WebThe optical properties of magnetite at room temperature were studied by infrared reflectivity measurements as a function of pressure up to 8 GPa. The optical conductivity spectrum consists of a Drude term, two sharp phonon modes, a far-infrared band at around 600 cm−1, and a pronounced mid-infrared absorption band. With increasing pressure both … Webpolaron: [noun] a conducting electron in an ionic crystal together with the induced polarization of the surrounding lattice.
WebIn addition, we exploited the formation of magnetic polaron states in Asp-CDs for H 2 O 2 photoproduction via WOR. Sole Asp-CDs were able to produce H 2 O 2 in pure water even without the presence of oxygen, and a further enhancement in H 2 O 2 reaction yield was achieved when 2-propanol was introduced into the reaction mixture, confirming its ...
