Application

  • Vanadium(V) oxide is used in the preparation of vanadium alloys.
  • It is an oxidizing agent, commonly used as a catalyst in contact process (production of sulfuric acid) to oxidize sulfur dioxide to sulfur trioxide.
  • It is widely used as a host material for lithium-ion battery, sodium-ion battery, magnesium-ion battery and pseudocapacitors.
  • V2O5 is also used as the charge injection and extraction materials in organic electronic devices.

Metasurfaces control light propagation at the nanoscale for applications in both free-space and surface-confined geometries. However, dynamically changing the properties of metasurfaces can be a major challenge. Here we demonstrate a reconfigurable hyperbolic metasurface comprised of a heterostructure of isotopically enriched
