Amphiphilic Cu(II) Oxacyclen Complexes: From Oxidative Cleavage to Condensation of DNA

ChemBioChem, Volume 27, Issue 2, January 2026.
Monoalkylated Cu(II) oxacyclen complexes show a dual DNA effect: shorter alkyl chains enable ROS‐mediated DNA cleavage, whereas longer chains cause strong DNA condensation/aggregation. Thus, chain length controls activity. Using circular dichroism, UV/visible and fluorescence spectroscopy, atomic force microscopy, dynamic light scattering, and ...

CO2 Sorption on PEI‐Impregnated Mesoporous Silica for Direct Air Capture and Subsequent Conversion to Methanol

ChemCatChem, Volume 18, Issue 1, 15 January 2026.
ABSTRACT Amine‐impregnated mesoporous materials are studied for CO2 sorption at conditions of direct air capture (DAC). Mesoporous silica supports with identical specific pore volume of 0.8 cm3 g−1 but varying pore width (7 – 50 nm) were impregnated with polyethyleneimine (PEI) of different molecular mass (600 – 2000 g mol−1) and loading (20 – 43 wt.‐%)

Modeling and Simulation of Combined CO2 Capture and Hydrogenation to Methanol at Atmospheric Pressure and Low Temperature

ChemCatChem, Volume 18, Issue 2, 28 January 2026.
This study investigates and models a bifunctional catalyst system for CO2 capture and hydrogenation to methanol at low temperatures. Using kinetic data from TGA and steady‐state reactions, a transient reactor model predicts methanol formation. Parametric analysis highlights optimal isothermal cycles and material improvements for enhanced efficiency ...
