Webinar by Prof. Gadi Rothenberg from University of Amsterdam

"Back to Arrhenius: Understanding the pre-exponential factor in surface reactions"

Abstract: Measuring the kinetics of chemical reactions is common in many labs. You probably did it yourself many times. Knowing the kinetics gives insight into systems as they move towards equilibrium. It's essential for testing hypotheses, understanding mechanisms, and designing and optimizing chemical processes. But the task itself is often boring, time-consuming, and labour-intensive. This is especially true when studying Arrhenius relations, which require multiple sets of measurements. 
We have now developed a simple device for measuring the kinetics of gas-producing reactions. This device costs <€250 and weighs <2 kg, yet gives accurate reaction profiles with >3000 measurements. It can also run temperature profiles, giving Arrhenius plots with hundreds of data points from a single experiment. In the lecture, I will explain the working principles of this device,[3] and show how you can build one yourself. Then, I will show how these measurements can help us understand the fundamentals of catalytic reactions on surfaces, explaining the empirical observations that Arrhenius made in Uppsala in the 1880-s. 

The webinar is open to everyone.

Previous news and events

Haining Tian doubly awarded in 2019 and 2020

 Haining Tian  was awarded the prestigious Göran Gustafsson Prize in 2020, and also was awarded Wallenberg Academy Fellow in Engineering and Technology 2019, for his work on catalysis and solar fuels.

Read more about Haining at the Knut and Alice Wallenberg Foundation webpage, and on the Tian group webpage.

Shedding new light on greener synthesis pathways

In October 2019, Sascha Ott, Eszter Borbas, Leif Hammarström and Jacinto Sá, received a 5-year grant of 35 million kronor from the Knut and Alice Wallenberg Foundation, for their interdisciplinary project "Unexplored Approaches to Organic Photoredox Catalysis

In this new research project, the groups will focus on finding new alternatives to several reactions that are widely used in the chemical industry at present. The project objective is to develop new synthesis pathways that generate less waste, or new synthetic routes that have not been practicable before.

CAP scientists in the TV news

At the CAP meeting in Umeå, March 4, 2019, CAP researchers were discussing future hydrogen technology. We also had the chance to test drive a fuel cell vehicle that runs on hydrogen gas. Swedish public service television filmed the event, which can be watched here: Vätgasbilar spås ha nyckelroll i framtiden


The First European Congress on Photosynthesis Research was a success!

Over 400 delegates from Europe, and all over the world, discussed recent findings in natural and artificial photosynthesison June 25 - 28, 2018. To see what it was all about, go to the conference homepage: ePS1.org

One of our prominent invited speakers, Junko Yano from Lawrence Berkeley National Laboratory, was interviewed in Swedish national radio. You can listen to the program here (mostly in Swedish).


The CAP workshop 2018

Our annual workshop was held at Sigtunahöjden in Sigtuna, on April 26-27. Thanks for all the interesting presentations everyone, you made the workshop great!
