26th ETH Nanoparticles Conference

June 20-22, 2023
ETH Zurich, Switzerland (in-person event)

Focus Event: Indoor air filtration of biogenic and combustion nanoparticles

Conference Website and Registration:

The Nanoparticle Conference in 2023 (#ethnpc23) is organized as an on-site conference at the ETH Zürich. It serves as an interdisciplinary platform for expert discussions on all aspects of nanoparticles, freshly emitted from various sources, transformed in ambient air, distributed on local and global scale, on technical mitigation aspects, particle legislation, and impact of particles on health, environment, and climate. The conference brings together representatives from research, industry, and legislation.

Conference Topics

  • Aircraft, marine and other non-road sources
  • Ambient air particles, secondary pollutants
  • Biomass-, biofuel- and synfuel combustion
  • Brake- and tyre-wear, non-combustion emissions
  • Emission control of combustion engines
  • Environmental effects
  • Filtration of combustion and biogenic nanoparticles
  • Health effects
  • Impact on climate
  • Indoor particles
  • Legislation and enforcement
  • Nanoparticle formation and transformation
  • Nanoparticle metrology and chemical characterization
  • Nanoparticle chemistry and toxicology
  • Occupational exposure and prevention
  • Periodical technical inspection for in-use vehicles

Focus Event:
Indoor air filtration of biogenic and combustion nanoparticles

The outbreak of the COVID pandemic taught us that viruses indeed are nanoparticles, which travel with aerosols, similar to combustion-generated nanoparticles. Both classes of particles are mainly taken up by inhalation. The translocation of sub-200 nm particles through the alveolar membrane and the distribution in the body show similarities too. The formation and release of such particles are quite different. However, their dimensions are similar and the abatement of biogenic nanoparticles can be achieved using similar filtration principles and technologies that have been applied successfully for combustion engines. These aspects will be discussed in the 2023 focus event.

Health Session

The session will provide new experimental and epidemiological results about health consequences of combustion emissions. Special emphasis will be given to effects of nanoparticles on children's health.

Papers and Posters

We invite you to submit abstracts for oral and poster presentations on the conference website,

  • Abstracts must contain new information and results related to the aforementioned topics.
  • Best poster presentations will be awarded with prize money and certificates.
  • Presenters at the conference will be invited to submit full length papers for publication after peer-review, in the journal "Emission Control Science and Technology".
  • All contributions (including pdf and mp4 video files of talks, posters, and abstracts) will be published on the conference website.
    Submission of an abstract includes your agreement for publication on the conference website.
