Astrophysical ices are exposed to different radiation fields including photons, electrons and
ions. The latter stem from interstellar cosmic rays (CR), the solar and stellar winds, shock …

The effective use of swift ion beams in cancer treatment (known as hadrontherapy) as well
as appropriate protection in manned space missions rely on the accurate understanding of …

Radiolysis of biomolecules by fast ions has interest in medical applications and
astrobiology. The radiolysis of solid D-valine (0.2–2 μm thick) was performed at room …

We publish three Roadmaps on photonic, electronic and atomic collision physics in order to
celebrate the 60th anniversary of the ICPEAC conference. Roadmap III focusses on heavy …

Nucleobases are of significant importance to all known organisms, may be an important
building block of life, and could be important biosignatures of current or past life. Given their …

Ices are omnipresent in cold regions in space on, eg, comets, dust grains, transneptunian
objects, surfaces of planets and their satellites. The dominant molecule in such ices is water …

The RNA nucleosides, namely adenosine, cytidine, guanosine and uridine were γ-radioyzed
in solid state and in vacuo at room temperature to a total dose of 3.2 MGy. Through …

Abstract Thymine (C 5 H 6 N 2 O 2) is a basic N-heterocyclic nucleobase in all known
organisms, and this molecule is also found in meteoritic materials. This study aims to …

Cancer is still the leading cause of death in both developing and economically developed
countries. There is still a need to create new drugs with higher efficacy despite substantial …

Knowledge on amino acid's dissociation rates by solar wind is relevant for the study of
biomaterial resistance in space. The radiolysis and sputtering of glycine by 1 keV electron …
