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.

BioELCell will deliver ground-breaking approaches to create next material generation based on renewable resources, mainly cellulose and lignin micro- and nano-particles (MNC, MNL). Our action will disassemble and re-engineer these plant-based polymers into functional materials that will respond to the demands of the bioeconomy of the future, critically important to Europe and the world. My ambitious, high gain research plan is underpinned in the use of multiphase systems with ultra-low interfacial tension to facilitate nanocellulose liberation and atomization of lignin solution streams into spherical particles. BioELCell will design novel routes to control MNC and MNL reassembly in new 1-D, 2-D and 3-D structures. The systematic methodologies that I propose will address the main challenges for lignocellulose processing and deployment, considering the important effects of interactions with water. This BioELCell action presents a transformative approach by integrating complementary disciplines that will lead to a far-reaching understanding of lignocellulosic biopolymers and solve key challenges in their use, paving the way to functional product development. Results of this project permeates directly or indirectly in the grand challenges for engineering, namely, water use, carbon sequestration, nitrogen cycle, food and advanced materials. Indeed, after addressing the key fundamental elements of the research lines, BioELCell vindicates such effects based on rational use of plant-based materials as a sustainable resource, making possible the generation of new functions and advanced materials. BioELCell goes far beyond what is known today about cellulose and lignin micro and nano-particles, some of the most promising materials of our century, which are emerging as key elements for the success of a sustainable society.

What did politicians sound like before they were on the radio and television? The fascination with politicians’ vocal characteristics and quirks is often connected to the rise of audio-visual media. But in the age of the printed press, political representatives also had to ‘speak well’ – without recourse to amplification. Historians and linguists have provided sophisticated understandings of the discursive and aesthetic aspects of politicians’ language, but have largely ignored the importance of the acoustic character of their speech. CALLIOPE studies how vocal performances in parliament have influenced the course of political careers and political decision making in the 19th century. It shows how politicians’ voices helped to define the diverse identities they articulated. In viewing parliament through the lens of audibility, the project offers a new perspective on political representation by reframing how authority was embodied (through performances that were heard, rather than seen). It does so for the Second Chamber in Britain and France, and in dialogue with ‘colonial’ modes of speech in Kolkata and Algiers, which, we argue, exerted considerable influence on European vocal culture. The project devises an innovative methodological approach to include the sound of the human voice in studies of the past that precede acoustic recording. Adapting methods developed in sound studies and combining them with the tools of political history, the project proposes a new way to analyse parliamentary reporting, while also drawing on a variety of sources that are rarely connected to the history of politics. The main source material for the study comprise transcripts of parliamentary speech (official reports and renditions by journalists). However, the project also mobilizes educational, satirical and fictional sources to elucidate the convoluted processes that led to the cultivation, exertion, reception and evaluation of a voice ‘fit’ for nineteenth-century politics.

Metal organic frameworks (MOFs) are recently considered as new fascinating nanoporous materials. MOFs have very large surface areas, high porosities, various pore sizes/shapes, chemical functionalities and good thermal/chemical stabilities. These properties make MOFs highly promising for gas separation applications. Thousands of MOFs have been synthesized in the last decade. The large number of available MOFs creates excellent opportunities to develop energy-efficient gas separation technologies. On the other hand, it is very challenging to identify the best materials for each gas separation of interest. Considering the continuous rapid increase in the number of synthesized materials, it is practically not possible to test each MOF using purely experimental manners. Highly accurate computational methods are required to identify the most promising MOFs to direct experimental efforts, time and resources to those materials. In this project, I will build a complete MOF library and use molecular simulations to assess adsorption and diffusion properties of gas mixtures in MOFs. Results of simulations will be used to predict adsorbent and membrane properties of MOFs for scientifically and technologically important gas separation processes such as CO2/CH4 (natural gas purification), CO2/N2 (flue gas separation), CO2/H2, CH4/H2 and N2/H2 (hydrogen recovery). I will obtain the fundamental, atomic-level insights into the common features of the top-performing MOFs and establish structure-performance relations. These relations will be used as guidelines to computationally design new MOFs with outstanding separation performances for CO2 capture and H2 recovery. These new MOFs will be finally synthesized in the lab scale and tested as adsorbents and membranes under practical operating conditions for each gas separation of interest. Combining a multi-stage computational approach with experiments, this project will lead to novel, efficient gas separation technologies based on MOFs.
