This is a review of work pertaining to noncovalent binding interactions involving primarily the
cationic guanidinium group and the anionic sulf [on] ate and phosph [on] ate groups. 1 To a …

The low density of ions in mass spectrometers generally precludes direct infrared (IR)
absorption measurements. The IR spectrum of an ion can nonetheless be obtained by …

A stable colloid of g-C3N4 nanosheets was prepared on a large scale via a H2SO4
exfoliation route. The amphoteric nature due to the simultaneous presence of carboxyl and …

The last few years have seen a very rapid growth in understanding the influence of non-
bonded, particularly hydrogen-bonded interactions, on the shapes and conformations of …

This article provides a review of recent studies of the properties of unsolvated (and partially
solvated) peptides and proteins. The methods used to produce vapor-phase peptide and …

Utilization of uranium resource in seawater are highly possible to meet the growth demands
for the sustainable development of nuclear energy industry. Bio-adsorbents exhibit high …

The vibrational spectra of the gaseous sodium complexes of glycine (Gly− Na+) and proline
(Pro− Na+) have been recorded in the spectral range 1150− 2000 cm-1. The complexes …

Collision cross sections have been measured for a series of N-and C-methylated glycines
cationized by alkali ions using ion mobility methods. In all cases the measured cross …

A full structural assignment of the most stable conformers of phenylalanine, based upon a
combination of ultraviolet and infrared ion-dip spectroscopy of the jet-cooled amino acid …

While the naturally occurring amino acids are not zwitterions in the vapor phase, they are in
aqueous solutions, implying that water plays an important role in inducing zwitterion …
