Exploring a Ugi‐Mediated Polymerization‐Induced Self‐Assembly Approach to Peptoid Particles

open access: yesMacromolecular Rapid Communications, EarlyView.
Ugi‐mediated polymerization‐induced self‐assembly (U‐PISA) enables the one‐pot synthesis of PEG‐stabilized polypeptoid nanoparticles under mild aqueous conditions. By tuning PEG molar mass and feed composition, tunable spherical and worm‐like nano‐objects are obtained.

Tracking Photocatalytic Pathways With In Situ Surface‐Enhanced Raman Spectroscopy

open access: yesTransformative Chemistry, EarlyView.
In situ SERS captures surface molecular fingerprints during photocatalysis, revealing transient intermediates, bond evolution, pathway selectivity, and charge‐coupled molecular transformation beyond catalyst‐ or product‐centered characterization. This review maps SERS‐active platforms and future site‐specific, time‐resolved, intelligent strategies for ...

The Importance of Thermodynamic Data for Pyrrole Pyrolysis and Combustion Chemistry

open access: yesChemPhysChem, Volume 27, Issue 18, 28 September 2026.
High level ab initio quantum chemical computations with ORCA 6.1.1 are done to derive enthalpy and entropy of formation at 298.15 K for 32 species that include both radicals and stable molecules relevant to the pyrolysis and combustion of pyrrole. The effects of thermochemical data on chemical model performance are assessed.
