Electronic and magnetic properties of electron-dopedV2O5andNaV2O5Bhandari1, Lambrecht2 2015Phys. Rev. B13120View full textAdd to dashboardCite

“…The doping of V 2 O 5 is expected to play a significant role in various of its existing and potential applications. These include catalysis, 4,5 Li-ion batteries, 6,7 , electrochromic devices, 8 and electro-optical switching devices. 9 The catalytic properties in oxidation reactions are in part related to the vanadyl oxygens which are singly bonded to V. Removing this oxygen also dopes the lowest conduction band.…”

Chemical segregation and precipitation at anti-phase boundaries in thermoelectric Heusler-Fe2VAl

“…Due to the high affinity of vanadium to carbon, it can form carbides at temperatures of 800-1000 °C during the melt spinning process. It can also react with nitrogen at temperatures above 800 °C [25]. The tendency for segregation can be related to the relatively high APB energy of Fe2VAl is 0.27 ± 0.04 J/m² for a ( 2) ⟨111⟩(011) APB [26], compared to e.g.…”

Punching above its weight: life cycle energy accounting and environmental assessment of vanadium microalloying in reinforcement bar steel

“…In a typical co-production process, vanadiumcontaining pig iron is processed in an electric arc furnace for the concomitant production of steel and vanadium-bearing slag. Subsequent processing converts extracted vanadium into ferrovanadium or nitrides, which are used as precursors for the preparation of different grades of HSLA steels (Bauer, 2012;Weber et al, 2018).…”
