Germany / Max-Planck-Institut for Plasmaphysics (IPP)

ASDEX Upgrade is a large experimental device for exploring the concept of magnetic confinement of a high temperature plasma. It is a divertor tokamak of medium size with a fusion reactor relevant cross-section, which is an essential prerequisite for its relevance to the preparation of a future fusion reactor like DEMO. The first wall of ASDEX Upgrade is fully covered with tungsten, a reactor relevant material. ASDEX Upgrade is equipped with a versatile heating and current drive system, including all three day-one systems foreseen for ITER. It has a relatively large total power installed (30 MW, in total) realising ITER relevant power fluxes to the divertor. ASDEX Upgrade also has a large set of diagnostics allowing physics studies with high temporal and spatial resolution. Thus, the aim of the ASDEX Upgrade programme is to prepare the physics base for ITER and DEMO. ASDEX Upgrade is Germany?s largest fusion device and one of the leading fusion experiments worldwide. It is operated by the Max Planck Institute for Plasma Physics (IPP) in Garching (close to Munich, Germany) since 1991. The IPP is associated with the European Fusion Programme and the Helmholtz Association of German Research Centres.

In July 2005 the activities of the project ZECOMIX (Zero Emission Coal Mixed Technology) started officially, within the framework of a program funded by the Italian University and Research Ministry. The main aim of the project is to demonstrate, via a series of modelling and experimental activities, the feasibility of an innovative new process for the production of electricity and hydrogen zero emission by coal. Several processes such as coal gasification, clean-up of syngas, CO2 capture by means of solid sorbent (Calcium Looping, CaL) and combustion of hydrogen in gas turbines are being investigated in the ZECOMIX platform. The main objective is the production of low carbon energy from fossil fuels (coal or methane). Among the various technologies for separating CO2 from gas streams, the Calcium Looping (CaL) option, e.g. with CaO-based solid sorbents, has been receiving increasing attention. One of the key advantages of this option, which makes it a valuable route in gas decarbonisation, is the low cost and wide availability of the starting material (naturally occurring sorbent such as limestone or dolomite) and its high reactivity when it reacts with CO2. Moreover the CaO based solid sorbents are more environmentally benign compared to other state-of-the-art solutions (e.g. amine-based liquid solvents). In this technology, CaO is converted into CaCO3 during the CO2 uptake, the spent solid sorbent is subsequently regenerated by releasing CO2 in a calcination step at temperature ranges of 850 to 900 °C.

The role of BIOENERGY Research Infrastructure is to build and support sustainable development through research and innovation in the field of Bioenergy/Biomass/Biofuels in the context of knowledge-based economy. The specific aim of BIOENERGY is to provide access to high-level experimental facilities and services, encouraging and facilitating cooperative research. BIOENERGY promotes a climate of research & innovation, entrepreneurship and stimulates cooperation between business and research in order to exploit research results. Through BIOENERGY, specialists from research institutes, academia and SMEs have access to a remarkable endowment corresponding to the multidisciplinary character of research design, specific to working teams, allowing for a holistic approach, from the research phase to technology transfer. BIOENERGY represents real support for Romanian and European researchers aiming to increase scientific performance through national and international competition, because research and development in the area of biofuels, installation and technologies that meet environmental standards are now indispensible. One important attribute of the BIOENERGY Research Infrastructure is represented by the strong interaction between chemists, engineers and physicists which ensures an integrated approach to studying the complex problems related to bioenergy.

We report the synthesis of carbon nanotube (CNT) forests with a narrow diameter distribution based on Fe ion implantation method. By annealing the Fe-implanted SiO2/Si wafer in an Ar atmosphere at 800°C for 15 min, the Fe particles on the surface of SiO2 layer are successfully formed by the diffusion of Fe atoms from the SiO2 layer. Interestingly, the size distribution of Fe catalyst particles for Fe-implanted SiO2/Si wafers does not change with the prolonged annealing durations of up to 12 h. Using secondary ion mass spectroscopy and transmission electron microscopy (TEM), we confirmed that the implanted Fe atoms diffuse out of the SiO2 layer and form Fe particles on both the SiO2 surface and the interface between SiO2 and Si. The cross-sectional TEM images indicate that the Fe catalyst particles are anchored in the SiO2 layer, which limits the particles' mobility and results in an invariant catalyst size distribution for prolonged annealing durations. Therefore, we anticipate that implantation can be an efficient alternative catalyst preparation method for CNT forest growth which can solve various growth issues that are inherently caused by conventional physical vapor deposition method.

Few-layer black phosphorus (BP) is the most promising material among the two-dimensional materials due to its layered structure and the excellent semiconductor properties. Currently, thin BP atomic layers are obtained mostly by mechanical exfoliation of bulk BP, which limits applications in thin-film based electronics due to a scaling process. Here we report highly crystalline few-layer black phosphorus thin films produced by liquid exfoliation. We demonstrate that the liquid-exfoliated BP forms a triangular crystalline structure on SiO2/Si (001) and amorphous carbon. The highly crystalline BP layers are faceted with a preferred orientation of the (010) plane on the sharp edge, which is an energetically most favorable facet according to the density functional theory calculations. Our results can be useful in understanding the triangular BP structure for large-area applications in electronic devices using twodimensional materials. The sensitivity and selectivity of liquid-exfoliated BP to gas vapor demonstrate great potential for practical applications as sensors.

Helium ion-irradiation effects on the nuclear graphite tiles were studied in order to understand the structural modifications and damages that can be produced by fusion reaction in tokamaks. The surface morphological changes due to increasing dose of the irradiation were examined by the field-effect scanning electron microscopy, and X-ray photoelectron spectroscopy elucidated the changes in the shallow surface bonding configurations caused by the energetic irradiation. Raman spectroscopy revealed the structural defects and diamond-like carbon sites that increased with increasing irradiation dose, and the average inter-defect distance was found from the Raman peak intensities as a function of the irradiation dose.
