Equipment that analyzes the specimen by obtaining the result of bright field image, dark field image, diffraction pattern, etc. when the electron beam passes through the specimen and the transmission line and diffraction line come out. Acceleration voltage of electron beam can be used from 60 kV to 300 kV, and it is equipped with cryo-shield, so it can analyze samples at low temperature. Therefore, in order to analyze organic and organic / inorganic hybrid materials that were previously difficult to analyze due to the damage caused by high energy electron beams on the specimens, suitable acceleration voltages can be used flexibly and the specimens are disturbed by the growth of ice crystals at cryogenic temperatures. It is a transmission electron microscope that can be analyzed without receiving.

The Dust Accelerator facility located at Max Planck Institute for Nuclear Physics (MPIK) in Heidelberg is operated by the University of Stuttgart, Institute of Space Systems (IRS).A 2 MV electrostatic field accelerates micron- and sub-micron-sized dust particles to speeds between 0.5 and 100 km/s. Dust powder used are coated minerals (olivine, pyroxene), organics (coated polystyrene) or metals (Fe, Al, Ni, ...). The dust source provides approx. 30 particles per sec. The speed, charge and mass of each accelerated particle is measured in-situ. A selection electronics can selected individual particles within a certain speed or mass range.The target chambers are available (largest has 1.4 m diameter). A vacuum of 1e-6 mbar is applied.Tests are performed for space instrument development/calibration, space weathering, hyper-velocity impact physics (e.g. mass spectrometry).Studies at the dust accelerator are multi-disciplinary and are relevant in the field of geoscience, physics, chemistry, astrophysics and astrobiology. Phenomena under study include dust charging, dust magnetosphere interactions, dust impact flashes and the possibility of obtaining compositional measurements of impact plasma plumes. Such data has been shown to be of direct relevance to space missions like Galileo, Ulysses, Cassini, Rosetta, Stardust, New Horizon or BepiColombo. Future projects to the Moon, to the inner Solar System (Solar Probe Plus), to the Jovian system and to Saturn will carry dust instrumentation which has to be developed with the help of micrometeoroid impact simulations in the laboratory. The recent Stardust mission collected and returned samples of interplanetary and interstellar dust grains to Earth. Sample preparation and analysis requires the study and understanding of grain-collector material interaction during hypervelocity impacts. Test and calibration of dust collectors and of in-situ dust detectors onboard interplanetary probes or Earth satellites is a major application of the facility. The laboratory generation and analysis of in-situ mass spectra of high-speed organic micro-grain impacts is essential for astrobiology studies and provide the basis for an understanding of the composition of interplanetary or interstellar micrometeoroids. and

The objective of the Seismic Mechanic Studies Laboratory is to better understand the seismic behavior of components, equipment and structures, and to reduce the consequences of earthquakes (improvement of standards and diagnosis of existing facilities). The laboratory combines experimental and theoretical approaches. Research areas include modeling of structures under dynamic loading (seismic isolation, dynamic behavior of reinforced concrete structures, validation of structures under dynamic solicitation), deterministic and stochastic dynamic of non linear systems (stochastic dynamic for the calculation of seismic behavior, shaking table driving control, dynamic behavior of rotating machines), and interaction between fluid and structure.

Traversing proton beam-irradiated, mid/high-Z nanoparticles produce site-specific enhancement of X-ray photon-electron emission via the Coulomb nanoradiator (CNR) effect, resulting in a nano- to micro-scale therapeutic effect at the nanoparticle-uptake target site. Here, we demonstrate the uptake of iron oxide nanoparticles (IONs) and nanoradiator-mediated, site-specific thrombolysis without damaging the vascular endothelium in an arterial thrombosis mouse model. The enhancement of lowenergy electron (LEE) emission and reactive oxygen species (ROS) production from traversing proton beam-irradiated IONs was examined. Flow recovery was only observed in CNR-treated mice, and greater than 50% removal of the thrombus was achieved. A 2.5-fold greater reduction in the thrombusenabled flow recovery was observed in the CNR group compared with that observed in the untreated ION-only and proton-only control groups (p < 0.01). Enhancement of the X-ray photon-electron emission was evident from both the pronounced Shirley background in the electron yield and the 1.2- to 2.5-fold enhanced production of ROS by the proton-irradiated IONs, which suggests chemical degradation of the thrombus without potent emboli.

The irradiation of nitrogen ion beams alters the chemical structure of conjugated polymers including poly(3-hexylthiophene) (P3HT). The high dose nitrogen ion beams decompose conjugated polymers, which can be applied for dry patterning of conjugated polymer films. The P3HT strips patterned by the high dose nitrogen ion beams act as a good channel layer for organic field-effect transistors with reliable characteristics.

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.
