Coronavirus and the ITP

To combat the spread of COVID-19, the ITP staff is working mostly from home, visitors are limited, and teaching and seminars are online. For more information see https://www.uu.nl/en/information-coronavirus.

Liquid flow reversibly creates a macroscopic surface charge gradient

Liquid flow reversibly creates a macroscopic surface charge gradient

In 2014 scientists found that the interfacial chemistry of materials is altered when water is flown over them. The discovery that flow can alter chemistry at the atomic scale was a surprise for people in the field. While the observation was already published in Science in 2014, it was still unclear why flow alters chemistry. A collaboration between ITF and the Max-Planck institute in Mainz have now found the mechanism, which was recently published in Nature Communications.

The theory shows that the chemistry of even poorly soluble minerals is already altered at low flow rates, representative of rain filtering through soil. This means that the effect could potentially be common in nature. The result could thus be relevant for geological research, affecting soil decontamination and the transport of plant nutrients in farmland.

NWO Vidi Grant for Elisa Chisari

Elisa Chisari has been awarded an NWO-VIDI grant for her research proposal "Galaxy alignments answer fundamental questions about the Universe" With the 800k€ grant Chisari and her group will investigate the physics of galaxy alignments. Galaxies are sensitive to tides across the Universe, like the ones that make the oceans on the Earth rise. In this striking phenomenon, there is a wealth of information hiding about how our Universe began, what it is made of, and how galaxies were formed. In this project, researchers will help uncover this wealth of information.

Earlier this year, Chisari received another grant to collaborate with students on developing activities for the public to inform them about light pollution and its negative effects on biodiversity in the city and its surroundings.

NWO Vici Grant for Umut Gursoy

Umut Gursoy was awarded 1,5 million euros for his NWO-VICI proposal "The most archaic ocean in our universe." 

String theory suggests that waves in an ocean of quarks and gluons—the fundamental building blocks of atomic nuclei—are related to ripples on a black-hole horizon. Gursoy and his team will use this connection to describe how energy and charge flowed in our universe microseconds after the Big Bang.

NWO-ENW-Klein grant for developing black hole on a chip

Rembert Duine (UU & TU/e) and Reinoud Lavrijsen (TU/e) received an NWO-ENW-Klein grant of 700,000 euro for the proposal 'Black Holes on a Chip'. The goal of the proposed research is to use state-of-the-art materials science and nano-fabrication techniques to experimentally realise a magnetic analogue of astronomical black holes. The underlying theory was developed by Rembert Duine and published in 2017.
