With high-performance computing and machine learning towards the new generation of carbon-free combustion chamber systems

Over 80 percent of the energy consumed worldwide is generated through combustion processes. According to current knowledge, this value will change little in the medium term. Combustion processes, which occur in industrial blast furnaces, household burners, carrier rockets, gas turbines, and engines…

ERIS is to include, on the one hand, technology centers for robotics and In-Situ Resource Utilization (see text). These include a large simulator for planetary surfaces, capable of generating temperatures of +/- 150 degrees Celsius, a robotics testing hall, and an outdoor testing area. The third technology center,

The ERIS Large Research Center is to be established in the Saxon Lusatia or in the Central German mining region. In addition to scientific buildings, an innovative residential park, as well as a Spacetech industrial park and a Greentech industrial park, are also planned nearby.

Optical excitation in the solid with subsequent interference of the photoemitted electrons. Below are the orbitals whose orientation with respect to the atomic positions (small white spheres) is responsible for the orientation of the transition dipole moments. The curves illustrate the optical excitations incident from above through two crossed pulses. Above that is the shape of the expected experimental measurement signal. (Photo: Nature Communications)

When light hits matter: Kaiserslautern researchers visualize the efficiency of optical excitation in solids

The interaction of light and matter is responsible, for example, for plants conducting photosynthesis and solar cells generating electricity. The efficiency of light absorption in matter is determined on a microscopic scale by so-called transition dipole moments. The research group of Prof. Dr. Mart…
