The procedure detailed allows the projection and viewing of stereoscopic slides without the use of a special stereo projector or a polarizing screen; a standard lantern slide projector is used, and the slides are viewed through red and green acetate filters.A stereo pair is taken on a scanning electron microscope with a tilt difference of 7° (Fig. 1). After the first member of the pair is taken, the sample is tilted. The image is refocused by means of the z-axis control and recentered by means of the x- and y-axis controls. These two manipulations ensure that both micrographs in the stereo pair are at the same magnification and that they will be superimposed properly on the color slide.A Polaroid MP-3 Industrial Viewer, a Graflex 120 roll film back, and a framing table (or equivalent equipment) can be used to make stereo slides from stereo pairs.

Coloring pictures is an educational exercise, which is fun, and helps develop important skills. Coloring SEM micrographs is especially suitable for electron microscopists. Color micrographs are not just great looking on a lab wall; they inspire both microscopists and students to exercise digital picture manipulation. Many microscopists enjoyed looking at the beautiful color micrographs by D. Scharf, but were frustrated to learn they needed a very particular scanning electron microscope equipped with multiple secondary electron detectors in order to color their own pictures. Fortunately, there are other ways to color SEM micrographs. Most SEMs are equipped with at least two detectors, for secondary and backscattered electrons.

Seed morphology of 12 Iranian endemic and subendemic species of Veronica was studied using scanning electron microscope (SEM). Seven qualitative and quantitative characters were measured using SEM micrographs and stereomicroscopy. The seed shape of most species is ovate and plano-convex. The size of seeds ranges from 1.25 x 0.75 mm in V. khorassanica to 2.5 x 1.75 mm in V. viscosa Boiss. The ornamentation of seed coat is reticulate-verrucate in V. khorassanica, V. czerniakowskiana, V. mazanderanae and V. rubrifolia, reticulate-rugate in V. acrotheca, V. aucheri, V. viscosa and V. intercedens, rugose in V. microcarpa, V. chionantha and V. rechingeri, and reticulate-porate in V. gaubae. The testa cells are polygonal in ten species and irregular in two species. Micromorphological characters of seeds are useful in specific and subspecific delimitations of Iranian Veronica.

This paper summarizes the investigations of hydroentangled islands-in-the-sea (PA6/COPET) fiber webs. An increase in water jet pressure improved the tensile strength and fiber splitting while elongation at break decreased. Scanning Electron Microscope (SEM) micrographs and ANOVA (MS Excel ™) were used for characterizing fiber splitting and data analyses respectively. It can be concluded that with a new innovation in spinnerette design and modification of co-polyester structure, PA6/COPET, fibers can be split in the hydroentanglement process without dissolution of the sea component.

Scanning Electron

A variety of factors must be controlled in order to obtain stereo micrograph pairs with the SEM which provide maximum effectiveness along with ease of viewing. These include the following:1. Where possible, micrographs should be sharp from edge to edge. This may require the use of an Autofocus attachment although somewhat the same effect can be obtained by maintaining the point of sharpest focus near opposite edges of the two micrographs forming the stereo pair.2. The difference in tilt angle between the two micrographs of the pair should be kept in the 4to 6° range to provide a normal perspective.3. Micrographs forming a stereo pair should be made at relatively low tilt angles to prevent large differences in the field of view of the two micrographs and to minimize the left to right magnification variations.

The splitting of segmented pie filaments in spunbond is a direct impact on the performance of final products. After splitting process, one primary filament is fractured into several micro-filaments which own excellent properties. This paper was to investigate effects of splitting on segmented pie filaments when they were processed with different splitting technologies. Scanning Electron Microscope (SEM) micrographs were used for characterizing the splitting effect in order to discuss optimal splitting techniques to manufacture segmented pie spunbonded nonwovens. The results indicated that spunlacing and alkali deweighting can get a better splitting effect than the other process.

A technique was developed by which plaque accumulations on intraoral artificial surfaces could be viewed with a scanning electron microscope (SEM). Micrographs of two plaque specimens from a given individual appeared similar; however, plaque specimens from different individuals encompassed a wide range of variation in terms of content and thickness.
