Characterisation of nanoparticles by means of high-resolution SEM/EDS in transmission mode

Polyethylene Glycol as Shape and Size Controller for the Hydrothermal Synthesis of SrTiO3 Cubes and Polyhedra

“…Further, energy dispersive X-ray spectroscopy (EDS) with a highly sensitive UltraDry Silicon Drift Detector (SDD) (Thermo Fisher Scientific, Waltham, MA, USA) of a nominal 100 mm 2 crystal area can be applied in the STEM-in-SEM mode. Hence, spatial resolutions for EDS down to ≈10 nm can be attained [ 29 ]. Due to the complex geometry of the sub-µm particles (non-planar surface), an elemental quantification with EDS coupled with the transmission mode is not applicable by the conventional bulk analysis approaches.…”

Improving the foundation for particulate matter risk assessment by individual nanoparticle statistics from electron microscopy analysis

“…Scanning electron microscopes provides a lower resolutions, but recent advances have made it possible to automatically scan large areas of a sample, process the acquired images, locate particles, and perform subsequent EDS analysis without user intervention except for the initial setup 24,25 . As a result, automated SEM/EDS analysis makes it possible to obtain sufficient data on the single particle level to allow for a meaningful statistical analysis of an aerosol population, including both physical and elemental composition data 26 . Electron microscopy is however, an offline measurement technique and therefore only provides detailed information some time after sampling.…”

Analysis of Fluorine Traces in TiO2 Nanoplatelets by SEM/EDX, AES and TOF-SIMS

“…This holds also true for the reference, fluorine-free sample, TiO 2 nanoparticles of bipyramidal shape ( Fig. 1 bottom right) [2][3][4][5]. This type of material has been prepared by a different synthesis route.…”
