DOI: 10.1016/j.ijms.2018.10.038

Abstract: Abstract The Q-value for the neutrinoless double electron capture on 102Pd, Qϵϵ(102Pd), is determined as the atomic mass difference between 102Pd and 102Ru. A precise measurement of the Qϵϵ(102Pd) at the SHIPTRAP Penning trap showed… read more here.

DOI: 10.1021/acs.analchem.5c02420

Abstract: We report an improved, fully automated method of mass spectral calibration that relies on mass differences instead of internal calibrants. First, we introduce the mass difference spectrum and note that confident elemental formulas can be… read more here.

DOI: 10.1103/physrevlett.124.113001

Abstract: First ever measurements of the ratios of free cyclotron frequencies of heavy, highly charged ions with Z>50 with relative uncertainties close to 10^{-11} are presented. Such accurate measurements have become realistic due to the construction… read more here.

DOI: 10.3389/fmolb.2022.917911

Abstract: Untargeted metabolomics seeks to identify and quantify most metabolites in a biological system. In general, metabolomics results are represented by numerical matrices containing data that represent the intensities of the detected variables. These matrices are… read more here.
