SEM–EDS analysis and discrimination of forensic soil
Forensic Science International, 2004Soils vary among different areas, and have some characteristics because of the natural effects and transfers made by human and other living beings in time. So that forensic examination of soil is not only concerned with the analysis of naturally occurring rocks, minerals, vegetation, and animal matter.

Fatigue fracture analysis of amalgam by SEM-EDS
Dental Materials, 1986Abstract The purpose of this study was to examine cracks generated in dental amalgam during compressive fatigue. Cracks were observed using SEM and composition was evaluated by Energy Dispersive X-ray Spectroscopy (EDS). Amalgam cylinders showed classical fatigue fracture.

SEM-EDS Investigations of Self-Phosphating Coatings
Industrial & Engineering Chemistry Research, 1994A one-pack paint composition comprising polyester-melamine enamels and a predispersed amount of either phosphoric acid (H 3 PO 4 , in situ phosphatizing reagent), p-toluenesulfonic acid (p-TSA, polymer catalyst), or hydrofluoric acid (HF, surface etching agent) was formulated, coated, and thermally cured on a cold-rolled steel panel.

Innovative unattended SEM-EDS analysis for asbestos fiber quantification
Talanta, 2018Scanning electron microscopy with energy dispersive spectrometry (SEM-EDS) is the only affordable analytical technique that can discriminate both morphology and elemental composition of inorganic fibers. SEM-EDS is indeed required to quantify asbestos in confounding natural matrixes (e.g. ophiolites), but is also time-consuming, operator dependent, and

SEM/EDS comparison of polar and seasonal temperate ice
Microscopy Research and Technique, 2003AbstractWe have developed a method employing a scanning electron microscope (SEM) and energy dispersive X‐ray spectroscopy for examining uncoated ice specimens. By permitting the ice to sublimate in the SEM at temperatures between −115° and −60°C, enough ions are produced to prevent specimen charging.

Analysis of microtraces in invasive traumas using SEM/EDS
Forensic Science International, 2012Scanning electron microscopy in combination with energy-dispersive X-ray spectrometry (SEM/EDS) is a proven forensic tool and has been used to analyze several kinds of trace evidence. A forensic application of SEM/EDS is the examination of morphological characteristics of tool marks that tools and instruments leave on bone.

Characterization of Pyrotechnic Reaction Residue Particles by SEM/EDS
Journal of Forensic Sciences, 2003Abstract Today the method commonly used for detecting gunshot residue is through the combined use of scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS). In recent years, this same methodology began to find use in detecting and characterizing pyrotechnic reaction residue (PRR) particles whether produced by ...

Automated SEM-EDS GSR Analysis for Turkish Ammunitions
AIP Conference Proceedings, 2007In this work, Automated Scanning Electron Microscopy with Energy Dispersive X‐ray Spectrometry (SEM‐EDS) was used to characterize 7.65 and 9mm cartridges Turkish ammunition. All samples were analyzed in a SEM Jeol JSM‐5600LV equipped BSE detector and a Link ISIS 300 (EDS).
