Unique corrosion behavior of an archaeological Roman iron ring: Microchemical characterization and thermodynamic considerations
Stefano Mischler, Laura Brambilla
The corrosion mechanisms of a Roman iron bezel ring were investigated by in-depth characterization of its uncommon corrosion pattern and thermodynamic modelling. A silver foil and altered glass remnants were identified, covered with thick strata of magneti ...
2024Photo-Fenton inactivation of MS2 bacteriophage at alkaline pH by Fe salts or nm to μm-sized oxides, and the Janus-faced effects of natural organic matter in surface waters
César Pulgarin, Stefanos Giannakis, Giulio Farinelli, Ogadimma Cassandra Oji-Okoro
In this study, MS2 bacteriophage was inactivated by homogeneous and heterogeneous photo-Fenton processes in an alkaline matrix (pH 8) using low concentrations of H2O2 and iron forms (1 mg/L), including Fe(II), Fe(III), and Fe (hydr)oxides. As a reference, ...
Elsevier2024Spin wave dispersion of ultra-low damping hematite ( α−Fe2O3 ) at GHz frequencies
Dirk Grundler, Mohammad Hamdi, Ferdinand Rémy Hynek Posva
Low magnetic damping and high group velocity of spin waves (SWs) or magnons are two crucial parameters for functional magnonic devices. Magnonics research on signal processing and wave-based computation at GHz frequencies focused on the artificial ferrimag ...
2023Spin wave dispersion of ultra-low damping hematite (α-Fe2O3) at GHz frequencies
Dirk Grundler, Mohammad Hamdi, Ferdinand Rémy Hynek Posva
Raw data associated to the manuscript ‘’Spin wave dispersion of ultra-low damping hematite (α-Fe2O3) at GHz frequencies‘’, Physical Review Materials 7, 054407(2023); doi: 10.1103/PhysRevMaterials.7.054407 Information about file fo ...
Zenodo2023Broadband spectroscopy and inelastic light scattering on the canted antiferromagnet hematite for antiferromagnetic magnonics
Collective spin excitations propagating in magnetically ordered materials are called spin waves (SWs) or magnons. They are promising for low-power and beyond-CMOS information processing, which do not suffer from the ohmic losses. SWs in ferromagnets (antif ...
EPFL2023Persistence of the isotopic signature of pentavalent uranium in magnetite
Rizlan Bernier-Latmani, Barbora Bártová, Zezhen Pan
Original data pertaining to the manuscript 'Persistence of the isotopic signature of pentavalent uranium in magnetite' published in Environmental Science and Technology by Zezhen Pan, Yvonne Roebbert, Aaron Beck, Barbora Bartova, Tonya Vitova, Stefan Weyer ...
EPFL Infoscience2022Increasing Magnetic Anisotropy in Bimetallic Nanoislands Grown on fcc(111) Metal Surfaces
Harald Brune, Stefano Rusponi, Sergio Vlaic, Dimitrios Mousadakos
The magnetic properties and the atomic scale morphology of bimetallic two-dimensional nanoislands, epitaxially grown on fcc(111) metal surfaces, have been studied by means of Magneto-Optical Kerr Effect and Scanning Tunneling Microscopy. We investigate the ...
MDPI2022Cluster Catalysis with Lattice Oxygen: Tracing Oxygen Transport from a Magnetite (001) Support onto Small Pt Clusters
Wolfgang Harbich, Giulia Elisabetta Pacchioni, Ke Zhang
Oxidation catalysis on reducible oxide-supported small metal clusters often involves lattice oxygen. The present work aims at differentiating whether the reaction takes place at the cluster/support interface or on the cluster. To that purpose, we trace the ...
AMER CHEMICAL SOC2021Iron phosphate mediated magnetite synthesis: a bioinspired approach
The biomineralization of intracellular magnetite in magnetotactic bacteria (MTB) is an area of active investigation. Previous work has provided evidence that magnetite biomineralization begins with the formation of an amorphous phosphate-rich ferric hydrox ...
ROYAL SOC CHEMISTRY2021Impact of iron reduction on the metabolism of Clostridium acetobutylicum
Vassily Hatzimanikatis, Karin Lederballe Meibom, Zhaleh Hosseini, Cornelia List
Iron is essential for most living organisms. In addition, its biogeochemical cycling influences important processes in the geosphere (e.g., the mobilization or immobilization of trace elements and contaminants). The reduction of Fe(III) to Fe(II) can be ca ...
