个人简介
Assistant Professor at the Department of Chemistry, University of Aveiro (UA), Portugal, and a researcher at CICECO - Aveiro Institute of Materials.
Ph.D. in Inorganic Chemistry (1996), at Imperial College, University of London, UK.
FRSC (Fellow of the Royal Society of Chemistry, UK) since 2014.
Coordinator at UA of the Erasmus Mundus Joint Master Degree in Sustainable Catalysis (SuCat) and Director of the Chemistry Master at UA.
Member of the scientific board of the UA Doctoral Programme in Nanosciences and Nanotechnology.
Published 123 papers and 3 book chapters, with ca. 4700 citations (h-index 36), and gave 17 invited talks at international conferences. Supervised 5 PhD Thesis and 5 Post-doctorates. Coordinated 2 FCT financed projects and was a member in other 11 projects. Member of COST Action CM1203: “Polyoxometalate Chemistry for Molecular Nanoscience” (PoCheMoN), and Management Committee representative for Portugal 2012-2016.
AREA OF SCIENTIFIC ACTIVITY
Inorganic Chemistry: Polyoxometalate based materials, in particular lanthanopolyoxometalate organic-inorganic hybrid materials and nanostructured materials. Coordination chemistry of second and third row transition metals and the lanthanides.
Raman spectroscopy: Surface-Enhanced Raman Scattering (SERS) for the study of metal nanoparticle assemblies with relevance in trace analysis and biodetection. Confocal Raman microscopy, combined with AFM and SNOM, for imaging of nanostructured materials (2017 WITec Silver Paper Award, https://raman.oxinst.com/paper-award).
DOMAIN OF SPECIALIZATION
Research was developed on the coordination chemistry of aromatic ambidentate ligands (such as picolinates and nicotinates) with second and third row transition metals and the lanthanides. The use of derivatised [60]fullerene ligands in the coordination to lanthanides was also explored. The preparation of new polyoxometalates was studied associated to its use as ligands in d and f metal complexes. The use of polyoxometalates as oxidation catalysts was investigated. Lanthanopolyoxometalates were used as building units to make luminescent nanosized materials, including film assemblies and polyoxometalate-anion-pillared layered double hydroxides.
Raman spectroscopy, SERS in particular, was used for the investigation of the adsorption modes and orientation of molecules on metal nanoparticle surfaces.
PRESENT RESEARCH INTERESTS
Polyoxometalates have been used as inorganic components in the construction of hybrid organic-inorganic functional materials, the preparation of new polyoxometalate-lanthanide-organic systems has been achieved. The incorporation of organic-inorganic hybrid compounds, based on lanthanopolyoxometalates, into nanosized SiO2 has been explored for the preparation of photoluminescent materials. The association of the polyoxometalate/SiO2 core/shell nanoparticles to specific antibodies, for the use as luminescent biomarkers, is under investigation. The preparation of new lanthanopolyoxometalate based nanocomposites is under investigation using substrates such as graphene, polymers or polysaccharides. Preparation of new SERS substrates of silver and gold nanoparticles incorporated in organic polymers and graphene. Confocal Raman microscopy, combined with AFM and SNOM, has been explored for imaging of nanostructured materials (WITec alpha300 RAS+ instrument).
