Summary This project aims at promoting sustainable combustion technologies for transport via validation of advanced combustion kinetic models obtained using sophisticated new laboratory experiments, engines, and theoretical computations, breaking through the current frontier of knowledge. It will focus on the unexplored kinetics of ignition and combustion of 2nd generation (2G) biofuels and blends with conventional fuels, which should provide energy safety and sustainability to Europe. The motivation is that no accurate kinetic models are available for the ignition, oxidation and combustion of 2G-biofuels, and improved ignition control is needed for new compression ignition engines. Crucial information is missing: data from well characterised experiments on combustion-generated pollutants and data on key-intermediates for fuels ignition in new engines.
To provide that knowledge new well-instrumented complementary experiments and kinetic modelling will be used. Measurements of key-intermediates, stables species, and pollutants will be performed. New ignition control strategies will be designed, opening new technological horizons. Kinetic modelling will be used for rationalising the results. Due to the complexity of 2G-biofuels and their unusual composition, innovative surrogates will be designed. Kinetic models for surrogate fuels will be generalised for extension to other compounds. The experimental results, together with ab-initio and detailed modelling, will serve to characterise the kinetics of ignition, combustion, and pollutants formation of fuels including 2G biofuels, and provide relevant data and models.
This research is risky because this is (i) the 1st effort to measure radicals by reactor/CRDS coupling, (ii) the 1st effort to use a μ-channel reactor to build ignition databases for conventional and bio-fuels, (iii) the 1st effort to design and use controlled generation and injection of reactive species to control ignition/combustion in compression ignition engines

Summary "This proposal develops a unified, underpinning technology to create novel, complex and biomimetic 3D environments for the control of tissue growth. As director of Cambridge Centre for Medical Materials, I have recently been approached by medical colleagues to help to solve important problems in the separate therapeutic areas of breast cancer, cardiac disease and blood disorders. In each case, the solution lies in complex 3D engineered environments for cell culture. These colleagues make it clear that existing 3D scaffolds fail to provide the required complex orientational and spatial anisotropy, and are limited in their ability to impart appropriate biochemical and mechanical cues.
I have a strong track record in this area. A particular success has been the use of a freeze drying technology to make collagen based porous implants for the cartilage-bone interface in the knee, which has now been commercialised. The novelty of this proposal lies in the broadening of the established scientific base of this technology to enable biomacromolecular structures with:
(A) controlled and complex pore orientation to mimic many normal multi-oriented tissue structures
(B) compositional and positional control to match varying local biochemical environments,
(C) the attachment of novel peptides designed to control cell behaviour, and
(D) mechanical control at both a local and macroscopic level to provide mechanical cues for cells.
These will be complemented by the development of
(E) robust characterisation methodologies for the structures created.
These advances will then be employed in each of the medical areas above.
This approach is highly interdisciplinary. Existing working relationships with experts in each medical field will guarantee expertise and licensed facilities in the required biological disciplines. Funds for this proposal would therefore establish a rich hub of mutually beneficial research and opportunities for cross-disciplinary sharing of expertise."

Summary This long-term research project is based on the data-mining of the Llibres d'Esposalles conserved at the Archives of the Barcelona Cathedral, an extraordinary data source comprising 244 books of marriage licenses records. It covers about 550.000 unions from over 250 parishes of the Diocese between 1451 and 1905. Its impeccable conservation is a miracle in a region where parish archives have undergone massive destruction. The books include data on the tax posed on each couple depending on their social class, on an eight-tiered scale. These data allow for research on multiple aspects of demographic research, especially on the very long run, such as: population estimates, marriage dynamics, cycles, and indirect estimations for fertility, migration and survival, as well as socio-economic studies related to social homogamy, social mobility, and transmission of social and occupational position. Being continuous over five centuries, the source constitutes a unique instrument to study the dynamics of population distribution, the expansion of the city of Barcelona and the constitution of its metropolitan area, as well as the chronology and the geography in the constitution of new social classes.
To this end, a digital library and a database, the Barcelona Historical Marriages Database (BHiMaD), are to be created and completed. An ERC-AG will help doing so while undertaking the research analysis of the database in parallel.
The research team, at the U. Autònoma de Barcelona, involves researchers from the Center for Demo-graphic Studies and the Computer Vision Center experts in historical databases and computer-aided recognition of ancient manuscripts. 5CofM will serve the preservation of the original “Llibres d’Esposalles” and unlock the full potential embedded in the collection.

Summary "This project explores the concept of agricultural spread as analogous to enforced climate change and asks how cereals adapted to new environments when agriculture was introduced into Europe. Archaeologists have long recognized that the ecological pressures placed on crops would have had an impact on the spread and subsequent development of agriculture, but previously there has been no means of directly assessing the scale and nature of this impact. Recent work that I have directed has shown how such a study could be carried out, and the purpose of this project is to exploit these breakthroughs with the goal of assessing the influence of environmental adaptation on the spread of agriculture, its adoption as the primary subsistence strategy, and the subsequent establishment of farming in different parts of Europe. This will correct the current imbalance between our understanding of the human and environmental dimensions to the domestication of Europe. I will use methods from population genomics to identify loci within the barley and wheat genomes that have undergone selection since the beginning of cereal cultivation in Europe. I will then use ecological modelling to identify those loci whose patterns of selection are associated with ecogeographical variables and hence represent adaptations to local environmental conditions. I will assign dates to the periods when adaptations occurred by sequencing ancient DNA from archaeobotanical assemblages and by computer methods that enable the temporal order of adaptations to be deduced. I will then synthesise the information on environmental adaptations with dating evidence for the spread of agriculture in Europe, which reveals pauses that might be linked to environmental adaptation, with demographic data that indicate regions where Neolithic populations declined, possibly due to inadequate crop productivity, and with an archaeobotanical database showing changes in the prevalence of individual cereals in different regions."

Call Details Advanced Grant (AdG), SH6, ERC-2019-ADG
Summary The historiography of Euro-American abolitionism is so vast that it has a history of its own (Brown 2006). By contrast, research on African abolitionism is a narrow field focused primarily on European anti-slavery activities. It presupposes that when Europe abolished slavery in Africa, Africans became abolitionists. This conclusion is unfounded. Many general questions have never been asked: When and where did African abolitionist movements develop? Who are the main ideologues of African abolitionism? How did abolitionism spread, among which groups? What forms of political struggle did African anti-slavery give rise to? While individual African abolitionists and regional movements have attracted limited attention, there is no major review of the phenomenon on a continental scale. AFRAB fills this gap. It contributes to African and global history and slavery studies by analyzing and comparing African abolitionist ideas and anti-slavery movements, the long-term consequences of European abolitionism, and the resilience of pro-slavery discourses.

Call Details Advanced Grant (AdG), SH6, ERC-2008-AdG
Summary This project focuses on one of the most fascinating events of the long history of the human species: the origins and spread of agriculture. Research over the past 40 years has provided an invaluable dataset on crop domestication and the spread of agriculture into Europe. However, despite the enormous advances in research there are important areas that remain almost unexplored, some of immense interest. This is the case of the western Mediterranean region from where our knowledge is still limited (Iberian Peninsula) or almost inexistent (northern Morocco). The last few years have witnessed a considerable increase in archaeobotany and the effort of a group of Spanish researchers working together in different aspects of agriculture has started to produce the first results. My proposal will approach the study of the arrival of agriculture to the western Mediterranean by exploring different interrelated research areas. The project involves the
application of different techniques (analysis of charred plant remains, pollen and non-pollen microfossils, phytoliths, micro-wear analyses, isotopes, soil micromorphology, genetics, and ethnoarchaeology) which will help to define the emergence and spread of agriculture in the area, its likely place of origin, its main technological attributes as well as the range crop husbandry practices carried out. The interaction between the different approaches and the methodologies involved will allow achieving a greater understanding of the type of agriculture that characterized the first farming communities in the most south-western part of Europe.

Host Institution (HI) AALTO KORKEAKOULUSAATIO SR
Country Finland
Call Details Advanced Grant (AdG), PE8, ERC-2013-ADG
Summary "Electrical motors consume about 40 % of the electrical energy produced in the European Union. About 90 % of this energy is converted to mechanical work. However, 0.5-2.5 % of it goes to so called additional load losses whose exact origins are unknown. Our ambitious aim is to reveal the origins of these losses, build up numerical tools for modeling them and optimize electrical motors to minimize the losses.
As the hypothesis of the research, we assume that the additional losses mainly result from the deterioration of the core materials during the manufacturing process of the machine. By calorimetric measurements, we have found that the core losses of electrical machines may be twice as large as comprehensive loss models predict. The electrical steel sheets are punched, welded together and shrink fit to the frame. This causes residual strains in the core sheets deteriorating their magnetic characteristics. The cutting burrs make galvanic contacts between the sheets and form paths for inter-lamination currents. Another potential source of additional losses are the circulating currents between the parallel strands of random-wound armature windings. The stochastic nature of these potential sources of additional losses puts more challenge on the research.
We shall develop a physical loss model that couples the mechanical strains and electromagnetic losses in electrical steel sheets and apply the new model for comprehensive loss analysis of electrical machines. The stochastic variables related to the core losses and circulating-current losses will be discretized together with the temporal and spatial discretization of the electromechanical field variables. The numerical stochastic loss model will be used to search for such machine constructions that are insensitive to the manufacturing defects. We shall validate the new numerical loss models by electromechanical and calorimetric measurements."

Researcher (PI) Carlos Ibanez
Host Institution (HI) KAROLINSKA INSTITUTET
Country Sweden
Call Details Advanced Grant (AdG), LS4, ERC-2008-AdG
Summary The aim of this proposal is to understand a novel regulatory signaling network controlling insulin secretion, fat accumulation and energy balance centered around selected components of the TGF-² signaling system, including Activins A and B, GDF-3 and their receptors ALK7 and ALK4. Recent results from my laboratory indicate that these molecules are part of paracrine signaling networks that control important functions in pancreatic islets and adipose tissue through feedback inhibition and feed-forward regulation. These discoveries have open up a new research area with important implications for the understanding of metabolic networks and the treatment of human metabolic syndromes, such as diabetes and obesity.
To drive progress in this new research area beyond the state-of-the-art it is proposed to: i) Elucidate the molecular mechanisms by which Activins regulate Ca2+ influx and insulin secretion in pancreatic ²-cells; ii) Elucidate the molecular mechanisms underlying the effects of GDF-3 on adipocyte metabolism, turnover and fat accumulation; iii) Investigate the interplay between insulin levels and fat deposition in the development of insulin resistance using mutant mice lacking Activin B and GDF-3; iv) Investigate tissue-specific contributions of ALK7 and ALK4 signaling to metabolic control by generating and characterizing conditional mutant mice; v) Investigate the effects of specific and reversible inactivation of ALK7 and ALK4 on metabolic regulation using a novel chemical-genetic approach based on analog-sensitive alleles.
This is research of a high-gain/high-risk nature. It is posed to open unique opportunities for further exploration of complex metabolic networks. The development of drugs capable of enhancing insulin secretion, limiting fat accumulation and ameliorating diet-induced obesity by targeting components of the ALK7 signaling network will find a strong rationale in the results of the proposed work.

Summary Compound semiconductor solar cells are providing the highest photovoltaic conversion efficiency, yet their performance lacks far behind the theoretical potential. This is a position we will challenge by engineering advanced III-V optoelectronics materials and heterostructures for better utilization of the solar spectrum, enabling efficiencies approaching practical limits. The work is strongly motivated by the global need for renewable energy sources. To this end, AMETIST framework is based on three vectors of excellence in: i) material science and epitaxial processes, ii) advanced solar cells exploiting nanophotonics concepts, and iii) new device fabrication technologies.
Novel heterostructures (e.g. GaInNAsSb, GaNAsBi), providing absorption in a broad spectral range from 0.7 eV to 1.4 eV, will be synthesized and monolithically integrated in tandem cells with up to 8-junctions. Nanophotonic methods for light-trapping, spectral and spatial control of solar radiation will be developed to further enhance the absorption. To ensure a high long-term impact, the project will validate the use of state-of-the-art molecular-beam-epitaxy processes for fabrication of economically viable ultra-high efficiency solar cells. The ultimate efficiency target is to reach a level of 55%. This would enable to generate renewable/ecological/sustainable energy at a levelized production cost below ~7 ¢/kWh, comparable or cheaper than fossil fuels. The work will also bring a new breath of developments for more efficient space photovoltaic systems.
AMETIST will leverage the leading position of the applicant in topical technology areas relevant for the project (i.e. epitaxy of III-N/Bi-V alloys and key achievements concerning GaInNAsSb-based tandem solar cells). Thus it renders a unique opportunity to capitalize on the group expertize and position Europe at the forefront in the global competition for demonstrating more efficient and economically viable photovoltaic technologies.

Summary How did politics and inequality work in prehistoric Europe? Traditionally, politics has been seen in terms of discrete political ranks identified through differential treatment of individual burials. But this results in classifying much of prehistory, where the dead were treated in ways which effaced individual identity, as egalitarian. The result is an artificially dichotomous history: Neolithic people had landscapes, rituals and ancestors, Bronze and Iron Age people had politics and inequality. In the last two decades this approach has been strongly critiqued. Burial treatment rarely relates to status so directly; the dead serve many different political roles. Inequality in pre-state groups rarely consists of clear strata; inequality and equality exist in tension within groups. Inequality may have been present throughout European prehistory, but manifest situationally through differential life chances, kinship, ritual or ancestorhood, rather than overtly through political command, wealth or identity. But this new perspective has never been tested empirically.
This project tests alternative models of prehistoric inequality and deathways. To investigate social relations in life, it uses osteobiography, reconstructing life stories from skeletons through scientific data on identity, health, diet, mobility and kinship. To understand deathways, it employs a second new methodology, funerary taphonomy. Combining osteobiography and taphonomy allows us to connect ancient lives and deaths. Peninsular Italy provides a substantial test sequence typical of much of Europe. For each of three key periods (Neolithic, 6000-4000 BC; Final Neolithic to Early Bronze Age, 4000-1800 BC; Middle Bronze Age to Iron Age, 1800-600 BC), 200+ individuals will be analysed. The results will allow us to evaluate for the first time how inequality affected lives in prehistoric Europe and what role ancestors played in it.

To investigate social relations in life, it uses osteobiography, reconstructing life stories from skeletons through scientific data on identity, health, diet, mobility and kinship. To understand deathways, it employs a second new methodology, funerary taphonomy. Combining osteobiography and taphonomy allows us to connect ancient lives and deaths. Peninsular Italy provides a substantial test sequence typical of much of Europe. For each of three key periods (Neolithic, 6000-4000 BC; Final Neolithic to Early Bronze Age, 4000-1800 BC; Middle Bronze Age to Iron Age, 1800-600 BC), 200+ individuals will be analysed. The results will allow us to evaluate for the first time how inequality affected lives in prehistoric Europe and what role ancestors played in it.
