International Water Day: research on water at Fysikum

The UN General Assembly started the initiative in 1992 and since then, different water-related themes have been highlighted every year. In Sweden, World Water Day is coordinated by the Swedish Hydrological Council (SHR) and has been celebrated since 2006. At Fysikum, we tell you about our research on water during this day.

Martin Beye is researching on catalysts working against the climate change

“In the past, we developed many new and powerful techniques with x-ray radiation. The time is ripe now to use them for something important”, says Martin Beye. Climate change is the most important topic to be addressed in the world for the coming decades. Martin commits to make his contribution working at Stockholm University, after his start at Fysikum in September 2023. “At Stockholm University, there is a unique environment, knowledge and infrastructure and wonderful colleagues – all that is required to actually make an impact."

Professor Anders Nilsson receives the 2024 Plyler Prize for Molecular Spectroscopy & Dynamics

This prize recognizes notable contributions to the field of molecular spectroscopy and dynamics. The prize consists of $10,000, an allowance for travel expenses, up to $1000, to attend the meeting at which the prize is to be presented and a certificate citing the contributions made by the recipient. The motivation is “for seminal contributions in the application of x-ray spectroscopy methods to the molecular dynamics of water and catalytic reactions.”

Conversion of carbon dioxide back into fuels

The conversion of carbon dioxide back into fuels via electrochemistry is a very attractive alternative. - In my studies, I am developing the essential understanding of these reactions by following time-resolved transformation at the atomic and molecular level, says Sergey Koroidov.

The importance of water and fuel cells in society

When he was in secondary school, he was mostly interested in chemistry and physics. He continued with this focus during the 4-year technical program and during studies abroad. Since then, Professor Anders Nilsson has worked in several countries and his list of publications and awards is long.

Importance of Quantum Effects in Water

Using ultrafast electron diffraction, Anders Nilsson at Stockholm University have participated in a study lead by colleagues at SLAC National Accelerator Laboratory in California on how the structure of water changes after a fast change in the quantum distribution of distances in the internal bond. Upon increasing the quantum number by one unit of the internal OH stretch the team surprisingly found that the hydrogen bond becomes strengthen. The finding is published this week in Nature.

Liquid-liquid phase separation in supercooled water from ultrafast heating of low-density amorphous

Recent experiments continue to find evidence for a liquid-liquid phase transition (LLPT) in supercooled water, which would unify our understanding of the anomalous properties of liquid water and amorphous ice. These experiments are challenging because the proposed LLPT occurs under extreme metastable conditions where the liquid freezes to a crystal on a very short time scale.
