  Kinetics made easy: Fast and accurate analysis of gas-producing reactions par Pr. Gadi ROTHENBERG

  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, for understanding reaction mechanisms, and for designing and optimizing chemical processes.[1] But the task
  itself is often boring, time-consuming, and labour-intensive. This is especially true when you're determining Arrhenius relations, which require multiple sets of measurements.
  We have now developed a new and simple device for measuring the kinetics of gasproducing
  reactions.[2] This benchtop device costs <€250 and weighs <2kg, yet gives accurate
  reaction profiles with >3000 measurements. It is also programmable for running 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.

  Gadi Rothenberg received his PhD in Applied Chemistry summa cum laude from the Hebrew University of Jerusalem in 1999. After two years as a Marie Curie Fellow at the University of York, he moved to the University of Amsterdam. Since 2008 he is Professor and Chair of Heterogeneous Catalysis and Sustainable Chemistry. Rothenberg
  teaches courses on catalysis and workshops on scientific writing and innovation. He has published two books and over 200 papers in peer-reviewed journals. He also invented 16 patents, and cofounded
  the companies Sorbisense, Yellow Diesel and Plantics. In 2017 he was Senior Visiting Scholar at Fudan University, and in 2018 he was the Lady Davis Visiting Professor at the Hebrew University.
  Since January 2020 he is also the Technical Director CO2 and Circular Economy of the Shanghai Institute for CleanTech Innovation
