RISOptical properties of spinel MgAl2O4 oxide
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...
Synthesis and structure of spinel-type oxides in Mn, Co and Ni ternary system nanopowders at low temperature
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....

Preparation of single phase Zn2TiO4 spinel from a new ZnTi layered double hydroxide precursor
Influences of spinel type and polymeric surfactants on the size evolution of colloidal magnetic nanocrystals (MFe2O4, M = Fe, Mn)
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–NaBH4-mediated reduction of imines to secondary amines
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...
Microwave-Assisted Solution Combustion Synthesis of Spinel-Type Mixed Oxides for Esterification Reaction
), 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...
Evidence from detrital chrome spinel chemistry for Paleo-Tethyan intra-oceanic island-arc provenance recorded in Triassic sandstones of the Nakhlak Group, Central Iran
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...
