Recent Progress in Liquid State Electrochemistry Coupled with NMR Spectroscopy
ChemElectroChem, 2021 AbstractAnalytical methods of electrochemistry (EC) are relatively inexpensive, and widely used in science, industry, and medicine. Although EC is distinguished by its high sensitivity, it does not provide direct and detailed data about the bond connectivity or dynamics of the molecular system.

Emergent Spin‐Glass Behavior in an Iron(II)‐Based Metal–Organic Framework Glass
Advanced Functional Materials, EarlyView.A one‐pot, solvent‐free synthesis yields an Fe2+‐based metal‐organic framework (MOF) glass featuring a continuous random network structure. The material exhibits spin‐glass freezing at 14 K, driven by topological‐disorder and short‐range magnetic frustration, showcasing the potential of MOF glasses as a plattform for cooperative magnetic phenomena in ...

Using error correction to determine the noise model
, 2007 Quantum error correcting codes have been shown to have the ability of making quantum information resilient against noise. Here we show that we can use quantum error correcting codes as diagnostics to characterise noise. The experiment is based on a three-
