Exploring the Fragmentation of Sodiated Species Involving Covalent‐Bond Cleavages for Metabolite Characterization

open access: yesRapid Communications in Mass Spectrometry, EarlyView.
ABSTRACT Rationale Electrospray (ESI), the most popular desorption/ionization technique used in mass spectrometry‐based metabolomics, generates both protonated and deprotonated molecules, as well as adduct ions, sodium being the most frequent monoatomic cation entering their composition.

Growth Techniques for Bulk ZnO and Related Compounds

open access: yes, 2011
ZnO bulk crystals can be grown by several methods. 1) From the gas phase, usually by chemical vapor transport. Such CVT crystals may have high chemical purity, as the growth is performed without contact to foreign material.

On the Nature of Improper Hydrogen Bonding in RCH2F and RCHF2 Motifs

open access: yesAngewandte Chemie, Volume 138, Issue 2, 9 January 2026.
The nature of ‘improper’ hydrogen bonds is explored in FnC─H⋯X systems, such as RCF2H interaction with chloride and water. It is noted that increased fluorination decreases the positive charge density on H but increases it on C, thus these interactions are dominated by electrostatic attraction to C over H.

Frame‐Shifted Synthesis of Oligoheterocycles as a Platform for Molecular Design

open access: yesAngewandte Chemie, Volume 138, Issue 2, 9 January 2026.
Modern chemistry seeks to turn the simple raw materials into complex molecules that matter in health, agriculture, and technology. Among these, oligoheterocycles stand out for their versatility, yet they are most often built by cross‐coupling reactions that often rely on expensive metal catalysts.
