Scanning Electron Microscopy Laboratory

Universita di Napoli Federico II
Type: infrastructure
Science area: 1. Natural Sciences2. Engineering and Technology6. Humanities

Laboratory of Scanning Electron Microscopy (SEM) at DiSTAR is equipped with a SEM Jeol JSM5310 and a FESEM ZEISS Merlin VP. They both allow the investigation of the microstructure and morphology of raw inorganic and suitably prepared organic materials, through the acquisition of high resolution magnified digital images.
SEM Jeol JSM5310, in the lab since 1998, provides both 3D images through a secondary electron detector (SE) and topographic and compositional images through a backscattered electron detector (BSE). It is also equipped with an EDS X-Stream Inca Oxford detector that supplies qualitative evaluation of chemical elements starting from fluorine. A well performing reference standardization allows single point analyses of polished samples (resin embedded or thin sections).
The FESEM ZEISS Merlin VP SEM, available in the lab since 2017, works both in high vacuum and in variable pressure and reaches 1 million magnification. The very large vacuum chamber of Gemini 2 apparatus hosts samples up to 15 cm diameter. This SEM is equipped with an “”inlens”” detector of both secondary and backscattered electrons, a normal secondary electron detector and a variable pressure secondary electron detector. It is linked to an EDS Oxford X-Max detector and to a WDS Wave Oxford spectrometer equipped with 4 analytical crystals. The combined use of EDS and WDS analytical facilities allows the quantitative analysis of chemical elements starting from Boron. A dedicated software provides us with compositional maps for the automated evaluation of the mineralogical composition in an unknown sample. The FESEM facility allows non-destructive and non-invasive analyses of large samples, which makes this apparatus the most powerful tool for SEM investigation in cultural heritage and forensic geology fields. The laboratory is officially accredited for SEM analysis of asbestos, on both massive samples and airborne fibers.

Research Platform Advanced Materials

Universität Innsbruck
Type: expertise
Science area: 1. Natural Sciences2. Engineering and Technology

Research groups from four faculties (Pharmacy and Chemistry; Mathematics, Informatics and Physics; Geo- and Atmospheric Sciences; Technical Sciences) cooperate within this research focus in order to fully exploit the synergies between physics, chemistry, earth sciences, pharmaceutical technology, and civil engineering. Synergies and strength areas are found in the fields of clusters, polymorphism/phase transitions, catalysis-reactivity, high-pressure research and materials engineering. A particular strength of the research focus lies in high-pressure, high-temperature synthesis and characterization of materials, which results e.g. in hitherto inaccessible coordination geometries in solid state compounds. Thereby, fabrication of novel materials with tailored optical, electronic and mechanical properties becomes possible. Furthermore, elaborate technologies allow us to mimic conditions which are found deep in the earth mantle, thus permitting unprecedented insights into geomechanical and geochemical processes. Strong activities are focused on clusters in the gas phase and on surfaces. Basic questions ranging from the “magic” stability of clusters to the electronic structure and the possibility of tailor-making catalyst for chemical reactions are explored. Another important focus of the platform is the study of phase diagrams, phase transitions and of metastable materials, both in the bulk and in low-dimensional materials are investigated, including ferrolectric or superconductive materials. New concepts of phase transitions in amorphous systems, particularly water and ice, have resulted in the discovery of new phases and in new concepts such as cryocatalysis. The expertise in phase transitions, polymorphism and watersolid interactions is finally being exploited to obtain better control of drug formulation and performance.
