Carbon Nanotubes for Applications in Electronics, Catalysis, Composites and Nano-Biology (CANAPE)

Objective: A major limitation on the application of the unique properties of carbon nanotubes has been their high cost and lack of availability. This IP brings together leading laboratories and companies within Europe to produce nanotubes on a bulk scale of ultimately tons per year. The large-scale growth of carbon nanotubes will be developed by chemical vapour deposition (CVD). The applications in electronics as interconnects and vias for integrated circuits, for field effect transistors, and spin coherent transport will be developed. Field emission will be developed further for use in microwave amplifiers and micron scale x-ray sources. Electronic applications will be enabled by controlled growth in plasma enhanced CVD and thermal CVD. Multi-wall CNTs will be used as a catalyst in large-scale chemical reactions such as the dehydrogenation of ethyl benzene to styrene. Control of the nanotube internal orientation to give the herring bone microstructure is needed for catalysis, as plane edges are catalytically active. Fictionalisation of CNTs will be extended, in order to improve the performance of structural, electrically conducting and thermally conducting nanotube-polymer composites. Dispersion of nanotubes at high loading will be achieved in polymers to obtain high strength composites. Nanotubes are known to act as high energy density actuators, or 'artificial muscles'. Nanobiological devices will be fabricated based on self-assembly and molecular absorption. A toxicological study of CNTs particularly with respect to possible health hazards will be carried out, and nanotube/polymer composites will be tested for biocompatibility. Public acceptance of nanomaterials and nanotechnology will be encouraged by publicity and poling. Training, workshops and conferences will be held, and to promote technology transfer from universities and research institutes to companies. SMEs will be dominant in the CVD, catalysis and composite applications

PoroElastic Road SUrface: an innovation to Avoid Damages to the Environment (PERSUADE)

Objective: Low-noise road surfaces are recognized as a cost-effective tool for traffic noise abatement. The best performance can be achieved by optimizing surface texture and porosity. That way, a bottom line of a 3dB lifetime average reduction with respect to ordinary asphalt has been reached. Any progress must resort to another noise-relevant characteristic i.e. elasticity by which the noise due to tyre vibrations can be suppressed. A recently completed European project has shown that, in order to be effective, the elasticity of the road surface must be in the same range as that of the tyre itself. This explains why previous attempts of incorporating a little rubber in an asphalt mix failed to produce significant noise reductions. The solution consists of a fully rubberized, porous compound: a so-called.

Plasma And Nano for New Age 'soft' conservation (PANNA)

Objective: The main objective is to develop a novel atmospheric plasma technique for surface cleaning and coating deposition as well as two innovative coatings: a self-diagnostic protective coating and a coating provided with identification marker. The project aims at integrating the new plasma cleaning/deposition technique and the new coatings in a full-life protocol spanning surface cleaning and pre-treatment, deposition of protective and identification coatings, and complete removal of coatings. The plasma technique is proposed for surface cleaning and coating removal as alternative or complementary to the other non-contact techniques such as laser. This technique is characterized by no thermal heating, selectivity, chemical reduction of oxides, applicability on all substrates and competitive costs. The self-diagnostic coatings provide a long-lasting solution with an added value of easy and instant diagnostic of coating functionality through a nano-technological approach, reducing monitoring costs and time with no impact on tourist accessibility. The identification marker coating allows using nanotechnologies to obtain a transparent authenticity proof and cataloguing label. The compatibility of the new materials with the substrates is guaranteed intrinsically by their integration in the full-life protocol because it ensures its complete reversibility. The protocol is applicable on all substrate materials principally as preventing conservation, in the project its validation is proposed on metal substrates (silver and bronze) and on mural paintings, limestone and sandstone. The project also aims at implementing a demonstrator of the entire full-life protocol, which will be used for training cultural operators in organised events and fairs. An added value is also the strong participation of SMEs as conservation operators and as technological companies, which ensures the possibility of scaling up and placing the new products on the market.

Lithium-Air Batteries with split Oxygen Harvesting and Redox processes (LABOHR)

LABOHR aims to develop Ultra High-Energy battery systems for automotive applications making use of lithium or novel alloy anodes, innovative O2 cathode operating in the liquid phase and a novel system for harvesting O2 from air, which can be regenerated during their operative life without need of disassembling. LABOHR has 5 key objectives: (i) development of a green and safe electrolyte chemistry based on non-volatile, non-flammable ionic liquids (ILs); (ii) use of novel nanostructured high capacity anodes in combination with ionic liquid-based electrolytes; (iii) use of novel 3-D nano-structured O2 cathodes making use of IL-based O2 carriers/electrolytes with the goal to understand and improve the electrode and electrolyte properties and thus their interactions; (iv) development of an innovative device capable of harvesting dry O2 from air; and (v) construction of fully integrated rechargeable lithium-Air cells with optimized electrodes, electrolytes, O2-harvesting system and other ancillaries. Accordingly, LABOHR aims to overcome the energy limitation for the application of the present Li-ion technology in electric vehicles with the goal to: 1- perform frontier research and breakthrough work to position Europe as a leader in the developing field of high energy, environmentally benign and safe batteries and to maintain the leadership in the field of ILs; 2- develop appropriate electrolytes and nano-structured electrodes which combination allows to realize ultra-high energy batteries; 3- develop a battery system concept as well as prototypes of the key components (cell and O2-harvesting device) to verify the feasibility of automotive systems with: A) specific energy and power higher than 500 Wh/kg and 200 W/kg; B) coulombic efficiency higher than 99Prozent during cycling; C) cycle life of 1,000 cycles with 40Prozent maximum loss of capacity, cycling between 90Prozent and 10Prozent SOC; and D) evaluate their integration in electric cars and renewable energy systems.

Intelligent Mobile Multipurpose Accurate Thermoelectrical (IMAT) Divice for Art Conservation (IMAT)

Objective: The IMAT project aims to integrate the cutting edge research in nanotechnology with that of cultural heritage conservation for the development of new advanced conservation techniques and materials. A consortium of researchers representing expertise in the areas of art conservation, nanotechnology, and thermo-electrical engineering, has been assembled with the purpose of inventing an advanced precision heating technology and designing a series of portable, highly accurate flexible mild heating devices specifically for broad application in the field of art conservation, employing, but not limited to the new technology of carbon nanotubes (CNT). The new technology and product acknowledges and responds to a glaring omission in fundamental conservation instrumentation. The control over the application of heat often constitutes the core of success in structural treatment of diverse cultural heritage objects, yet sources currently available to conservators are unable to guarantee accuracy, control or uniformity, and therefore may compromise the favourable outcome of treatment. The lack of mobile high precision and accessible instrumentation impacts conservation treatment capacities and the long-term preservation of irreplaceable cultural heritage in the most direct way, since objects may be and are exposed to risk because of inadequate or unavailable instrumentation. This is particularly relevant to treatments that take place in the field, including emergency responses, that often must rely on inadequate tools. The heating table, long considered a basic piece of laboratory equipment for previous methodologies, is now out of sync with the current direction of conservation that favours minimally invasive treatments with respect to those of the past and requires enhanced mobility and versatility. The IMAT goals therefore will hit the core of this problem in many ways and the results will have a lasting impact on conservation methodology and beyond. The unique properties of carbon nanotube (CNT) materials will allow for the design of thin, lightweight, even transparent, stretchable and woven mild heaters with low power needs as an ultra-portable, versatile and efficient alternative for diverse thermal treatments. The development of the IMAT device and methodology will represent a unique opportunity to impact the field of conservation of heritage products in a significant manner, and the full extent of the potential for application will become evident only during usw.

Advanced Fluorinated Materials for High Safety, Energy and Calendar Life Lithium Ion Batteries (AMELIE)

The focus of the project is on the development of fluorinated electrolyte/separator and binders in combination with active electrodes (anode LiC6 and cathode: LiNixMn2-xO4 - 4,7V) for high performing, safe and durable Li batteries. The main deliverables of the project are the development of cell prototypes capacity greater than 10 A.h on which performance assessment will be conducted. The AMELIE prototype performances will be assessed towards the following objectives for EV and PHEV applications: high specific energy: cells greater than 200 Wh/kg, improved life time: greater than 1000 cycles, 80Prozent DOD for EV applications, High calendar life: greater than 10 years, high recyclability / recovery/ reuse: battery components 85Prozent recycled and improved competitiveness: less than 500 Euro/kWh on prototype paving the way for mass production cost less than 150 Euro/ kWh. The utilization of higher performing 'inactive' organic materials (polymers and ionomers) will enable to reduce the amount of the same materials while increasing the energy and power densities of the battery, and consequently decreasing the cost per kWh of the final battery. In addition, the reuse of the components will contribute to the cost reduction of the battery. To this end a complete Life Cycle Analysis of the new battery components will be performed. To take up these challenges, academic and private organisations have partnered up in the AMELIE consortium. As the developments in this field are extremely interconnected, improved Lithium ion batteries for automotive sector can be manufactured only by the synergistic optimisation of all their components: active materials and binders for electrodes, gel polymers, lithium salts and solvents for the ionic conductors. Although innovative materials are a key lever of such improvements, the cell design will be essential for both improved performances and safety.

Advanced turbulence simulation for aerodynamic application challenges (ATAAC)

The ATAAC project aims at improvements to Computational Fluid Dynamics (CFD) methods for aerodynamic flows used in today's aeronautical industry. The accuracy of these is limited by insufficient capabilities of the turbulence modelling / simulation approaches available, especially at the high Reynolds numbers typical of real-life flows. As LES will not be affordable for such flows in the next 4 decades, ATAAC focuses on approaches below the LES level, namely Differential Reynolds Stress Models (DRSM), advanced Unsteady RANS models (URANS), including Scale-Adaptive Simulation (SAS), Wall-Modelled LES, and different hybrid RANS-LES coupling schemes, including the latest versions of DES and Embedded LES. The resources of the project will be concentrated exclusively on flows for which the current models fail to provide sufficient accuracy, e.g. in stalled flows, high lift applications, swirling flows (delta wings, trailing vortices), buffet etc. The assessment and improvement process will follow thoroughly conceived roadmaps linking practical goals with corresponding industrial application challenges and with modelling/simulation issues through stepping stones represented by appropriate generic test cases. The final goals of ATAAC are: - to recommend one or at most two best DRSM for conventional RANS and URANS- to provide a small set of hybrid RANS-LES and SAS methods that can be used as reference turbulence-resolving approaches in future CFD design tools - to formulate clear indications of areas of applicability and uncertainty of the proposed approaches for aerodynamic applications in industrial CFD - Contributing to reliable industrial CFD tools, ATAAC will have a direct impact on the predictive capabilities in design and optimisation, and directly contribute to the development of Greener Aircraft.

Cellular interaction and Toxicology with engineered Nanoparticles (CELLNANOTOX)

Objective: The present proposal aims at the development of innovative multidisciplinary sets of tests and indicators for toxicological profiling of nanoparticles (NPs) as well as unravelling the correlation between the physicochemical characteristics of NPs and their toxic potential on various organs of the human body. For a comprehensive understanding of the complex data to be obtained on toxicology of NPs, based on in-vitro and ex-vivo studies, we will employ conventional toxicology combined with the methodologies of toxicogenomics, metabonomics, Knowledge Discovery from Data (KDD) and Data Mining (DM). This research program is focused towards understanding the relation of size and surface chemistry on the deposition, uptake, translocation, and toxicity of a few s elected industrially important NPs as well as novel synthesized NPs, whose size and surface chemistry will be methodically modified. Since it was shown that the penetration of NPs into the human body proceeds principally through inhalation or orally, whereas penetration through healthy skin is restricted, we have chosen lung and intestine as the primary interacting tissues/organs with NPs, while liver, kidney and the immunological system have been selected to be the secondary major sites of interaction, following the penetration of NPs into the blood circulation. The interaction of the NPs with these different target organs will be studied by making use of alternative methods to animal experimentation by employing in-vitro cell systems as well as ex-vivo studies based on precision-cut slices of lung, liver and kidney. The present proposal addresses the needs of the European society for assessing the risk of occupational and general population exposure to industrially manufactured NPs. It will generate new knowledge on potential health risk or the absence of it, providing objective arguments for recommendations and regulations.

Development of a platform and toolkit for understanding interactions between nanoparticles and the living world (NANOINTERACT)

Objective: We combine state-of-the-art techniques, methodologies, skills and instrumentation from several scientific arenas to create discipline-independent platforms to address key questions in nanotoxicology. Thus, we identify the routes via which nanoparticles enter and accumulate in living organisms, and connect this to representative cell-nanoparticle systems. Then using the most advanced methods of chemical, physical, biological and toxicological sciences we connect nanoparticle properties (in physiological conditions) to the mechanisms via which they interact with, and disrupt, cellular processes. We establish means and protocols via which every step of the program will be controlled, eliminating the factors that currently cause irreproducibilities. We emphasize novel unbiased assessments of intra- and inter-cellular processes after exposure to nanoparticles, enabling us to explore known, and unknown, processes. Key companies, large and small from several end-user groups, that are currently facing the challenge of applying nanotechnology in their products are built into the program in a substantial manner, and other key stake-holders are also incorporated into the overall consortium via the Advisory Board. This will ensure maximum uptake of the knowledge generated by NanoInteract, and enable development of Standards for nanoparticle risk assessment.
