By a News Reporter-Staff News Editor at Science Letter -- Data detailed on Nanotubes have been presented. According to news reporting originating in Nagano, Japan, by NewsRx journalists, research stated, "Despite extensive research for more than 200 years, the experimental isolation of monatomic sulphur chains, which are believed to exhibit a conducting character, has eluded scientists. Here we report the synthesis of a previously unobserved composite material of elemental sulphur, consisting of monatomic chains stabilized in the constraining volume of a carbon nanotube."
The news reporters obtained a quote from the research from Shinshu University, "This one-dimensional phase is confirmed by high-resolution transmission electron microscopy and synchrotron X-ray diffraction. Interestingly, these one-dimensional sulphur chains exhibit long domain sizes of up to 160 nm and high thermal stability (~800 K). Synchrotron X-ray diffraction shows a sharp structural transition of the one-dimensional sulphur occurring at ~450-650 K. Our observations, and corresponding electronic structure and quantum transport calculations, indicate the conducting character of the one-dimensional sulphur chains under ambient pressure."
According to the news reporters, the research concluded: "This is in stark contrast to bulk sulphur that needs ultrahigh pressures exceeding ~90 GPa to become metallic."
