Summary Novel sophisticated technologies that exploit the laws of quantum physics form a cornerstone for the future well-being, economic growth and security of Europe. Here photonic devices have gained a prominent position because the absorption, emission, propagation or storage of a photon is a process that can be harnessed at a fundamental level and render more practical ways to use light for such applications. However, the interaction of light with single quantum systems under ambient conditions is typically very weak and difficult to control. Furthermore, there are quantum phenomena occurring in matter at nanometer length scales that are currently not well understood. These deficiencies have a direct and severe impact on creating a bridge between quantum physics and photonic device technologies. aQUARiUM, precisely address the issue of controlling and enhancing the interaction between few photons and rolled-up nanostructures with ability to be deployed in practical applications.
With aQUARiUM, we will take epsilon (permittivity)-near-zero (ENZ) metamaterials into quantum nanophotonics. To this end, we will integrate quantum emitters with rolled-up waveguides, that act as ENZ metamaterial, to expand and redefine the range of light-matter interactions. We will explore the electromagnetic design freedom enabled by the extended modes of ENZ medium, which “stretches” the effective wavelength inside the structure. Specifically, aQUARiUM is built around the following two objectives: (i) Enhancing light-matter interactions with single emitters (Enhance) independent of emitter position. (ii) Enabling collective excitations in dense emitter ensembles (Collect) coherently connect emitters on nanophotonic devices to obtain coherent emission.
aQUARiUM aims to create novel light-sources and long-term entanglement generation and beyond. The envisioned outcome of aQUARiUM is a wholly new photonic platform applicable across a diverse range of areas.

Summary To satisfy our growing energy demand while reducing reliance on fossil fuels, a switch to renewable energy sources is vital. The intermittent nature of the latter means innovations in energy storage technology is a key grand challenge. Cost and sustainability issues currently limit the widespread use of electrochemical energy storage technologies, such as lithium ion and redox flow batteries. As the scale for energy storage is simply enormous, the only option is to look for abundant materials. However, compounds that fulfil the extensive requirements entailed at low cost has yet to be reported. While it is possible that the holy grail of energy storage will be found, for example by advanced computational tools and machine learning to design “perfect” abundant molecules, a more flexible, innovative solution to sustainable and cost-effective large-scale energy storage is required. Bi3BoostFlowBat will develop game changing strategies to widen the choice of compounds utilizable for batteries to simultaneously satisfy the requirements for low cost, optimal redox potentials, high solubility and stability in all conditions. The aim of this project is to develop cost-efficient batteries by using solid boosters and by eliminating cross over. Two approaches will be pursued for cross-over elimination 1) bio-inspired polymer batteries, where cross-over of solubilized polymers is prevented by size-exclusion membranes and 2) biphasic emulsion flow batteries, where redox species are transferred to oil phase droplets upon charge. Third research direction focuses on systems to maintain a pH gradient, to allow operation of differential pH systems to improve the cell voltages. Limits of different approaches will be explored by taking an electrochemical engineering approach to model the performance of different systems and by validating the models experimentally. This work will chart the route towards the future third generation battery technologies for the large-scale energy storage.

Project Books of the Medieval Parish Church

Host Institution (HI) HELSINGIN YLIOPISTO
Country Finland
Call Details Starting Grant (StG), SH6, ERC-2020-STG
Summary Book production became a market-orientated craft long before the invention of printing. In the late-medieval manuscript economy, the parish churches formed one of the biggest entities on the demand side. However, at present we know next to nothing about how they were provisioned with books. BOMPAC is a response to this gap in scholarly understanding. It offers the first substantial study of the place of the parish church in the culture and economy of the manuscript book, c. 1150–c.1500.
BOMPACs contribution to the topic will be twofold. It will, firstly, provide an extensive case study concering one medieval kingdom – Sweden – comprising more or less two modern countries (Sweden, Finland). Secondly, preliminary research indicates that many of the books used in the parishes of medieval Sweden were imported from abroad. Thus, the project will directly break new ground in the study of the international book economy of the later middle ages.
Parish church book provision remains poorly known because such books very rarely survive as complete physical items. BOMPAC will go around this limitation by innovative use of a hitherto understudied corpus of manuscript fragments. In Sweden, the parchment books of the parishes were recycled as covers for tax accounts in the sixteenth and seventeenth centuries. This operation was systematic and resulted in a massive collection of c. 50 000 leaves from c. 12 500 books, probably the biggest collection of material from medieval parish church books anywhere in the world.
Only recent cataloguing and digitizing efforts have made this material accessible for research. In BOMPAC, it will be studied with both statistical and palaeographical methods. A database-driven approach is used to produce a reliable big picture of how the books were distributed in the medieval period. Palaeographical and codicological case studies will show us the modes and routes by which parish churches acquired their books.

Call Details Starting Grant (StG), PE8, ERC-2018-STG
Summary The demand for donated organs vastly outnumbers the supply, leading each year to the death of thousands of people and the suffering of millions more. Engineered tissues and organs following Tissue Engineering approaches are a possible solution to this problem. However, a prevascularization solution to irrigate complex engineered tissues and assure their survival after transplantation is currently elusive. In the human body, complex organs and tissues irrigation is achieved by a network of blood vessels termed capillary bed which suggests such a structure is needed in engineered tissues. Previous approaches to engineer capillary beds reached different levels of success but none yielded a fully functional one due to the inability in simultaneously addressing key elements such as correct angiogenic cell populations, a suitable matrix and dynamic conditions that mimic blood flow.
CapBed aims at proposing a new technology to fabricate in vitro capillary beds that include a vascular axis that can be anastomosed with a patient circulation. Such capillary beds could be used as prime tools to prevascularize in vitro engineered tissues and provide fast perfusion of those after transplantation to a patient. Cutting edge techniques will be for the first time integrated in a disruptive approach to address the requirements listed above. Angiogenic cell sheets of human Adipose-derived Stromal Vascular fraction cells will provide the cell populations that integrate the capillaries and manage its intricate formation, as well as the collagen required to build the matrix that will hold the capillary beds. Innovative fabrication technologies such as 3D printing and laser photoablation will be used for the fabrication of the micropatterned matrix that will allow fluid flow through microfluidics. The resulting functional capillary beds can be used with virtually every tissue engineering strategy rendering the proposed strategy with massive economical, scientific and medical potential

Host Institution (HI) CENTRO DE ESTUDOS SOCIAIS
Country Portugal
Call Details Starting Grant (StG), SH6, ERC-2016-STG
Summary Colonial-Liberation Wars generate plural memories, conflicting evocations and persisting amnesias. The project’s main challenge is to produce innovative knowledge about the memories of the wars fought by the Portuguese state and pro-independence African movements between 1961 and 1974/5. The approach chosen is simultaneously diachronic and comparative, inasmuch as it contrasts changes that took place between the end of the conflicts and nowadays, regarding how wars, colonial pasts and anticolonial legacies have been remembered and silenced in Portugal, Angola, Mozambique, Guinea-Bissau, Cape Verde and São Tomé and Principe. The key hypothesis is that wars - as pivotal moments that ended the cycle of Empire in Portugal and started the cycle of African independences in the former Portuguese colonies - triggered memorialisation and silencing processes which had their own historicity.
CROME is divided into two strands. The first one, named ‘Colonial Wars, Postcolonial States’, looks at the role played by the states under consideration in mobilising, articulating and recognising the past, but also in actively generating selective representations. ‘Memory as a battlefield’ is the second strand, which will highlight distinct uses of the past and dynamics between social memories and individual memories.
The project intends to demonstrate how wars gave rise to multiple memories and conflicting historical judgements, mostly in Portugal, but also to examine how the specific nature of the (post-)colonial histories of each African country has generated different ways to summon war memories and (anti-)colonial legacies. CROME will, thus, put forward a ground-breaking perspective in terms of colonial-liberation war studies, and will be instrumental in dealing with such traumatic experience, for its comparative approach might help overcoming everlasting constraints still at play today, caused by the historical burden European colonialism left behind.

Call Details Starting Grant (StG), SH6, ERC-2017-STG
Summary The project will create new methodology for identification and interpretation of animal domestication, with a case study pertaining to reindeer domestication among the indigenous Sámi in northern Fennoscandia. Identification of early animal domestication is complicated due to the limited human control over the animals’ life cycles in early stages of domestication, leading to difficulties in interpreting morphological and genetic data, as well as in using traditional concepts and definitions of domestication. These problems are especially pressing in the study of reindeer domestication, characterized by very limited human control over animals. However, understanding reindeer domestication is important to local communities as well as to the scientific community due to central role of human-reindeer relation as a carrier of culture and identity among many peoples, including Sámi of northern Fennoscandia.
As a novel approach, we propose a focus on interactional events between humans and animals as indications of domestication taking place. We will create methods aimed at identifying interactional events such as draught use and feeding, between reindeer and humans. The methodological package includes physical activity reconstruction through entheseal changes, pathological lesions and bone cross-sections, and analysis of stable isotopes as indicator of animal diet. These methods will then be applied for archaeological reindeer bone finds and the results will be checked against aDNA data to examine changing human-animal relationships among the Sámi. The project has a potential to break new ground in understanding animal domestication as human-animal interaction, a viewpoint pivotal in today’s human-animal studies. Moreover, the project has potential of methodological breakthroughs and creation of transferable methodology. The results will be relevant to local communities and researchers dealing with domestication, human-animal studies and colonial histories.

Call Details Starting Grant (StG), SH6, ERC-2018-STG
Summary Dunes are now protected environments, being top priority for coastal managers, because of their important role as coastal defences. But, it was not like that in the past.
For centuries dunes were considered unproductive and dangerous. The sand blown by the wind was taken inland, invading fields, silting rivers and destroying villages. In the eighteenth century, a strategy was developed to fight against the dunes: trapping them with trees, with the double purpose of preventing the destruction of arable land and increasing their economic value converting them into forest areas. Different governments, in different countries supported the immobilization of the shifting sands. The strategy, developed in Europe, was taken to other places in the world. These works caused profound changes in vast coastal areas transforming arid landscapes of sandy dunes into green tree forests.
This project aims to explore human-environment relations in coastal areas worldwide, since the eighteenth century until today, through the study of dunes as hybrid landscapes. Based on selected case-studies and comparative approaches, the project will focus on the origins, reasons and means of dunes afforestation; the impacts of the creation of new landscapes to local communities and ecosystems; and the present situation of dunes as coastal defences and rehabilitated environments. The final purpose is to produce an innovative global history of coastal dunes, combining knowledges from both Humanities and Social Sciences and Physical and Life Sciences, which has never been done.
Supported by an interdisciplinary team, this research will result in new developments in the field of the Environmental History studies; provide relevant knowledge considering the need of efficient management solutions to adapt to the expected mean sea level rise; and stimulate environmental citizenship by disseminating the idea that the future of the world coasts depends on today’s actions.

Summary "The aim of the proposed research is to study electric-field induced magnetic phenomena in thin-film ferromagnetic-ferroelectric heterostructures. In particular, the project addresses ferroic order competition and magnetoelectric coupling dynamics at micro, nano, and atomic length scales.
The first part of the project focuses on the dynamics of coupled ferromagnetic-ferroelectric domains and electric-field induced magnetic domain wall motion at sub-nanosecond time scales. For simultaneous imaging of both ferroic domain responses to ultra-short electric-field pulses, the construction of a time-resolved polarization microscope is proposed. The second part relates to finite-size scaling of ferroic domain correlations in continuous films and electric-field control of magnetic effects in patterned nanostructures. Here, the aim is to elucidate the competition between magnetoelectric coupling at ferromagnetic-ferroelectric interfaces and the relevant energy scales within the bulk of ferroic materials. Moreover, electric-field induced domain wall motion in magnetic nanowires is pursued as a viable low-power alternative to current-driven spin-torque effects. Finally, the third part of E-CONTROL aims at visualization of magnetoelectric coupling effects with atomic precision. For this frontier study, the development of in situ transmission electron microscopy (TEM) techniques is proposed. The new measurement method enables the application of local electric fields on cross-sectional specimen during TEM analysis and this is bound to provide unique insights in strain-mediated and charge-modulated coupling mechanisms between ferromagnetic and ferroelectric thin films."

Call Details Starting Grant (StG), PE8, ERC-2012-StG_20111012
Summary Flows of complex fluids, such as many biological fluids and most synthetic fluids, are common in our daily life and are very important from an industrial perspective. Because of their inherent nonlinearity, the flow of complex viscoelastic fluids often leads to counterintuitive and complex behaviour and, above critical conditions, can prompt flow instabilities even under low Reynolds number conditions which are entirely absent in the corresponding Newtonian fluid flows.
The primary goal of this project is to substantially expand the frontiers of our current knowledge regarding the mechanisms that lead to the development of such purely-elastic flow instabilities, and ultimately to understand the transition to so-called “elastic turbulence”, a turbulent-like phenomenon which can arise even under inertialess flow conditions. This is an extremely challenging problem, and to significantly advance our knowledge in such important flows these instabilities will be investigated in a combined manner encompassing experiments, theory and numerical simulations. Such a holistic approach will enable us to understand the underlying mechanisms of those instabilities and to develop accurate criteria for their prediction far in advance of what we could achieve with either approach separately. A deep understanding of the mechanisms generating elastic instabilities and subsequent transition to elastic turbulence is crucial from a fundamental point of view and for many important practical applications involving engineered complex fluids, such as the design of microfluidic mixers for efficient operation under inertialess flow conditions, or the development of highly efficient micron-sized energy management and mass transfer systems.
This research proposal will create a solid basis for the establishment of an internationally-leading research group led by the PI studying flow instabilities and elastic turbulence in complex fluid flows.

Summary Recent events, from the anti-vaccination movement, to Brexit and even to mob killings, have raised serious concerns about the influence of the so-called fake news (FN). False information is not new in human history, but the recent surge in online activity, coupled with poor digital literacy, consumer profiling, and large profits from ad revenues, created a perfect storm for the FN epidemic, with still unimaginable consequences.
This challenge is interdisciplinary and requires academic research to guide current calls for action issued by academics, governmental and non-governmental agencies, and the social network platforms themselves. FARE will enrich current efforts, which mostly confront FN spreading from an applied perspective, by offering a theoretical framework that allows to make testable predictions. FARE argues that sharing of FN is a deviation from pure rationality and brings together 1) state of the art knowledge in behavioural psychology, to assess the role that cognitive biases play in susceptibility to FN, and 2) current models in network science and epidemiology, to test whether FN spread more like simple or complex contagions. Finally, fully recognizing that these novel big-data approaches carry great risks, FARE will develop a new strategy, mostly based on distributed computing, and guidelines to the ethical handling of human-related big-data.
Together, FARE will offer a comprehensive model to ask questions such as: 1) What role(s) cognitive biases play in FN spreading? 2) How does network architecture affect FNs spread? 3) How do biases and position on networks build on each other to impact propagation? 4) What monitoring and mitigation interventions are likely to be more efficient?
Moreover, the study of FN from such a conceptual perspective has the potential to profoundly increase our knowledge on human behaviour and information spread, beyond specific problems, with implications for communication (science, political), economics, and psychology.
Summary
Recent events, from the anti-vaccination movement, to Brexit and even to mob killings, have raised serious concerns about the influence of the so-called fake news (FN). False information is not new in human history, but the recent surge in online activity, coupled with poor digital literacy, consumer profiling, and large profits from ad revenues, created a perfect storm for the FN epidemic, with still unimaginable consequences.
This challenge is interdisciplinary and requires academic research to guide current calls for action issued by academics, governmental and non-governmental agencies, and the social network platforms themselves. FARE will enrich current efforts, which mostly confront FN spreading from an applied perspective, by offering a theoretical framework that allows to make testable predictions.
