Absolute molecular electronic spectroscopy at UV and soft X-Ray energies by hihg-energy electron impact
… spectroscopy has been used to determine absolute photoabsorption oscillator strengths (cross sections) for electronic excitation of CC14, CH3OH, NH3, CH3NH2, (CH3)2NH, and (CH3)3N at energy resolutions in the range 0.048-1.0 eV fwhm. These data have been obtained in the valence, and inner shells …

Photocatalytic Degradation of Perfluorooctanoic Acid in Water by Free and Immobilised ZnO, g-C3N4 and Their Composite under UV and Visible Light Irradiation
… could be an alternative to In₂O₃, as a benchmark photocatalyst for PFOA degradation, under ultraviolet (UV) irradiation. More interestingly, suspended ZnO nanoparticles showed promising for PFOA degradation under visible light irradiation (unlike In₂O₃ nanoparticles). The probable production of …
