The mixture of the resulted powders with a gel of collagen with native structure was lyophylisated for the preparation of nanocomposites in form of matrix (70% collagen and 30% bioactive ternary nanostructured powder).
Composition and structure of the resulted powders and their precursors were investigated.
The corresponding SAED pattern (figure 2b) is characteristic for a polycrystalline material with diffraction rings that can be indexed to the interplanar distances of an apatite-like structure.
Due to the specific structure of titania aerogel, intercalated nanostructures are formed.

With an olivine structure, LFP provides higher security [2]and stablity compared with other lamellar compounds[3], for instance, the LiCoO2[4] , which is characterized by high cost and toxicity.
The P-O covalent bond in olivine LFP is strong enough to prevent the battery from exploding even in case of a short circuit due to the stability of olivine structure[5].
These results can be attributed to that LiFePO4 itself has stable structures, the lithium source is not easily evaporated, which leads to unnecessary excess lithium.

The patterning of differently fabricated graphene layers into structures below 10nm is a precondition to achieve a band gap opening due to lateral confinement [1].
BSEs are responsible for the interproximity effect of narrow structures leading to merging and overexposure effects.
As the forward scattering angle in thin layers is independent of the thickness, the minimum structure size is only depending on the resist layer (40 nm).
The fabricated resist structures of three samples were transferred using ICP plasma etching technique and oxygen plasma chemistry for 30s and 5mTorr pressure at 200W plasma power.
Additionally a discrepancy can be seen as the so structured graphene exhibits higher line widths than the HSQ.

Hydroxyapatite (HAP, formula Ca10(PO4)6(OH)2) is a mineral with a complex crystal structure.
This indicates an unexpected differential incorporation of heavy metals in these two biomineralized structures.
