Raman analysis revealed that increase in deposition pressure from 2 to 5 Torr resulted in the transformation of the film structure from diamond-like-carbon to nanocrystalline diamond structure.
X-ray diffraction was used to study the composition of the crystalline phase composition in the film structure.
The origin of this PL emission could be from the disordered sp3 phases present in the film structure.
The PL emission produced by green light excitation is mainly produced by the non diamond phases in the film structure.

The oxidation state of sulfur on the air side surface of float glass heat-treated in N2/H2 and the bulk samples of the other two were determined by X-ray absorption near edge structure spectra (XANES).
X-ray absorption near edge spectroscopy (XANES) is highly sensitive to the oxidation state and coordination chemistry of the absorbing atom.
The sharper one at 2473.7eV corresponds to 1s to mixed S 3p and metal 3d states which depend upon the electronic structure of the compound [16].

To gain a better understanding of the aggregation-structure relationship of the 7 residues of the Yeast prion-like protein, the change in the conformational structure is studied by Transmission Electron Microscopy and will be further studied by 13C solid-state NMR.
It was further noted that two or more filaments were able to associate laterally to form fibrillar structures with a larger diameter.
The RP-HPLC purified SupN peptide obtained from the thrombin cleavage of the GST fused SupN was confirmed by ESIMS and formed a fibrillized amyloid structure.
The fibrillized structure was confirmed by Congo Red binding studies under a polarizing microscope(data not shown, yet green birefringence was observed) and Transmission Electron Microscopy. 13C and 15N chemical shifts in peptides and proteins are quite sensitive to the local secondary structure [11-13].
Thus, 13C chemical shifts can be used in characterizing the secondary structure of the SupN fragments.
