Battery Research
Over 50 years ago, the sodium–sulfur battery was considered promising, but it failed to make its big breakthrough. Its poor performance at room temperature is a disadvantage. A Jülich development might now be able to solve this problem.
Climate Change
How can global warming be mitigated? Plant more trees, reflect more sunlight? Model calculations show what is most likely to benefit the climate.
The images taken with a scanning electron microscope show a high-tech composite material developed at the Jülich Institute of Plasma Physics: a fabric made of interwoven tungsten fibers in a tungsten matrix. The photos were taken by fusion and materials researcher Alexander Lau. He is analyzing and optimizing materials that could one day be used for the walls of nuclear fusion reactors. Image 1 won second prize of the "Participants Choice Award" at the Helmholtz Imaging Contest 2023.
