Nanomelting and track formation in insulators by swift heavy ions

, 2012
Collisions of swift heavy ions with insulator targets lead to a damage zone around the path of projectiles, so-called tracks. We theoretically investigate the mechanisms leading to track formation and propose a fully microscopic three-step model that ...

The Role of the Crystal Plane Irradiated by Swift Heavy Ions in the Formation of Defects in MgAl₂O₄ Crystals

Crystals
Model experiments were performed on the interaction of swift heavy 220 MeV Xe ions with MgAl2O4 spinel crystal with (100), (110), and (111) planes. A computational analysis of the energy parameters of Xe ions in MgAl2O4 single crystal was performed, and ...

Safeguarding the Photoluminescence of Silver Sulfide Nanocrystals in Biological Environments via Silica Shielding

Small, EarlyView.
Interactions with biomolecules can alter the photoluminescence of Ag2S nanocrystals, undermining near‐infrared imaging and thermometry. Incorporation into dendritic silica minimizes these interactions and preserves emission intensity, spectral response, and lifetime in plasma and whole blood. This shielding enables more reliable imaging and temperature

Theory and simulations for plasma created by swift heavy ions

, 2022
Over one century passes since plasma is thought to be produced in swift heavy ion irradiation, theoretically. However, it is still unclear if this irradiation forms plasma or not.

Nonthermal plasma approaches for combating implant‐associated infections: A compendious review

VIEW, EarlyView.
Implant‐associated infections pose serious clinical challenges. Non‐thermal plasma (NTP) modifications overcome this bottleneck in distinct ways relative to traditional sterilization methods. Gas‐phase plasmas generate highly energetic species, UV radiation and reactive oxygen/nitrogen species (RONS), which alter the implant surface properties.
