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.

Thermal Black‐Infused Polyurethane Rigid Foams: Novel Formulations Toward Higher‐Performance and More Sustainable Insulation

open access: yesJournal of Applied Polymer Science, EarlyView.
Thermal black improves polyurethane foam structure and stability. It helps the foam rise smoothly while promoting the formation of smaller, more uniform cells. The foam keeps its strength and insulation performance while reducing shrinkage. Its clean production and easy processing make it a sustainable, cost‐effective option for high‐performance ...

First‐Principles Investigation of the Structural, Electronic, Optical, Elastic, and Thermal Properties of Defect Diamond‐Like Hg3P2S8

open access: yesAdvanced Physics Research, EarlyView.
The defect diamond‐like material Hg3P2S8 (HPS) is systematically investigated using first‐principles methods to reveal the interplay between highly distorted HgS4 and rigid PS4 units. The HPS material exhibits a strong anisotropic second‐harmonic generation (SHG) response, favorable optical properties, and low thermal conductivity, highlighting its ...

Computational fluid dynamics simulations of airflow through the nasal passages of rhinolophoid bats

open access: yesThe Anatomical Record, EarlyView.
Abstract The nasal passages of bats that emit their echolocation call through their nostrils have adapted for sound emission as well as standard respiratory and olfactory functions. Rhinolophids, hipposiderids and rhinonycterids all use a high duty cycle (HDC) echolocation strategy.

Tracheal chambers as a key innovation for high‐frequency emission in bat echolocation

open access: yesThe Anatomical Record, EarlyView.
Abstract Key innovations are pivotal for biodiversity and facilitating evolutionary success, enabling organisms' adaptation to various ecological niches through the diversification of phenotypic traits. In mammals, notable adaptations include evolving hypsodonty for grazing on grasses and, for bats, evolving echolocation and wing acquisition.
