  • Regenerative Electrocatalytic Redox Cycle of Copper

    Electrochemical nitrogen reduction reaction (NRR) is a promising method for energy-efficient and low-emission NH3 production. Herein, we report electrochemical NH3 production using a copper sulfide-based electrocatalyst. A solid-state synthesis is employed to prepare the Cu9S5 catalyst for artificial N2 fixation in a neutral aqueous electrolyte. Despite an excellent NRR activity of 10.8 ± 0.4Author: Hee Soo Kim, Jihyun Choi, Jihyun Choi, Jimin Kong, Jimin Kong, Hansung Kim, Sung Jong Yoo, Sung Jong...

  • Thermodynamic Modeling of the NH3–CO2–H2O System with

    To facilitate simulation, design, and optimization of chilled ammonia processes for CO2 capture, we develop a thermodynamic model for the NH3–CO2–H2O system with the electrolyte NRTL activity coefficient model. The thermodynamic model explicitly accounts for the solution chemistry which includes dissociations of H2O, NH3, and CO2, formation of ammonium carbamate, and precipitation of

  • Isolation of a rice regeneration quantitative trait loci

    Aug 16, 2005Regeneration of plant organs is often the essential step in genetic transformation; however, the regeneration ability of a plant varies depending on the genetic background. By conventional crosses of low-regeneration rice strain Koshihikari with high-regeneration rice strain Kasalath, we identified some quantitative trait loci, which control the regeneration ability in rice.

Active regeneration begins when a small amount of fuel is introduced into the exhaust stream between the turbocharger and the DPF. This fuel is atomized into an extremely fine spray that does not burn.

  • CN101285412B - Excess NH3 storage control for SCR

    A method of regulating an amount of NH3 stored in a catalyst of an exhaust after-treatment system includes determining a mass of NH3 into the catalyst based on a dosing rate of a dosing agent that is injected into an exhaust stream upstream of the catalyst and determining a mass of NH3 out of the catalyst. An accumulated mass of NH3 within the catalyst is calculated based on the mass of NH3
