The interest in the electron impact-induced ligand release from MeCpPtMe3 [trimethyl(methylcyclopentadienyl)platinum(IV)] is motivated by its widespread use as a precursor focused and ion beam nanofabrication. By experimentally studying impact dissociative ionization of under single-collision conditions, we have found that removal two methyl radicals energetically more favorable than one radical even comparable to nondissociative MeCpPtMe3. This observation explained structural rearrangement...
Abstract We studied free electron collision-induced fragmentation of HFO1234ze(E) (C3H2F4). The motivation
of the present study is to assess possibility using this gas in resistive plate chamber
detectors and for interest its electron-induced decomposition. Two electron-collision setups,
which complement each other, are used. Additionally, interpretation data supported
by quantum chemical calculations. provide absolute partial cross sections both...
We probe the separation of ligands from iron tetracarbonyl methyl acrylate (Fe(CO)
DNA origami nanoframes with two parallel sequences are used to evaluate the effect of nucleoside substituents on radiation-induced damage. Double strand breaks (DSB) counted using atomic force microscopy (AFM), and total number lesions is evaluated real-time polymerase chain reaction (RT-PCR). Enhanced AT or GC content does not increase breaks. Incorporation 8-bromoadenosine results in highest enhancement lesions; however, DSB observed for 2′-deoxy-2′-fluorocytidine, indicating different...
Abstract The present work is a continuation of our studies with iron pentacarbonyl, model organometallic precursor for Focused Ion Beam-Induced Deposition (FIBID). Interactions He2+(16 keV), Ne+(6 Ne4+(40 Ar2+(12 keV) and Ar8+(64 projectile ions [Fe(CO)5]n clusters are studied using TOF mass spectrometry. represent an intermediate between the gas phase bulk environment can be used as proxy processes in complex environments such e.g. nanostructure deposition. addition study results...
