Ion Beam Analysis: Analytical Applications
Published in Vlado Valković, Low Energy Particle Accelerator-Based Technologies and Their Applications, 2022
Typical applications of the technique include:Assessment of degree of crystalline perfection in annealing treatments.Measurement of damage or damage profile from ion implantation.Location of lattice position of impurities.Measurement of thickness of amorphous layers on single-crystal substrates.Assessment of degree of epitaxy in grown structures.Measurement of light element (C, O, N) surface contaminants.
Tissue burden evaluation of elongated mineral particles in two individuals with mesothelioma and whose work history included manufacturing tile
Published in Ultrastructural Pathology, 2020
Any structure detected in ATEM count areas that met the aforementioned definition of a “fiber” or the core of an elongated ferruginous body was evaluated for crystalline characteristics by selected area electron diffraction (SAED) to confirm a pattern as amphibole, serpentine, talc or other crystalline or non-crystalline pattern. The SAED pattern/zone axis was used to distinguish talc fibers from anthophyllite asbestos fibers as was the less complex but evident changes in SAED discrimination between talc fibers and anthophyllite asbestos fibers as recognized by users of ATEM instruments with tilting the specimen stage and described in detail by Millette30 and ISO 22262–1 Annex F.3.31 Further identification as to the mineral characterization was achieved by determination of elemental composition by energy-dispersive spectroscopy. This elemental composition of the elongated particulates was determined by use of an IXRF Systems analyzer model 550i and AAT light element detector with 144-eV resolution running Iridium Ultra Version 1.4.D software. A second analysis was conducted at 2,000x on 20 additional grid squares on each of the three grids (total of 60 grid squares). The data from this scan as reported were conducted with an objective to find ferruginous bodies for core analysis.
