We investigated the structural and magnetic properties of Ni42.5(Fe, Co, Ni, Cu)0.5Mn46Sn11 alloys fabricated by arc melting. Substitution of Ni by Fe, Co and Cu causes lattice expansions consistent with increasing atomic sizes. The zero-field cooled

Mesoporous 2D NiO–Nb2O5–Al2O3 nanorods (and, for the first time, template free ordered mesoporous alumina (OMA)) were prepared via glycol-thermal synthesis for the direct transformation of octane to octenes via CO2 assisted dehydrogenation (CO2-D

We report magnetic phase separation in pure La0.67Sr0.33FexMn1−xO3 (x = 0 and 0.5) ceramic samples. Rhombohedral crystal structures obtained with R3C space group show no significant changes in the lattice structures due to the close values of ionic

Cubic phases of bulk Mn-rich Ni 43 − x Ti x Mn 46 Sn 11 Heusler alloys (with x = 0, 0.5, 1 and 2) were fabricated by arc melting and their temperature dependent magnetic properties studied. The addition of Ti enhanced the saturation magnetization.

Nanoferrite of CoFe2 O 4 was synthesized using the glycol-thermal method at 200 ∘C for 6 h. The nanocomposites and nano-alloy were produced by the reduction of the ferrite using different amounts of activated charcoal at 900 ∘C for 3 h in high-pu
