“…The evaporation of ions from the condensed phases to the gas phase is a very important process in many fields such as the thermospray technique for the liquid chromatograph -mass spectrometer interface (23), electrohydrodynamic ionization (electrostatic spray) (24), field ionization, field-induced ion evaporation from liquid surface (25), etc. From the results presented here, one may draw a zeroth order principle that the protic acid ions whose conjugate bases have higher proton affinities are easier to be extracted from the aqueous solution to the gas phase.…”

KENZO HIRAOKA. Can. J. Chem. 65, 1258 (1987. An approximate linear relationship between the proton affinities of conjugate bases (B 's) and the free energies of hydration of conjugate acid ions (BH' 's) is found for B = alkyl-substituted H 2 0 and NH3. With increase in proton affinities, the free energies of hydration increase linearly with a slope of about 1 for analogous compounds. The charge delocalization in the protonated bases and the structure-making effect induced by the hydrophobic groups in the alkyl-substituted H 3 0 + and NH4' are crucial factors in the determination of the free energies of hydration.

This document contains recommendations for terminology in mass spectrometry. Development of standard terms dates back to 1974 when the IUPAC Commission on Analytical Nomenclature issued recommendations on mass spectrometry terms and definitions. In 1978, the IUPAC Commission on Molecular Structure and Spectroscopy updated and extended the recommendations and made further recommendations regarding symbols, acronyms, and abbreviations. The IUPAC Physical Chemistry Division Commission on Molecular Structure and Spectroscopy's Subcommittee on Mass Spectroscopy revised the recommended terms in 1991 and appended terms relating to vacuum technology. Some additional terms related to tandem mass spectrometry were added in 1993 and accelerator mass spectrometry in 1994. Owing to the rapid expansion of the field in the intervening years, particularly in mass spectrometry of biomolecules, a further revision of the recommendations has become necessary. This document contains a comprehensive revision of mass spectrometry terminology that represents the current consensus of the mass spectrometry community.

“…Its large size and low stability are problems (Lemiere 2001). The thermospray (TSP) interface invented in the 1980s allows ionization of nonvolatile analytes with subtle thermal decomposition (Blakey and Vestal 1983, Vestal 1984, Lemiere 2001). An advantage of TSP is its capacity for a large quantity of solvent, which is associated with greater resolution and a fast HPLC flow rate.…”

Emerging studies suggest that seaweeds contain phytohormones; however, their chemical entities, biosynthetic pathways, signal transduction mechanisms, and physiological roles are poorly understood. Until recently, it was difficult to conduct comprehensive analysis of phytohormones in seaweeds because of the interfering effects of cellular constituents on fine quantification. In this review, we discuss the details of the latest method allowing simultaneous profiling of multiple phytohormones in red seaweeds, while avoiding the effects of cellular factors. Recent studies have confirmed the presence of indole-3-acetic acid (IAA), N 6 -(Δ2-isopentenyl)adenine (iP), (+)-abscisic acid (ABA), and salicylic acid, but not of gibberellins and jasmonate, in Pyropia yezoensis and Bangia fuscopurpurea. In addition, an in silico genome-wide homology search indicated that red seaweeds synthesize iP and ABA via pathways similar to those in terrestrial plants, although genes homologous to those involved in IAA biosynthesis in terrestrial plants were not found, suggesting the epiphytic origin of IAA. It is noteworthy that these seaweeds also lack homologues of known factors involved in the perception and signal transduction of IAA, iP, and ABA. Thus, the modes of action of these phytohormones in red seaweeds are unexpectedly dissimilar to those in terrestrial plants.
