Summary The field of C-H bond activation has evolved at an exponential pace in the last 15 years. What appeals most in those novel synthetic techniques is clear: they bypass the pre-activation steps usually required in traditional cross-coupling chemistry by directly metalating C-H bonds. Many C-H bond functionalizations today however, rely on poorly atom and step efficient oxidants, leading to significant and costly chemical waste, thereby seriously undermining the overall sustainability of those methods. As restrictions in sustainability regulations will further increase, and the cost of certain chemical commodities will rise, atom efficiency in organic synthesis remains a top priority for research.
The aim of 2O2ACTIVATION is to develop novel technologies utilizing O2 as sole terminal oxidant in order to allow useful, extremely sustainable, thermodynamically challenging, dehydrogenative C-N and C-O bond forming coupling reactions. However, the moderate reactivity of O2 towards many catalysts constitutes a major challenge. 2O2ACTIVATION will pioneer the design of new catalysts based on the ultra-simple propene motive, capable of direct activation of O2 for C-H activation based cross-couplings. The project is divided into 3 major lines: O2 activation using propene and its analogues (propenoids), 1) without metal or halide, 2) with hypervalent halide catalysis, 3) with metal catalyzed C-H activation.
The philosophy of 2O2ACTIVATION is to focus C-H functionalization method development on the oxidative event.
Consequently, 2O2ACTIVATION breakthroughs will dramatically shortcut synthetic routes through the use of inactivated, unprotected, and readily available building blocks; and thus should be easily scalable. This will lead to a strong decrease in the costs related to the production of many essential chemicals, while preserving the environment (water as terminal by-product). The resulting novels coupling methods will thus have a lasting impact on the chemical industry.

Summary The clinical success of anticancer and antiviral vaccines often requires the use of an adjuvant, a substance that helps stimulate the body’s immune response to the vaccine, making it work better. However, few adjuvants are sufficiently potent and non-toxic for clinical use; moreover, it is not really known how they work. Current vaccine approaches based on weak carbohydrate and glycopeptide antigens are not being particularly effective to induce the human immune system to mount an effective fight against cancer. Despite intensive research and several clinical trials, no such carbohydrate-based antitumor vaccine has yet been approved for public use. In this context, the proposed project has a double, ultimate goal based on applying chemistry to address the above clear gaps in the adjuvant-vaccine field. First, I will develop new improved adjuvants and novel chemical strategies towards more effective, self-adjuvanting synthetic vaccines. Second, I will probe deeply into the molecular mechanisms of the synthetic constructs by combining extensive immunological evaluations with molecular target identification and detailed conformational studies. Thus, the singularity of this multidisciplinary proposal stems from the integration of its main objectives and approaches connecting chemical synthesis and chemical/structural biology with cellular and molecular immunology. This ground-breaking project at the chemistry-biology frontier will allow me to establish my own independent research group and explore key unresolved mechanistic questions in the adjuvant/vaccine arena with extraordinary chemical precision. Therefore, with this transformative and timely research program I aim to (a) develop novel synthetic antitumor and antiviral vaccines with improved properties and efficacy for their prospective translation into the clinic and (b) gain new critical insights into the molecular basis and three-dimensional structure underlying the biological activity of these constructs.

Project Bond activation and catalysis with low-valent aluminium
Researcher (PI) Michael James COWLEY
Host Institution (HI) THE UNIVERSITY OF EDINBURGH
Call Details Starting Grant (StG), PE5, ERC-2016-STG
Summary This project will develop the principles required to enable bond-modifying redox catalysis based on aluminium by preparing and studying new Al(I) compounds capable of reversible oxidative addition.
Catalytic processes are involved in the synthesis of 75 % of all industrially produced chemicals, but most catalysts involved are based on precious metals such as rhodium, palladium or platinum. These metals are expensive and their supply limited and unstable; there is a significant need to develop the chemistry of non-precious metals as alternatives. On toxicity and abundance alone, aluminium is an attractive candidate. Furthermore, recent work, including in our group, has demonstrated that Al(I) compounds can perform a key step in catalytic cycles - the oxidative addition of E-H bonds.
In order to realise the significant potential of Al(I) for transition-metal style catalysis we urgently need to:
- establish the principles governing oxidative addition and reductive elimination reactivity in aluminium systems.
- know how the reactivity of Al(I) compounds can be controlled by varying properties of ligand frameworks.
- understand the onward reactivity of oxidative addition products of Al(I) to enable applications in catalysis.
In this project we will:
- Study mechanisms of oxidative addition and reductive elimination of a range of synthetically relevant bonds at Al(I) centres, establishing the principles governing this fundamental reactivity.
- Develop new ligand frameworks to support of Al(I) centres and evaluate the effect of the ligand on oxidative addition/reductive elimination at Al centres.
- Investigate methods for Al-mediated functionalisation of organic compounds by exploring the reactivity of E-H oxidative addition products with unsaturated organic compounds.

Project Analysing South-South Humanitarian Responses to Displacement from Syria: Views from Lebanon, Jordan and Turkey
Researcher (PI) Elena FIDDIAN-QASMIYEH
Host Institution (HI) UNIVERSITY COLLEGE LONDON
Call Details Starting Grant (StG), SH3, ERC-2016-STG
Summary Since 2012, over 4 million people have fled Syria in ‘the most dramatic humanitarian crisis that we have ever faced’ (UNHCR). By November 2015 there were 1,078,338 refugees from Syria in Lebanon, 630,776 in Jordan and 2,181,293 in Turkey. Humanitarian agencies and donor states from both the global North and the global South have funded and implemented aid programmes, and yet commentators have argued that civil society groups from the global South are the most significant actors supporting refugees in Lebanon, Jordan and Turkey. Whilst they are highly significant responses, however, major gaps in knowledge remain regarding the motivations, nature and implications of Southern-led responses to conflict-induced displacement. This project draws on multi-sited ethnographic and participatory research with refugees from Syria and their aid providers in Lebanon, Jordan and Turkey to critically examine why, how and with what effect actors from the South have responded to the displacement of refugees from Syria. The main research aims are:
1. identifying diverse models of Southern-led responses to conflict-induced displacement,
2. examining the (un)official motivations, nature and implications of Southern-led responses,
3. examining refugees’ experiences and perceptions of Southern-led responses,
4. exploring diverse Southern and Northern actors’ perceptions of Southern-led responses,
5. tracing the implications of Southern-led initiatives for humanitarian theory and practice.
Based on a critical theoretical framework inspired by post-colonial and feminist approaches, the project contributes to theories of humanitarianism and debates regarding donor-recipient relations and refugees’ agency in displacement situations. It will also inform the development of policies to most appropriately address refugees’ needs and rights. This highly topical and innovative project thus has far-reaching implications for refugees and local communities, academics, policy-makers and practitioners.

Project Atomic Scale Defects: Structure and Function
Researcher (PI) Felix HOFMANN
Host Institution (HI) THE CHANCELLOR, MASTERS AND SCHOLARS OF THE UNIVERSITY OF OXFORD
Call Details Starting Grant (StG), PE5, ERC-2016-STG
Summary Atomic scale defects play a key role in determining the behaviour of all crystalline materials, profoundly modifying mechanical, thermal and electrical properties. Many current technological applications make do with phenomenological descriptions of these effects; yet myriad intriguing questions about the fundamental link between defect structure and material function remain.
Transmission electron microscopy revolutionised the study of atomic scale defects by enabling their direct imaging. The novel coherent X-ray diffraction techniques developed in this project promise a similar advancement, making it possible to probe the strain fields that govern defect interactions in 3D with high spatial resolution (<10 nm). They will allow us to clarify the effect of impurities and retained gas on dislocation strain fields, shedding light on opportunities to engineer dislocation properties. The exceptional strain sensitivity of coherent diffraction will enable us to explore the fundamental mechanisms governing the behaviour of ion-implantation-induced point defects that are invisible to TEM. While we concentrate on dislocations and point defects, the new techniques will apply to all crystalline materials where defects are important. Our characterisation of defect structure will be combined with laser transient grating measurements of thermal transport changes due to specific defect populations. This unique multifaceted perspective of defect behaviour will transform our ability to devise modelling approaches linking defect structure to material function.
Our proof-of-concept results highlight the feasibility of this ambitious research project. It opens up a vast range of exciting possibilities to gain a deep, fundamental understanding of atomic scale defects and their effect on material function. This is an essential prerequisite for exploiting and engineering defects to enhance material properties.

Host Institution (HI) UNIVERSITEIT UTRECHT
Call Details Starting Grant (StG), PE5, ERC-2016-STG
Summary Homogeneous catalysis is of prime importance for the selective synthesis of high added value chemicals. Many of the currently available catalysts rely on noble metals (Ru, Os, Rh, Ir, Pd, Pt), which suffer from a high toxicity and environmental impact in addition to their high cost, calling for the development of new systems based on first-row transition metals (Mn, Fe, Co, Ni, Cu). The historical paradigm for catalyst design, i.e. one or more donor ligands giving electron density to stabilize a metal center and tune its reactivity, is currently being challenged by the development of acceptor ligands that mostly withdraw electron density from the metal center upon binding. In the last decade, such ligands – mostly based on boron and heavier main-group elements – have evolved from a structural curiosity to a powerful tool in designing new reactive units for homogeneous catalysis.
I will develop a novel class of ligands that use C=E (E=O, S, NR) multiple bonds anchored in close proximity to the metal by phosphine tethers. The electrophilic C=E multiple bond is designed to act as an acceptor moiety that adapts its binding mode to the electronic structure of reactive intermediates with the unique additional possibility of involving the lone pairs on heteroelement E in cooperative reactivity. Building on preliminary results showing that a C=O bond can function as a hemilabile ligand in a catalytic cycle, I will undertake a systematic, experimental and theoretical investigation of the structure and reactivity of M–C–E three membered rings formed by side-on coordination of C=E bonds to a first-row metal. Their ability to facilitate multi-electron transformations (oxidative addition, atom/group transfer reactions) will be investigated. In particular, hemilability of the C=E bond is expected to facilitate challenging C–C bond forming reactions mediated by Fe and Ni. This approach will demonstrate a new conceptual tool for the design of efficient base-metal catalysts.

Summary Cancer screening and the diagnostics industry: a comparative analysis of the political economy of diagnostic innovation
A decade after the Human Genome Project, major public and private investments continue to fuel expectations of a genomic revolution in biomedicine. The freight of expectations surrounding the new “age of diagnostics” is accompanied by much uncertainty about how public policy should steer diagnostic innovation, with much debate about inter alia the harms of creating diagnostic monopolies through gene patenting, and the risks of under- or over-regulation. However, due to the paucity of research on diagnostic innovation, policy deliberation is driven more by anecdote and expert opinion than empirical evidence. With a specific focus on screening/early detection of cancer, this project will map industry dynamics, technological trajectories and regulatory developments in Europe and the USA from 1996 to the present day. Combining quantitative and qualitative methods, the project’s innovative dimensions include a new conceptual model of socio-technical transition in the diagnostics sector, and the first integrative analysis linking scientometric data on the interactions between public and private actors in the diagnostic research domain with comparative transnational analysis of regulatory decision-making. Through a novel integration of conceptual insights from the literature on biomedicalisation and scholarship on socio-technical regime change, this project aims to advance both fields of research by applying a new multi-scale, multi-level model of socio-technical transition. The project will provide unprecedented insight into the factors shaping the development of a new generation of molecular diagnostic tests, and examine how these technologies are reconfiguring disease categories and redrawing the boundaries between health and sickness. We will establish a platform of theory and methods for a broader programme of work on diagnostic innovation.

Host Institution (HI) UNIVERSITAT DE VALENCIA

Summary 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.

Project The chemical understanding of biomolecular recognition in epigenetics

Host Institution (HI) SYDDANSK UNIVERSITET
Call Details Starting Grant (StG), PE5, ERC-2016-STG
Summary The ultimate aim of this ERC project is to provide a comprehensive and complete understanding, at the atomic-level of sophistication, of genuinely important biomolecular recognition processes in epigenetics that play key roles in human health and disease. At the biochemical level, epigenetics refers to mechanisms, such as enzymatic modifications of DNA and posttranslational modifications of the associated histone proteins, that regulate the activity of human genes. The proposed work aims to address epigenetics using the physical-organic chemistry approach that enables the elucidation of the elemental processes with unprecedented molecular/atomic detail. The project will experimentally and computationally examine non-covalent interactions between three essential constituents of the epigenetic biomolecular system, namely epigenetic proteins, histones and water, at the level of short histone peptides, intact histone proteins, the nucleosome assembly and nucleosome arrays. Our programme, built on synergistic thermodynamic, structural and computational studies, aims to unravel i) the underlying chemical origin of methyllysine-containing histones in epigenetics, ii) the chemical basis for the recognition of methylarginine-containing histones in epigenetic processes, and iii) the role of unstructured histone tails in biomolecular recognition, which together form the three main structural elements found in the epigenetic framework. Results from this work will be important from both a fundamental molecular perspective as well as from the biomedical perspective, because proteins involved in epigenetic regulation processes are currently regarded as important targets for numerous therapeutic interventions, most notably for cancer treatment.

Project The impact of flight experiences on the psychological wellbeing of unaccompanied refugee minors
Researcher (PI) Ilse DERLUYN
Host Institution (HI) UNIVERSITEIT GENT
Call Details Starting Grant (StG), SH3, ERC-2016-STG
Summary Since early 2015, the media continuously confront us with images of refugee children drowning in the Mediterranean, surviving in appalling conditions in camps or walking across Europe. Within this group of fleeing children, a considerable number is travelling without parents, the unaccompanied refugee minors.
While the media images testify to these flight experiences and their possible huge impact on unaccompanied minors’ wellbeing, there has been no systematic research to fully capture these experiences, nor their mental health impact. Equally, no evidence exists on whether the emotional impact of these flight experiences should be differentiated from the impact of the traumatic events these minors endured in their home country or from the daily stressors in the country of settlement.
This project aims to fundamentally increase our knowledge of the impact of experiences during the flight in relation to past trauma and current stressors. To achieve this aim, it is essential to set up a longitudinal follow-up of a large group of unaccompanied refugee minors, whereby our study starts from different transit countries, crosses several European countries, and uses innovative methodological and mixed-methods approaches. I will hereby not only document the psychological impact these flight experiences may have, but also the way in which care and reception structures for unaccompanied minors in both transit and settlement countries can contribute to reducing this mental health impact.
This proposal will fundamentally change the field of migration studies, by introducing a whole new area of study and novel methodological approaches to study these themes. Moreover, other fields, such as trauma studies, will be directly informed by the project, as also clinical, educational and social work interventions for victims of multiple trauma. Last, the findings on the impact of reception and care structures will be highly informative for policy makers and practitioners.
Summary
Since early 2015, the media continuously confront us with images of refugee children drowning in the Mediterranean, surviving in appalling conditions in camps or walking across Europe. Within this group of fleeing children, a considerable number is travelling without parents, the unaccompanied refugee minors.
While the media images testify to these flight experiences and their possible huge impact on unaccompanied minors’ wellbeing, there has been no systematic research to fully capture these experiences, nor their mental health impact. Equally, no evidence exists on whether the emotional impact of these flight experiences should be differentiated from the impact of the traumatic events these minors endured in their home country or from the daily stressors in the country of settlement.
This project aims to fundamentally increase our knowledge of the impact of experiences during the flight in relation to past trauma and current stressors. To achieve this aim, it is essential to set up a longitudinal follow-up of a large group of unaccompanied refugee minors, whereby our study starts from different transit countries, crosses several European countries, and uses innovative methodological and mixed-methods approaches. I will hereby not only document the psychological impact these flight experiences may have, but also the way in which care and reception structures for unaccompanied minors in both transit and settlement countries can contribute to reducing this mental health impact.
This proposal will fundamentally change the field of migration studies, by introducing a whole new area of study and novel methodological approaches to study these themes. Moreover, other fields, such as trauma studies, will be directly informed by the project, as also clinical, educational and social work interventions for victims of multiple trauma. Last, the findings on the impact of reception and care structures will be highly informative for policy makers and practitioners.
