New Findings from Technical University Describe Advances in Chalcogens

February 18, 2014



By a News Reporter-Staff News Editor at Life Science Weekly -- Researchers detail new data in Chalcogens. According to news reporting originating from Hamburg, Germany, by NewsRx correspondents, research stated, "We present a comprehensive neutron scattering study on solid oxygen spatially confined in 12 nm wide alumina nanochannels. Elastic scattering experiments reveal a structural phase sequence known from bulk oxygen."

Our news editors obtained a quote from the research from Technical University, "With decreasing temperature cubic gamma-, orthorhombic beta- and monoclinic alpha-phases are unambiguously identified in confinement. Weak antiferromagnetic ordering is observed in the confined monoclinic alpha-phase. Rocking scans reveal that oxygen nanocrystals inside the tubular channels do not form an isotropic powder."

According to the news editors, the research concluded: "Rather, they exhibit preferred orientations depending on thermal history and the very mechanisms, which guide the structural transitions."
