Un modello del catalizzatore a base di zeolite: le sfere nere rappresentano gli atomi di silicio o di alluminio (c'è un atomo di alluminio per ogni 9 atomi di silicio circa), mentre i pezzi di collegamento trasparenti contengono ciascuno un atomo di ossigeno come ponte

Insieme, i tre formano una struttura complessa ma regolare con pori di diverse dimensioni. © Istituto Paul Scherrer PSI/Mahir Dzambegovic

Study reveals: Smoke from crop residue burning worsens air pollution in Indian cities

Identifying the main source of air pollution in Indian cities is crucial to reducing the many deaths caused by fine particulate matter (PM₂.₅) – deaths that during the harvest season can account for up to half of all air pollution-related fatalities. An international research team lead by the Paul Scherrer Institute (PSI), funded by the Swiss Agency for Development and Cooperation (SDC) has investigated in detail the sources of the organic components of fine particulate matter in the northern Indian cities of Delhi and Kanpur, located in the Indo-Gangetic Plain. Using novel high-resolution molecular measurement techniques and advanced data analysis, the researchers were able to precisely identify and quantify the sources of organic fine particulate matter.

Advancing Biogas Quality: Tackling Siloxane Challenges for Smooth Energy Transition

Siloxanes, present in everyday items, can compromise the efficiency and durability of bioenergy systems, even at trace levels. Monitoring and quantifying these impurities are critical for improving biogas quality and expanding its role in renewable energy. However, sampling biogas and storing samples containing siloxanes for analysis remain a significant challenge.

On the afternoon of 28 May 2025, our annual Energy Briefing took place at the Zentrum Paul Klee in Bern - for the fourth time! This year, everything revolved around the topic of ‘electromobility’.

The event brought together researchers, industry experts, and political decision-makers to discuss the crucial role of electromobility for a sustainable future.

Our speakers, Martin Bolliger (TCS), Prof Dr Sarbajit Banerjee (PSI/ETH Zurich) and Adrian Wachholz (ABB E-mobility), offered exciting insights and engaged in lively discussions with the audience on questions such as:

  • How can we scale renewable energy infrastructure to meet the demands of electric vehicles?
  • What solutions are there for creating sustainable and resilient supply chains for critical raw materials needed for battery technologies?
  • Can innovations such as bidirectional charging overcome regulatory and technical barriers?
