The EDXA showed that the dendrite is a phase with high concentration of Al, so that the ([gamma]-[gamma]') phase is in the matrix and the ([beta]-[gamma]') phase is in the dendrite core as indicated by Hunziker and Kurz [51] and Rosas et al.
The resulting SiC ceramics were analyzed with differential scanning calorimetry (DSC), Fourier transform infrared (FTIR) spectroscopy, scanning electron microscopy (SEM), and energy-dispersive X-ray analysis (EDXA) to monitor heat flow and physical, chemical, and structural changes during the formation of the ceramic.
These materials were deposited on a carbon (C)-conductive tape covering SEM stubs and analyzed by EDXA (Noran-Voyager analytical system; Thermo Scientific, Waltham, MA, USA) coupled in a Jeol 1200 EX scanning-transmission electron microscope (Jeol, Tokyo, Japan).
The elemental composition of the surface of the wood specimens before and after sol-gel treatment is shown in the EDXA spectra presented in Figs.

EDXA of untreated alfalfa stems yielded background levels of Mg, Si, P, S, Cl, and a preponderance of K as shown in representative spectra [ILLUSTRATION FOR FIGURE 4A OMITTED].
The structure morphology and composition of Ti-Nb-Zr-O samples were investigated using a scanning electron microscope (SEM; FEI SIRION 200, USA) equipped with energy dispersive X-ray analysis (EDXA; OXFORD INCA, USA).
In addition, XRD and EDXA analyses were used for studying the alloy layer formed on the work piece surface and phase and alloy changes because of the penetration of wire materials on the work piece surface.
Due to the inhomogeneity of the Vanua Lava source, the same area was excited with EDXA as used in LA-ICP-MS (~86 [micro]m in diameter).
Scanning electron microscopy (SEM) was used for fiber counting (detection limit: 0.4 F/L) and energy dispersive X-ray analysis (EDXA) for fiber identification, according to the Asbestos International Association (AIA) method (AIA 1984).
(3) utilized surface characterization techniques, including electron spectroscopy for chemical analysis (ESCA), energy dispersive X-ray analysis (EDXA), time-of-flight secondary ion mass spectrometry (TOFSIMS), and transmission electron microscopy (TEM), in attempts to elucidate the mechanism by which CPO primer coatings promoted adhesion of paints to polypropylene and TPO.
