influencerait en effet la définition d'une frontière entre l'intérieur des planètes et leur atmosphère. Cela aurait un impact sur les propriétés planétaires telles que la conductivité thermique et d'autres

uses neutron tomography to seek clarity on the problematic areas where Lithium gets stuck inside cells. The objective is to develop high-performing batteries in the future. Lübcke's project receives support
