Two-dimensional Nanomaterials

Stacking of 2-dimensional nanomaterials offer state-of-the-art performance metrics. Novel, high-throughput techniques to realize ultra-clean, dry-transferred 2D material heterostructure are highly sought-after to enable advanced material technologies.

In this project, we explore a novel approach to perform microfabrication of clean, 2D material heterostructure to enable high performance graphene-based sensor applications. We perform CVD synthesis of graphene films and their quality characterization using Raman spectroscopy. Using chemical vapor deposition (CVD), the mass-production of graphene films for industrial applications is achievable today. Current progress in standardization of graphene & 2D material quality is encouraging for the development of industrial applications using graphene films. Several type of graphene-based use case applications are explored during the project.

Finding and blocking infection routes in hospitals

Digital epidemiologist Onicio Batista Leal Neto standing in front of an ETH building with his arms folded.

During the COVID-19 pandemic, hospitals often became hubs of infection. Researchers from ETH Zurich, EPFL and the ISI Foundation are developing a wearable tracking system for healthcare facilities that can identify the risks of infections. Initial tests in Switzerland and Africa show its potential.

Acids help against airborne viruses

Man coughing, aerosol particles floating in the air in front of him

A new study by various Swiss universities shows that aerosols in indoor air can vary in acidity. This acidity determines how long viruses remain infectious in the air – with profound implications for virus transmission and strategies to contain it.

Preparing for future coronavirus variants using artificial intelligence

Illustration of the detail view of coronaviruses.

Researchers at ETH Zurich have developed a method to explore the possibilities of how the pandemic virus could evolve. Thanks to their work, it may be possible to develop antibody therapies and vaccines that are more likely to be effective also against future viral variants.
