Summary 2D-PnictoChem aims at exploring the Chemistry of a novel class of graphene-like 2D layered
elemental materials of group 15, the pnictogens: P, As, Sb, and Bi. In the last few years, these materials
have taken the field of Materials Science by storm since they can outperform and/or complement graphene
properties. Their strongly layer-dependent unique properties range from semiconducting to metallic,
including high carrier mobilities, tunable bandgaps, strong spin-orbit coupling or transparency. However,
the Chemistry of pnictogens is still in its infancy, remaining largely unexplored. This is the niche that
2D-PnictoChem aims to fill. By mastering the interface chemistry, we will develop the assembly of 2Dpnictogens
in complex hybrid heterostructures for the first time. Success will rely on a cross-disciplinary
approach combining both Inorganic- and Organic Chemistry with Solid-state Physics, including: 1)
Synthetizing and exfoliating high quality ultra-thin layer pnictogens, providing reliable access down to
the monolayer limit. 2) Achieving their chemical functionalization via both non-covalent and covalent
approaches in order to tailor at will their properties, decipher reactivity patterns and enable controlled
doping avenues. 3) Developing hybrid architectures through a precise chemical control of the interface,
in order to promote unprecedented access to novel heterostructures. 4) Exploring novel applications
concepts achieving outstanding performances. These are all priorities in the European Union agenda
aimed at securing an affordable, clean energy future by developing more efficient hybrid systems for
batteries, electronic devices or applications in catalysis. The opportunity is unique to reduce Europe’s
dependence on external technology and the PI’s background is ideally suited to tackle these objectives,
counting as well on a multidisciplinary team of international collaborators.

Project Electrical control of magnetism in multiferroic 2D materials

Summary The avenue of magnetism in the field of 2D materials has marked the ultimate milestone in the discovery of one-atom-thick classes of materials. Bulk ferromagnets and antiferomagnets now have their 2D counterparts and are at one’s provision for the realization of imagination-limited artificial layered structures. At the same time, this awaited breakthrough has brought in new conundrums that demand investigation. This project is driven by the exploration of the limits of van der Waals 2D magnets from both a fundamental physics and a materials science and devices point of view. Firstly, it addresses fundamental key questions regarding spin order at the true 2D limit, which remain a mystery to the date. Here, the great variety of magnetic anisotropies exhibited by the transition metal halides will shed new light to the subtle equilibrium of interactions in few-layer magnets. Secondly, the project will invoke the control of the magnetic ground states and spin textures in true 2D magnets via electrical manipulation. Electric fields will assist in tuning the magnetic coupling and critical behaviour and the spatial manipulation of spin topologies. Anticipated breakthroughs will be the enhancement of the critical temperature in semiconducting single layer magnets towards room temperature 2D magnetism and the realization of single-layer multiferroic 2D materials. Thirdly, the field effect electrical control of magnetism in designer van der Waals and lateral heterostructures will allow for an enhanced magneto-electric coupling, yielding functional devices for effective charge-to-spin transduction that hold promise in spintronics. The proposal will achieve success by an integral approach to research, through the combination of the study of solid-state growth techniques together with the implementation of state-of-the-art deterministic manipulation of 2D materials in inert conditions and the use high resolution magnetism probes to test hybrid magnetic-optoelectronic devices.

Project acronym KryptonInt
Project Erasing the superintegron to understand the role of chromosomal integrons in bacterial evolution
Researcher (PI) Jose Antonio ESCUDERO
Host Institution (HI) UNIVERSIDAD COMPLUTENSE DE MADRID
Country Spain
Call Details Starting Grant (StG), LS2, ERC-2018-STG
Summary Integrons are genetic platforms that enhance bacterial evolvability through the acquisition and stockpiling of new genes encoded in mobile elements named cassettes. They are found in the chromosomes of environmental bacteria but some have acquired mobility through their association to transposons and conjugative plasmids. These mobile integrons (MI) caused the unexpected rise of multidrug resistance that is now a major threat to modern medicine, and are good proof of the adaptive power of integrons. Class 1 integrons are the most relevant MI and the major experimental model. Yet little is known about the hundreds of sedentary chromosomal integrons (SCI) that have driven bacterial evolution for eons. The paradigm of SCI is the superintegron (SI), an extremely large integron located in the chromosome of Vibrio cholerae, the causative agent of Cholera disease. Despite its role in the adaptability of one of the deadliest pathogens in history, the SI is poorly characterized because it is only functional in its native genetic background, yet its presence interferes with, and precludes all studies performed in V. cholerae. I propose to solve this paradoxical situation by deleting the SI, an ambitious project not only for its size (126 Kb) but because it is highly stabilized by 17 toxin-antitoxin systems. To do so, I have developed SeqDelTA, a novel method that is already giving excellent preliminary results. I will then use V. cholerae∆SI to study fundamental aspects of SCIs, yet out of reach. I will elucidate the functions encoded in SI cassettes to understand the role and adaptive value of integrons in nature; I will also unravel the genesis of cassettes: how a gene is exapted from its genetic context to become a mobile module; and I will explore the circulation of antibiotic resistance cassettes among humans, animals, food, and the environment with a novel biosynthetic tool (the I3C). KryptonInt will open and explore the historically inaccessible field of study of SCIs.

Project Population dynamics and cultural adaptations of the last Neandertals and first Modern humans in inland Iberia: a multi-proxy investigation
Researcher (PI) Manuel ALCARAZ-CASTAnO
Host Institution (HI) UNIVERSIDAD DE ALCALA
Country Spain
Call Details Starting Grant (StG), SH6, ERC-2018-STG
Summary The relations between cultural developments and environmental change among hunter-gatherers are crucial for studying population dynamics during the last glaciation (110,000–11,700 years ago). However, proposing solid interpretations on how climate and environment variability affected the social and techno-economic organisation of hominins, requires robust geoarchaeological, chronological, and palaeoecological evidence. In the Iberian Peninsula, a key area for this period due to its geographic position and ecological variability, models on these topics are biased by the poor quality of available evidence for its interior lands. The Iberian interior has been traditionally depicted as a marginal and few populated region due to its harsh ecological conditions compared to the coastal areas. Based on preliminary data suggesting that this picture could be wrong, I hypothesize (1) that the human settlement of interior Iberia during this period was more stable than previously thought and (2) that his has relevant implications at the European scale for problems such as the replacement of Neandertals by modern humans, the first modern human peopling of Europe, and the patterns of land use and mobility during the coldest stages of the last glacial. To test these hypotheses, this project will investigate population dynamics and human-environment interactions of the last Neandertals and first modern humans in interior Iberia based on completely unprecedented evidence gathered by means of a macro-regional and interdisciplinary research project. This involves the participation of a wide team of scholars coordinated by the PI, and a network of methods including field surveys, geoarchaeological excavations and chronometric, paleoecological, zooarchaeological, techno-economic and symbolic studies. The results will significantly change our views on key biocultural and ecological processes of the European prehistory, and the way human societies have dealt with challenging environments.

Project Exploiting the hypoxia response in T cells for Next-Generation Immuno-Oncology
Researcher (PI) Francisco de Asis PALAZON GARCIA
Host Institution (HI) ASOCIACION CENTRO DE INVESTIGACION COOPERATIVA EN BIOCIENCIAS
Country Spain
Call Details Starting Grant (StG), LS7, ERC-2018-STG
Summary NextGen_IO has a core focus on immuno-oncology, specifically on target discovery and drug development, to exploit several opportunities that the hypoxia pathway in T cells offers for the treatment of cancer. It is well recognised that the clinical response of immunotherapies depends on the ability of T-cells to mount an effective effector response, persist in treated patients and avoid exhaustion and toxicities. Several approaches to immunotherapy have shown promise in clinical trials, especially the use of immune checkpoint inhibitors and, more recently, autologous adoptive T-cell therapies. However, current state-of-the-art immunotherapies are only effective in a small fraction of patients, offering a medical need to be addressed in several cancer types. Importantly, the tumor microenvironment has specific features that impact the immune response, including decreased oxygenation, aberrant vascularization and altered nutrient availability; all these influence the success of immunotherapies. During the last 10 years, my research has been focused on elucidating the role of the oxygen sensing machinery in T cell function, and the link of hypoxia-driven metabolism and epigenetic modifications with T cell differentiation into effector and memory T cells within the context of cancer immunotherapy. The current proposal aims to exploit these previous findings with a multi-disciplinary strategy, to deliver several early-stage drug discovery outputs.
The main objectives are:
1. Development of a novel small molecule inhibitor to modulate the hypoxic response in T cells.
2. Therapeutic target discovery in T cells, focused on hypoxia-driven epigenetic modifications.
3. Development of hypoxia-inducible molecular switches for adoptive T cell therapy.
Successful completion of the project will allow me to further innovate and consolidate my position as a leader in this field, harness this pathway for therapeutic potential and explore potential combinatorial approaches.
