The Thematic Strand 3 comprises two major axes, Sustainability and Health.
1) SUSTAINABILITY axis is grounded on the implementation of the forest-based biorefinery, recycling of industrial
wastes and urban mining, and environmental remediation and water treatment, as follows.
- 'Biorefinery' related activities address the: characterization of agro-forest biomass; extraction of valuable components using benign processes; conversion of biomass components into platform chemicals/fine chemicals and biofuels, focusing on the development of efficient catalytic and biotechnological processes; development of novel polymeric materials based on biomass-derived monomers and new polysaccharide-based materials and composites, including functional materials bearing inorganic nanophases.
- 'Recycling and Urban Mining' focuses on the: recycling of industrial, agricultural and fisheries wastes for the production of new (bio)materials, electroceramics and magnetic materials by cost-effective processes; development of photocatalytic coatings for pollutants removal and antimicrobial activity; extraction of compounds from disposed drugs and waste foods; recovery of metals and rare-earths from electronic wastes.
- 'Environmental Remediation and Water Treatment' comprises: capture and conversion of CO2; use of novel adsorbents for pollution control, and water treatment; study of the toxicity and of the environmental impact of the novel materials prepared, and solvents developed or used in the process under study.
2) HEALTH axis encompasses the development of novel biomaterials for regenerative medicine, nanoparticles for in
vitro and in-vivo applications, drugs and drug delivery, and analytical tools for diagnosis, as follows.
- 'Biomaterials for Regenerative Medicine' develops: new osteoinductive materials based on calcium phosphates, bioactive glasses and glass-ceramics, new composite scaffolds polymer-nanostructured ceramics for tissue engineering hybrid organic-inorganic materials for biomedical applications; biodegradable polymeric films for tissue growth strategies, and piezoelectric polymer platforms for neural regenerative approaches.
- 'Nanoparticles for In-Vitro and In-Vivo Applications' covers the use of surface-modified nanostructures, multimodal nanoparticles and polymer nanocomposites for imaging, as hyperthermia mediators and photodriven applications.
- 'Drugs and Drug Delivery' addresses mainly the development of novel antitumoral drugs based on metallopharmaceuticals and the delivery of these and other drugs, either directly or by encapsulation in polysaccharides, glass polymer composites and microporous silicates.
- 'Analytical Tools' focuses on the use of metabolomics for assessing in vitro and in vivo interactions of (bio)materials with living organisms and for developing new clinical diagnosis methodologies.
