the present study investigates the crystal preferred orientation (cpo) of quartz crystals in psammitic rocks to ascertain the deformationmechanism using electron backscatter diffraction (ebsd) on quartz crystals from north of the renvyle-bofin slide (rbs) nearletterfrack in western ireland. complete crystallographic orientations were determined for several thousand individual quartz crystalsin ...

Effect of electro migration on crystal structures of platinum nanowire (Nano bridge) during Nano-gap formation is investigated by means of Transmission Electron Microscopy (TEM). Selected area diffraction patterns as well as bright field images are used for this investigation. There were severely recessions in the polycrystalline Nano bridge and crystal structures around the nanogap changed ...

It is known that the wing scales of the emerald-patched cattleheart butterfly, Parides sesostris, contain gyroid-type photonic crystals, which produce a green structural colour. However, the photonic crystal is not a single crystal that spreads over the entire scale, but it is separated into many small domains with different crystal orientations. As a photonic crystal generally has band gaps at...

Abstract The crystallographic textures produced during additive manufacturing can be understood, predicted, and manipulated by varying the grain nucleation growth processes. resultant are primarily dictated melt pool geometry, which defines local thermal gradient thus preferred crystal directions, as well scan strategy, controls propagation of orientations into subsequent layers. This texture d...
