Sustainable Palm Oil Extraction and Trends in the Use of Green Technologies: State‐of‐the‐Art and Future Directions

Journal of the American Oil Chemists' Society, EarlyView.
ABSTRACT Palm oil, which is extracted from the mesocarp of the fruit of the Elaeis guineensis Jacq. palm tree, is the most widely produced vegetable oil in the world. The extraction of this substance typically utilizes the conventional pressing method, a technique that is advantageous due to its low operating cost and simplified process.

Linear Viscoelastic Behavior of n‐Alkane Diluted Polyethylene Melts: Sorption, Desorption, and Oscillatory Rheometry

Journal of Applied Polymer Science, EarlyView.
This study systematically maps polyolefin dilution dynamics using a homologous series of n‐alkanes. Integrating gravimetric sorption, subsequent controlled desorption, and oscillatory rheometry establishes a precise framework to analyze reduction in viscosity at least for polymer diluent mixtures with polymer concentration > 35% and diluent ...
