Influence of Direct Saponification Conditions on Sterol Yield and Composition of the Unsaponifiable Fraction of the Microalga Isochrysis galbana and the Seaweed Ascophyllum nodosum

Journal of the American Oil Chemists' Society, EarlyView.
ABSTRACT Saponification is a key step for recovering the unsaponifiable fraction (USF) of lipids, which contains bioactive sterols, tocopherols, and carotenoids. This study optimized direct saponification conditions (50–300 g L−1 KOH; 60°C–100°C) to recover sterol‐rich USFs from the microalga Isochrysis galbana and the brown seaweed Ascophyllum nodosum,

A Simple Solvent Treatment to Modulate the Thermoelectric Properties of Single‐Walled Carbon Nanotubes over a Wide Range

Advanced Physics Research, EarlyView.
This study explores the use of single‐walled carbon nanotubes (SWCNTs) for thermoelectric (TE) applications to convert waste heat into electricity. By examining two SWCNT types with varying purity, structure, and thickness, it assesses how different solvents used in buckypaper fabrication affect their TE properties.
