Ultrathin and thin graphene oxide (GO) membranes with well-defined in-plane nanopores are promising for separation, sensing, molecular transport, and nanofluidic applications. A versatile route to fabricate such porous GO architectures is heavy-ion irradiation in the high electronic energy loss ($S_e$) regime or with intermediate-$S_e$ ions at grazing incidence ($1-10^\circ$). The resulting...

Thomaz, Raquel (PUCRS)9/24/26, 4:40 PMMAT Collaboration MeetingOral
Radiation effects in polymers span a wide range of chemical and structural modifications, depending on the energy deposited by the ion and on the dimensions of the material. Our research has focused on polymer thin films as model systems for investigating these effects under controlled conditions of film thickness and ion irradiation. Over the past years, we have explored a broad range of...

Over the past decades, the effects of swift heavy ion (SHI) irradiation have been extensively studied across a wide range of materials. Most of these investigations have focused on bulk materials, providing fundamental insights into irradiation-induced processes and supporting the development of materials for high-radiation environments such as nuclear facilities, particle accelerators, and...

Rothard, Hermann (CIMAP-Ganil CNRS CEA)9/24/26, 5:20 PMMAT Collaboration MeetingOral
In cold space environments, the synthesis of organic molecules can occur following radiolysis of small molecules (H2O, CO, CH4, NH3 etc.) on cold surfaces like dust grains (molecular clouds) and icy bodies of the solar system [1].

In this talk, we will provide an overview of the irradiation and in situ analysis facilities present at the beamline M3 at UNILAC. A focus will be on recent projects and developments related to questions in astrochemistry - from a detailed view on the radiolysis of complex organix molecules to effects of space weathering on cosmic dust analogues [1,2].
Moreover, we will provide a short...
