Electrospun fibers are excellent candidates for use in tissue engineering as they form high porous and high surface area 3D porous mats that imitate cellular matrix structure [32].
The structures obtained via electrospinning are porous, and the free space can be used for embedding different matter that can potentially be released simply by applying stress or strain [45, 46].

The sphene structure can be described as composed of chains of corner-sharing SnO6 octahedra running parallel to the cell edges that are cross linked by silicate tetrahedral to form a SnOSiO4 framework that accommodates Ca2+ in irregular hepta-coordinated polyhedra [11].
The crystallochemistry of sphene structures indicates that the chromium cations in both structures are in octahedral sites, replacing Sn4+ ions.
Recent works concluded that in Cr-doped sphene structure most of tetravalent chromium cations form a solid solution with the sphene lattice by mostly substituting Sn 4+ cations in octahedral positions, while just a very small amount of Cr4+ might substitute Si4+ ions.

Encounters between dissimilar materials often involve at least one member that’s siliceous or has surface chemistry with siliceous properties; silicates, aluminates, borates, etc., are the principal components of the earth’s crust.
Interfaces involving such materials have become a dynamic area of chemistry in which surfaces have been modified in order to generate desired heterogeneous environments or to incorporate the bulk properties of different phases into a uniform composite structure.
The crystalline structures of photocatalysts were determined by X-Ray Diffraction (XRD) technique.
Results and Discussion The morphological structure of TiO2 particles was studied using SEM.

However, its molecular structure is rich in hydrophilic functional groups, including amino, hydroxyl, and aldehyde groups.
Moreover, it is worth noting that although ChNFs and chitosan have a similar chemical structure, ChNFs prepared in this work had a degree of acetylation of 73.0%.
Additionally, the low elongation at break of the cross-linked films prepared in this work was due to the cross-linking structure, which constrains the flexibility of chitosan chains.

The real surface area of Ni-Mo electrode is increased by nanocrystalline structure of coating, and Ni+Mo electrode had a rough surface because of molybdenum powders on the surface.
Ni+Mo/Ni-Mo electrode has both nanocrystalline structure and coarse surface, so its surface area is the largest, and 80 times larger than that of nickel foam electrode.

The results show that the low molecular weight polymer P1 exhibits smecitc A (SmA)-like structure at lower temperature and nematic phase at higher temperature.
To further elucidate the phase structure and transition of P1 more clearly, the optical textures shown by the polymer P1 were observed using PLM.
The chemical structure of the monomer was confirmed by 1H NMR and elemental analysis.
The structure characterization of the polymers was performed by 1H NMR and GPC, and the phase structures and transitions of the polymers were studied using DSC, PLM, and 1D WAXD.

Defect chemistry was studied by measuring structural and electrical properties of In-x-Cu2SnSe3 as a function of dopant concentration.
The observation of the (004) peak in Fig. 1 can identify the formation of the cubic structure [1].
Good grain growth with smooth surfaces and compact structure were observed for In-0.15-CTSe (Fig. 3(d)).
At this doping content, In is dissolved into the CTSe structure, therefore the enhanced mobility is not related to the second phases.
