Ostracoda Substitutional Name

Zenkovia, a new generic replacement name for preoccupied Scaphella Zenkova, 1977 (Ostracoda) non Swainson, 1832 (Gastropoda).

The generic name Scaphella was proposed by Zenkova (1977: 81; type species S. gibbosa Zenkova, by original designation) for a new fossil ostracod genus from the Middle Silurian (Wenlockian) of the eastern slope of Middle Urals (Russian Federation). However, this name is already preoccupied by a marine gastropod molluscan generic name Scaphella Swainson (1832: pl. 87), which is in active current...

Taking the idea seriously that non-referring names like ‘Superman’ and ‘Clark Kent’ are indeed names and that they do not refer (to anything whatsoever), it is argued that the usual characterization does not only give rise to theories which inflate ontolog...

Substitutional alloy of Ce and Al.

The formation of substitutional alloys has been restricted to elements with similar atomic radii and electronegativity. Using high-pressure at 298 K, we synthesized a face-centered cubic disordered alloy of highly dissimilar elements (large Ce and small Al atoms) by compressing the Ce(3)Al intermetallic compound >15 GPa or the Ce(3)Al metallic glass >25 GPa. Synchrotron X-ray diffraction, Ce L(...
