Exploiting the unique interaction characteristics of fast neutrons for improved cancer therapy: A radiobiological perspective

Radiation Medicine and Protection
Fast neutrons have sufficient energy to liberate recoil protons, alpha particles, and other products when they interact with the nuclei of the target material through scattering and absorption processes.

Electrical characteristics and deep-level transient spectroscopy of a fast-neutron-irradiated 4H–SiC Schottky barrier diode

Nuclear Engineering and Technology, 2023
The dependence of the electrical characteristics on the fast neutron fluence of an epitaxial 4H–SiC Schottky barrier diode (SBD) was investigated. The 30 MeV cyclotron was used for fast neutron irradiation.

Evaluation of the Potential of Laser Shock Peening Compared with Cold Expansion for Improving Fatigue Resistance of Riveted Lap Joints of Aerospace Grade 7175 Al Alloy

Advanced Engineering Materials, EarlyView.
This study investigates laser shock peening for enhancing fatigue performance of riveted aerospace aluminum joints. A comparative approach with cold expansion combines fatigue testing and synchrotron X‐ray methods. Integrating mechanical testing with residual stress and strain characterization provides insights into how different treatments affect the ...

Understanding and Optimizing Li Substitution in P2‐Type Sodium Layered Oxides for Sodium‐Ion Batteries

Advanced Functional Materials, EarlyView.
This work explores Li‐substituted P2 layered oxides for Na‐ion batteries by crystallographic and electrochemical studies. The effect of lithium on superstructure orderings, on phase transitions during synthesis and electrochemical cycling and on the interplay of O‐ versus TM‐redox is revealed via various advanced techniques, including semi‐simultaneous

Paving the Road for Modern Particle Therapy – What can we Learn from the experience gained with Fast Neutron Therapy in Munich?

Frontiers in Oncology, 2015
While neutron therapy was a highly topical subject in the 70’s and 80’s, today there are only a few remaining facilities offering fast neutron therapy. Nevertheless, up to today more than 30,000 patients were treated with neutron therapy.
