Collisional activation spectra and deuterium labelling show that the C2H4O2+· ion formed by McLafferty rearrangement in aliphatic acids does not isomerise to the acetic acid molecular ion.doi:10.1002/chin.197650058Karsten LevsenHelmut Schwarz
Low-energy collision-induced dissociation of B1-type sugar ions formed from peracetylated methyl pentosides and methyl 6-deoxyhexosides Low-energy collision-induced dissociation (CID) was explored for the purpose of differentiating between isomeric pertrideuteroacetylated aldopentosides, 6-...

An electrostatic trap is formed as anions enter the large entrance while they cannot exit the tip (positive external voltages). However, the nanochannel shows high ion currents with no trap when the anode is on the tip side; the negative charge of the inner surface rejects the anion (...
Positive and negative ions formed by attachment processes (p 489-494) Californium-252 plasma desorption mass spectra have been run on a series of typical lipids found in skin, including a fatty acid, a methyl and wax ester, a mono-, di- and triglyceride and an anhydride, in a effort to...
Anisotropic proton-conductive materials formed by the self-organization of phosphonium-type zwitterions. Adv. Mater. 23, 3071–3074 (2011). CAS Google Scholar Soberats, B. et al. 3D anhydrous proton-transporting nanochannels formed by self-assembly of liquid crystals composed of a sulfobetaine ...
The use of a new method for the determination of the absolute electrode potentials and the thermodynamics of individual ions in various solvent systems has been extended to solvents of higher dielectric constant than water, formed by adding structure-breaking urea to water. Standard e.m.f. values...
Very few researches about the corrosion mechanism focused on the naturally formed passive film in the seawater environment, in which condition most marine applications serve. Therefore, it is necessary to investigate the corrosion resistance performance and corrosion mechanism of CP titanium in seawater ...
the locations of the regions of their effective production in the source—positions of the lowest electron temperature and/or of the highest electron density–are nonlocally formed, not only by the plasma expansion through the magnetic filter but also by plasma expansion from the driver into the ...
These results sug- gest that the tetragonal coordination structure of the Cu(II)-DNA complex is formed under the present experimental conditions. The ESR spectrum of a Cu(II)-phos.-PVA complex was very similar to that of the Cu(II)-DNA com- plex. These findings indicate that Cu(II) ...
a three-dimensional network structure is formed. Some researchers have improved the gelation properties of WG by adding potato protein isolate (PPI) (Chen et al., 2019). Potatoes provide a good source of lysine (approximately 7.5%), an amino acid lacking in WG protein (Chen et al., 2019)...
