Hydrogen is nowadays viewed as a key element for developing low-carbon energies, but it diffuses in metals and alloys and segregates in crystalline defects, reducing the ductility of the material. This phenomenon is well-known and called hydrogen embrittlement (HE). In this work, we aim to reduce the negative impact of hydrogen by adding boron at interfaces to improve the resistance against...
Scanning Kelvin Probe (SKP) techniques have now been in use for mapping hydrogen in materials for about a decade. Different from techniques such as Secondary Ion Mass Spectroscopy (SIMS) or Atom Probe Tomography (APT) they do not measure the hydrogen concentration at a certain site, but rather the local activity. In time-resolved experiments they can provide information about how much hydrogen...
Understanding the effects of hydrogen in materials became a pressing topic with the imminent shift towards green technologies and the adoption of hydrogen as energy carrier. It is expected that the use of hydrogen will increase in all industries, together with the need for safe transport and storage and consequently the development of new materials and technologies to cope with it. A critical...
The NanoSIMS is emerging as a powerful tool to study complex problems in materials science and, along with atom probe tomography, is one of the few techniques able to localise hydrogen and deuterium at microstructurally relevant length scales. The NanoSIMS is a high-resolution secondary ion mass spectrometry instrument capable of chemical mapping at <100 nm spatial resolution, detection limits...
