SEM-EDS is the go-to method for the characterisation of many materials and is being used increasingly to meet the characterisation challenges associated with some key areas of polymer research and manufacturing.

Lithium Ion batteries are found in most mobile electronic devices (e.g. laptop computers, phones etc).

Abstract. This study investigates the changes in radial micro-texture via Kearn’s f-factors during single cold pilger reduction of a titanium Ti-3-2.5 alloy as a result of strain path changes from tooling modifications. EBSD results confirm that the texture intensity as well as the radial f-factors can be increased by modifications of pilgering tooling. In addition a switch between the secondary prism planes which lie normal to the pilger direction in the starting tube to primary prism planes after pilgering has been observed. Material and Experimental The tubes investigated were made from Ti alloy 3Al 2.5V, they were manufactured via hot extrusion and then cold pilgered. The cold pilger process configuration is schematically shown in Figure 1. Two strain paths, shown in the ‘Q‘ factor chart in Figure 2, were used in the manufactiure: texture minimised and texture maximised. They were annealed at 750oC before being cold pilgered and for this investigation they were stress relieved at 530oC for 2 hours prior to EBSD examination. Specimens were extracted from two regions either side of the reduced tube as shown in the schematic Figure 2, mounted in conductive Bakelite and polished mechanically for EBSD examination. The final polish was carried out using vibratory polishes using a mixture of 5:2 colloidal silica, hydrogen peroxide mixture. EBSD examination was conducted using a FEGSEM and OI EBSD Nordlys detector and AZtec Software.

The X-MaxN series of large area SDD detectors are revolutionising the EDS analysis of biological samples. With sensor active area up to 150 mm2, and the possibility to combine multiple detectors to make an effective area of up to 600 mm2, counts from samples are maximised even at low kV and small spot sizes. At last, ultra-fast analysis and nano-scale accurate mapping on biological materials are not only possible, but practical too.

Mineral liberation is a critical stage in the production of high quality mineralogical concentrates from their ores. The products (concentrates) must be of a suitable degree of purity for the downstream processes in which they will be used. The original mined ore must be processed via comminution (crushing, grinding and classification) to liberate the desired minerals from it and via concentration (froth flotation, gravity separation, magnetic separation) to enrich the mineral content to the desired level. In order to design, diagnose, monitor and optimise the process, information is needed on the extent to which the valuable mineral grains have been released from the accompanying gangue minerals (degree of liberation) and to which form they are lost in tailings (deportment studies).

Introduction Application Note As semiconductor devices continue to decrease in size to improve performance and take advantage of advances in fabrication techniques, there is a need to analyse both their structure and chemistry at ever increasing resolution. Typically this requires the use of TEM for metrology and failure analysis. Using ultrahigh resolution FEG-SEM, low kV imaging and the new X-Max® Extreme EDS detector we demonstrate the ability to retain some of this high resolution analysis in the SEM. This allows for better targeting of resources and increased throughput of analysis.

An important part of the research and development of thin-film solar cells is the characterisation of microstructural and compositional properties of the functional layers. For this purpose, energy-dispersive X-ray spectrometry (EDS) and electron backscatter diffraction (EBSD) represent techniques which exhibit spatial resolutions on the nanometer scale but can be, at the same time, applied on large areas of several square millimeters. The application of EDS and EBSD is demonstrated on this example of thin-film solar cells with Cu(In,Ga)Se2 absorber layers. While EDS provides elemental distributions even in layers with a nominal thickness of 30-50 nm, EBSD gives not only information of average grain sizes, local orientations and grain boundaries. Moreover, strain distributions within individual grains can be calculated by the evaluation of EBSD patterns recorded on individual grains.

Gunshot residue (GSR) is produced from the condensation of the vapour cloud which is generated from the primer and propellant when a bullet is fired from a gun. The condensing vapour from the primer will form particles which are typically spherical and range from potentially less than 0.5 μm up to significantly larger sizes and of a characteristic composition depending on the type of ammunition. These particles may land on the hands and body of the shooter or other persons present when the gun was fired. By collecting and identifying these particles it is possible to associate a person with a crime scene where a gun was used

Development and testing of semiconductor devices requires extensive knowledge of local structure and elemental composition. With feature sizes of <5 nm, it is often necessary to perform imaging and EDS analysis in a S / TEM. Once in the TEM, there are still many difficulties to be overcome to acquire accurate elemental maps. Elemental analysis of semiconductors is typically difficult due to strong overlaps of X-ray lines between commonly used elements and low concentrations of dopants. Not only are concentrations of dopants small but their X-ray lines often overlap with other materials used in semiconductor processing. This brief shows how AZtecTEM solves these overlaps to achieve an accurate elemental analysis. TEM Semiconductor Mapping in the TEM Solving peak overlaps in real-time Application Brief
