To mimic cancelous bone and to promote tissue repair mechanisms a highly macroporous structure with open cells is desired.
The open porous structure was retained and the materials showed good cytocompatibility.
Only the struts of the PU scaffold should be coated with slurry in order to remaine the open pore structure.
The structure was analysed by SEM (DSM 940, Zeiss, Oberkochen, Germany) and light microscopy (Wild, Wetzlar, Germany).
Microstructure changed to a more facetted surface morphology while the macropore structure was maintained.

Finally, the structures of the crystals extracted from the Gynura Segetum (Lour.)
Finally, the structures of the extracted crystals were analyzed by infrared spectroscopy.
Finally, the colorless crystals were further washed with acetone for several times and the crystal structure was analyzed by infrared spectroscopy.
However, as shown in Fig. 2, too long irradiation time could destroy the structures of the extracts from the Gynura Segetum (Lour.)
The structures of the extracted colorless crystals were analyzed by infrared spectrometry.

In this research, we prepare an aligned ZnO nanorods structured thin film by using a CBD method and they grow on glass and silicon substrate using pressurized air.
To obtain the detailed structure information, the grain size along c-axis was calculated according to the Scherrer formula [16].
The hexagonal structure was observed by FESEM and well aligned, compact and perpendicular ZnO nanorods grew on the surface of glass substrate.
It was investigated that for sample 16, the well-alligned ZnO nanorods show the formation of hexagonal wurtzite structure which describes the nanorods as a polycrystalline.

In order to ensure that the perfect pattern with minimum defect structure is obtained, the process parameters should be optimized and controlled.
This fabrication process considers the difference in parameters to ensure the patterns produced have perfect surface and minimum defect structure [3].
The response on fabricated IDEs was characterization on morphological structure and electrical properties using HPM and IV test.

As one of the important ferrites with spinel structure, magnesium ferrite (MgFe2O4) has been intensely studied in many areas including magnetic applications [14], catalyst [15], humidity sensor [16] and pigment [17].
The structure, morphology and magnetic properties of the resulting films have been investigated.
The appearance of (003) and (006) reflections confirms the layered structure of the LDH materials.
As can be seen from Figure. 6a, the layered structure of LDH has been destroyed during calcination process because no characteristic diffractions of LDH are present.

For both structures the rate is increased by 1.5-2 orders of magnitude while the lithium concentration is increased up to 0.5 value.
For the parameters calculation a large set of structures was generated with DFT-PBE calculations by VASP 5.2.
For all structures the set has information about all atom coordinates and forces acting on the atoms as well as the total energy.
At the beginning of MD simulations all Li atoms formed slab of native BCC structure lying above (001) Si surface.

This technique acquires the utilization of conductive ink to form a fine and thin resolution conductive structure on a flexible substrate.
Furthermore, a fine structure construction often demonstrated poor device performance due low mechanical durability.
It is believed that smooth structure, the uniform and small distribution of particle size, will enhance the conductivity and reduced the resistivity.
In order to characterize the mechanical endurance of printed Mi-Ag ink, a bending test was carried out for RFID tag structure design.

SEM analysis proves that the morphology of cement structure is well arranged and compacted leads to enhance the compressive strength by 20%.
Nano TiO2 has three crystal structures: anatatse, rutile, and brookite.
The hydrated product with TiO2 nanoparticles which gives hardness and compact structure inside the cement pastes structure is weak and not well compacted to clinker surface previous paste.

Very promising results were obtained for an Al-Hf-Sc-Zr alloy, which maintained mainly an unrecrystallised structure after extrusion and large degrees of cold rolling.
The grain structure in the profiles was characterised by optical microscopy on polished and anodised samples in the longitudinal section, while transmission electron microscopy using a Jeol 2010 TEM operated at 200 kV was used to characterise the crystal structure and the distribution of the dispersoids.
These clusters subsequently transformed to spherical Al3Scdispersoids displaying the L12-structure.
Even after 80% cold rolling this alloy displayed a completely fibrous structure after annealing at 600ºC (see Fig. 3b).
It is still, however, remarkably stable, and the structure is mostly fibrous even after annealing of the 80% cold rolled variant at 600˚C (Fig. 3a).

The porous structure can be observed between the flakes.
The further addition of the mesoporous carbon may result in the blockage of the porous structure in the α-Ni(OH)2, thereby leading to a decrease specific capacitance.
