Interfacial superconductivity in AIVBVI semiconductor heterostructures

Dr. O. Yuzephovich, Department of Materials and Ceramic Engineering, University of Aveiro, Aveiro, Portugal (November/30th, 2016).

Dr. Olga Yuzephovich, Senior Researcher of the Department of Superconducting and Mesoscopic Structures from the B. Verkin Institute for Low Temperature Physics and Engineering of NASU, (Kharkov, Ukraine) presented a review of the integrated study of interfacial superconductivity in the PbTe/PbS, PbTe/PbSe, and PbTe/YbS heterostructures. Superconductivity of these heterostructures is an unusual property because the individual AIVBVI layers are not superconductors. Superconductivity is associated with periodic grid of the misfit dislocations formed at the layers interface.
Both the dimensionality and the period of these superconducting nanostructures can be changed by the variation of the type of semiconductors, the thickness of layers, and their number. Recent investigations suggest a magnetic field induced superconductor-insulator transition.

Advanced neutron diffraction for functional materials

Dr. Pascal Manuel, Department of Materials and Ceramic Engineering, University of Aveiro, Aveiro, Portugal (March/30th, 2016).

Dr. Pascal Manuel, Instrument Scientist from STFC-ISIS – Pulsed Neutron and Muon Facility, Rutherford Appleton Laboratory (Didcot, UK) gave a lecture entitled “Advanced neutron diffraction for functional materials”. In this lecture, he reviewed some recent developments in neutron instrumentation and sample environment which have enabled cutting edge experiments to be performed on functional materials.
After a brief introduction on what makes neutrons unique for studying materials, he proceeded to explain how new instrumentation now routinely allows magnetic structure determination from small powder samples made by high pressure synthesis and even from sub-100nm thick thin films. New developments in high magnetic fields and high pressure cells were also illustrated by the recent neutron diffraction studies of multiferroics.

Sol-gel process for oxide materials

Prof. Aldona Beganskiene, Institute of Solid State and Semiconductors Physics of the Scientific-Practical Materials Research Centre, Minsk, Belarus (February/24th, 2016).

Prof. Aldona Beganskiene and Dr. Andrius Stanulis from the Sol-gel Group of the Inorganic Chemistry Department of Vilnius University (Lithuania) visited the Institute of Solid State and Semiconductors Physics of the Scientific-Practical Materials Research Centre (Minsk, Belarus) within the framework of the TUMOCS project. The research of Prof. A. Beganskiene is focused on sol-gel process for oxide materials. In her talk entitled “Sol-gel process for oxide materials“, she presented the main concept of sol-gel method, advantages and application for synthesis of oxide nanopowders and other nanomaterials. The sol-gel process is a wet-chemical technique widely used in the fields of materials science and ceramic engineering. Sol-gel synthesis methods are used primarily for the fabrication of materials (typically a metal oxide) starting from a chemical solution which acts as the precursor for an integrated network (as gel) of either discrete particles or network polymers. Sol-get techniques have become very popular recently due to their high chemical homogeneity, low processing temperatures, and the possibility of controlling the size and morphology of particles. The samples of sol-gel methods have been developed by the Sol-gel Group for oxides materials (different garnet structures and doped with lanthanides) and nanomaterials were also presented.

Review meeting of the project

University of Aveiro, Aveiro, Portugal (February/23rd, 2016).

As it has been stated at the Grant Agreement preparation stage, the Review Meeting between the beneficiaries, the partner organisations and the Research Executive Agency (REA) of the European Commission was organised in 14th month of the project. Delegates of the TUMOCS teams from all the participating organisations, representatives of administration of the Department of Materials and Ceramic Engineering and the Research Support Office of UAVR, as well as the REA Project Officers met in Aveiro on 23rd of February: 25 participants in all. The Project Coordinator overviewed the project. He presented the general idea, objectives, scientific approaches and the expected results. The 1st-year project results which concern the technical Work Packages (WP1-4) and WP7 – Exchange, Dissemination, Exploitation and Public Engagement were presented by the teams responsible for these activities. The 2016 secondments timetables were discussed and the necessary corrections were approved. The networking/dissemination activities that are to be organised by the TUMOCS teams from VU, SPMRC and UAVR were announced. The Project Officers used the opportunity to talk with the seconded researchers to ensure that the secondments are arranged and paid in accordance with regulations of the H2020 MSCA-RISE programme and to answer any personal questions. In her feedback at the end of the Meeting, the Project Officer of TUMOCS acknowledged that the project is performed successfully.

ISIS neutron scattering facility

Dr. Oleg Kirichek, Kharkov Institute of Physics and Technology, Kharkov, Ukraine (December/23th, 2015).

Dr. Oleg Kirichek, head of the Sample Environment group of the ISIS facility, visited the Kharkov Institute of Physics and Technology (Ukraine) within the framework of the TUMOCS project. In his talk, aiming to provide an overview of the facility and to make an introduction into the neutron scattering technique, Dr Kirichek underlined the main principles of excessing the facility and the key aspects of the neutron science. The ISIS pulsed neutron source at the Rutherford Appleton Laboratory in Oxfordshire is a world-leading centre for research in the physical and life sciences. ISIS produces beams of neutrons that allow scientists to study materials at the atomic level using a suite of instruments, often described as ‘super-microscopes’. It supports a national and international community of more than 3000 scientists who use neutrons for research in physics, chemistry, materials science, geology, engineering and biology. Neutron scattering is a unique technique for exploring the structure and dynamics of materials at the nanoscale. The process of neutron scattering is non-destructive and produces results that cannot be achieved by other techniques. Neutrons are used to study the dynamics of chemical reactions at interfaces for chemical and biochemical engineering, food sciences, drug synthesis and molecular biology. Neutrons can probe deep into solid objects such as turbine blades, gas pipelines and welds to give a unique microscopic insight into the strains and stresses that affect the operational lifetimes of these crucial engineering components. Neutron studies of nano-particles, low-dimensional systems and magnetism impact upon next generation computer and IT technology, data storage, sensors and superconducting materials.

LDH based active protection coatings

Dr. Maria Serdechnova, Institute of Solid State and Semiconductors Physics of the Scientific-Practical Materials Research Centre Minsk, Belarus (December/18th, 2015).

The research interests of Dr. Serdechnova are focused on synthesis and functional characterization of LDH based nanocontainers, used for active “smart” anti-corrosion protection. In her talk entitled “LDH based active protective coatings” she demonstrated the recent achievements in the LDH synthesis and application for corrosion protection both in form of powder and films grown directly on the surface of active material. New trends of LDH use (like magnetic properties for specific distribution of LDH in the most corrosion-risked zones) were also presented.

Applications of High-Pressure Methods to the Materials Development and Production

Dr. Oleg Ignatenko, Department of Materials and Ceramic Engineering, University of Aveiro, Aveiro, Portugal (October/21st, 2015).

Dr. Oleg Ignatenko, Deputy Director and Head of the Laboratory of High Pressure Physics and Superhard Materials of the Scientific and Practical Material Research Centre of the National Academy of Sciences of Belarus presented a review of the high-pressure techniques that are used in production of materials with unique properties. In particular, high-pressure synthesis is applied in preparation of metastable perovskites – multiferroics that are under study in the TUMOCS project. An impact of high pressure on states and properties of materials was demonstrated by example of structure transformations that occur in the Earth crust and mantle. Transformation of graphite to diamond in kimberlite pipes at a pressure that is 4-5 orders of magnitude higher than the atmospheric pressure is the most known. Diamonds and other superhard materials can be produced in laboratory conditions. Dr. Ignatenko presented the experimental techniques, which are used in the high-pressure syntheses, and compare their advantage and drawbacks. Progress of the Laboratory of High Pressure Physics and Superhard Materials in preparation of materials for productions of machining tools, jewellery and electronic components was shown.

UAVR team in the TUMOCS project: TUneable Multiferroics based on oxygen OCtahedral Structures

Dr. Andrei Salak, Institute of Technical Acoustics Vitebsk, Belarus (October/14th, 2015)

Prof. Mário Ferreira, Dr. João Tedim and Dr. Andrei Salak from the Department of Materials and Ceramic Engineering (DEMaC) of the University of Aveiro visited the Institute of Technical Acoustics (ITA) of the Scientific and Practical Materials Research Centre of NAS of Belarus in Vitebsk on 14th-15th of October, 2015. Director of the Institute, Prof. Vasili Rubanik introduced the quests to the research staff and demonstrated the equipment and other facilities. At the meeting with the ITA researchers, Dr. Andrei Salak presented the objectives and structure of the project TUMOCS with links to the MSCA-RISE programme. Research facilities of DEMaC and the project results obtained by the UAVR team using those facilities were presented as well. Role of the ITA team in the project and expected results of the collaboration were discussed. The ITA team contributes mainly to sample preparation: they apply a high-power sonication to accelerate the anion-exchange processes in layered double hydroxides. Besides, the sonication is used for mechanoactivation of the powder precursors in order to make lower the high-pressure sintering temperature and obtain more homogeneous and dense ceramics. Participation of the ITA team in TUMOCS has a good potential for extension. In frame of the project, secondments of ESRs and young ERs from ITA to UAR in 2016 were prescheduled.
