Excitation spectra up to the ionization threshold are reported for barium atoms located on the surface of helium nanodroplets. For states with low principal quantum number, the resonances are substantially broadened and shifted towards higher energy with r ...
Mass spectrometry-based qualitative and quantitative (bio)molecular analysis is a corner stone in the state-of-the-art pipelines in systems biology and environmental sciences. High-resolution and efficient tandem mass spectrometry methods and techniques ar ...
Proteomics is nowadays one of the most important research topics in life science for understanding many life activities from the molecular level. The objective is to find out proteins or modifications on proteins that regulate biological events, aging, dis ...
The accurate and unambiguous detection of post-translational modifications in proteins and peptides remains a challenging task. We report here the use of cold ion spectroscopy for the identification of phosphorylated tyrosine residues in peptides. This app ...
Results of the mechanistic studies of free-electron based fragmentation methods addressing peptide and protein structure analysis with mass spectrometry (MS), electron capture dissociation (ECD) and electron ionization dissociation (EID), are presented. Se ...
In recent years, spectroscopic investigations of cold, biomolecular ions have started to provide new, detailed information about the structures of biomolecules in the gas phase. The present work comprises three major parts that describe the development of ...
Combined with high and ultra high pressure liquid chromatography, mass spectrometry-based peptide and protein structure analysis requires high resolution and mass accuracy achievable within short ion detection time. Although Fourier transform ion cyclotron ...
The conformations of a number of M2TMP-(22-46) sequence variants have been investigated using ion mobility spectrometry (IMS). Substantial conformational changes were evidenced by IMS upon the variation of a single amino acid in the peptide sequence, with ...
We present in this work experiments that push the limits of cold ion spectroscopy to the study of complex peptides and small proteins in the gas phase. Although the low temperature attainable in a cold ion trap greatly simplifies the electronic spectra of ...
The catalytic hydrogenation of CO 2 at the surface of a metal hydride and the corresponding surface segregation were investigated. The surface processes on Mg 2NiH 4 were analyzed by in situ X-ray photoelectron spectroscopy (XPS) combined with thermal deso ...
