Research

JCNS-3 utilises and develops various neutron and complementary X-ray methods to investigate energy materials and energy technology systems in-situ and operando.

Nanostructured Interfaces

Nanostructured interfaces are of great importance in various applications, e.g. in batteries and electrolytes, fuel cells or heterogeneous catalysis. Restructuring occurs almost universally on both sides of the interfaces, typically over 3 to 5 atomic or molecular layers. This restructuring influences both the structure and the dynamics on both sides of the interface, which in turn change the physicochemical properties and thus the applications. Bulk materials can also exhibit nanostructured defects and restructuring, which need to be fully understood.

We use various scattering methods to characterise short- and long-range (mis)ordering, in particular the pair distribution function method. To investigate dynamic processes such as the diffusion of ions/protons and molecules through materials or on surfaces, we use, for example, quasielastic neutron scattering.

Ion Mobility

The project aims at studying the impact of lattice dynamics and oxygen ordering on the amplification of oxygen mobility at low temperature in the non stochiometric K2NiF4-type Ruddlesden-Popper phases.
