Abstract:

(Poly)saccharides represent ideal natural sources for the eco-friendly hydrothermal synthesis of semi-carbonized materials (hydrothermal carbons, HCs). HCs are nowadays considered alternative green conductive materials to more expensive graphene or carbon nanotubes (CNTs). The main objective of the proposal is the development of a new generation of sustainable electrochemical sensors constructed from Cu-based/(poly)saccharide-derived HCs composites. The engineering of HCs supports through hard/soft template strategies or the obtaining of HCs/CNTs hybrid structures gave rise to stable mesoporous materials with controlled pore structures that are expected to enhance the conductivity of the carbonaceous materials. The embedding of Cu-based nanoparticles into the HCs matrix or supported on the pre-designed porous HCs materials will lead to composites of which sensitivity toward several analytes will be tested. The social and environmental impact, relying on our scientific results, represent a step forward to a cleaner environment. The involvement of young researchers in our team will help them to acquire knowledge and new research skills and will also familiarize them with research themes related to green chemistry issues, like the minimization of waste and clean synthesis.

Abstract:

Novel biomaterials for temporary orthopedic implants are one of the most challenging areas of exploratory research in advanced materials. Third generation biomaterials are designed to be both resorbable and bioactive, that is, the implant will be temporary, and once implanted, it will help the body heal itself. The aim of this project is to progress toward a novel absorbable scaffold biomaterial for temporary orthopedic implants, through hierarchically structured surfaces that protect the scaffold, effective to convey higher corrosion tolerance and increased scaffold strength retention for extended periods in body fluids while at the same time capable to stimulate human osteoblast cell proliferation behavior. Specific objectives are (i) the design and fabrication of 3D printed scaffold structures with biocompatible elements by rapid solidification from melt through laser additive manufacturing-3D printing; (ii) the development of original cost-effective surface modification procedures for surface protected scaffolds (SPS) with enhanced corrosion tolerance and bioactivity; (iii) the determination of bare and SPS corrosion rates and corrosion mechanisms in human physiological fluids of pH and chloride concentrations reproducing the most exigent conditions for implant use; and (iv) the assessment of the scaffold-cell constructs to initiate tissue repair processes and osteogenesis; contributing to Romanian research with: 1 patent, 4 scientific articles, 6 conference presentations

Abstract:

The main purpose is the monitoring of greenhouse gases which are directly linked with the human activities. To this scope the project will develop a new technology for the fabrication of smart, miniaturized sensor array for greenhouse gases monitoring. A microsensors array based on alumina transducers and MOx (metal oxides) and polymer materials will be developed. The targeted gases considered as main contributors to the greenhouse effect, are methane, ozone, carbon dioxide and water vapors. The microtransducers are made up of alumina µ-chips with interdigitated gold electrodes on top (front side of the transducer) and platinum microheater on the backside. The microsensors array will contain undoped and doped MOx sensitive films (SnO2, ZnO, SnO2-ZnO, CuO) and polymers deposited by safe and low-cost chemical routes (sol-gel and hydrothermal method).

The novelty of the project consists of: a) the significant improvement of properties of the proposed materials by controlling the nanometer-level architecture oxide (nanowires) and by utilizing the multilayered mixed structure containing MOx and polymeric films; b) new technology for microsensors fabrication on thin alumina with very low power consumption. A laboratory platform and a mobile apparatus for gas detection will be tested. In Romania a project focused on monitoring of greenhouse gases, comprising detection, correlated with geographical and environmental conditions, data acquisition and interpretation is new. The two years duration will allow to optimize and to demonstrate the technology up to TRL 4, to fabricate the sensors (TRL 4), to start the data acquisition and interpretation. All these developments will allow a long-term prediction algorithm for pollution evolution, geographical mapping of areas with the highest pollution, prediction of local and global warming, under different RCP scenarios (Representative Concentration Pathways), monitoring of local evolution of these gases.

Abstract:

The project proposal “Functionalized mesoporous bioglass based 3D scaffolds for hard tissue regeneration“, aims to improve the well-being of people by treating them with new biomaterials. The objective of the project is to restore and improve the function of hard tissue by using functional bioactive scaffolds. These scaffolds will provide good mechanical properties in a suitable environment for tissue regeneration and repair. Sodium free mesoporous bioglasses (MBGs) doped with cerium will be used for scaffold manufacture using a combination of structure-directing agents and a polymer foam replication method. The BIOSCAFTIS project is based on our early results demonstrating that MBGs doped with cerium have good bioactivity and biocompatibility properties. In order to improve the growth and remodelling of bone tissue the surface of the scaffold will be functionalized with vitamin D3. The properties of the scaffolds e.g. bioactivity, mechanical strength, antimicrobial activity and drug delivery profile will be evaluated using adequate characterization techniques. The performance integration of 3D scaffolds to native tissues will be investigated using in vitro experimental models mimicking interaction with osteoblast cells. As a result of the research the project aims to disrupt the area of biomaterials by developing a new class of materials for medical applications.

Abstract:

The project aim is to obtain hybrid materials in form of enzymes/1D oxide nanostructures for enhancement of biodegradation process rates, leading to increased soil fertility. In order to achieve this scope, SiO2 (SiO2_NT) and sodium titanate nanotubes (TiNTs) will be functionalized with extracellular proteases, lipases and amylases of halophilic/halotolerant microorganisms isolated from Romanian saline environments, i.e. saline soils and lakes. Exoenzymes will be isolated, purified, biochemically characterized and immobilized on inorganic support (SiO2_NT and TiNTs). The efficiency of the hybrid materials will be tested for their biologically activity in native enzymatic form. The ability of the novel hybrid structures to contribute at the accelerating rate of biodegradation in experimental soil models will be also evaluated. The project is looking for obtaining reproducible data regarding the enhancement of enzymatic activity obtained by immobilization of extracellular protease, amylase, and lipase on tubular matrix of SiO2 and TiNTs. These results are meant to be a useful support for the biofertilization of intensively exploited or salted soils. Our project proposal is focusing on: (a) optimization of the textural properties of inorganic matrices (SiO2_NT and TiNTs) with respect to the further enzymatic immobilization; (b) modification of tubular surfaces with chemical active species in order to improve the enzymatic immobilization; (c) isolation of halophilic strains for targeted exoenzymes extraction; (d) tests regarding the adherence/adsorption of enzymes; (e) enzymatic tests with application in soils biofertilization.

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 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:

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:

The AWARE project topic is to establish an advanced conducting technique of controlling a clinker kiln operation in condition of waste recovery. The project topic lies within the 7.2 research area – advanced technologies to conduct industrial processes in the framework of the 7th domain – materials, processes and innovative products.

Due to a large number of variables which has an effect on both kiln operation and the quality of the clinker, is difficult to optimise the kiln operation, particularly due to variations in the feed material, fuel quality, burning conditions and other variables. Optimization is thus simply difficult to achieve manually or partially automated. The difficulty in manual or partially automated control is partly due to the difficulty in ascertaining what is going on inside the kiln, from both a process and a metallurgical point of view. This is practically a general problem, which is especially accentuated in high temperature systems where direct continuous industrial temperature measurement does not exist. Since, remnant features present in the clinker microstructure depend on the kiln feed variations and the burning conditions is understandable the strength of descriptive methods for particle shape and morphology quantification in optimization the clinkering process.

In order to overcome the above-mentioned issues CEPROCIM, UPB, ICF and CARPAT decided to join their efforts and skills in order to develop a solution to the problem of optimisation a process with a large number of variables which affect the operation of the kiln and the quality of the clinker. The practical purpose of the AWARE project is to implement the developed solution in a cement plant, which is the 3rd partner in the consortium.

In the AWARE project the research effort will be focused in the development of two end-products: a clinker microstructure model for high level control and an empirical relationship for prediction of 28-days compressive strength derived from experimental results of the first mentioned end-product.

The AWARE team decided to split the control of the clinker kiln in a multi-layered control levels where various control objectives are evaluated, the high level control consisting of clinker microstructure analysis using shape and morphology descriptors.

By cooperation between project partners, using the technique developed in this project, industrial partner CARPAT will be able to optimise the clinker burning process and in this way expand the environmental and economic benefits alongside the growth of the company. The estimated economic benefits measures in energy savings that could vary between 2.5% and 10% or in reducing CO2 emissions for environmental benefits.

The Work Plan is structured to lead all participants in a period of 24 months to carry out their activities with the best profitable resources management so to achieve the common objectives. The methodology followed during the project will be to put in close collaboration the industrial participant with the research performers, in order to develop the two end-products of the project.

Abstract:

Transparent conductive oxides (TCO) are materials that exhibit electrical conductivity and high optical transparency together with a wide band-gap. The traditional applications of these materials are flat-panel displays, light-emitting diodes, solar cells, and imaging sensors.

The aim of this project is the preparation by low-cost sol-gel methods of improved TCO (ITO, ZnO) and of new generation of TCO (Nb or V doped TiO2, SrCu2O2) n and p type films with various morphologies on different substrates (silicon, glass and plastics), having a very stable surface. A complete optical and microstructural characterization of the TCO samples will be performed by ellipsometry in a wide spectral range, from UV to Mid-IR (our IR ellipsometer being the only one available in Romania) and the results will be corroborated with those obtained by complementary methods (UV-VIS, IR and Raman spectroscopy, XRD, XPS, AFM, SEM, TEM, electrical measurements).

A database for optical constants of the TCO investigated materials in the IR range (2-33 microns), which for the moment is lacking in the literature, will be provided.

In the frame of this project the best films obtained will be used in specific tests for solar-cell application.
