The surface structure of microgel is rather accidented full of mesoporous.
Contrarily, there is no apparent viscosity after microgel formed due to its cross-linking structure.
A: POM results of the representative microgels in alcohol; B: SEM results for diameter analysis of the representative microgels; C: SEM results investigation of the surface structure of the representative microgels; “1”: Sample 1, “2”: Sample 2.
The representative surface structures of the two samples are all in typical irregular massive structures with numerous fissures and shown in Figure 1C.
The microgel is analogous to a kind of mesoporous material from the observation of surface structure.

Based on the XRD results, it is revealed that ZnO-TiO2 nanocomposite consists of hexagonal wurtzite structure of ZnO and mixed of anatase/ rutile phase of TiO2.
FESEM images showed ZnO in rod-like structure while TiO2 is formed in nanoparticle.
Analysis results of XRD, Raman and HRTEM revealed that the molar ratio of the components affects the crystalline structure of the synthesized oxide materials.
Analysis of porous structure parameters showed that an increase in the ZnO content leads to a decrease in the BET surface area.
The presents of hexagonal wurtzite structure of ZnO with anatase/rutile phase of TiO2 confirmed the sample are composite.

Metallic structures confined at the nanoscale acquire interesting properties such as strongly localizing E fields on their surfaces through Plasmonic Resonance under stimuli of light at certain wavelengths.
This nanostructures are called plasmonic structures [3–5].
This effect is exploited to amplify the optical signal obtained by the molecules of interest, located near plasmonic structures [3, 6].
The optical signal, is partially absorbed by the plasmonic Ag NPs structures binding the species of interest and is then detected by the bottom optical photodiode.

According to the thermodynamic previsions of defects structures, the external part of all the scales grown in oxygen exhibits band gap energy around 3.5 eV, with a marked p-type character on chromium and a possibly n-type behaviour on stainless steels.
It is of major importance to improve the knowledge on the point defect chemistry of this compound that grows during alloy service, so that transport properties through the oxide can be evaluated.

All of the MCC samples showed the similar pattern with the typical crystalline structure of cellulose I.
The crystalline structure of cellulose has been widely studied.
These peaks have a comparable patterns and supposed to represent the typical cellulose I structure.
High crystallinity indicates an ordered compact molecular structure which interpret the dense particles while lower crystallinity indicates a more disordered structure, resulting in a more amorphous powder.

However, the introduction of the concrete admixtures, changing holding conditions of the samples, the volume restriction can affect the strength of the due to exposure impacts both the kinetics of hydration processes and on the structure formation of cement paste.
Such conditions are called constraint expansion and can affect both the structure of the cement stone by changing the density and porosity, and strength characteristics.

Has an interconnected pore structure to allow 3D bone ingrowth; 4.
To do that it must have a suitable interconnected pore structure.
In order to be able to develop such a structure, it is necessary to be able to image and quantify the pore structure throughout the scaffold.
At present many highly irregular structures cannot be fully quantified.

The annealed Gd0.94-xAlxEu0.06VO4 phosphors crystallized in the tetragonal structure.
The crystal structure of the annealed Gd0.94-xAlxEu0.06VO4 powders was analyzed with an X-ray diffractometer (XRD; Rigaku RINT2000).
The patterns can be indexed as the tetragonal structure, irrespective of composition [10].
The doped Al3+ did not cause much change in the crystal structure of the phosphor powders.
