A unique texture structure in the alumina ceramics produced by gel-casting and platelet seeding is investigated by electron backscatter diffraction (EBSD) together with X-ray pole figure analysis. The EBSD results not only confirm the texture symmetry observed by X-ray methods, but also provide information about in-plane orientation and grain boundary misorientation...

The problem of interfacial reaction between liquid slags and liquid copper is presented. The results of interaction in the carbide slag during copper refining were determined. Structural analysis was performed with analytical TEM...

We categorise alignments which affect the resolution of a TEM/STEM and describe a method for improving resolution using the electron Ronchigram. The effects of defocus and astigmatism on the Ronchigram are illustrated using a conventional tungsten source CM20 TEM, together with a ray diagram...

Fractal analysis is a mathematical tool that allows the quantification of the complexity of natural structures or phenomena. We used a modified box-counting method to assess the complexity or irregularity of the deep margin of T1-T2 tongue carcinoma (fractal dimension)...
