Computerized Crystal Orientation

Review of Scientific Instruments, 1973
A computer program has been developed for accurately and rapidly determining the Miller indices for any number of Laue diffraction spots for a crystal of any symmetry and with arbitrary orientation relative to the x-ray beam. Using the xy coordinates of each Laue spot the program goes directly to the assignment and verification of the Miller indices ...

Light scattering by randomly oriented crystals

Applied Optics, 1989
The scattering phase function and the degree of linear polarization for small crystals oriented randomly in space have been computed using the geometric ray tracing theory and assuming that the crystals are homogeneous and isotropic. Calculations have been carried out for the main crystal geometries.

Crystal Sphere Orienter

Review of Scientific Instruments, 1963
A crystal sphere orienter for nonopaque crystals has been designed. It is used in conjunction with a petrographic microscope to orient crystal spheres optically.

Oriented crystallization in polymers

Journal of Macromolecular Science, Part B, 1967
Molten crystallizable polymer is extruded through an orifice. Opposite the orifice on the upstream side is a fixed surface arranged so as to provide in the molten polymer a line of uniaxial extension or a plane of pure shear passing through the orifice.

The fundamentals of crystal orientation

Acta Crystallographica Section A Foundations and Advances, 2018
The method described in this paper improves the old methods of crystal orientation, applies new parametric equations for crystallography, and increases the precision and accuracy of measurements. The method applies to inorganic and organic crystals. A breakthrough in crystal orientation happened about 25 years ago when two equations dependent on the ...

Orientation of Single Crystals

1974
The orientation of single crystals involves two basic tasks: the determining an unknown orientation and setting a sample in desired orientation. In order to explain our method we proceed in the following manner: First we describe the experimental setup for taking pictures of Laue back-reflection patterns and the conventional back-reflection Laue method

Crystal orientation effect under microgravity conditions

Journal of Crystal Growth, 1996
Attempts to grow single crystals of copper II oxalate by homogeneous chemical reaction under microgravity conditions have resulted in the observation of a curious crystallite orientation effect. A possible explanation of the effect in terms of weak magnetic fields is suggested.

Molecular Orientation in Liquid Crystal Elastomers

Macromolecules, 2005
Free-standing and confined anisotropic liquid crystal elastomer films of various thicknesses have been prepared using mesogens with laterally affixed polymerizable side chains. Textures have been studied by microscopy, whereas molecular orienation of the mesogen groups has been investigated by polarized FTIR and Raman spectroscopies considering an ...
