Abstract:

In recent years, bone tissue engineering has been primarily concerned with finding new biomaterials with superior properties or improving the characteristics of those already on the market. Due to their excellent mechanical properties, high biocompatibility, and satisfactory corrosion resistance, titanium and its alloys are usually recognized as the predominant materials for implants. However, the titanium surface is bioinert, which makes it difficult to actively regulate bone healing processes in the early stages of implantation. In addition, Ti implants are exposed to surface corrosion and wear, which can lead to implant failure. The general objective of the Pho-Tim project is to improve the biological response of Ti implants by depositing on their surface phosphate layers based on Zn-Ca-Mg, Zn-Ca-Zr, and Zn-Mg-Zr through chemical conversion. These layers will improve the corrosion and wear resistance of the titanium alloy implants, as well as promote osseointegration and biocompatibility. Thus, the project includes activities to obtain and characterize phosphate layers deposited by phosphating on titanium alloy surfaces, as well as their validation for biomedical applications. The Pho-Tim project aims to eliminate the disadvantages of titanium implants by having a substantial impact on the patient's healing time and decreasing the risk of implant failure.

Abstract:

The aim of the project is to evaluate the protective role of ceramic layers made of Metco 207 powders (yttrium-stabilized zirconium oxide material with a high yttria content) deposited on

an Inconel substrate to find a thermal barrier through which the life span can be extended of the turbine blades by using a new material, easier to process and which, deposited by modern

methods, improves the thermomechanical behaviour of the blades, increases their performance at high temperatures and prevents exfoliation. The purpose of the tests that will be performed on

the samples obtained by plasma deposition technologies is to obtain the data necessary for the preliminary evaluation of their properties. In this sense, the conditions that the samples deposited

with ceramic coatings must meet must be as close as possible to their operating conditions. Thus, the similarity between the test and the method of exploiting the achieved coatings becomes an

essential condition for the success of a more accurate evaluation. Another basic requirement of a good preliminary test is to ensure the reproducibility of the data and its validity for predicting the

maximum performances of the coatings.

Abstract:

The project proposes the use of a novel environmentally sustainable concrete for energy efficient buildings. A prototype model will be built in the frame of the project after a series of test will be conducted at material level and then moving to a scaled-down 3D model of a building. The project aims at proving the efficiency of the sustainable concrete both from the point of view of energy savings for heating and cooling and from the points of view of its behavior during significant seismic events. The environmentally sustainable concrete was developed starting from the principles and experimental programs conducted in terms of using supplementary cementitious materials and the use of perlite aggregates for reduced self-weight and improved thermal properties.

Therefore, the proposed project starts from TRL3 and ends at TRL4 with a scaled down 3D prototype model being build and tested in laboratory conditions. The envisaged tests will give valuable information in terms of mechanical properties, thermal insulating characteristics, CO2 emissions generated by the material and the seismic behavior.

A particular attention will be paid to the dissemination of the results in terms of scientific publications and in terms of continuously keeping interested industrial partners updated with the benefits of adopting an alternative solution to the classical building materials.

Abstract:

The project " Novel Mg-Ca-Zn biodegradable metallic materials used in orthopedic applications " proposes the elaboration of biodegradable materials from the Mg-0.5Ca-xZn system for use in medical implantology. In the last decade, many researchers have made progress on biodegradable Mg-based alloys with applications in medicine. The unique chemical composition of these alloys offers all the premises of promising results regarding bone regeneration and the elimination of the 2nd surgery. The use of these elements leads to a considerable increase in corrosion resistance, biocompatibility and mechanical properties. The project has a strong multidisciplinary character, due to the complexity of the the studies will focus on testing this class of biodegradable materials through microstructural analysis (OM, SEM and XRD), tribological tests, electrochemical behavior in SBF, cell viability tests (in vitro analysis –MTT method) and in vivo analysis on laboratory model animals. These results will contribute to the certification of the preliminary information obtained and the confirmation of the controlled and biocompatible biodegradable character of the Mg-0.5Ca-xZn alloys used in orthopedics. The project aims to identify an optimum concentration of the Mg-0.5Ca-xZn system, to publish the results in international journals with ISI impact factor, to submit the patent documentation and to identify the users and manufacturers of biocompatible materials for the technological transfer.

Abstract:

The ROBIM project MicroLIBS sensors for robotic planetary and astrobiological exploration missions is focused research, to design and validate miniaturized equipment able to working in exploratory space missions with severe constrains (environment gas mixture, pressure, temperature, etc). Our technology is based to enhance the ablative and emissive stage of the plasma by means dual-pulse LIBS in order to enhance the analyte peak-to-base and signal-to-noise ratios, and atoms and ions line spectra. Taking into account the advantage of dual pulse LIBS technology, choosing various wavelengths and a high repetition rate of the lasers, we propose an instrument able to remote the chemical compounds behaviors in various environmental conditions based on the measurements obtained not only by LIBS but also by Raman coupled spectra according to each used laser. The obtained Raman spectra are dependent on time profile of the plasma plume and consequently we enhance the potential of the LIBS to investigate furthermore the phase changes and trace compound especially in the ice/soil mixture samples (depending on the temperature). Following, time-space resolved emissions Raman Spectroscopy is used to measures in a second the elemental compositions of the soil/rock.

Abstract:

The Horizon 2020 framework is stressing the importance of nanotechnologies and nanomaterials and is aiming to exploit their potential for sustainable growth, competitiveness, environment, highly skilled jobs and increased quality of life. In this context, electrospinning has attracted significant attention as a commercially viable route to fabricate nanofibers for a large number of industrial applications, including filtration media, electronics, biomaterials, and clinical medicine, etc. TECHMAT’s main goal is to achieve enhanced control of the electrospinning process through technological innovation which will lead to much needed diameter uniformity of the produced fibers so that the electrospinning process can be rendered reproducible and reliable for both scientific modeling and industrial applications.

We will start from a technological concept at Technology Readiness Levels (TRL) 2 supported through previous projects, publications and patents of the TECHMAT consortium. Our aim is to reach a TRL4 level of development validated under experimental laboratory conditions by the production of nanofibers and comparison of their properties with previous results obtained by the consortium.

The aim is to exploit, through academic-industry collaboration, the innovation in basic research within the TECHMAT consortium in order to produce viable technological solutions as well as novel products and services. The project results will be exploited through: (1) A patent application to protect the consortium’s IPR; (2) technological transfer towards the involved SME of a functional laboratory model for control with a relatively short (1-2 years) estimated time to market, (3) high impact dissemination to the scientific community (scientific articles, monographs, conferences, fairs, exhibitions) and (4) dissemination through mass-media towards the non-scientific communities.

Abstract:

NanoAir project contributes by providing additional and original data related to physical-chemical properties of atmospheric aerosols including a synergy between inversion products of remote sensing techniques, analytical microscopy and nanoscale imaging & spectroscopy. NanoAir aims to bring complementary and original responses by using for the first time the most advanced scattering-type Scanning Near-field Optical Microscopy (s-SNOM), which combines Atomic Force Microscopy with optical imaging and spectroscopy at the nanoscale (nano-FTIR) in order to better understand the fundamental of some critical physico – chemical transformation of the atmospheric aerosols (pollutants) but also for applications point of view. NeaSNOM nano-FTIR technology is a powerful tool for cutting-edge nano-analytic applications, allowing for nanoscale imaging and nano-FTIR spectroscopy with outstanding spatial resolution down to 10 nm. NanoAir results will be correlated with atmospherically conditions and inversion products in order to fully understand the effects on the optical properties of thinly coated soot aerosols and how ns-soot is coated by, attached to, or embedded within other pollutants. Additionally, NanoAir concept will be dedicated according to the scientific objectives of the international networks (GAW, ACTRIS, AERONET etc.) in order to provide trustworthy absorption characteristics for predominant aerosol light absorbers of anthropogenic and natural origin, targeting the needs of the modelling, in-situ and remote sensing communities. NanoAir will optimize the aerosols component by improving the existing collaborations and infrastructures, data processing and quality assessment, implementing additional observation capabilities and new data products and thus NanoAir will provide new tools to fully exploit the products capable of contributing to aerosol and climate research.

Abstract:

The present proposal aims to investigate the factors that enhance the occurrence of SE in FeMnAlNi SMAs, by comparing their response to the superelastic behaviour of FeNiCoAlTaB, taken as a reference. In the first stage of the project, ingots will be produced by vacuum induction melting in cold crucible, with the following chemical compositions: Fe40.95Ni28Co17Al11.5Ta2.5B0.05 and Fe43.5Mn34Al14;15;16Ni7;7.5;8. The ingots will be cut, hot rolled to the thickness t= 0.5-1 mm and heat treated, with the aim to enhance the abnormal growth of crystalline grains, in FeMnAlNi SMAs. FeNiCoAlTaB SMAs will be cold rolled and solution treated (12500C), meant to cause a strong {035} texture. After heat treatment, the average size (D) of crystalline grains will be determined by optical microscopy observations. The aim of this heat treatment is to obtain “bamboo type” oligocrystalline structure characterized by D/t > 1 and the absence of triple junctions between grains. From oligocrystalline samples, in the second stage of the project, specimens will be cut for tensile tests and dynamic mechanical analysis (DMA). Tensile loading-unloading tests will be performed at different temperatures and the recorded stress-strain curves will be analysed. The reversible force variation with strain amplitude, during dynamic cycles, will be analysed by strain sweeps performed on DMA, using dual cantilever specimen holder. In the third stage of the project, both FeNiCoAlTaB and FeMnAlNi specimens, that experienced tensile SE, will be subjected to thermal and structural analysis. The former will be done by differential scanning calorimetry for determining the critical transformation temperatures and the latter X-ray diffraction, scanning electron microscopy coupled with electron backscatter diffraction and transmission electron microscopy aiming to observe the presence of coherent precipitates and to correlate their morphological fluctuations with technological factors.

Abstract:

The project describes the manufacturing process of an original multifunctional device, generating linear displacements for self-adaptive compensation of the clearance caused in some machine parts under functioning conditions. The prime novelty of the project are the active elements produced by Fe-Mn-Si shape memory alloys (SMAs) with ultrafine/nanometric structure, obtained by severe plastic deformation procedures, meant to enable both fragile-ductile transition and high temperature stability through structural heredity. Fe-Mn-Si SMA elements will undergo “training” thermomechanical processes which induce the final behavior of the materials with temperature or stress variations, thus acquiring a quantifiable multifunctional potential (expressed via work). Strain recovery by shape memory effect, under prescribed temperature conditions, allow displacement development as an effect of the deformation of lamella and/ or disk-like elements. The manufacturing technology of the elements includes the setting of two “shapes” by conventional plastic deformations. The “hot” shape corresponds to the parts deformed within the austenitic domain through deep drawing with a curvature radius r0 which depends on the shape memory properties of the material, while the “cold” shape involves a deformation in martensitic domain with a curvature radius r > r0, inversely to hot deformation. With temperature increase, trained elements behave like actuators which recover their “hot” shape by work development, according to an accurate linear self-adapting displacement. The association of trained elements in the framework of coupled modules provides flexibility and multifunctional character to the developed system. The general purpose of the project is to promote an advanced technological solution for producing some elements with role of self-adaptive actuators and for their assembling within an original functional-constructive variant, able to generate accurate controlled displacements.

Abstract:

Laser-induced surface polymer deformation, laser-surface polymer relief grating formation (SRG), laser- ablation both of photochemical polymer but also of doped polymer processing, pulse laser deposition (PLD) have been the object of growing interest due to potential in nonlinear optics (NLO), laser direct patterning (LDP), fuel in the micro laser plasma ablation satellite propulsion thruster (μALPT), and biocompatible metal-doped polymers. The laser polymer ablation mechanism is a complex interrelated system where the photochemical and phototermal reactions are very important. The photopolymers which interaction with the coherent laser beam create a diffraction pattern and then by means of intermolecular forces transmit the pattern to the all their surrounding neighbors. This pattern is the active part of the self-organized structure ensuring the exchange information inside the locally domain. The microstructure determination of the photopolymers and the presence of surface relief gratings and micro/nanostructured aggregates in thin films and solutions will be evidenced by fluorescent and absorption UV-Visible spectroscopy, FT IR spectroscopy, AFM technique, SEM and XRD analyze. The evolution and dynamics of the well structured plasma plume will be investigated by means fast ICCD image plasma plume, laser induce fluorescence (LIF), particle image velocimetry (PIV, time-resolved shadowgraphy & interferometry and Langmuir probe electrical plasma diagnosis.

Abstract:

The project aims to analyse the limits up to which atomic migration allows the thermally induced reversion to parent phase of stress-induced martensite (SIM), in porous Fe-base shape memory alloys (SMAs). The experiments will be performed on hot-rolled (HR) specimens obtained by powder metallurgy (PM) processing, comprising pressing and sintering as blended elemental powders mixed with various amounts of mechanically alloyed (MA) powders (0-40%MA). Technically, HR PM-MA specimens will be cut by spark erosion into 3 configurations: (i) an original shape for tensile-calorimetric (Tens-DSC) experiments; (ii) “dog bone” profile for tensile tests (Tens) and tensile-X-ray diffraction (Tens-XRD) experiments and (iii) lamellas (Lam) for dynamic mechanical analysis (DMA) tests. All profiled specimens will be solution treated between 800 and 1200 degrees Celsius. After determining tensile behaviour of Tens specimens by means of the failure curves, Tens-DSC and Tens-XRD specimens will be pre-strained between 0-5%, in order to form SIM. Phase structure of Tens-XRD specimens will be analysed on XRD patterns and by optical and electron microscopy, while atomic migration will be investigated by energy dispersion of X-ray and focus ion beam (EDX-FIB). During thermally induced reversion of SIM, thermodynamic response will be analysed by DSC, on Tens-DSC specimens, while thermomechanical response will be emphasized by DMA, on Lam specimens, subjected to strain sweeps at various frequencies.

Abstract:

Among the prevalent high damping metallic materials, shape memory alloys (SMAs) could be one of the most promising candidates due to their high damping capacity arising from the reversible martensitic phase transition (MT) and the stress induced reorientation of martensite variants. Damping materials have many applications in all domains connected to amortizations, energy dissipation or structures rehabilitation. Thin shape memory alloys films were used in different micro-actuators applications to exhibit memory effect but not until now as layers for damping capacity improve. The project propose few copper based shape memory alloys (CuMnAl, CuZnAl, CuAlNi with nano-particles additions) as targets for a pulsed laser deposition (PLD) equipment to improve a superelastic material properties. PLD process of SMAs represents a difficult target concerning the complex processes that occur during this technique but the resulted layers have very good wearability and adhesion properties. Using thermal, microstructural, chemical and mechanical analysis methods (DSC, DIL, DMA, SEM, AFM, XRD, XPS) the shape memory alloys as bulk for targets, the superelastic substrate and after deposition the new material obtained will be investigates to establish the modifications between these cases of the material. The application author experience in memory effect field and especially in high damping shape memory alloys and the knowledge of the mentor in plasma field sustain this theme finalization.
