Evaluating Biomass‐Derived Electrospun Electrodes Using Nonaqueous Redox Flow Cells
Batteries &Supercaps, Volume 9, Issue 6, June 2026.Electrospun electrodes, derived from lignin and polyacrylonitrile feedstocks, were synthesized and compared to a commercial binder‐free carbon paper. The electrochemical and fluid dynamic performance of all three electrodes was investigated in a diagnostic flow cell with a nonaqueous electrolyte. While the commercial electrode outperformed the in‐house

Rapid Detection of Plasticizer Migration From UV‐Aged PVC Films by DART‐HRMS
Rapid Communications in Mass Spectrometry, Volume 40, Issue 10, 30 May 2026.ABSTRACT Rationale The migration of phthalate plasticizers from high‐volume polymers, such as poly(vinyl chloride) (PVC), raises significant toxicological concerns, particularly when materials are subjected to aging and environmental stress. As traditional monitoring techniques rely on time‐consuming solvent extraction and chromatographic methods that ...

ChemBioChem, Volume 27, Issue 10, 27 May 2026.Biomimetic membranes (liposomes) were prepared from yeast phospholipids with variable concentrations of ergosterol and exposed to antimicrobial compounds. Dynamic and electrophoretic light scattering measured changes in size and ζ‐potential to study their interaction with the antimicrobial compounds.

Aqueous Dissolution and Recovery of Poly(Vinyl Alcohol) in Multilayer Film
ChemSusChem, Volume 19, Issue 10, 27 May 2026.Schematic of a water‐based recycling process for PVOH/PBAT‐PLA tri‐layer films, showing selective PVOH dissolution, process condition screening, and recovery of both polymer fractions. In this work, solvent‐based recycling was applied to a multilayer film of PBAT‐PLA and PVOH, where the dissolution conditions were optimized and the reusability of the ...

Achieving Near‐Complete Dechlorination of Poly(vinyl chloride) via Electrochemical Reduction
ChemSusChem, Volume 19, Issue 10, 27 May 2026.A one‐pot controlled‐voltage electrolysis achieved up to 97% dechlorination of poly(vinyl chloride) using common plasticizers as redox mediators. The liberated chloride ions were oxidized at the anode and utilized in a subsequent arene chlorination, offering a route for repurposing the chlorine from PVC.

Stoichiometry of hemolysis by the polyene antibiotic lucensomycin.
, 1976 The stoichiometry of hemolysis by the polyene antibiotic lucensomycin was investigated. It appears that hemolysis occurs only when a relatively high fraction (probably between 15 and 40%) of the cholesterol sites in the erythrocyte membrane have combined
