Diffusion Of Indigo Molecules Inside The Palygorskite Clay Channels
Catherine Dejoie, Pauline Martinetto, Eric Dooryhee +6
The search for durable dyes led several past civilizations to develop artificial pigments. Maya Blue (MB), manufactured in pre-Columbian Mesoamerica, is one of the best known examp…
Revisiting Maya Blue and Designing Hybrid Pigments by Archaeomimetism
Catherine Dejoie, Eric Dooryhee, Pauline Martinetto +9
Maya Blue is actually one of the best known examples of an organic-inorganic hybrid material. Yet despite 50 years of sustained interest, its microscopic structure and its relation…
Structural and magnetic properties of the (Bi2-xPrx)Ru2O7 pyrochlore solid solution (0 <= x <= 2)
Siwar Zouari, Rafik Ballou, Abdelwaheb Cheikh-Rouhou +1
We report a detailed study of structural and magnetic properties of the pyrochlore-type (Bi2-xPrx)Ru2O7 series. Eleven compositions with 0 <= x <= 2 were prepared by solid state re…
Synthesis and structure of new pyrochlore-type oxides Ln2ScNbO7 (Ln = Pr, Nd, Eu, Gd, Dy)
Siwar Zouari, Rafik Ballou, Abdelwaheb Cheikh-Rouhou +1
We report the synthesis and structural study of mixed oxides in the Ln2ScNbO7 series. New phases with Ln = Pr, Eu, Gd and Dy are obtained. All crystallize in the cubic pyrochlore s…
Electrochemical lithium intercalation in nanosized manganese oxides
Pierre Strobel, Céline Darie, François Thiéry +4
X-ray amorphous manganese oxides were prepared by reduction of sodium permanganate by lithium iodide in aqueous medium (MnOx-I) and by decomposition of manganese carbonate at moder…
Effect of mixed alkali-element substitution on structural and magnetic properties of praseodymium manganites Pr0.9(Na1-xKx)0.1MnO3
Siwar Zouari, Laurent Ranno, Abdelwaheb Cheikh-Rouhou +1
The effect of cationic size mismatch at the A site at constant manganese valence on the structural and magnetic properties of a perovskite-type rare-earth manganate was investigate…
