Al-alloyed MgB2 was prepared by solid state reaction of Mg (1-x)A1(x) alloy and crystalline B powder particles. The nominal composition of the samples was Mg1-xAlxB2, with x = 0, 0.1, 0.2, and 0.3. Microstructure and chemical composition have been investigated by scanning electron microscopy (SEM), electron probe microanalysis (EPMA), and...

The crystal structure, magnetic and magnetocaloric properties, and the critical behavior of representative compounds in the pseudo-ternary NdxGd3−xCoNi series have been investigated (x = 0.15, 0.5, 1.0, and 1.5). All these phases are isotypic with the parent compound Gd3CoNi, crystallizing with the monoclinic Dy3Ni2-type (mS20, C2/m, No. 12)....

Giulio Monteverde (1837–1917) was one of the major and most important sculptors of the early 1900s, both in Italy and at a worldwide level. Monteverde is mainly known for the artworks he realized in stone and metal, but he still remains almost unacknowledged for his plaster statues. Until today, neither the manufacture, nor the chemical...

A study on the formation and stability of new quaternary compounds with the general chemical formula Gd3 TAl3 Ge2 (T = Mn, Cu) has been undertaken by experimental investigations (SEM-EDX, DTA and XRD) and density functional theory (DFT) calculations. These compounds crystallize in the hexagonal Y3 NiAl3 Ge2-type structure (hP9, P62×, Z = 1) (an...
