Advances in Structural Separation Technologies for Multilayer Packaging Recycling

Advanced Sustainable Systems, Volume 10, Issue 6, June 2026.
This review structures the field of multilayer packaging recycling by organizing structural separation technologies by their primary working principles. It compares delamination and selective dissolution‐precipitation across material classes, solvent systems, recovery quality, and industrial readiness.

Gas‐Phase Hydrodeoxygenation of m‐Cresol Using Isopropanol as Hydrogen Donor Over a Ni‐Supported Catalyst

ChemCatChem, Volume 18, Issue 11, 15 June 2026.
Continuous‐flow hydrodeoxygenation of m‐cresol assisted by catalytic transfer hydrogenation (CTH‐HDO) was carried out at 300°C and atmospheric pressure over a Ni/SBA‐15 catalyst, using isopropanol as a renewable hydrogen donor. Under optimized conditions, a toluene selectivity of 56% was achieved, highlighting the potential of this approach as a safer ...

Stereoselective Production of Fluorohydrins Biocatalyzed by an Alcohol Dehydrogenase From Pichia glucozyma

ChemCatChem, Volume 18, Issue 11, 15 June 2026.
Ketoreductase from Pichia glucozyma (KRED1‐Pglu) has been successfully employed for the stereoselective bioreduction of α‐halogenated ketones using the purified protein, or alternatively a lyophilized whole cell preparation overexpressed in E. coli. Better chemoselectivities were found with pure biocatalyst, obtaining a series of chiral fluorohydrins ...

Benchtop NMR Spectroscopy of Pyrolysis Oils From Mixed Plastic Waste: Parameter Optimization for Oil Characterization and Detection of Heteroatom‐Containing Compounds

Chemistry–Methods, Volume 6, Issue 6, June 2026.
In this article, benchtop‐NMR spectroscopy was evaluated as an analytical method for the characterization of plastic waste derived pyrolysis oils. The signal‐to‐noise ratio was enhanced via measurement parameter optimization and optimization of postacquisition parameters.
