Physiological and Agronomic Responses of Adult Citrus Trees to Oxyfertigation Under Semi-Arid Drip-Irrigated Conditions

Agriculture
Oxyfertigation with hydrogen peroxide (H2O2) has been successfully applied in several crops and production systems, but its use in mature citrus orchards under no-tillage conditions and semi-arid Mediterranean environments remains scarcely studied.

Nanocubes and Cuboctahedra: Entropic Stabilization Versus Thermal Segregation in Rock Salt‐ and Spinel‐Type Multinary Oxides from Spray‐Flame Synthesis

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Spray‐flame synthesis enables highly flexible and scalable production of multinary and high‐entropy oxide nanoparticles due to high synthesis temperatures with subsequent quenching. Temperature‐dependent in situ diffraction of as‐synthesized materials clearly reveals entropy stabilization in rock salt lattices, while spinels—featuring tetrahedral and ...

Facilitating Hydrogen Evolution Reaction Activity in Alkaline Water Electrolysis via Formation of Ni‐Co2P Heterojunction

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Ni‐Co2P synthesized via a co‐sputtering method exhibits enhanced hydrogen evolution reaction (HER) activity. The formation of a heterojunction between Ni and Co2P plays a crucial role in this enhancement. At the Ni‐Co2P junction, water dissociation is significantly promoted, while the Ni sites facilitate efficient hydrogen evolution.
