A semiconducting/ferromagnetic nanocomposite, consisting of a porosified silicon wafer and deposited Ni-nanostructures, is presented. Porous silicon matrices achieved by anodization of a highly n doped wafer offer oriented pores with an average pore-diameter of 80 nm. Within these pores Ni-nanostructures are deposited resulting in a ferromagnetic system with specific magnetic properties. SEM and TEM investigations are performed to get a correlation between morphology and magnetic behavior.

Martensitic VM12 steel was recently developed for advanced coal-fired power stations. Its creep resistance is dependent on a stability of microstructure. Destabilization of microstructure is caused by recovery and softening processes of a tempered martensite and depends on changes of a dislocation substructure and morphology of secondary particles during creep. Quantitative TEM analyses of VM12 steel were undertaken to determine the microstructure parameters after creep at 625°C up to 30.000h.

Diplozoid monogenean Eudiplozoon nipponicum, with complex life cycle comprising oncomiracidium, diporpa, juvenile and adult stage, represents an ideal model for studies on morphological adaptations of metazoan parasites to the ectoparasitic life style. Combined morphological approach offers the advantage of more complex characterization and visualization of structures noticeable only when using specific microscopic method.

The combination of serial block-face scanning electron microscopy and energy dispersive x-ray spectroscopy (EDS) is demonstrated for 3D elemental analysis of materials, enabling investigations of large sample volumes compared to other tomographic techniques. The approach involves cutting a stack of 200 slices from an aluminum-copper alloy specimen and generating EDS maps after each cut.

The analysis of light elements (from Be to F, refer to periodic table in fig. 1) presents a special challenge for energy dispersive X-ray spectrometry (EDS). Some of the problems are due to inherent physical effects, while others are technical in nature, relating to the design of the instrument used for analysis and the measurement procedure. Along with the demand for fast and efficient tools for analysis at the micro- and nanometer scale, the need for light element analysis with EDS has grown.

The small size of micro- and nano-structures makes tensile testing challenging. In this study we meet this challenge by combined use of a Focussed Ion Beam (FIB) in Dual Beam configuration, an AFM-cantilever, and a micromanipulator which provide the required accuracy and versatility to measure the mechanical properties of nanowires by tensile testing. AFM cantilevers with a big range of force constants principally enable us to measure the tensile behavior of a great variety of materials.

ESEM (Environmental Scanning Electron Microscopy) enables the investigation of native, hydrated and uncoated plant surfaces without further sample preparation and the in situ observation of dynamic processes at SEM resolution. A selection of representative plant samples and applications will be presented to show that ESEM is a versatile tool in plant science.
