6. Catalytic formation of ammonia from nitric oxide
Abstract : The emission of nitrogen oxides (NOx) from automobiles results in severe environmental and biological effects. Passive selective catalytic reduction (passive SCR) of NOx with ammonia (NH3) is a proposed method for abatement of NOx emissions in net lean-burn gasoline passenger vehicles. READ MORE

8. Steam Cracking of Polyolefins in Fluidized Bed Systems: Influences of the Bed Materials on the Hydrogen Transfer Reactions
Abstract : Plastic materials are crucial to the supply of everyday necessities, such as clothes, packaging, and building materials. Most plastic materials are disposed of after a short period of use due to their low cost of production. The linear use of plastics has resulted in high levels of plastic waste materials. READ MORE

9. CO2 activation for methanol synthesis on copper and indium oxide surfaces
Abstract : Catalytic recycling of CO2 to added-value chemicals, such as methanol (CH3OH), has been proposed as a possible way for sustainable production of fuel and chemicals, in addition to providing a route to mitigate climate change. Multiple systems are known to be active for the conversion of CO2 to methanol, and the state of the art catalyst is Cu/ZnO/Al2O3. READ MORE

10. ALTERNATIVE POLYETHYLENE CROSSLINKING CONCEPTS FOR POWER CABLE INSULATION
Abstract : We currently witness an accelerating shift from fossil energy sources to renewables driven by the urgent need to reduce carbon emissions. Wind, solar and hydro power is most abundant in places far away from the end user, which necessitates the efficient transport of electricity over long distances. READ MORE
