Hypothesis : soluble Aβ oligomers in association with redox-active metal ions are the optimal generators of reactive oxygen species in Alzheimer's disease [PDF]

open access: yes, 2010
Considerable evidence points to oxidative stress in the brain as an important event in the early stages of Alzheimer's disease (AD). The transition metal ions of Cu, Fe, and Zn are all enriched in the amyloid cores of senile plaques in AD.

Oxygen-Storage Materials to Stabilize the Oxygen Redox Activity of Three-Layered Sodium Transition Metal Oxides

open access: yes, 2021
To double the energy density of lithium- and sodium-ion batteries there is a need to activate simultaneously cationic and anionic redox reactions at the intercalation-type electrodes.

Dynamic plastid redox signals integrate gene expression and metabolism to induce distinct metabolic states in photosynthetic acclimation in Arabidopsis [PDF]

open access: yes, 2009
Plants possess acclimation responses in which structural reconfigurations adapt the photosynthetic apparatus to fluctuating illumination. Long-term acclimation involves changes in plastid and nuclear gene expression and is controlled by redox signals ...

Oxygen Redox Activity in Cathodes: A Common Phenomenon Calling for Density-Based Descriptors

open access: yes, 2020
Lithium-excess transition metal oxide materials are promising cathode candidates for future secondary batteries due to their relatively high energy density, which is commonly related to redox-active oxygen centers.

Oxygen-redox activity in non-Li-excess W-doped LiNiO2 cathode

open access: yes, 2023
The desire to increase the energy density of stoichiometric layered LiTMO2 (TM = 3d transition metal) cathode materials has promoted investigation into their properties at high states of charge. Although there is increasing evidence for pronounced oxygen

Correlation between oxygen redox and structure of oxide cathode materials

open access: yesNext Materials
Redox of the transition metals is definitely the most important way of charge compensation in the conventional electrode materials. Utilization of oxygen redox (or more popularly the anionic redox) is another effective strategy to capture extra ...

Spatial oxygen heterogeneity in a Hediste diversicolor irrigated burrow [PDF]

open access: yes, 2011
The heterogeneity of oxygen distribution in a Hediste diversicolor burrow environment was investigated in a laboratory experiment using a 6-mm thick tank equipped with oxygen planar optodes. The twodimensional oxygen distribution in a complete burrow was
