Improved Antioxidant Properties of Pistacia lentiscus L. Oleo‐gum Resin Essential Oil Extracted by Superheated Steam: Process Optimization and Chemical Characterization

Food Science &Nutrition, Volume 14, Issue 10, October 2026.
Pistacia lentiscus L. oleo‐gum resin was subjected to different extraction techniques, including hydro‐distillation, superheated steam extraction, and steam distillation, for the extraction of EO. The extracted EOs were characterized by GC–MS analysis and further evaluated for their antioxidant and antimicrobial activities.

In‐Situ Construction of Multi‐Scale Heterogeneous Structures in L‐DED IN718 Coatings via WMoTaNb Incorporation for Enhanced Strength‐Toughness Synergy

Rare Metals, Volume 45, Issue 10, October 2026.
ABSTRACT To improve the strength–toughness balance of IN718, and alleviate the brittleness commonly associated with refractory high‐entropy alloys, this study proposes a novel strategy to fabricate defect‐free IN718/WMoTaNb heterogeneous multiprincipal element alloy coatings via laser‐directed energy deposition.
