72As is a β+-emitter (T1/2 = 26.0 h; Eβ+ = 1.17 MeV,Iβ+ = 87.8 %) that can be produced at a cyclotron and has significant potential for use in PET studies. Experiments have been undertaken to determine its positron emission intensity with greater precision. [...]

Fibroblast activation protein (FAP) is almost exclusively expressed on cancer-associated stromal cells, making it apromising target for tumor imaging by positron emission tomography (PET). While 68Ga- or Al[18F]F-labeled FAPinhibitors (FAPIs) have been characterized in detail, the potential advantages of FAPIs containing a covalentlybound 18F-label remain largely unknown. [...]

Progress in the development of CO2 reductioncatalysts has revealed more stable and selective options for solarfuel production. In most cases, the catalysts are tested under steady-state conditions. [...]

Iridium oxides display state-of-the-art electrocatalysts for anodes in proton exchange membrane water electrolyzers (PEM-WE), combining electrocatalytic activity for the oxygen evolution reaction (OER) and reasonable stability. During OER with liquid electrolytes, iridium dissolution rates were reported as orders of magnitude higher than those of operating PEM-WE cells, while the reasons for these differences are not well understood.
