purification of nanomaterials is a pretty popular problem there could be a group for this problem alone. in my experience in research and development I've found very few affective solutions. deionizing resin has many drawbacks as its a difficult material to handle and it often picks up the desired material as well as the unwanted contaminants. flushing by settling and decant (often assisted by centrifuge) will help provided the contaminants aren't within the particle. another method I've found which is rarely mentioned is filtering through an ultra filter with finer particle solutions as it leaves the particle in tact while removing salts. i feel like there's a lot of research to be done using electricity maybe ionic membranes.hope this helps
Welcome! Nanopaprika was cooked up by Hungarian chemistry PhD student in 2007. The main idea was to create something more personal than the other nano networks already on the Internet. Community is open to everyone from post-doctorial researchers and professors to students everywhere.
There is only one important assumption: you have to be interested in nano!
Nanopaprika is always looking for new partners, if you have any idea, contact me at firstname.lastname@example.org
