Impact of CO2-rich seawater injection on the flow properties of basalts
Lyesse Laloui, Eleni Stavropoulou, Cesare Griner
Permanent CO storage in basalts through mineralisation offers a promising solution for reducing carbon emissions and mitigating climate change. This study focuses on the impact of potential mineralisation on the flow properties of the basaltic material. Fl ...
2024Effect of wettability and textile architecture on fluid displacement and pore formation during infiltration of carbon fibrous preforms
Véronique Michaud, Baris Çaglar, Helena Luisa Teixido Pedarros
We seek to address how air entrapment mechanisms during infiltration are influenced by the wetting characteristics of the fluid and the pore network formed by the reinforcement. To this end, we evaluated the behavior of two model fluids with different surf ...
London2023Liquid metal infiltration of silicon based alloys into porous carbonaceous materials. Part II: Experimental verification of modelling approaches by infiltration of Si-Zr alloy into idealized microchannels
Ludger Weber, Caroline Hain, Giovanni Bianchi, Alberto Ortona, Manoj Kondibhau Naikade
In this work, the mechanisms leading to the pore closure in reactive melt infiltration (RMI) of carbon by pure silicon and a near eutectic Si-8 at-pct Zr alloy at 1500 and 1700 degrees C under vacuum were studied. Various geometrical configurations of micr ...
ELSEVIER SCI LTD2022Cross verified independent measurements of correlated bubble property distributions as part of the scale-up of a catalytic bubbling fluidized bed reactor
Methanation can be applied as part of a Power-to-Gas (PtG) concept to store renewable electricity. Using a catalytic bubbling fluidized bed (BFB) methanation reactor allows a flexible and economic operation. Properties of bubbles rising through the fluidiz ...
EPFL2022Operando X-ray diffraction during laser 3D printing: from machine design to experiments and computer simulations
The importance of additive manufacturing, also known as 3D printing, has grown exponentially in the recent years thanks to its high flexibility to manufacture intricate parts. This process can be divided into many different sub-categories, depending on the ...
EPFL2020How to weave a perfect sphere with curved strips
Mark Pauly, Tian Chen, Yingying Ren
Triaxial weaving, a craft technique that enables the generation of surfaces with tri-directional arrays of initially straight elastic strips, has long been loved by basket makers and artists seeking a combination of practical and aesthetically-pleasing str ...
American Physical Society2020Biomedical optical techniques for intracochlear cellular imaging
Imaging the inner ear microanatomy is of great importance for the assessment of the state of the cells responsible for sound detection. Hearing disorders are mainly due to a malfunction of the cochlea, the bone containing the cells inside the inner ear. Un ...
EPFL2019Mechanical anisotropy of Opalinus Clay shale: a multiscale approach
Lyesse Laloui, Alessio Ferrari, Eleonora Crisci, Aldo Madaschi
The mechanical properties of Opalinus Clay shale are strongly affected by the mineralogical composition of the layers and by their spatial arrangement at centimetre to decimetre scales. For this reason, accurate laboratory characterization of the mechanica ...
LMS-EPFL2018In Situ Synchrotron X-Ray Diffraction and Small Angle X-Ray Scattering Studies on Rapidly Heated and Cooled Ti-Al and Al-Cu-Mg Alloys Using Laser-Based Heating
Helena Van Swygenhoven, Steven Van Petegem, Christian Leinenbach, Patrick Schloth
Beam-based additive manufacturing (AM) typically involves high cooling rates in a range of 10(3)-10(4) K/s. Therefore, new techniques are required to understand the non-equilibrium evolution of materials at appropriate time scales. Most technical alloys ha ...
Springer2016Multiphase-Field Modeling of Micropore Formation in Metallic Alloys
Michel Rappaz, Alain Jacot, Hossein Meidani
A 3D phase-field (PhF) model has been developed to study the formation of micropores constrained to grow within a well-developed solid network. The model accounts for the equilibrium condition at triple (solid-liquid-pore) lines and the partitioning of dis ...
