Zhang and Chan presented XPS analyses of PtRu nanoparticles prepared in water-in-oil reverse microemulsion [173]. The Pt 4f7/2 and Pt 4f5/2 lines that appeared at 71.30 eV and 74.57 eV, respectively, were attributed to metallic Pt0.

WebBACKGROUND: Secondary structures are elements of great importance in structural biology, biochemistry and bioinformatics. They are broadly composed of two repetitive structures namely α-helices and β-sheets, apart from turns, and the rest is associated to coil. These repetitive secondary structures have specific and conserved biophysical and geometric … WebControlling the equilibria between the cis and trans conformations of their backbone amides is the major hurdle to overcome for the construction of discrete folded structures, particularly for the development of all-cis PolyProline-type I (PPI) helices, as tools for modulating biological functions.
