Post-Irradiation Annealing of Bi Ion Tracks in Si₃N₄: In-Situ and Ex-Situ Transmission Electron Microscopy Study

Crystals
High-energy (710 MeV) Bi ion track morphology in polycrystalline silicon nitride was investigated during post-irradiation annealing. Using both in-situ and ex-situ transmission electron microscopy, we monitored the recovery of crystallinity within ...

Morphology and annealing kinetics of ion tracks in minerals

EPJ Web of Conferences, 2012
We have studied the morphology and annealing kinetics of ion tracks in Durango apatite using synchrotron small angle X-ray scattering. The non-destructive, artefact-free technique enables us to determine the track radii with a resolution of fractions of ...

Coulomb Spike Modelling of Ion Sputtering of Amorphous Water Ice

Quantum Beam Science, 2023
The effects of electronic excitations on the ion sputtering of water ice are not well understood even though there is a clear dependence of the sputtering yield on the electronic stopping power of high-energy ions.

Spectrally resolved ion imaging from laser produced plasmas using CR-39 detectors

AIP Advances, 2021
Intense laser-produced plasmas generate bright, ultrashort bursts of accelerated ions. Reducing the required laser intensity and increasing the repetition rate of the laser to generate high energy ions is important, and mesoscopic particle targets are an

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

FEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...
