Electron-induced ligand loss from iron tetracarbonyl methyl acrylate

Autor: Hlib Lyshchuk, Atul Chaudhary, Thomas F. M. Luxford, Miloš Ranković, Jaroslav Kočišek, Juraj Fedor, Lisa McElwee-White, Pamir Nag

Publikováno v: Beilstein Journal of Nanotechnology, Vol 15, Iss 1, Pp 797-807 (2024)

We probe the separation of ligands from iron tetracarbonyl methyl acrylate (Fe(CO)4(C4H6O2) or Fe(CO)4MA) induced by the interaction with free electrons. The motivation comes from the possible use of this molecule as a nanofabrication precursor and f

Low-energy electrons transform the nimorazole molecule into a radiosensitiser

Autor: Rebecca Meißner, Jaroslav Kočišek, Linda Feketeová, Juraj Fedor, Michal Fárník, Paulo Limão-Vieira, Eugen Illenberger, Stephan Denifl

Publikováno v: Nature Communications, Vol 10, Iss 1, Pp 1-7 (2019)

Radiosensitisers are believed to interfere with cancer cells by dissociating upon interaction with electrons. Here the authors observe instead that the dominant path for nitroimidazolic radiosensitisers involves formation of a non-dissociated radical

Suppression of low-energy dissociative electron attachment in Fe(CO)5 upon clustering

Autor: Jozef Lengyel, Peter Papp, Štefan Matejčík, Jaroslav Kočišek, Michal Fárník, Juraj Fedor

Publikováno v: Beilstein Journal of Nanotechnology, Vol 8, Iss 1, Pp 2200-2207 (2017)

In this work, we probe anion production upon electron interaction with Fe(CO)5 clusters using two complementary cluster-beam setups. We have identified two mechanisms that lead to synthesis of complex anions with mixed Fe/CO composition. These two me

Absolute Dissociative Electron Attachment Cross Sections in Acetylene and its Deuterated Analogue

Autor: Olivier May, Juraj Fedor, Michael Allan

Publikováno v: CHIMIA, Vol 64, Iss 3 (2010)

An instrument for the measurement of absolute dissociative electron attachment cross sections was constructed and applied to two prototype molecules, acetylene (C2H2) and deuterated acetylene (C2D2). The isotope effect at the first dissociative elec

Role of the Molecular Environment in Quenching the Irradiation-Driven Fragmentation of Fe(CO)5: A Reactive Molecular Dynamics Study

Autor: Benjamin Andreides, Alexey V. Verkhovtsev, Juraj Fedor, Andrey V. Solov’yov

Publikováno v: The Journal of Physical Chemistry A. 127:3757-3767

Irradiation-driven fragmentation and chemical transformations of molecular systems play a key role in nanofabrication processes where organometallic compounds break up due to the irradiation with focused particle beams. In this study, reactive molecu

Publikováno v: Ovad, T, Sapunar, M, Sršeň, Š, Slavíček, P, Mašín, Z, Jones, N C, Hoffmann, S V, Ranković, M & Fedor, J 2023, ' Excitation and fragmentation of the dielectric gas C 4 F 7 N: electrons vs. photons ', The Journal of Chemical Physics, vol. 158, no. 1, 014303 . https://doi.org/10.1063/5.0130216

C4F7N is a promising candidate for the replacement of sulfur hexafluoride as an insulating medium, and it is important to understand the chemical changes initiated in the molecule by collision with free electrons, specifically the formation of neutra

It is well established that an isolated benzene radical anion is not electronically stable. In the present study, we experimentally show that electron attachment to benzene clusters leads to weak albeit unequivocal occurrence of a C
