Bifunctional catalytic activity of anion-doped LaSrCoO4 for oxygen reduction and evolution reactions
Royal Society Open ScienceHere, we synthesized Co-based, anion-incorporated Ruddlesden–Popper perovskite electrocatalysts (LaSrCoO4−x X y ) and compared their catalytic performances in the oxygen reduction reaction (ORR) and oxygen evolution reaction (OER).

Recent Advances in Homogeneous Metal-Catalyzed Aerobic C–H Oxidation of Benzylic Compounds [PDF]
, 2018 Csp(3)-H oxidation of benzylic methylene compounds is an established strategy for the synthesis of aromatic ketones, esters, and amides. The need for more sustainable oxidizers has encouraged researchers to explore the use of molecular oxygen.

High Oxygen Treatment Increases Antioxidant Capacity and Postharvest Life of Strawberry Fruit
Food Technology and Biotechnology, 2007 The antioxidant capacity, total phenolics, volatile compounds, and postharvest quality of strawberry fruit were evaluated after storage in high oxygen atmospheres (40, 60, 80, and 100 kPa) during 14 days at 5 °C.

Highly reversible oxygen redox in layered compounds enabled by surface polyanions
Nature Communications, 2020 Oxygen-anion redox in lithium-rich layered oxides can boost the capacity of lithium-ion battery cathodes. Here, the authors investigate the mechanism of surface degradation caused by oxygen oxidation and the kinetics of surface reconstruction.

A simple and efficient method for the preparation of 5-hydroxy-3-acyltetramic acids
Beilstein Journal of Organic Chemistry, 2015 Oxidation of the bisenolates of 3-acyltetramic acid to the corresponding 5-hydroxylated compounds using molecular oxygen is reported. The deprotection of the resulting compounds was also achieved.
