    Specialist areas of interest

    Dr. Feteira's research focuses simultaneously on the establishment of composition-structure-property relationships in new advanced functional oxides, and on the fabrication of prototype devices via 3D integration of these materials. His work in this area has developed through a series of pure and applied projects, several of which have involved direct collaboration with industrial groups (TDK EPC, AVX Ltd, Morgan Electroceramics, Powerwave Ltd, Straumann). His latest research has focused on bandgap engineering of ferroelectrics for solar energy harvesting and environmentally friendly Pb-free piezoelectric actuators and energy storage devices. In the area of biomaterials he works on glass-ceramics for dental applications,

    The geographical location of Brazil combined with its large Niobium and Iron reserves are the two main motivations for this project. First, Brazil is a country located mostly in the intertropical region. Values of global solar radiation incidence on any region of Brazil (4200-6700 kWh.m-2) are higher than in most European Union countries such as Germany (900-1250 kWh.m-2), France (900 -1650 kWh.m-2) and Spain (1200-1850 kWh.m-2), where projects focused on solar energy harvesting, some relying on strong government incentives, are widely disseminated. Hence, solar energy is one of the most promising sources of renewable, clean energy to replace the current dependence on fossil fuels. Nevertheless, to make solar energy viable, it is necessary to find inexpensive and non-toxic photovoltaic materials that can efficiently convert solar radiation into electricity. Crystalline silicon has long been the most widely employed photovoltaic material, with cells now achieving 25% efficiency. However, these cells are expensive to produce and operate - the unit cost of energy produced from a Si solar cell is nearly 4 times that of energy produced from fossil fuels. Conventional solid-state photovoltaics also suffer a limitation in that their maximal photovoltages are set by the relevant semiconductor electronic band gaps. These photovoltages, which are established at semi-conductor junctions, are used to separate the electron-hole pairs generated when light is first absorbed by the photovoltaic material. Optical band gaps of ferroelectrics can be tailored into the visible region while preserving their intrinsically high spontaneous polarisation, which then will enable their use in the fabrication of non-expensive, clean and efficient solar cells. Hence, the overall aim of this project is the establishment of the underlying mechanisms that control the band gap in KNbO3 ferroelectrics with robust polarisation. The proposed research is also guided by sustainability criteria in terms of the choice of non-toxic and non-expensive raw materials available in Brazil, and it combines ideas from defect chemistry in ferroelectrics, local distortions to the average crystal structure and their impact in orbital overlapping, size effects and domain wall dynamics. In summary, it is focused on the understanding of different parameters that may be employed in band gap engineering of ferroelectrics.

    October 2014-October 2015 “Mechanical properties of glass ceramics for dental applications” Funded by CNPq (Brazil) PDRA: Dr. L. Lauro Lima

    Every year millions of people seek dental treatment in order to either repair damaged, unaesthetic and dysfunctional teeth or to replace missing natural teeth. This treatment is driven by the simultaneous pursuit of rehabilitation of the oral functions and improvement of the oral aesthetics. Several dental materials have been developed to meet the stringent requirements in terms of mechanical properties (strength, fracture toughness and wear resistance), aesthetics (colour, translucency) and chemical durability in the oral environment. In addition, commercial prosthetic dental materials are also required to be compatible with computer aided design–computer aided manufacture (CAD/CAM) technology. Indeed, CAD/CAM technology is used in the fabrication of several dental prosthetic restorations such as inlays, onlays, veneers, crowns, fixed partial dentures and implant abutments. Such fabrication can take place either at the dentist’s chairside or away in a dental laboratory.

    In this project the mechanical properties of lithium aluminodissilicate glass-ceramics will be evaluated and dental crowns will be manufactured.

    Output: Successful manufacture of crowns suitable for application. Work presented the 7th World Congress on Biomechanics. 2 publication under preparation. A new PhD student join the group to further investigate LAS glasses.

    Piezoelectric devices are mainly fabricated from ceramics based on Pb(Zr,Ti)O3, because this compound exhibits unrivalled large field-induced strains with little temperature dependence. Recent European legislation regulating the use of hazardous materials in electronic equipment has call for the substitution of Pb(Zr,Ti)O3-based devices by environmental friendly alternatives, as soon they become scientifically and technically practicable. Hence, Pb-free piezoceramics will replace Pb(Zr,Ti)O3-based ceramics, in applications such as pressure sensors, actuators, ultrasonic transducers. In collaboration with the Graz University of Technology, we reported a large field-induced strain in (Bi0.5Na0.5)TiO3-SrTiO3 based ceramics, which drops suddenly at 160°C due to depolarisation. Origins of this large strain and depolarisation are not understood yet; however they can be clarified by the characterisation of the intrinsic and extrinsic contributions to the strain.
