Molecularly Regulated Dynamic Interfaces in 3D/2D Perovskites Enabled by Functional Pyridinium Ionic Liquids

open access: yesSmall, EarlyView.
1‐butyl‐4‐methylpyridinium tetrafluoroborate (BMPyBF4) interacts with excess PbI2 during film formation, driving the formation of a low‐dimensional perovskite phase and enabling the self‐organization of a 3D/2D interfacial structure. This molecularly regulated interface suppresses defect‐mediated recombination and facilitates interfacial charge ...

Spectroscopic analysis of bacterial photoreactivation

open access: yesPhotochemistry and Photobiology, Volume 101, Issue 2, Page 494-504, March/April 2025.
This study investigates the effectiveness of fluorescence and Raman spectroscopy in detecting bacterial photoreactivation. Fluorescence spectroscopy shows limitations, because the intense fluorescence of tryptophan and tyrosine masks fluorescence emitted by thymine molecules.

VUV and mid‐UV photoabsorption cross sections of thin films of glycine and alanine: Application to their photochemistry in the solar system

open access: yesPhotochemistry and Photobiology, EarlyView.
Thin solid films of pure glycine or alanine (thicknesses ranging from 10 to 700 nm) were prepared on MgF2 windows using a vacuum sublimation/recondensation method. VUV‐UV spectroscopy of these films enabled us to characterize new absorption cross sections for glycine and alanine for VUV‐UV radiations between 120 and 300 nm.

First 20 Years of Orbitrap Mass Spectrometry as the Mainstream Analytical Technique

open access: yesMass Spectrometry Reviews, Volume 45, Issue 6, Page 1064-1086, November/December 2026.
ABSTRACT This review traces the first 20 years of Orbitrap mass spectrometry as a mainstream high‑resolution and accurate‑mass (HR/AM) technology. It outlines the historical development of the Orbitrap analyzer, the evolution of major instrument families, and the key technological innovations that enabled its widespread adoption. Particular emphasis is

Charge Resonance Interaction in Aromatic Trimer Radical Cations Revealed by IR Spectroscopy: The Case of Pyrrole Homo‐ and Heterotrimers

open access: yesChemistry – A European Journal, Volume 32, Issue 38, 13 October 2026.
We demonstrate the power of high‐resolution infrared spectroscopy and complementary quantum chemical calculations to unravel the evolution of the aromatic charge resonance interaction (CR) in cold trimer radical cations for the prototypical pyrrole clusters.

Metal‐Ion Regulated Light‐Free Z→E Isomerization of Azobenzene Glycomacrocycle

open access: yesChemistry – A European Journal, Volume 32, Issue 38, 13 October 2026.
Metal ion‐catalyzed Z→E isomerization of photoswitchable azobenzene glycomacrocycle: A new azobenzene‐based glycomacrocycle is capable of forming a 1:1 complex with divalent metal ions in both E‐ and Z‐isomers. The complexes undergo light‐free Z→E isomerization in a timescale spanning from seconds to weeks.
