Descripción general

Potassium iodide is widely used as an additive to fabricate perovskite solar cells and light-emitting diodes, to enhance their stability and performance. The excess I from KI fill in the Ivacancies and suppress potential pathways for ion migration. The K+ cations can bond with undercoordinated halides or passivate negatively charged trap states at the grain surface, which enhances the performance of the device. It can also be used as a catalyst in various reactions such as the synthesis of biodiesel and cyclic carbonates with five-membered rings.

Aplicación

  • Optimal concentration of potassium iodide to reduce the black staining of silver diamine fluoride: This research identifies the optimal concentration of potassium iodide to minimize staining from silver diamine fluoride in dental applications, relevant for material science focused on dental materials (Detsomboonrat et al., 2022).
  • Optimized assay for hydrogen peroxide determination in plant tissue using potassium iodide: This article discusses an optimized method for determining hydrogen peroxide levels in plant tissues using potassium iodide, useful for academic chemists studying plant physiology or oxidative stress (Junglee et al., 2014).
  • Potassium iodide as a low-cost cathode material for efficient potassium-ion storage: This research investigates the use of potassium iodide as a cost-effective cathode material for potassium-ion batteries, highlighting its potential in energy storage applications (Alanazi et al., 2020).

Preguntas

1–2 de 2 Preguntas  
  1. How is shipping temperature determined? And how is it related to the product storage temperature?

    1 respuesta
    1. 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

  2. How can I determine the shelf life / expiration / retest date of this product?

    1 respuesta
    1. 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.
      For more information, please refer to the Product Dating Information document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/449/386/product-dating-information-mk.pdf
