Disclosed here is a method of fabricating a covalently reinforced carbon nanotube (CNT) assembly. The method includes producing a CNT assembly by pulling entangled CNTs from a CNT array fabricated on a substrate, the CNT assembly including a plurality of CNTs that are aligned; and creating covalent bonding between the CNTs of the CNT assembly by applying a high energy ion irradiation to the CNT assembly.

The present invention relates to a process for ion irradiation of a particulate substrate containing the steps of embedding particulate substrate in a solid matrix having .sup.10B atoms, and exposing the matrix obtained in the previous step to a neutron flux to give irradiated particulate substrate. The process is extremely effective and amenable to large scale and is particularly suitable for producing irradiated nanodiamonds and irradiated SiC particles.

The present invention relates to a process for ion irradiation of a particulate substrate containing the steps of embedding particulate substrate in a solid matrix having 10B atoms, and exposing the matrix obtained in the previous step to a neutron flux to give irradiated particulate substrate. The process is extremely effective and amenable to large scale and is particularly suitable for producing irradiated nanodiamonds and irradiated SiC particles.
