Perfil biográfico

Received her degree in Biological Engineer from the Universidade do Minho in 1993, and completed her Ph.D. in Materials Chemistry at Universidade de Aveiro in 1999, under supervision of Prof. João Rocha. This was followed by a post-doctoral work with Prof. Michael Anderson at Department of Chemistry, UMIST, Manchester- England (1999-2000), Prof. João Rocha at Universidade de Aveiro (2001-2003). In 2003 was starting working as solid state NMR technician, in 2006 started to work with single crystal X-ray diffraction. In 2009 was admitted as an auxiliary researcher at CICECO. Currently her researcher interests included both, design, synthesis and characterisation of multinuclear copper and iron complexes with anticancer properties as well novel organic-inorganic hybrid compounds with different transition metal for magnetic applications. Crystal structure determination by single crystal x-ray diffraction

Interesses científicos

My current research interests include both synthesis and characterisation of novel microporous silicate materials with metals in various coordination environments and crystal structure determination of new compounds by single crystal X-ray diffraction.

I have been focusing primarily in transition metal silicates, including titano-silicates (ETS type materials), niobium-silicates, vanado-silicates with V in different oxidation (V(III), V(IV) and V(V)  and coordination environments; octahedral and pyramidal coordination), and copper-silicates.

As part of the characterization of the synthesized materials I have extensively used the following characterization several techniques:

- Single crystal X-ray diffraction;
- Powder X-ray diffraction;
- Nuclear magnetic resonance of different nucleous (H, Na, Si, V, Nb);
- Scanning electron microscopy;
- Thermogravimetric analysis;
- Adsorption measurements;
- Raman, Infra-red and diffuse reflectance ultraviolet-visible spectroscopies;
- Magnetic measurements;
