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 […]

June Heatwave: Microclimatic Observations from the Winterthur Network

If you stepped outside last week, you didn’t need a thermometer to tell you that summer had arrived. At the end of June, Switzerland experienced a historic heatwave, with over 40 meteorological stations across the country recording new temperature records for the month. Maximum daytime temperatures exceeded 38°C at several locations, and many regions experienced […]

Behind the Scenes: How We Prepare an Emission Measurement Campaign

In research, results are usually shared through papers, posters, or presentations. What often remains unseen is the extensive preparation behind an emissions measurement campaign. For our current project ADVISAR (ADdressing feasibility studies toward cleaner aVIation and environmental impacts research with SAf on unRegulated engines), we conducted emissions measurements with two different fuels at Stans Airport […]

Silvester Air Quality

During the Silvester fireworks in and around Zürich, many of you probably noticed that the air became foggy at some point. This can be explained by particles, emitted from the fireworks, accumulating in the boundary layer and acting as condensation nuclei for water droplets, which together with the air moisture and temperature led to fog […]

When Glass Ages: How a Self-Protecting “Gel” Makes Nuclear Waste Glass More Durable

How does borosilicate glass, the material used to lock away high-level radioactive waste, hold up after not just months, but decades in water? Our new study, led by the University of Montpellier and the French Alternative Energies and Atomic Energy Commission (CEA, Marcoule) tracks a simplified glass (CJ2) from 7 days to 27 years and […]

Stay Safe at Heights: The Importance of a Fall Protection Course

Working at heights carries significant risks, with falls being one of the leading causes of workplace injuries and fatalities. Whether in construction, maintenance, or installing measurement equipment in a test cell and generally in the industry requiring elevated work, proper training is essential for safety. A fall protection course provides crucial knowledge and hands-on training […]

Soot – vapor interactions in jet exhaust

Earlier on this blog, I introduced the objectives and planned methodology for our project on soot-vapor interactions in jet engine exhaust, which forms a core part of my Ph.D. work at METENIA and ETH. Since then, I’ve had the opportunity to present some of our first experimental findings at EGU25 (European Geosciences Union General Assembly […]

SPIN & 100 years of Fischer-Tropsch synthesis

On April 2, the Swiss Power-to-X Innovation Network SPIN celebrated a very special anniversary at its General Assembly: 100 years of Fischer-Tropsch synthesis. In 1925, chemists Franz Fischer and Hans Tropsch developed a process for converting carbon monoxide and hydrogen (synthesis gas) into long-chain hydrocarbons – an important step that today plays a central role […]
