Zirconium (Zr) alloys are widely used in nuclear power plants as fuel cladding and are susceptible to hydrogen (H) degradation. For long operational service, Zr-based components can suffer a mechanism known as Delayed Hydride Cracking (DHC) associated to an increase of the crack propagation velocity by the re-orientation and precipitation of Zr hydride. [...]

Delayed Hydride Cracking (DHC) is a failure mechanism that occurs in Zr alloysunder certain conditions of hydrogen concentration, temperature and stress gradient. In service,hydrogen produced by corrosion reaction can be incorporated in Zr alloys and if the solidsolubility is exceeded, hydrogen precipitates as zirconium hydride. [...]

To meet the ever-increasing user demand, eleven of the fifteen European Spallation Source (ESS)instruments under construction aim to offer polarised neutrons for user experiments. They include animaging instrument, a SANS instruments, two reflectometers, three diffractometers, and four spectrometers.In conjunction with in-kind contributions and instrumentation grants, the ESS Polarisation Project willsupport the incorporation of polarisation analysis on eight of the eleven instruments. [...]

Significant advancements in perovskite solar cells (PSCs) have been driven by the engineering of the interface between perovskite absorbers and charge transport layers. Inverted PSCs offer substantial potential with their high power conversion efficiency (PCE) and enhanced compatibility for tandem solar cell applications. [...]

Polarized neutron imaging brings the great advantage of analyzing bulk magnetic properties with good spatial resolution. The technique is based on the interaction of the neutron spin with magnetic samples or free magnetic fields and observing the changes to a spin-polarized neutron beam. [...]
