Metal-Organic-Frameworks (MOFs) offer appealing advantages over classical solids from combination of high surface areas with the crystallinity of inorganic materials and the synthetic versatility (unlimited combination of metals and linkers for fine tuning of properties) and processability of organic materials. Provided chemical stability, I expect combination of porosity with manipulable electrical and optical properties to open a new world of possibilities, with MOFs playing an emerging role in fields of key environmental value like photovoltaics, photocatalysis or electrocatalysis. The conventional insulating character of MOFs and their poor chemical stability (only a minimum fraction are hydrolytically stable) are arguably the two key limitations hindering further development in this context. With chem-fs-MOF I expect to deliver: 1. New synthetic routes specifically designed for producing new, hydrolytically stable Fe(III) and Ti(IV)-MOFs (new synthetic platforms for new materials). 2. More advanced crystalline materials to feature tunable function by chemical manipulation of MOF’s optical/electrical properties and pore activity (function-led chemical engineering). 3. High-quality ultrathin films, reliant on the transfer of single-layers, alongside establishing the techniques required for evaluating their electric properties (key to device integration). Recent works on graphene and layered dichalcogenides anticipate the benefits of nanostructuration for more efficient optoelectronic devices. Notwithstanding great potential, this possibility remains still unexplored for MOFs. Overall, I seek to exploit MOFs’ unparalleled chemical/structural flexibility to produce advanced crystalline materials that combine hydrolytical stability and tunable performance to be used in environmentally relevant applications like visible light photocatalysis. This is an emerging research front that holds great potential for influencing future R&D in Chemistry and Materials Science.

Graphene nanoribbons (NR) are quasi-1D nanostructures with discrete band gaps, ballistic conduction, and one-atom thickness. Such properties make them ideal candidates to develop low-dimensional semiconductors, which are essential components in nanoelectronics. Atomically-precise control over the structure of NR (width, length, edge, doping) is crucial to fully exploit their potential. However, current approaches for the synthesis of NR suffer from several drawbacks that do not allow attaining such level of precision, therefore alternative methods need to be sought. e-Sequence will develop an unprecedented approach that assembles stepwise small molecular building blocks into NR to specifically target the most important challenges in NR synthesis. Such approach will enable the preparation of an unlimited number of NR with atomically-precise control over their structure and with almost no synthetic and purification effort, exceeding the limits of existing methods. The impact of e-Sequence will not be limited to NR synthesis but it will also extend to other disciplines, since NR are promising candidates to develop new technologies with applications in electronics, sensing, photonics, energy storage and conversion, spintronics, etc. e-Sequence ambitious research programme will be orchestrated by an independent scientist with an excellent track record of achievements in low-dimensional carbon nanostructures, and who has already established a fledgling and internationally competitive research group. Building on this and on his recent permanent appointment as Research Professor, the award of this ERC project will enable him to consolidate his group, build a portfolio of excellent research, and produce results that compete on the world stage.

Life history is the nexus of biology, because various biological questions ultimately revolve around the causes and consequences of variation in reproduction and survival, i.e. fitness. Traditionally, a major tool in life-history research has been quantitative genetics because it provides an important statistical link between phenotype and genotype. However, the mechanisms by which evolution occurs may remain unclear unless such traditional approaches are combined with molecular investigations. Another complicating factor is that the fitness of male vs female life histories do not always align, and hence life history traits may be shaped by sexual conflict. This is why life-history approaches focusing on both quantifying the conflict and understanding its resolution at the genetic level are needed. As in many species, age at maturity in Atlantic salmon is tightly linked with size at maturity and thus represents a classic evolutionary trade-off: later maturing individuals spend more time at sea before returning to freshwater to spawn and have higher reproductive success due to their larger size but also have a higher risk of dying prior to first reproduction. Our recent cover paper in Nature reported a large-effect gene explaining 40% of the variation in this key life history trait. Remarkably, the locus exhibits sex-dependent dominance and this resolves a potential intra-locus sexual conflict in the species. The relatively simple genetic architecture of this trait combined with the features of Atlantic salmon as a model system offer an ideal opportunity to better understand the molecular mechanisms and ecological drivers underlying a locally adapted life history trait. In MATURATION I will i) characterize age at maturity candidate gene functions and allelic effects on phenotypes ii) elucidate fitness effects of these phenotypes and GxE interactions iii) develop a mechanistic model for the sex-dependent dominance and validate intra-locus sexual conflict resolution

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.
