Nanostructure-assisted drought tolerance in olive trees ( L.): the role of FeO-graphitic carbon.

Olive trees are known as one of the most iconic crops in the world. Considering the increasing water deficit worldwide, implementing some profitable and empirical strategies can be inevitable upon exposure to drought stress. Therefore, the present study aimed at clarifying the beneficial role of exogenously foliar application of FeO modified carbon nitride nanostructures (control, FeSO, CN and FeO/g-CN) to "Shengeh" olive cultivars grown at different watering levels (100, 75, and 50% ET) in two experimental years (2022 and 2023) and the pomological attributes, physiological and biochemical changes happening in the treated leaves and fruits were discussed.

PdO@CoSe composites: efficient electrocatalysts for water oxidation in alkaline media.

In this study, we have prepared cobalt selenide (CoSe) due to its useful aspects from a catalysis point of view such as abundant active sites from Se edges, and significant stability in alkaline conditions. CoSe, however, has yet to prove its functionality, so we doped palladium oxide (PdO) onto CoSe nanostructures using ultraviolet (UV) light, resulting in an efficient and stable water oxidation composite.
