Applications of ultra-high resolution microcalorimeter gamma-ray spectrometry Open
Ultra-high energy resolution microcalorimeter gamma-ray spectroscopy—with energy resolution 5 to 10 times better than observed in spectra obtained by commercial-off-the-shelf high purity germanium detectors—is an enabling technology for ul…

Online monitoring of lanthanide species with combined spectroscopy in flowing aqueous aerosol systems Open
Combined spectroscopic analysis through absorption and laser-induced breakdown spectroscopy (LIBS) was used to monitor Nd and Pr concentrations in a flowing aqueous system. An inline sampling approach was employed that allowed for an appro…
