Abstract:

This project aims to develop and test an experimental model for SOFC single cell with improved anode performance. An interdisciplinary partnership which brings together two institutions with complementary experience and capabilities in order to attain the project goal is created. Ceramic materials with improved properties will be used for the preparation of SOFC cermets anode. Based on previous research results, pyrochlore and cuspidine titanates with increased conductivity under reducing atmosphere will be used to obtain the cermet anode. The metallic component of the cermet will be nickel. Due to the improved electrical conductivity of the ceramic component, a decrease of nickel content in the cermet is expected. Thus, the degradation of anode performance during long term operation by nickel agglomeration can be diminished. Therefore, the outcomes of the project can ensure an increase of the SOFC system lifetime and performance. The results will be communicated at prestigious scientific events and published in high quality journals, increasing the international visibility of the research teams involved in this project.

Abstract:

The scientific and technical challenges facing fuel cells technology is the cost reduction and increased durability of materials and component. The challenges are substantial and require scientific breakthroughs and significant technological developments coupled with a continued social commitment. Therefore, our partnership proposes to undertake a two years research program with the aim to develop a unique fuel cells based energy system for portable applications. The fuel cells will be powered directly by bioethanol and will be in the electrical power range of 0.001-100w.

The development of an appropriate electrocatalyst to achieve high activity, high stability and high selectivity for the anodic oxidation of bioethanol in a micro-fuel cell power source will be the main outcome of the project. Surprisingly, there is a lack of data in the literature concerning the effect of non-noble metals on the activity of electrocatalytic materials. The project aims at filling this lack, by providing a low metal loading and low cost catalyst formulation to be used as anode in the fuel cell, and this makes ERGBIOGEN project new and original.

The project requires the close association and collaboration between experts in the fields of materials, catalysis, electrochemistry and engineering. This is fulfilled by the choice of the consortium, and therefore this project presents a collaborative consortium of four leading research groups from Romania, with complementary expertise.

Abstract:

Pollution and its side effects on health, structural damage of materials, costs for maintenance, cleaning and replacement of damaged materials is one of the most important causes of severe human diseases and of great economic losses all over the world. The project is focused on the development of new photocatalytic coating materials for technical textiles and architectural finishing systems that can be used to decompose pollutants in the air and on the coated surfaces in order to maintain a clean and healthy environment and avoid economic loses. The objective of the project is to obtain stable, adherent, efficient and durable daylight photocatalytic self cleaning coatings for different types of substrates, such as flexible technical textiles and rigid construction structures. To accomplish the objective, issues that require skills in various fields are to be addressed, in view of: scientific research for designing new photocatalysts, innovation activity for the improvement of their efficiency by extending absorption in the visible range of the spectrum, and technological development in order to obtain photocatalytic coatings dedicated to a particular type of substrate. All these issues will be solved due to a multidisciplinary partnership formed of high rank specialists in materials physics, laser physics, physical-chemistry, polymer chemistry, dyestuffs chemistry, and chemistry of textile materials, constantly having in mind obtaining safety products and technologies and achieving economic advantages from the production stage up to the application by the end-users.The method used for the synthesis of semiconductor materials is a key factor that determines their efficiency, the main reason for developing comparative studies regarding the most important oxide type photocatalysts used in practice (TiO2 and ZnO) that could be obtained and doped by wet methods (hydrothermal,sol-gel) or by laser pyrolysis route. Investigations developed in the project comprise also sensitizing the photocatalysts at the surface or by obtaining composites in order to use more efficient visible light in the photocatalytic decomposition of pollutants. Thus, we aim to develop new and optimized photocatalytically materials exhibiting activity upon visible light with surface characteristics of improved performance and of the high chemical and physical stability, crucial for broader scale utilization of photocatalytic systems in commercial application. However, another important challenge will be to obtain film building materials containing photocatalysts specially designed for coating technical textiles or for architectural coatings. Technologies regarding photocatalytic coatings developed in the project present several barriers that can be lifted by carrying out this project. The photocatalytic coatings that will be obtained will be compatible with the substrates, protect them to self-degradation and maintain their initial physical-mechanical characteristics, presenting high photocatalytic efficiency in visible light and durability. The newly developed photocatalytic coatings during the project will decompose air pollutants and other contaminants in outdoor and indoor applications using sunlight or artificial light, especially after expanding widespread use of LEDs for interior or exterior lighting of buildings, tunnels, advertising materials, thus making possible an enhancement of the photocatalytic effect and thus providing significant benefits for the environment and human health. Photocatalytic materials obtained in project together with the development of technically applicable photocatalytic coating systems adaptable to different types of substrates will represent a step change in this field particularly regarding the economic viability of a range of potential processes.

Abstract:

The aim of the project is the realization of an „electronic nose” for detection of very low concentration of pollutants and explosive gases. To obtain such a device, a microsensor array will be fabricated using integrated and miniaturized silicon based microtransducers. The microtransducers containing a microheater and interdigitated electrodes on top are built on a thin Si3N4 membrane suspended on four arms. The microsensor array will contain metallic-oxide based sensors, namely TiO2, ZnO and HfO2 nanostructured materials with special morphologies, with large surface areas, patterned on top of the interdigitated electrodes. These are one order of magnitude more sensitive than „normal materials” and able to detect very small quantity of gases. The novelty of the project consists: a) the significant improvement of properties of the proposed materials by controlling the nanometer-level architecture oxide (nanostructures) by forming ordered nanoporous structures, nanorods, nanotubes, spheres, and thin films with controlled morphology and porosity; b) new technology for microsensors fabrication with very low power consumption; c) using HfO2 nanotubes obtained by chemical methods for sensor application. The microsensor array based on TiO2, ZnO and HfO2 nanostructured materials will be tested as sensors for 7 gases: H2, CO, propane, NOx, NH3, CH4, H2S. The microsensor arrays will be encapsulated and coupled with an electronic module which will allow interfacing with a computer. A laboratory platform and a mobile apparatus for gas detection will be elaborated and tested especially for interior microclimates. The use of the microsensors together with information technology will improve these microclimates and will reduce their energy consumption.

Abstract:

The project proposal entitled “Improving oral and systemic health using dental restorations from modified alloys” is addressed to the priority field 4 Health and has as goal the improvement of oral and systemic health of the population through implementing new methods of prevention and intervention at national level having capacity of international expansion. Having the central objective the improvement of the health level mainly through the offer of medical services of prevention, the project will contribute to the reduction of costs in the field of health. The offer is elaborated under the competent and representative direction of the University of Medicine and Pharmacy “Carol Davila”, the Faculty of Dental Medicine, another 2 Universities, 1 Institute of research of the Romanian Academy and 2 co-financing SMEs. This consortium is by definition inter- and pluri-disciplinary and exhibits synergy and complementarity due to the contribution of Medicine, Chemistry and Biology to the achievement of the central objective and it shall benefit of the un-financed support of an European partner (Universita’ del Piemonte Orientale “Amedeo Avogadro”) well known in the field of oral pathology, partner which shall participate to the activity of research and dissemination of results. This partner with experience and tradition will enhance the chances of the project both at level of the choice of the best methods of prevention and intervention in oral health and also at the level growing the visibility of the research. As derived objectives to achieve the central goal, the project takes into consideration the formation of target groups of patients according to the following criteria of selection: the detection of lichenoid reactions, of a metallic pigmentary lesions; the existence of dental alloys (CoCr, CoCrMo, etc. used at mass level) which favoured the release of ions and the absorption due to materials imperfections. The project will also form proof-lots including in the study a high number of patients comprising also patients who did not use dental alloys, fact which will allow the set out of the cause of the diseases and of the most appropriate treatments for all the studied cases. Both the scientific background and the expertise of the 6 partners as well as the richness of human and material resources represent a warranty that it is possible to overlap the knowledge about the creation of an improved alloy (CoCrZr or Nb) capable to reduce the potential for serious diseases such as Lichen Planus. The project analyses the sick tissue and the amount of ions released chemically and biologically and to compare the behaviour of the existing materials with that of our new alloy. The improvement of the dental alloy will aim at both the composition as well as the surface state at micro- and nano- level. The trial of these materials will be performed in simulating conditions respecting the corresponding regulations form the European space of operation including the norms of bio-ethics and bio-security and the informed agreement of the patient. The results of the project will be disseminated and exploited both at level of health services as well as at level of co-financing partners who will develop technology and innovating dental works from improved alloys at reduced costs, fact that emphasizes the co-relation between the thematic of the project and the strategy of development of the SMEs partners. Obtaining a patent and publishing 5 research works in international publications of high impact is a prognosis of result indicators that complete the process indicators. The benefits of implementing the project and its exploitation after ending will grow the quality of life through precocious detection of diseases and their treatment and also through the proposal of a new less dangerous and less toxic alloy. The co-financing SMEs will develop as well the commercialisation capacity subsequent to the production of materials with high market potential.

Abstract:

The project entitled Innovative Materials and Processes for Selective Removal of Heavy Metals from Wastewater is included in the global concerns of humanity to have access to drinking water resources in the conditions in which water sources are becoming increasingly polluted. The most important anthropogenic sources of heavy metals are wastewater from various industries such as: electroplating, leather industry, textile industry, dyes industry, mining industry. Due to the fact that heavy metals are not biodegradable and they can be bio(accumulated) in living tissues, they can enter directly or through the food chain in human bodies, most of them being toxic, thus their removal from wastewater is currently imposed by legislative rules. Technologies to remove heavy metals from wastewater include precipitation, ion exchange, electrodeposition, membrane processes, sorption, sequestration by cementation. All these technologies have advantages and disadvantages (high operating costs, and for some of them obtaining sludges with heavy metals that will be stored and thus will determine soil pollution, or they will require further processing).

The project’s aim is to develop novel materials (nano- and micro-scale) with high selectivity for removal/retaining heavy metals from wastewater by solid phase synthesis, precipitation from aqueous solutions, and non conventional techniques such as sol-gel and microwave-assisted synthesis. The products obtained will be also as powder, beads, micro/nanospheres (hydroxyapatite, magnetite and chitosan), and compounds with complex structures like chitosan composites, chitosan cross-linked with glutaraldehyde, magnetite nanoparticles functionalized with organosilane and chitosan. The main purpose is to increase the selectivity, sorption capacity, durability and stability in acid environments, specific to wastewater.

Materials obtained will be tested in heavy metals (Pb(II), Cu(II), Ni(II) si Zn(II)) removal/retaining processes from synthetic solutions and industrial wastewater in order to identify the material with high selectivity and sorption capacity. There will be performed batch and continuous tests to establish the influence of factors (contact time, stirring speed, pH, size of adsorbent particles, height of adsorbent bed, metal ion concentration in the initial solution/wastewater, competition with other metal ions) on the sorption process. The kinetic and thermodynamic studies will be performed to establish the mechanisms involved in sorption process for industrial technology development.

Some of residual products resulted can be used in different industrial sectors such as: ceramics industry, building materials industry, and the others can be recovered by desorption processes and reused in other sorption processes. Materials and technologies proposed can be considered as main components of sustainable development of society due to the fact that they improve population health, protect the environment, reuse and integrate wastewater in natural and industrial cycles, create new jobs for young researchers, but also for people in urban areas, especially those affected by industrial pollution. The results obtained by the work performed in this project will be disseminated. The most relevant results will be used to apply for a patent proposal and for their industrial implementation. Research and development works will be based on moral and ethical principles according the deontology (Law 206/2004) endorsed by all partners in the consortium.

Abstract:

Energy production based on fossil fuels is one of the largest contributors to greenhouse gas emissions. Solid Oxide Fuel Cells (SOFCs) offer a great potential for increasing efficiency of power generation with additional environmental benefits. SOFC technology is currently under development. The state-of-the-art SOFC is operating at about 1000°C with high manufacture cost and low lifetime. The objective of the NANOBIOSOFC project is to improve this situation. Therefore, new chemical systems based on crystalline frameworks and porous architecture (with tailored structure, texture and morphology) and new cost-effective synthesis procedures will be developed in the framework of this project. The catalytic and electrochemical properties of the synthesized materials will be further investigated in order to select the appropriate preparation procedure and composition for each SOFC component (e.g. anode, electrolyte, and cathode), as well as the optimal operating conditions. Several thin film deposition procedures will be used for the manufacture of single SOFC. SOFC testing under various conditions will be carried out. Thus, the most appropriate manufacture procedure which allows the highest performance under long-time operation conditions will be identified. The expected impacts and outcomes of this project are:

- Integrate and develop new materials for improving SOFCs technology;

- Increase knowledge about the influence of composition, structure and processing conditions on the catalytic and electrochemical properties of nanomaterials;

- Gain understanding of component interactions and processes in single SOFC fueled with biogas.

Abstract:

The present project has as general scientific objective the developing of innovative green strategies polysaccharides-assisted for the design/synthesis of tailor made oxide-based nanomaterials, exploiting polysaccharides diverse and versatile properties (water-solubility, polyfunctionality, hydrophilicity, chemical reactivity, chirality, chelation/coordination, gelling, assembling and adsorption abilities). Precipitation, combustion, hydrothermal, forced hydrolysis and gel-templates methodologies will be elaborated in order to tune the size, morphology, structure and functionalization of the oxides materials. In these protocols, polysaccharides will be conditioned to act as: (i) stabilizers, (ii) templates (hard and soft), (iii) surface functionalizing agents and, (iv) carbon source. The developed synthetic approaches will use polysaccharides build up from D-glucose units linked by α- (starch, dextran) and β-glycosidic bonds (methyl-cellulose), with distinct polymerization degree, chain branching and rheological properties. ZnO, as well as ZnO/C and ZnO-polysaccharides composites of nanomeric sizes (50-300 Å) and various morphologies (including hierarchical and spherical structures as sphere, core/shell, hollow sphere, jingle-bell) and functionalizations are intended to be obtained. The assessment of a relationship with large degree of generalization between polysaccharide-synthesis-oxide represents benefits either from fundamental and applicative research points of view.

Abstract:

IN TISSUE ENGINEERING (TE) THE COMBINED KNOWLEDGE FROM BIOLOGY AND ENGINEERING

IS DIRECTED TOWARDS THE POSSIBILITY TO RESTORE LOST OR DAMAGED TISSUE. THE

GENERAL AIM OF THIS PROJECT IS TO CONSOLIDATE A CROSS-DISCIPLINARY TEAM OF

COLLABORATING INVESTIGATORS TO CARRY OUT SOME CELL-SUPPORT CONSTRUCTS (CSC)

WITH POSSIBLE APPLICATIONS IN REGENERATION/REPAIR OF SOFT AND HARD TISSUES AND IT

DOES NOT ASSUME PRE-CLINICAL AND CLINICAL TRIALS. THIS APPLICATION CONTAINS THREE

SPECIFIC OBJECTIVES: 1- OBTAINMENT OF NEW SUPPORT 3-D STRUCTURES DESIGNED TO

CULTIVATE OSTEOBLASTS AND HUMAN MESENCHYMAL STEM CELLS (HMSC) TO OBTAIN CSCS

WITH CHARACTERIZED ARCHITECTURE AND MECHANICAL PROPERTIES, USEFUL IN BONE TISSUE

ENGINEERING; 2 - DEVELOPMENT OF REGENERATION STRATEGIES OF ADIPOSE TISSUE BY

IMPLANTATION OF PREADIPOCYTES IN 3-D HYDROGEL SCAFFOLDS, THAT MIMIC

EXTRACELLULAR MATRIX, DESTINED TO THE RECONSTRUCTION OF SOFT TISSUE DEFECTS

(SEVERE TRAUMAS, DEEP BURNS OR TUMOR RESECTIONS) AND 3 - STUDY OF THE EFFECTS OF 3-

D CULTURE AND GROWTH FACTORS ON THE CHONDROGENIC DIFFERENTIATION OF HMSC CELLS

TO OBTAIN SOME INVESTIGATION MODELS OF THEIR POTENTIAL IN CARTILAGE TISSUE

REGENERATION. THE PROJECT PRESENTS VIABILITY, INNOVATION, COMPLEXITY AND

INTERDISCIPLINARY EXCHANGE BECAUSE: 1 - IT IS A CONSORTIUM WHICH CONSISTS FROM

PARTNERS WITH COMPLEMENTALLY COMPETENCES WHO ENGAGE TO ACT AS A UNITY IN THE

FOLLOWING FIELDS: CELLULAR AND MOLECULAR BIOLOGY, CHEMISTRY AND PHYSICS OF

MATERIALS, ENGINEERING SCIENCES – IN ORDER TO GET ALL OBJECTIVES; 2 - THE PARTNERS

ARE STAFFS WITH A GOOD, STRONG REPUTATION ON THEIR FIELD, AND THEY HAVE THE

NECESSARY MANAGERIAL EXPERIENCE AS WELL AS THE HUMAN RESOURCES AND PERFORMING

EQUIPMENTS AND 3 - THE PARTNERSHIP WAS PARTIALLY CONSOLIDATED DURING PREVIOUS

COLLABORATIONS AND WHICH SUSTAIN IT. ACCOMPLISHMENT OF THE OBJECTIVES OF THIS

PROJECT CONSTITUTES A SCIENTIFIC CHALLENGE FOR ANY SCIENTIFIC TEAM AROUND THE

WORLD.
