If you have ever owned a car, you are probably familiar with the mandatory (bi-) annual emissions test, which were introduced to ensure that wear and tear on the engines do not have a negative impact on the exhaust gas quality. And even if you have never owned a car, chances are that this connection […]
Are you looking for a student project or bachelor thesis (ZHAW Students) or a master thesis topic (ZHAW and non-ZHAW students)? In the table below, we present the current topics we have to offer. This is not an exclusive list and will be regularly updated, take a look. We also welcome spontaneous requests for thesis […]
Our Mission We are a group of highly driven aeronautical engineers, chemists, and atmospheric and environmental scientists, forming an interdisciplinary team who are interested in aircraft engine emissions and their influence on both local and global air quality. Our aim is to improve our understanding of the interplay between aircraft emissions, the environment, and human […]
The International Civil Aviation Organization (ICAO) requires that engines of maximum rated thrust greater than 26.7kN be certified for their emission performance[1]. For certification, ICAO defined four power modes in an aircraft’s landing-take-off (LTO) cycle as emission test points. These modes include idle/taxi at 7% of the maximum rated thrust (Foo), approach at 30% Foo, […]

Written by: Jon G. Bell (belj@zhaw.ch) Volatile organic compounds (VOCs), such as benzene and formaldehyde, are characterised by high vapour pressures and, therefore, can easily adsorb to the surface of airborne soot particles, accumulating at the vapour-solid soot interface, within pores, or between the carbon core turbostratic graphene layers. These VOC-loaded, nanometric particles are extremely […]
After a year of executing our previous goals and strategies and changes in personnel, the present METENVIA team embarked on a journey away from the noise of the city for a quick internal assessment and renewal, a retreat. During this period at Herzberg in Aargau, Switzerland, we evaluated and renewed our focus, strategy, and drive […]
Written by: Thomas Rötger On 7 October 2022, at the end of 2 weeks of negotiations during the 41st ICAO Assembly, the 193 ICAO Member States took the historic decision to adopt a collective long-term global aspirational goal (LTAG) of net-zero carbon emissions of international aviation by 2050. This resolution was based upon a report on the […]
We introduced you to the concept of lung deposited surface area (LDSA) and our network of LDSA sensors in a previous post. The idea of monitoring very fine particulate matter (PM) comes from the knowledge that up to 90% of number concentration of ambient PM comprises of particles less than 500 nm of which ultrafine […]
Written by Manuel Roth The Center for Aviation is characterized by multidisciplinary research and services within the aviation sector. The versatility of these focal points inspires and shapes my everyday life. But let’s start at the beginning. As a scientific assistant, I work for the Center’s Human Factors Team in addition to the MetEnviA team. […]
