: RESOLVE : SuppRESsion of immunopathology by nanOparticle deLiVEry of mRNA to monocytes

The aim of RESOLVE is to pursue the development of innovative nanosystems as novel therapeutic approaches based on the engineering of nanomedicine to limit the immune reactivity against host self-antigens in the course of bone marrow transplantation (graft versus host disease, GvHD) and autoimmune diseases (multiple sclerosis, MS). Currently, therapeutics for these pathologies are based on either systemic or local immunosuppression, which eliminate or suppress polyclonal, autoreactive T-cell specificities while compromising the entire systemic immunity with many side effects, sometimes life threatening. But the most promising strategies to come are represented by either restoration or de novo induction of cells able to induce tolerance, such as the monocytic myeloid-derived suppressor cells (MO-MDSCs). Their immunosuppressive activity, and consequently their tolerogenic ability, can be enhanced by increasing the cellular level of a protein involved in apoptosis regulation, CFLAR. In the course of the present project, new nanosystems will be designed to specifically target in vivo the MO-MDSCs, and efficiently deliver mRNAs to produce CFLAR. The specific expression of the protein, both at the cellular and tissue levels, the in vivo nanosystem biodistribution and the therapeutic efficacy in mouse models of GvHD and MS, will be assessed.

Résumé: The aim of this project is to develop a fundamental understanding of the different phenomena observed during condensed mode cooling in ethylene polymerization, and translate this new knowledge into a sophisticated model able to predict the reactor performance. Accordingly, the project is organized into three subsequent tasks covering the different scales typical of the system, from the single particle to the reactor. Namely, the equilibrium partitioning of different species (monomer, comonomers, solvents, inerts) into polyethylene films and particles will be studied experimentally using different techniques. Then, such thermodynamic knowledge will be incorporated into a single-particle model accounting for the reaction and diffusion phenomena as well as the thermal behavior. Such model will be validated by comparison with experimental data obtained using specially designed spherical stirred bed reactors that are well adapted for gas phase polymerization. Finally, taking advantage of computational efficient methods, a comprehensive model of stirred-bed reactor will be developed, accounting for all phenomena affecting the particle size distribution, such as aggregation due to polymer softening related to the plasticization induced by additional species.

ANR “Design of efficient nanoparticles for skin decontamination towards Chemical Warfare Agents”

Chemical warfare agents (CWA) such as the nerve agent VX (organophosphorous OPCs) and the vesicant sulfur mustard (organochlorines OCCs), have been used recently in conflicts, but also in terrorist acts targeting civilian. Liquids or droplet aerosol forms of CWA can be absorbed through the skin, but also by many other organs such as the eyes, or the respiratory tract if there is no sufficient protection of the body surface. The first signs of percutaneous intoxication appear quickly in the form of severe functional disturbances at respiratory, cardiovascular, muscular, pupilar, digestive levels for OPCs and blistering of the skin followed by deep ulcerations for OCCs. These disturbances can lead at last to death. Body surface decontamination is therefore crucial to prevent victims poisoning. It reduces the amount of contaminant on the skin surface and thus, decreases the penetration rate and the extent of intoxication. Different decontaminant systems are currently available for skin decontamination. Some systems act by adsorption and displacement of the toxic agent such as Fuller’s Earth (FE) and other systems act by neutralization (chemical degradation) such as the Canadian Reactive Skin Decontaminant Lotion (RSDL). However, these procedures do not eliminate the toxic contaminant, which may disqualify them for use in enclosed spaces and in cases where the waste disposal cannot be ensured. Chemical procedures decompose or convert toxic substances to non-toxic or less toxic products. Generally, the reagents are suitable for a specific group of contaminants (a few are universal). Because of the shortcomings of all current decontamination methods advances in technology are necessary to increase the effectiveness of decontamination methods towards several toxic agents. The aim of the project will be to develop a universal product efficient against several CWAs, easy to handle and lost cost. New types of decontamination agents such as nanocrystalline metal oxides have been recently introduced that exhibit adsorption but also an ability to typically degrade hazardous chemicals and CWAs. The application of cerium oxide, the most abundant rare earth, has been rarely mentioned in literature but it is efficient against CWA simulants even if the mechanisms are not elucidated. Nanoparticles with specific habits and controlled granulometric distribution and non-aggregated will be designed by two main methods: Pulse Laser Ablation in Liquids and Solvothermal Synthesis Process. Both methods allow tuning the habits of particles. The main objective of this part is to correlate the physicochemical properties of particles to their degradation efficiency. Then, new materials will be designed and finally formulated. The in vitro efficiency of particles to degrade OPCs and OCCs simulants will be ranked. Finally the decontamination efficiency of the better formulations will be tested on skin explants according to the AFNOR guideline to lead to a prototype and a proof-of-concept.

ANR “Innovative membrane Crystallization contactor: Applications to diffusion/Reaction processes”



Crystallization/Precipitation is one of the major unit operations of chemicals process industries to produce, purify or separate solid compounds or products. Until now, the process reference, i.e. the stirred tank reactor, stays the current crystallization process. But the need for breakthrough technologies has been highlighted by numerous authors and reports. Amongst the commonly reported technologies, membranes are one of the most promising to ensure an intensified continuous process, easy to scale-up but also to grant a fine control of the hydrodynamic and the mass/heat transfers. However, the use of microporous membranes, mainly reported in the literature, have major issues which are pores blocking by crystals, pores wetting by liquid phase and fouling, i.e. the deposit of solid compound in/on the membrane. Whatever the issue, it causes a decrease of the mass/heat transfer through the membrane inducing a decline of the process performances which are reversible or not.
To avoid pores blocking and pores wetting, the use of dense or composites membranes appear as a promising alternative. The dense membrane or the dense skin of the composite membrane has to be as finer as possible and the polymer material has to highly permeable to limit the membrane mass transfer resistance. Nevertheless, fouling stays the main issue and is currently reported on reverse osmosis membranes. In fact, intramembrane crystallization and surface deposits have been observed, depending on the type of system, but no quantitative interpretation is available. Hence, the choice of the polymer material, to a membrane processes, only considers its lower resistance to mass/heat transfer, which stays one of the most important parameter, or its hydrophobicity.
Thus, the ICARE project intends to investigate the local phenomena in order to understand and explain how, why, where and when the crystallization takes place in/on the polymer material. By the quantitative prediction of crystallization location, the aim of the ICARE project is to develop a rational knowledge of the interactions between crystals properties, operating conditions and membrane materials characteristics in order to rethink the choice of the polymer material in crystallization/precipitation membrane processes.
By choosing better the polymer material, the robustness and the life expectancy of the process membrane will be greatly improved.
But more generally, the understanding of the interactions between fluid conditions, crystals properties and membrane characteristics which constitute a breakthrough approach, could also be employed in different other application domains. Hence, in the Energy area, the choice of the polymer material used (heat exchanger or pressured retarded osmosis) reflected the same phenomenology. The same questioning could also be applied to the Water area, on the membrane used in reverse osmosis or ion exchange where fouling is almost systematically encountered. Regarding the Health fields, the benefit is completely different. Indeed, due to the comprehension of the interactions, new system of drug controlled delivery could be considered such as to inject insulin or drugs against cancer or long pain…
The potentialities will be almost unlimited. The last but not the least area which could benefit from the project is the Materials fields. By understanding how, why, where and when the solid formation takes place, in or on a polymer materials, it is possible to plan to do specific materials with the selected properties.

ANR “Polydopamine-coated open cell polyurethane foams: polyvalent supports for single and multi-site heterogeneous catalyst”

Continuous processes based on Structured Catalytic Supports (SCS) are widely used in industry. Indeed this type of support allows an important surface over volume ratio, a small pressure loss, efficient mass transfers, an intimate mixing of the reagents, and an easy separation of the products from the catalyst. Among the variety of SCS, open cell foams are prime candidates, which fulfill all these features. Of ceramic or metallic constitution, these host architectures are ideal supports for metallic particles. The preparation of these foams however requires several steps, and the physisorption of metallic particles a thermic treatment at very high temperature. This expensive and energy consuming way of preparation represents an important drawback in the development of this kind of catalyst, especially when taking into account the current economic and ecological constraints. Moreover these foams present a number of others drawbacks inherent to their structure: (i) they are heavy and thus difficult to handle, (ii) they are not flexible and usually display micro-cracks, which render them breakable, (iii) they present many closed cells, which renders the reproducibility unpredictable, and (iv) the recovery of the expensive catalyst adsorbed on the foam often necessitates numerous chemical treatments in highly corrosive media.
With POLYCATPUF, we propose an alternative based on the use of polyurethane open cell foams (OCPUF). These foams, commercially available in very large quantities and at low cost, present the same structural properties than ceramic or metallic foams, with the advantage to be easily engineered because of their lightweight and mechanical flexibility (elastomer). Recently, we have demonstrated that the whole surface of this polymeric structured material can be efficiently coated with polydopamine (PDA). This layer of PDA (OCPUF@PDA) allows the grafting of inorganic nanoparticles, as well as the covalent anchoring of organic compounds (Patent WO 2016 012689 A2). Moreover this coating process is industrially valuable because it operates at room temperature in water in the sole presence of dopamine and a buffer. These preliminary results constitute the basis of our project.
POLYCATPUF is a frontier research project that involves the close collaboration of three academic partners, mastered in surface science and materials, catalysis, and chemical engineering, and of an industrial partner. A consortium based on an experience of several years between the partners. The project aims to demonstrate all the potentialities offered by open cell polymeric foams as support for both homogeneous and heterogeneous catalysts. First of all, the covalent anchoring of homogeneous catalysts opens the door to a large variety of catalysts that were unconceivable with ceramic or metallic foams. The possibility to graft both single-site and multi-site catalysts allows conceiving processes of combined catalysis. Thanks to the presence of an industrial partner, the use of OCPUF as catalytic support will also be evaluated in an industrial reactor. Finally based on the elastic properties of OCPUF, innovative reactors will be envisioned.
The use of these OCPUF as catalytic supports may thus have a significant scientific, technologic, economic, and ecologic impact on the current industrial processes, from which might benefit the whole society.

    Paul Kotyczka, Ass. Professor at the Technical University of Munich (Germany) spends one year at DYCOP-LAGEP from Sept. 1., 2015 in the frame of MARIE SKLODOWSKA-CURIE ACTIONS Individual Fellowships (IF), EU project 655204- EasyEBC Easy-to-Implement Energy-Based Control Design for Systems of Conservation Laws.

    Summary:. The aim of EasyEBC is to develop easy-to-handle energy-based control design procedures for nonlinear systems of conservation laws in the port-Hamiltonian framework. Linear and nonlinear methods from mathematical control theory of finite- and infinite-dimensional systems will be applied for analysis and control synthesis, e.g. semi-group theory, discretization techniques, and energy shaping. The mathematics will be masked behind a user-friendly frontend that offers transparent tuning criteria for the closed-loop dynamics. Bridging the gap between mathematical complexity and easy applicability of the design tools is the main challenge of the project. As a long-term impact, EasyEBC will contribute to making nonlinear model-based control more accessible to engineers beyond academia.

    LIGNAROCAT: Lignin to aromatics catalytic process

    Type : French National Research Agency (ANR)

    Aims : The main objective of this project is to develop a flexible process adapted to a wide range of lignins with selective catalysts in order to get mainly aromatics in the liquid effluents for a potential industrial valorization. In order to achieve this goal, the hydroconversion of, at least two different types of lignins, one from pulp industry, and one produced during cellulosic ethanol production, will be studied in addition to the wheat straw lignin used previously. The methodology planned for this project includes a study of the lignin solubility, a catalytic screening, the kinetic modeling of the hydroconversion and the evolution of the batch system into a semi-continuous reactor with further improvements, like for instance, solid injection, continuous gas phase and water removal.

    Abstract : Facing the need of energy independance and worldwide environmental concerns, lignocellulosic biomass was identified as one of most powerful carbon resource for biofuels and biochemicals. Lignin which one of the components of lignocellulosic biomass is few valorized at the moment. However lignin is already co-produced in pulp industry and it is the only recognized aromatics renewable source on the earth. In this project, we propose to develop selective lignin catalytic hydroconversion towards aromatic compounds, taking in account our experience in this area. A screening of well-chosen catalysts will be performed in a semi-opened batch reactor and then the technology will be transferred to a continuous process development via conversion kinetic modeling and thermodynamic parameters study.

    Abstract project PICKEP
    The aim of the present project is to develop a methodology for fundamental modeling of surfactant-free emulsion polymerization processes stabilized by inorganic particles, referred to as “Pickering emulsion polymerization (PickEP)”. The model should be able to describe the reaction kinetics in the different phases, mass transfer between phases (ex. radicals) and the evolution of the particle size distribution (PSD), which is an important end-use property of the latex. The sought model will be based on individual fundamental sub-models representing particle nucleation, growth, coagulation, mass transfer, partitioning of inorganic particles and the reaction kinetics in the different phases. Sub-models are autonomous pieces that are individually identified and validated experimentally representing an elementary mechanism. The obtained model will improve process understanding and can be used in control strategies in order to improve the product quality, mainly to increase the solid contents of the latex for industrial interest.
