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

, 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.

Microstructural evolution and its influence on oxygen diffusion in yttrium-doped ceria thin films

Materials Research Express, 2022
Ceria doped with rare earth ions (Ce _1−x M _x O _2−y (y = x/2)), which contain many oxygen vacancies, have become excellent electrolyte materials for solid oxide fuel cells and important buffer layers for coated conductors.

Cluster Observations on Time‐of‐Flight Effect of Oxygen Ions in Magnetotail Reconnection Exhaust Region

Geophysical Research Letters, 2020
The D‐shaped ion velocity distribution generated by the time‐of‐flight (ToF) effect can be considered as an important characteristic of reconnection exhausts in the magnetopause and magnetotail reconnection processes.

EISCAT/CRRES observations: Nightside ionospheric ion outflow and oxygen-rich substorm injections [PDF]

, 1996
We present combined observations made near midnight by the EISCAT radar, all-sky cameras and the combined released and radiation efects satellite (CRRES) shortly before and during a substorm.

Discriminative detection of laser-accelerated multi-MeV carbon ions utilizing solid state nuclear track detectors

Scientific Reports, 2021
A new diagnosis method for the discriminative detection of laser-accelerated multi-MeV carbon ions from background oxygen ions utilizing solid-state nuclear track detectors (SSNTDs) is proposed. The idea is to combine two kinds of SSNTDs having different

Oxygen redox chemistry without excess alkali-metal ions in Na2/3[Mg0.28Mn0.72]O2 [PDF]

, 2018
The search for improved energy-storage materials has revealed Li- and Na-rich intercalation compounds as promising high-capacity cathodes. They exhibit capacities in excess of what would be expected from alkali-ion removal/reinsertion and charge ...

Modeling the behavior of hot oxygen ions [PDF]

Annales Geophysicae, 2006
Photochemical processes in the upper atmosphere are known to create significant amounts of energetic oxygen atoms or "hot O". In this research we simulate the effects of ionized hot oxygen, hot O+, on the ionosphere. We find that hot O+ is not able to
