Completely Elastic Deformation of Hydrogenated Ta Thin Films

Nanostructured metal hydrides could play a key role in a hydrogen economy. The nanostructuring or confinement of these materials as, e.g., thin films significantly affects the structural and functional properties. For tantalum hydride, a versatile hydrogen sensing material, we show that the confinement of tantalum as a thin film extends the...

Suppression of the Phase Coexistence of the fcc-fct Transition in Hafnium-Hydride Thin Films

Metal hydrides may play a paramount role in a future hydrogen economy. While most applications are based on nanostructured and confined materials, studies considering the structural response of these materials to hydrogen concentrate on bulk material. Here, using in situ in- and out-of-plane X-ray diffraction and reflectometry, we study the fcc ...

Metal Hydride Based Optical Hydrogen Sensors

Hydrogen is playing a key role in the transition to a sustainable economy and in a variety of industrial processes. For its safe handling, the detection of hydrogen in a fast, reliable and accurate manner is crucial. Thin film metal hydride based optical hydrogen sensors provide an attractive option to sense hydrogen in a variety of conditions...
