Factors influencing the hydration kinetics of ye'elimite; effect of mayenite
Karen Scrivener, Mohsen Ben Haha, Frank Bullerjahn
The aim of this study was to understand the origin of the variation in the hydraulic reactivity of ye'elimite systems. To this end, the hydration of two clinkers, one composed mainly of synthetic stoichiometric (C(4)A(3)(S) over bar) "Y" and the other of a ...
PERGAMON-ELSEVIER SCIENCE LTD2019Laboratory electromagnets: from the beginnings to Electromagnet Laboratories
The mechanical action on iron of the first horseshoe electro-magnets (1824) was obvious. Their use to investigate more subtle magnetic, magneto-optical, atomic or nuclear properties of matter began in 1845 with Faraday. Until the first iron-less Bitter mag ...
2019Method of synthesis of an electrode for use as a catalyst of oxygen evolution reaction
Xile Hu, Fang Song, Elitsa Petkucheva
Disclosed are methods of synthesis of an oxidized nickel foam electrode incorporating iron including the step of subjecting a nickel foam electrode to repetitive cyclic voltammetric scans in a basic solution containing iron. Also disclosed is an oxidized n ...
2018Ultra low cycle fatigue of welded steel joints under multiaxial loading
Albano António De Abreu E Presa De Castro E Sousa
Extreme loading scenarios such as earthquakes, exceptional wind gusts or tides are characterized by very high amplitude and multidirectional cyclic loads applied to a structure. Ultra Low Cycle Fatigue (ULCF) arises in such cases and can be summarily defin ...
EPFL2017Recent Advances in the Synthesis and Applications of Multimodal Gold-Iron Nanoparticles
Bimetallic particles based on gold and iron have been gathering increasing interest in biomedical applications because of the synergic combination of the plasmonic features of the inert gold component with the magnetic properties of the iron or iron oxide ...
Bentham Science Publishers2017Atomistic study of hydrogen embrittlement of grain boundaries in nickel: I. Fracture
Hydrogen ingress into a metal is a persistent source of embrittlement. Fracture surfaces are often intergranular, suggesting favorable cleave crack growth along grain boundaries (GBs) as one driver for embrittlement. Here, atomistic simulations are used to ...
Elsevier2017Iohexol degradation in wastewater and urine by UV-based Advanced Oxidation Processes (AOPs): Process modeling and by-products identification
Hubert Girault, César Pulgarin, Natalia Gasilova, Stefanos Giannakis, Milica Jovic, Simon Schindelholz, Miquel Pastor Gelabert
In this work, an Iodinated Contrast Medium (ICM), Iohexol, was subjected to treatment by 3 Advanced Oxidation Processes (AOPs) (UV, UV/H2O2, UV/H2O2/Fe2+). Water, wastewater and urine were spiked with Iohexol, in order to investigate the treatment efficien ...
Elsevier2017Intrinsic structural transitions of the pyramidal I < c plus a > dislocation in magnesium
The stability of a mixed < c + a > dislocation on the pyramidal I plane in magnesium is studied using molecular dynamics simulations. The dislocation is metastable and undergoes a thermally-activated transition to either a sessile, basal-dissociated < c + ...
Pergamon-Elsevier Science Ltd2016Crack tip blunting and cleavage under dynamic conditions
William Curtin, Varun Parameswaran Rajan
In structural materials with both brittle and ductile phases, cracks often initiate within the brittle phase and propagate dynamically towards the ductile phase. The macroscale, quasistatic toughness of the material thus depends on the outcome of this micr ...
Elsevier2016Intrinsic structural transitions of the pyramidal I 〈c+a〉 dislocation in magnesium
The stability of a mixed < c + a > dislocation on the pyramidal I plane in magnesium is studied using molecular dynamics simulations. The dislocation is metastable and undergoes a thermally-activated transition to either a sessile, basal-dissociated < c + ...
