These methods have been used widely for spectroscopy in such areas as biology, food and polymer chemistry, and here for the first time we applied those for SiC analysis.
In order to uncover such underlying structure, data matrix X can be rotated into a new coordinate system in such a way that it is represented as a linear combination of principal component (PC) loadings V and PC scores T: X = T*V + E (1) where V is the abstract vector of so-called PC loadings, T is the abstract vector of PC scores, and E is residual.

Additionally, average particle size was less than 100 nm (Fig.2 A); PEDOT film showed loose belt network structure (Fig.2 C); the surface morphology of P(NPB-EDOT) film was different from PNPB and PEDOT, which exhibited a relatively smooth surface (Fig.2 B).

There have been efforts to improve the osseointegration capability of the titanium implants by enhancing osteoconduction on their surfaces using surface morphology and chemistry.
Various methods have been used to develop morphological structures of titanium implant surfaces to promote bone ingrowth and fixation between implants and bone: such as powder/fiber/wire mesh metallurgical sintering, surface blasting, vacuum plasma spray processing, micromachined method and chemical treatment [3-5].

The X-ray diffraction patterns of GDC heated at 1673 K were identified by those of cubic fluorite structure.

While after a given period of time, the conversion at a higher SO2 concentration is higher and the formed product layer has a thicker structure, which results in greater diffusional resistance to the reactant gas and a low conversion rate.
