Space exploration is one of boldest and most exciting endeavors that humanity has undertaken, and it holds enormous promise for the future. Our next challenges for the spatial conquest include bringing back samples to Earth by means of robotic missions and continuing the manned exploration program, which aims at sending human beings to Mars and bring them home safely. Inaccurate prediction of the heat-flux to the surface of the spacecraft heat shield can be fatal for the crew or the success of a robotic mission. This quantity is estimated during the design phase. An accurate prediction is a particularly complex task, regarding modelling of the following phenomena that are potential “mission killers:” 1) Radiation of the plasma in the shock layer, 2) Complex surface chemistry on the thermal protection material, 3) Flow transition from laminar to turbulent. Our poor understanding of the coupled mechanisms of radiation, ablation, and transition leads to the difficulties in flux prediction. To avoid failure and ensure safety of the astronauts and payload, engineers resort to “safety factors” to determine the thickness of the heat shield, at the expense of the mass of embarked payload. Thinking out of the box and basic research are thus necessary for advancements of the models that will better define the environment and requirements for the design and safe operation of tomorrow’s space vehicles and planetary probes for the manned space exploration. The three basic ingredients for predictive science are: 1) Physico-chemical models, 2) Computational methods, 3) Experimental data. We propose to follow a complementary approach for prediction. The proposed research aims at: “Integrating new advanced physico-chemical models and computational methods, based on a multidisciplinary approach developed together with physicists, chemists, and applied mathematicians, to create a top-notch multiphysics and multiscale numerical platform for simulations of planetary atmosphere entries, crucial to the new challenges of the manned space exploration program. Experimental data will also be used for validation, following state-of-the-art uncertainty quantification methods.”

"Tissue engineering (TE), the interdisciplinary field combining biomedical and engineering sciences in the search for functional man-made organ replacements, has key issues with the quantity and quality of the generated products. Protocols followed in the lab are mainly trial and error based, requiring a huge amount of manual interventions and lacking clear early time-point quality criteria to guide the process. As a result, these processes are very hard to scale up to industrial production levels. BRIDGE aims to fortify the engineering aspects of the TE field by adding a higher level of understanding and control to the manufacturing process (MP) through the use of in silico models. BRIDGE will focus on the bone TE field to provide proof of concept for its in silico approach. The combination of the applicant's well-received published and ongoing work on a wide range of modelling tools in the bone field combined with the state-of-the-art experimental techniques present in the TE lab of the additional participant allows envisaging following innovation and impact: 1. proof-of-concept of the use of an in silico blue-print for the design and control of a robust modular TE MP; 2. model-derived optimised culture conditions for patient derived cell populations increasing modular robustness of in vitro chondrogenesis/endochondral ossification; 3. in silico identification of a limited set of in vitro biomarkers that is predictive of the in vivo outcome; 4. model-derived optimised culture conditions increasing quantity and quality of the in vivo outcome of the TE MP; 5. incorporation of congenital defects in the in silico MP design, constituting a further validation of BRIDGE’s in silico approach and a necessary step towards personalised medical care. We believe that the systematic – and unprecedented – integration of (bone) TE and mathematical modelling, as proposed in BRIDGE, is required to come to a rationalized, engineering approach to design and control bone TE MPs."

A wide variety of materials including coatings and adhesives, emerging materials for nanotechnology products, as well as everyday food products are processed or delivered as suspensions. The flow properties of such suspensions must be finely adjusted according to the demands of the respective processing techniques, even for the feel of cosmetics and the perception of food products is highly influenced by their rheological properties. The recently developed capillary suspensions concept has the potential to revolutionize product formulations and material design. When a small amount (less than 1%) of a second immiscible liquid is added to the continuous phase of a suspension, the rheological properties of the mixture are dramatically altered from a fluid-like to a gel-like state or from a weak to a strong gel and the strength can be tuned in a wide range covering orders of magnitude. Capillary suspensions can be used to create smart, tunable fluids, stabilize mixtures that would otherwise phase separate, significantly reduce the amount organic or polymeric additives, and the strong particle network can be used as a precursor for the manufacturing of cost-efficient porous ceramics and foams with unprecedented properties. This project will investigate the influence of factors determining capillary suspension formation, the strength of these admixtures as a function of these aspects, and how capillary suspensions depend on external forces. Only such a fundamental understanding of the network formation in capillary suspensions on both the micro- and macroscopic scale will allow for the design of sophisticated new materials. The main objectives of this proposal are to quantify and predict the strength of these admixtures and then use this information to design a variety of new materials in very different application areas including, e.g., porous materials, water-based coatings, ultra low fat foods, and conductive films.

CONTEXT - Nanoporous structures are used for application in catalysis, molecular separation, fuel cells, dye sensitized solar cells etc. Given the near molecular size of the porous network, it is extremely challenging to modify the interior surface of the pores after the nanoporous material has been synthesized. THIS PROPOSAL - Atomic Layer Deposition (ALD) is envisioned as a novel technique for creating catalytically active sites and for controlling the pore size distribution in nanoporous materials. ALD is a self-limited growth method that is characterized by alternating exposure of the growing film to precursor vapours, resulting in the sequential deposition of (sub)monolayers. It provides atomic level control of thickness and composition, and is currently used in micro-electronics to grow films into structures with aspect ratios of up to 100 / 1. We aim to make the fundamental breakthroughs necessary to enable atomic layer deposition to engineer the composition, size and shape of the interior surface of nanoporous materials with aspect ratios in excess of 10,000 / 1. POTENTIAL IMPACT Achieving these objectives will enable atomic level engineering of the interior surface of any porous material. We plan to focus on three specific applications where our results will have both medium and long term impacts: - Engineering the composition of pore walls using ALD, e.g. to create catalytic sites (e.g. Al for acid sites, Ti for redox sites, or Pt, Pd or Ni) - chemical functionalization of the pore walls with atomic level control can result in breakthrough applications in the fields of catalysis and sensors. - Atomic level control of the size of nanopores through ALD controlling the pore size distribution of molecular sieves can potentially lead to breakthrough applications in molecular separation and filtration. - Nanocasting replication of a mesoporous template by means of ALD can result in the mass-scale production of nanotubes.

The project seeks to study the role of digital media in the shaping of transnational memories on disappearance. It investigates a novel case that is in process of shaping: the disappearance of 43 students in Mexico in September 2014. The role of the new media in getting citizens’ attention and in marking a “turning point” was crucial to the upsurge of a counter-movement against the Mexican government and qualifies the event as significant for the transnational arena. The groundbreaking aspect of the project consists in proposing a double approach: a) a theoretical approach in which “disappearance” is considered as a particular crime that becomes a model for analyzing digital memory. Disappearance is a technology that produces a subject with a new ontological status: the disappeared are non-beings, because they are neither alive nor dead. This ontological status transgresses the clear boundaries separating life and death, past, present and future, materiality and immateriality, personal and collective spheres. “Digital memory”, i.e. a memory mediated by digital technology, is also determined by the transgression of the boundaries of given categories b) a multidisciplinary approach situating Mexico´s case in a long transnational history of disappearance in the Hispanic World, including Argentina and Spain. This longer history seeks to compare disappearance as a mnemonic object developed in the global sphere –in social network sites as blogs, Facebook, Twitter and YouTube– in Mexico and the social performances and artistic representations –literature, photo exhibitions, and films– developed in Spain and Argentina. The Mexican case represents a paradigm for the redefinition of the relationship between media and memory. The main output of the project will consist in constructing a theoretical model for analyzing digital mnemonic objects in the rise of networked social movements with a transnational scope.

Not only does the writer’s hand hold the pen, it manipulates pictures as well. Writers touch, hoard, cut, copy, pin and paste various kinds of pictures and these actions integrate literature in visual culture in many ways that have never been tackled as a whole before. Some writers spent their life surrounded by pictures taken from magazines, creating an inspirational environment; yet others nurtured their imagination with touristic leaflets and visual advertisements; others created fictional characters based on collected portraits. What do writers do with pictures? How does literature stage the pictures handled? From very concrete and banal uses of pictures will emerge a new vision of literature as intermediality in action. This investigation applies the tool set of visual anthropology and visual studies to writers for a deeper understanding of visual ecosystems. Covering a large period, from the beginning of mass reproduction in the 1880s and the digital practices of today, HANDLING focuses on the French and French-speaking field and stands as a laboratory to refashion a broader model for relationships between image and text. Its main challenge is to get to the root of contemporary iconographic practices. HANDLING is unconventional because literary studies usually focus on the text: contrary to the norm, it sets the image at the very centre of the literary act. This approach might yield promising results for the visibility of literature in the future, especially in exhibitions. Making these practices visible will make literature itself more visible. As an internationally recognized specialist of text-image relationships with an in-depth knowledge of French/Belgian literature and photography, I will build a team and lead this 5-year ambitious project. Grounded in interdisciplinarity, it will show the significant and unexpected role of literature in material visual culture.

Mimesis is one of the most influential concepts in Western thought. Originally invoked to define humans as the “most imitative” creatures in classical antiquity, mimesis (imitation) has recently been at the centre of theoretical debates in the humanities, social sciences, and the neurosciences concerning the role of “mimicry,” “identification,” “contagion,” and “mirror neurons” in the formation of subjectivity. And yet, despite the growing confirmations that imitation is constitutive of human behaviour, mimesis still tends to be confined to the sphere of realistic representation. The HOM project combines approaches that are usually split in different areas of disciplinary specialization to provide a correction to this tendency. Conceived as a trilogy situated at the crossroads between literary criticism, cinema studies, and critical theory, HOM’s outcomes will result in two monographs and accompanying articles that explore the aesthetic, affective, and conceptual implications of the mimetic faculty. The first, radically reframes a major proponent of anti-mimetic aesthetics in modern literature, Oscar Wilde, by looking back to the classical foundations of theatrical mimesis that inform his corpus; the second considers the material effects of virtual simulation by looking ahead to new digital media via contemporary science-fiction films; and the third establishes an interdisciplinary dialogue between philosophical accounts of mimesis and recent discoveries in the neurosciences. Together, these new perspectives on homo mimeticus reconsider the aesthetic foundations of a major literary author, open up a new line of inquiry in film studies, and steer philosophical debates on mimesis in new interdisciplinary directions.

Multi-materials, combining various materials with different functionalities, are increasingly desired in engineering applications. Reliable material assembly is a great challenge in the development of innovative technologies. The interdiffusion microstructures formed at material interfaces are critical for the performance of the product. However, as more and more elements are involved, their complexity increases and their variety becomes immense. Furthermore, interdiffusion microstructures evolve during processing and in use of the device. Experimental testing of the long-term evolution in assembled devices is extremely time-consuming. The current level of materials models and simulation techniques does not allow in silico (or computer aided) design of multi-component material assemblies, since the parameter space is much too large. With this project, I aim a break-through in computational materials science, using tensor decomposition techniques emerging in data-analysis to guide efficiently high-throughput interdiffusion microstructure simulation studies. The measurable outcomes aimed at, are 1) a high-performance computing software that allows to compute the effect of a huge number of material and process parameters, sufficiently large for reliable in-silico design of multi-materials, on the interdiffusion microstructure evolution, based on a tractable number of simulations, and 2) decomposed tensor descriptions for important multi-material systems enabling reliable computation of interdiffusion microstructure characteristics using a single computer. If successful, the outcomes of this project will allow to significantly accelerate the design of innovative multi-materials. My expertise in microstructure simulations and multi-component materials, and access to collaborations with the top experts in tensor decomposition techniques and materials characterization are crucial to reach this ambitious aim.

The broad aim of this research program is to understand how markets get created, how they evolve, and how specific market organizations affect economic outcomes. It combines theoretical and empirical analyses of specific markets and includes the development of new methods to map theory to data and vice versa. Each market provides a concrete ground to explore the broad questions the project addresses and motivates a distinct set of questions. The first class of markets the research will consider are financial markets. These can be viewed as the archetype of large markets where prices play the main role in the allocation. The focus there will on market creation, market evolution and the process of competition. The second class of markets the research will consider are allocation mechanisms where prices do not play a role in the allocation, making efficiency hard to obtain. The focus there will be on strategic manipulation of preferences by participants, their consequences on outcomes and possible remedies. Together, these markets will contribute to our understanding of how market rules affect outcomes and performance, to what extent laissez-faire evolution fosters efficient market organizations, and when and how public intervention can help generate better market organizations.
