Impact of glacial cycles and ocean currents on radiation events in the Japanese turban snail Lunella coreensis

open access: yesLimnology and Oceanography Letters, EarlyView.
Abstract The Japanese turban snail Lunella coreensis is sensitive to ocean currents due to its short pelagic larval stage and moderate dispersal ability, making it an ideal model for studying genetic diversity shaped by paleoclimatic shifts. In this study, we analyzed the mitochondrial genes COI and 12S of museum samples collected from various coasts ...

Ion Chemistry in Dielectric Barrier Discharge Ionization: Recent Advances in Direct Gas Phase Analyses

open access: yesMass Spectrometry Reviews, EarlyView.
ABSTRACT Dielectric barrier discharge ionization (DBDI) sources, employing low‐temperature plasma, have emerged as sensitive and efficient ionization tools with various atmospheric pressure ionization processes. In this review, we summarize a historical overview of the development of DBDI, highlighting key principles of gas‐phase ion chemistry and the ...

Reactivity of Imidazole‐ and Pyridine‐Carboxaldehydes for Gem‐Diol and Hemiacetal Generation: Theoretical and Experimental Insights

open access: yesChemistryOpen, EarlyView.
The generation of the gem‐diol and hemiacetal forms using pyridine‐ and imidazole‐carboxaldehyde isomers in different chemical environments was studied by NMR spectra and combined with theoretical calculations. Unlike aprotic solvents, protic ones, as water and methanol, favored the generation of the gem‐diol and hemiacetal structures.
