Characterization of mannitol in Curvularia protuberata hyphae by FTIR and Raman spectromicroscopy.
FTIR and Raman spectromicroscopy were used to characterize the composition of Curvularia protuberata hyphae, and to compare a strain isolated from plants inhabiting geothermal soils with a non-geothermal isolate. Thermal IR source images of hyphae have been acquired with a 64 × 64 element focal plane array detector; single point IR spectra have been obtained with synchrotron source light. In so...
متن کاملElectron backscatter diffraction (EBSD) in the SEM: applications to microstructures in minerals and rocks and recent technological advancements
Electron backscatter diffraction (EBSD) is based on the principle that a beam of electrons generated in the scanning electron microscope (SEM) is the source of randomly scattered electrons in a specimen. The backscattered electrons (BSE) that escape the sample generate a Kikuchi pattern on a phosphor screen, which is linked to the specimen crystal structure. Different crystal orientations gener...
متن کاملRaman and SEM analysis of a biocolonised hot spring travertine terrace in Svalbard, Norway
BACKGROUND A profile across 8 layers from a fossil travertine terrace from a low temperature geothermal spring located in Svalbard, Norway has been studied using both Raman spectroscopy and SEM (Scanning Electron Microscopy) techniques to identify minerals and organic life signals. RESULTS Calcite, anatase, quartz, haematite, magnetite and graphite as well as scytonemin, three different carot...
متن کاملSEM and Raman studies of annealed nanocrystalline GaN and amorphous GaN:O
We report annealing studies of thin films of GaN and GaN:O prepared by ion assisted deposition. As-prepared films of stoichiometric tetrahedrally bonded GaN form nanocrystalline networks, but amorphous networks result with the inclusion of more than 10 at.% of oxygen. The annealed nc-GaN films show an increased average crystallite size, though even after a 700 C anneal the crystals are no large...
متن کاملبررسی کانی شناختی فیروزه های ایران به وسیله مطالعات xrd, ftir, sem, raman
فیروزه (turquoise) یک آلومینوفسفات آبدار مس با فرمول cual6(po4)4(oh)8.5h2o است (frost, 2006). نام تورکویز (turquoise) که به معنای سنگ ترکی است، از این جهت بر روی این کانی ارزشمند ایرانی نهاده شد که در زمان های باستان به منظور صادرات فیروزه به سایر کشورهای دور و نزدیک، پس از استخراج رگه های این سنگ از معادن برای تراش، آن را ابتدا به کشور عثمانی (ترکیه حاضر) فرستاده و سپس قسمت عمده آن از طریق جاد...
