  1. 1. Lean NOx reduction by alternative fuels - with focus on catalysts for dimethyl ether

    Författare :Sara U Erkfeldt; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biofuel; In2O3; lean NOx reduction; alumina; Cu-ZSM-5; Ga2O3; DME; hydrocarbon-SCR; alternative fuel; NOx storage; B2O3; Ag Al2O3;

    Sammanfattning : There is an increased demand for diesel engines running on non-fossil fuels such as dimethyl ether (DME), biodiesel and synthetic diesel. DME is a promising alternative fuel with potential for high energy efficiency and low CO2 emissions. However, during all high temperature combustion NOx is formed, which may require exhaust aftertreatment. LÄS MER

  2. 2. Thermal conductivity of AlXGa1-XN and β-Ga2O3 semiconductors

    Författare :Dat Tran; Plamen Paskov; Vanya Darakchieva; Mattias Thorshell; Linköpings universitet; []

    Sammanfattning : For the high-power (HP) electronic applications the existing Si-based devices have reached the performance limits governed by the material properties. Hence the device innovation itself is unable to enhance the overall performance. LÄS MER
