ENFSI Proficiency Test Program on Identification of GSR by SEM/EDX

Journal of Forensic Sciences, 2003
Abstract Within the framework of the ENFSI Expert Working Group “Firearms,” a proficiency test on the detection and identification of GSR by SEM/EDX was organized and performed. The test material was designed by the Bundeskriminalamt and manufactured to order by an external company for SEM accessories. The participating laboratories were

SEM and EDX studies of bioactive hydroxyapatite coatings on titanium implants

Micron, 2009
This work presents a study on an alternative coating method based on biomimetic techniques which are designed to form a crystalline hydroxyapatite layer very similar to the process corresponding to the formation of natural bone. The HA formation on the surface of titanium alloy pretreated with NaOH solution is investigated.

SEM-EDX Characterisation of Tropospheric Aerosols in the Negev Desert (Israel)

Journal of Atmospheric Chemistry, 2003
Individual aerosol particles collected in the Negev desert in Israel during a summer and winter campaign in 1996–1997 were analysed by scanning electron microscopy with energy-dispersive X-ray analysis. Hierarchical cluster analysis was performed to interpret the data on the basis of particle diameter and composition.

Digital image processing of combined SEM and EDX signals

Journal of Microscopy, 1983
SUMMARYDue to the complexity of biological tissue and man‐made materials, the limits of light microscopy in quantitative image analysis are often reached. The scanning electron microscope provides a much higher resolution in such situations, especially when using the low noise secondary electrons signal.

Metallic Trace Contaminant Detection Using SEM/EDX

2019 IEEE 26th International Symposium on Physical and Failure Analysis of Integrated Circuits (IPFA), 2019
Surface characterization techniques such as Auger Electron Spectroscopy (AES) and X-ray Photoelectron Spectroscopy (XPS) are commonly used to analyze surface contaminants to determine their elemental composition and/or chemical states. However, one may not have easy access to these techniques due to high cost of ownership and stringent analysis ...

Characterization of pad surface defect by TEM, SEM and EDX

2009 16th IEEE International Symposium on the Physical and Failure Analysis of Integrated Circuits, 2009
Tiny defects were observed by SEM (Scanning Electron Microscopy) on pad surface. In order to identify the root cause, TEM (Transmission Electron Microscopy) and EDX (Energy dispersive X-ray) techniques were used to do failure analysis. The SEM images showed that the tiny surface defects were pits.

Argentinean prehistoric pigments’ study by combined SEM/EDX and molecular spectroscopy

Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy, 2010
Composition of the prehistoric pigments' (from Carriqueo rock shelter, Rio Negro province, Argentina) has been analysed by means of molecular spectroscopy (Fourier transform infrared (FTIR) and micro-Raman) and scanning electron microscopy (SEM) coupled to an energy-dispersive X-ray spectrometer (EDS). Red and yellow pigments were recognized as red and
