Chattez avec Graph Search

Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.

AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.

Geomechanical stability issues may arise due to induced thermal stresses because CO2 will generally reach the storage formation at a temperature lower than that of the reservoir. Cold injection will form a cold region around the injection well, which will ...

Coupled Thermo-hydro-Mechanical Effects on Caprock Stability During Carbon Dioxide Injection

Lyesse Laloui, Chao Li

This study presents a numerical investigation of the effects of coupled material properties on the caprock stability. A thermo-hydro-mechanical framework is proposed in order to reproduce the physical processes. The results indicate that for a given geomet ...

Impact of material properties on caprock stability in CO2 geological storage

Lyesse Laloui, Chao Li

In this study, thermo-hydro-mechanical coupled simulations are performed to investigate caprock stability under cooling and pressurization during the injection of carbon dioxide. It is shown that failure potential of caprock increases with a higher value o ...

Impact of thermally induced soil deformation on the serviceability of energy pile groups

Lyesse Laloui, Alessandro Francesco Rotta Loria

This paper expands on the impact of the thermally induced deformation of the soil on the serviceability mechanical performance (i.e., deformation-related) of energy pile groups. The work is based on the results of a full-scale in-situ test that was perform ...

Engineering the self-assembly of diketopyrrolopyrrole-based molecular semiconductors via an aliphatic linker strategy

Kevin Sivula, Nestor Guijarro Carratala, Xavier Adrian Jeanbourquin, Xiaoyun Yu, Andrea Gasperini, Emilie Aude Marie Ripaud

The solid-state self-assembly of molecular semiconductors is a key aspect for controlling the optoelectronic properties of organic electronic materials. Herein, we investigate the use of a flexible linker strategy to control the self-assembly of a solution ...

Perovskite solar cells with CuSCN hole extraction layers yield stabilized efficiencies greater than 20%

Michael Graetzel, Shaik Mohammed Zakeeruddin, Mohammad Ibrahim Dar, Neha Arora, Norman Pellet

Perovskite solar cells (PSCs) with efficiencies greater than 20% have been realized only with expensive organic hole-transporting materials. We demonstrate PSCs that achieve stabilized efficiencies exceeding 20% with copper(I) thiocyanate (CuSCN) as the ho ...

Impact of thermally induced stresses on fracture stability during geological storage of CO2

Lyesse Laloui, Victor Vilarrasa Riano

Elsevier2016

The crystal structures of silver(I) sulphate, Ag2SO4, have been investigated as a function of temperature. A main feature is the phase transition from the low-temperature ordered phase, F ddd, to the high-temperature disordered phase, P63/mmc. In particula ...
