1. INTRODUCTION The discovery of single-walled carbon nanotubes (SWNTs) in 1993 by Iijima and Ichihashi [1] has stimulated many researchers to utilize for the innovative technology, especially applications to electronic or optic devices in which SWNTs are used as grown on substrates. However, the technical development for decreasing impurities and defects, controlling physical properties, shape...
Previous studies have showed that insulin-like growth factor (IGF) axis is involved in the development of hypertension. It is unclear whether genetic variants in the IGF-binding proteins (IGFBPs) contribute to the susceptibility to hypertension. Three single-nucleotide polymorphisms (SNPs) in IGFBP1 and four SNPs in IGFBP3 were selected for genotyping in 2,012 hypertension cases and 2,210 healt...
We present a Raman spectroscopy study of iodine-intercalated (p-type doped) double-walled carbon nanotubes. Double-walled carbon nanotubes (DWCNTs) are synthesized by catalytic chemical vapor deposition (CCVD) and characterized by Raman spectroscopy. The assignment of the radial breathing modes and the tangential modes of pristine DWCNTs is done in the framework of the bond polarization theory,...
The results are given of a questionnaire study to determine the range of difficulties that doctors notice in their work due to congenital colour vision deficiency (CCVD). The study is primarily qualitative. A questionnaire was sent to 40 self-selected doctors, 35 of whom were general practitioners (GPs). All were administered a number of colour vision tests to assess the type and severity of th...
