    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.

    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.

    The S-CAGE project aims to develop a new generation of crystalline solids with periodically-organized discrete voids, or compartments, that would benefit from the combination of the high stability and robustness of dense materials with the structural diversity and versatility (and therefore large applicability) of open frameworks. These coordination polymers (CPs) will be capable of interacting with guest species in the absence of large channels or permanent pores due to the presence of dynamic entrances. This could open new horizons towards the design of unprecedented materials as an enhanced interplay between the guests and the frameworks will be achieved resulting from the confined space of the compartmentalized pockets. The main goals of S-CAGE will be: i) Chemical design of compartmentalized 1D, 2D and 3D coordination polymers. These materials will be designed in such a way that they will provide ideal room to accommodate different guest molecules, which can be easily tuned depending on the target guest. ii) Advanced structural characterization, including modern diffraction studies under pressure of gas and volatile guests. This strategy will provide unequivocal prove of the location of the guest molecules in the internal voids and gain insights of the mechanism of entrance. The direct visualization of the modes of interactions of different gases will permit a deep comprehension of the nature of their interaction. iii) Gas separation studies. My goal will be the development of materials that could specially serve for gas separation and improve the performances of zeolites and MOFs by implementation of dynamic entities into the framework. iv) Sensing capabilities through changes in magnetic properties. The chemical design followed in S-CAGE will result in magnetic CPs with confined spaces which should enhance the interaction of the guest molecules with the framework, and thus a change in their magnetism is expected.

    Sexual conflict is essential to understand phenotypic evolution in promiscuous species. Yet we know very little about how it operates in the wild and how ecology may help explain the overwhelming variation in sexual traits showcased in nature. I propose an ambitious multi-disciplinary approach combining phenotypic-level measurements with transcriptomic and proteomic tools to study the ecological factors that underlie variation in sexual conflict in Drosophila melanogaster, at a global ecological scale. This is a powerful system because: a) it has a global distribution that spans marked ecological variation, b) it exhibits intense sexual conflict including well studied pre- and post-copulatory traits, c) its sexual conflict traits have been shown to harm females and decrease population viability, d) it affords the use of state-of-the-art molecular techniques and e) despite being a model organism in sexual selection and sexual conflict studies, we know very little about the role of ecology. I will study 1) how temperature, population density, sex ratio and habitat characteristics modulate sexual conflict across different levels of sexual selection (i.e. pre-copulatory vs. post-copulatory) and genetic conflict (i.e. intra-locus vs. inter-locus sexual conflict), 2) the role of phenotypic plasticity and local adaptation in shaping sexual conflict responses to temperature, 3) how this may impact population viability, and 4) the physiological and genetic mechanisms underlying variation in sexual conflict. Given the novelty and reach of the questions addressed this action represents an important advance in our understanding of how sexual conflict evolves and operates in nature, as well as the consequences in terms of potential eco-evolutionary feedback on population viability. Understanding the latter can be particularly relevant to predict the fate of populations and species facing directional environmental changes, such as those imposed by global warming.
