Behaviour of Fe-oxides relevant to contaminant uptake in the environment

TL;DR: The behavior of Fe-oxides was investigated during precipitation and co-precipitation, phase transformation and dissolution, while their ability to adsorb and incorporate trace components was examined as discussed by the authors.

X-ray diffraction analysis of a severely plastically deformed aluminum alloy

TL;DR: In this article, the lattice microstrains of the nanocrystalline Al solid solution determined from the X-ray diffraction analyses are isotropic along different crystallographic directions and high, exhibiting the same order of magnitude as the ratio of the tensile strength to the elastic modulus of the Al crystal.

Effect of La3+ substitution on the structural and magnetocrystalline anisotropy of nanocrystalline cobalt ferrite (CoFe2−xLaxO4)

TL;DR: In this paper, the saturation magnetization, coercivity and magnetocrystalline anisotropy constants increase with the increase of crystallite size and saturation magnetisation has been analyzed by the Law of Approach (LA) technique.
