filling the pores with micro fines and the pozzolanic activity of SSP, which leads to the formation of additional hydration products (C-S-H) gel and results in a pore refinement and a porosity reduction leading to a denser pore structure [21, 22, 25, 64 66].

The structures and performance of the product were characterized by IR, TG, POM and SEM.
The effect of the amount of liquid crystal on the properties of structure and swelling were conducted.
The internal structure was relatively compact with forming the most folds on the outer surface, which could improve the free space on the surface and inside, and the liquid crystal gel formed 2~8 μm channel structure by introducing different crosslinking dosage.
When the amount of crosslinking degree increased, the internal structure of the liquid crystal gel became close and gel could form the channel structure of 2~8 μm.

The crystal structure and morphology of the as-synthesized samples were characterized by XRD and SEM.
Clearly, pure BSCCO is thin flaky-stepped structure in addition to a small amount of irregular particles, as shown in Fig.7(a).

The best Optimized device structure, FTO/CuCSN/CH3NH3PbI3/ZnO/Pt, had a power conversion efficiency of 42.69%, according to simulation data.
Effect of the ZnO (ETM) layer thickness change on solar cells performance The thickness of ZnO as the Electron Transport Material (ETM) ranges from (0.01μm to 0.09μm) we studied changing the thickness of the electron transport material and found that 0.01 μm is the lowest thickness in solar cell structure matches to best efficiency that can be obtained from Zinc oxide as the (ETM) is 42.01%.

The aromatic structures of AICFB intermingle with cadmium metal ions via π-π interactions [21].

It is seen that undoped ZnO films contain uneven less uniform grains and ropes or ganglia-like structures.

The structure of Amberlite XAD-7 HP resin used in the SPE where R groups are polyfunctional aliphatic residues.[14] Ethyl acetate was used to remove less polar non-anthocyanin phenolics such as chlorogenic, neo-chlorogenic, quercetin, and myricetin from the SPE column.[17, 18] Acidified ethanol with the same concentration of acid used in the initial water extraction is then employed to recover the anthocyanins remaining on the SPE column.[14–16] The addition of HCl during the SPE elution of anthocyanins is required to prevent their degradation and to maintain the extracted anthocyanins in a stable form as the flavylium cation.

The simulated welding process included the creation of the heat affected zone and the development of residual stresses in the structure.
The armor plates were modeled using material properties of MIL-DTL-46100, Class I high hard steel [7], and AISI 8630 triple alloy steel which has a similar chemistry and for which strength vs. temperature data is readily available, (DIN 1.6545).
A realistic convection coefficient was assined to the structure’s surfaces to draw heat away from the welds.
