Superior tumor cell killing by oxygen ion beam irradiation compared to carbon ions and photons in pancreatic Cancer cells – An in vitro investigation [PDF]

Clinical and Translational Radiation Oncology
Pancreatic cancer remains one of the most treatment-refractory malignancies, displaying profound resistance to chemotherapy and radiotherapy. While the benefit of photon radiotherapy remains debated, heavy-ion modalities such as carbon ions show promise ...

Oxygen in the Earth System

Oxygen, 2023
Atmospheric oxygen is produced and consumed by life on Earth, and the ozone layer protects life on Earth from harmful solar UV radiation. The research on oxygen in the Earth system is of interest to many different geoscientific communities, from ...

Van Allen Probes Observations of Oxygen Ions at the Geospace Plume

Frontiers in Astronomy and Space Sciences, 2021
The geospace plume couples the ionosphere, plasmasphere, and magnetosphere from sub-auroral regions to the magnetopause, on polar field lines, and into the magnetotail.

Influence of Oxygen Ion Migration from Substrates on Photochemical Degradation of CH₃NH₃PbI₃ Hybrid Perovskite

Energies, 2021
Measurements of XPS survey, core levels (N 1s, O 1s, Pb 4f, I 3d), and valence band (VB) spectra of CH3NH3PbI3 (MAPbI3) hybrid perovskite prepared on different substrates (glass, indium tin oxide (ITO), and TiO2) aged under different light-soaking ...

Radioactive Beams for Image-Guided Particle Therapy: The BARB Experiment at GSI

Frontiers in Oncology, 2021
Several techniques are under development for image-guidance in particle therapy. Positron (β+) emission tomography (PET) is in use since many years, because accelerated ions generate positron-emitting isotopes by nuclear fragmentation in the human body ...

Large-scale inverted-V channels of upflowing oxygen ions pumped by Alfvén waves

Earth and Planetary Physics, 2023
Large-scale inverted-V channels of upflowing oxygen ions are frequently identified in data collected by Cluster, at all local times, near the open-closed field line boundary over Earth’s high-latitude ionosphere-occur with downward propagating MHD Alfvén

Radioactive Beams in Particle Therapy: Past, Present, and Future

Frontiers in Physics, 2020
Heavy ion therapy can deliver high doses with high precision. However, image guidance is needed to reduce range uncertainty. Radioactive ions are potentially ideal projectiles for radiotherapy because their decay can be used to visualize the beam ...

Distribution of O+ and \begin{document}${\text{O}}_{\text{2}}^{\text{+}}$\end{document} fluxes and their escape rates in the near-Mars magnetotail: A survey of MAVEN observations

Earth and Planetary Physics, 2022
Tailward ion outflows in the Martian-induced magnetotail are known to be one of the major channels for Martian atmospheric escape. On the basis of nearly 6.5 years of observations from the Mars Atmosphere and Volatile EvolutioN (MAVEN) mission, we ...
