Cu-Zn-Sn shape memory alloy (SMA) strips with an essentially constant composition of 26 wt% Sn were fabricated by electrodepositing Sn onto a shim brass surface and then subsequently annealing the strips at a temperature range of 350°C to 420°C for 120 minutes under flowing nitrogen. Five-point probing of the cross-section of the strip by SEM-EDX was performed to verify the composition of the intermetallics present in the fabricated SMA...

Zinc oxide (ZnO) is a unique material that exhibits semiconducting as well as piezoelectric properties. Here an effort has been made to find out if there is formation of ZnO nanostructures in the Zn electrode of a Zn-C dry cell. Zinc electrodes from fully used Zn-C dry cells have been used for the analysis. SEM and EDX analysis of the ZnO structures formed on the Zn electrode of a Zn-C dry cell were performed...

Localised melting damage in electrical wiring is often observed following a fire, and is known as ‘arcing damage’. An SEM can be used to examine a conductor in detail; this paper explores the use of a confocal microscope as an alternative to an SEM. CLSM was used to analyse 65 samples of electrical conductor recovered from full-scale fire experiments that had also been analysed with an SEM...
