Several samples of TiO2 (anatase)-supported Mn oxide have been prepared by a wet impregnation method, named as XMn- TiO2 (with X = 0.5, 1.0, 1.5 and 2.0, the theoretical monolayer fractions). All samples were characterised by conventional techniques.

Síntesis hidrotermal de monocristales LnMn2O5 (Ln= Y, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho y Er)
Ten single crystals of the series LnMn2O5 (Ln= Y, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho and Er) were synthesized by hydrothermal synthesis in a single step and without subsequent thermal treatments from aqueous solutions of metals salts at 240 ºC.

By using the nitrate decomposition method in the presence of KNO3, we have been able to enlarge the compositional range of the cobaltlayered compounds Ln1-xSr1+xCoO4 (Ln: La, Nd, Gd) to 0≤x≤0.40 in the case of lanthanum, to 0≤x≤0.30 for neodymium, and to
