Germany finds truckers cheating to hide emissions

German authorities have identified hundreds of trucks "manipulated" to save their operators money by shutting off exhaust treatment systems, saying many more cheating vehicles could be at large on Europe's roads.

Edges and corners increase efficiency of catalytic converters

Catalytic converters for cleaning exhaust emissions are more efficient when they use nanoparticles with many edges. This is one of the findings of a study carried out at DESY's X-ray source PETRA III. A team of scientists ...

Researchers convert CO to CO2 with a single metal atom

Researchers from Washington State University and Tufts University have demonstrated for the first time that a single metal atom can act as a catalyst in converting carbon monoxide into carbon dioxide, a chemical reaction ...

Microwaves against cold-start emissions

During cold start, a car engine emits far more particulate matter and other pollutants than during warm conditions. This is because a cold catalytic converter is much less efficient at low exhaust gas temperatures. So what's ...

Researchers study the surfaces of ceria nanoparticles

At Karlsruhe Institute of Technology (KIT), scientists have studied ceria nanoparticles with the help of probe molecules and a complex ultrahigh vacuum-infrared measurement system and obtained new insights into their surface ...
