H in thin films: size and stress effects on the system thermodynamics and kinetics

MPIE Colloquium
Due to its high diffusivity hydrogen atoms alloy with metals even at room temperature. At this temperature, the materials microstructure remains rather stable. When the system size is reduced to the nano-scale, microstructural defects as well as mechanical stress significantly affect the ... [more]

Sustainability and raw materials: do we have them enough?

Materials play a crucial role in driving the twin transition, a key strategy of the European Union to address current and future environmental challenges. Currently, improving the efficiency of solar cells and the capacity of battery storage is essential for achieving a Net Zero Carbon society ... [more]

Constant strain rate nanoindentation up to 10,000 s-1 for reliable extraction of mechanical properties and activation parameters

The use of nanoindentation-based techniques to study high strain rate deformation behavior of materials is of immense scientific interest because it enables investigating the strain rate dependence of individual grains and small-scale structures. While nanoindentation impact tests, capable of ... [more]

Refractory alloys and composites - pathways to improved performance

Refractory metals and their alloys are considered a versatile group of high temperature resistant materials. Promising design approaches to extend their application range include the modification of both existing commercial materials, but also novel alloys that are still at earlier stages of ... [more]

Strengthening and Toughening Mechanisms in Metal-Graphene Nanolayered Composites

Nanoscale metal-graphene nanolayered composites are known to have ultra-high strength due to the ability of graphene to effectively block dislocations from penetrating through the metal-graphene interface. The same graphene interface can deflect generated cracks, thereby serving as a toughening ... [more]

Deuterium retention studies in displacement damaged tungsten in order to gain understanding of the phenomena involved to predict fuel retention in future devices

In the search for new energy sources, nuclear fusion of deuterium and tritium is one of the most promising options for human kind. However, thermonuclear fusion has set an enormous challenge to theory, experiment and technology due to the harsh environment that will take place in a future nuclear ... [more]

New in-situ and operando techniques for correlative microscopy and chemical imaging : Case studies in mapping hydrogen and other low-Z elements in energy materials

Development of innovative characterization tools is of paramount importance to advance the frontiers of science and technology in nearly all areas of research. In order to overcome the limitations of individual techniques, correlative microscopy has been recognized as a powerful approach to obtain ... [more]
