Pure Glycerine

The prevailing method of preparing glycerine mounts of nematodes consists essentially of transferring the specimens from the fixative to 1.5-2.0 per cent glycerine in water and then allowing the water to evaporate very slowly until the nematodes are in pure glycerine. By this method evaporation is completed in not less than four weeks as any attempt to hurry this process will distort the specimens. A desiccator is used to complete the removal of the water from the glycerine.

Backscattered Electron

The study of preferred crystallographic orientation (texture) in ceramics is assuming greater importance as their anisotropic crystal properties are being used to advantage in an increasing number of applications. The quantification of texture by a reliable and rapid method is required. Analysis of backscattered electron Kikuchi patterns (BEKPs) can be used to provide the crystallographic orientation of as many grains as time and resources allow. The technique is relatively slow, particularly for noncubic materials, but the data are more accurate than any comparable technique when a sufficient number of grains are analyzed. Thus, BEKP is well-suited as a verification method for data obtained in faster ways, such as x-ray or neutron diffraction. We have compared texture data obtained using BEKP, x-ray diffraction and neutron diffraction. Alumina specimens displaying differing levels of axisymmetric (0001) texture normal to the specimen surface were investigated.BEKP patterns were obtained from about a hundred grains selected at random in each specimen.
