Rare earth magnets are widely used in a range of gadgets, instrumentation and even toys but recycling the mixtures of metals from which the magnets are formed is difficult. Now, research published in the journal Angewandte Chemie offers a novel approach to the isolation of neodymium and dysprosium from dismantled magnets. The technique could ward off a future shortage of these metals.

Fourier transform is the data processing naturally associated to most NMR experiments. Notable exceptions are Pulse Field Gradient and relaxation analysis, the structure of which is only partially suitable for FT. With the revamp of NMR of complex mixtures, fueled by analytical challenges such as metabolomics, alternative and more apt...

The development of non-uniform sampling (NUS) strategies permits to obtain high-dimensional spectra with increased resolution in significantly reduced experimental time. We extended a previously proposed signal separation algorithm (SSA) to process sparse four-dimensional NMR data. It is employed for two experiments...
