Detection of single photons boosted the development of quantum information processing, as well as finding a wide range of applications in astronomy, sensing, metrology, LiDAR, and biosensing technologies.(1) Single photon detectors (SPDs) require high quantum efficiency (>90%), low dark count rates, and ultra-fast response. State of the art superconducting nanowire SPD (SNSPD) can deliver superior […] >>

Sodium-ion batteries can compete with Li-ion batteries for power applications, while being free of critical metals such as Co, Ni or Li. However, fast charging can lead to inter- and/or intra-particle reaction heterogeneities causing underutilisation of the electrode and/or mechanical degradation involving particle cracking. These complex non-equilibrium processes can have profound effects on the overall […] >>

The in situ characterization of battery materials is needed to help designing safer and more efficient electrochemical devices. In particular, following in real-time the lithiation and ageing mechanisms require to use advanced non-destructive tools capable to probe the system during cycling. In this regard, synchrotron and neutron techniques provide unique capabilities to access the chemical, […] >>
