A group of researchers from Far Eastern Federal University (FEFU), Austria, Turkey, Switzerland, and the UK has developed a new metallic glass that is 85% more efficient in oxidizing methanol than its platinum-based analogs. Currently, the efficiency factor of such cells varies from 40% to 60% (while that of a gasoline engine is only 20-30%).

Based on a three-year study of toxic and environmentally relevant pollutants from gasoline direct injection (GDI) engines, Swiss researchers have concluded that some GDI engines emit just as many soot particles as unfiltered diesel cars did in the past. Further, the GDI particles carry numerous carcinogenic substances. Click to enlarge.

A recent PSI study led by environmental scientist Christian Bauer found that a battery electric car is already the most environmentally friendly option in Switzerland and many other countries, even when the manufacture of the battery is figured in. Note the large impact of energy storage in the latter.

The study by the team led by researchers from the Laboratory of Atmospheric Chemistry, Paul Scherrer Institute, Switzerland, appears in the journal Nature Communications. Chemical analysis of the emissions shows that SOA is mainly produced via photo-oxidation of aromatic VOCs, present in gasoline, from the exhaust.

A new study by an international team led by researchers from the Paul Scherrer Institute (PSI) in Switzerland has found that modern diesel passenger cars equipped with diesel particulate filters (DPFs) emit fewer carbonaceous particulates than gasoline-powered vehicles. times more SOA than POA after 5–10 hours of atmospheric aging.
