Resumo

O projeto, voltado para a Nanotecnologia Molecular, tem como estratégia a química supramolecular, explorando as interações cooperativas e os efeitos de organização na geração de nanossistemas automontados funcionais. Em seu escopo está a elaboração de interfaces moleculares capazes de promover a separação de cargas, transporte de íons e a transferência vetorial de elétrons ou de energia. Os sistemas em desenvolvimento também contemplam a associação de moléculas com nanopartículas, proporcionando nanomateriais heterohíbridos funcionais. Novos sensores amperométricos estão sendo projetados com nanomateriais automontados sobre a superfície de eletrodos, assim como dispositivos mais eficientes para fotoconversão de energia. No global estão envolvidas 6 linhas de pesquisas envolvendo: i) novos sistemas supramoleculares e hetero-híbridos, ii) novos dispositivos eletroquímicos e fotoeletroquímicos de alto desempenho, iii) sensoriamento plasmônico e SERS iv) magneto-eletroquímica e nanohidrometalurgia, v) captura de íons metálicos e remediação ambiental e vi) catálise e nanobiocatálise magnética. Além das novas arquiteturas moleculares geradas, os estudos ampliarão o conhecimento e as aplicações da espectroscopia eletrônica e vibracional, eletroquímica, espectroeletroquímica, fotoquímica/fotofísica, SPR, fotoeletroquímica, e microscopias AFM/STM, Raman confocal e Hiperespectral. Patentes e transferência de tecnologia também estão na meta do projeto, visando as áreas de petróleo, energia solar, biotecnologia e mineração. (AU)
