Recently, a research team led by Prof. LI Yue from Institute of solid State Physics, Chinese Academy of Sciences (ISSP), working in partnership with Prof. Li Cuncheng from University of Jinan, has developed a one-pot synthesis of ultrasmooth, precisely shaped gold nanospheres via surface self-polishing etching and regrowth.
Thanks to the various energy in nature, young sunflowers can track the sun’s movement because of the asymmetric elongation on opposite sides of stems from the solar irradiation; Drosophila melanogaster can sense and fly toward a light source to produce phototactic motion. These plants and insects have evolved the capability of responding to the change of environmental stimuli and producing corresponding mechanical motions.
Recently, the research team led by prof. KONG Lingtao at Institute of Solid State Physics, Hefei Institutes of Physical Science developed a highly active carbon framework-encapsulated copper oxide Fenton-like catalyst that can generate free radicals and singlet oxygen by activating peroxymonosulfate (PMS), realizing the efficient degradation of tetracycline pollutants in water.
Hefei Institutes of Physical Science had compiled and published a book titled Environmental Optics and Technology that summarizes the achievements of environmental optical monitoring technology, the self-developed three-dimensional monitoring system, and its application.
Some doped semiconductor, such as nonstoichiometric copper chalcogenides and oxygen-deficient metal oxides, showed surface plasmon resonance (SPR) effect, which usually existed in noble metal nanostructures. These materials are welcomed for their low cost. However, the optical response range of plasmonic semiconductor materials was mostly in the infrared region, which is not efficient for utilization of solar energy.
