First-principles study of low-index surfaces of the Al5Co2complex metallic alloy

“…Among them, atomic densities, interlayer spacing (or gaps between planes in the case of quasicrystals) and chemical composition are key parameters [20]. To study the relative influence of these factors, we have chosen to study two different low-index surfaces of the Al 5 Co 2 alloy, which is an approximant of the decagonal phase [26]. The crystal structure of Al 5 Co 2 belongs to the space group P 6 3 /mmc (hP 28) [27,28].…”

Optimized Fragmentation for Quantitative Analysis of Fucosylated N-Glycoproteins by LC-MS-MRM

“…In the recent years, this technique has been successfuly employed for the quantification of glycopeptides. 5,[12][13][14] Mass spectrometric quantification of glycopeptides is challenging because of the substoichiometric representation of the microheterogeneous glycopeptides and their somewhat lower ionization efficiency; the reported workflows typically measure the low mass oxonium ions, such as m/z 204.1 (HexNAc), 366.1 (HexHexNAc), 138.1 (HexNAc-2H 2 O-CH 2 O), and 274.1 (Neu5Ac-H 2 O). 15,16 The oxonium ions are the major fragment for all N-glycopeptides under CID condition typical for peptide analysis; these ions have high sensitivity but low specificity and cannot distinguish between structural isomers.…”
