Abstract:
The main goal of the project is the obtaining of new soft magnetic composites (SMC) with improved properties which could be used like magnetic cores at medium and high frequencies. Innovative idea is to replace in SMC the non-magnetic dielectric (polymer, used in classical SMC) with a magnetic dielectric (magnetic ferrite). The project is structured on three directions (objectives): (i) obtaining of nanocrystalline/nanostructured SMC powders, (ii) obtaining the nanocomposite compacts by spark plasma sintering and by cold sintering in order to preserve the phases composition and nanocrystalline state and (iii) study the balance between magnetic and electrical properties of the SMC sintered compacts. The powders will be produce by: (a) milling of mixture of alloy (ductile) and ferrite powders (brittle) to obtain the nanocomposite particles like “raisin bread” model, (b) micro-alloying between the large particles of magnetic alloy surrounded by nanosized ferrite particles (pseudo core-shell particles) and (c) obtaining by chemical method the core-shell powders (core – iron, shell - Fe3O4). The proposed research aims to optimize the microstructure influence on the magnetic coupling and electrical resistivity in nanocomposite powders and sintered compacts. The balance between magnetic and electric properties in correlation with structure/microstructure and interphase studies will be shown by a diagram of the Saturation (and/or Permeability) - Electrical resistivity.

Abstract:
Anemia is a global issue affecting 2 billion people. Over 52% of pregnant women suffer from anemia. Scientists' bigger concern is iron bioavailability and gastrointestinal side effects. A promising approach for anemia treatment is the utilization of iron oxide nanoparticles. We will empower the iron oxide nanoparticles with probiotics from Lactobacillus and Bifidobacterium species, leading to a reduction of gastrointestinal discomfort, an increase in iron absorption and reduced problems pose of toxicity.
Our overall objective is to design, develop and test an innovative probiotic (Lactobacillus and Bifidobacteria) carrier iron oxide nanoparticles suitable for i) anemia treatment with ii) minimum side effects (no cytotoxicity) that sustain iii) optimum iron absorption mechanism and iv) ensure the gut microbiota health, in order to maximize their impact. Specific objectives will be achieved through seven work packages (WP1-7):
WP1-Synthesis and characterization
WP2-Functionalization
WP3 -In vitro simulated gastrointestinal interventions
WP4-In vitro cellular uptake and cytotoxicity
WP5-In vivo validation of the anemia treatment using probiotic iron oxide nanoparticles
WP6-Scientific and social innovation, dissemination, communication & exploitation
WP7-Management
The potential impact on budgets for health care is considerable; considering that over 30% of the population is anemic, many due to iron deficiency. The research will encourage an interdisciplinary approach.

Abstract:
The scope of the project is to obtain soft magnetic composite – SMC materials based on alloy (Supermalloy and Sendust)/oxide (mainly spinel ferrites) composite powder and use them for production of magnetic cores that can work in frequencies for energy efficient electromagnetic applications. The specific applications that is envisaged for these magnetic materials are magnetic cores that can be used in transformers/inductors for energy/power conversion. The product is falls in line with the tremendous trend for miniaturisation and energy saving, increasing the energetic efficiency. The project proposes two types of magnetic cores: a composite sintered one - oxide matrix with metallic clusters embedded and a polymeric matrix one using metallic@oxide composite powder. The project will be developed by a multidisciplinary research team involving materials science and engineering specialists, chemist and electrical engineers. The synthesis of the magnetic cores involves the preparation of composite powder of alloy@oxide, double layered composite particles allloy@oxide@polimer and composite powder compaction/densification, especially by spark plasma sintering. The composite magnetic cores will be tested in frequencies, energy efficiency will be tested (magnetic losses), will be characterised from structural, microstructural, thermal stability, electric and magnetic point of views.

Abstract:
The main objective of the project consists on the study and the elaboration of new generation spintronic devices with applications in sensor/data storage technologies, whose operation is based on innovative low consumption magnetization manipulation. Its attaining implicates a deep understanding of the underlying physics related to magnetism, spin and charge transport in multilayered thin film mesoscopic structures constituted by complex materials with tailored functional properties. Moreover, delicate technological issues have to be precisely mastered: multistep lithography patterning of spintronic pillar devices with electronic transport perpendicular to the layer’s plane and lateral sizes within the nanometric to micrometric range. The elementary brick of the targeted sensor is the MTJ, based on thin films materials with tailored functional properties. The manipulation of the MTJ magnetization is scheduled to be performed following two mechanisms: (1) the voltage-controlled electric field (E-field) effect on anisotropy and (2) the spin-transfer torque (STT) effect induced by spin-polarized current. While the STT mechanisms have been widely studied in the last decade and already led to novel generation of nonvolatile magnetic random access memories (STT-MRAM), from fundamental point of view, our study surveys the E-field magnetization manipulation. Therefore, we aim to shed light on the complex charge-driven mechanism underlying the E-field control of the PMA. This represents a particularly difficult problematics, especially when dealing with complex magnetic alloy materials with tunable spin polarization and Gilbert damping in epitaxial MTJ multilayer stacks where the electronic transport is controlled by Bloch symmetry filtering effects. The project concluding objective is oriented towards technological transfer targeting a new generation device: elementary cell of a non-volatile data storage matrix with low power consumption information manipulation capacity.

Abstract:
The main objective of the present project is to investigate the potential of magnetic pinning for the enhancement of the transport properties of high temperature superconducting (HTS) epitaxial films close to the critical temperature, where, due to the thermal activation, the condensation energy pinning is not effective. As HTS films the YBa2Cu3O7 (YBCO) epitaxial films will be considered due to their technological relevance in the fabrication of HTS coated conductors. Two different innovative approaches are taken into consideration in order to create nanometric magnetic pinning centers in the YBCO film: magnetic nanoparticle surface decoration using polymer based methods and YBCO/ferromagnetic core-shell nanocomposites films. It is to be noted that the proposed methods are scalable and, therefore, they could rapidly be implemented at an industrial level.

Abstract:
The project is devoted to the fabrication of thick YBa2Cu3O7 (YBCO) films with improved critical current density Jc for superconducting coatings. It is well known that Jc decreases with increasing film thickness, and our aim is to introduce combined artificial pinning centres and to grow super-lattices in a few micron thick films so that Jc to remain well above 1 MA/cm2 (at 77 K and self field). The fabrication route will involve Pulsed Laser Deposition (PLD) and chemical deposition (CSD), and the optimal conditions will be decided after the structural characterization (XRD, SEM, TEM, AFM, STM) of nanostructured thick YBCO superconducting films, correlated with a detailed investigation of the supercurrent transport properties (resistive measurements and SQUID magnetometry). The novelty of this proposal is to use a combined vortex pinning effect resulting from the presence of columnar defects, randomly distributed nanoparticles, and the substrate decoration with metal nanodots, as well as the quasi-multilayer approaches, in order to diminish the detrimental effects of various vortex excitations. The starting materials will be mainly those for YBCO with various inclusions, and different substrates, including LZO and Gd-added CeO2-buffered textured substrates (RABiTS approach), will be probed. The proposed project is multi-disciplinary one: materials science, surface science, nanotechnology, chemistry, condensed matter physics, applied and superconductivity and magnetism. A special care will be devoted to the changes in the vortex dynamics (dissipation processes) appearing with the modification of the complex film microstructure, which necessitates a better understanding of the effects of many vortex excitations and vortex creep regimes appearing in this situation: half vortex loops, double vortex kinks, super-kinks, variable range vortex hopping, plastic and elastic vortex creep.

Abstract:
Diluted magnetic oxides (DMO) are expected to play an important role in interdisciplinary materials science and future electronics because charge and spin degree of freedom coexist into single material. The control of the high temperature ferromagnetism and of the spin and charge transport in DMO micro- and nanostructures represent a necessary condition for the achievement and miniaturization of spintronic devices which could operate at and above the ambient temperature. The project involves a competitive and complementary partnership between 2 Technical Universities and 4 National R&D Institutes and has the main goal to obtain top research results based on the experimental and theoretical researches which will be performed on micro- and nanostructured semiconducting ferromagnetic oxide systems synthesized by innovating methods. By means of that, it will be answered to the still controversial problems in the fundamental research referring to the effects induced by the low dimensionality, magnetic ions doping degree and by the synthesis methods on the propitious characteristics necessarily to get the high temperature ferromagnetism in II-VI oxide semiconductors.

Abstract:
The purpose of the project consists in the development material models at microscopic scale and their transfer to macroscopic scale by implementation in computer programmes for the simulation of sheet metal forming processes. In order to achieve this purpose, four objectives have been defined. The first objective consists in the experimental characterization of the materials selected for testing at micro- and macro-level. By achieving this objective, a database referring to the plastic behaviour of the tested materials will be created. The second objective consists in the development of plasticity models at micro- and macro-level. By achieving this objective, the members of the consortium will have a set of realistic and robust plasticity models able to describe the anisotropic behaviour of materials. The third objective consists in the implementation of the previously developed models in computer programmes for the simulation of the sheet metal forming processes. By achieving this objective, the consortium will have a set of robust and efficient computer programmes for the numerical simulation of hydraulic bulging, deep-drawing of cylindrical parts and prediction of the forming limit curves. The last objective of the project consists in the experimental validation the simulation programmes previously elaborated. By achieving this objective, a set of simulation programmes having a high accuracy will be available for the use in industrial applications with the aim of obtaining a realistic and robust virtual prototype. The achievement of the general purpose needs the cooperation between experts from interdisciplinary domains and having a rich expertise in modelling, numerical methods, experimental procedures, with a comprehensive understanding of the phenomena that occur at micro- and macroscopic scale. With this aim in view, an interdisciplinary and complementary consortium as concerns the scientific background and the laboratory equipment has been established.
