    摘要: Provided is a novel method for efficiently separating a metallic SWNT and a semiconducting SWNT from single-walled carbon nanotubes (SWNTs). The present invention is a method for separating a metallic SWNT and a semiconducting SWNT from SWNTs, said method comprising: dispersing the SWNTs in a solution containing a low-molecular-weight compound having an alkyl chain moiety for exhibiting solubility in a solvent and an aromatic-ring-containing moiety for interacting with the SWNTs; and separating the dispersion into a solution fraction and a solid fraction.

    摘要: A method for the recovery of riboflavin from a fermentation broth or other feed stock is disclosed. The method comprises a process for the production of large, pure riboflavin crystals from an alkaline, aqueous solution containing solubilized riboflavin. The method can further comprise the process for production of large, pure riboflavin crystals in combination with two solids/liquid separation steps, the latter of which can result in a final riboflavin product purity of at least about 96% by weight.
