Holographic Photopolymerizable Glass: Enhancing Exposure Sensitivity by Tailoring Photoinitiating Systems Based on BODIPY Dyes

Advanced Photonics Research, Volume 7, Issue 3, March 2026.
The holographic recording performance of the photopolymerizable hybrid sol–gel is enhanced by optimizing photoinitiating systems based on boron dipyrromethene dyes. Two‐ and three‐component type‐II photoinitiating systems are employed, and their photopolymerization efficiency is evaluated through holographic patterning at 532 nm.

Photocatalytic CO‐Free Hydroformylation: Unlocking New Horizons for a Classic Reaction

ChemCatChem, Volume 18, Issue 5, 13 March 2026.
ABSTRACT Hydroformylation, the conversion of alkenes into aldehydes, is a cornerstone industrial process, as aldehydes serve as versatile intermediates for numerous chemical transformations. Conventionally, this process operates under pressure of CO and H2 (syngas) and relies on homogeneous catalysis.

Making Blank Faces Expressive: Chemical Approaches to the Modification of Chemically Inert Peptides

Journal of Peptide Science, Volume 32, Issue 3, March 2026.
As an alternative to the conventional approach, which combines amino acid monomers in a one‐by‐one fashion to peptide derivatives, the chemical modification of existing peptides has attracted significant attention in recent years. However, such approaches generally target the reactive functional groups in cysteine and lysine residues, particularly in ...
