Open the CIPO recordAbstract From the Canadian patent
A method for bulk separation of single-walled tubular fullerenes (100) based on chirality is provided wherein a first step is the formation of a template, (40) on a crystalline substrate (30). The template (40) has a plurality of openings, (32) which are oriented to energetically favor adsorption of a respective plurality, of single-walled fullerenes (100) having a tubular contour and a selected chirality. Next, the template (40) is exposed to a suspension (16) of singlewalled, tubular fullerenes (100) of random chiralities for adsorption of single-walled tubular fullerenes (100) of the selected chirality into the openings (32) of template (40). Then, the template (40) is removed from …

Why it's free to use
- Filed May 7, 2002. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended May 7, 2022.

- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
