These peaks are assigned to be Silk I structure (α-helix and random coil structure).
These new positions are assigned to be Silk II structure (β-sheet structure) [3-4].
This due partially to the conversion of the protein structure from Silk I structure to the less soluble Silk II structure [4].

Photovoltaics will play an increasingly important role in buildings of the future. [5] Green Chemistry leads us to green buildings: Green chemistry, also called sustainable chemistry, is a philosophy of chemical research and engineering that encourages the design of products and processes that minimize the use and generation of hazardous substances.
Warner developed 12 principles of green chemistry, which help to explain what the definition means in practice.
Structure depends on the interdependency of geometry and material.

Eventually, suitable steel chemistries were found which allow the inverted microstructure to be obtained.
It was found during mechanical testing that these structures typically fail by brittle fracture propagating along austenite grain boundaries.
The chemistry of the CPM REX 121 steel contributed to the complex globular V-W-Mo carbides being retained (Fig. 7).
With this goal, a suitable chemistry was sought which would allow the carbide network along austenite grain boundaries to be eliminated.
