Modeling the behavior of hot oxygen ions [PDF]

open access: yesAnnales 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

Sputtering of Oxides from LaNi5 Surface

open access: yesEast European Journal of Physics, 2021
The changes in chemical composition of the intermetallic alloy LaNi5 surface monolayers were studied using secondary ion mass spectrometry (SIMS) in the process of the alloy interaction with oxygen.

Structure of adsorbed organometallic rhodium: model single atom catalysts [PDF]

open access: yes, 2007
We have determined the structure of a complex rhodium carbonyl chloride [Rh(CO)(2)Cl] molecule adsorbed on the TiO2 (110) surface by the normal incidence x-ray standing wave technique.

Characterization of the mixed radiation field produced by carbon and oxygen ion beams of therapeutic energy: A Monte Carlo simulation study

open access: yesJournal of Medical Physics, 2019
Purpose: The main advantages of charged particle radiotherapy compared to conventional X-ray external beam radiotherapy are a better tumor conformality coupled with the capability of treating deep-seated radio-resistant tumors. This work investigates the

Regulation of oxygen sensing by ion channels [PDF]

open access: yesJournal of Applied Physiology, 2004
O2sensing is of critical importance for cell survival and adaptation of living organisms to changing environments or physiological conditions. O2-sensitive ion channels are major effectors of the cellular responses to hypoxia. These channels are preferentially found in excitable neurosecretory cells (glomus cells of the carotid body, cells in the ...

Dispersive Alfvén Wave Control of O+ Ion Outflow and Energy Densities in the Inner Magnetosphere

open access: yesGeophysical Research Letters, 2019
The relationship between dispersive Alfvén waves (DAWs), magnetospheric activity, and O+ ion outflow/energy density is examined using measurements from the Van Allen Probes.

Ultrahigh Oxygen Ion Mobility in Ferroelectric Hafnia

open access: yesPhysical Review Letters, 2023
Ferroelectrics and ionic conductors are important functional materials, each supporting a plethora of applications in information and energy technology. The underlying physics governing their functional properties is ionic motion, and yet studies of ferroelectrics and ionic conductors are often considered separate fields.

Ion escape from the high latitude magnetopause: analysis of oxygen and proton dynamics in the presence of magnetic turbulence [PDF]

open access: yesAnnales Geophysicae, 2007
Recent Cluster observations of the vicinity of the high latitude magnetopause indicate the presence of beams of singly charged oxygen ions, which are of ionospheric origin.

Electronic band gap reduction and intense luminescence in Co and Mn ion-implanted SiO$_2$ [PDF]

open access: yes, 2014
Cobalt and manganese ions are implanted into SiO$_2$ over a wide range of concentrations. For low concentrations, the Co atoms occupy interstitial locations, coordinated with oxygen, while metallic Co clusters form at higher implantation concentrations ...
