Sustainable Valorization of Olive Oil By‐Products: Green Extraction of Phytochemicals, Encapsulation Strategies, and Food Applications

Journal of Food Science, Volume 90, Issue 7, July 2025.
ABSTRACT Olive oil (OO) production generates significant amounts of by‐products, including olive leaves and pruning residues, olive pomace, OO wastewater, and olive stones. These by‐products are rich in bioactive compounds, particularly polyphenols and secoiridoids, which possess antioxidant, anti‐inflammatory, antimicrobial, and cardioprotective ...

Ti3C2Tx MXene‐Zirconium Diboride Based Ultra‐High Temperature Ceramics

Advanced Science, Volume 12, Issue 23, June 20, 2025.
This study demonstrates the effectiveness of Ti3C2Tx MXenes as additives in ultra‐high‐temperature ceramics (ZrB₂), enhancing densification, reducing oxygen content, and improving mechanical properties. Through surfactant‐free electrostatic self‐assembly and spark plasma sintering, MXenes enabled the formation of a core–shell microstructure, resulting ...

Nozzle Optimization of Dual Thrust Rocket Motors

, 2019
Optimizing the nozzle of a solid propellant rocket motor plays an essential rule in the overall performance of the motor. In this paper, the investigation of an optimization model of dual thrust propellant rocket motors will be presented. Due to having two phases of thrust in this type of rocket motors, determination of the rocket nozzle expansion ...
