Abstract- The optical properties such as the dielectric function, the reflectivity, the refractive index and the loss function

have been calculated for spinel MgAl ˻O ˽ oxide using density functional theory (DFT). The full potential...

techniques. The a average particle size was estimated to be about 65nm iin diameters with the cubic phase. The formation of spinel stru ucture of powders has been studied by Fourier trtransform infrared (FTIR) spectroscopy....

Two types of polymeric surfactants, PEG300 and PVP40000, were used for the preparation of magnetic

ferrite MFe2O4(M = Mn, Fe) colloidal nanocrystals using a solvothermal reaction method. The effect of spinel type effect on the size evolution...

Nano-sized NiLa2O4 spinel was produced by thermal decomposition of Ni–La compounds via a

sol-gel method. The well-crystallized spinel structure was formed after calcination at 750 °C. The

physicochemical properties of the spinel were...

), Fourier transform infra-red (FTIR), Brunauer–Emmett–Teller (BET) surface area measurement, scanning electron microscopy (SEM), and transmission electron microscopy (TEM). The spinel-type zinc aluminate was successfully synthesized, but CuO-modified alumina...

Detrital chrome spinel (Cr-spinel) is for the first time described from Nkhalak Group which is a distinctive Triassic (Late Olenekian-? Early Carnian) sedimentary succession in Central Iran. Previously published data from the Nakhlak Group suggest...

Structral,electronic and optical properties of spinel MgAl2O4 oxid...
