First-Principles Electronic-Structure Study of Graphene Decorated with 4d-Transition Atoms
Crystals, 2020 Adsorption configurations, electronic structures and net spins of graphene adsorbing 4d transition atoms are calculated by first-principles calculations to explore the magnetic modification of decorating metal atoms on graphene. Y, Zr and Nb atoms can be

Iron in intracellular infection: to provide or to deprive?
Frontiers in Cellular and Infection Microbiology, 2013 Due to their chemical versatility, transition metals were incorporated as cofactors for several basic metabolic pathways in living organisms. This same characteristic makes them potentially harmful, since they can be engaged in deleterious reactions like

Epitaxial growth of higher transition-temperature VO2 films on AlN/Si
APL Materials, 2016 We report the epitaxial growth and the mechanism of a higher temperature insulator-to-metal-transition (IMT) of vanadium dioxide (VO2) thin films synthesized on aluminum nitride (AlN)/Si (111) substrates by a pulsed-laser-deposition method; the IMT ...

Transition metal transport [PDF]
FEBS Letters, 2007 Transition metal transporters are of central importance in the plant metal homeostasis network which maintains internal metal concentrations within physiological limits. An overview is given of the functions of known transition metal transporters in the context of the unique chemical properties of their substrates.
