Research from Seoul National University reveals new findings on science

  2008 NOV 24 - (VerticalNews.com) -- According to a study from Seoul, South Korea, "We report the synthesis of atypical nanoparticles in donut shape with or without additional spherical nanoparticles attached on them by using the donut-like nanostructure formed in a thin film of triblock copolymers. In a high-humidity condition, a spin-coated film of triblock copolymer had donut-like holes consisting of the periphery and the center."

  "By selective coordination of precursors of nanoparticles to the periphery of the holes, donut-like oxide nanoparticles were synthesized by oxygen plasma treatment on the film. Moreover, we were able to attach spherical nanoparticles on the donut-like nanoparticles by incorporating the other type of precursors to the center of the holes," wrote S.M. Jeon and colleagues, Seoul National University.

  The researchers concluded: "Thus, beyond the synthesis of typical spherical nanoparticles, the results here extend potentials of the block copolymer approach to control the shape and complexity of nanoparticles."

  Jeon and colleagues published their study in Langmuir (Synthesis of atypical nanoparticles by the nanostructure in thin films of triblock copolymers. Langmuir, 2008;24(19):11137-11140).
