Voltage-dependent anchoring of a nematic liquid crystal on a grating surface
Article Abstract:
Placing a nematic liquid between a flat surface treated to induce a parallel anchoring of the director and a grating surface treated to give a perpendicular anchoring produces an effective aximuthal anchoring at the grating surface. This anchoring depends on the applied voltage when the nematic phase has negative dielectric anistropy. Gratings with lower anchoring energies need a lower tilt to be achieved close to the grating surface before the effective grating anchoring energy can overcome the twist threshold energy.

Continuous grey-scale image storage using optically aligned nematic liquid crystals
Article Abstract:
Polarized light is used to induce alignment of molecules over macroscopic lengths with high-spatial resolution for storing high-resolution, regular, grey-scale images on liquid crystals. These images can be easily erased. The method has a high potential in economical high-density image storage applications. Need for further research in optical and alignment properties of liquid crystals for realizing full potential of their capacities is discussed.

The optically dark side of galaxy formation
Article Abstract:
Cosmology research indicates that stars forming at high-redshift occurs in dust-ridden starburst space, making them difficult to detect. A far-infrared survey which accommodates dust thermal emissions is proposed to study star populations in high-redshift space. The technique, which involves the detection of cosmic infrared background components, identifies small-scale cirrus fluctuations and will be useful in future galaxy formation studies.
