Cobalt doped ceria for abundant storage of surface active oxygen and efficient elemental mercury oxidation in coal combustion flue gas

Applied Catalysis B: Environmental, 2018
Abstract Cobalt doped CeO2 (Co-CeO2) prepared by a single-step hydrothermal method was used for Hg0 catalytic oxidation. The catalysts were characterized by scanning electron microscope, transmission electron microscope, X-ray diffraction, Raman spectroscopy, electron paramagnetic resonance, X-ray photoelectron spectroscopy, H2-temperature programmed

Variation in some element contents of water hyacinth due to cadmium or nickel treatment with or without anionic surface active agents

Journal of Environmental Science and Health . Part A: Environmental Science and Engineering, 1989
Abstract The changes in some metal components of water hyacinth by exposure to cadmium, nickel with or without surface‐active agents are determined. Metal contents of Cd, Ni, Al, Ca, Si, Mn in tops and roots were changed in relatively short time by treatment with Cd or Ni. The values of concentration factors are reduced in both tops and roots under the

A Multifunctional Active Frequency Selective Surface With Scattering Diffusivity and Transmission Passband Tunability

IEEE Antennas and Wireless Propagation Letters
In this letter, a multifunctional active frequency selective surface (AFSS) is proposed. In addition to forming several continuously tunable transmission windows in the operating band, it can also maintain low radar cross section (RCS) characteristics ...
