Recycling Mimeograph-Printed Newsprint Paper

open access: yesASEAN Journal on Science and Technology for Development, 2011
Virgin newsprint paper from thermo-mechanical pulp was subjected to a laboratory recycling scheme, which involved mimeograph-printing, re-pulping, de-inking, washing, refining, and handsheetforming, without adding other fibre in between cycles.

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

open access: yesJournal 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.

Cis‐Vaccenic Acid as a Compositional Marker for Detecting High‐Oleic Seed Oil Adulteration in Avocado Oil

open access: yesJournal of the American Oil Chemists' Society, EarlyView.
ABSTRACT The rapid expansion of the global avocado oil market has intensified concerns about economic adulteration with lower‐cost, high‐oleic seed oils that resemble the fatty acid specifications of avocado oil. Cis‐vaccenic acid C18:1 (n−7) occurs at higher proportions in avocado oil than in common seed oil adulterants, making it a promising ...

Histology and fossil diagenesis of a pterosaur tooth from the Crato Formation (Lower Cretaceous of Brazil)

open access: yesThe Anatomical Record, EarlyView.
Abstract Pterosaur dental biology remains poorly understood despite its importance for comprehending feeding strategies and flight adaptations. Here, we present the first comprehensive histological analysis of an ornithocheiriform pterosaur tooth from the Lower Cretaceous Crato Formation (Santana Group, Northeast Brazil).
