Abstract:
CO2-HyBrid focuses on the validation of CCS technologies in large CO2 emitting industries. This will allow a 20% more efficient CO2 capture process compared to state-of-the-art capture technologies. The main objective of CO2-HyBrid is the validation of a hybrid solution based on a pre-concentration step using membrane processes and a capture stage by chemical absorption. Two types of membrane and two solvents will be used to produce 2 hybrid configurations to be tested in two pilot plants with different characteristics of industrial flue gases (coal / natural gas plant and waste-based pilot plants). The CO2-HyBrid project aims to raise the level of membrane technologies and the hybrid solution to TRL 6. Through this synergy, the benefits of both technologies will be exploited and will result in CO2 elimination costs of 15-25 EUR / ton for many industrial processes. It is also intended to demonstrate the reliability and flexibility of the solution in order to obtain a high purity of carbon dioxide to be used in various industries but also stored in saline aquifers.

Abstract:
Methanation of CO2 is receiving a revived scientific and technological interest: chemical storage of renewable energy as CH4 (Power-to-Gas concept), combined with the use of CO2 (CO2 capture and utilization) bring both an energetic and an environmental advantage. Highly efficient CO2 methanation catalysts, with good CH4 selectivity should have catalytic functionalities ensuring both CO2 and H2 activation. In this context, metal-organic frameworks (MOFs), – a class of extended coordination networks obtained by assembling metal centers to organic linkers – could ensure enhanced dispersion of active metals inside their ordered porous structure, while their gas sorption and storage capacity could be beneficial in respect to CO2 activation.
The main objective of the project is the development of ordered mesoporous MOF-based and MOF-derived Ni catalysts with enhanced catalytic and operational performance in the methanation of CO2. Two strategies are pursued: (a) nucleation of MOF crystals on preshaped solid macrostructures (MOF-based catalysts), and (b) sacrificial use by thermolysis of MOFs to form MOF-derived structures, which inherit the characteristics and properties of the original MOF (high surface area, ordered porous structure, uniform distribution of constituent elements). Thus, after Ni nanoparticle incorporation, ordered mesoporous catalysts could be obtained, with enhanced mass transfer (better accessibility of active sites) and heat integration (better conductive heat transfer) in the catalytic bed. MOF-based and MOF-derived ordered mesoporous Ni catalysts will be structurally, morphologically and functionally characterized, while catalytic tests will pursue the evaluation of catalytic performance under differential and integral conditions, at different temperatures, CO2:H2 ratios, or flow conditions. Stability tests will allow the evaluation of the catalysts life time, while deactivation possibilities might be investigated and regeneration methods proposed.

Abstract:
Metal-organic frameworks (MOFs) are highly versatile compounds due to their exceptionally high surface area and tunable porous structure, as well as their structural diversity. The catalytic applications of MOFs are of great interest from both scientific and technological point of view due to the diversity of catalytic functionalities which can be introduced in precise locations during synthesis or post synthetically. Methanation of CO2 by H2, is an important process due to (a) the environmental benefit, and (b) the energetic/commercial one, and an example of a catalytic application for MOFs. The confined space of MOFs may play the role of a nanoreactor in case of CO2 methanation due to the possibility (a) to activate CO2 inside the pores, and (b) to introduce metal nanoparticles inside the pores which can activate the necessary H2, while the reaction may proceed between these activated species inside the pores. However, the powder form of MOFs does not make them eligible for final applications. Therefore, the present project proposal aims at making a step further in respect to the catalytic applications of MOFs in the CO2 methanation process: from nanoreactor to an intensified packed bed reactor. This intensified packed bed reactor may be obtained by shaping of MOFs through immobilization on various structures, with important advantages: (a) diffusion limitations may be avoided inside the packed bed, (b) pressure drop along the packed bed can be minimized; (c) catalyst attrition and leaching is limited under operation (recovery and reuse); (d) the catalytic active material can be used more effectively; (e) mechanical stability may be enhanced. The main objective of the present project proposal is to shape MOF compounds by macrostructural templating on porous alumina pellets in order to obtain mechanically stable hierarchical porous catalysts (MNP@MOF/Al2O3) for the efficient methanation of CO2 in a high performance experimental fixed bed catalytic reactor.

Abstract:
Biogas is one of the most important renewable biofuels produced at large scales from a wide range of biological wastes. It consists in a mixture of multiple gases with CH4 and CO2 as main components in different ratios depending on the starting raw materials and conditions used for its production. The biogas is not used to generate fuels (methanol or superior liquid fuels), although contains the necessary constituents, mainly due to the low economic efficiency of the reformation process. The main objective of the present proposal is to develop a laboratory scale validated method to transform simulated biogas in synthesis gas with appropriate composition for methanol and liquid fuels synthesis (with H2:CO ratio 2:1) using new bimodal Ni based catalysts. The research will combine: (a) combined steam and dry reforming of methane process, (b) CH4:CO2 ratio from the real biogas and (c) Ni based bimodal catalysts, to give a reliable, laboratory scale validated method to produce syngas from biogas. Silica and alumina based bimodal catalysts promoted with a second oxide (MgO, CaO, ZrO2, CeO2, La2O3) will be prepared and characterized by several methods (BET, XRD, TEM-SEM, temperature programed processes, in-situ DRIFT). The bimodal pore structure is expected to improve the catalytic process because large pores provide rapid access of the reagents to active sites and the small pores provide higher surface area, while the second oxide is expected to contribute to a better metal dispersion and better metal-support interaction. NH3-TPD, CO2-TPD, in-situ DRIFT measurements will give information about the catalytic process related to catalyst structure. Catalytic tests will be developed to establish the optimum catalyst and reaction conditions to make the reformation process more energetic efficient. The catalyst deactivation will be studied in terms of carbon deposition and metal nanoparticles sinterization.

Abstract:
The growing need for energy requires development of new energy sources/carriers and more efficient utilization of energy. Hydrogen is the ideal energy carrier due to its natural abundance and non-polluting nature.
The development of hydrogen storage technologies for mobile applications still requires overcoming some technical barriers.
Different hydrogen storage paths have been envisaged: from the classical storage technologies, namely pressurization and cryogenic liquefaction, to the solid phase storage in metal hydrides, or physisorbed on a solid surface (metal-organic frameworks, covalent organic frameworks) and the organic liquid hydrogen carrier (LC) under ambient conditions.
Chemical hydrogen storage can became competitive if the storage material fulfils some requierements: high gravimetric and volumetric hydrogen content under ambient conditions, energy-efficient reversible charge and discharge, the absence of byproducts, long-term stability, low toxicity, easily available at a large scale and at a low price. The challenge is to find suitable organic carriers.
Formic acid is a promising candidate for reversible hydrogen storage. The aim of this project is to study formic acid decomposition/formation using a new type of catalysts: metallic nanoparticles confined in metal-organic frameworks, to exploit the nanoparticles confinement and the nanoscale properties for reactions of formic acid dehydrogenation and carbon dioxide reduction under mild conditions.

Abstract:
In modern dentistry, both the early prevention of tooth decay and the development of new and efficient restorative materials are generally targeted. Although tremendous efforts have been made in promoting oral hygiene and fluoridation, the prevention of early caries lesions are still challenges for dental research and public health. Recent studies have indicated that nanotechnology might provide novel strategies in dentistry.
Graphene consists in a one-atom-thick planar sheet of sp2–bonded carbon atoms arranged in a hexagonal lattice. Graphene is considered to be the “thinnest and strongest material in the universe” and therefore it has remarkable physical and chemical properties, including superior Young’s modulus (1 TPa) and tensile strength (130 GPa). Recent studies have shown that graphene can be used as nanofiller and can dramatically improve the properties of polymer-based composites at a very low loading (0.1-5 wt.%).The results so far reported in the literature indicated that graphene/polymer composites are promising multifunctional materials with significantly improved tensile strength and elastic modulus, electrical and thermal conductivity. Despite some challenges and the fact that carbon nanotubes/polymer composites are sometimes better in some particular performance, graphene/polymer composites may have wide applications in dentistry due to their outstanding properties and the availability of graphene in a large quantity and at low cost.
Within the BIOGRAF project we plan to develop: ► a new nanocomposite material based on biocompatible polymers and graphene to be used in dental restorations ► new ex vivo tests to identify the host reaction to this material, in relationship with some biologic risk indicators. The final aim of the project is to develop modern and standardized therapies of caries lesions through the development of the novel nanocomposite material based on biocompatible polymers and graphene.
The present research project fits very well into the research domain 7. Materials, processes and innovative products since a new nanocomposite material with graphene will be manufactured which will fulfill the bio-safety criteria and have biocompatible properties with the local cellular environment. By its specific objectives BIOGRAF corresponds to the research thematic 7.1.6. Advanced materials and biomaterials for improving the quality of life (health, sport, education) because: ► a new nanocomposite material with graphene will be developed, for better medical treatments ► complex inter-/multidisciplinary studies will be performed, in order to elaborate and validate new standardized therapies based on advanced materials ►the development of a new perspective in dentistry, based on advanced theoretical and practical knowledge ► a research network will be developed which can ensure human resources for the top scientific research ► articles will be published in highly-ranked journals (ISI) ► research papers will be presented at international conferences ►valuable information will be disseminated among PhD/PostDoc students and researchers in the field of nanocomposite materials ►the equipments that will be purchased will develop the existing R&D infrastructure.
BIOGRAF project is aiming to deliver the following end-product(s)/ expected results:
► a new nanocomposite material with graphene, to be used in dental restoration therapy
► one laboratory technology for the synthesis of the nanocomposite material
►3 ISI papers, in highly ranked journals

Abstract:
DONTAS project presents the research, development and innovation of new tools, like surgical methods and techniques by using metal implants coated with smart composite layers based on advanced nanotechnology for medical applications. More specific, nanostructured phosphates (nanoPHOs), such as nano hydroxyapatite (nanoHAP) incorporating different additions of silicon as an osseopromotive agent, as well as magnesium and zinc requested for bone metabolism are synthesized and structural, morphological and biological characterized. Further smart composites, made of said nanoPHOs incorporated into natural polymers (collagen type I and/or chitosan) are developed to mimic the characteristics of natural bone. In addition, nanoPHOs are incorporated into synthetic polymers (PMMA or poly-Bis-GMA) for comparison with the above ones. Our preliminary results indicate a remarkably difference among morphologies of various DONTAS composites ranging from particulate matters to fibers mineralized with nanoPHOs. Also, metal implants are realized by a strong cooperation in DONTAS consortium, formed of two prestigious universities and two important national institutes, as well as a small and medium sized enterprise (SME). The metal implants are advanced processed to reach the surface characteristics to be well osteo integrated in bone. Furthermore, the surface of implants is functionalized by coating with DONTAS composite layers to efficiently promote the bond of the implant to the bone. This inventive project tackles the bioactivity of the above new composites assembled as scaffolds on implants (rods, intramedullary rods or plates), which will be thoroughly examined in cell cultures of osteoblasts. DONTAS surgical tools and smart composites will have large medical applications for repairing and replacement of bone in orthopedic surgery and in reconstructive medicine.

Abstract:
Demand for hydrogen (H2) will grow up in the next decades due to the technological advancements in fuel cell industry which permit its transformation in electricity and heat without generating polluting gases. At present, almost 95% of the world’s hydrogen is being produced from fossil fuel based feedstock. A more environmental friendly alternative is to replace fossil fuels by biofuels as raw materials for hydrogen production. Biomass is renewable and, although carbon dioxide is still produced, it may be recycled to new biomolecules by photosynthesis, resulting a carbon neutral cycle. An even more economical approach would be the hydrogen production from bio-fuels wastes. The main objective of this project proposal is to develop a laboratory scale technology and experimental set-up to produce hydrogen by steam reforming of hydroxylic compounds resulted as wastes in biomass processing or prepared from wastes of biomass. The main problem in the hydrogen production from glycerol wastes resulted in biodiesel fabrication process is the presence of impurities in crude glycerol which (i) impeded the performance of the catalyst and (ii) cause a severe catalyst deactivation. Our project proposes two approaches to overcome these problems: (1) to establish an economically viable method to partially purify the crude glycerol and (2) to test and find new multicomponent catalysts based on Ni with better activity and resistance to deactivation. A catalytic technology for hydrogen production from biofuel wastes and an experimental set-up at laboratory scale will be provided at the end of the project. The proposed project has strong interdisciplinary character which: (i) combines in a coherent manner knowledge from various fields: chemistry, heterogeneous catalysis, chemical reaction engineering, (ii) connects the fundamental and applicative research from National Institutes (CO and P2) and Universities (P1) with research developed by economical entities (P3) and by end-users of developed technology (P4).

Abstract:
Metal–organic frameworks (MOFs), a new class of crystalline materials exhibiting extremely high porosity, attracted attention as hydrogen-storage materials, similar to the best activated carbons at 77K. However, for applications in transportation a high H2 sorption capacity at ambient temperatures with low adsorption/desorption enthalpy are required. The promising results for room temperature H2 adsorption on MOFs composites with Pt/activated carbon recently reported were assigned to ‘‘spillover” effect but the controversy raised due to contradictory literature results is still open and needs to be solved due to its possible high impact on hydrogen storage.
The goal of the project is to assess the enhanced hydrogen adsorption reported in literature and to find new materials and methods to improve the H2 storage in solid state materials. New approaches for building the intimate contact at the interface of MOF with metal/support catalyst will improve the knowledge of the routes and methods with positive effects on hydrogen adsorption by MOFs based composites. Systematic studies will be performed on MOF/catalyst composites, employing alternative and complementary methods, with emphasis on: controlled ball-milling procedure, influence of the catalytic metal (Pt, Pd, Ni) or support, direct synthesis of different MOFs on catalyst, validation of hydrogen uptake measurements, identification of the major factors implied in the hydrogen transfer at the MOF/catalyst interface.
