Detection of low-lying atomic states in actinium

Two lowest-energy odd-parity atomic levels of the radioactive element actinium were observed in a laser-spectroscopy experiment at the Johannes Gutenberg University in Mainz, Germany, resolving a long-standing puzzle of “missing” atomic states predicted by theory. The properties of these states (exact energies, lifetime, and hyperfine structure) were studied by the experimental team and found to […]

Zero‐field NMR in metal containers

High field (HF) NMR is regularly used for chemical reaction monitoring, which has tremendous applications in industry, biology and medicine. In zero- to ultralow-field (ZULF) NMR we perform an unorthodox type of NMR experiment which does not require the usual large magnetic field. In high field NMR, observing complex media inevitably leads to broad spectral lines, limiting the […]

Felipe Pedreros Bustos awarded the Marie Curie Fellowship

 Felipe, the first PhD graduate from our group in Mainz, has received the prestigious Marie Sklodowska-Curie Fellowship for a period of two years to develop research at the Laboratoire d’Astrophysique de Marseille in France. Felipe will build a prototype of a laser-guidestar wavefront sensor, for telescopes like the ESO’s Extremely Large Telescope (ELT). This prototype will allow to test new technologies […]

A step to accelerated preclinical studies using fumarate as a biomarker

We demonstrate a cheap and scalable way to form the biomolecule fumarate (a type of chemical compound) from an enriched form of hydrogen gas, which opens a door to studying metabolism and cell death in vivo via magnetic resonance imaging. The research has been featured in a JACS Spotlight: Hyperpolarized Hydrogen Empowers a New Biomarker Article URL: https://pubs.acs.org/doi/10.1021/jacs.9b10094 […]
