Abstract:

Converting solar energy into clean energy, such as hydrogen energy, is admitted as one of the most effective approaches to resolve the energy problem, in this regard, photocatalysis being considered as a spearhead of such an approach. The major hurdle that needs to be overcome in this area however is the recombination of photogenerated electrons and holes. In this regard, the combination of MXenes with various semiconductor photocatalysts led to a marked increase in photoactivity. In this view, through this project, we aim to develop new photocatalytic systems that comprise the use of i-MXene-semiconductor composites for hydrogen production by photocatalytic water splitting reaction. The project approach is to develop operational powder composites based on i-MXene and stable and active semiconductor photocatalyst materials, which should be able in the end to perform easily the hydrogen evolution reaction on their surface. The originality of this project stands in the enrichment of current knowledge in the field of hydrogen evolution reaction by photocatalytic water splitting. It has to be underlined that, currently there is no studies published in the literature comprising the use i-MXene as co-catalysts for this application.

Abstract:

The project proposes a detailed study on the sensing properties of Sn1-xGdxO(4-x)/2 prepared by alternative chemical synthesis routes. The doping level varies by using the appropriate amount of Gd precursor solution, with nominal concentrations ranging from 0 to 100 at. %. The obtained pure and doped nanostructured powders will be subject of extensive investigations regarding the crystal phase homogeneity, chemical composition, grain size distribution, relative spatial distribution of the component oxide phases, materials purity, specific surface area and pore size distribution, quantitative evaluation of the concentration of Gd3+ ions in the samples, determination of the annealing induced changes in the defects population and Gd oxidation state, identification of the defects potentially involved in the sensing mechanism. The sensors obtained by powder deposition onto commercial substrates will be evaluated under in-field conditions ensured by a fully computer-controlled Gas Mixing System. In addition to the operating temperature, the effect of Relative Humidity and CO2 concentration on the sensor signal will be sample selection criteria. Selectivity assessment will complete the sensing properties evaluation. Simultaneous measurements of DC electrical resistance and Contact Potential Difference will reveal the phenomenological behaviour associated with both surface band-bending and electron affinity, allowing to propose a chemo-resistive sensing mechanism for CO2.

Abstract:

The project exploits recent and promising results of the proposing team in developing L10 phase in Mn-containing binary alloys such as MnAl and derivatives of this system with good hard magnetic performances.

The project general objective is to develop high performance, lightweight, nanocomposite magnets having L10 phase systems with less costly elements, conceived by an innovative combination of non-equilibrium techniques, and to derive by additive manufacturing a proof-of-concept demonstrator with specific shapes and performance similar to those of RE containing hard magnets, validated in laboratory conditions, for renewable energy applications and energy storage applications.

The second project objective, is to demonstrate the applicability of magnets developed in the project by creating a magnetic bearing for a flywheel energy storage system, testing its performance and validating them in laboratory conditions, simulating real conditions of operation and thus bringing the level of developed demonstrator to a TRL level of 4.

Abstract:

The project’s scope is to obtain and demonstrate RE-free magnets with less costly elements, based on systems with L10 phase, which can be used in extreme operating conditions. Compared with the existing magnets on the market, the new magnets obtained by the industrial implementation of the project outcomes are made of less expensive metals (Mn, Al, Ni, Fe etc.), all largely available. Within the project, a proof-of-concept using RE-free magnets in implants for dental prosthesis fixation will be developed. The lower costs of the implants resulting from the project development will make these products accessible to more elderly and underprivileged patients. Novel technologies for dental implants, easier to use, stronger and less costly, have strong perspectives to penetrate the markets. Therefore the development of the RE-free magnets and dental implants as proof-of-concept, proposed by this project, is both stringent and opportune. The applicability of the newly developed magnets will be demonstrated by manufacturing a demonstrator implant with magnetic abutments.

The objectives are: a) RE-free magnets derived from systems with L10 phases, low-cost and corrosion resistant and with magnetic performance close to those of classic permanent magnets; b) prototype dental implant with magnetic abutments and retainer for dental prosthesis fixation. The technologies for magnets development through modelling, synthesis, characterization and testing, as well as for manufacturing the implants will be validated at laboratory scale.

Abstract:

Electric-field control of magnetism has remained a major challenge which would greatly impact especially data storage technology, but also other types of logic and electromagnetically controlled devices. Control of magnetic properties by an electric field would enable new data storage technologies operating at low electrical power. Although the electric field could be used to manipulate a wide range of magnetic properties, e.g. Curie temperature, magnetic moment, coercivity, and magnetic anisotropy, the realization of 180° magnetization switching could only be realized in few systems. The scope of this project is to obtain and validate an advanced material, namely a rare earth garnet of RE3Fe5O12 type (RIG), with RE=Tb, Gd, Dy and Ho for future generations of electronic devices. The project’s general objective is to select a material (demonstration model) with suitable magnetic properties for high performance spintronic applications, namely a magnetic switching device. The proposed material will be obtained by our original technological route that combines a cheap and facile surfactant assisted hydrothermal method to prepare mesoporous RE3Fe5O12 structures followed by Spark Plasma Sintering (SPS) and post-annealing to consolidate the obtained nanoparticle powders into high-density nano structured bulks with controlled and refined properties. The challenge of this project is to select a material in which we could achieve a fast and robust switching of magnetization under low current excitation near room temperature. For comparison, materials obtained by the classical method (solid state reaction) will also be assessed.

Abstract:

Nowadays flexible optoelectronic devices have a significant impact in many areas of research. Particularly, in the last years, flexible light emitting diodes (LEDs) focused the attention of the researchers, representing an energy efficient lighting technology due to their substantial role in reducing the global energy consumption, making them the perfect candidates for street lighting in Smart Cities. Compared to the conventional light sources, flexible LEDs present a series of advantages, like flexibility, lumen efficiency, low power consumption, long life time, controllable emission properties and the possibility to use wavelengths from ultraviolet to infrared. Such features recommend LED’s for applications in rollable displays, wearable intelligent electronics, light sources, sensors, optical fibers, digital displays, traffic lights, communications, medical treatments, etc. Thus, LED devices have become very important from scientific and socio-economic point of view. In this context, the scope of the project is the development proof-of-concept energy efficient flexible light emitting diodes with low power consumption and improved light extraction efficiency, the LEDs being based on vertically aligned coaxial ZnO-ZnSe heterojunction nanowires arrays and on single coaxial ZnO-ZnSe heterojunction nanowires. The coaxial ZnO-ZnSe heterojunction nanowire arrays will be prepared using Zn foils and Si/SiO2 wafers patterned with specific geometries as substrates, combining thermal oxidation in air with RF magnetron sputtering, two simple and low cost techniques. Fabricating flexible and nanoscale LEDs based on coaxial ZnO-ZnSe nanowires, will provide new insights in the field of light emitting diodes, expanding the possibilities for their implementation in applications such as rollable displays, street lighting and wearable intelligent electronics, energy efficient devices.

Abstract:

Enhancing the Specific Absorption Rate (SAR) of magnetic structures is essential for the development of promising hyperthermia-based cancer therapies with magnetic nanoparticles (MNPs), currently still under clinical trials. Depending on the involved heat transfer mechanism, superparamagnetic relaxation time as well as the coercivity of MNPs can be conveniently used for SAR tuning.

Up today, it has been demonstrated that the two parameters do not depend only on the type of MNP but are affected also by inter-particle interactions (theoretical framework developed by the proposer).

The present project aims to find new ways for tuning SAR, via the above mentioned parameters, by a suitable long-range organization of magnetite MNPs (e.g. MNPs grouped in circles, ellipsoids, spheres, rectangles etc). It is estimated that successful implementation of the project will boost the future development of hyperthermia-based cancer treatments. Moreover, computational methods and experimental methodology developed during the project will be essential in any field involving morphological characterization of nanoparticles.

Abstract:

The energy consumed to maintain thermal comfort inside buildings is a significant percentage of the total energy used reaching 20-40 % in the developed countries. This amount accounted for 10% of the global energy used in 2010. Consequently, building energy has a major impact on the energy-related carbon dioxide (CO2) emissions. According to the Kyoto protocol in 1997 and the Doha Amendment in 2012, energy saving measures should be taken for the reduction of CO2 emissions and building energy losses. The best solution for reduction of energy losses is the so called “passive approach”. Based on this approach, the thermal performance can be increased by using building envelope techniques (e.g., thermal insulation and coated windows). In modern urban structures, glass is mainly used for the outer surface of the buildings. Glass as a material is one of the most inefficient components of buildings. Prevention or minimization of energy losses and enhancement of the thermal performance of the glass will reduce energy consumption in the building and CO2 emissions. An ideal-smart window should maintain a high visible light transmission, but it should control the infrared (IR) transmission. The control of the IR transmission and glazing characteristics are significant parameters in the building window standards for usage in smart windows. The scientific community has recently made attempts to improve the efficiency of smart windows with dynamic approaches. Thermochromic smart windows based on transition metal oxide coatings offer a very promising solution, having the ability of solar modulation and luminous transmittance.

Abstract:

Among different types of sensors, those based on semiconducting metal oxides stands out through their: robustness, selective sensitivity, low fabrication costs and infield operation (presence of the relative humidity, variable temperature, the presence of potential interfering gases, etc.).

The idea of the current project proposal consists in exploring the intrinsic nature of Nickel Oxide (NiO) as sensitive material together upon inspired chemical synthesis pathways, merging towards extracting the insights of its gas sensing performances towards different target gases (CO, CO2, NO2, CH4, NH3, SO2, H2S) adapted to work under infield conditions.

The research work employs interdisciplinary vision of the team spanning from: chemical-physics and theoretical physics.

The novelties brought by the project are:

- Structure-functioning relationships will be highlighted by understanding the role of sensing and transducing features with multi-dimensional NiO nanostructured based sensors. Through inspired chemistry synthesis, NiO morphologies will be tailored to maximize the gas sensing performances.

- The challenge is to fuse the theoretical predictions with the realistic gas sensing outputs into an overview image about the nature of gas surface interactions.

The outputs from phenomenological and catalytic investigations will guide the theoretical modeling towards extending the gas surface model of NiO sensors.

Project website: https://infim.ro/en/project/high-quality-hzo-and-aln-films-grown-by-industrially-compatible-techniques-for-next-generation-electronic-and-sensing-devices/

Abstract:

The project aims to (i) delineate the conditions for the synthesis of high-quality Aluminum Nitride (AlN) and Hafnium – Zirconium Oxide (HZO) layers onto large-area substrates by Chemical Vapor Deposition (CVD) and Atomic Layer Deposition (ALD), and to (ii) integrate them into electronic devices. These two materials (AlN and HZO) have a great potential for high-tech industry, e.g. pyroelectric sensors and next-generation field effect transistors.

Fundamental physics and applicative studies will be harmoniously intertwined for a better understanding of these topical materials characteristics and of their impact on the output parameters of the devices.

The project activities are designed to find the answers to several critical pending issues, such as the pyroelectricity and the origin of ferroelectricity in HZO and of the negative capacitance effect, or the sustainability and limits of AlN-based sensors in harsh environments. Ferroelectric memories, metal-insulator-semiconductor and thin film field effect transistors structures will be fabricated and subsequently analyzed, and the results will be interpolated and discussed with respect to the physico-chemical features of the AlN and HZO thin films.

CVD and ALD techniques are underdeveloped in Romania, even though they have demonstrated tremendous advantages and applicability potential for the development and large-scale production of nano- and micro-electronics. Thereby, the development and successful application of the CVD and ALD techniques, in the framework of this project, for the deposition of high-quality thin films, will represent an important achievement, of high-interest, at both regional and national level.

Abstract:

The main objective of the project is to obtain ferroelectric materials with controlled electronic properties at the same level as this properties are controlled in Si. This will be realized by hetero-valent doping, correlated with stress engineering and band gap engineering without affecting, as much as possible, the ferroelectric properties. The main objective is complex and ambitious because, up to date, there was no experimental demonstration that it possible to obtain n or/and p type conduction in epitaxial ferroelectrics. The successful achievement of this objective will open a new domain, that of ferroelectric electronics or ferrotronics, by producing electronic devices of p-n homo-junction type or junction transistors with ferroelectric materials. Two types of materials are envisaged, namely lead titanate-zirconate (PZT with tetragonal structure and a mixed bismuth ferrite (BFO) with bismuth chromit (BCO). In the first case the heterovalent doping will be studied on Pb or Zr/Ti sites with the aim to obtain n and p type conduction. The final goal is to produce a p-n homo-junction based on epitaxial PZT films. In the second case band gap engineering will be tested by varying the Fe/Cr content, and the dominant conduction mechanism will be identified, the goal being to use the material in photovoltaic applications. The activities will contain: theoretical studies regarding the relation between dopants, electronic properties and the ferroelectricity, including self-doping effects or electrostatic doping; target preparation for deposition of thin films; epitaxial growth of the film; characterization activities of the structure and physical properties. Not only classic doping in the target is envisaged but also doping during the epitaxial growth. The consortium is composed of 4 teams from three different institutions, including a number of 14 young researchers full time equivalent.

Abstract:

The main objective of the project “Enhanced magnetic hyperthermia for malignant melanoma therapy” (EMA-HYPERMAT) is to increase the level of TRL maturity of a technology for treatment of the malignant melanoma by means of magnetic hyperthermia, implying drug delivery nanosystems developed by us. Nanoparticles could be efficient cytostatic delivery systems, capable of tumor targeting; thereby, the use of such nanosystems decrease adverse effects, increase therapy effectiveness, and increase the survival of skin cancer patients. The combination of chemotherapeutics and hyperthermia can be adjusted, depending on the type and site of the tumor, also on the drug dose and temperature. We propose to combine the advantages of hyperthermia with the controlled delivery of the antitumoral loaded into magnetic particle systems. In this respect, the novelty of our proposal is related on the use of hyperthermia enhancers based on the combination of iron oxide/silica core-shell particles and superparamagnetic iron oxide nanoparticles (SPIONs) embedded into the thermoplastic polymeric nanospheres. Both particle systems bring specific advantages. For such formulations, smaller concentrations of the iron oxide nanoparticles are necessary in order to obtain similar performances in hyperthermia tests which results in lower toxicity, reduced immunogenicity and side effects while magnetic polymeric nanospheres will provide improved efficiency in the case of hyperthermia and a better drug release due to the higher loading capacity of the polymer matrix.

Abstract:

Plastic is an essential material in our daily lives that has multiple functions: food packaging bottles and jars, insulators, microchips in phones and computers, textile industry and so on. The world’s annual consumption of plastic materials has increased from around 5 million tonnes in the ‘50s to nearly 300 million tonnes in 2020. Due to plastic’s resistance against degradation and its increased production in industry, the issue of plastic pollution has evolved to become a menace to global ecology. Therefore, there is an urgent need to resolve these environmental issues that minimise the importance of these materials that play an important role in our daily lives. All these recycling approaches have limitations because the PET can only undergo a finite number of processing cycles before their properties are significantly compromised ends up in the landfills or is incineration, being the source of others pollutants. However, PET could be recovered through chemical recycling, we could save the natural resources and the prices of polymers would be lower. RECYCLE propose a simple solution, to heterogeneously catalyse PET depolymerisation using surface modified flexible materials, in which 2D malleable flakes/sheets are surface modified by strong acidic functionalities, like sulfonates.

(i) the parameterization of an accurate EFF of type ADP (Angular Dependent Potential) for the hydrogen-magnesium interaction, which has to be transferable from bulk (liquid, polymorphs) Mg and MgH2 to their surfaces, interfaces and nanosystems. The ADP force field has to be able to predict the shapes of the MgHx nanoparticles (with a different contents x of hydrogen) that will be identified by the experimental investigations, for different particle-sizes. The Wulff techniques will be used to construct the nanoparticles, based on the surface energies of the most faces of the Mg and MgH2 polymorphs, calculated by DFT and ADP methods,

(ii) the design of proper analysis methods for the characterization of structural, dynamic, vibration properties of the nanoparticles with different degrees of hydrogenation, as well as the hydrogen (de)sorption and diffusion into the magnesium nanoparticle during the Molecular Dynamics simulations of hydride formation and decomposition,

(iii) the including of the analysis software as an user module in the simulation code LAMMPS, which is one of most performing simulation software, designed for High Performance Computing.

(iv) the use of the parameterized force field in the frame of the project for guiding the synthesis of the pristine and confined Mg-based nano-hydrides.

Abstract:

The project is focused on strengthening of the innovation capacity and development of technologies and products by the implementation of optimized biotechnologies for obtaining structural compounds with healing effect (chitin and keratin) from entomological and skin residues and innovative multicomponent associations (plant extracts and bio- efficient intermetallic materials) with the purpose of obtaining, by 3D-printing technology ,of integrated systems for the delivery of active principles. We propose to obtain at least three prototypes (dressing / polymeric 3D matrix, with integrated active principles; film forming gel and powder), aiming skin regeneration, an essential element in the therapies for chronic skin diseases like „non-healing wounds” / „delayed healing wounds” with high incidence in population. The complex transition of the project’s technological maturity will made gradually, with different stages of initiation TRL4 / TRL5, based on experimental and technological know-how towards the validation of the multicomponents system (keratin / chitin / plant extracts / magnesium boride / 3D matrices), and proof of „in vitro”- „in vivo” intercorrelated efficacy by accelerated skin regeneration models. The innovative character is given by: the biotechnological valorification of the entomological and skin residues; associations of structural compounds / herbal extracts / intermetallic antimicrobial structures; top-of-the-line advanced topical formulations - 3D-printing for skin regeneration, with impact on personalized medicine in Romania. The concept of multifunctionality and the multidisciplinary approach to the biotechnological valorisation of entomological and skin residues opens excellent opportunities for all the partners involved in the project and promotes the implementation of new technologies in the industry in line with the integral exploitation of raw materials

Project website: http://infim.ro/project/caracterizarea-la-scala-nanometrica-a-materialelor-functionale-avansate-de-la-2d-la-3d/

Abstract:

In materials science, when designing and investigating the chemo-physical properties of new materials the sine qua non starting point is represented by the necessity to identify, understand and control the microstructure of the examined material. Nanosciences and nanotechnology require manipulating nano-objects or even individual atoms, which requires complementary spectroscopic, diffraction and imaging techniques able to provide information at nanometric scale or below. One of the major challenges today in designing and engineering nanoscale functional materials is the complex 3D characterization on a nanometric scale. Electron tomography represents the only reliable technique to provide 3D morphological, structural and analytical information at nanometric scale. In our country we are now able to perform state-of-the-art analytical microstructural investigations by HRTEM, STEM and EELS, including atomic resolution elemental mapping or direct visualization of light atomic species. Electron tomography has been only introduced and developed in the field of life sciences, being currently applied in cellular biology, while electron tomography in materials science is not yet present. The scientific motivation of this project is to open the way at the national level towards electron tomography in materials science as a new dimension in the microstructural characterization of the advanced functional materials. The project will be focused on metal oxide semiconductors (MOS) functional materials to be used as gas sensors for environmental monitoring. Along with complementary spectroscopic techniques (EELS, XPS, EPR) the project will create a complete “3D+” insight (3 spatial + 1 spectroscopic dimensions) into the fine chemo-physical processes at nanometric scale in order to reveal and understand the connection between the 3D microstructural/spectroscopic properties and the functionality of the MOS gas sensing systems.

Abstract:

In an era of shrinking conventional energy resources, the development of low-power-consumption

portable devices, sensors and body-implantable devices, the concept of generating power by harvesting

energy from the ambient environment and biomechanical movements is attracting huge interest. The most

efficient way to harvest electrical energy from mechanical movements is to utilize the piezoelectricity of

ferroelectrics. In the HarvEnPiez project, the influence of shape and size on the piezoelectricity of

ferroelectric particles will be predicted by ab-initio calculations. Different ferroelectric particles with

defined sizes and shapes of plates, cubes and/or wires will be synthesized and systematically selfassembled

on a substrate for the energy-harvesting devices. A high-performance device will be developed

based on the optimized composition, shape, size and orientation of the ferroelectric particles and/or the

enhancement of the piezoelectricity through lattice-strain engineering.

Abstract:

A complex method for the investigation of some important magnetic parameters of technological interest for magnetic recording media or concerning the magneto-conduction functionality of lateral micro-sized senzors with nanometric thickness is proposed. The considered approach, based on the suitability of the magneto-optic Kerr effect (MOKE) for the investigation of microstructured magnetic thin films, involves both the realization of a specific multifunctional magneto-optic device and the implementation of different measuring methodologies providing information on the magnetic behaviour of the micro-magnetic systems. With respect to the first issue, the practical realization and development of a demonstrative model of advanced high precision optoelectronic device for measuring complex magnetic properties in micrometer sized and nanometer thick magnetic components is envisaged. Innovative solutions in adapting new configurations for the MOKE investigation, via micro-sized focusing on vizualized magnetic micro-structures and specific sample stage with three dimensional scanning and rotational degrees will be considered. The main advantages of the proposed multifunctional vector system (TRL3 level) as compared to already existing MOKE systems will be: (i) the combination of precision, speed and reliability of local (micrometer size) measurements, (ii) the ability to be adapted to both fundamental and applied scientific research and (iii) the suitability for controlling the production process of multi-component (integrated) sensors and actuators. With respect to the second issue, different complex methodologies (TRL3 level) for obtaining as much as complete information on the hysteretic behaviour, anisotropy directions, easy axis distribution, magnetic relaxation phenomena in microstructured thin films and even on magnetic domain configuration will be proposed and implemented on the multifunctional MOKE demonstrator.

Project website: http://www.plasmacoatings.ro/?page_id=155

Abstract:

The present project proposes the development of X-ray mirrors by means of an original film deposition method, a high voltage anodic plasma, also known as Thermionic Vacuum Arc (TVA). The challenge is to enhance reflectivity (to more than 50%) at higher order of reflection (7, 9, 11) in order to increase the deflection angle of the mirror. This is obtained by increasing the number of bilayers, which technically increases the overall roughness. In order to overcome these problems, new plasma technologies which can provide higher quality nanofilms and interfaces are needed.Nanometer sized monolayers and then multilayers of alternating nano-layers of high - low atomic number (Z) elements such as W, Mo, Ta and Si, B will be obtained by deposition using TVA.

Project website: http://www.infim.ro/projects/high-energy-efficient-permanent-magnets-without-rare-earth-elements

Abstract:

This project aims at producing, characterizing and optimizing the magnetic properties of a new class of permanent magnets with high energy efficiency based on iron nitride Fe16N2 with martensite structure. Theoretical predictions for this permanent magnet indicate a maximum energy product (BH)max of up to twice the theoretically maximum allowed for the highest performance magnet up to date, namely Nd2Fe14B. The project addresses a theme that became an imperative of global research and development activities taking into account the tremendous increase of the price of rare earths. It follows a multi-disciplinary approach to the problem. Theoretical calculations based on density functional theory are used for choosing optimal doping elements (transition metals and non-metals) of Fe16N2 which show a favourable effect on increasing thermodynamic stability and also in magnetic properties improvement, i.e. increase of magnetization (via population of sublattices presenting ferrimagnetic configuration) and anisotropy. Simulations of the Fe16N2 magnetic particles embedded in matrices will allow us directing preparation methods in order to obtain magnetic particle size and morphology suitable for enhanced coercivity and high remanence magnetization. Several preparation routes will converge on the obtaining of the compound Fe16N2 and other similar. A first route of preparation uses wet chemical methods that allow obtaining Fe16N2 doped particles. Firstly, it will be obtained the iron oxide or iron oxy-hydroxide precursor with controlled morphology and size using different chemical methods in solution. Subsequently, by thermal treatments of the iron oxide or oxy-hydroxide precursors in hydrogen and ammonia atmosphere one gets Fe16N2 fine magnetic particles with needle-like or ellipsoidal shape that show an important shape anisotropy and high coercivity. The second procedure is to obtain nanocomposites based on Fe16N2 by ball milling the iron powders and doping elements under hydrogen and nitrogen/ammonia reactive atmosphere. Processing of the milled composites and Fe16N2 magnetic particles doped with transition metals and non-metals will be performed using a glove box with controlled atmosphere in order to avoid the exposure to oxygen and moisture from air. Procedures for mixing with binder, orientation in applied magnetic field, pressing and sintering for long time at temperatures below 200 0C will allow to obtain anisotropic permanent magnets based on Fe16N2 with high coercivity and remanence magnetization. The energy product of this magnet will be higher than that of cheap magnets that do not contain rare earth. The magnetic particles and final sintered magnets will by characterized by X-Ray diffraction, neutron diffraction, electron microscopy. Iron-containing phases will be analyzed by Mossbauer spectroscopy. A complex characterization of the magnetic properties (hysteresis, saturation and remanence magnetization, coercivity) will be performed. Optimization of the magnetic properties will assume a permanent feedback between preparation methods – structural / compositional characterization – magnetic properties. The magnets will be coated against corrosion. The new innovative technologies used to produce these magnets will be the subject of patent application. The main outcome of the project, after performing the project activities, will be the permanent magnet without rare earth, which has higher energy product than cheap commercial magnets. A part of the results, which are not subject to patenting, will be disseminated through ISI publications and communications at international conferences.

Antireflection coatings for ultra-short high power lasers Call name: Joint Applied Research Projects - PCCA 2013 - call

Abstract:

The ARCOLAS project addresses an important topic fitted with specific thematic area of New Photonic Materials, namely design and testing as demonstrator of durable advanced antireflection (AR) coatings for plasma mirrors working in ultra-short TW/PW lasers systems.

It is intimate related to the existing high level technological ultra-short pulses lasers network facility in NILPRP (CO) and, with the aim and goal to upscale the obtained optical components for the unique ELI-NP facility to be built in the Magurele research area and where NILPRP is involved as partner.

The project answers to the demand for optical components used to ultra-short high power lasers systems because the number of these facilities is increasing and there are only two suppliers in the world.

The project will be developed in precise steps, following the concept in its theoretical and practical aspects.

First, the composition/combination of the dielectric materials with different refractive indices to be used as thin film(s) and/or heterostructures with antireflection properties will be studied.

The different layers will be obtained by pulsed laser deposition (PLD) and PLD assisted by a Radio-Frequency discharge (RF-PLD).

The experimental parameters for obtaining of each layer and of layers combination will be established after their careful characterization by specific techniques as AFM, XRD, spectroellipsometry, SIMS, SEM, HR-TEM, with high performance equipments belonging to the involved partners.

Then, optical components – demonstrators with controlled antireflection characteristics will be obtained based on dielectric layers with optimized properties and deposition architecture with the objective to be compatible with generation of plasma mirrors capable to withstand high energies ultra-short laser pulses.

Simultaneously, computer simulation studies regarding the phenomena that rise when a high energy ultra-short laser beam hits a material will be performed using Particle in Cell-Finite Difference Time Domain method.

Of a paramount importance in the project will be the components-demonstrator for plasma mirror testing in ultra-short high intensity laser field, in relativistic regime (intensities of 1018 W/cm2 - 1020 W/cm2). This will be made at INFLPR, where there is already established a complete and unique power-chain laser system: GIWALAS – GW, TEWALAS – TW and CETAL – 1 PW. The possibility of the direct access to these facilities will allow a rapid feedback regarding the AR coating behavior in the plasma mirror regime.

An important aspect is related to the prospective to use the demonstrator for the future 10 PW ELI-NP facility, where ultra-relativistic regime (1023 - 1024 W/cm2) are expected to be generated.

The industrial partner has the ability to design and produce the supports for optical components capable of withstanding high power ultra-short laser pulses.

The generated results will be the subject of patents first, as the topic is of vanguard, and of publications in high impact journal.

Project website: http://www.infim.ro/projects/atomically-resolved-structure-and-interface-related-phenomena-nano-scale-modulated-smart

Abstract:

Physical properties of advanced materials like artificial multiferroics, multilayered structures of semiconductors, shape memory alloys (SMA) result from the interaction between the micro- or nano-scale components (crystal grains, thin films), involving interface processes. The importance of the interface phenomena and of the associated structural defects increases with the size reduction of the involved crystal grains or thin layers. Getting accurate structural information at and near the interface between the nanoscaled components (atomic structure of the interface, associated extended defects, strain fields) becomes mandatory in understanding and designing the physical properties of new materials. Advanced techniques of analytical electron microscopy along with consecrated structural and thermal analysis techniques using state-of-the-art equipments will be mainly employed for thorough microstructural investigations on two classes of materials for which interface phenomena play a crucial role: i. artificial multiferroics and ii. shape memory alloys.

The project specific objectives are:

1. Atomic structure of interfaces and structural defects in artificial multiferroics.

2. Strain field and composition mapping at atomic scale around interfaces and structural defects in artificial multiferroics.

3. Correlation between structural phase transitions and strain fields in nanoscale modulated SMAs.

4. Atomically resolved crystal structure in nanoscale modulated SMAs.

Abstract:

The project refers to the microstructural transformations induced on thin films by pulsed laser irradiation at low fluences, lower than the ablation threshold. At microscopic scale, the laser irradiation actions shows some new features which are related to the laser wavelength, especially in the case of coherent laser radiation. The project work is focused on the photomechanical effect of the coherent laser beam on the structure of densified amorphous sol-gel oxide films, on structural phase modifications in mixed thin films and on the behavior of the melted metallic films and microsphere formation under the action of high power laser pulses.The structural studies are performed by conventional and high resolution transmission electron microscopy (TEM), atomic force microscopy (AFM), electron and X ray diffraction.
