Applicazioni
- Vanadium(V) oxide is used in the preparation of vanadium alloys.[1]
- It is an oxidizing agent, commonly used as a catalyst in contact process (production of sulfuric acid) to oxidize sulfur dioxide to sulfur trioxide.[2]
- It is widely used as a host material for lithium-ion battery, sodium-ion battery, magnesium-ion battery and pseudocapacitors.[3][4]
- V2O5 is also used as the charge injection and extraction materials in organic electronic devices.[5]

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

How can I determine the shelf life / expiration / retest date of this product?
1 risposta-
If this product has an expiration or retest date, it will be shown on the Certificate of Analysis (COA, CofA). If there is no retest or expiration date listed on the product's COA, we do not have suitable stability data to determine a shelf life. For these products, the only date on the COA will be the release date; a retest, expiration, or use-by-date will not be displayed.
For all products, we recommend handling per defined conditions as printed in our product literature and website product descriptions. We recommend that products should be routinely inspected by customers to ensure they perform as expected.
For products without retest or expiration dates, our standard warranty of 1 year from the date of shipment is applicable.

Does the particles are in nano-scale? If so, what is the size in nanometers.
1 risposta-
The particle size of this material is not determined on a lot to lot basis. Historical data indicates 50% as +80 MESH or 177 um and 90% as +200 mesh or 74 um.

How is shipping temperature determined? And how is it related to the product storage temperature?
1 risposta-
Products may be shipped at a different temperature than the recommended long-term storage temperature. If the product quality is sensitive to short-term exposure to conditions other than the recommended long-term storage, it will be shipped on wet or dry-ice. If the product quality is NOT affected by short-term exposure to conditions other than the recommended long-term storage, it will be shipped at ambient temperature. As shipping routes are configured for minimum transit times, shipping at ambient temperature helps control shipping costs for our customers. For more information, please refer to the Storage and Transport Conditions document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/316/622/storage-transport-conditions-mk.pdf
