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.

A nanocomposite is typically defined as a mixture between a host material (e.g., polymer matrix) and nanofillers with at least one dimension of less than 100 nm.
Carbon-based Sustainable Organic Electronics (SOE) limit the use of critical elements and biodegrade at their end-of-life. This review offers insight on how structural and energy disorder in these materials influence device performance and includes evaluations of various transport models and their limitations.
Recent advancements in paper-based sensing platforms offer cost-effective clinical diagnostics with microfluidic channels and colorimetric or electrochemical detection zones.
SWCNTs show promise in FETs, solar cells, and photodetectors due to their ultrafast charge transport mobility.

How is shipping temperature determined? And how is it related to the product storage temperature?
1 answer-
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

Hello I wonder if these carboxylated CNTs are ready to use or need cleaning and activation steps. Also, what is the difference between this product and the other carboxylated CNTs available in your website?
1 answer-
652490 is carboxylic acid functionalized single-walled carbon nanotubes which are ready to use. Another carboxylated CNTs (P/N# 755125) are carboxylic acid functionalized multi-walled carbon nanotubes. Generally speaking, single-walled carbon nanotubes can provide a higher electrical conductivity than multi-walled carbon nanotubes.
