Partner 1: INCEMC - Timisoara

The National Institute for Research and Development in Electrochemistry and Condensed Matter Timisoara, founded in 1987, is a internationally recognised laboratory, historically being the first Romanian team which obtained high quality single crystals of α-SiO2 in extreme hydrothermal conditions, at high temperatures (450°C) and pressure (2500 atm). This Joint Research Project will be developed in Analyze and Characterization and Applied Physics Departments, in collaboration with scientific and technical staff involved over the years in several national and international projects with main interests in the study of materials for applications in energy, environment, information and communications, health, space and security, sensors and actuators etc.

The group research activities concern the synthesis of bulk, micro and nano-structured materials by classical methods but also by new alternative methods, designed and developed in the laboratory taking in consideration the need for high quality homogenous compounds, but in the same time reduced cost energy necessary for industrialization. As a result, more than 150 scientific papers have been published and communicated, 5 patents have been granted and 10 patents are pending. The work was also rewarded with gold medals at international invention exhibitions and fairs in Geneva, Brussels, Moscow, Warsaw and Zagreb.

The Romanian research members have high expertise in the synthesis and structural characterization, necessary capability for the study of complex properties of Fe-based CO systems. This project in collaboration with the French teams will allow the Romanian researchers to acquire new experience in physical characterization techniques (in function of temperature and pressure) and most of all will facilitate their access to Large Scale Neutron and X-Ray facilities, actually not well established for the Romanian laboratory.

Partner 2: CRISMAT – Caen

The CRISMAT laboratory (CRIStallography and MATerial Sciences) is a mixed research unit (UMR) affiliated to CNRS and ENSICAEN. Its secondary affiliation is the Basse-Normandie-Caen University (UCBN). At the CNRS, CRISMAT depends mainly on the National Institute of Chemistry (80%) and secondarily on the National Institute of Physics (20%). The permanent staff (58% of the 126 researchers working in the laboratory) are solid state Chemists and Physicists.

The research at CRISMAT aims at contributing to technological innovation by combining fundamental and applied research. This activity is devoted to synthesis, structural and physical characterization of new materials - mainly oxides -, to their optimization and modelization, the ultimate goal being to generate new functionalities for applications. This is mainly a multi-disciplinary research based on a multi-scale approach – from atomic to macroscopic – to design new materials and to understand their structure and physics.

The researchers involved in this project belong to the “New Materials”, “Crystallography” and “Physics” thematic groups of CRISMAT. They are competent in synthesis (solid state, hydrothermal) and structural studies (powder and single-crystal X-Ray diffraction - laboratory and synchrotron -, neutron diffraction, transmission electron microscopy) of oxides - including phosphates - and also in the physical characterization such as magnetism and electrical transport. Their results are extensively published in high impact journals and presented in international conferences. They have experience in international collaboration and in the supervision of PhD students.

Partner 3: ICG Montpellier- Research Group "Chemistry and Crystal chemistry" (C2M)

The Institut Charles Gerhardt Montpellier has a strong specialty in materials science with over 200 permanent researchers and technical staff and up to 100 post-docs and PhD students. The work will be performed by the research group "Chemistry and Crystal chemistry" (C2M) with Jérôme Rouquette, Julien Haines, Olivier Cambon and Philippe Papet.

This group is particularly interested in: oxides (ferroelectrics, oxide conductors, Negative Thermal Expansion materials) and the stability of functional materials at high temperature and high pressure. These investigations can either be made at the laboratory using powder/single crystal characterization techniques as a function of Temperature and Pressure or in large scale high-pressure facilities (ESRF, ILL, LLB, SOLEIL, ISIS,...). The group research activities are published by many reports in high impact reviews (PRL, PNAS, JACS, Angewandte...) or invited conferences.

The group members involved have studied classical ferroelectrics under high pressure and this project will be a very good opportunity to acquire and develop new knowledge on multiferroic complex systems, systems with two or three ferroic orders: ferroelectricity, magnetism and ferroelasticity. The high expertise of this partner in structural phase transitions under high pressure of classical ferroelectrics is of great importance for the proposed project.

PostDoc

Romanian Principal Investigator Dr Maria Poienar - INCEMC Timisoara

The Principal Investigator from Romania, Maria Poienar, is a young researcher, currently Post Doc associate at ICG Montpellier in C2M research group (2011- present). She prepared her PhD thesis in Crismat laboratory (oct. 2007 - sept. 2010), where she focused on strong lattice-spin-charge coupling in frustrated systems with layered crystal structures, mainly in multiferroics CuCrO2 and CuMnO2. During the period 01.03.2006 - 01.08.2007, she worked asResearch Assistant at INCEMC Timisoara, Romania where she started her research and training activities in the ferrofluids field and she specialised in atomic force microscopy (AFM).

Her research activities consist in combining different approaches in order to understand the underlying physics and chemistry of complex functional materials. Her work consists in the synthesis of polycrystalline and single crystals samples by different methods and also in structural, magnetic and electric characterisations by using the lab techniques or modern large scale facilities experiments. She has published 10 papers on the topic of interest and she has also given talks on the subject at international conferences, as for instance at the international Gordon Research Conference with the topic “New Frontiers In Materials Synthesis And Characterization” Magdalen College, Oxford, United Kingdom, 2009.

French Principal Investigator Dr Anne Guesdon - CRISMAT Caen

The French coordinator, Anne Guesdon, belong to the “New Materials” group at the CRISMAT laboratory. She is an assistant professor at the University of Caen Basse-Normandie (UCBN), where she teaches Inorganic Chemistry and Materials Science to Licence and Master students and has several teaching and administrative responsibilities. She is qualified for professor position from 2006.

Her research topics of interest concern the synthesis (solid state and hydrothermal), the structure determination and refinement (X-Ray diffraction, powder and singlecrystals), and the physical characterizations (electric and magnetic properties, ionic conductivity, catalytic properties) of phosphates. She has published more than 50 papers in the area and has given several talks on the subject in international conferences. She has co-supervised 2 PhD students and supervised 4 master students, 2 PhD students and 1 post-doctoral scientist. She was referee for 3 PhD thesis and member of one HDR jury (accreditation to supervise research).

Historic of the project

Principal Investigator (PI) from Romania, M. Poienar, prepared her PhD (oct. 2007- sept. 2010) at CRISMAT, under the supervision of C. Martin. Her thesis was dedicated to the synthesis, structural characterization and physical properties of type-II multiferroïcs: CuCrO2 and CuMnO2. J. Rouquette proposed her a postdoc fellowship and, from January 2011 (up to July 2012), she studied lutetium ferrite under pressure at ICGM. This joint research project will allow her to start her own activity in Timisoara at her return to INCEMC in autumn 2012. It involves her Romanian colleagues and French researchers from the two laboratories she is familiar with and has been jointly prepared, considering the expertise and specificities of the researchers involved as shown by the participation in the contracts described below.

The ANR-07-BLAN0258 (2008-2012) from the ICGM - O. Cambon and J. Haines (participants in this project) – dealt with the synthesis by hydrothermal method and characterisation of piezoelectric crystals of FePO4 and GaAsO4. The ANR-08-BLAN-005-01 (2009-2012) conducted by C. Martin (involved in this project) from CRISMAT had as objectives the synthesis of transition metal oxides and the determination of the relationships between their structures and their physical properties. Iron oxides were included in the compounds under study, such as LuFe2O4, which was the subject of the grant JC08-331297(2009-2011) conducted by J. Rouquette (participant in this project) from the ICGM. To be more precise, it was devoted to the pressure effect on the charge ordered multiferroic LuFe2O4. The experience acquired during these last three years allowed the researchers from Caen and Montpellier to get high expertise in the charge ordered multiferroic research area (concretized by two papers [8,9]) and in the same time to put the basis for further future collaborations.
