Almeida Assis, A.C.; Barbosa, M.F.; Valente Nabais, J.M.; Custódio, A.F.; Tropecelo, P.This paper describes the use of a diamond cell Fourier transform infrared (FTIR) spectroscopy methodology for the analysis of black toners commercialised in Portugal. A total of one hundred and thirty-eight samples from eighteen manufacturers were analysed in transmittance mode through a diamond cell. This methodology was considered to be non-destructive as it allows the forensic analysis of the questioned docu...

Valente Nabais, J.M.; Teixeira, Jorge Ginja; Almeida, I.The aim of the work now reported is the development of low cost electrodes in the monolithic shape without the need for a pos-production step with potential to be used in supercapacitors. The tested materials were activated carbon fibres prepared and activated carbons made from coffee endocarp. The main functional groups identified were quinone, lactone, Si–H, phenol, hydroxyl, carbonyl and ether for activated ...
