Production of graphene in solution by unzipping of carbon nanotubes

Cunha, E. M.; Oliveira, Elisabete; Paiva, M. C.; Costa, Florinda; Fernandes, António J.

Chemical modification of the outer graphene layer of carbon nanotubes is an approach increasingly used, mainly to overcome the problem of interfacial bonding with different materials. The effect of functionalization of CNT under different conditions, using the 1,3-dipolar cycloaddition reaction [1], was studied by Scanning Tunneling Microscopy (STM). STM demonstrated the potential for unzipping of the outer gra...


Antibodies against pseudorabies virus in feral swine in southeast Brazil

Cunha,E.M.S.; Nassar,A.F.C.; Lara,M.C.C.S.H.; Bersano,J.G.; Villalobos,E.M.C.; Oliveira,J.C.F.

Serum samples collected from 358 wild boars (Sus scrofa) in breeding farms in São Paulo, southeast Brazil, from 1998 to 2001, were tested for antibodies against pseudorabies virus (PRV) by means of serum neutralization (SN) and enzyme-linked immunobsorbent assay (ELISA). Seropositive animals were detected in three of seven herds analyzed. Overall seroprevalence as assessed by SN was 30.7%, ranging from 25.2% to...
