A new type magnetic solid acid catalyst (Fe 3 O 4 @ETMS-TETA-SO 3 H) was prepared and applied in the alcoholysis of dioscin from Dioscorea Zingiberensis C.H.Wrigh to obtain diosgenin for the first time. The solid acid was characterized by FTIR, TGA, TEM, SEM, EDS-mapping, XRD, VSM...
FTIR carbon free SiO 2 film, which showed a bulk-like refractive index, was prepared with a deposition rate of 0.16 nm/s. The external magnetic field and Ar inert gas strongly influence SiO x physical properties. Such effects may be due to the enhancement of the excited atomic oxygen and ...

This spectrum is identical to a previously reported ESR spectrum (C.S. Lai and L.H. Piette, Tet. Letters, 9, 775 (1979)) obtained during a Fenton reactions using 2-methyl-2-nitrosopropane, which had been assigned to the hydroxyl radical adduct. This note presents evidence that this four...
