  • Single atoms as catalysts

    Incorporating individual metal atoms into a surface in the right way allows their chemical behavior to be adapted. This makes new, better catalysts possible. They make our cars more environmentally friendly and they are indispensable for the chemical industry: catalysts make certain chemical reactio more

  • Thermodynamic Magic Enables Cooling without Energy Consumption

    Physicists at the University of Zurich have developed an amazingly simple device that allows heat to flow temporarily from a cold to a warm object without an external power supply. Intriguingly, the process initially appears to contradict the fundamental laws of physics. If you put a teapot of boil more

  • Description of rotating molecules made easy

    Feynman diagrams are a powerful tool in condensed matter physics. By turning highly complex equations into sets of simple diagrams, the method has established itself as one of the sharpest tools in a theoretical physicist’s toolbox. Giacomo Bighin, a postdoc in the group of Mikhail Lemeshko at the I more

When Water Levitates

Have you ever seen a drop of water navigate a maze? It’s possible thanks to a weird phenomenon called the Leidenfrost Effect. Understanding Leidenfrost — first described more than 200 years ago — helped engineers make more efficient steam engines. Today, scientists are using high-speed cameras t ... more

The Science of Fireworks!

Professor Chris Bishop, presenter of the 2008 Royal Institution Christmas Lectures, gives a family lecture on the history of the modern firework.Through demonstrations of pyrotechnic chemistry hear how Chinese incendiaries made from honey led to the development of gunpowder; discover how the lou ... more

The creation of tools made from laser light

After the Nobel Prize for Physiology or Medicine has been awarded, it is physics' turn. The 2018 Nobel Prize in Physics was awarded to Arthur Ashkin, Gérard Morou and Donna Strickland for their pioneering innovations in the field of laser physics. Strickland is only the third woman to receive the No more

Detecting gravitational waves from black hole collisions

This year’s second Nobel Prize in the sciences was awarded today. The prize for physics was awarded to researchers who contributed to the observation of gravitational waves, ripples in space-time that were originally created by colliding black holes over a billion years ago. more

The History of the Atom

All matter is made up of atoms. This is something we now take as a given, and one of the things you learn right back at the beginning of high school or secondary school chemistry classes. Despite this, our ideas about what an atom is are surprisingly recent: as little as one hundred years ago, scien more

  • Prof. Dr. Joachim H. Ullrich

    Joachim Ullrich, born in 1956, studied geophysics and physics at the University of Frankfurt where, after graduating in 1983, he also completed his doctorate in 1987 and qualified as a professor in 1994. From 1989 to 1997 he worked as a research assistant at the Gesellschaft für Schwerionenforschung more

  • Dr. Jens Simon

    Jens Simon, born in 1962, has followed two academic paths as he moved between Braunschweig, Jülich and Cologne. One path led to a doctorate at the Technical University of Braunschweig in German linguistics on the language of the author Arno Schmidt. The other path led to a doctorate at the Universit more

  • Dr. Horst Bettin

    Horst Bettin, born in 1955, studied physics at the Technical University of Braunschweig where he completed his PhD at the Institute for Semiconductor Physics and Optics. In 1990 he joined the Physikalisch-Technische Bundesanstalt and focused his research mainly on density measurements. He has also b more
