Post-translational modification of proteins by N -phosphorylation of the basic amino acid residues plays important roles in biological processes. The high-energy P-N bond might have contributed to the evolution of prebiotic chemistry. N -phosphoryl amino acids (PAAs) can serve as interesting small molecular models for the study of P-N bonds in prebiotic chemical evolution...
The dispersion state and catalytic properties of anatase-supported vanadia species are studied by means of X-ray diffraction (XRD), laser Raman spectroscopy (LRS), H2 temperature-programmed reduction (TPR) and the selective oxidation of o-xylene to phthalic anhydride. The almost identical values of the experimental dispersion capacity of V2O5 on anatase and the surface vacant sites available on the...
