In the present study, a global kinetic model of three-way-catalyst-coated gasoline particulate filters was developed to understand relevant mechanisms taking place both in clean and real soot-loaded filters. The involves reaction rate expressions for CO, C2H4, C7H8 conversion over Pd/CeZr/Al2O3 catalyst, hydrothermally treated at 650 °C. Particularly, new expression proposed ethylene based on d...

Particulate matter of vehicle exhaust is known to contain carcinogenic compounds such as polycyclic aromatic hydrocarbons (PAH) and is suggested to increase lung cancer risk in humans. This study examines the differences in diesel and gasoline-derived PAH binding to DNA in a human bronchial epithelial cell line (BEAS-2B). Particulate matter (PM) of gasoline exhaust was collected from passenger ...

Abstract Diesel particulate filters is the most effective post-treatment device used to reduce diesel exhaust emissions. As amount of matter captured in filter continues increase, pressure engine gradually increases, thereby affecting power performance engine. Therefore, when capture reaches a certain value, needs be regenerated. Regeneration will produce secondary pollution, which CO one impor...

BACKGROUND We frequently fail to identify articles relevant to the subject of acute kidney injury (AKI) when searching the large bibliographic databases such as PubMed, Ovid Medline or Embase. To address this issue, we used computer automation to create information search filters to better identify articles relevant to AKI in these databases. METHODS We first manually reviewed a sample of 22 ...
