We propose a method for filtering convergent light beams with arbitrary polarization. For this purpose, a tandem of similar acousto-optic tunable filters was applied. Owing to the special mutual orientation of the cells, two coincident beams with ordinary and extraordinary polarizations were diffracted by the first crystal and the second crystal, respectively.

Semiconductor substrates made from single crystal materials need to be cut precisely along a fixed axis during the manufacturing process of the semiconductor components. Thus, measuring the crystal orientation is critical. For these measurements, Xray techniques demonstrate the highest precision. This report presents an outline of two popular X-ray diffraction techniques, the diffractometer and...

A "crystal hotel" microfluidic device that allows crystal growth in confined volumes to be studied in situ is used to produce large calcite single crystals with predefined crystallographic orientation, microstructure, and shape by control of the detailed physical environment, flow, and surface chemistry. This general approach can be extended to form technologically important, nanopatterned sing...

β-type Ti-29Nb-13Ta-4.6Zr alloy is a promising novel material for biomedical applications. We have proposed a 'single crystalline β-Ti implant' as new hard tissue replacements for suppressing the stress shielding by achieving a drastic reduction in the Young's modulus. To develop this, the orientation dependence of the plastic deformation behavior of the Ti-29Nb-13Ta-4.6Zr single crystal was fi...

The orientation boundaries in a liquid crystal can be characterized by topological charge that always sums to one, no matter the shape of container. n

We investigate the electrical behavior of a symmetric liquid crystal (LC) cell: elecrode-silane-LC-silane-electrode. The silane (chlorodimethyloctadecyl-silane) layer induces a homeotropic orientation of the nematic liquid crystal (NLC) molecules. The wettability technique is used to detect the change of the surface energy of the electrode upon cleaning and silane layer deposition. We report on...
