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 ...

Dynamic catalytic converters for clean air in the city

Reducing pollutant emission of vehicles and meeting stricter exhaust gas standards are major challenges when developing catalytic converters. A new concept might help to efficiently treat exhaust gases after the cold start ...

Nanocatalysts improve processes for the petrochemical industry

With the goal of advancing the oil, mining and energy industries, as well as counteracting the emission of greenhouse gases, nanotechnologist Hector Barron Escobar designs more efficient and profitable nanomaterials.

Insights into catalytic converters

Modern catalytic converters for the treatment of exhaust gases in vehicles with a combustion engine have largely contributed to reducing of pollutant emissions. By oxidation or reduction, i.e. the donation or acceptance of ...
