Th-Based Endohedral Metallofullerenes: Anomalous Metal Position and Significant Metal-Cage Covalent Interactions with the Involvement of Th 5f Orbitals
Endohedral metallofullerenes (EMFs)
containing actinides are rather intriguing due to potential 5f-orbital
participation in the metal–metal or metal–cage bonding.
In this work, density functional theory calculations first characterized
the structure of recently synthesized ThC74 as Th@D3h(14246)-C74. We
found that the thorium atom adopts an unusual off-axis position inside
cage due to small metal ion size and the requirement of large coordination
number, which phenomenon was further extended to other Th-based EMFs.
Significantly, besides the strong metal–cage electrostatic
attractions, topological and orbital analysis revealed that all the
investigated Th-based EMFs exhibit obvious covalent interactions between
metal and cage with substantial contribution from the Th 5f orbitals.
The encapsulation by fullerenes is thus proposed as a practical pathway
toward the f-orbital covalency for thorium. Interestingly, the anomalous
internal position of Th led to a novel three-dimensional metal trajectory
at elevated temperatures in the D3h-C74 cavity, as elucidated by the static computations
and molecular dynamic simulations

Author, publisher and bookseller : a tripartite synergy in Nigerian book industry
This work is about the roles of Author, Publisher and Bookseller in Book development in
Nigeria. The paper started by delving into the history of Book Publishing in Nigeria after
which it proceeded by defining who an author, a publisher, and a bookseller is and
expatiated on the indispensable roles of these key actors in Nigerian Book Industry and in
the emerging Information Society. Furthermore, the various constraints to book
development were identified while the paper advised on how the Book Industry can be
further promoted in Nigeria. However, the paper concluded and made recommendations
on how the Book sector can help in enhancing scholarship in the country

Bicentenaire / R. Th. Laennec
Le mercredi 27 novembre 2019, une journée sera dédiée à la célébration du bicentenaire de la parution du Traité De l'auscultation médiate par René Théophile Laennec. Ce texte de 1819 marque un tournant dans l'histoire de la médecine au même titre qu'en physique les Principia de Newton ou la relativité générale d'Einstein. L'ouvrage de Laennec ne fut pas le simple mode d'emploi d'un instrument alors nouveau, le stéthoscope. Ce fut le fruit d'années de travail et de la réflexion quasi-obsessi..
