Optical anisotropy in single-walled carbon nanotubes.

Optical anistropy at optical communication wavelength was observed in films of vertically aligned single-walled carbon nanotubes (SWNTs). We report the control of both the polarization state and transmission of incoming light at 1550 nm by azimuthal and axial tilting of SWNT film about its aligned axis. The experiments reveal that the polarization state of light is susceptible to the azimuthal angle of the aligned direction of a SWNT having semiconductor characteristics and the intensity of the output beam after SWNT film shows cosine function dependence on the axial tilting angle.

Isolation of cDNA including a reverse transcriptase-like sequence transcribed from the long interspersed repetitive DNA sequence of rat.

The mammalian genome congains long interspersed repetitive sequences, but the role of these repetitive sequence is not clear. A cDNA clone has been isolated that contains part of the L1 sequences from a cDNA library of rat liver. The DNA sequence analysis showed the homology of cDNA to several reverse transcriptases. The homology between the amino acid sequences predicted from L1 consensus sequences and reverse transcriptases has been reported previously. However, this is the first isolation of a cDNA clone containing a reverse transcriptase-like sequence.
