摘要:Disclosed herein are certain embodiments of a novel chemical synthesis route for lithium ion battery applications. Accordingly, various embodiments are focused on the synthesis of a new active material using NMC (Lithium Nickel Manganese Cobalt Oxide) as the precursor for a phosphate material having a layered crystal structure. Partial phosphate generation in the layer structured material stabilizes the material while maintaining the large capacity nature of the layer structured material.

摘要:The present invention relates to the preparation of nucleic acids, nucleosides, nucleotides, and analogues thereof useful as potent and stable RNA interference agents. The present invention provides improved yields and avoids the use of lead tetraacetate for decarboxylative acetylation which decreases the overall cost of production by removing the need for lead remediation and offers a significant reduction in the environmental costs in production.
