This new technology makes it possible to obtain innovative composites and materials.

An international research team formed by staff from the Universitat Jaume I, the Centre for the Development of Functional Materials (CDMF) of the Federal University of Sao Carlos, the Department of Electrical Engineering (DEI) of the University of Sao Paulo and the National Nanotechnology Laboratory (LNNano) in Campinas in Brazil, have developed an electron beam irradiation system to obtain and modify materials in a scalable way.

The electron irradiation was applied to carbon to obtain different structures, including graphite, diamond, fullerene and graphene. Furthermore, the researchers were able to deposit iron, which acts as a catalyst to obtain multilayers of fullerene, as well as creating magnetite nanoparticles inside carbon nanotubes.

This new technology has been explained in the article «A scalable electron beam irradiation platform applied for allotropic carbon transformation» recently published in the journal Carbon:
