Ab initio studies of hydrogen adatoms on bilayer graphene

Mapasha, Refilwe Edwin; Ukpong, Aniekan M.; Chetty, Nithaya (American Physical Society, 2012-05)

We present a comparative density functional study of the adsorption of hydrogen on bilayer graphene. Six different exchange-correlation functionals are employed to explore the possible configurations of hydrogen ad- sorption ...

Phase evolution of vanadium oxides obtained through temperature programmed calcinations of ammonium vanadate in hydrogen atmosphere and their humidity sensing properties

Akande, A.A.; Linganiso, E.C.; Dhonge, B.P.; Rammutla, K.E.; Machatine, Augusto Gonçalo Jose; Prinsloo, Linda Charlotta; Kunert, Herbert W.; Mwakikunga, B.W. (Elsevier, 2015-02)

The possibility of obtaining vanadium dioxide (VO2) [wherein the vanadium ionic state is 4þ] from a precursor of ammonium metavanadate (NH4VO3) bearing the ion V5þ is investigated. The reduction is carried out by calcining ...
