Structural characterization, thermal properties, and density functional theory studies of PMMA‐maghemite hybrid material [PDF]

, 2016
Maghemite (γ‐Fe2O3)‐poly(methyl methacrylate) (PMMA) nanocomposites were prepared by grafting 3‐(trimethoxy‐silyl) propyl methacrylate on the surface of maghemite nanoparticles, this process being followed by methyl methacrylate radical polymerization ...

Phase and surface area studies of maghemite nanoparticles dispersed in silica gel [PDF]

, 2014
First, the superparamagnetic maghemite nanoparticles were synthesised using Massart's procedure. Then, the nanocomposites of the synthesised maghemite nanoparticles and silica were produced by dispersing the as-synthesised maghemite nanoparticles into ...

Kinetics of Thermal Transformation of Synthetic Al-Maghemites into Al-Hematites

Revista Brasileira de Ciência do Solo
Maghemite (γ-Fe2O3) and hematite (α-Fe2O3) are important iron oxides in Brazilian soils derived from basalt. Maghemite can transform into hematite when exposed to high temperatures. However, isomorphic substitution (e.g., Al3+) may largely influence this
