    Metal-Organic Frameworks (MOFs) – porous materials with almost unlimited chemical and structural diversity - have incited an interesting alternative to the drawbacks that nanotechnology is currently facing. The defect engineering of MOFs has been used as a tool to modify their porosity, chemical reactivity and electronic conductivity among other properties, but research is still limited in the vast majority towards Zr-MOFs. Notably, defect chemistry of Ti-MOFs remains unexplored despite that the pristine materials photoactivity, chemical and structural stability and Titanium being an abundant biocompatible metal. This project, entitled `Defective Titanium Metal-Organic-Frameworks(DefTiMOFs)’ aims to develop novel high-throughput (HT)synthetic methodologies for the control of not only defect chemistry of Ti-MOFs,but also of their particle size and inner surface (porefunctionalisation) towards the controllable modification of their properties. HT synthesis will be convened with a set of novel characterisation techniques (mainly synchrotron-based) for atomic and molecular level of characterisation of defects, aiming to correlate synthetic conditions with defect formation (defect type, densityand spatial distribution within the framework)in order to provide thebase of knowledge to anticipate their properties based on the synthetic conditions. This will then allow for defect engineering of MOFs using a wide range of materials. In view of the above and inspired by the high demand for clean and renewable energy sources including efficient and affordablewater delivery systems in places with limited access to drinkablewater, the DefTiMOFs project aims to correlate defect chemistry of Ti-MOFs with their performance towards environmentally friendly applications. This will lead to the ultimate design of materials with outstanding performance in heterogeneous catalysis, photocatalysis (hydrogen production) and water harvesting from air.

    Overall Budget: 150,000 EURFunder Contribution: 150,000 EUR

    The purpose of Hy-MAC is to assess both technical and economic viability of using magnetic nanocomposites based on the combination of carbon nanoforms (graphene) with magnetic nanoparticle as hybrid supercapacitors. These hybrid magnetic materials have shown to exhibit unique supercapacitive properties, which can be significantly enhanced by application of an external magnetic field. Thus, the specific capacitance increases up to a 500% by applying an external magnetic field. Taking advantage of these results, in this proposal we plan to fabricate and test prototype supercapacitive devices exhibiting better performances than those reported for commercial supercapacitors.

    Overall Budget: 170,122 EURFunder Contribution: 170,122 EUR

    Future smart multi-functional logic devices might combine switchable molecules and two-dimensional layered materials (2D-LMs). Spin crossover (SCO) compounds are a paradigmatic example of molecular switches including cooperative spin-transitions. One of their hallmarks is the huge concomitant strain arising upon SCO up to 13 % responding to numerous external stimuli even above room temperature. Besides, hundreds of 2D-LMs were discovered after the isolation of thin graphene layer(s) from graphite. Such a plethora of diverse atomic layers with distinct properties opened the door to design novel van der Waals heterostructures (vdWHs) with artificially engineered functionalities. Introducing external interactions or strain can give the ability to tune optical band gaps and electrical properties of 2DLMs-vdWHs. Still in its infancy, this strategy promises new properties and exciting physics seeking thereafter unprecedented device performance and applications. This interdisciplinary project intends at pioneering design, preparation and investigations of the electrical transport and magnetotransport properties of SCO/2D-LMs-vdWHs. Signs of the coexistence, or even synergy, of several physical properties of interest will be painstakingly researched. This quest encompasses manifestations of magnetism, conductivity, and superconductivity influenced by thermal- and light-induced SCO cooperative spin-transitions, pursuing innovative 2D nanoelectronics, energy applications and flexible sensors.

    In Europe, around of 10 million of people are more than 65 years. Population ageing is one of the greatest social and economic challenges facing the EU. Projections foresee a growing number and share of elderly persons (aged 65 and over), with a particularly rapid increase in the number of very old persons (aged 85 and over) and increasing care need. The “Socio Economic deprivation related to effect of presence of Dependant older people: strategies for Innovative Policies in Europe” (SEreDIPE) project is focused on Socio Economic (SE) deprivation of family in relationship with Long Term Care. The study aims to evaluate the effects of the presence of elderly with social and health care need on the socio-economic status of the families, in order to understand what innovative initiatives, policies or strategies could be used to cope the negative effect for the families. The study proposes a comparison between eight European countries to cover the different care regimes used in Europe: Italy, Spain, Germany, Romania, Poland, Finland, Netherland, United Kingdom. The project uses a mixed quantitative and qualitative method. The multilevel quantitative analysis is aimed to find a statistical confirmation of the relationship, identifying its main descriptive characteristics, designing national and European scenarios. The qualitative analysis is aimed to find innovative strategies and policies (already existing or not) that should be implemented in each studied country and in Europe. The study involves experts, national stakeholders and policymaker, as interviewed or as participant in focus groups and workshops to promote an active technical and academic debate on issue.
