Ion Transfer During Ionomer Contact Electrification: Binding Affinity Controls Charging

open access: yesAngewandte Chemie International Edition, EarlyView.
The binding affinity between mobile ions and fixed ionomer groups determines the amount of charge transferred during contact electrification. Ionomers with a series of mobile alkali cations as well as mobile anions establish a clear ordering in charge transfer, where higher interaction strength leads to lower charge transfer.

Optimization of Saponification Process for Quantification of Individual and Total Tocopherols and Phytosterols in Canola Oil Refining By‐Products

open access: yesJournal of the American Oil Chemists' Society, EarlyView.
ABSTRACT In this study, saponification variables were optimized using a face‐centred central composite design‐response surface methodology. The variables included reaction temperature (50°C–120°C), reaction time (30–180 min), KOH concentration (0.5–3 M) and pyrogallol concentration (0–1% w/v).
