Analytical TLC was performed on SiO 2 plates (Alugram ® Sil G/UV254) or Al 2 O 3 plates (Poligram ® Alox N/UV254) and visualized with UV light (254 nm) or I 2 vapor. Preparative chromatographies were ...
Abstract: As ferrite have simultaneously non-negligible permeability, permittivity and conductivity, the magnetic behaviour of ferrite cores is frequency dependent. This article presents a method to ...
