Radial direction elasticity of CNTs is important especially for carbon nanotube composites where the embedded tubes are subjected to large deformation in the transverse direction under the applied load on the composite structure [3].
Because of their hollow structure and high aspect ratio, they tend to undergo buckling when placed under compressive, torsional, or bending stress [7].
Electrical Properties Because of the symmetry and unique electronic structure of graphene, the structure of a nanotube strongly affects its electrical properties.
This reduces the mean free path and reduces the thermal conductivity of nanotube structures.
Parameters such as structure, size distribution, surface area, surface chemistry, surface charge, and agglomeration state as well as purity of the samples, have considerable impact on the reactivity of carbon nanotubes.

The MIL matrix structure contains two types of cages of 2.9 and 3.4 nanometer size, connected through smaller windows (ca. 1.4 nm) [15].
Our data confirms that the polyaniline is confined within MIL structure so the size of the conducting phase is limited to an order of several nanometers.
We found that this unique composite structure leads to a change of conductivity behavior in comparison to the bulk polyaniline.
The X-ray diffraction confirmed, that the MIL-101 structure is maintained after the aniline oxidative polymerization.

The morphology and structure of the hollow spheres with cubic mesopores are characterized by XRD, SEM, TEM, and N2 adsorption/desorption isotherms.
From the images of intact and crushed spheres (Fig. 1A-C), one can conclude that the spherical morphology and a hollow structure could be obtained after calcination.
The formation of the cubic mesopores and hollow structure is proposed based on an approach of O/W microemulsion.
Additionally, calcination in oxygen makes it easy to release the oil core through the channels, leading to hollow structure.
Hollow structure is obtained after calcination at high temperature, suggesting highly thermal stability of HSCMS.

Crystallite can be considered a number of cells with crystalline structure that are systematically linked and are creating coherently diffracting domain.
It is a part of matter with continuous regular structure.
Samples of compact recrystallized structure needed higher temperature for total decomposition of CaCO3 and similarly for a creation of CaO, compared to samples of porous structure, as is shown in Table 5.
The main influencing factors are the genesis and diagenesis of limestone, which directly affect the porosity and thus the rate of heat transfer through the structure.

ZnO structures more to agglomerate and form a crack layer.
This phenomena will effect to the orientation of ZnO grow and reduced the crytallinity of structures.
ZnO with hexagonal wurtzite structures was obtained in all samples.
According to that finding, when the number of nitrogen in ZnO structures increase, the numbers of free carrier also increase.
The impurities (dopand) in the nanostructures can affect the electrical and physical properties of the structures.

The porous structure which mimics bone scaffold helps in reducing the stiffness mismatch between bone tissue and implant.
Palm stearin binder consists of fatty acid which is used as a surface active agent, where their chemistry and rheological properties can be modified to meet the specific requirements of MIM during debinding stage [10] [11].
The addition of a space holder promotes the formation of functional pores in the titanium structure, which support mechanical interlocking with the surrounding bone tissues, due to the bone ingrowth into the implant structure.
The density of metal with an open-cellular structure is an important parameter for predicting permeability and mechanical properties.

There are four sets of structures which extend NE, EW, SN and NW in the mining district.
The most important structures in this area are the Wuzishan anticlinorium and the Jiasha synclinorium.
The ore possesses zonal and tubercular structure with the strawberry and colloidal texture of pyrite.
The oxide ore minerals are limonite, hematite, cerusite, pyrolusite, etc．The main structures of ore are banded structure and nodular structure, which commonly seeing Colloidal texture, Oolitic texture and strawberry-like texture in the pyrite.

PCMs are a class of materials of physical state or molecular structure change at a certain temperature range.
In the process of change in physical state or molecular structure, large heat absorbed or released or vice versa [3].
With the advent of PCM implemented in gypsum board, plaster, concrete or other wall covering material, thermal storage can be part of the building structure even for light weight buildings.
The TEM image of composite PCM According to the TEM image as shown in Fig. 4, it can be seen that there is a dramatic difference between the two from analysis of the interlayer structure.

The resulting compacts were fired at 1300˚C for 5 h in a steam atmosphere to develop the structure of the scaffold.
Structure of apatite fibre scaffold (S2000). toward larger pore size, that is, in the range of 100-500 µm.
The present good cell proliferation results may be due to the 3D structure of the S2000 apatite fibre scaffold.
The strength of the S2000 scaffold was, however, enhanced after calcification of the bone marrow cells, allowing them to form a bone-like structure.
The bone marrow cells cultured in the scaffold were calcified creating a bone-like structure.

Central fusion and distributed fusion are two mainly used structures in data fusion systems.
These two structures have different characteristics.
So, this structure requires high processing speed because there is a large amount of data transmission.
Another structure which is called distributed fusion structure is exactly the opposite.
Each sensor in the structure should make its own decision and sent decisions to the fusion center.
