State of the Art Microanalysis Using Raman Microscopy
Introduction Raman spectroscopy is one of the most common techniques for materials identification and characterization. Based on inelastic scattering of a monochromatic excitation source, Raman measures vibrational, rotational and other low-frequency modes in a system. It’s not only characteristic for functional groups, but also sensitive to backbone and crystalline structures. Therefore, Raman...
متن کاملElements of image processing in localization microscopy
Localization microscopy software generally contains three elements: a localization algorithm to determine fluorophore positions on a specimen, a quality control method to exclude imprecise localizations, and a visualization technique to reconstruct an image of the specimen. Such algorithms may be designed for either sparse or partially overlapping (dense) fluorescence image data, and making a s...
متن کاملMicroscopy and Microanalysis Characterization Techniques used to Investigate Cultural Heritage Materials, Paintings and Pigments
Conservation involves the conservation and preservation of museum objects and historical monuments utilizing compositional and structural information obtained from modern analytical techniques. The conservation of oil paintings requires an understanding of the individual structure of each work of art. This often involves the need for 1) correct identification of the pigments used by the artist,...
متن کاملConcentration of elements in mitotic chromatin as measured by x-ray microanalysis
Unfixed frozen-dried and uncoated tissue sections of the mouse duodenum were placed on carbon planchets and analyzed in a scanning electron microscope fitted with energy dispersive X-ray equipment. Computer analysis of the X-ray spectra allowed elemental microanalysis of the nucleus, cytoplasm, and mitotic chromatin regions in the cryptal and villus enterocytes. The peak to continuum ratio of S...
متن کاملElectron probe microanalysis of ion exchange of selected elements between dentine and adhesive restorative materials.
BACKGROUND There have been numerous attempts to demonstrate the phenomenon of ion exchange between auto cure glass ionomer cements (GICs) and dentine. The purpose of this study was to employ an electron probe microanalysis (EPMA) technique to examine the interchange of elements between non-demineralized dentine and two types of restorative material, auto cure GICs and a resin composite. METHO...
