Photo-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, ...
Elsevier2024Development of Ti-Zr-Mn based AB 2 type metal hydrides alloys for an 865 bar two-stage hydrogen compressor
Andreas Züttel, Noris André Gallandat, Rui Li
This study reports the development of a new Ti-Zr-Mn-based AB 2 type hydrogen storage alloys for a two-stage metal hydride hydrogen compressor (MHHC). The hydrogen storage alloys are designed to compress hydrogen from 35 to 865 bar within a temperature dif ...
Pergamon-Elsevier Science Ltd2024Phase Transformation-Induced Interfacial Debonding of Silica Inclusions in Iron
Andreas Mortensen, David Hernandez Escobar, Julie Nathalie S Gheysen, Alejandra Inés Slagter
We document that in unstressed, undeformed, samples of pure iron containing silica inclusions precipitated by melt deoxidation, the iron matrix and a small fraction of the silica inclusions are locally separated at room temperature by a void. Thermal cycli ...
New York2023Room-temperature strength of the interfacial bond between silica inclusions and iron
Andreas Mortensen, David Hernandez Escobar, Alejandra Inés Slagter, Sergio Perosanz Amarillo
The strength of the interface between iron (Fe) and individual spherical silica (SiO2) inclusions of 5 +/- 1 mu m diameter is measured by means of in-situ micro-cantilever bending tests conducted under displacement control within a scanning electron micros ...
Oxford2023Enhanced Leaching of Zinc Ferrite by the Formation of a Solid Solution With Magnetite in Hydrochloric Acid Solution
The high zinc and iron contents of electric arc furnace (EAF) dust in the forms of zinc ferrite (ZnFe2O4) and magnetite (Fe3O4) make it a valuable secondary source of these metals. ZnFe2O4 and Fe3O4 are known to form a solid solution at all compositions, a ...
SPRINGER2023Micromechanics of oxide inclusions in ferrous alloys
Oxide inclusions are inevitably present in steel as a direct consequence of the steelmaking process; as a result, a cubic centimetre of modern steel will generally contain about a million of these hard and brittle micrometre-sized ceramic particles. Inclus ...
EPFL2023Design of New Low-Carbon Floor Systems by Reusing Cut Cast-in-Place Concrete Pieces
Corentin Jean Dominique Fivet, Célia Marine Küpfer, Numa Joy Bertola
As floors typically account for the largest share of a building embodied carbon footprint, new strategies to build low-carbon floors must be developed and implemented. Among these strategies, the reuse of existing components is a promising circular approac ...
Novus Press2023Prediction of crack nucleation and propagation in porous ceramics using the phase-field approach
The relevance of the phase-field approach to simulate the fracture in porous ceramics has been investigated. For this purpose, the conditions for the crack initiation using the phase-field model have been compared to the theoretical predictions of the coup ...
ELSEVIER2022Processing and micro-mechanical characterization of multi-component transition MC carbides in iron
Andreas Mortensen, Goran Zagar, Léa Deillon, Marta Fornabaio, Lionel Michelet
We prepare multi-component transition monocarbides of chosen composition by arc-melting together a pre-alloy of the transition metals and cast iron. Based on the elements Ti, Ta, V, Nb and W, 51 different binary, ternary and quaternary compositions are pro ...
2021The effect of stress triaxiality on the phase transformation in transformation induced plasticity steels: Experimental investigation and modelling the transformation kinetics
Helena Van Swygenhoven, Efthymios Polatidis, Nicola Casati
In situ multiaxial loading during neutron diffraction tests were undertaken on a low-alloyed Quenched and Partitioning (Q&P) Transformation Induced Plasticity (TRIP) Bainitic Ferrite (TBF) steel with dispersed austenite particles. The effect of stress tria ...
