Polystyrene fibers were fabricated by electrospinning. Polystyrene resin was dissolved in chloroform, N,N-dimethylformamide, or their mixtures. In experiments with 10 wt-% solutions of polystyrene in various solvents, a 1:1 solvent mixture was found to be optimal. In the 1:1 solvent, an increase in polystyrene concentration resulted in a decrease in the number of beads on the electrospun fibers and an increase in their diameter. A 20 wt% solution of polystyrene gave fibers with a diameter of about 1.8 $m with almost no beads. Polystyrene fibers containing nanoparticles were prepared by electrospinning 20 wt% polystyrene solutions containing dispersed nanoparticles of TiO2 or ZnO. The concentrations of nanoparticles in the electrospun fibers, determined by energy dispersive X-ray spectroscopic analysis, were less than expected.

The advances in recent years in the microanalytical capabilities of conventional TEM's fitted with probe forming lenses allow much more detailed investigations to be made of the microstructures of complex alloys, such as ferritic steels, than have been possible previously. In particular, the identification of individual precipitate particles with dimensions of a few tens of nanometers in alloys containing high densities of several chemically and crystallographically different precipitate types is feasible. The aim of the investigation described in this paper was to establish a method which allowed individual particle identification to be made in a few seconds so that large numbers of particles could be examined in a few hours.A Philips EM400 microscope, fitted with the scanning transmission (STEM) objective lens pole-pieces and an EDAX energy dispersive X-ray analyser, was used at 120 kV with a thermal W hairpin filament. The precipitates examined were extracted using a standard C replica technique from specimens of a 2¼Cr-lMo ferritic steel in a quenched and tempered condition.

Instruments combining a 100 kV transmission electron microscope (TEM) with scanning transmission (STEM), secondary electron (SEM) and x-ray energy dispersive spectrometer (EDS) attachments to give analytical capabilities are becoming increasingly available and useful. Some typical applications in the field of materials science which make use of the small probe size and thin specimen geometry are the chemical analysis of small precipitates contained within a thin foil and the measurement of chemical concentration profiles near microstructural features such as grain boundaries, point defect clusters, dislocations, or precipitates. Quantitative x-ray analysis of bulk samples using EDS on a conventional SEM is reasonably well established, but much less work has been performed on thin metal foils using the higher accelerating voltages available in TEM based instruments.
