hello sir, i am 8th semester student of M.Tech Nanotech. I am working on ZnO nanoparticles, dopping of transition elements and Thin film. but sir due to lack of lab and faculty facilities problem to work further.

I am interested in applying these nanotools for low temperature ferromagnetism for DSM,solar cell....

i have ideas bt not getting platform to perform them. plz guide me sir....

Welcome - about us

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 editor@nanopaprika.eu
