Chemical Ionization Mass Spectrometry: Fundamental Principles, Diverse Applications, and the Latest Technological Frontiers

open access: yesMass Spectrometry Reviews, EarlyView.
ABSTRACT The review examines the evolution of chemical ionization mass spectrometry (CI‐MS), a technique developed in 1966 by Field and Munson. CI is a soft‐ionization method that produces more intense molecular ions with less fragmentation than electron ionization (EI).

Volatile Organic Compound Fragmentation in the Afterglow of Pulsed Glow Discharge in Ambient Air

open access: yesMolecules, 2022
Glow discharge (GD) source gained an increased level of attention in relation to the analysis of volatile organic compounds (VOCs) since past work showed that this soft ionization method allowed direct analysis of VOCs with minimal fragmentation, however,

Sputter deposition of porous thin films from metal/NaCl powder targets [PDF]

open access: yes, 2019
A method to deposit porous thin films is elucidated. For this purpose, NaCl powder was mixed with a metal powder, cold pressed, and used as a target material in order to deposit a metal/NaCl thin film by DC magnetron sputtering.

Spinel Aluminate‐Based Heterojunctions as Photocatalyst: A Review

open access: yesChemistryOpen, EarlyView.
Spinel aluminates (MAl2O4; M = Zn, Mg, Ca, Sr) serve as robust platforms for designing heterojunction photocatalysts. Their stable lattices, tunable band structures, and efficient charge transport enable improved light‐driven carrier separation, significantly enhancing pollutant degradation efficiency in advanced photocatalytic systems.

Structure‐Function Integration in 2D Hybrid Perovskite for Fast Neutron and Gamma Ray Discrimination

open access: yesAdvanced Science, Volume 13, Issue 13, 3 March 2026.
Using an in situ seed‐assisted cooling method, large (28 × 7 × 3 mm3) (GABA)2PbBr4 single crystals are grown, featuring hydrogen‐rich organic layers and a dense PbBr4 framework. This architecture enables efficient γ‐ray absorption, fast‐neutron sensitivity, and clear n/γ pulse‐shape discrimination (FOM up to 1.74), highlighting its potential as a ...

Tunable fragmentation of organic molecules in laser ablation glow discharge time-of-flight mass spectrometry [PDF]

open access: yes, 2018
A DC-pulsed glow discharge (GD) has distinct temporal regimes which are characterized by "softer” or "harder” ionization of analytes introduced into the discharge.
