Researchers from NIES, ZHAW, Tokyo Metropolitan University retracted article on onion-like nanoparticles in aircraft exhaust; findings invalid

J. Edebeli, Autor bei Meteorology and Environment in Aviation

Regarding the retraction of an article due to analytical errors (July 29, 2026)

The authors have retracted the article, featured in this post, because the authors discovered critical errors in the experiments described in the article. Consequently, the research findings described in this post are no longer considered valid scientific knowledge. After the publication, the authors received comments at a scientific meeting that onion-like carbon particles might be […]

Onion-like nanoparticles found in aircraft exhaust

Summary: A research team from the National Institute for Environmental Studies, Zurich University of Applied Sciences, Tokyo Metropolitan University, and other institutions (hereinafter referred to as “our research team”) conducted emission tests on aircraft engines and examined the shapes and internal structures of the exhaust particles with high-resolution transmission electron microscopy. Our research team identified […]

Thank you for being a part of our community in 2024 and into 2025. While we completed several projects and project tasks in 2024, our work continues. Here are some major highlights to look out for in 2025: Schlagwörter: happy new year

Aircraft engine deterioration and emission performance (Ageing Aircrafts – AGEAIR)

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 […]

Aviation student project and bachelor thesis topics

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 […]

METENVIA updates her mission statement

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, […]

Studying the Interactions of Harmful Volatile Organic Compounds with Soot Particles using Dynamic Vapour Sorption

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 […]

Group retreat 2022 – redefining our mission

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 […]
