Comeback of Incandescent Bulbs Thanks to Nanotechnology?

A group of researchers at the MIT has revealed a nanotechnological method allowing for a substantial increase in the energy efficiency of incadescent bulbs. The researchers coated filaments with several nano-sized layers. The resulting coating reflects the heat emitted by the filament but lets light pass, significantly lowering the total energy demand of the bulb. The results were published in the journal “Nature Nanotechnology”. Read more

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
