In Fig. 3(c) of f-MWCNTs, the peak at 284.82 eV referred to the graphitic structure of carbon nanotubes (sp2 C=C) [31].
The presence of PANi can be clearly seen as non-uniform globular structures attached on the f-MWCNTs.
The core-shell structure was formed, where f-MWCNTs serve as the core, as shown by the coupled dashed arrows while PANi form the tubular shell that looks like jelly structure, as shown by solid coupled arrows [38, 39].

Moreover, titannium dioxide (TiO2) nanoparticles’ physicochemical such as chemistry, size, shape, surface structure and crystal structure that are important parameters for toxicity [16-18].
The crystal structures of pure TiO2 and TiO2/GSs composite samples used in this study are shown (Fig. 1).
The XRD patterns showed that the anatase structure of TiO2 was nearly unchanged in TiO2/GSs composite samples, which was comparable to that of pure TiO2.

X-ray diffraction (XRD) analysis was done for crystal structure determination of the SiC nanowires.
XRD measurements were carried out using Cu Kα radiation (λ = 0.154 nm) to determine the crystal structure of the SiC nanowires.
Fig. 1b displays an x-ray diffraction pattern of the SiC nanowires revealing the crystal structure as zinc blende.

CNTs adsorption model and simulation method
Kazemi model [7] is one of the most typical structures of dual porosity media in coal structure, which has been widely accepted.
CNTs surface is chosen to represent coal structure for adsorption investigation aim, because the surface structure of CNTs is similar to the lamellar structure of graphite.
The final structure of CNTs adsorption model is formed when a 10nm vacuum layer for free diffusion is added on the mixed system.
The bigger the binding energy is, the more stable the adsorption structure will be.

ES does not have a fatty acid-triglyceride structure.
The peak at 1.14 minutes in Figure 7 (a) is due to the natural essence structure.
The 1633 cm-1 peak shows the presence of the C=O structure from the ester.

More complex, hollow structures can be produced by hydroforming double blanks [2].
Applications range from thin heat exchangers to strong automotive structures, like rails or axle guides (Fig. 1).
The hollow structures can be used to gain additional stiffness or apply a stronger reinforcement, such as CFRP (Fig. 2).
Figure 2: Process chain for the production of CFRP reinforcemed structures Reinforced steel blanks like those shown in Fig. 2 could reduce the weight of automotive safety-relevant structures.
The hydroforming of hollow structures can be employed to reinforce pure metal parts, and the use of additional inlays from carbon fiber reinforced plastics could supply high-strength reinforcements and improved crash performance in automotive structures.

Swelling behaviors, micro pore structures, percentage of calcium atoms and tensile fracture stress of CIC hydrogel were investigated by weighting instrument, field transmission electron microscopy (FESEM), energy dispersive X-ray spectroscopy (EDX) and tensile strength testing machine, respectively.
Then, the Ca atom percentage, micro hole structure, swelling and mechanical properties were characterized by EDX, FESEM, weighing instrument and strength testing machine, respectively.
The surface water were removed, then these samples were put into freezer dryer at -60℃ for 10h. for FESEM observation, the gels were cut to little pieces for observing the pore structure and morphology of the sections.
CIC double network structure contributes to this trend.
