Research Area

E. Bernardo is interested at the development of ceramic materials based on glass, recycled or derived from natural and industrial waste, or based on preceramic polymers and inorganic fillers. In the field of glass-based materials, E. Bernardo deals with new engineering products, mainly obtained through viscous flow sintering, such as sintered glass-ceramics, glass-matrix and glass-ceramic composite materials, cellular glasses and glass-ceramics. The most recent updates concern, as an alternative, the alkali activation of glasses, for dense and porous product manufactured at nearly room temperature. The activity is supported by numerous national and international collaborations. In particular, E. Bernardo is the reference person for the research unit of the University of Padua, in the European projects “CoACH” (“Advanced glasses, Composites And Ceramics for High growth Industries European Training Network", H2020-MSCA grant agreement no. 642557), "New-MINE" ("EU Training Network for Resource Recovery Through Enhanced Lanfill Mining", H2020-MSCA grant agreement no. 721185) e "FunGlass" ("Centre for Functional and Surface Functionalized Glass", H2020-Widespread Teaming Phase 2 grant agreement no. 739566). The research unit of the University of Padua is in charge of work packages specifically dedicated to the reuse of different types of waste in eco-sustainable ceramic materials. E. Bernardo also deals with glass-ceramic materials for applications in tissue engineering (in the form of foams or three-dimensional scaffolds), starting from glasses or from preceramic polymers, containing micro- and nano-particles as active fillers. In addition to bioactive silicates, the latest research includes advanced ceramic materials, silicates or silicon oxy-nitrides (SiAlON ceramics), with various international collaborations.

Thesis proposals

- Sustainable building materials from alkaline activation of waste glass
Glass recycling can only be implemented through a scrap purification phase. The purified fraction is effectively adopted as the secondary raw material. The residual fraction, mostly in the form of fine powders, is instead difficult to place, due to the concentration of heterogeneities (metallic, polymeric and ceramic particles). The research (with the possibility of collaborations with companies) involves the use of non-recyclable powders, suspended in alkaline solutions. The chemical attack determines the gelation of the suspensions, due to condensation reactions on the surface of the particles, with progressive drying (<100 °C). Glass powders, possibly modified with ceramic scraps, are transformed into innovative, dense (for the replacement of bricks or natural stones) or porous (for thermal and acoustic insulation) building materials.
- Multifunctional materials from inorganic waste supported by alkaline activation
The aforementioned alkaline activation process can be extended, from 'non-recyclable' fractions of glass cullet, to mixtures containing industrial and natural residues (metallurgical slag, ceramic fibers from decommissioned insulation, incineration residues of municipal solid waste, volcanic ashes). The research, again also with industrial collaborations, is aimed both at obtaining chemically stable materials (i.e. capable of retaining pollutants indefinitely) and at exploitation in the context of constructions and beyond. In particular, waste-derived materials may be as 'sorbents' of organic pollutants in wastewater
- Innovative photocatalytic materials based on waste glass
The alkaline activation of glass powders can be exploited in the field of additive manufacturing. Suspensions can be used as inks in the printing of porous structures by direct extrusion (direct ink writing); alternatively, porous structures (from SLA printing of glass and photosensitive resins) can be subjected to alkaline activation after sintering. The hierarchical porosity structure maximizes the absorption of organic pollutants. The degradation of the adsorbed substances is possible through the dispersion of nanoparticles (TiO2 or Fe3O4) in the activating alkaline solutions.
- Additive manufacturing of scaffolds for bone tissue engineering starting from innovative raw materials (cooperation with Dr. Hamada Elsayed, hamada.elsayed@unipd.it)
Innovative silicate bioceramics are easily obtained from the reaction of fillerized silicone matrices with oxides; complex topology scaffolds derive from stereolithography of the mixtures, modified with photosensitive resins. Micro- and nano-metric fillers in powder form can be replaced by dispersions of molten salts, in emulsion in the silicone/photosensitive resin mixtures.
- Innovative dielectric coatings on metallic conductors, based on pre-ceramic polymers
Silicones and fillers can be deposited on metallic conductors, in order to configure innovative dielectric coatings. The research, also in collaboration with a company, is aimed at manufacturing coatings capable of withstanding over 500 °C, acconding to the ceramic transformation of the silicone/oxide mixtures.
