Tracking Microhydration of the NaCl Rocksalt Molecule by Quantum Chemical Calculations and Penning Ionization Electron Spectroscopy in Helium Nanodroplets

Small Structures, Volume 7, Issue 5, May 2026.
This study combines quantum chemical calculations and high‐resolution Penning ionization electron spectroscopy in helium nanodroplets to investigate NaCl microhydration. It reveals the transition from contact to solvent‐separated ion pairs and quantifies hydration shell completion at about 34 water molecules.

Impact of Microdosimetric Modeling on Computation of Relative Biological Effectiveness for Carbon Ion Radiotherapy

Radiation
Microdosimetry plays a critical role in particle therapy by quantifying energy deposition within microscopic domains to assess biological effects. This study evaluates the influence of different microdosimetric functions (MFs) and domain geometries (DGs)

Variable relative biological effectiveness (RBE) in proton therapy of gliomas

, 2021
Derzeit gibt es eine intensive Debatte über die Notwendigkeit, Variationen der relativen biologischen Wirksamkeit (RBE) in der Protonentherapie zu berücksichtigen. Hier wurde die Variabilität der RBE für späte strahleninduzierte Hirnverletzungen (RIBI) untersucht, die nach einer Protonentherapie von Gliom-Hirntumorpatienten diagnostiziert wurden.

Cellular repair/misrepair track model [PDF]

A repair/misrepair cell kinetics model is superimposed onto the track structure model of Katz to provide for a repair mechanism. The model is tested on the repair-dependent data of Yang et al. and provides an adequate description of that data.

Detailed analysis of the cell-inactivation mechanism by accelerated protons and light ions

, 2005
Published survival data for V79 cells irradiated by monoenergetic protons, helium-3, carbon, and oxygen ions and for CHO cells irradiated by carbon ions have been analyzed using the probabilistic two-stage model of cell inactivation.
