Portugal / University of Lisbon

The recently installed Stable Isotope Laboratory (SIL) of the Department of Geology at the University of Lisbon (GeoFCUL) was designed to serve the research needs of Earth and Environmental studies. This new facility is about to be inaugurated. The stable isotope laboratory is part of the "GEOLABS, Geosciences Laboratory Cluster” located at the Faculty of Sciences of the University of Lisbon, and runs under the supervision of the Research Units CeGUL and CREMINER-LARSyS.It will provide accurate analytical results for:oxygen, carbon, hydrogen and nitrogen isotopes and/or elemental analysis in water, minerals, soils and rocks. These data represent a major value both in technical and research approaches, with particular emphasis on those focused on understanding the interactions between the major reservoirs of the atmosphere, hydrosphere and lithosphere and its environmental implications, such as:1) pollution sources (soil contamination by mining and landfills. water resources),2) metallogenesis problems (signatures of hydrothermal alteration: metallic mining resources), 3) identification of fluids of different origins, 4) climatic studies (chataracterization of palaeoenvironmental. CO2 resources and flow analysis of carbon dioxide and its climatic consequences),5) identification of mixing processes, 6) identification of salinization ( intrusion recent/ancient or dissolution of evaporites: water-rock interaction), 7) definition of preferencial recharge areas,just to name a few examples.SIL constitutes the first Portuguese laboratory devoted to the analysis of O, H and C isotopes in geological materials. A laser fluorination line, able to produce O isotope data out of very small samples of silicate and oxide minerals (<100 μm) is planned to be fully installed in a short time. The SIL is equipped with an IRMS spectrometer operating in DI- or in CF- modes and is hyphenated with an Isocarb and a Multiflow for analysis of carbonate minerals and/or rocks and O and H in waters, providing C, O, H data with high levels of analytical precision. Isocarb and Multiflow use very small samples <100 μg and have suitable precision for foraminifera analysis. A pioneering system for monitoring the temperature during the phosphoric acid etching of carbonate mineral mixtures allows sequential semi-automatic extraction of carbon from the different carbonate phases. SIL includes also an elemental analyser (EA) and gas chromatograph (GC). The new stable isotope laboratory at the University of Lisbon is a modern analytical facility designed to offer high-quality results both to research and applied-oriented studies.

Germany / German Electron Synchrotron

DESY operates a test beam facility with three test beam lines. These electron or positron beams are converted bremsstrahlung beams from carbon fibre targets in the electron-positron synchrotron DESY II with up to 8000 particles per cm?and second, energies from 1 to 6 GeV, an energy spread of ~5% and a divergence of ~1mrad.Access to Test Beam at DESY has been supported by EC via EUDET/FP6 and AIDA/FP7.

Sweden / Self-standing

Abisko Scientific Research Station is a unique, modern and comprehensive infrastructure situated about 200 km north of the Arctic Circle in Sweden. It has international-standard facilities that support a range of research from observation and monitoring to high-tech experimentation within terrestrial and freshwater environments. The surroundings are characterised by a high variability of topography, geology and climate. The oldest house at the station was built in 1912, and meteorological monitoring and natural science research started in 1913. The station now holds a unique environmental record that extends 100 years back in time, as well as a vast portfolio of research activities totalling some 3,000 scientific publications. The station’s long-term records consist of many environmental variables such as climate, snow depth, ice thickness and ice duration on Torneträsk. The monitoring also includes hydrology, water chemistry, flora and fauna, as well as phenology, geomagnetism and atmospheric carbon isotope composition. The studies today range from terrestrial ecology and limnology, via climate change and earth sciences, to space physics.

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.
