Sentence examples for apt specimen from inspiring English sources
Several recent studies have employed H charging where deuterium is introduced into the atom probe tomography (APT) specimen tip as a substitute for the H to be measured in an iron/vanadium (Fe/V) multilayer film [4], steels [5 7], silver (Ag) [7], zirconium (Zr) alloys [8], and silicon (Si) [9].
Three sources of residual H2 gas that adsorb to the APT specimen tip may occur: (1) direct adsorption of H2 gas, (2) impingement and dissociation of H2O molecules, and possibly (3) surface diffusion of H2 gas along the shank of the tip due to a thermal or field gradient as suggested in Refs. [10, 18].
We showcase this framework by analyzing several regions of interest in a point cloud Al Mg Sc (Aluminium Magnesium Scandium) specimen APT data and extract several interesting measures describing the precipitate topology like area, volume, and nonconvexity.
The test specimen for the APT was prepared as a pavement system with an AC layer of 30 cm, subbase of 30 cm, and subgrade of 180 cm.
Sample preparation is one of the major challenges in correlative microscopy of a single specimen; it needs to be apt for both FM and TEM imaging.
Hence, correlative crystallographic characterization is required in addition to APT at the exact same location of the specimen.
In this schematic, the limits between the APT data (corresponding to a cylindrical area because of the needle-shaped specimen, as mentioned earlier) and the simulated data added to avoid any boundary effects is highlighted.
A conventional APT relies on the basic principle of the field evaporation of atoms from the surface of a specimen under high-voltage (HV) pulses [4, 5].
APTs were performed, and biopsy specimens were taken from all these sites (time = 0 and 24 hours) for immunohistochemical analysis.
